Rawa Danau Nature Resetre has treen identified as an important natural site because it represe,rls thelasl of fresh waler and pal swamp forest ecosysrems remains in Java lsland. For years, the naturalecosyslems in lhis unique area lave been significantly affected by illegrl cullivation exlension thalllrealens lhe sustainability of the ecosystems. The aims of lhis paler dre lo identify land cover changedynamics bel$,een 1994 and 2000, focusing on lhe exlenl of illegdl cultivation in the reserve area. and
