Abstract

Corridor area of Gunung Halimun Salak National Park was degraded and fragmented by human activities. However, little is known about recovery process in tropical degraded forest under different land use history. To clarifyvegetation structure and forest recovery related to land use history we placed 22 plots (11 of 10 x 10 m2 in abandoned plantation and 11 of 20 x 20 m2 in secondary forest, respectively). DCA (Detrended correspondence analysis) discriminated the plots into three community groups. Swieteniamacrophylla –Agathisdammaa community in abandoned plantation where had a land use history of clear felling.Maesopsiseminii–Cyathea spp. community had a history of severe human disturbance. Fagaceae-Schimawallichii was in less disturbed forest. Below the plantation canopy, light tolerant species, weeds, grasses, and fern of Dicranopteris linearis were dominant. Some exotic plants spread to the disturbed forest. The less disturbed forest in distant area from village remained in good condition as indicated by dominancy of old forest species. For the forest rehabilitation in severely degraded area, human intervention by planting native species can be suggested to avoid invasive species occupancy as well as accelerate forest recovery.

Abstract

SUZUKI, E. 2010. Tree flora on freshwater wet habitats in lowland of borneo: does wetness cool the sites?. Reinwardtia 13(2): 199-210. - The floristic records of lowland forests of Borneo in dry (not inundated) and wet (kerangas and peat swamp) habitats, and in montane forest of West Java were compared to clarify the characteristics of the flora in the lowland wet habitats. The data was flora of trees (DBH is equal to or more than 4.8 cm) in 12, 7, and 3 plots in dry lowland, wet lowland and mountain, respectively (20.9 ha in total). Plots in dry habitats had 42 to 53 families in 1 ha, except two plots on river banks (33 and 37 families). Plots in wet habitats and in mountain had 32 - 45 and 21 - 40 families, respectively. The clusters of plots in dendrogram using number of species in family mostly coincided with the difference in habitats. The preference for wet habitats existed in some families: Aquifoliaceae, Icacinaceae, Thymelaeaceae, Guttiferae, Myrtaceae, and Anacardiaceae though most families including Dipterocarpaceae and Euphorbiaceae had no tendency. Myristicaceae, Meliaceae, and Sapindaceae preferred dry habitats. Some species consisting of the flora of tropical mountains were found occasionaly in wet habitats of lowland though very rarely in dry habitats. There was a weak but singificant correlation between preference for wet habitats and abundance in Japanese tree flora of each family. These results suggest that the wet habitat where the forest floor is periodically filled with water has cooler environment than dry habitat, and families adapted cooler climate prefer the former.

Abstract

Vegetation types in fresh water swampy areas: Mandor in West Kalimantan and Lahei in Central Kalimantan, were compared.There were three types: kerangas, kerangas shrub and peat swamp forest. Kerangas forests in both areas had similar flora in some extent.That of peat swamp was very different from kerangas though both vegetations distributed in adjacent area.
