Grizzled Giant Squirrel

April 19, 2025

The Villupuram Forest Division is initiating a population study of the grizzled giant squirrel in the Pakkamalai and Gangavaram hills. This area is rich in biodiversity and is crucial for the conservation of this endangered species. The study aims to gather baseline data to formulate effective conservation strategies. The grizzled giant squirrel, listed under Schedule I of the Wildlife Protection Act, 1972, is known for its unique habitat preferences and ecological role.

Species Overview

The grizzled giant squirrel (Ratufa macroura) is the smallest member of the giant squirrel family.
It inhabits riparian forests in Southern India and Sri Lanka.
Its distinctive greyish-brown body features white flecks, giving it a ‘grizzled’ appearance.
These squirrels are primarily arboreal and are most active during dawn and dusk. They play a vital role in their ecosystem by foraging for fruits, seeds, and bark, which aids in plant dispersal and enhances floral biodiversity.

Habitat and Distribution

Grizzled giant squirrels are typically found in fragmented populations across Southern India. They thrive in the Western Ghats, with notable populations in the Chinnar Wildlife Sanctuary and the Anamalai Tiger Reserve. Their habitat consists of dense forests near rivers, which provide essential resources for foraging and nesting.

Threats to Survival

The primary threat to the grizzled giant squirrel is habitat loss due to deforestation and human encroachment. This loss reduces food availability and nesting sites, which hinders their ability to thrive. The International Union for Conservation of Nature (IUCN) has classified this species as Near Threatened. Additionally, poaching poses risk, further endangering their populations.

Conservation Efforts

The population study is a collaborative effort involving experts and volunteers. Its goal is to assess the current population and understand the ecosystem dynamics affecting the grizzled giant squirrel. The data collected will inform conservation measures and support the long-standing demand to designate the Pakkamalai and Gangavaram hills as a wildlife sanctuary.

Biodiversity Significance

The Pakkamalai and Gangavaram hills are home to a diverse range of flora and fauna. This includes critically endangered species such as the golden gecko and various tropical birds. The area hosts over 3,000 individuals of amphibians and reptiles from numerous families. It is crucial to protect this biodiversity to maintain ecological balance and support the survival of endemic species.
