Assessment Information [top]

Red List Category & Criteria: Least Concern (Regional assessment) ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Kryštufek, B. & Mitsain, G.
Reviewer(s): Amori, G. (Small Nonvolant Mammal Red List Authority) & Temple, H. (Global Mammal Assessment Team)
Justification:
A common species within its range, with no major threats known. Appears to be tolerant of habitat disturbance. Consequently it is assessed as Least Concern.

If one of the races within this species is eventually raised to species level its restricted range may merit a threatened listing. However, more work is necessary to determine its taxonomic status.
