Acknowledgement: I wish to express my sincere gratitude and heartfelt respect
to the Honourable Vice Chancellor, West Bengal State University, Barasat for

4. kindly granting us permission to expedite this field study tour. I further like to
express my sincere thanks to Professor Narayan Ghorai, Head of the
Department of Zoology, West Bengal State University and Dr. Chiranjib Paul,
Professor Kamal Kumar Banerjree for their active guidance, help and technical
assistance extended to us throughout the course of work. My sincere regards
are also due to all my other teachers of the department for providing us with
all necessary support during the pre journey period.
My friends of the Department deserve special mention for helping me to
prepare the field report and also thanks to Mr. Tapas Bhowmick of Hammock
Huts Holidays for his kind help. Finally I wish to express my sincere regards to
my parents for their moral support & blessing.

7. Introduction: Biology is the study of life, endow with mosaic patterns of
diversity and uniformity with all kinds of life exists on earth and also to get
ideas about processes thatmight cause such patterns. Proper biological studies
involve observations of living organisms especially in their habitats. The field
study encompassing various ecosystem patches in different landscapes
including the behaviour, home range, nich and nich width, and the
interrelationship between the organisms and their environment including
temperature, moisture, rainfall and various organic and inorganic edaphic
components- all these factors invariably linked with their habitats as well as
ecologically efficient food web, foraging patterns and influences of various
anthropogenic pressures to maintain a stable relation for the very existence of
entire surrounding biotic & abiotic paradigm. All these factors together with
different interlinked parameters are associated with the study of biodiversity.
Biodiversity is the variety of species whose distribution influences the
development of communities and eventually configures the community
structures and patterns. These are some natural areas where protected
either by legislation or by communities where maximum natural diversity of
flora and fauna can be observed at their most natural state, are designated
as forest.
Ecological importance of forest for the maintenance of quality
environment has been advocated by number of ecologists. Globally the
forested region occupies more than 4 lakh hectors of land in which 70% are
located in the tropics. Tropical forests are characterised by highly complex
ecosystem which encores an uninterrupted evolution over a million of years-
have achieved a remarkable balance within the plants & animals along with
their surroundings. This typical situation attributes a high level of species
diversity in tropical forests. The tropical forests further posses’ high level of
biological productivity due to their enhanced rates of carbon and nutrient run
over in the soil. All recent authors strongly suggested that Indian sub climates
are well suited for all kinds of forests having specific endemic flora and fauna
and thereby has been considered the one of major mega diversity countries in
the world which has at least two important hotspot areas.

8. Purpose of the field study: For the field survey, the forests were selected
mainly to get a general idea of biodiversity in a close proximity of flora &
fauna. The accessibility and the chances of encountering living organisms with
their specific domain are more apparent in forest than any other areas. Close
observation provided us the general activities, interactions and movement and
foraging patterns in their most natural state. The present study to was
conceived only to get a comparative account of two different forest areas of
North Bengal situated in two different altitude (327’- Chalsha, Chapramari area
to 6,742' – Sillerygaon and its adjoining area.)
Objectives of the present field study tour:
The main objectives of our field study tour were to:
1. Gave an idea of the basic field methods to study the forest ecosystem
and its biodiversity.
2. Enumerate the community structures mostly on the floral diversity for
studying the larval food plants of Lepidopteran study and the faunal
diversity exclusively for studying eco-zonal variation.
3. Compare the micro faunal distribution in different altitudinal zones
based on their presence and availability on temporal basis.
4. Practice some basic wild life monitoring techniques like survey,
identification, etc. in wild.
5. Prepare a species checklist on the basis of direct encounter or on the
basis of call (in case of birds).
