Abstract



Tropical montane (shola) forest are recognized to be most threatened ecosystems globally and considered has important hotspot of several endemic species and those are higher vulnerable due to the various factors which often concluded global climatic change or anthropogenic influence. However, assessing the health of the forest ecosystems may also have the forest standing structure and its dispersal syndrome to understand and its ecological constraints may provide greater insights of history of forest recruitments. This paper is to examine the different sized shola’s, where how species dispersal syndrome are structured trees communities (>5 cm DBH only tree). The results revelled that species richness shown higher at large-shola (LS) and moderate-shola (MS) than small-shola (SS). Similarly species composition shown significantly higher at LS and MS then least at SS. In LS and MS forest shown higher diversity of species belong to mammals (M) and bat-mammals (BtM). Whereas SS shown passive (Pa) dispersal species shown higher number then bird (B) and bird-mammal (BM). Overall conclusion that size of the shola’s play major role in structuring the tree species composition and diverse dispersal syndrome species are limited in SS, it’s very important to understand the ecological constraints. The forest managers may have to understand the ecological constraints before getting into intervention of montane (shola’s) ecosystem. There is scope for ecological intervention depending upon the size of the shola and species selection based on understanding the ecological constraints of shola, will have greater opportunities to restore back original ecosystem.
