Protecting the Rivers that Connect Us

Protecting the Rivers that Connect Us

Conserving riparian habitat (habitat near rivers, streams and lakes) is a key element in the protection of terrestrial and marine habitats, since these ecosystems are closely connected.

The state of river conservation in the South Caribbean is concerning. The biodiversity of freshwater ecosystems faces different levels of threats, from the wastewater that makes its way to rivers, to the deforestation of river banks, to the pollution caused by excess nitrates and phosphates used in agriculture.

These combined threats are causing a decline in the biodiversity of the riparian areas: critical habitat for sloths, white-faced monkeys, howler monkeys, birds and many other species necessary for the balance and health of the ecosystem. Therefore, we must protect and conserve these important areas.

Caring for rivers

The care and maintenance of rivers not only helps sloths and other wildlife in the area but also directly contributes to the conservation of marine species and the protection of coral reefs.

For example, by reforesting riparian and coastal areas, we gradually reduce the amount erosion and sediment that runs down the rivers. Once this sediment reaches the ocean, it covers coral reefs and prevents the symbiotic algae (zooxanthella) that lives within them from carrying out photosynthesis.

As trees grow they also help to reduce ocean acidification by absorbing the CO2 that would be taken up by the ocean. In addition to using carbon, these trees help to absorb the excess nutrients that go down the river, that cause an excessive growth of algae on the reefs.

Excess nutrients (such as nitrates and phosphates) can lead to algal overgrowth, stunting the growth of coral and eventually leading to its demise/Photo by U.S. National Oceanic and Atmospheric Administration from Wikimedia Commons

Moreover by planting trees, we also help to maintain a healthy and connected ecosystem for tree-dwelling species such as two and three-fingered sloths.

Protecting downstream ecosystems

Cleaning the areas adjacent to rivers prevents a large amount of materials and plastics from harming marine life, such as dolphins, turtles, fish etc. that often ingest plastics thinking they are food or get caught in plastic debris.

As we can see, the terrestrial and marine worlds are inextricably linked and riparian habitat plays a fundamental role in the health of both ecosystems. With the right conservation practices put in place, we can have a very positive impact not only on these vital river habitats but also on the biodiversity of the whole ecosystem.

Urban Sloth Project: the impacts of habitat disturbance

Urban Sloth Project: the impacts of habitat disturbance

The Urban Sloth Project is a long-term investigation into the impacts of habitat disturbance and rainforest urbanization on the behavior of wild sloths in Costa Rica.

Many people believe that Costa Rica is the best place in the world for seeing sloths – and for good reason; you are almost guaranteed to see a sloth if you visit this tiny Central American country!

Unfortunately, we suspect that this is a sign of a much bigger problem.

Sloths in healthy environments are hard to see

In an ideal situation, sloths would live in primary rainforests, where the multi-story canopy interlocks and trees are shrouded in extensive epiphyte growth. In this environment, sloths are perfectly camouflaged and become practically invisible, hiding in the dense foliage at the top of gigantic trees.

Unfortunately, the remaining primary rainforests are dwindling as deforestation escalates, and sloths no longer have access to their preferred habitats. They are being forced to exist in increasingly urbanized environments, and here they cannot hide!

Sloths are slow-moving, habitual animals and are therefore very sensitive to changes in the environment. They are unable to run or jump to traverse gaps between trees, and so habitat fragmentation creates a lot of problems.

While trying to navigate an increasingly urbanized world, sloths are being electrocuted on powerlines, attacked by dogs, hit by cars, and exploited by humans.

Sloths in Costa Rica are now considered to be of conservation concern due to habitat loss from agriculture, livestock production, and the increasing urbanization of the rainforest. In line with this, sloths are the most frequently admitted species to rescue centers in Costa Rica.

A massive lack of information on wild sloth behavior

Such a lack of knowledge makes it very challenging for us to develop effective methods to conserve sloths – it is very difficult to protect something that you don’t know anything about!

For two-fingered sloths, in particular, even basic data on the natural history and ecological requirements of the species is lacking. For example, information on the habitat preference, ranging patterns, population densities, diet, and reproductive behavior of this genus is incredibly scarce, and for some sloth species, is completely absent.

There is a massive lack of information on the ecology of wild two-fingered sloths


With current extinction rates indicating that we are in the midst of sixth mass extinction, a lack of knowledge covering the basic ecological requirements of a species is of concern due to the profound implications for the development of future conservation strategies.

Monitoring 32 sloths

The Urban Sloth Project aims to compare the behavior and activity budgets of sloths living in highly urbanized areas with those sloths living in healthier environments (protected primary rainforests).

Over the next 5 years, we will be tracking and monitoring 32 sloths (16 three-fingered sloths, and 16 two-fingered sloths) using VHF radio collars and compact data loggers. The results will be used to develop effective conservation strategies that will help humans and sloths peacefully coexist.


The data collected will help us to determine:

  • Amount of time spent active vs inactive.
  • Amount of time spent engaging in different behaviors.
  • Home range size.
  • Distance traveled per day.
  • Dietary preferences.
  • Amount of time spent traveling in the canopy vs traveling on the ground.
  • Circadian rhythm of activity – How sloth activity is impacted by the environmental conditions (temperature, humidity, wind speed, rainfall, moon phase).

To protect sloths, we must first understand them

The knowledge we gain from this project will enable SloCo to make meaningful changes to the lives of sloths living in rapidly changing environments. For example, we will be able to identify which tree species are most important for sloths living in urban areas, and we can make sure that these species are protected and replenished.

We will also be able to identify areas where canopy connectivity needs to be improved to aid sloth dispersal via the installation of wildlife bridges and through targeted reforestation efforts.

You can follow The Urban Sloth Project through our social media platforms (Facebook, Instagram, or Youtube), and also by becoming a Very Important Partner with a monthly subscription to support this project!

This project is only possible due to the generosity and kindness of our supporters – thank you for being a part of Team Sloth!

Three-fingered sloth ‘adopts’ a two-fingered sloth baby!

Three-fingered sloth ‘adopts’ a two-fingered sloth baby!

These two sloths are not only different species, but they belong to two completely different families, separated by over 30 million years of evolution. Cross-species adoptions like this are incredibly rare in the wild, with only 3 other documented observations of this happening.

What happened?

On the 20th December 2020, Gerald Pereira and Oscar Solano Rojas were guiding a group of tourists in Costa Rica. Sloths are a common sight on these tours, but that day they saw something that they had never seen before – nestled quietly amongst the rainforest canopy they spotted an adult three-fingered female tending to a two-fingered baby sloth.

Gerald and Oscar, both with over 11 years of experience working as ecotourism guides, knew they had witnessed something important.

The curious pair were observed in a fragmented strip of rainforest, sandwiched between a river, a pineapple plantation and a busy road. According to Oscar, “in that area, local people take great care of the sloths, so we always go to look there because there is a very large population”.

“Yesterday we started the tour, which we call the ‘Sloth Tour’, as usual. To see them active in the early hours of the day, we started the tour at 6am. Around 8am we arrived at a place where my partner Gerald and I saw a sloth hanging from a Cecropia tree. At first, it did not attract much attention, we saw that she was a female and a baby, but that morning we had already seen 3 baby sloths, and we did not think it was anything special or different from what we had seen. When we paid more attention to them, however, we discovered that it was a three-fingered female and a two-fingered baby.”

“I had already seen the two species in the same tree many times, and at first we thought it was just a coincidence that they were there together. When we found them it seemed like they were waking up. They both started scratching, and then the baby separated from the female, fed on cecropia leaves a little, and I thought that was the end of the interaction.”

“But then you see how the baby returns to the female, and she receives it with total naturalness, that is what surprised us the most. None of us who were there could believe it, neither Gerald nor I, because we had never seen it before. It left me astonished. In rescue centres, I had seen a certain attachment between the two species, but never in their natural habitat, as happened to us yesterday.”

As can be seen in the video footage captured by Gerald and Oscar, it does indeed appear that the two sloths interact with the gentle tenderness of a mother-baby relationship. When they returned to the area the next day, they once again found the pair snuggling together in a shady spot in the canopy. It certainly looks like the bond between these two sloths is much more than just a fleeting interaction. It appears as though the female has formally adopted this baby as her own.

Odd Alliances

Adult animals adopting unrelated young is nothing new to science, but in most cases these are intraspecies interactions – meaning that they occur between two unrelated individuals of the same species. This has most commonly been observed within sociable species, often herd or pack animals.

Interspecies adoptions – where a female adopts a baby of a different species – is an altogether much rarer occurrence in the wild. In fact, there have only ever been 3 other documented instances of this happening, and it has never before been observed in sloths. 

In 2004, a group of capuchin monkeys were documented caring for a baby marmoset, and in 2014 a bottlenose dolphin adopted a baby melon-headed whale and nurtured it for it for 3 years. More recently, a lioness in India was found to have adopted an orphaned leopard cub in 2018 and she raised it alongside her own offspring.

Why do cross-species adoptions occur?

In evolutionary terms, caring for another animal’s offspring like this doesn’t make much sense. Raising a baby demands a lot of time and energy (something which a sloth has a limited supply of), and it is usually done with the purpose of propagating an individual’s own genes. So why do cross-species adoptions like this sometimes happen?

The truth is, scientists are still trying to understand it. Because these events are so rare, there isn’t much information available and each observed case appears to be very different. There are two popular theories:

  1. Instinct: A lot of adult female animals are biologically hardwired through evolution to care for helpless infants. A cross-species adoption might occur accidentally after a female has recently given birth herself, when high levels of the hormone oxytocin encourage her to bond with the orphaned baby (even if it isn’t hers!).
  • Mutual benefit: If the benefits of the raising an unrelated baby outweigh the costs, this could explain why some interspecies adoptions take place. For example, it could be beneficial for a group of animals to add a new individual that would help to secure more food, or provide added protection. In some social species the simple benefit of companionship may be a driving force! This is unlikely to be an important factor for our solitary sloths though.

How did this happen?

The circumstances surrounding this adoption are not entirely clear, but SloCo founder and sloth expert Dr. Rebecca Cliffe has some ideas about what might have led to this unusual event.

“This is the first time that anything like this has ever been seen before in wild sloths, and it is certainly very interesting. I am used to sloths surprising us, but this has to be one of the most unusual things I have heard about. I suspect there are three possible scenarios which may have led to this happening:

1) Accidental human interference. Maybe someone found the baby sloth alone and tried to ‘reunite’ it with its mother, but accidentally paired it with the wrong sloth. Reuniting baby sloths with their mothers is a surprisingly common requirement for people in Costa Rica as babies are often found alone on the ground after falling from the tree.

A lot of people don’t realise that there are two very different types of sloth, and so they might not have realised what they were doing. In this situation, however, I would expect the adult sloth to reject the baby and so this feels like an unlikely scenario

2) The baby sloth lost it’s own mother, and instinctively clung onto the fur of another sloth. Baby sloths are born with a strong instinct to cling onto mom’s fur, and if they are separated, they tend to cling onto the next best thing. It isn’t impossible to think that this baby may have climbed onto the three-fingered sloth after becoming orphaned. However, in this situation I would also expect to see the adult sloth looking agitated and stressed out by her new uninvited companion – and I doubt the relationship would last more than a few hours.

3) The baby sloth lost its own mother, and the adult sloth recently lost a baby of her own. This unusual combination of events would provide a feasible opportunity for the pair to bond naturally due to a mixture of instincts and hormones. Although extremely rare, I think this is probably the most likely scenario!”

What happens next?

This unprecedented behavior leaves all of us with many questions – particularly regarding the welfare of both sloths! Will the baby survive? It’s certainly possible. While they are different species, they do share a broadly similar ecology.

The diets of both sloths overlap heavily, with both being predominantly folivorous (eating only leaves). Two-fingered sloths tend to be more flexible and adaptive with their choices, while three-fingered sloths are more selective about what types of leaf they will eat. With both species, babies maternally inherit knowledge about which trees are safe to feed from – and this arrangement may work in the baby’s favor!

Furthermore, it appears as though the baby sloth is approximately 7 months old. At this age, the baby would not be as reliant upon a steady source of milk from the mother as the natural weaning process would be taking place. Although the adult female could be producing milk, we don’t think this is essential for the survival of the baby at this stage.

Two-fingered sloths are also much larger than their three-fingered counterparts when fully grown, which means that the adoptive mother may have a challenge on her hands when lugging around her overgrown offspring.

But what happened to the baby’s biological mother? This remains a mystery. Considering the location in which the pair were observed is highly disturbed, it may be that she got into trouble with the busy road or nearby pineapple plantation. Or perhaps there was an accidental baby mix-up, and somewhere in the rainforest, a mother two-fingered sloth is tenderly nurturing a baby three-fingered sloth. It’s doubtful we will ever know for sure.

While there are certainly a lot of challenges for this pair to overcome, here at SloCo we have high hopes for their survival. After the unprecedented global difficulties that 2020 has brought, we are happy to embrace this heart-warming story (which has all the makings of a future Disney movie!).



We will be working closely with both Gerald and Oscar to monitor the two sloths as time goes on – we will keep you updated on their progress! For now, we are keeping our fingers and toes crossed for a happy ending.

2021 Update:

It’s with a heavy heart that we must inform our supporters that the wild three-fingered sloth mom that was found to be caring for a two-fingered baby has passed away.

Local guides who were tracking the pair witnessed the mom and baby fall from their tree. Unfortunately, mom did not survive the fall. The baby was uninjured and climbed back up into the tree.

The guides continued to watch over the baby for the rest of the evening, and returned to the spot every day to check on him – but after three days he had ventured off on his own into the rainforest.

We estimate that the baby was around 8 months old, at which point he would naturally begin to distance himself from his mom. Team Sloth is optimistic that his two brilliant sloth moms taught him everything that he needs to know in order to survive in the wild!

Helping sloths by going plastic-free: 11 daily items you can change today!

Helping sloths by going plastic-free: 11 daily items you can change today!

July is plastic-free month. It is an opportunity to reflect on how we can reduce our plastic consumption, which not only harms our marine and terrestrial ecosystems but threatens our health as well.

The good news is you don’t have to reinvent the wheel! There are lots of helpful guides and websites filled with tips and plastic-free alternatives.

plastic-free sloths

So here are 11 daily items that you can exchange for plastic-free alternatives!

1) Plastic-free cigarettes

You have probably heard about plastic bags tragically making their way into marine ecosystems and filling the stomachs of sea turtles. However, the most littered item on Earth are cigarette butts which are the most frequently found item during beach clean ups.

The filters in cigarette butts can take up to 10 years to break down into smaller pieces (micro-plastics). As they break down they release nicotine and heavy metals into the environment.

Unfortunately, filters don’t improve lung health overall. There are some companies such as Greenbutts that manufacture biodegradable filters. However, even biodegradable filters will release their captured toxins upon breaking down.

So if you do smoke, you can reduce your daily use of plastic by opting for cigarettes without filters.

Cigarette butts end up in the digestive tracts of many kinds of wildlife/Source:

2) Plastic-free cotton swabs

Cotton swabs, cotton buds, Q-tips – they have a lot of names. Now even these single-use plastic products can be replaced by biodegradable alternatives!

plastic-free q

3) Plastic-free toothbrushes and toothpaste

Toothbrushes and tubes of toothpaste are a recurrent sources of plastic pollution. Fortunately, bamboo toothbrushes and refillable toothpaste jars are great substitutes!

plastic-free tooth brush
Feeling crafty? You can make toothpaste from scratch yourself using activated charcoal, bentonite clay, and peppermint essential oil (just be sure not to store it in a metal container)

4) Plastic-free razors

Like toothbrushes, disposable razors are common daily items that lead to an accumulation of plastic waste overtime. Although razors with replaceable heads are better than entirely disposable ones, there are razors that are plastic-free altogether! Paired with the right shaving cream, these plastic-free razors not only reduce your environmental footprint but minimize irritation due to the harsh chemicals found in most shaving foams.

5) Plastic-free face and body scrubs

Exfoliating (i.e. gently scrubbing away dead skin cells) is a great way to maintain skin health. There are a variety of face and body scrubs on the market, but many of them unfortunately contain plastic microbeads to to aid in this process. These microplastics are too small to be filtered out by water treatment plants and therefore wind up in our oceans. Fortunately a number of companies have already switched to biodegradable alternatives or have pledged to remove plastic microbeads from their products.

There are a variety of recipes for face and body scrubs you can make at home.

6) Shampoo bars

Unfortunately many cosmetics, in addition to being packaged in plastic, are made from chemicals that threaten the health of humans and ecosystems alike. If you are concerned about the products you are currently using you can look up their safety status at the Environmental Working Groups’s Skin Deep database (or download their app!).

Moreover, many shampoos are designed to strip the natural oils from your hair and replace them with synthetic substitutes. Transitioning from conventional shampoo to using a shampoo bar can take a bit of patience but the results (and the health benefits) are well worth it!

“Transitioning to plastic-free shampoo bars was the easiest change I made” –Plastic Freedom

7) Plastic-free makeup

You don’t have to sacrifice the glamour by going plastic-free. Whether your daily routine consists of a bit of concealer or a full face of makeup, there are a lot of exciting plastic-free products that are also free from the harmful chemicals found in traditional makeup.

61% of popular lipstick brands were found to contain lead. Fortunately refillable makeup free from harmful chemicals is now available in many places/Source: Plastic Freedom

8) Plastic-free menstrual products

Menstrual cups and reusable period underwear solve a lot of problems. They drastically reduce plastic waste and water consumption and ensure that people suffering from period poverty, have a safe, long-term method to manage periods and avoid missing out on school.

Surprisingly, pads are composed of 90% plastic and the amount of plastic packaging used for tampons can be equally shocking. Menstrual cups drastically reduce plastic consumption, generating 99.6% less plastic waste than disposable pads and 94% less plastic waste created by tampons.

Even 100% cotton tampons can generate a significant environmental impact as cotton crops require impressive amounts of water.

There are lots of plastic-free menstrual products, from reusable pads, to period underwear to menstrual cups/ Source:


9) Refillable cleaning products

Buying in bulk is a great way to reduce plastic usage. However, companies such as Neat, have come up with an even better way to reduce plastic waste.

Many cleaning products are 90% water. Neat sells reusable spray bottles and offers concentrated refills in glass bottles that can be recycled.

10) Plastic-free sandwich wraps

Whether or not you are a sandwich eater, these food wraps can be used for a variety of food items. You can even make reusable food wraps at home by choosing a bit of your favorite cloth and melting on some beeswax!

Try to avoid products made by bees? These vegan food wraps are made from wax that would otherwise be disposed of during food processing.

11) Reusable tote bags

Single-use plastic bags are infamous for their uncanny ability to end up in the most unexpected places. Even places as remote as Mount Everest are struggling with pollution due to single-use plastics!

If you want to reduce your plastic consumption whilst supporting sloth conservation you can treat yourself to a reusable sloth tote (now 30% off for Plastic Free July)!

Sloth starts using a wildlife bridge in record time

Sloth starts using a wildlife bridge in record time

This video of a three-fingered sloth using a wildlife bridge is the exciting result of the coordinated efforts of many people.  We installed a Sloth Crossing for her and she started using it in record time (less than a month!). You might think that a month is still quite a long time, but given that it takes 30 days for a sloth to digest a single leaf, this is quite a fast turn around!


We install Sloth Crossing wildlife bridges like this as part of our Connected Gardens program. These rope bridges connect trees on private properties, ensuring that sloths and other wildlife can safely access these important resources (without having to travel on the ground).


Helping a three-fingered sloth safely reach her favorite trees

This three-fingered sloth is a beloved resident of Annanci Village, a retreat for families visiting the South Caribbean. She spends much of her time nestled among the epiphytes and vines growing on a massive tree. Although the tree is no longer alive, it is covered by plants living on its branches, a perfect place for her to rest and remain hidden.


Her favorite tree to rest (if you look carefully in the second photo you can see her climbing up the trunk)/Photos: Katra Laidlaw


The owners of the property noticed that she frequently would come down from the tree and cross on the ground in order to access a Cecropia tree, a favorite food of sloths and monkeys alike.

Fortunately, there isn’t a dog living on the property that could attack her. However, crossing on the ground is a difficult and laborious process for sloths due to their unique and specialized muscle structure. She is also much more vulnerable to predators on the ground than suspended in the tree canopy.

Bridging the gap

The owners of the property reached out to Patricio Silfeni (Pato), our Connected Gardens manager, and asked if we could install a rope bridge to connect her two favorite trees.

Thanks to our talented tree climber, Gallo Adolfo, we were able to quickly install a Sloth Crossing to bridge the gap.

Creatures of habit

Sloths are habitual creatures. Once they have established a routine, they will follow the same route to the same trees. Sloths will spend their first year of life clutching to their mother’s chest, tasting the leaves that she eats, and learning her habits. Once they become independent, it is actually the mother that will find another home range, leaving her offspring to remain in the place where they were born.

Because they are such creatures of habit, it can be difficult to get sloths to modify their behavior.


An exciting discovery!

Foforo (Yorjes Salazar Elizondo), the manager of Annanci Village, was attending to some clients when he noticed that the sloth was using the rope bridge to reach the cecropia tree!

He ran to get his camera and was able to capture these wonderful photos of her using the bridge! Now she doesn’t have to cross on the ground, giving her easy access to her two favorite trees!

Bobby’s wildlife bridge: how sloth crossings help other species

At Faith Glamping, a unique camping experience for those visiting the South Caribbean, another dangerous situation for wildlife emerged. The owners noticed that a troop of howler monkeys would frequently visit the property, and in order to get across a gap in the trees, they would have to jump.

One time, when a mother howler monkey was jumping across this gap, her baby fell and hit the stump of a tree below, dying upon impact. The owners of the property were heartbroken and named this fallen monkey Bobby. We built a triangle of three rope bridges to connect this valuable tree to others on the property and the owners named the bridge where he fell, Bobby’s bridge.

How wildlife bridges help ecosystems

Bridges like these help wildlife and ecosystems in a variety of ways. They mitigate the effects of habitat fragmentation (when a habitat is divided into smaller, isolated pieces). When trees are removed to make way for properties and roads, parts of the habitat can become difficult, dangerous or impossible for wildlife to access. Tropical and temperate forest ecosystems are particularly vulnerable to the effects of habitat fragmentation.

Imagine if a deep canyon with a raging river at the bottom was created in front of your favorite place to get food. Although you might be motivated enough to hike down and up a canyon and brave the rapids in order to get to your favorite place, it may deter you enough that you may not return. Even if you do manage to reach your favorite spot, you will have risked your safety or exerted much more energy than you did before the obstacle was in place.

How rope bridges reduce the risk of extinction

Rope bridges not only allow for wildlife to safely and more easily access parts of their habitat, they also allow for gene flow – allowing individuals to reproduce with other individuals that they might not have been able to reach before. This allows for more genetic diversity, making the population more resilient to change and reducing the chance of the species becoming extinct.

In the video below, a male three-fingered sloth crossed a road using a rope bridge to reach a female calling to him on the other side (Video: Katra Laidlaw).


It takes a village

Thanks to the coordinated efforts of our generous donors, concerned community members and the SloCo team, many species are now able to safely navigate the habitat that we share with them. Thank you to Animalia, Jennifer, Adam and April for sponsoring Sloth Crossing bridges at Annanci Village and for helping to keep this sloth (and other wildlife) on the property safe.

Coexisting with wildlife can be a mutually beneficial experience. It requires just a bit of compromise from both sides. Willingness on our part to consider how we can modify our shared landscape and behavior in ways that are more accommodating to wildlife, and willingness on their part to adapt to the changes we have made for them.

The good news is that if it is possible for an incredibly habitual creature, like a sloth, to change her ways, it is certainly possible for us to adjust ours.




Would you like to sponsor your own Sloth Crossing?

Each “Sloth Crossing” bridge costs $200 to construct (in the most basic form: a single rope design without a camera trap). If you would like to help us to build more bridges (or personally sponsor your own sloth crossing), you can do so using the links below. If you sponsor a Sloth Crossing then we will install a personalized wooden plaque next to the bridge engraved with a name of your choice (this would make a fantastic gift for any sloth lover)! For gift sponsorships we can also email an information pack as well as photos and a GPS location of the fished bridge and plaque after installation on request (just send us an email after your donation)!

7 gifts that rainforests give to humanity

7 gifts that rainforests give to humanity

One of the things that I love most about the rainforest is its otherness – trees that stretch into the sky, hosting worlds of life that I may only glimpse from a distance. Entering the forest is a humbling experience, it reminds me of the vastness and diversity of life on this planet and how much there is yet to be seen.

Scientists estimate there to be 5-10 million species that live on this planet. We have only recorded 1.3 million of them. It is possible that 90% of the lifeforms on this Earth have yet to be noticed and appreciated by us.

Rainforest day

World Rainforest Day is an opportunity to do just that. To acknowledge and thank our rainforests for their many underappreciated contributions to our lives. Like most of the life on this planet, the work of rainforests is largely invisible.

So here are 7 things we can thank the rainforests for:

1) Rainforests produce and filter our freshwater.

The Amazon rainforest is responsible for 20% of our flowing freshwater. The trees in the Amazon rainforest have the incredible ability of creating their own rainfall, which is filtered by the forest and courses down the formidable Amazon River.

2) Rainforests are the origins of our medicine.

25 percent of all modern medicines used today have their origins in the rainforest, and 70 percent of plants with anti-cancer properties live in the Amazon. We have only studied one percent of the millions of species that live in tropical rainforests around the world. It is likely that that the cures to many of the diseases that threaten humanity live right under our noses. Even certain strains of fungi growing in sloth fur have demonstrated anti-cancer properties!

3) Rainforests support the daily well-being and health of over a billion people.

Approximately 25% of the world population (1.6 billion people) directly depend upon tropical rainforests for their daily needs. Vast amounts of people use medicinal plants on a regular basis to maintain their health around the world. 80 percent of African people use traditional herbal medicine. In India, 2,500 types of medicinal plants are used, supporting the lives of 400-500 million people who depend upon traditional medicine as their only option.

In addition to the variety of benefits that rainforests provide to our physical health, spending time in nature reduces the effects of stress, anxiety and depression. Having evolved in nature, having access to green spaces seems to be an essential element in promoting the health and well-being of humanity.

4) Rainforests are home to half of the world’s plant and animal species.

Although rainforests only cover 6% of the Earth’s surface they are home to half of the world’s plant and animal species. The biological diversity in rainforests is so intense that a tree in Peru was found to host up to 43 different species of ants and a single Peruvian rainforest was home to more bird species than those found in the entire United States.

5) Rainforests regulate our climate.

It is well known that trees, during the process of photosynthesis, will convert carbon dioxide (CO2) into sugar (glucose) and oxygen. Carbon dioxide is then stored in the tree’s wood. As it grows throughout its lifetime, a tree can absorb 50 pounds of carbon dioxide per year.

Although tropical forests remain an important carbon sink, the effects of climate change and damage caused by logging and farming is threatening the ability of even the mighty Amazon rainforest to absorb excess carbon.

6) Rainforests give us chocolate!

Indigenous people have used the rainforest as a source of sustenance and medicine for millennia. The Amazon rainforest, once considered largely untouched by humans, has been profoundly shaped by indigenous peoples. For 8,000 years, people selectively cultivated and domesticated rainforest species, such as the brazil nut and the cocoa bean, which continue to dominate the forest landscape to this day. It is thanks to the rainforests and the efforts of indigenous peoples’ that we are able to enjoy chocolate today!

7) Rainforests are where sloths live!

And last but certainly not least, rainforests are the home of sloths! Sloths, unlike most mammals, lack the ability to regulate their body temperatures and so they depend upon the steady, warm climate of the tropics. Their specialized muscles are designed for gripping and therefore they are perfectly designed to hang suspended in the canopy of rainforest trees.

Ancient ground sloths were vital seed disperses of avocados since they were one of the only mammals large enough to swallow avocados whole! It is thanks to the sloths that we can all enjoy avocado on toast today!

Giving back to rainforests

Protecting the world’s rainforests ensures that they can continue to bestow their many gifts for our planet. Preventing further encroachment into our wild spaces also reduces our risk for another pandemic while maintaining biodiversity, a powerful tool in our arsenal for climate change resiliency.

You can show the rainforests how much you appreciate them by sponsoring a tree for only $6! We plant a variety of rainforest tree species that are favoured by wild sloths, reconnecting forest fragments and restoring green spaces in urban communities.

The Real Cost of a Cheap Pineapple from Costa Rica

The Real Cost of a Cheap Pineapple from Costa Rica

In stores and supermarkets in North America and Europe, you can buy a pineapple for just a couple of dollars. But what is the real cost behind that cheap price? 

Today we commemorate sustainable gastronomy day by explaining how this popular and delicious fruit is impacting the lives of people, sloths, and the rainforest.

Pineapple: Del Monte GmbH - FRUIT LOGISTICA - Producto


Costa Rica exports more pineapples worldwide than any other country. Over 40% of the total exported pineapples come from Costa Rica, a value worth US$ 981 million. Pineapple production in Costa Rica has been criticized for years following public reports of public health problems linked to the contamination of soil and water by chemical substances used on farms.

Pineapple monocultures are causing serious negative impacts on the environment and on local communities. Even though small and independent farmers exist, the big transnational companies such as Dole or Del Monte maintain all of the power. They set the price to pay to small farmers, endorsing the already existing inequalities in some of the low-income areas of the countries.


Pineapples affect sloth populations

In Costa Rica, rescue centers and sanctuaries are receiving a high number of baby sloths with genetic abnormalities.  Most of them show similar deformities: missing or extra fingers/toes, partial or full albinism, misshapen limbs, or malformed ears. Most of these orphaned sloths don’t survive more than a few months. Some of them might reach adulthood but they won’t ever be able to be reintroduced into the wild.


baby sloth with deformity

The cause of these abnormalities is likely multifaceted, but two major factors stand out: habitat fragmentation and pesticides. All of the sloths displaying genetic abnormalities are found in areas with high levels of agriculture and rainforest disturbance. Sloths are not the only species to be affected by these problems.

In recent years, reports of mantled howler monkeys with yellow patches in their fur have increased. This is alarming scientists who believe that the monkeys are consuming too much sulfur from pesticides on the leaves they feed on. Most of these animals live in areas close to pineapple and banana plantations, where the pesticides contaminate the entire ecosystem. Both howler monkeys and sloths are folivorous, so they are probably consuming pesticides directly from the leaves they eat.

Did you know that Costa Rica uses more pesticides (per capita) than any other country in the world? On average Costa Rica uses 18.2 kilograms of pesticides per hectare of cropland. In comparison, a country like the United States uses close to 2.5 kilograms per hectare of cultivated land.

To properly understand  the cause behind the sloth deformities we launched a major study into the genetic health of wild sloth populations in 2016, taking data and hair samples from 100 wild-born sloths. By identifying the cause of the genetic abnormalities, we can develop the correct conservation strategies required to mitigate the problem. The results of this study will be published in the upcoming weeks, so stay tuned for the update!

Unethical labor conditions

The Rainforest Alliance, a scheme that provides certification to the pineapple producers of Costa Rica, is facing allegations of the illegal use of pesticides and labor exploitation of undocumented immigrants.

Rainforest Alliance says its certified plantations must adhere to certification rules, including “no mistreatment of workers”, and they are required to comply with strict audits and inspections.

The biggest problem is that the inspectors usually only have access to workers and facilities that are prepared by the pineapple plantations. The managers of the plantations often know in advance when the next inspections are coming, and the workers are interviewed in front of their bosses so they are not allowed to tell the truth about the conditions in the plantations.

Pesticides and pollution of pineapples

The use of pesticides is a well-known problem in Costa Rica. Studies conducted by the University of Costa Rica show the presence of Bromacil (a very dangerous pesticide) in rivers, wetlands and underground waters. Bromacil was banned in 2017, but there are reports of its illegal use nowadays.

El Milano in Siquirres is a community that has been forever damaged by the use of pesticides from neighboring pineapple plantations. In 2003 it was discovered that the primary source of drinking water for the entire community was heavily polluted with dangerous pesticides used in the farms.

It wasn’t until 2007 that the ministry of environment began to transport water to these communities with water-tank trucks. However, the people living there still have to use the polluted tap water whenever the water truck doesn’t arrive. This has led to several people being intoxicated and hospitalized due to pesticide consumption.

During the last 15 years the government of Costa Rica has had to invest 3 million dollars of tax-payer money to deliver clean water to El Milano. The real cost for the rest of these communities is still unknown.

Concerning expansions

According to satellite images provided by MOCUPP, pineapple plantations occupied 57,000 hectares of land in Costa Rica in 2016. However, the latest government report in 2019 indicates an alarming 300% increase over 3 years. 3,824 hectares of new pineapple plantations are invading protected areas, and 16,386 hectares are found in wetlands.

Not everything is bad news

At the moment there are 88 active lawsuits against pineapple companies in Costa Rica, and there is growing hope for the future that the government can provide sustainable solutions for the people and communities affected.

In 2016, a new 500 hectare pineapple plantation was proposed which would have been located less than five kilometres from the core of the important Térraba-Sierpe wetland ecosystem. Thankfully, the Ministry of Environment of Costa Rica (MINAE) suspended the project due to the imminent environmental impact. Even Carlos Alvarado (the president of Costa Rica) celebrated the decision on his social media:


Carlos Alvarado president of costa rica about pineapple project
“I welcome the decision of MINAE to suspend the environmental viability of a project for pineapple cultivation near the Térraba-Sierpe National Wetlands. This reaffirms our commitment to the environment, to Protected Wildlife Areas, and to the protection of archaeological heritage.”


Several organizations are also working hard to instigate change. The University of Costa Rica has spoken about the negative impacts of this agro-industry and they launched a call to action for politicians, academics, scientists and pineapple companies themselves to change the situation.

The university is also conducting scientific research and developing solutions to promote environmental-friendly farming practices. They also offer support to local communities and provide them with the necessary tools to fight the expansion of pineapple monocultures in their areas.


What can we do to help

What can we do as consumers? We must understand that we have the power. By choosing carefully what kind of products we buy, we can have a positive impact. Think twice before buying that $3 pineapple. Is there an alternative locally grown fruit that you could buy instead? If you need to buy a pineapple, try to find an organic option from an independent farmer and avoid the big monoculture companies that are responsible for so much rainforest destruction. This might be a bit more expensive, but it is nothing compared to the price being paid by the people and wildlife of Costa Rica.

Buying locally grown and organic produce supports small independent farmers and minimizes the greenhouse emissions caused by transporting food around the world. Although it is difficult to avoid this in a globalized world, by choosing where and how we buy these items we can all make an impact.

Many supermarkets simply don’t stock the more ethically and organically produced food. This can usually be changed just by asking! If you let them know that there is a demand for those items then they will find a way to provide them for you. Spend just a little time today contacting your local supermarket, and the knock-on effects will be felt around the world.

A decrease in demand for cheap tropical fruits is the best way to prevent monoculture plantations from encroaching further into the remaining rainforest.

Here at SloCo we are working hard to protect the sloth’s green rainforest home. Every month we grow thousands of ‘sloth-friendly’ trees in our SloCo forest nursery and we plant them in disturbed areas where habitat loss is threatening the survival of wild sloths. These trees not only help to fight climate change, but they also provide food and shelter for sloths!

How are sloths affected by desertification and drought?

How are sloths affected by desertification and drought?

As a child, upon hearing that there is an increase in “desertification” worldwide I probably would have been overjoyed, imagining molten brownies and ice cream sundaes overflowing with chocolate syrup. But desertification (with one “s” instead of two), unfortunately, does not consist of a surplus of desserts. It is our present and our future, and a much saltier one at that.

Desertification is not the “expansion” of deserts but rather the degradation of land in dry-land ecosystems due to over-exploitation and climate change. Dry-lands compose 1/3 of the world’s landmass and support the lives of 40 percent of the world’s population (2000 million people).

In concrete terms, desertification is caused by overgrazing, deforestation, over-harvesting vegetation for household use (such as burning), and agricultural practices that push fragile, arid land beyond its capacity.

The key to sustainable agriculture is creating systems that coexist and complement the natural ecosystems already in place. Agricultural practices with an emphasis on maintaining biodiversity are key to increasing food security and resilience in the face of climate change.


The link between dessert and desert

Although I may have misunderstood the true meaning of desertification as a child, that ice cream sundae I dreamed of, along with other animal products, are leading drivers of desertification.

One of the main causes of desertification is overgrazing. Overgrazing occurs when the plants in a pasture are not given enough time to recover and are therefore eaten down the roots, thus exposing the soil and making it more vulnerable to erosion and degradation.

80% of agricultural land is used for grazing and grain production to feed animals. In the Amazon rainforest, home to 10% of the world’s known biodiversity, cattle ranching accounts for 80% of current deforestation rates.

World Day to Combat Desertification and Drought

desertification and drought

The World Day to Combat Desertification and Drought (June 17) is a campaign to highlight the causes of desertification and drought and bring individuals together in combating them. Every single person has the ability to make a positive difference. And together we can make some incredible changes.


The Great Green Wall

One of the most inspiring collective efforts to combat desertification is the creation of a Great Green Wall across the southern edge of the Sahara Desert. The Great Green Wall is an African-led response to the increase in desertification and drought in of the poorest and most vulnerable areas on the planet.

Trees have a remarkable ability to cool down the environment. Similar to how we expel moisture with each breath we take, trees draw up water from the ground and release it through their leaves in a process called transpiration.

Rainforests, such as the Amazon, even have the ability to generate their own rainfall. Fundamentally collaborative, trees, and life that they support provide a whole host of benefits to humans and wildlife alike.

“Once complete (8,000 km), the Great Green Wall will be the largest living structure on the planet, 3 times the size of the Great Barrier Reef.”

“The Great Green Wall is an urgent symbol of hope in the face of the greatest challenges faced by mankind this century from climate change to food security, migration, and resource-driven conflict. It is a compelling example of man and nature working together to create a unique legacy – a new world wonder for the next generation.”

When the tropics go dry

The Caribbean side of Costa Rica is known for its rain. However, ever here, we have been experiencing water shortages. Some regions of the country received 75% less rainfall than expected leading the Costa Rican government to declare a state of emergency on July 23, 2019.

How are sloths affected by drought and desertification?

Drought, desertification, rising seas, and the expansion of industrial monoculture plantations are potent threats to sloths here in Costa Rica and in other places.

The tropical rainforest ecosystem where sloths live is drying up. The regular downpours that keep the rainforest lush and green have become irregular and short. Rivers that normally flow year-round have become seasonal streams, and temperatures are gradually increasing and becoming more extreme.

Tropical species are not prepared for these new, erratic weather patterns. They have evolved for millions of years in a relatively stable climatic environment and are therefore very vulnerable to even small changes in temperature and weather.

Sloths are unlike many other mammals because they are unable to regulate their own body temperature. This means that everything they do is dependent upon the weather. If it gets too cold outside, sloths can easily get hypothermia. If it gets too hot, they can overheat. Of particular concern right now in Costa Rica is the lack of rainfall. Sloths are being admitted into rescue centers all over South and Central America suffering from dehydration, and we are seeing a big increase in the number of sloths drinking from rivers.

What can be done?

It can be easy to feel hopeless and overwhelmed – but we must never underestimate the power that we all have in our day-to-day actions (check out this list of 7 simple ways that you can help sloths today from the comfort of your own home).

The Great Green Wall is a shining example of the change that can be accomplished on a local, regional and continental scale.

Coming together to enact change is necessary to redirect our resources in a way that will sustain many future generations of life on this planet. Starting a clothes exchange among your friends, reducing your consumption of animal products and lobbying your local politicians to redirect food subsidies to sustainable agriculture are a few powerful examples of ways that we can all help to mitigate the effects of climate change.

Here at SloCo we are working hard to protect the sloth’s green rainforest home. Every month we grow thousands of ‘sloth-friendly’ trees in our SloCo forest nursery and we plant them in disturbed areas where habitat loss is threatening the survival of wild sloths. These trees not only help to fight climate change, but they also provide food and shelter for sloths!

Helping Sloths By Helping Dogs

Saving sloths by sterilizing dogs

What do these two have in common?

Cute baby sloth and dog puppy


You might find them both featured in baby animal calendars or filling the feeds of animal aficionados. But the lives of these two animals are entangled not just because of their comparable cuteness.

When their bite is worse than their bark

Over 180 different species of wild animals are now threatened by dogs and at least 11 are now extinct because of  our canine companions. After cats and rats, domestic dogs have become the third-most-damaging mammals – and yet this fact has received almost no media attention. Domestic dogs include feral and free-ranging animals, as well as those that are cared for by humans as pets.

Predation is the biggest threat posed by domestic dogs to wildlife, followed by the transmission of diseases, competition, and hybridization. The regions most affected by these issues are South-East Asia, Central America, the Caribbean, South America, Asia, and Australia.

A big problem for sloths

Dog attacks are now the second leading cause of death to sloths in Costa Rica. Rescue centers receive 2 to 3 wild animals per week that have been injured by dogs or cats.

The chances of a sloth encountering a dog are high due to the sheer number of dogs roaming around and the fact that human development is breaking up the sloths habitat. Since sloths can’t jump, they often resort to crawling on the ground to travel between trees in urban areas. A sloth on the ground has no way to defend itself against a dog. If the sloth somehow survives the initial attack, secondary infections from the bite wounds often prove to be fatal.


Sloths are vulnerable to a dog attack when they are on the ground

Myths about sterilization make things harder

Incorrect beliefs about the castration and sterilization of animals, coupled with irresponsible ownership and abandonment, has lead to a large number of stray and feral dogs roaming the streets.

This is a bad scenario as a single female can produce 4 to 5 puppies per litter, twice a year.  A lot of people think that all dogs should have puppies because “it makes them happy” or “if they don’t experience motherhood they’ll be sad”. Other pet owners don’t want to sterilize their male dogs because this might “affect the dog’s virility”, despite the proven benefits of neutering them.

Fun fact: Did you know a method to neuter dogs without surgery was recently developed?

Oh My Dog!

The ‘Oh My Dog’ project is a new initiative that we launched in 2019 which aims to reduce the number of dog attacks on wildlife in Costa Rica. This project has a three-pronged approach:

  1. Reduce the need for arboreal animals to travel on the ground. We achieve this by planting trees in target areas and installing wildlife canopy bridges to connect habitat fragments. We work with private property owners who’s dogs have been known to attack wildlife in the garden, as well as with the government of Costa Rica to make urban areas safer for sloths.
  2. Reduce the number of dogs roaming around unsupervised. We have partnered with local rescue organisations (Puerto Viejo Dogs and Clinica veterinaria Drs Arroyo & Solano) to fund the sterilization of all stray dogs in the South Caribbean region of Costa Rica.
  3. Community awareness to encourage responsible dog ownership. We have developed a set of guidelines that community members can follow to reduce the chances of pet dogs attacking wildlife.

oh my dog

One billion dogs worldwide

In a world where humans and their pets reach every corner of the planet, achieving harmonious coexistence with nature is a fundamental task for conservation.

So, if you love sloths and you love dogs, please consider helping us with this campaign. It’s a win-win for dogs and sloths!

Social distancing: learning from sloths

It is an unnerving time. The world watches with baited breath as the coronavirus outbreak continues to spread and social distancing becomes the norm. Doubts about the stability of the future and concerns for our loved ones press on our mind making it difficult to think clearly.

To get the latest updates on the COVID-19 Situation:


As of March 18th, the first confirmed case of coronavirus was reported in Limon, an hour’s drive from where we are based in Puerto Viejo, Talamanca. We are entering a time that so many have already been experiencing, with lock-downs and uncertainty looming on the horizon.

Social distancing is difficult for a social species. Research has shown that strong social ties contribute to our overall health. The challenge in this time is to remain connected, while reducing the opportunities for the virus to pass from person to person.

As many are aware, COVID-19 or SARS-CoV-2, is a “new” type of coronavirus, the seventh one that we have come into contact with. The virus is a zoonotic disease or zoonoses, meaning that it passes from animals (vertebrate) to people.

SARS-CoV-2 was likely transmitted from wildlife to people at the Huanan wild animal market in Wuhan, China before making its way around the globe. According to a recent report published in Nature, although the exact animal source of SARS-CoV-2 remains uncertain, it highly resembles viruses found in bats and pangolins, meaning it likely mutated as a product of natural selection.


A pangolin being trafficked in Kuala Lumpur


According to the World Health Organization, “Over 30 new human pathogens have been detected in the last three decades, 75% of which have originated in animals.” Zoonoses have and continue to pose a huge threat. The SARS epidemic in 2002 originated from small mammals, MERS had its reservoir in dromedary camels, HIV from primates , and Ebola was likely transmitted from fruit bats, porcupines and primates.

In light of this pandemic, it has become clear that in addition to “social distancing” we all should be practicing “wildlife distancing.”

So what does wildlife distancing look like?

The appropriate distance between you and a wild animal is at least 2 meters (6 feet)


Fortunately, most wildlife (like pangolins and bats) pose no threat to human health when given the proper space in the wild. In fact, when left alone, they can actually help to reduce other pest populations. Bats are known for their ability to eat mosquitoes helping to reduce the population of the world’s deadliest animal to humans.

Wildlife distancing means preventing direct contact between wild animals and people. This can take the form of turning down wildlife selfies or carefully scrutinizing products before buying them. Wildlife distancing, in addition to social distancing, is necessary to prevent the spread of COVID-19 and the emergence of future epidemics.



However, wildlife distancing goes beyond simply avoiding wildlife products and preventing interactions between people and wild animals. Any actions that help to slow or prevent the encroachment on the world’s last wild spaces not only reduces our risk for another pandemic, but also protects biodiversity, one of our greatest allies in the face of many global threats.


Still from Jungles episode of the Emmy ® Award winning series, Our Planet:


Although protecting biodiversity may seem counter intuitive given the current zoonoses wreaking havoc on the world, diverse ecosystems are key to resiliency. Our ecosystems provide us with a variety of vital services, air and water purification, the prevention of soil erosion, carbon storage, and food security. Tropical rainforests, like the Amazon, even have the incredible ability of generating its own rainfall.

Moreover, tropical rainforests have been the source of many life-saving medicines. For example, Quinine, discovered by the Quechua of Peru and Bolivia, was the first effective treatment against malaria. Vincristine and Vinblastine, come from the Madagascar Periwinkle, a flower native to the island, and are used to treat different types of cancer.


Quinine bark and Madagascar Periwinkle flower


So if you are feeling helpless in this frightening time, consider how you can (from a safe distance) contribute to protecting the world’s biodiversity and promote wildlife distancing. The more we can spread awareness while minimizing the transmission of disease, and stay connected while remaining safe, the more likely we can minimize the impacts of this global pandemic and prevent future outbreaks.

Sloths are natural social distancers, preferring to remain isolated and camouflaged to reduce the chance of predation. Here at SloCo, we are taking a page from the sloth’s book, practicing distancing to keep us all safe.


We hope the same for you and your loved ones.
