ABSTRACTThe changed in 1995 ? 1998 when a programme of massive Peat Swamp Forest (PSF) conversion, the socalled Mega Rice Project (MRP) in Central Kalimantan was initiated to develop rice field has been impact bothdeforestation and forest degradation. The aim of this research is to classify forest degradation rates of PSFaccurately using multi-stage remote sensing methods through (1) Forest Canopy Density model (FCD) LANDSAT 5TM image acquired 2010 and supported by aerial photos interpretation, (2) inventoryineach forest cluster weredetermined by purposive sampling using 5 plotswith size of 20m x 20m.The results showed that there wasasignificant correlation(r)=0.82 between FCD and Canopy Area Index (CAI). Significant correlation was also shownbetween CAI and stand density, dominance andfrequency respectively with the value of r = 0.974; r = 0.937 and r =0.871. Based on these correlation, predicted that PSF on the researcharea has been changed become deforestation53.68%, very high degradation 3.37%, moderate high degradation 11.21%, middle degradation 15.30%, moderatelow degradation 15,45% and low degradation 0.99%.The conclusion thatthe PSF ecosystem of MRP largely hasbeen transformed intodegradation and deforetation areas.Keywords: Peat swamp forest, remote sensing, ecology, degradation and deforestation.

ABSTRACTRiparian vegetation is easily distracted natural resource due to mankind activities. This study attempts toexamine the species composition, the stand structure, and the species diversity of riparian vegetation on PagerRiver, Rakumpit district, Palangka Raya. The vegetation data were collected through path combination method withgridline. We find out that the plant diversity of all types of growth is 28 species with 16 families. The number ofspecies on station I (upstream) are 13 species with 7 families, while the species having the highest INP is GalamTikus (Syzygium zeylanicum (L) DC). There are 19 species with 11 families on station II (middle) in which Resak(Vatica rassak) has the highest INP. Meanwhile on station III, there are recorded 16 species with 11 families wherethe most dominating species is Balawan (Tristaniopsis stellata Ridl.). The spread of tree diameter of riparianvegetation on Pager river (upstream, middle, downstream) suggests the pattern of reversed "J". Of the upstreamriparian, the species diversity values of all types of growth sit on the low category. Of the middle and downstreamriparian, the diversity values are both low at the seedling and sapling level.Meanwhile, those values are in mediumcategories at the pole and tree level. The species richness generally corresponds to the low category whereas thespecies evenness corresponds to the high category.Keywords: Diversity index, species composition, structure, riparian vegetation
