Scientific Name: Isthmomys flavidus

Common Name(s):
English Yellow Isthmus Rat

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Reid, F., Woodman, N., Timm, R. Samudio, R. & Pino, J.
Reviewer(s): McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)
Justification:
Listed as Near Threatened because although its extent of occurrence is less than 20,000 km2, it occurs in several protected areas and the extent and quality of its habitat may be declining only in parts of its range. This species is restricted to mature forest and it appears to no longer occur in one previously known location. This makes it close to qualifying for Vulnerable under the B1 criterion if the decline in known locations continues and if the distribution becomes severely fragmented or restricted to less than 6 locations.
