|Population:||Salvador and Fernandez (2008) studied the population dynamics of this species between March 2004 and June 2005 using monthly capture-mark-recapture sampling methods and radio telemetry. Over 5,530 trap-nights, there were 665 captures of 141 individuals. The minimum population was 24, and maximum population was 60. The population had a high and stable density, stable age structure with mostly adults, small home ranges, and high rates of survival. The total population is estimated at 42 (Lacher 2016).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Feeds mainly on grasses. Reproduction is year-round with litter sizes from one to two young which are born highly precocial. Home ranges were found to be 0.05-0.35 ha (Lacher 2016). |
|Major Threat(s):||People have free access to the island and protected area enforcement is not strict. The hunting of this rodent is presumed a threat.|
|Conservation Actions:||This rodent occurs in Serra do Tabuleiro State Park which may receive funds from the Global Environment Facility (GEF) for the conservation of biodiversity and ecosystem rehabilitation. C. intermedia habitat has been designated a Preservation Zone, and all entry is prohibited (Cherem et al., 1999). This park is unmanaged and the park status and entry prohibition are not enforced.|
