GCERT Class 9 Social Science Chapter 18 Solution
Brief Information: This post contains the solution for Chapter 18 Wild-Life of Class 9 Social Science (SS) of the Gujarat Board (GSEB) books GCERT.
Q.1 Answer the following questions as directed
(1) Give a list of Animal – geographical regions of India.
Ans. There are nine Animal – geographical regions in India. They are as follow:
(1) Himalayan region
(2) Ladakh and dry cold area
(3) Forested Region in lower Himalayas
(4) High lands without forest cover in Upper Himalayas
(5) Northern Plain
(6) Desert of Rajasthan
(7) Peninsular Plateau
(8) Sea coast and
(9) Nilgiri Hills
(2) Wild Life is in danger today -Explain.
Ans. The wildlife are in danger due to human greed. They face extinction due to
1) Loss of their natural habitat due to continuously decreasing forests.
2) Hunting, carried out to gut skin, meat, teeth, hair and bones.
3) Heavy grazing by domestic animals in the forests, herbivores are deprived of their food which results in decrease in their numbers. Leading to conflict between Carnivore animals and humans This conflict leads the destruction of wild life.
(3) Give brief information about different projects for wild life protection.
Ans. The government has launched various projects for protection of species from the extinction. They are:
1) Project Tiger: This Project was launched in 1973 against hunting and decreasing number of tigers. This was implemented for 9 reserved areas, under which now 48 areas are covered.
2) Lion Project: There was a time when Asiatic Lions were found up to Iran in the Asian subcontinent. Due to hunting and the reduction in forest area, these lions are now restricted to Gir forests of Saurashtra Peninsula. At one stage, their number had gone below 100. In 1972, a project was started in Gir to protect the Asiatic Lions. As a result of this Project and the timely taken steps, there are now 523 lions according to the Lion Census held in 2015.
3) Hangool Project for the rare species of Barasinga deer in Kashmir.
4) Crocodile Project for saline water crocodiles.
5) Rhino Project for the protection of Indian Rhino.
6) Snow Leopard Project.
Q.2 Answer the following questions in details
(1) Bio – diversity of India
Ans. India had great biodiversity due to presence of various geographical land-forms like vast alluvial plains of rivers, peninsular plateau, mountainous regions, swampy areas, sea coasts, dense rain forests, deciduous forest, coniferous forests in Himalayas and other higher regions. The animals seen are
1) Asian elephant in peninsular rain forests.
2)One homed rhino in swampy Brahmaputra river.
3) Snow leopards in higher Himalayas.
4) Wild goats and musk deer in Jammu – Kashmir.
5) Wild buffalo (Indian Bison ), tiger in Central India.
6) West Bengal, Ghudkhar (wildass) in Little Rann of Kachchh
7) Flamingo in water logged Greater Rann.
8) Great India Bustard in the grassland area.
9) In the water logged areas, migratory birds from cold regions come down in great number. These include Siberian crane, pelican, Tibetian duck, kunj, karkara etc.
10) Flying squirrels in the dense forests of Western Ghats.
11) Nicobari dove is a rare bird seen in Nicobar island.
12) Rare species of corals are seen in the Gulf of Kachchh and Lakshadweep Islands.
Along with mammals and many types of birds, notice should be taken of king cobra, snake›, Python, iguana (patlagho) also. Along sea coasts and other water bodies, various fishes, sea snakes, dolphin, shark, dugang (sea cow), octopus, whale etc. form a part of animal world. Besides forest, animals like fox, wolf, nilgai, deer, mongoose, rabbits, wild hog, hedgehog are seen in agricultural areas. Many birds such as nightingale, parrot, peacock, weaver bird, chibari, pilak, vulture, kabar, dhor bagla etc. are also seen roaming in these areas.
(2) Remedies for wild life conservation
Ans. A long term planning is necessary to conserve and increase forest areas. There conservation can be ensured by:
1) Preparing strong legal provisions and their strict implementation for the conservation of forest areas and wild animals.
2) Making various social NGOs give a top priority and arrange public awareness programmes.
3) Inclusion of these problems in the school syllabus and make the future citizens aware.
4) Before implementing any developmental project, its probable effects on environment and living organisms should be examined.
5) Cutting of large trees outside the forests area should be stopped, because the hollow space within them and their branches are nesting place for birds.
6) Protecting ponds, farm ponds and wetlands, which are necessary for migratory birds and for those which are inhabited near any water body.
7) Reducing pollution.
8) To manage the forest fire an anticipatory planning should be made for patrolling and safety.
