Proechimys gorgonae Bangs, 1905
|Taxonomic Notes:||Includes P. gorgonae Bangs, 1905 from Gorgona Island as that is considered to be just a form of this species.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Gómez-Laverde, M., Aguilera, M., Boada, C. & Timm, R.|
|Reviewer(s):||McKnight, M. (Global Mammal Assessment Team) & Amori, G. (Small Nonvolant Mammal Red List Authority)|
This species is listed as Least Concern because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it does not appear to be under threat and it is unlikely to be declining anywhere near the rate required to qualify for listing in a threatened category.
|Previously published Red List assessments:||
|Range Description:||This species occurs from southeastern Honduras to southwestern Ecuador (Woods and Kilpatrick 2005). Mostly a lowland species but there are a few unconfirmed records to 1,700 m in Ecuador (C. Boada pers. comm.). It is possible that the species occurs in northwestern Peru (V. Pacheco pers. comm.).|

|Population:||This species is common, often abundant (Reid 1997).|
|Current Population Trend:||Stable|
|Habitat and Ecology:||This large rat is found in lowland evergreen forest primary and second growth. Also occurs in deciduous forest, where it favors riparian corridors and low-lying areas. This species is tolerant to some degree of habitat destruction (e.g., partial deforestation and habitat fragmentation).
Nocturnal, mainly terrestrial and solitary. It travels along fallen logs or old walls but does not climb trees. At night it is often seen sitting quietly near buttress roots or logs. It walks slowly and sometimes freezes in a spotlight. This rat may use burrows during the day but often occupies shallow depressions under roosts and hollow logs, or in dense vegetation. The diet consists mainly of fruit and seeds, with lesser amounts of plant material, insects, and fungi. Palm nuts and other large seeds are carried to a sheltered spot to be eaten. Females give birth to 1 to 5 precocious young and may breed 4 times a year (Reid 1997).
|Major Threat(s):||Deforestation is a threat in some parts of its range, although this species is thought to be tolerant to a degree of habitat destruction or alteration (M. Gómez-Laverde pers. comm.).|
|Conservation Actions:||This species occurs in several protected areas. No conservation measures are needed for this species.|
