|Scientific Name:||Sigmodontomys alfari J.A. Allen, 1897|
|Taxonomic Notes:||Also known as Orzomys alfari.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Anderson, R.P., Tirira, D., Samudio, R. & Timm, R.|
This species is listed as Least Concern in view of its wide distribution, presumed large population, occurrence in a number of protected areas, and because it does not appear to be under threat and is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.
|Previously published Red List assessments:|
|Range Description:||This species is found from eastern Honduras to Panama, and from central and west Colombia to northwest Venezuela and northwest Ecuador (Musser and Carleton 2005).|

|Population:||This species is locally common. However, it is generally rare north of Panama (Reid 1997) and in Venezuela it is not common (Lord 1999). In Colombia, this species is known from large surveys, but is poorly known in Venezuela where habitat is very disturbed (B. Rivas and R. P. Anderson pers. comm.).|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This rodent is poorly known. It lives in wet lowland forest, secondary forest, cane fields, marshes, or cultivated areas near water. It swims well and is probably nocturnal (Reid 1997; Lord 1999). It seldom climbs, and it feeds on seeds and vegetation.|
|Generation Length (years):||1-2|
|Major Threat(s):||There does not appear to be any major threats to this species.|
|Conservation Actions:||It occurs in several protected areas. No conservation measures are needed for this species.|
|Errata reason:||This errata assessment has been created because the map was accidentally left out of the version published previously.|
