ABSTRACT
The aims of this study were to determine the composition, structure, and growth of endemic
species of peat swamps in the areas of ex-burned, burned border, and non-burning areas; also
measured the growth of endemic seedlings in the burned area at the Orangutan Research Station
of Tuanan (SPOT); and also to know the type of orangutans feed tree in the Orangutan Research
Station of Tuanan (SPOT). The location of this research is conducted in the area of Research
Station of Orangutan Tuanan of Central Kalimantan Province on the ex-burned field, with the
research period was 4 (four) months. The results showed that vegetation composition and
structure were dominated by plant species of Tutup Kabali (Diospyros pseudo-malabarica),
Kayu Randa (Gardenia cf. Pterocalyx), Kumpang Daun Perak (Gymnacranthera sp.), Manggis
Hutan Daun Besar(Garcinia cf. Beccarii, Keput Bajuku (Stemonurus scorpioides, Tarantang
(Campnosperma coriaceum), Karandau (Neoscortechinia sp.) dan Rambangun (Acronychia
pedunculata).Based on the value of species diversity in the transect of SG and HR was lowmoderate and in transect SA and IS diversity was moderate-high. The fastest growth in SG
transect, where the average growth rate was 12.8 cm and 0.1 cm in diameter; whereas in the IS
transect the growth was low, where the average growth rate was 1.5 cm and diameter 0.04 cm.
Several dominant species of Orangutan feed plants in the research plots are Tutup Kabali
(Diospyros pseudo-malabarica), Jelutung (Dyera polyphylla), Rambangun (Acronychia
pedunculata), Bajuku Keput (Stemonurus scorpioides), Manggis Hutan Daun Besar (Garcinia cf.
Beccari), Tarantang (Campnosperma coriaceum).
