500+ questions on Environment with explanations
📌 Summary:
-
Context: Severe wildfires struck Nilgiris (Parsons Valley, Pykara, Wenlock Downs) and adjoining Mudumalai, Coimbatore, Erode forest divisions; Indian Air Force assistance required
-
Fires are seasonal (Feb-May) but this year's intensity is anomalous: high heat, strong winds, and accumulated invasive biomass
-
Causal chain: (a) Invasive Lantana camara creates dense undergrowth burning hotter and longer; (b) Existing firebreaks failed when winds carried embers across; (c) Steep terrain limits road access for ground teams; (d) Delayed IAF deployment due to bureaucratic coordination gaps
-
Ecological significance: Nilgiris is part of UNESCO World Heritage Western Ghats; home to Mudumalai Tiger Reserve and Nilgiri Biosphere Reserve — among India's most biodiverse zones
-
Key concern: Uncontrolled fires destroy shola forests, grasslands, and critical wildlife corridors linking tiger reserves
-
Solutions proposed: Pre-positioned IAF assets during fire season; Van Suraksha Samitis (community fire-watch); invasive species clearance programmes; ISRO VIIRS satellite monitoring
-
Climate connection: Drier winters, extended fire seasons, increased lightning strikes — all amplifying wildfire risk across Western Ghats
