During a survey of the Jurua River, Brazil, many specimens were trapped in terra firme forests (28 of 57), they were also collected in locally inundated forest, secondary upland forest and abandoned gardens and were especially common in the latter (Patton et al., 2000). In the same survey, out of sampling months August to March, pregnant females were collected only in February and March. All litters comprised two young. Data are too limited to determine whether breeding is largely confined to the wet season or also extends through the dry period. Voss et al. (2001) also presents capture data for three different habitat plots in French Guiana, where the species is found equally in both secondary and primary forest (Voss et al. 2001).

  Lower Risk/least concern

This rodent is abundant in primary forest but absent in secondary forest in French Guiana (F. Catzeflis pers. comm.). It is found in secondary forest in Rio Jurua in western Amazonia (Patton et al., 2000). It is a very abundant species in Tumucumaque National Parque (C. Silva pers. comm.).

Unknown

There are no major threats to this species at this time.

This species occurs in Tumucumaque National Park (C. Silva pers. comm.) and several other protected areas throughout its range.
