- Nutritious meals for orphaned and injured sloths
- Urgent medical care and long-term rehabilitation
- Reforestation and safe passageways like our Sloth Speedways
- Research and education programs that help protect sloths and their fragile ecosystems
Whether it’s $5 to feed a sloth, $35 to support veterinary care, or a monthly gift that sustains our life-saving programs, every dollar counts!
Signature Sloth Conservation Programs

The Tree Nursery
We have a Tree Nursery full of baby trees of various species that sloths and other wildlife need for survival. The only way to combat habitat degradation is to reforest. Help us plant more trees through our "Adopt-A-Tree" donation program!

The Sloth Institute founded "Sloth School," a series of stages for sloths undergoing rescue and rehabilitation. Our human educational programs aim to educate all ages and nationalities. People around the world can affect sloths in the wild.

Why I support The Sloth Institute:
I support many rescue centers and I love to hear how much everyone loves and appreciates the work that is being done at The Sloth Institute. I am always ultimately amazed at how welcoming and open hearted they are with all of their sloth rescues & I can say that they are the best at what they do which is keeping sloths safe and in the wild.

VOLUNTEERThe Sloth Institute gives orphaned and injured sloths a chance to recover and return to the rainforest to live wild and free...I cannot think of a more noble, inspirational purpose! Visiting them and seeing the dedicated staff in action is incredible. I wish I could live there and work alongside them every day!

Kerstin Johnson
VOLUNTEER/DONORI can’t speak highly enough of the amazing team at The Sloth Institute (TSI) & their outstanding work in sloth conservation. Born out of a genuine desire to help wildlife & stop animal cruelty, Sam Trull & her crew constantly strive to make the world a better place - one sloth rescue at a time. They believe that every sloth is born to be wild and this is evident in everything they do and stand for.

Vivian Nguyen
VOLUNTEER/DONORThe Sloth Institute inspired us to take our interest in sloths, and grow it into a passion for their conservation. TSI has shown us, through their stories of rehabilitation, that every sloth deserves to be wild and free in the trees. They also educate on how humans have an impact on these fluffy friends, and how we all can minimize that impact.
