Habitat
This species primarily inhabits coniferous and mixed forests in mountainous regions of western China, at elevations between 2,000 and 4,000 meters. They prefer cool, temperate climates with abundant tall trees for nesting and gliding, avoiding open areas.
Diet
The Groove-toothed flying squirrel mainly eats nuts, seeds, and fruits from trees like pines and oaks, supplemented by insects and buds. They forage nocturnally, gliding between trees to access food sources, and cache excess food in tree hollows for later.
Behavior
These squirrels are nocturnal and arboreal, spending their nights gliding between trees in search of food and retreating to nests in tree cavities during the day. They are typically solitary but may share dens in winter for warmth, and exhibit territorial behavior through scent marking. Gliding distances can reach up to 50 meters, helping them evade predators.
Conservation Status
The IUCN status is Data Deficient due to limited research, but habitat loss from deforestation and climate change poses a potential threat. Population trends are unknown, though fragmentation of montane forests may be impacting their numbers.
