We have 2 kind of islands :

Pre release island. This is the last point before a rehab orangutan being release back to wild

Sanctuary island for un-releaseable orangutan

An island is much better option than any most luxury cage or enclosure. This is the best option for unreleasable orangutans. We name this kind of sanctuary as #OrangutanIsland.
The island is located in the river. We manage the island together with local communities. Theyhelp us supply food, saveguard the island, and also guiding visitors. That way, the local economy will be developed by supporting conservation efforts. Once conservation efforts bring direct benefit to communities, then communities will support and protect the orangutans
