Population status of endemic tree kokoleceran (Vatica bantamensis) in Ujung Kulon National Park, Indonesia

A critically endangered tree species, kokoleceran (Vatica bantamensis), found exclusively in Ujung Kulon National Park (UKNP), Indonesia, faces severe population decline due to habitat loss and invasive species. Research using adaptive cluster sampling identified 280 individuals concentrated in Mount Payung, with only 20% mature, indicating an inverse-J-shaped population structure. The species' area of occupancy is estimated at 8 km², highlighting its extreme vulnerability. The invasive langkap palm (Arenga obtusifolia) poses the greatest threat, necessitating urgent conservation intervention to prevent further decline and potential extinction.
