Published focus
SOCP explains that Yayasan Ekosistem Lestari implements its Indonesian activities. Its landscapes include Leuser, Batang Toru, and reintroduction work in Jantho.
Understanding its work
The programme connects orangutan rehabilitation with habitat protection and population monitoring. Symbolic support for an orangutan does not mean ownership or permission to approach wildlife.
Before you contact
