A geographic, climatic, or biological area known as a faunal region is one that is home to a certain group of animal species or communities.Also known as a zoogeographic region. With 92,037 different species in its flora, India boasts a wide range of life forms, including 61,375 different insect species. The number of species thought to still be discovered in India alone is thought to be nearly two times that amount. Species that live there or traits that they share with other species that live there can both serve as descriptors for faunal regions. The scale of faunal regions is often substantially smaller than that of biogeographic domains.
The Himalayan area, the Indo-Gangetic Plain, the Deccan Plateau, the Arabian Peninsula, and the Indian Ocean are the six faunal regions that make up India. A geographic, climatic, or biological area known as a faunal region is one that is home to a certain group of animal species or communities. the Western Ghats, the Eastern Ghats, and the Thar Desert. These areas are distinct from one another because they each have their own specific collection of species and communities.
The loss of flora and fauna is attributed to a variety of factors, including the destruction of habitat owing to increased agricultural activity, over-exploitation of resources, pollution, toxic pollution introduced into the environment, epidemics, floods, droughts, and storms. A significant number of butterflies, moths, and beetles, as well as more than 39 species of mammals, 72 species of birds, 17 species of reptiles, three species of amphibians, two species of fish, and a vast number of other insects are categorised as vulnerable or endangered. These regions are distinct from one another because each has a distinctive collection of species and communities.
Faunal regions are used to differentiate different areas and to identify areas of conservation importance.
