Abstract

Conservation of biodiversity, a growing concern today, faces multiple challenges. Although ecosystem approach has been recommended as a solution, conservation of threatened species is difficult as they are spread across the ecosystems and are often restricted to microhabitats. In this article, the importance of taxonomy, herbarium and field germplasm bank in conservation of threatened species is discussed. It is concluded that individually each of these measures has important role to play in conservation. They also complement each other in reversing the threat perspective of the species.

Keywords

Abstract

Amentotaxus assamica D.K. Ferguson (common name: Chinese yew) belongs to the gymnospermic family Taxaceae. It is one of the two members of this family found in India, the other being Taxus wallichiana. Amentotaxus is a tall dioecious tree reaching a height of 20 m with horizontal or drooping branches. It is confined to small pockets in the Eastern Himalaya, specifically in Arunachal Pradesh, India. The tree finds usage for making pillars and posts in house construction. Following the ‘critically endangered’ status assigned to the species by the Conservation Assessment and Management Prioritization (CAMP) workshop (February 2003), attempts have been made to locate and assess its population status. Gajurel et al.¹ recorded 22 individuals along with five saplings and two seedlings from Mithumna, Dalai Valley, Arunachal Pradesh, the site from where the plant was first reported by F. Kingdom War in 1928. Das et al.² reported a fairly large population at Turoo forest, Sagalee subdivision, Pampum Pare district, Arunachal Pradesh, having tree density of 40 individuals/ha.
