Chapter 5 Biodiversity Conservation Of Some Endangered Species Of India Summary
WBBSE Class 10 Endangered Species in India
- Many organisations take part in the conservation of biodiversity. But one of the organisations which play a major and most important role in biodiversity conservation in India is JFM.
- The full form of JFM is joint forest management. It is regulated by Govt. of India. It was first implemented successfully in the Arabari forest of Medinipur for the conservation of the sal tree. Local people take part in this programme.

- Another organisation other than JFM is PBR. The full form of PBR is Peoples’s biodiversity register. According to the biodiversity act 2002, a data bank is prepared, where the comprehensive information on the availability and knowledge of local biological resources and their way of usage are registered is called PBR.
- Various measures are taken for the conservation of certain animals like lions, tigers, crocodiles, red pandas etc. in India. In Sundarban biosphere reserve tiger is conserved, in Manas national park rhino, in Gir national park lion, in Bhitarkanika, crocodiles are and in Barsi red panda isonserved.
Chapter 5 Biodiversity Conservation Of Some Endangered Species Of India LAQs
Question 1. Briefly describe the concept of JFM and PBR and the role in the conservation of biodiversity.
Part Question, Discuss any two roles of the People’s Biodiversity Register (PBR) in Conserving local biodiversity
Part Question, What are the roles of forest Management in the conservation of biodiversity?
Answer:
Joint Forest Management or JFM:
The proper management of biodiversity by the joint action of local people and the forest department of the state government which is approved by the Indian government, is known as Joint Forest Management or JFM.
Role of JFM in the conservation of biodiversity:
In conservation of biodiversity, the role of JFM is as follows
- The committee, formed by the local residents of any forest area, maintains coordination with the state forest department regarding the conservation of the biodiversity of that forest.
- The JFM committee members keep a vigil on the forest area along with their daily activities regarding forest fire, encroaching of the forest area, poaching, felling of trees etc. and report it immediately to the forest department in case of any adversity.
People’s Biodiversity Register or PBR:
It is a ready reference prepared by the central forest department in accordance with the Biodiversity Law 2002. This document contains detailed information on the availability of local biodiversity, their habits and habitats, other behaviours, their ecological importance etc.
Life Science Class 10 Wbbse
Role of PBR in the conservation of biodiversity:
In conservation of biodiversity, the role of PBR is as follows-
- PBR provides correct information about the biodiversity of the local areas so that, the rare and endangered animals and plants can be conserved properly.
- It makes people aware of the importance of the conservation of biodiversity and involves them directly with the conservation project.
- PBR makes the people aware of the sustainable utilisation of forest resources and helps in the economic development of the area.
- PBR provides correct geographic information about conserved areas.
- Identify endangered species and collect information about the conservation of these species.
- Gather knowledge about local species and their cultural and social value.
- Gives an idea about the obtained product from species and their value along with their collection and transport procedure.
Question 2. Mention the causes of the decrease in the tiger population in India. Briefly describe the measures taken to protect tigers.
Answer:
Causes of decrease in tiger population:
The causes which resulted in the decrease of the population of tigers are mentioned below.
1. Poaching:
The value of tiger skin is as high as 12500 $ in the international markets. The bones, teeth, and claws also attract poachers to kill tigers indiscriminately.
2. Squeezing of natural habitat:
With the increase in human population, forest areas are being encroached for building residential places. As a result, the normal habitats of tigers are being squeezed. This is one of the most important causes of the decrease in the tiger population.
3. Problem in reproduction:
Tigers prefer dense forests for breeding. With continuous human intervention, their natural breeding habitat is being disturbed. Moreover, due to the absence of partner, the number of tigers is decreasing.
Measures are taken to protect tigers
In 1969, a general meeting of IUCN was held in New Delhi. Based on the resolution of that meeting, the killing of tigers was banned since 1970. After two years, the Government of India framed and implemented the Wildlife Conservation Act (1972).
In 1973, a committee, named National Tiger Conservation Authority (NTCA) was formed by the Government of India under the recommendation of IUCN and WWF. It was the first step exclusively for the conservation of tigers in India.
Primarily, the conservation project was started in nine sanctuaries in 1973. Now there are 42 different projects running in this country. Out of them Jim Corbett National Park in Uttarakhand is an important tiger conservation centre in India.

Question 3. Mention the causes of the decrease in the population of rhinos in India. Briefly describe the measures taken to protect rhinos.
Part Question, Summarize which conservation measures have been adopted to increase the population of an endangered mammal exclusively found in the swampy grasslands under the foothills of the Eastern Himalayas.
Answer:
Causes of decrease in the population of rhino in India
The causes which resulted in the decrease of the population of rhinos are mentioned below.
1. Squeezing of natural habitat:
Due to the increasing human population, the forest areas are being encroached on for human residential purposes. As a result, the normal habitats of rhinos are being decreased. This is one of the most important causes of the decrease in the population of rhinos.
2. Poaching:
The value of rhino horn is very high in the East Asian markets. People, there have a baseless belief that the rhino horn has immense medicinal importance. For this purpose, the poachers kill rhinos indiscriminately and cut their horns.
3. Low birth rate:
The rhinos have very low birth rate. The gestation period is very long (479 days). That is why the population size does not grow quickly.
Measures are taken to protect rhinos
About 85% of the single-horned rhino (Rhinoceros unicornis) are found in Assam. Due to certain human actions, the number of the rhino population was decreasing very fast.
In view of this fact, WWF (World Wildlife Fund for Nature) and the forest department of Assam have jointly taken an initiative named IRV 2020 (Indian Rhino Vision 2020). The objective of this project is to increase the population of rhinos to 3000 by the year 2020.
The success of the project has already been established. The number of rhinos in Assam reached 2544 in 2013. According to the census of 2013, the population of rhinos is exclusively in the Kaziranga National Park reached 2319 from 1855.
Regular surveillance, restricted ecotourism and strong implementation of laws have made the project successful. Rhino conservation has also become an integral part of several other national parks. Gorumara National Park is one of them.

Question 4. Mention the causes of the decrease in the lion population in India. Briefly describe the measures taken to protect lions.
Answer:
Causes of decrease in the lion population in India:
The causes which resulted in the decrease of the population of lions are mentioned below.
1. Squeezing of natural habitat:
Due to the increasing human population, the forest areas are being. encroached for human residential purposes and cultivation. As a result, the normal habitats of lions are being squeezed. Railway tracks and roadways through the forest result in the accidental death of the lions.
2. Poaching:
The value of lion skin is very high in the international markets. The bones are used in Ayurvedic medicines. Some people like to keep the teeth and nails of lions in their collection as a sign of power. Due to this, the poachers kill lions indiscriminately.
Measures are taken to protect lions:
Centuries back Asiatic lions were available in many West Asian countries, Due to indiscriminate hunting, the population is reduced to a few. King of Junagarh was the first person to take a move towards the conservation of lions.
He banned the hunting of lions in 1910. The ban was continued even after independence. In 1960 and 1970, the Gir forest was declared as a sanctuary and national park respectively.
To protect Asiatic lions, the state government of Gujarat has taken an initiative named Gir Lion Project. Since 1974, the population of lions started increasing. According to the census 2015, the number of lions in Gir National Park is 523.
In the year 2015 gradually the central ministry of Environment formed a high-level committee named ‘Asiatic Lion Re-introduction Project’ for the conservation of Gir lions.

Question 5. Mention the causes of the decrease in the crocodile population in India. Briefly describe the measures taken to protect crocodiles.
Answer:
Causes of decrease in crocodile population in India:
The causes which resulted in the decrease of the population of crocodiles are mentioned below.
1. Poaching:
The demand for crocodile skin is very high in the international market. For this purpose, poachers kill crocodiles indiscriminately.
2. Loss of egg:
Crocodile eggs are often eaten up by jackals. Many people also consume these eggs. Therefore, the birth rate of crocodiles goes down.
3. Killing by a fisherman:
Crocodiles, often trapped in the fishermen’s net are killed. This also decreases the number of crocodiles.
Importance of Conserving Endangered Species
Measures taken to protect crocodiles:
To conserve crocodiles, Crocodile Conservation and Research Project was taken up by the government in 1974. In the next year, another project named Crocodile Breeding and Management Project or Project Crocodile was started.
This project was spread in 11 crocodile sanctuaries and 16 crocodile rehabilitation centres. To train up competent personnel, the Crocodile Breeding and Management Training Centre is established in Hyderabad in 1980.
Bhitarkanika Sanctuary is a renowned crocodile conservation centre in Odisha.
Question 6. Mention the causes of the decrease in the red panda population. Briefly describe the measures taken to protect red pandas.se in red pandas
Answer:
Causes of decrease in red panda population:
The causes which resulted in the decrease of the population of red pand are mentioned below.
1. Loss of habitat:
Regular human interventions in forests for collection of wood, and indiscriminate felling of bamboo trees reduce the size of their natural habitat. They usually feed on the leaves of bamboo. Due to the felling of bamboo trees red pandas are dying of starvation.
2. Poaching:
The soft, reddish brown fur and striated bushy tails of red pandas have always been in very high demand. That is why, poachers indiscriminately kill this beautiful animal.
3. Killing by stray dogs:
The red panda is a slow-moving animal. They are often attacked by stray dogs and are killed.
Measures are taken to protect red pandas:
The red panda is an endangered animal. To keep this animal in the race of life, certain conservational measures have been taken. In 2005, the state governments of Sikkim and Arunachal Pradesh have taken a joint project with the recommendation of the WWF.
Red panda conservation projects are running in Varsey Rhododendron Sanctuary and Kangchenjunga Biosphere Reserve of Sikkim. For this purpose, the collection of bamboo and other wood from these forests are banned completely.
About 200 local residents are trained to prepare fuel briquettes with agricultural wastes and mud, to supplement wood and bamboo.
In Arunachal Pradesh, the habitats of the red panda are taken under the vigil of the Community Conserved Area (CCA), where local people are made involved in the conservation of this beautiful endangered animal.

Question 6. What is CITES?
Answer:
CITES:
According to the proposal of IUCN (1963) in Washington, a convention named CITES (Convention on International Trade in Endangered Species of Wild Flora and Fauna) was formed in 1975.
Since its inception, this body had banned the illegal trading of endangered or rare animal and plant products and body parts on a global basis. By this action, the indiscriminate hunting and selling of endangered species have been reduced significantly.
Question 7. Why is Sundarban treated as a world heritage site?
Answer:
Sundarban treated as a world heritage site:
The mangrove forest of Sundarban is the largest of its kind. It shelters several endangered fauna and flora including the famous Royal Bengal tiger.
The root system of the dense mangrove trees prevents soil erosion and protects the area from storm. Sundarban is very rich in forest resources. Therefore, Sundarban is designated as a world heritage site.
