WILDLIFE

 

Wildlife of India

India is home to a large variety of animals. It is a biodiversity hotspot with its various ecosystems ranging from the Himalayas in the north to the evergreen rain-forests in the south, the desert sands of the west to the marshy mangroves of the east. India, lying within the Indomalayan realm, is home to about 7.6% of mammal, 14.7% of amphibian, 6% of bird, 6.2% of reptilian, and 6.0% of flowering plant species. India's forest lands nurture about 500 species of mammals and 2000+ bird species. This richness of Indian wildlife has been celebrated since time immemorial. Four of India’s national symbols consist India’s mammals.

India is one of the most biodiverse regions of the world and contains three of the world’s 36 biodiversity hotspots – the Western Ghats, the Eastern Himalayas, and the Indo-Burma hotspot.It is one of the seventeen megadiverse countries. The country has seven Natural World Heritage sites, eleven Biosphere Reserves in the World Network of Biosphere Reserves and thirty seven Ramsar Wetlands.

In response to decrease in the numbers of wild animals, human encroachment and poaching activities, the government of India established a system of national parks and protected areas in 1935, which was subsequently expanded. In 1972, India enacted the Wildlife Protection Act and Project Tiger to safeguard crucial habitat. Further, federal protections were promulgated in the 1980s.

India has about 2,714 endemic Lichen species. In 2020, the Lichen Park in India was developed by the Uttarakhand Forest Department in Munsiyari.

Fauna

There are about 18500 taxa of flowering plants from India. The Indian Forest Act, 1927 helped to improve the protection and security of the natural habitat. Many ecoregions, such as the shola forests, also exhibit extremely high rates of endemism; overall, 33% of Indian plant species are endemic. Flora and Vegetation of forest cover ranges from the tropical rainforest of the Andaman Islands, Western Ghats, and Northeast India to the coniferous forest of the Himalaya. Between these extremes lie the sal-dominated moist deciduous forest of eastern India; teak-dominated dry deciduous forest of central and southern India, and the babul-dominated thorn forest of the central Deccan and western Gangetic plain.^[6] Important Indian trees include the medicinal neem, widely used in rural Indian herbal remedies. Bamboo gardens are extremely common in jungles as well as villages. States like Sikkim and West Bengal have orchids. The national flower of India, the lotus flower, is common in lakes and ponds.

Fungi

The diversity of fungi and their natural beauty occupy a prime place in the biological world and India has been a cradle for such organisms. Only a fraction of the total fungal wealth of India has been subjected to scientific scrutiny and mycologists have to unravel this unexplored and hidden wealth. One-third of the fungal diversity of the globe exists in India. The country has an array of 10 diverse biomes including Trans-Himalayan zone, Himalaya, Desert, Semi-Arid zone, Western Ghats, Deccan Peninsula, Gangetic Plain, North-Eastern India, Coasts and Islands where varied dominating regimes manifest. This enables the survival of manifold fungal flora in these regions which include hot spot areas like the Himalayan ranges, Western Ghats, hill stations, mangroves, sea coasts, freshwater bodies etc. Many fungi have been recorded from these regions and from the country, in general, comprising thermophiles, psychrophiles, mesophiles, aquatic forms, marine forms, plant and animal pathogens, edible fungi and beneficial fungi and so on. The number of fungi recorded in India exceeds 27,000 species, the largest biotic community after insects. The true fungi belong to the Kingdom Fungi which has four phyla, 103 orders, 484 families and 4979 genera. About 205 new genera have been described from India, of which 32% were discovered by C. V. Subramanian of the University of Madras. These features indicate a tenfold increase in the last 80 years.

Threats to wildlife

Habitat destruction

Habitat destruction decreases the number of places wildlife can live in. Habitat fragmentation breaks up a continuous tract of habitat, often dividing large wildlife populations into several smaller ones. Human-caused habitat loss and fragmentation are primary drivers of species declines and extinctions. Key examples of human-induced habitat loss include deforestation, agricultural expansion, and urbanization. Habitat destruction and fragmentation can increase the vulnerability of wildlife populations by reducing the space and resources available to them and by increasing the likelihood of conflict with humans. Moreover, destruction and fragmentation create smaller habitats. Smaller habitats support smaller populations, and smaller populations are more likely to go extinct.

Overexploitation

Overexploitation is the harvesting of animals and plants at a rate that's faster than the species's ability to recover. While often associated with Overfishing, overexploitation can apply to many groups including mammals, birds, amphibians, reptiles, and plants. The danger of overexploitation is that if too many individuals of a species are taken, then the species may not recover.For example, overfishing of top marine predatory fish like tuna and salmon over the past century has led to a decline in fish sizes as well as fish numbers.

Poaching

Poaching for illegal wildlife trading is a major threat to certain species, particularly endangered ones whose status makes them economically valuable. Such species include many large mammals like African elephants, tigers, and rhinoceros. [traded for their tusks, skins, and horns respectively].Less well-known targets of poaching include the harvest of protected plants and animals for souvenirs, food, skins, pets, and more; Because poachers tend to target threatened and endangered species, poaching causes already small populations to decline 

Culling

Culling is the deliberate and selective killing of wildlife by governments for various purposes. An example of this is shark culling, in which "shark control" programs in Queensland and New South Wales (in Australia) have killed thousands of sharks, as well as turtles, dolphins, whales, and other marine life. The Queensland "shark control" program alone has killed about 50,000 sharks — it has also killed more than 84,000 marine animals. There are also examples of population culling in the United States, such as bison in Montana and swans, geese, and deer in New York and other places.

Pollution

A wide range of pollutants negatively impact wildlife health. For some pollutants, simple exposure is enough to do damage (e.g. pesticides). For others, its through inhaling (e.g. air pollutants) or ingesting it (e.g. toxic metals). Pollutants affect different species in different ways so a pollutant that is bad for one might not affect another.
