Long Tailed Marmot
Why in News?
The Long-tailed Marmot (Marmota caudata) has appeared in recent news due to increasing human–wildlife interactions along the Amarnath Yatra pilgrimage route in Jammu & Kashmir, due to major ecological concerns along high-altitude trekking routes.
Taxonomy & General Profile
- Family: It belongs to the Sciuridae (squirrel) family and is a large species of ground squirrel.
- Anatomy: They possess a robust, compact body built to store vast fat reserves for survival.
- Long Tail: Unlike other marmots, its tail is significantly longer, measuring nearly half its overall body length.
- Fur Coat: Their dorsal parts feature vibrant golden-yellow to deep orange fur.
- Markings: They sport a distinctive black "saddle patch" running down the back, a black snout, and dark rings around their eyes.
- Tail Tip: The major portion of their long tail tip is prominently black.
Habitat & Distribution
- Global Range: Distributed across the high altitudes of Central and South Asia, including Kyrgyzstan, Tajikistan, Kazakhstan, Afghanistan, Pakistan, China, and India.
- Indian Presence: In India, they are exclusively found in the alpine zones of Jammu & Kashmir and Ladakh.
- Altitude: They thrive strictly at elevations ranging between 3,200 to 4,850 metres above sea level.
- Terrain: They inhabit open meadows, alpine grasslands, rocky slopes, and inland mountain cliffs.
Behaviour & Diet
- Social Structure: They are highly social, diurnal (active during the day) mammals that live together in tight-knit groups.
- Diet: Strictly herbivorous, feeding primarily on alpine grasses, roots, and small seasonal plants.
- Burrowing: They are master diggers, constructing deep burrow networks that inherit generationally to stay safe from predators.
- Extreme Hibernation: They hibernate for an extensive period from September to April/May. To survive, they slow their heart rate down from 80 to just 5 beats per minute.
Ecological Importance & Conservation Status
- Soil Health: Their extensive burrowing naturally aerates high-altitude soil, mixing nutrients and encouraging plant propagation.
- Prey Base: They serve as a vital food source for endangered apex predators of the Trans-Himalayas, including the Snow Leopard, Himalayan Brown Bear, Red Fox, and Golden Eagle.
- IUCN Red List: Classified as Least Concern.
- CITES Protection: Listed under Appendix III, regulating its international trade.
- Primary Threats: Vulnerable to climate change (melting glaciers reducing forage), habitat destruction, attack by free-ranging feral dogs, and disturbance from tourist traffic.
