Mukurthi National Park is a high-altitude protected area located in the Nilgiri Hills of Tamil Nadu. It forms part of the Nilgiri Biosphere Reserve and is one of the most important habitats of the Nilgiri tahr, an endangered mountain ungulate of the Western Ghats.
The park is significant because it protects the rare shola-grassland ecosystem, a natural mosaic of montane evergreen forest patches and rolling high-altitude grasslands.
Location and Landscape
Mukurthi National Park is located in the western part of the Nilgiris, near Ooty, in Tamil Nadu.
Key facts:
- State: Tamil Nadu
- District: Nilgiris
- Part of: Nilgiri Biosphere Reserve
- Ecosystem: shola-grassland
- Important species: Nilgiri tahr
- Nearby areas: Ooty, Avalanche, Upper Bhavani, Kerala border landscape
The park lies at high elevation and has a cool montane climate. Its landscape includes rolling grasslands, shola forest patches, rocky slopes, valleys and small streams.
The shola forests are usually found in sheltered valleys, while the grasslands dominate exposed hill slopes and plateaus. This pattern is natural and should not be treated as degraded forest.
Habitat and Biodiversity
Mukurthi is one of the best examples of the southern Western Ghats montane ecosystem.
Its main habitats include:
- montane grasslands
- shola forest patches
- rocky cliffs
- high-altitude valleys
- stream-fed wetlands
- cold hill slopes
The park is especially important for the Nilgiri tahr, which depends on open montane grasslands and rocky terrain.
Other species associated with the park include:
- Nilgiri marten
- Nilgiri langur
- leopard
- sambar
- barking deer
- wild dog
- black-and-orange flycatcher
- Nilgiri pipit
- laughingthrush species
- endemic frogs and reptiles
Mukurthi is also rich in endemic plants, especially grasses, orchids, balsams and shola tree species adapted to cool and moist montane conditions.
Hydrological Importance
Mukurthi is an important catchment area in the Nilgiri Hills.
The park and its surrounding highlands feed several streams linked with the Bhavani and Moyar river systems, which are part of the larger Cauvery basin.
Important nearby water systems include:
- Mukurthi Lake
- Pykara system
- Upper Bhavani region
- Avalanche region
- Kundah catchments
The shola-grassland ecosystem plays an important role in regulating stream flow. Grasslands absorb rainfall and release it slowly, while shola forests help maintain moisture in valleys.
This makes Mukurthi important not only for wildlife, but also for downstream water availability in western Tamil Nadu.
Specific Concerns
The main concern in Mukurthi is the degradation of native grasslands due to exotic plantations and invasive species.
Historically, many high-altitude grasslands of the Nilgiris were planted with:
- wattle
- eucalyptus
- pine
These exotic species altered the natural shola-grassland balance and reduced habitat for species such as the Nilgiri tahr and Nilgiri pipit.
Other concerns include:
- spread of invasive wattle into grasslands
- pressure on shola patches
- fire management issues
- tourism pressure in surrounding Nilgiri landscapes
- climate warming affecting high-altitude species
- fragmentation of grassland habitats
- slope instability in disturbed areas
The park’s conservation challenge is not simply forest protection. It is the protection and restoration of native montane grasslands along with shola forests.
Conclusion
Mukurthi National Park is one of India’s most important high-altitude protected areas for the shola-grassland ecosystem.
Its importance lies in its role as a habitat for the Nilgiri tahr, its endemic biodiversity and its function as a water source region in the Nilgiri Hills.
The key conservation priority is the restoration and protection of native grasslands from invasive species such as wattle, while maintaining the natural shola forest patches that define this ecosystem.
