Habitat fragmentation effect on the characteristics of orangutan nest tree selection

Abstract Orangutans are an endemic to Indonesia and Malaysia with almost extinct critically endangered status only found on the islands of Sumatra Kalimantan/Borneo. Orangutan extinction is mainly threat by habitat loss fragmentation as well low reproduction rates. Habitat fragmentation, along loss, should be clearly considered when assessing implications landscape change for population extinctions. Environmental changes force species immediately adapt both behaviourally physiologically. Forest structure affects adaptability nesting behaviour orangutans. One steps prevent orangutan increasing connectivity through corridors reducing landscapes stopping lost.
