The Indian subcontinent is blessed with a natural habitat of a large and varied wildlife. We can find some of the most magnificent as well as the rarest wildlife species of the world in the country. The beauty and variety we see in the jungles of India is difficult to be expressed in words. However, the past few decades have seen the greed and negligence of human beings leading to large-scale poaching, habitat destruction, resulting in animal - human conflict with rapid decline in the population of most of the wild animals and birds. 4. Conservation of Wildlife in India has slowly and gradually been understood by all. Today, efforts are being made towards wildlife conservation to preserve this natural wealth. Numerous wildlife conservation projects have been undertaken in India, both, at the government, as well as the individual level, to protect the wildlife of the subcontinent. AIM 5. To acquaint the cadets about Wildlife Conservation and Projects in India. PREVIEW 6. The lecture will be conducted in following parts:- (a) Part I - Wildlife Conservation. (b) Part II - Wildlife Projects in India. (a) PART I : WILDLIFE CONSERVATION Need for Conservation 7. Threats to Wildlife.

Natural Vegetation and Wildlife of India
NATURAL VEGETATION AND WILDLIFE OF INDIA Natural vegetation refers to a plant community that has been left undisturbed over a long time, so as to allow its individual species to adjust themselves to climate and soil conditions as fully as possible. Himalayan heights are marked with temperate vegetation. The Western Ghats and the Andaman Nicobar Islands have tropical rain forests. The deltaic regions have tropical forests and mangroves. The desert and semi desert areas of Rajasthan are known for cactii, a wide variety of bushes and thorny vegetation. TYPES OF FORESTS Tropical Evergreen and Semi Evergreen forests Tropical Deciduous forests Tropical Thorn forests Montane forests Littoral and Swamp forests TROPICAL EVERGREEN AND SEMI EVERGREEN FORESTS Tropical Evergreen These are found in the western slope of the Western Ghats, hills of the north-eastern region and the Andaman and Nicobar Islands. They are found in warm and humid areas with an annual precipitation of over 200 cm and mean annual temperature above 22°C. They are well stratified, with layers closer to the ground and are covered with shrubs and creepers, with short structured trees followed by tall variety of trees. The trees reach great heights up to 60 m or above. There is no definite time for trees to shed their leaves, flowering and fruition. These forests appear green all the year round. Species found in these forests include rosewood, mahogony, aini, ebony, etc. Semi Evergreen They are found in the less rainy parts of these regions. Such forests have a mixture of evergreen and moist deciduous trees. The undergrowing climbers provide an evergreen character to these forests. -

Multivariate Morphometric Variability in Sardine, Amblygaster Clupeoides (Bleeker, 1849), from the Bay of Bengal Coast, Bangladesh Md Abu Hanif1* , Muhammad A
Hanif et al. The Journal of Basic and Applied Zoology (2019) 80:53 The Journal of Basic https://doi.org/10.1186/s41936-019-0110-6 and Applied Zoology RESEARCH Open Access Multivariate morphometric variability in sardine, Amblygaster clupeoides (Bleeker, 1849), from the Bay of Bengal coast, Bangladesh Md Abu Hanif1* , Muhammad A. B. Siddik1, Md Aminul Islam2, Md Reaz Chaklader1,3 and Ashfaqun Nahar4 Abstract Background: Sardine Amblygaster clupeoides is a reef-associated oceanic species having long-standing socioeconomic and ecological importance along the coast of Bay of Bengal, Bangladesh, but less is known about the morphometric variability of the species. To uncover this, morphometric variability of A. clupeoides based on truss network technique was employed Results: A total number of 160 specimens from four coastal regions (Sundarbans, Kuakata, Bhola, and Cox’s Bazar) of the Bay of Bengal coast were used to determine whether separate populations could be distinguished. To test the hypothesis of differentiation, each sample was subjected to morphometric measurements consisting of twenty-eight landmarks. In one way ANOVA analysis, twenty-six out of 28 morphometric measurements showed significant differences among the four populations. The principal component analysis indicated shape variation and explained 70.11% of the total variance. About 68.39% of individuals into their original group were correctly classified in discriminating space, as determined by discriminant function (DF) analysis. Conclusion: Morphometric traits like body length, body depth, body diagonal, body height, head length, head depth, mouth length, anal fin length, dorsal fin length, and caudal length diagonal were mainly responsible for variation and discrimination of populations.
