1. INTRODUCTION

The study of any ecosystem and its biodiversity is apart of the curriculum of this laboratory
course. Ecosystem study is essential to witness the functioning of predominant animals and plants
in their habitat.

Biodiversity is the number of different species living in an ecosystem. For example, a region with
high biodiversity will have many different types of species that live there. Forests are often
considered biodiversity hotspots because of the great number of unique species that live there.
An ecosystem consists of all organisms and the physical environment with which they interact.
These biotic and abiotic components are linked together through nutrient cycle sand energy flows.
Energy enters the system through photosynthesis and incorporate into plant tissues.

We visited Ranthambore National Park in Rajasthan, India, with an area of 1,334 sq km (515 sq
mi). It is bounded to the north by the Banas River and to the south by the Chambal River. It is
named after the historic Ranthambore Fort, which lies within the park. The national park covers a
total area of 392 sq km (151 sq mi), including buffer zone. The core area is about 275 sq km (106
sq mi). The tiger reserve area was about 334 sq km (129 sq mi). Today, it covers an area of 1,334
sq km (515 sq mi). The elevation is about 215 to 505 meters above mean sea level. The land
features dense tropical dry forest, open bushland and rocky terrain interspersed with lakes and
streams. Ecoregion includes Khathiar-Gir dry deciduous forests.

5. AN OVERVIEW OF RANTHAMBORE NATIONAL PARK -


A BRIEF SUMMARY

Ranthambore National Park is a national park in Rajasthan, India, with an area of 1,334 km 2
(515sqmi). It is bounded to the north by the Banas River and to the south by the Chambal
River. It is named after the historic Ranthambore Fort, which lies with in the park.

The Kingdom Of Tigers situated in the Southeastern Part Of Rajasthan, Ranhambore National
Park is located approximately 130 Kilometres from Jaipur, the capitalcity of Rajasthan, the
park is nestled between the Aravali and Vindhya Hillranges.

The absolute location of this place is–

Latitude: 26°02’8.40”N

Longitude: 76°28’29.99”E

Ranthambore National Park harbours dry deciduous forests and open grassy meadow. The
park is divided into different zones, each offering a unique perspective on the wildlife and
vegetation.
5
The lands cape of the Ranthambore forest is mostly rough and craggy with low hills and steep
out crops. The narrow water streams drained in the river Banas in the northern region and in
the river Chambal in the southern region of the forest. Both the rivers in Ranthambore, the
Chambal and the Banas are having the prominent ravines in the area which holds very
significant value to enhance flora and fauna in the region.

The Ranthambore National Park has internal drainage and has no connection with any river
system, even though two rivers bound the Park in it’s north and south side.

The region of the Ranthambore National Park is having the sub-tropical dry climate with
mainly three seasons all round the year –summer, winter and monsoon. The summer season
starts from the month of April and ends in July when monsoon starts. Monsoon stays from
July to September thus the park is closed during this time. During the October month, the
season changes from monsoon to winter and the winter season starts from November and stay
still the first half of March. The month of March is the transition month for weather as it
changes from winter to summer.

5.1. Ranthambore Tiger Reserve

Ranthambore National Park is one of the biggest and most renowned national parks in Northern India.
Ranthambore National Park is located about 13.5 kilometres from the city of Sawai Madhopur in
Rajasthan. Located at the junction of the Aravali and Vindhya hill ranges.The Park covers an area of
approximately 400 sq. km, and if combined with the area of Sawai Man Singh Sanctuary area, is around
500 sq. km. It was once considered as one of the famous and former hunting grounds of the Maharajas of
Jaipur.

Ranthambore National Park was established initially as Sawai Madhopur Game Sanctuary in 1955 by the
Government of India. In 1973, it was declared as one of the Project Tiger reserves in India. It was on 1st
November, 1980 that Ranthambore was declared a national park, while the forests located beside it were
named Sawai Man Singh Sanctuary & Keladevi Sanctuary.

Being a tiger reserve, Ranthambore has a large number of Tigers in its habitat. It also has other big cats
such as the Leopard, Caracal, Jungle Cat and the Fishing Cat along with animals such as the Desert Fox,
Indian Fox, Indian Wild Boar, Palm Civet, and Hanuman Langurs

8.3.QUADRAT SAMPLING TO DETERMINE ANT DIVERSITY
Working Principle: A quadrat is a frame, traditionally square, used in ecology and geography to
isolate a standard unit of area for study of the distribution of an item over a large area. The quadrat is
suitable for sampling plants, slow-moving animals, and some aquatic organisms. When an ecologist
wants to know how many organisms there are in a particular habitat, it would not be feasible to count
them all. Instead, they would be forced to count a smaller representative part of the population, called a
sample. Sampling of plants or slowly moving animals (such as snails) can be done using a sampling
square called a quadrat. A suitable size of a quadrat depends on the size of the organisms being sampled.

Study site: Forest field near hotel

Date and time:

Working group: We were divided into 4 groups and observe different insects within the particular
area.

Procedure: In the selected site of study the nails were hammered firmly in the soil without damaging
the vegetation. Four nails are fixed to make a square. Each end of the nails is tied using rope to make a
18’’ x 18” = 324 square inch quadrat. 3 quadrats were made in different places. We were divided into 3
groups and observe different insects within the particular area.

8.4.STUDY OF FOREST FLORA BY QUADRAT METHOD

The Quadrat method of studying vegetation has become an integral part of many of the more important
ecological investigations.

Working Principle:A Quadrat is a frame, traditionally square, used in ecology and geography to
isolate a standard unit of area for study of the distribution of an item over a large area. The quadrat is
suitable for sampling plants, slow-moving animals, and some aquatic organisms. When an ecologist
wants to know how many organisms there are in a particular habitat, it would not be feasible to count
them all. Instead, they would be forced to count a smaller representative part of the population, called a
sample. Sampling of plants or slowly moving animals (such as snails) can be done using a sampling
square called a Quadrat. A suitable size of a Quadrat depends on the size of the organisms being sampled.
For example, to count plants growing on a school field.

Study site: a small bushy region with many native plant vegetation outside the protected area near hotel

Date and time: 27.04.2022; time 12.45 p.m.-1.45 p.m.

Working group: We were divided into 4 groups and observe different insects within the particular
area.

Procedure: In the selected site of study the nails were hammered firmly in the soil without damaging
the vegetation. Four nails are fixed to make a square. Each end of the nails is tied using rope to make a 5ft
x 5ft Quadrat. 6 quadrats were made in different places. All students worked together to calculate the
numbers of plants in the Quadrats.

Observation:
Seven species of plants were observed in different numbers. The numbers are given below:

8.5. STUDY OF FLORA USING LINE TRANSECT METHOD
Working Principle:Line transect sampling studies or line intercepts involve a count-in of organisms
in a straight-line taking segments or transects of equal size to get an estimated density in the area
sampled. It is a hybrid between cover and frequency. The measure is of how many segments are
intercepted by the species in question. The density of particular species can be predicted where the
maximum density lies.

Study Site: A field near Hotel

Date and Time: 27.04.22; 12.45p.m.-1.45 p.m.

Working Group: All students worked together during this study

Procedure: In this line transect study, we have divided into 7 groups and estimated the biodiversity of
different plants. In this study, we hammered a nail on the groundand two ropes of 5 ft were drawn at the
left and right sides of that line. Then two nails were hammered on the end of both. Now 3 ropes of 50 ft
were measured from all 3 nails and at the end of the ropes, 3 nails were hammered. We got an area of
50ft x 10 ft. We divided this area in 5 squares of 10ft x 10 ft (A,B,C,D and E) and conducted the line
transect.

Observation:
Three species were observed during the line transect. The data is given below:

CALCULATION OF DIFFERENT BIODIVERSITY INDICES:

1. Information statistics index:

So. H = - (-1.539) = 1.539

2. Dominance index:

So, D= 1/0.281= 3.559

3. Species richness index:

Menhinick's index:

D= s / √N, Here, s= Number of species = 12

N = Total number of organisms of all species = 282

D=12 /√282 = 0.7146

s= 12

So, H/ln s=1.539/ln12= 0.619

8.7. STUDY OF INSECT POPULATION COLLECTED BY LIGHT


TRAP
Introduction: The use of light for sampling night-flying insects is a long-standing technique. Light
trapping is most useful for inventory work or to help determine the geographical distributions of night-
flying insects. This is because many species that are trapped at night are practically undetectable by other
sampling methods. Light trapping for native insects potentially reveals a rich diversity of many different
insects. It provides information about biodiversity across all seasons, landscapes, ecological areas,
altitudes and times of night.

Working Principle: Light does not attract insects—it confuses them and intercepts them from their
chosen flight path. Some insects fly repeatedly around the light, others simply settle at varying distances
from the light and may fly off after varying times. The insects are actively caught and encouraged into the
trap. Any bright white or bluish light is suitable although mercury bulb can be used. Collection of a light
trap provides a significant clue to the diversity of insects active at night, their respective affinity to
different wavelengths of light and to understand and predict how the population functions.

Study site: This study was performed at Hotel premices.

Date and Time: 25/04/22, 9:00-9:30 PM left overnight.

Procedure:
i. Take a bucket and make 4 holes at the top rim and one larger hole at the bottom rim.
ii. Adjust a small sized light shade on the bucket in the inverse direction.
iii. Fix four rods with screws/nuts with the bucket for holding up the large sized light shade.
iv. Hang the light trap on the large sized light shade. Drainage hole on the bucket should be kept
closed by the rubber plug while filling it with soap water/kerosinized water.

v. Mount the lamp or the bulb on the frame, five meters from the ground.
vi. Collect/drain out trapped insects periodically.

24
Working Group: All the team members performed this study.

Observation: We found different types of insect species from this light trap technique. These are as
follows-

Sl.no. Species Individuals (n)


1 Lepidoptera 6
2 Hymenoptera 4
3 Dictyoptera 3
4 Coleoptera 15
5 Diptera 10
N= ∑ (n) 38

Result and Interpretation:From the result we can interpret that there is highest distributions in case
of Coleoptera and lowest abundance is in case of Dictyoptera.

Conclusion: We have set the light trap at one site near our hotel. Most of the collected insects were
from order Coleoptera. If we set some more traps else where, then we may get different results.

8.8. BIRD WATCHING BY LINE TRANSECT

Working Principle: In statistics, more specifically in biostatistics, line-intercept sampling is a


method of sampling elements ina region whereby an element is sampled if a chosen line segment, called a
“transect”, intersects theelement. A tape or string laid along the ground in a straight line between two
poles as a guide to asampling method used to measure the distribution of organisms. Sampling is
rigorously confined toorganisms that are actually touching the line. A line transect is carried out by
unrolling the transect linealong the gradient identified. The species touching the line may be recorded
along the whole length ofthe line (continuous sampling). Alternatively, the presence, or absence of
species at each marked point isrecorded (systematic sampling).Linetransects are used when you wish to
illustrate a particular gradientor linear pattern along which communities of plants and, or animals change.
They provide a good way ofbeing able to clearly visualize the changes taking place along the line. A
transect is a line across a habitator part of a habitat. It can be as simple as a string or rope placed in a line
on the ground. The number oforganisms of each species along a transect can be observed and recorded at
regular intervals.

Study Site: Ranthambore National Park and adjoining area outside the protected area

Date and Time:


● Day 2- 26.04.2022 [Site-A]; 05:45 AM - 09:20 AM
● Day 3- 27.04.2022 [Site-B]; 05:45 AM - 09:30 AM

26
Procedures: Line transect sampling is a distance sampling method for estimating the abundance of
wild animalpopulations. One key assumption of this method is that all animals are detected at their initial
location.Animal movement independent of the transect and observer can thus cause substantial bias.

1. The essential feature of line transects is that one walks along a straight path and records the individuals
seen and their perpendicular distance from the transect line.

2. Line transects are best used for visible animals in open habitats. The sample size should be at least 40
sightings, and better results are obtained from 60-80 sightings.

3. Not all individuals need to be seen for this method to work. An illustration of the basic measurements
that can be taken for each individual sighted along a line transect in the direction indicated by the arrow.
The key measurement is the perpendicular distance (x i). If the sighting distance (r i) is easier to record in
the field, the sighting angle (Ɵ) must also be measured. The perpendicular distance x= r.sinƟ

9. LIST OF FLORA & FAUNA IN THE ENTIRE TOUR

It is estimated that there are nearly 300 species of vegetation found in and around the
Ranthambore reserve forest. The area in the proximity of the Thar Desert gets very scant rainfall
so the plant life here consists mainly of dry deciduous type.
The most dominant plant of all the plant species of the Ranthambore National Park is the Dhok
(Anogeissus pendula). This tropical tree constitutes of more than three-fourth of the vegetation of
this national forest. Many other plants are also found, Which are as follows-
28
 Babul (Accasia nilotica)
 Gum (Sterculia urens)
 Gurjan (Lannea coromandelica)
 Kadam (Authocephalus cadamba)
 Khair (Accacia catechu)
 Khajur (Phoenix sylvesris)
 Kakera (Flacourtia indica)
 Karel (Capparis decidua)

10. PROJECT TIGER- A BRIEF SUMMARY
Project Tiger is a tiger conservation programme launched in April 1973 by the Government of India
during Prime Minister Indira Gandhi’s tenure. The project aims at ensuring a viable population of the
Ranthambore tiger in its natural habitats, protecting it from extinction, and preserving areas of biological
importance as a natural heritage that represent the diversity of ecosystems across the tiger’s range in the
country. The project’s task force visualized these tiger reserves as breeding nuclei, from which surplus
animals would migrate to adjacent forests. Funds and commitment were mustered to support the intensive
program of habitat protection and rehabilitation under the project. Project Tiger’s main aims are to:

• Reduce factors that lead to the depletion, of tiger habitats and to mitigate them by suitable management.
The damages done to the habitat shall be rectified to facilitate the recovery of the ecosystem to the
maximum possible extent.

• Ensure a viable tiger population for economic, scientific, cultural, aesthetic and ecological values.

• Expanding the undisturbed areas for tiger by reducing human pressure.

• Repair the relationship with local people who share the tiger habitat by fielding strategies for
coexistence.

The monitoring system M-STrIPES was developed to assist patrol and protect tiger habitats. It maps
patrol routes and allows forest guards to enter sightings, events and changes when patrolling. It generates
protocols based on these data, so that management decisions can be adapted. Camera trap method is also
exercised in the Ranthambore National Park. The analysis of the flanks of the tigers are assisted by WII-
Dehradun.

Ranthambore National Park is home to the largest number of tigers in India and perhaps in the world also.
This has put the Ranthambore on the international tourism map. In 2022,according to NTCA’s recent
census,Ranthambore had an estimated population of 69 tigers.As per an update by the park
authorities ,there has been an increase in the number of tigers in the park ,totaling up to around 88
tigers,which is more than a 25% increase in their population in just a year.

Ranthambhore Tiger Reserve has the potential to act as a source for tigers to other neighbouring forested
areas such as Kuno-Palpur to the east, in the adjoining state of Madhya Pradesh, Van vihar Dholpur to the
North and Gandhi sagar, in Madhya Pradesh (through Mukundra – Ramgarh Vishdhari) to the south.

There are 3 corridors which require restoration-

1. Ranthambhore – Keladevi WLS – VanVihar WLS (Dholpur)

2. Ranthambhore – Kuno –Palpur WLS (M.P.)

3. Ranthambhore – Ramgarh Vishdhari – Mukundra hills

32
Ranthambore forest was brought under the national project and declared a tiger reserve along with eight
other sanctuaries and national parks in 1973. In 1980, 274.50 sq. km of the forest here was notified as
Ranthambhore National Park.

The Project Tiger is headed by the Field Director who is a conservator. His team includes a Deputy Field
Director who is of the rank of a Divisional Forest Officer, an Assistant Field Director who is of the rank
of Additional Divisional Forest Officer and 12 Range Officers.

Wireless communication systems and outstation patrol camps have been developed within the tiger
reserve, due to which poaching has declined considerably. Fire protection is effectively done by suitable
preventive and control measures. Voluntary Village relocation has been done in many reserves, especially
from the core area. Livestock grazing has been controlled to a great extent in the tiger reserves. Various
compensatory developmental works have improved the water regime and the ground and field level
vegetation, thereby increasing the animal density.

Research data about vegetation changes are also available from many reserves. Plans include the use of
advanced information and communication technology in wildlife

protection and crime management in tiger reserves, GIS-based digitised database development, and
devising a new tiger habitat and population evaluation system.

11. THREATS TO FOREST ECOSYSTEM


Forests have long been threatened by a variety of destructive agents. Today, the frequency, intensity and
timing of fire events, hurricanes, droughts, ice storms and insect outbreaks are shifting as a result of
human activities and global climate change, making forest ecosystems even more prone to damage. This
issue of Unasylva examines the threats posed by a number of biotic and abiotic agents and some of the
measures for overcoming them.
Natural threats such as fire, insects and diseases are integral to forest dynamics. However, they can
disrupt the flow of goods and services from forests by affecting tree growth and survival, water quality
and yield. and biodiversity. Also considered are alien invasive species pests, microorganisms or trees that
are non-native to a particular ecosystem and whose introduction causes, or is likely to cause, economic or
environmental harm. Many introduced tree species have high socio-economic and environmental value,
but they can give cause for concern when insufficient consideration is given to the context of their use
and managemeni. Measures to protect forests from all threats must be an integral part of sustainable forest
Management.

 Deforestation: One of the major challenges faced by forest ecosystem is deforestation.


Deforestation is nothing but cutting the forests for some other purpose other than for forest use.
Huge amounts of forests are cut down every year by the state governments for agriculture,
settlements, constructing multipurpose projects, etc. Some contractors even do illegal
deforestation for monetary benefits. As a result of deforestation, the quality of soil also gets
degraded because of soll erosion which in turn cannot sustain forests further.
 Forest Fires: Though forest fires are not major threats to forests in India but they are a common
phenomenon the world over. Forest fires that happen either due to natural or man-made causes
destroy the forests and hence cause deforestation.

33
 Illegal logging: Illegal logging is the catalyst to deforestation around the globe, threatening some
of the world’s most important forests in terms of conservation value. Predatory logging brings
roads deeper into the forest, which in turn fuels more logging, impacts Indigenous Peoples and
traditional local communities, as well as harming wildlife. Illegal logging is a global-multi-
country issue Greenpeace offices around the world have worked to investigate, document, and
stop.
 Insect pests: It cause significant damage to agricultural products intended for human foods and
animal feeds. In addition to direct losses caused by insects to plant systems, fruits, and seeds,
these biotic agents cause indirect losses because they leave important contaminants such as body
parts or exoskeletons, insect eggs, and off-odors on produce. There are more than six million
species of insect although only 20–30 of these are important pests for major crops. The key for the
proper insect pest management is to understand their biology and behavior, the kinds of damage
they produce, and application of proper integrated pest management in order to achieve a crop
production system that optimizes the use of natural resources, protects the environment, and
maximizes output in a sustainable way.
 Climate Change: Climate changes directly and indirectly affect the growth and productivity of
forests: directly due to changes in atmospheric carbon dioxide and climate and indirectly through
complex interactions in forest ecosystems. Climate also affects the frequency and severity of
many forest disturbances.
 Forest degradation: Degradation is a process in which the biological wealth of a forest area is
permanently diminished by some factor or by a combination of factors. "This does not involve a
reduction of the forest area, but rather a quality decrease in its condition." The forest is still there,
but with fewer trees, or less species of trees, plants or animals, or some of them affected by
plagues. This degradation makes the forest less valuable and may lead to deforestation. Forest
degradation is a type of the more general issue of land degradation. Deforestation and forest
degradation continue to take place at alarming rates, which contributes significantly to the
ongoing loss of biodiversity.

12. CONCLUSION

Zoology is an important branch of science and is the study of animal life. However, an extensive study
cannot be made on the basis of theory alone. To gain a complete knowledge of the animals we must also
have a practical insight on the animal and its habitat which can be acquired by routine visits to the habitat
of organisms. Biodiversity study is an appropriate method to observe the ecosystem.

The aim of biodiversity study is a firsthand gain of knowledge about animals in their natural habitat by
field study, through which we can familiarize ourselves with several animal life as found in the world of
which we have so far only read about. The main aspect of this study is to point out the different factors
which are affecting the environment in positive and negative ways. Both of these purposes are fulfilled in
our study.

The concept of Biodiversity Conservation has taken the center stage during the last decade, percolating to
all walks of public life including media and politics. Also, the concepts of National Park, Wildlife
34
Sanctuary and Wildlife Conservation are no longer new in our country. There is still, however, a great
deal of confusion in the minds of common people about the exact meaning of Biodiversity, Wildlife and
Conservation, what they include, how they are managed and what role they play in the life of people.

On this count we were really fortunate to have got a chance to visit Ranthambore National Park,
Rajasthan, famous for its large tiger population. During our short visit to this National Park we were able
to realize that unless one visits such areas equipped with the right kind of interest and intention, one's
knowledge of Biodiversity, wild-life and conservation remains only.
