In April 2020 the Mammal Index reported that there had been a decline of more than a third of threatened mammal numbers in the 20 years between 1995 and 2016, but the data also show that targeted conservation efforts are working. The Threatened Mammal Index "is compiled from more than 400,000 individual surveys, and contains population trends for 57 of Australia's threatened or near-threatened terrestrial and marine mammal species". Individual states and territories of Australia are bound under

Threatened species are also referred to as a red-listed species, as they are listed in the IUCN Red List of Threatened Species . Subspecies , populations and stocks may also be classified as threatened. The Commonwealth of Australia (federal government) has legislation for categorising and protecting endangered species, namely

Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation , a mathematical measure of biomass related to population growth rate . This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity. The International Union for Conservation of Nature (IUCN)

Ghat , a term used in the Indian subcontinent , depending on the context, could either refer to a range of stepped hills such as the Eastern Ghats and Western Ghats, or a series of steps leading down to a body of water or wharf . As per linguist Thomas Burrow , the word Ghat was derived from similar words used in various Dravidian languages such as kattu (mountain side, ridge, or dam) in Tamil , katte (dam), gatta (mountain), and gattu (bank or shore) in Kannada , and katta (dam), and gatte (shore or embankment) in Telugu .

The Western Ghats form one of the major watersheds of India, feeding many perennial rivers. These major river systems drain almost 40% of the land area of the country. The major river systems originating in

1612-442: The IUCN. Although threatened and vulnerable may be used interchangeably when discussing IUCN categories, the term threatened is generally used to refer to the three categories (critically endangered, endangered, and vulnerable), while vulnerable is used to refer to the least at risk of those three categories. They may be used interchangeably in most contexts however, as all vulnerable species are threatened species ( vulnerable

1664-563: The Western Ghats are the Godavari , Kaveri , and Krishna . Most rivers flow eastwards towards the Bay of Bengal owing to the steeper gradient moving from east to west, and many smaller streams drain the region, often carrying a large volume of water during the monsoon months. The streams and rivers give rise to numerous waterfalls in the region. The rivers have been dammed for hydroelectric and irrigation purposes, with major reservoirs spread across

1768-852: The Western Ghats were severely fragmented due to clear-felling for plantations. The introduction of non-native species threatened the rare endemic species and habitat specialists, which depleted faster than other species. Complex and species-rich habitats like the tropical rainforests are much more adversely affected than other habitats. The primary threats to fauna were not only from habitat loss , but also from overexploitation , illicit grazing , mining , poaching , and introduced species . The Government of India has established many protected areas , including two biosphere reserves , 13 national parks to restrict human access, several wildlife sanctuaries to protect specific endangered species, and many reserve forests .

Among the threatened freshwater molluscs are the mussel species Pseudomulleria dalyi , which is a Gondwanan relict, and the snail Cremnoconchus , which is restricted to the spray zone of waterfalls. According to the IUCN, four species of freshwater molluscs are considered endangered and three are vulnerable. An additional 19 species are considered data deficient. There are roughly 6,000 insect species. Of
1872-443: The Western Ghats. Historically, the Western Ghats were covered in dense forests. which formed the natural habitat for wildlife along with the native tribal people . Its inaccessibility made it difficult for people from the plains to cultivate the land and build settlements. After the establishment of British colonial rule in the region, large swathes of territory were cleared for agricultural plantations and timber. The forests in

In August 2011, the Western Ghats Ecology Expert Panel (WGEEP), appointed by the Union Ministry of Environment and Forests to assess the biodiversity and environmental issues of the Western Ghats, designated the entire region as an Ecologically Sensitive Area (ESA) and assigned three levels of Ecological Sensitivity to its different regions. Subsequent committees formed have recommended various suggestions to protect

The Western Ghats form one of the major watersheds of India, feeding many perennial river systems that drain almost 40% of the land area of the country. Because of the higher elevation of the Deccan plateau on the west, most rivers flow from eastwards towards the Bay of Bengal , resulting in chiselled eastern slopes and steeper western slopes facing
2080-555: The indigenous species, 2,253 species are endemic to India and of them, 1,273 species are exclusively confined to the Western Ghats. 645 tree species were recorded with a high endemic ratio of 56%.

Geologic evidence indicates that they were formed during the break-up of the super-continent of Gondwana . After the break-up, the Deccan plateau was formed by basalt rocks, which caused the western side to rise at an elevation. Geophysical evidence indicates that
2288-438: The mountains came along the west coast of India somewhere in the late Jurassic and early Cretaceous periods when India separated from the African continent. Several faults triggered the formation of Western Ghats, then interspersed with valleys and river gorges. Because of the elevation of the Deccan plateau on the west, most rivers flow from west to east, resulting in chiselled eastern slopes and steeper western slopes facing

A total of 77 species of freshwater molluscs (52 gastropods and 25 bivalves ) have been recorded from
2496-416: The region. The Western Ghats play an important role in determining the climate and seasons in India. During the dry summer months of April – May, heat builds up on the land, which draws air from the sea. The air, which picks up moisture along the way and flows eastward from the Arabian Sea, is blocked by the Western Ghats. The rising air cools and brings about orographic precipitation along
