Adopt an orphaned orangutan
Orangutans are on the brink of extinction. Help provide the care and rehabilitation
they need to return to the wild.
The Problem
There are numerous threats to the viability of the remaining wild orangutan population in Indonesia and Malaysia. The primary threat is the loss of habitat with up to 80% of suitable forest in Indonesia and Malaysia having been lost in the past 20 years. Other threats, which often go hand-in-hand with the destruction of the rainforest, are the illegal pet trade and poaching.

Do you remember when Baimah arrived at our centre in September 2022?
Before her rescue, a resident had kept her as a pet for 1.5 years; she was obese and, therefore, struggled to breathe through her nose.
Fast forward to today—look at this happy, curious, and easily breathing #orangutan in the video!
However, the little female still has a long rehabilitation journey ahead of her.
Will you sponsor Baimah and help her on her way to #OrangutanFreedom?

VOLUNTEER NEEDED for around-the-clock care of an #orphan baby #sunbear cub born around 1 February 2025.
The #volunteer is expected to focus entirely on hand-rearing the #bearcub and will be working with the help of the local staff under the supervision of the Sun Bear Coordinator and Patrick Rouxel, BOS Foundation's Sun Bear Consultant.
The cub needs to be out in the forest every day so that she can spend as much time as possible exploring and playing, but she also needs her milk at night every few hours.
The volunteer will work at the BOS Foundation's sanctuary in Samboja Lestari, East Ka#indonesia#Indonesia.
Room and board are provided, but the volunteer is expected to cover their travel, visa, insurance and medical check-up expenses.
We need someone#ASAPegin #asap for a minimum duration of 6 months, but longer if possible.
