Geography

The North Western Ghats moist deciduous forests lies in the northern portion of the Western Ghats (Sahyadri) range. It extends from southeastern Gujarat through Dadra and Nagar Haveli, Maharashtra, Goa, and Karnataka. It covers the eastern and western slopes of the range between 250 and 1000 meters elevation, and surrounds the North Western Ghats montane rain forests ecoregion, which lies above 1000 meters elevation. The ecoregion has an area of 48,200 square kilometers (18,600 sq mi). It is bounded on the west by the Malabar Coast moist forests ecoregion, which lies between the 250 meter elevation and the Arabian Sea. At its northern end, the ecoregion extends to the Narmada River, and borders the Khathiar-Gir dry deciduous forests to the northwest and the Narmada Valley dry deciduous forests to the northeast. The Wayanad forests at the southern end of the ecoregion mark the transition to the South Western Ghats moist deciduous forests further the south.

To the east, in the dry rain shadow of the Ghats, are the Deccan thorn scrub forests and the South Deccan Plateau dry deciduous forests ecoregions, which cover the Ghats' eastern foothills and the Deccan Plateau. [2]

Protected areas

A 2017 assessment found that 2,375 km², or 5%, of the ecoregion was in protected areas. Another 15% is forested but outside protected areas. [3] A 1997 assessment identified thirteen protected areas in the ecoregion, with a combined area of approximately 2,200 km². [4]

Western Ghats Mountain range along the western coast of India

The Western Ghats or the Sahyadri Mountain range is a mountain range that covers an area of 160,000 km2 (62,000 sq mi) in a stretch of 1,600 km (990 mi) parallel to the western coast of the Indian peninsula, traversing the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu. It is a UNESCO World Heritage Site and is one of the eight biodiversity hotspots in the world. It is sometimes called the Great Escarpment of India. It contains a very large proportion of the country's flora and fauna, many of which are endemic to this region. According to UNESCO, the Western Ghats are older than the Himalayas. They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau and separates the plateau from a narrow coastal plain called Konkan along the Arabian Sea. A total of 39 areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty in Kerala, ten in Karnataka, six in Tamil Nadu and four in Maharashtra.

Deccan thorn scrub forests Ecoregion of India and Sri Lanka

The Deccan thorn scrub forests are a xeric shrubland ecoregion of south India and northern Sri Lanka. Historically this area was covered by tropical dry deciduous forest, but this only remains in isolated fragments. The vegetation now consists of mainly of southern tropical thorn scrub type forests. These consist of open woodland with thorny trees with short trunks and low, branching crowns; spiny and xerophytic shrubs; and dry grassland. This is the habitat of the great Indian bustard and blackbuck, though these and other animals are declining in numbers; this area was at one time home to large numbers of elephants and tigers. Almost 350 species of bird have been recorded here. The remaining natural habitat is threatened by overgrazing and invasive weeds, but there are a number of small protected areas which provide a haven for the wildlife. Trees in these forests have adapted to not require much water.

Geography of South India

The Geography of South India comprises the diverse topological and climatic patterns of South India. South India is a peninsula in the shape of a vast inverted triangle, bounded on the west by the Arabian Sea, on the east by the Bay of Bengal and on the north by the Vindhya and Satpura ranges.

Sahyadri Tiger Reserve is a reserve in the state of Maharashtra, created by the Indian government in 2008. Located in the Sahyadri Ranges of the Western Ghats of Maharashtra, it is part of the ecoregions of North Western Ghats moist deciduous forests and North Western Ghats montane rain forests. These ranges form a common boundary between Maharashtra, Karnataka and Goa, and constitute rich evergreen, semi-evergreen and moist deciduous forests. The area is spread over the four districts of Satara, Sangli, Kolhapur and Ratnagiri.
