TREE SPECIES DIVERSITY AND ETHNOBOTANY OF DEGRADED PEAT SWAMP FOREST IN CENTRAL KALIMANTAN

KALIMA, T., SUHARTI, S., SUMARHANI & TRETHOWAN, L. A. 2020. Tree species diversity and ethnobotany of degraded peat swamp forest in Central Kalimantan. Reinwardtia 19(1): 27‒54. ‒‒ Most peat swamp forest has been degraded. This has resulted in decline of its biodiversity. The objective of this study was to identify the composition, diversity, and plants used by local people in Bagantung swamp forest. The study was conducted on degraded peat swamp forest area in Bagantung, Mantangai Sub-District, Kapuas District, Central Kalimantan Province. The Shannon-Wiener (H’) and the Importance Value (IV) indices were used for analyzing the species diversity and the species importance across a number of forest plots. Useful tree species were identified by interviewing local villagers. There were 2,562 individual plants in 32 plots (each plot 20 m × 20 m). We identified 100 tree species and 16 non-tree species, from 74 genera, and 46 families. Myrtaceae, Sapotaceae, Ebenaceae, Dipterocarpaceae and Clusiaceae were the most dominant families. Large tree (H’=1.46) and small tree diversity was similar (H’=1.75). In both small and large tree size classes Calophyllum nodusum was the most dominant species. There were 16 tree species and two non-tree species used by local people for house and boat construction, furniture, handicrafts, medicine, and insect repellent.

Ismail MH, Fuad MFA, Zaki PH, Jemali NJN. 2017. Analysis of importance value index of unlogged and logged peat swamp forest in Nenasi Forest Reserve, Peninsular Malaysia. Bonorowo Wetlands 1: 74-78. Peat swamp forests are highly significant globally, both for their diverse and threatened species and as a representative of unique wetland ecosystems. Apart from its critical role in providing habitat for wildlife, the tropical peat swamp forest also acts as a gene bank that harbors potentially useful varieties of plant species. The composition of trees of the peat swamp forest in Nenasi Pahang State, Peninsular Malaysia were investigated especially in un-logged and logged over forests. The objectives of this study are two folds; (i) to identify and compare the dominant tree species in the two types of forests and (ii) to calculate the importance value index (IVI) of the vegetation in the study areas. Two plots of 50 m by 20 m were established in different forest type. At each site this quadrate was in turned subdivided using a 25 m by 20 m, and 5 m by 5 m, respectively. The results showed that the unlogged peat swamp forest is higher in tree species compared to logged peat swamp forest. There were 10 species distributed among 9 families in the unlogged forest and 7 species in 7 families in the logged forest. The most dominant species identified in unlogged peat swamp forest were Litsea sp., Syzygium sp. and Santiria laevigata. The IVI for these species were 71.21, 51.13 and 42.49. In logged peat swamp forest the dominant species are Shorea platycarpa, followed by Pometia pinnata, and Xylopia fusca. The IVI of these species were 87.38, 52.66 and 47.55, respectively. The study concludes that in the logged peat swamp forests about 40 percent of the tree composition has declined compared to unlogged peat swamp forest.

Forests are natural resources that provide double benefits, direct and indirect benefits. The direct benefit of forest is as a source of various types of goods, such as woods, saps, barks, leaves, roots, fruits, and flowers that can be used directly by humans or become raw materials for various industries. The special-purpose forest of Tumbang Nusa is a secondary peat swamp forest. Peat swamp forest is a forest formation quite widespread in Indonesia. The term arises because swamp forest and peat forest are basically always adjacent and often do not have clear boundaries that are so-called peat swamp forests. The purpose of this study was to find out the structure and species composition (species dominance, species diversity, species richness and species evenness) of secondary peat swamp forest vegetation in special-purpose forest of Tumbang Nusa, Jabiren Raya Subdistrict, Central Kalimantan Province. The results of the study showed that the vegetation structure by diameter classes was dominated by the vegetation with small diameter (0-9 cm) and by height classes was dominated by the vegetation with low height-class (0-5 m). The diversity of vegetation in the study plots showed that there were 42 species of vegetation consisting of 24 families, and the most common species found were the family of Lauraceae (5 species), Dipterocarpaceae (4 species), Myristicaceae, Myrtaceae and Guttiferae (3 species), Podocarpaceae, Apocynaceae, Ebenaceae, Moraceae and Annonaceae (2 species), and a few other family (one species of each). The species diversity at seedling and sapling stages was moderate (H' ≥ 2 and < 3) while the diversity at pole and tree stages was low (H' < 2). The values of species richness index at seedling, sapling and pole stages were moderate (R = 3.5 - 5.0) while at the tree stage was relatively low (R > 3.5). The species evenness index at seedling and sapling stages was high (E > 0.6) while at the pole and tree stages moderate (E = 0.3 to 0.6).

ADILI, A., KARTAWINATA, K., SOEDJITO, H. & SAMBAS, E. N. 2018. Tree species diversity in a pristine montane forest previously untouched by human activities in Foja Mountains, Papua, Indonesia. Reinwardtia 17(2): 133‒154. ‒‒ A study on structure and composition of the pristine montane forest previously untouched by human activities was conducted at the Foja Mountains in November 2008. We established a one-hectare plot divided into 100 subplots of 10 m × 10 m each. We enumerated all trees with DBH ≥ 10 cm which diameters were measured, heights were estimated and habitats were noted. We recorded 59 species, 42 genera and 27 families, comprising 693 trees with the total basal area (BA) of 41.35 m2/ha. The forest had lower species richness compared to those of lowland forests in Kalimantan, and Sumatra and montane forests in West Java. The Shannon-Wiener’s diversity index was 3.22. Nothofagus rubra (Importance Value, IV=47.89%) and Parinari corymbosa (IV=40.3%) were the dominant species, constituting the basis for designating the forest as the Nothofagus rubra - Parinari corymbosa association. To date, the dominance of N. rubra is unique to the Foja Mountains, as elsewhere in Papua the montane forests were dominated by N. pullei or other species. The species-area curve indicated a minimal area of 5000 m2. On the family level Fagaceae (IV=53.23%), Chrysobalanaceae (IV=40.53%) and Myristicaceae (IV=26.43%) were dominant. Verti-cally the forest consisted of four strata (A–D). In each stratum Nothofagus rubra, Platea latifolia, Parinari corymbosa and Myristica hollrungii were dominant. The diameter class distribution of Nothofagus rubra, Parinari corymbosa and Platea latifolia led us to assume that these species were regenerating well.

The activities of the community around the peat swamp forest cause disruption of the ecosystem from the sustainability of the forest area's resources. Land clearing and peatland fires also affect the presence of ferns. The new environmental conditions due to changes in land cover cause ferns to be affected by these changes. Kuala Dua Village Kubu Raya Regency has secondary peat swamp forest and open peat land due to fires 3-4 years earlier so it is overgrown with a variety of new types of flora, one of which is a type of fern. The objective of the study is to describe species diversity of ferns and their site conditions in secondary peat swamp forests and open peatlands of Kuala Dua Village, Kubu Raya District. This research was conducted with survey method using multiple plot samples. The plots determination was done by purposive sampling which was taken place on the site where there were many species of ferns land. Three plots were on each land covered condition with a plot size of 5 m x 5 m that divided into 25 of a 1 m x 1 m sub plots. The results show that 5 species of ferns found in peat swamp forest and 4 species of ferns were found on open peatlands. The species that has the highest INP value in the forest was Asplenium belangeri and the species that has the INP value in open peatland was Nephrolefis falcata. Dominant Index, Spesies Diversity Index and Spesies Abudance Index were 0,12 and 0,18; 0,30 and 0,36; 0,51 and 0,52 on the forest and open peatland respectively. The Similarity Index value (IS) of ferns in secondary peat swamp forest and open peatland is 44%. The study shows dissimility of species fern in peat swamp forests and open peatlands.Keywords: Open peatland, Pteridophyta, secondary peat swamp forest
