The dominant uncultivated vegetation is ipil-ipil ("Leucaena leucocephala"). A similar enzyme, mimosinase, is produced by "Leucaena leucocephala". Subabul (leucaena leucocephala) has been planted in patches in some parts of the sanctuary. Some species (namely "Leucaena leucocephala") have edible fruits (as unripe) and seeds. The dominant upland vegetation is ipil-ipil ("Leucaena leucocephala"), which covered most of the slopes.
