Eastern Himalaya

Trees of Arunachal

This project aims to produce a pictorial guide book on Trees of the lowland forests of western Arunachal Pradesh.


Documentation of biodiversity is one of the primary works in ecological studies. Writing any taxonomic guide (flora, monograph, pictorial guide book etc.) is a step forward for documentation, and in biodiverse countries like India, such guides makes further biodiversity studies easier. While floras or monographs are useful for taxonomists/scientists, pictorial guide books can help even a layman for identification, which is why pictorial guide books are a necessity.

Northeast India is one of the rich biodiverse areas in India, but floristically, it is still less explored and documented. The location is at the interface of Himalayan & Indo-Burma biogeographical realm. Interactions among factors like wide elevation gradient with variable climatic condition and topography makes it the most plant-diverse area in India. However, apart from a few regional floras and plant monographs, there is no comprehensive pictorial field guide book for identification of common trees from this part of India. With our pictorial guide book of trees, we hope that nature and plant enthusiasts as well as visitors can learn, identify and engage with the trees around Pakke Tiger Reserve as well as in the low elevation forests of Arunachal Pradesh. Many tree species covered in the book also occur in low-elevation forests of Assam and other parts of North-east India, some also occur in other parts of mainland India.

THE BOOK: A Photographic Guide to the Lowland Trees of western Arunachal Pradesh

Arunachal Pradesh has the second largest forest cover among the Indian states, which is believed to harbour over 7000 plant species. In this book, we are covering around 230 species of trees which are present mainly in the lower elevations of western Arunachal Pradesh. This book will have information about taxonomy, ecology and distribution of the tree species. Being a pictorial guide, the book will also have photographs of the trees and their different parts, with leaf and floral keys providing a complete picture of the tree species for an accurate identification.
