In the heart of the Western Ghats, a critical global biodiversity hotspot in Maharashtra, a rare low-altitude basalt plateau has been unearthed. This monumental discovery garners significant attention for a multitude of reasons. Primarily, it offers fresh insights into the study of climate change impacts on species survival. Furthermore, it prompts an elevated awareness towards the preservation needs of rock outcrops and their extensive biodiversity value in a worldwide perspective.
Significant Discoveries About the Plateau
The Low-Altitude Basalt Plateau is distinct in being the fourth plateau classification in the region, following laterites at high and low altitudes and basalt at high altitudes.
A biodiversity survey of the plateau revealed 76 plant and shrub species belonging to 24 different families. This finding holds great importance as the plateau features vegetation similar to the three other rock outcrops, yet concurrently houses unique species. These data provide a distinctive model system enabling comprehensive studies of species interactions under varying environmental conditions.
It should be understood that rock outcrops, owing to their seasonal water availability and limited soil and nutrients, serve as perfect laboratories for studying the impact of climate change on species survival. In essence, plateaus could essentially be a treasure trove of knowledge on how species manage to survive under harsh conditions.
Crucial Information about the Western Ghats
Stretching along the Western Coast of India, the Western Ghats encompasses states including Kerala, Maharashtra, Goa, Gujarat, Tamil Nadu, and Karnataka. The Ghats represent one of four global biodiversity hotspots in India, along with the Himalayas, the Indo-Burma region, and the Sundaland, which includes the Nicobar Islands. Its considerable biodiversity significance has resulted in its recognition as a UNESCO World Heritage Site.
The Ghats play a crucial role in mediating the warm tropical climate of the region by influencing Indian monsoon weather patterns. Acting as a barrier to the rain-laden monsoon winds arriving from the south-west, the Western Ghats are home to tropical evergreen forests and provide shelter to 325 globally threatened species. Plateaus form a dominant landscape feature in the Western Ghats, primarily due to the high prevalence of endemic species they host.
Furthermore, it’s worth noting that the importance of the Western Ghats and its conservation needs have been highlighted in numerous reports, including the ‘Gadgil Committee Report’ and the ‘Kasturirangan Committee Report’. These significant documents bring into focus the need for robust initiatives to protect and preserve this unique biodiversity hotspot.
Recapitulation of UPSC Civil Services Examination Questions
In retrospect, questions related to the Western Ghats have frequently surfaced in UPSC Civil Services examinations. For instance, in 2017, a question required the correct identification of states where the Himalayas and Western Ghats spread over, and another in 2016 enquired about the subject matter of the ‘Gadgil Committee Report’ and ‘Kasturirangan Committee Report’. Such instances further underline the importance of a thorough understanding of the Western Ghats in the broader scheme of things.
