Abstract

This paper deals with the ecology, population size, status of regeneration, habitat degradation and threat status of Elaeocarpus venustus Bedd. An endemic and threatened tree species restricted to Agasthiyamalai Biosphere Reserve, southern Western Ghats, India. The population sites of this species in the study area were recorded using Global Positioning System and mapped using Arc GIS software. The population of this species is highly fragmented due to anthropogenic activities. The total stem count in all population sites from the study area was carried out to understand the population structure. A total of 181 saplings were recorded from the entire study area of which 180 are from a single site. Nearly 64% of the stems recorded in this study are mature stems. Poor regeneration was seen in population sites that were highly disturbed. In spite of good adult population, the low number of saplings shows poor germination of seeds and establishment of seedlings.
