This species is listed as Least Concern as although it is probably locally threatened as a result of human activity (Nowak, 2005), it is locally common throughout his entire range and occurs in a variety of natural and disturbed habitats.
|Range Description:||This species occurs from southern Veracruz, Mexico, throughout Mesoamerica and south across South American to northern Argentina, occurring throughout except for the high Andes and Caatinga (eastern Brazil).|

|Population:||Eira barbara is one of the most common medium-size predators throughout its range (Emmons and Freer, 1990). Common in Central America (Janzen, 1983; Alston, 1882; Kaufmann and Kaufmann, 1965; Emmons and Freer, 1990; Reid, 1997), Colombia, Guyana, Surinam, French Guiana (Eisenberg, 1989), Venezuela (Handley, 1976), Bolivia (Anderson, 1997), Brazil (except in the caatingas and cerrado; Emmons and Freer, 1990), Paraguay, and northern Argentina (Barquez et al., 1991; Mares et al. 1989; Redford and Eisenberg, 1992). However, was not recorded in the Paraguayan Chaco during a year (1989-1990) of large mammal censuses (Brooks, 1998), despite a taxidermied specimen in the local museum (Brooks, 1991).|
|Habitat and Ecology:||
Eira barbara is a diurnal, sometimes crepuscular species (Reid, 1997), solitary that travels within a big home range (Sunquist et al., 1989). It seems to be a forest species, using both floor and tree habitats. Emmons and Freer (1990) affirms that Tayra inhabits tropical and subtropical forests, secondary rain forests, gallery forests, gardens, plantations, cloud forests, and dry scrub forests. Hall and Dalquest (1963) affirms that it can live near human habitations, crops and other human disturbed habitats. Usually occupies below the 1,200 m, but there are reports up to 2,400 m (Emmons and Freer, 1990; Eisenberg, 1989) and is common at 2,000 m (Gonzalez-Maya pers. comm.).
Diet of Tayras is omnivorouse, including fruits, carrion, small vertebrates, insects, and honey and small vertebrates as marsupials, rodents, iguanids among others (Cabrera and Yepes, 1960; Emmons and Freer, 1990; Galef et al. 1976; Hall and Dalquest, 1963). This species does well in agricultural areas and along the edge of human settlements.
|Major Threat(s):||There is not evidence about trapping or hunting of the species (Emmons and Freer 1990). Schreiber et al. (1989) reported that the range of the tayra has been reduced in portions of Mexico because of the destruction of tropical forests and spread of agriculture.|
|Conservation Actions:||Tayras occur in numerous protected areas. Honduras lists this species under CITES Appendix III.|
