The changing pattern of vertical stratification along an altitudinal gradient of the forests of Mt Pangrango, West Java

Abstract: The forest structure of the montane rain forest of Mt Pangrango, West Java, was examined by measuring tree height, height of the lowest living branch, and crown area The crown mass of one plot was stratified into one-metre units and thenceforth the total crown area at each metre height level was calculated Although the maximum total crown area was found at 25 m above the ground, a more or less similar crown area was found between the 5 and 35 m levels As for species, Schima wallichii and Castanopsis javanica dominated the first layer with the largest crown area, while Lithocarpus pseudomoluccus and Persea rimosa occurred in lower frequency in the same layer These four species were the main canopy species in the 1600 m plot In the middle layer, Polyosma ilicifolia was dominant In the lower layer, Turpinia sphaerocarpa and Saurauia pendula were the major species; the latter, especially, was abundant around 10 m above the ground with coverage similar to upper layer species This stratification pattern changed with altitude and four groups of species were recognised, ie, 1) upper layer species in montane forest, 2) species changing their habitat along a changing altitude, 3) subalpine species, and 4) lower layer species regardless of altitude
