Introduction

Sahyadri e-news is CES-ENVIS's quarterly newsletter, covering the issues related to Western Ghats biodiversity. Western Ghats is rich in diversity of life. Due to unplanned developmental activities, its ecological resource base is under threat, with extensive destruction of natural habitats, widespread degradation of ecosystems and a growing burden of air and water pollution. Simultaneously, knowledge base of uses of biodiversity is also being eroded, with the present generation becoming increasingly alienated from the natural world.

We need to carefully plan on conserving, sustainably using and restoring the biological diversity of the Western Ghats. We also need to conserve and benefit from the knowledge of uses and the traditions of conservation of this biological diversity. Also, we must ensure that benefits flowing from our heritage of biodiversity and related folk knowledge percolate down to the people at the grass-roots.

Orchids exhibit an incredible range of diversity in size, shape and colour of their flowers. They are most pampered of the plants and occupy top position among all the flowering plants valued for cut flower production and as potted plants. In this Issue the articles are focusses on Orchids of Western Ghats. Orchids form 9% of our flora and are the largest family among higher plants in India. It is estimated that about 1,300 species (140 genera) of orchids are found in our country with Himalayas as their main home and others scattered in Eastern and Western Ghats.
