Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2014-02-25
Assessor(s): Muñoz, A., Gonzales, L., Embert, D., Aparicio, J. & Aguayo, R.

Justification:
Eunectes beniensis has been assessed as Least Concern, due to its large estimated extent of occurrence of more than 45,000 km². The area of South America in which this species occurs is sparsely populated and relatively untouched and underdeveloped. However, some threats to this species exist as it is hunted for its skin and sometimes persecuted. In addition, the species occurs in at least one national park and two departmental reserves.

Population [top]

Population:This species can be locally abundant. The habitat where the species occurs is not changing rapidly as of 2014, suggesting that the population is unlikely to be changing very quickly.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits flooded savannas and Amazonian rain forest (Embert 2009) where it feeds on fish. During dry seasons, individuals may aestivate in damp soils or dry pond beds.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:No

Use and Trade [top]

Use and Trade: This species is used locally for its skin (to make boots, belts, and wallets) and fat for cooking (Cortez et al. 2009). It may also be confused with Eunectes notaeus, which is also harvested, and this may affect this species (D. Embert pers. comm.).

Threats [top]

Major Threat(s): This species is collected for its skin and its use as cooking fat (Cortez et al. 2009). It is also occasionally killed because it feeds on small livestock such as chickens, as well as on dogs and cats (Cortez et al. 2009). As of 2014, there is a proposal to allow international trade in skins. This species occurs in an area of South America which is sparsely populated and relatively untouched and underdeveloped, suggesting that no further threats are affecting this species.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for this species. Most of the distribution of this species is in relatively undisturbed areas (D. Embert pers. comm.). This species occurs in the Kenneth Lee and Humedales del Norte departmental reserves and Bruno Racua National Park. It is included in CITES Appendix II.
