Abstract
A botanical survey conducted in the Nilgiri Biosphere Reserve, Madukkarai and Kanuvai forests of Tamil Nadu, Southern Western Ghats led to the validation and documentation of many RET plants. The plants are properly identified and documented. Among them 51 selected species belonging to 38 genera, 26 families and two subfamilies are presented here. Short notes about their habit, habitat, locality and endemism are also included along with three colour photos.
Highlights
As a part of this we studied the status of rare endemic and threatened (RET) plants in the Madukkarai Hills and Kanuvai Hills of Coimbatore District and recorded the details systematically
Result and Discussion: The present study is an enumeration of 51 selected endemic species belonging to 39 genera, 28 families and two subfamilies documented from different forests in Tamil Nadu
Many rare species were collected from the study area including Crotalaria scabra Gamble, Murdannia lanuginosa (Wall. ex Clarke) Brueck. (Nayar & Sastry 1990), Smilax wightii A
Summary
The Nilgiri Biosphere Reserve is one of the most diverse floristic areas of India with a mixture of both exotic and native species. From the present study the authors properly validated and documented many RET plants from NBR, Madukkarai and Kanuvai Hills of Coimbatore District, Tamil Nadu. Some of the threatened factors such as over-exploitation of natural resources and other anthropogenic activities adversely affect the existing ecosystem and it may lead to the rarity of many species in future. There is an urgent need for developing pragmatic conservation strategies for endemic plants in the southern Western Ghats, which may lead to their effective protection
