Species of Pinus merkusii Jungh et de Vries of Kerinci is a unique variety, because this species grows naturally in southernKerinci Mountain. Objectives of this research were to identify growth distribution of P. merkusii Kerinci variety based on field condition and to determine important physically factors for growth of P. merkusii Kerinci variety. This research was conducted in montane rain forest of Bukit Tapan, Kerinci Seblat national park region for two months (April-May 1996). This research used multiply plot sampling with rectangular form (20 m x 20 m) in 24 the research sampling plots. Soil samples were taken from each plot for soil c h d s t i c analysis. Data was analyzed by vegetation analysis, ordination, and multiple regression linear by stepwise procedure to identify mostinfluence's physical factors. Research was found 47 trees species classified within 39 genus and 25 family. The 24 permanent plots wen dominated by P. merkusii (IVI = 115.33%). Number of P. merkusii in each permanent plot among 1-13 trees. Range of basal area of pines between 0.66 m2ha and 39.08 m21ha whereas non-pines among 4.06 m2ha and 13.88 m h a . The result of research showed that P.merkusii Kerinci variety grow well in Litosol soil, with sandy clay texture, with proportion of sand : dust : clay are 14 : 5 : 1 or I5 : 4 : 1, 53.21-56.48% of porosity and 1.14-1.24 g/cc of bulk density.

Mangrove ecosystem have various important roles as habitat for marine and terrestrial species. However, the ecosystem has recently faced anthropogenic threats delivered by the expansion of aquaculture pond. Study of mangrove diversity was conducted in Production FMU Bulungan Unit VIII, North Kalimantan. The study was aimed to analyze species diversity in the FMU Bulungan Unit VIII and determine community perception on existing mangrove condition. Vegetation analysis was applied to quantify mangrove community in two sampling locations, Salimbatu and Liagu, within 26 quadratic plots (10mx10m). As many as 63 respondents were interviewed to analyze communities’ perception. As the result, 10 species were identified species and one unidentified species recorded during the survey. Rhizophoraceae was dominated the species composition in sampling area. Rhizophora mucronata had the highest Importance Value Index in tree and seedling stage while Rhizophora apiculata was dominant in sapling stage. On the other hand, Bruguiera parviflora was recorded on each growth stages in all sampling plots. Species diversity index (H’) of mangrove vegetation in the FMU was found at 1,68 with species richness index value 1,58. This diversity index considered as moderate diverse since only few vegetation species are able to live in the mangal. The perpendicular structure of mangrove in the FMU formed an inverse J-shape which showed normal growth of uneven-age forest stand. The interview result implied that more than 50% of the respondent considered that mangrove condition in their village area has been disturbed. Therefore mangrove management with local community involvement is neccessarily required to improve the mangrove performance. Keywords: communities perception, habitat, mangrove, species diversity

Forest fires and land conversion to oil palm plantations are one of the major threats that caused dangerous impacts on the existence of peatlands in Indonesia. Rehabilitation by plant type enrichment method is an effort that can be developed to restore the ecological and hydrological functions of degraded peatlands. This study aimed to analyze biophysical conditions (soil characteristics), analyze the growth response of plant species against the combination of planting types; analyze the choice of planting combinations that are in accordance with the physical conditions of the field and the needs of local communities. This study was designed by varying the diversity of tree species or combination of planting. The research plot consists of three size area (5m x 5m, 10m x 10m, and 20m x 20m). The species that used in this study consists of Shorea balangeran, Durio zibethinus, Archidendron pauciflorum, Parkia speciosa, Coffea liberica and Areca pinanga. The results showed that the research plot has soil characteristic from mesotropic fertility categories (moderate fertility) to eutophic (fertile), while the pH between 3.2 – 3.5 (very acidic). The growth of plant species at the age of five months has growth rate differentiation both height and diameter in each combination of planting. The height growth of Shorea balangeran species the highest which average of 35.16 cm while the diameter growth of Areca pinanga is 8.13 mm. The best combination of planting is a combination of six species wich consists Shorea balangeran, Durio zibethinus, Archidendron pauciflorum, Parkia speciosa, Coffea liberica and Areca pinanga. Keywords: enrichment planting, growth, rehabilitation, peatlands

The characteristics of tropical peatlands are still able to form a high diversity of plants. Conversion of tropical peatlands affects the composition of plants. The aim of this study was to find out effect of land use changes to the composition and diversity of plants in the Peat Hydrological Unit (PHU) Mendahara - Batanghari River. The research was conducted in three land use categories, namely secondary forest, coffee plantation, and oil palm plantation (subdivided into oil palm plantation 1 and oil palm plantation 2). In each study location, sample lane 20 m x 200 m were made. Overall, we found 77 species of plants. The results showed number of plant species decreased due to changes of land use. There are 51 - 53 species of plants in secondary forest areas (out of a total of 58 species) that are not found in oil palm and coffee plantations areas. Differences in composition were also shown in the low value of community similarity (<50%). In the oil palm and coffee plantation areas, plant communities tend to be dominated by pioneer plants such as Melicope lunu-ankenda, Coffea liberica, Macaranga triloba, and Melastoma malabathricum. Secondary forest was dominated by plants species that characterize peatlands such as Tetramerista glabra, Parastemon urophyllus, Knema percoriacea, Litsea costalis var. nidularis and Madhuca motleyana. Changes in land use also reduce the level of diversity (H 'and R) at various levels of growth. Whereas in the oil palm and coffee plantation areas tend to form uniform stands (indicated through index E which describes the abundance distribution in community and index C which describes the dominance of species). Generally, the distribution pattern of plants is clumped. Uniform distribution was found in K. percoriacea and L. costalis var. nidularis. Keywords: land use changes, peatland characteristics, plant composition, plant diversity
