The major cause of the grizzled giant squirrel's endangerment is the rapid loss, fragmentation, and degradation of its natural habitat.
- Deforestation: The expansion of agriculture, logging, and other human activities has led to the clearance of vast areas of the squirrel's forest habitats.
- Forest Fragmentation: As forests are cleared, the remaining forest patches become isolated, reducing the population's genetic diversity and increasing vulnerability to various threats.
Hunting and Poaching:
This squirrel faces hunting pressure for its meat and fur.
- Subsistence Hunting: In some regions, local communities hunt the grizzled giant squirrel for sustenance.
- Illegal Trade: The squirrel is also subject to illegal trade for the pet industry and traditional medicine.
Competition with Invasive Species:
Introduced species, such as the Red-whiskered bulbul, have become significant competitors for food resources and nesting sites, affecting the squirrel's survival and reproduction.
Climate Change:
Changing climate patterns can alter the squirrel's habitat, including the distribution of food sources, potentially impacting its population dynamics.
