ABSTRACTComposition and Structures Community Lowland Fires in Gunung Masigit and Preliminary Study of Natural Regeneration Forest Fire Gunung Masigit, G. Gede-Pangrango National ParkGunung Gede Pangrango National Park, is one of the Long-term Ecological Research Site in Indonesia. In the late 1997, the fires have burnt and destroyed nearly 300 ha forest in this park . Of nine location of hot spots recognized G.Masigit was the largest burnt area with the tot& of 250 ha . Undergrowth vegetation got the most severe impacts. Almost undergrowth vegetation in various location in study site were totally burnt. However, with in three months following burning new seedlings such as Omalanthus populneus, Macaranga tanarius , Trema orientalis appeared in the forest floor.°Abdulhadi et al. (1999) reported that those species were found as the component of seed bank in a permanent plot of this forest. Thus, it is believed that those seedlings might be recruited from seed bank or seed rain.The objective of the research is to find out the composition and structure of undergrowth forest a community after forest fire in Gunung Masigit, G. Gede-Pangrango National Park.Data collection were carried out between April and September 1999 at three areas, i.e. upper slope, lower slope, ridge. Four transects of 275 m were established within each site; each two transects established in burnt and unburnt forest. A long the each 275 m transect 25 plots of l x1 m were established with the interval of 10 m.A total of 43 species belong to 39 genera and 35 families were recorded within 150 plots of unburnt sites. The dominant species of the unburnt sites were Dipteris conjugata, Blechnum fnlaysonianum, Impatiens javensis, Urena lobalata, Pteris sp, Elatostemma sp, Smilax zeylanica, Schima wallichii, Phaius sp, Vitis adnanta, Dendrochy1/um sp, Cyperus sp.Based on their important value indices (I V I) the plant communities in lower and upper slopes were called Dipteris conjugata community, while in ridge site was an association of D_conjugata and Blechnum fin/aysonianum. The composition of undergrowth forest community observed during this study clearly indicated that G. Masigit has experienced some kind of disturbance before the fire in the late 1997.Field water capacities of the dominant plants of the undergrowth forest were about 30 %. It is believed that this condition makes the forest is under high risk of fires.The species richness of born sites was higher than in unburnt sites due to occurrence of the secondary species such as Melastoma balatrichum and Omalanthus populneus, that were not found in the unburnt site. There were 38 species found on the ridge, as the richest site, followed by upper slope 33 species , and the lower slope 21 species. Based on the life form, the undergrowth species in burning area can be classified to 18 species of trees, 6 species of shrubs, 9 species of lianas, 15 species of herbs, and 5 species of ferns.The undergrowth forest community in burnt sites was dominated by herbs and ferns indicated that the community was still in an early succession. The LVI of plant communities in burnt site showed that the lower slope was the association of Pteris sp-Flatostemma sp., the upper slope was a community of Cyperus sp, and the ridge was the association of Cyperus sp-Pteris sp.

"The Gunung Gede - Pangrango National Park is known as a reserve for protecting plant and animal diversity, and has been listed as a biosphere reserve by The United Nation for Educational, Scientific and Cultural Organization (UNESCO). The Floristic composition in this park is very diverse ranging from lowland and mountain forests to sub-alpine vegetation. The forest in the national park does not always have a closed canopy as gaps have been created by both natural forces such as death of trees or windblows and by human activities. This study was designed to examine: 1) species richness and forest structure at the sapling level; 2) forest regeneration; and 3) potential uses of saplings and seedlings. The study area was located at the forest at Bodogol at the altitude of 800 m above sea level (asl). Saplings were recorded in 25 plots of 10 m x 10 m of each. The study site was located along the hill path. A sapling species inventory was conducted in one-hectare plot, which was divided into 25 subplots of 10 m x 10 m each, where enumeration, measurement of diameter and identification of each sapling were undertaken. Enumeration and identification of shrubs, tree seedlings, herbs and ferns were made in 25 subsubplots of 1 m x 1 m each. The results indicated that the sapling species richness is remarkably high. The numbers of sapling (< 10 cm diameter at breast height) recorded in 25 plots with total area of 2500 m was 1516, which belong to 83 species and 34 families with total basal area of 0.124 m2. The highest density of 356 saplings per hectare were recorded in Rubiaceae, with two leading spesies Urophyllum arboreum and Paederia foetida. Uropyllum arboreum was recorded as the most frequent sapling across 18 subplots of the total 25 subplots. Lithocarpus elegans, Acer niveum, Villebrunea rubescens, Sterculia oblongata, and Cryptocarya tomentosa were recorded as having the highest basal areas. Five species were recorded with biggest Importance Value Indexes (INP); Urophyllum arboreum (INP=23.75%), Paederia foetida (INP=13.10%), Villebrunea rubescens (INP=8.94%), Antidesma sp (INP=8.51%), and Persea excelsa (INP=7.88%). Above ground vegetation showed remarkable high species richness with total count 68 species, belonging to 44 families representing 224 individuals recorded in 25 subsubplots with total area of 25 m2. The highest frequency was recorded in Diospyros frutescens, which recorded in 7 subsubplots. Schismatoglottis calyptrata from Araceae family was recorded as the most prominent species. Twenty five subplots with a total area of 2500 m2 at Bedogol in the national park, 126 species have been identified of having potential uses for traditional medicines, building material, food sources, fire wood, handy craft, and ornamental plants."

ABSTRACTAims of this study is to investigate the effect of elevation on diversity of Insectivores and Rodents in Gunung Tujuh, Kerinci Seblat National Park. Surveys were conducted at 1500 masl and 2000 masl elevation by employing removal sampling technique from 17 to 26 January 2011. Specimens were collected using pitfall trap and snap trap arranged in a 100 m line transect. These nine days survey covering trapping effort of 1677 trapnight, and resulting in 6,8% trap succes rate. Ten species were recorded at 1500 masl elevation, slightly higher compared to only nine species recorded at 2000 masl elevation. Shannon-Wienner index shows a decreasing pattern with increasing elevation. In addition, Sørensen similarity index (CCs = 0,42) shows a differences in species composition from both locations. The difference might be due to different habitat types at both locations."
