Assessment Information [top]

Red List Category & Criteria:

Vulnerable B1ab(i,ii,iii,iv)+2ab(i,ii,iii,iv) ver 3.1

Year Published:

2010

Assessor/s:

Tirira, D. & Boada, C.

Reviewer/s:

Amori, G. & Schipper, J.

Justification:
This species is listed as Vulnerable, because its extent of occurrence is less than 20,000 km² and its area of occupancy is less than 2,000 km²; its distribution is severely fragmented. There is a continuing decline in range (area of occupancy and extent of occurrence) and habitat quality due to past water pollution events, which make this species extremely susceptible to such threats in the future, especially if it is semi-aquatic. Further research is necessary to understand basic ecology, distribution, and threats. This species is not known to occur in any protected areas.

History:

2008	–	Vulnerable (IUCN 2008)
1996	–	Endangered

Population [top]

Population:	This is a rare species (Tirira in prep.). In the Papallacta area (Napo Province), Voss (2003) collected 12 specimens between 1978 and 1980. In the same area, C. Boada (pers. comm.) in 2002 did not collect any specimens over a nine day period working with 400 traps.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	This rodent is poorly known. It inhabits along swift, cold, turbulent streams bordered by subalpine rainforest or grassy paramo (Voss 1988). It may be nocturnal.
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	The major threats are habitat loss and water pollution. In 2003, the Papallacta Lake was seriously contaminated by a huge oil spill. There is no information on how this affected wildlife (C. Boada pers. comm.).
