Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-02-08

This species is listed as Least Concern based on the fact that it is locally common and even considered a pest species, it does well in secondary forests and gardens. Genetic studies have confirmed that this species still has a high genetic variability. Future habitat destruction and conversion may lead to this species listed as Vulnerable based on its small area of occupancy.

Population [top]

Population:This species is locally common (Heaney et al. 1998, J. C. Gonzalez pers. comm.). It is abundant on Calauit mainly due to a safari ranch that has giraffes, zebras, antelope.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species was formerly found in primary lowland evergreen forests, a habitat that is now absent on these islands. Today, it occurs in secondary forests, and occasionally in gardens where it is considered a pest species. It has not been trapped in grassland (L. Heaney pers. comm., J. C. Gonzalez pers. comm.).
Generation Length (years):3-4

Threats [top]

Major Threat(s): This species is hunted at times, because it can be an agricultural pest, but this is unlikely to be a major threat to the species. However, there is ongoing habitat destruction in some places due to conversion of forests to slash and burn areas that the squirrels can not tolerate (J. C. Gonzalez and P. Widmann pers. comm.).

Conservation Actions [top]

Conservation Actions: The species occurs in a protected area on Caluit island.
