|Scientific Name:||Choloepus hoffmanni|

|Taxonomic Notes:||Five subspecies are recognized by Gardner and Naples (2007).|
|Red List Category & Criteria:||Least Concern ver 3.1|

Choloepus hoffmanni is listed as Least Concern in view of its wide distribution, presumed large population, its occurrence in a number of protected areas, its tolerance of a degree of habitat modification, and because it is unlikely to be declining fast enough to qualify for listing in a threatened category. However, because of ongoing deforestation, the northern population (nominate subspecies) of this species could potentially be assessed as Near Threatened.
Choloepus hoffmanni has two disjunct populations. The northernmost population ranges from Nicaragua south into western Venezuela. The southern population is found from north-central Peru through extreme western Brazil (south-western Amazonas and probably Acre states) to central Bolivia. There is a doubtful, outlying record for this species from the Rio Aripuanã, Mato Grosso state, Brazil (Fonseca and Aguiar 2004). Its range within Brazil is unclear, and further surveys are needed.
This species ranges from sea level to 3,300 m Asl in Costa Rica; up to 1,925 m Asl in Panama; and up to 1,150 m Asl in the southern Andes of Venezuela. In Colombia, the species is found in the biogeographical regions of the Andean zone, Caribbean and Chocó, more specifically in the departments of Cauca, Chocó, Cundinamarca, Nariño, Quindío, Sucre, Valle del Cauca, and Santanderes from sea level up to 3,200 m Asl (Alberico et al. 2000, Moreno 2003, Morales-Jiménez et al. 2004, Acevedo and Sanchez 2007).

Choloepus hoffmanni occurs at densities of 1.05 animals per hectare on Barro Colorado Island, Panama (Montgomery and Sunquist 1975). It has been found at densities of 0.3 to 1.5 animals per hectare in the Andean region of Colombia, while densities in the lowlands of northern Colombia were 0.2 to 0.83 individuals per hectare (Alvarez 2004, Acevedo and Sanchez 2007).
|Habitat and Ecology:||Choloepus hoffmanni is largely found in lowland and montane tropical forest, both deciduous and mixed-deciduous. In Central America, it occurs in evergreen and semi-deciduous tropical moist forest, as well as in secondary forest, but it is rare or absent in lowland dry forest. In Costa Rica, it is able to use cocoa plantations (Theobroma cacao) as habitat (Vaughan et al. 2007, Peery and Pauli 2012) and frequently ventures into relatively open pastures in search of isolated feeding trees (Vaughan et al. 2007). It can also occur in dry grassland with thorny shrubs and trees (Nicaragua, Genoways and Timm 2003). These sloths are rather solitary. In cocoa farms of Costa Rica, the mating system involves a mixture of polygyny with promiscuity, the sex ratio is female-biased and male home ranges vary from 1.1 to 139.5 ha (Peery and Pauli 2012). Their herbivore-omnivore diet consists mainly of leaves, fruits and sap of some trees.|
|Use and Trade:||In some parts of its range, C. hoffmanni is hunted for food and to be sold as a pet to tourists.|
|Major Threat(s):||It appears that there are no major threats to C. hoffmanni at the global level. Nevertheless, subpopulations in the northwestern part of its range, especially in Colombia and Central America, are declining due to severe habitat degradation and fragmentation. Furthermore, they are hunted by indigenous communities. Wild-caught individuals, especially offspring, are sold as pets to tourists in Colombia (Moreno and Plese 2006). This illegal trade is increasing and represents a cause of concern due to its impact on the wild population.|
|Conservation Actions:||Choloepus hoffmanni is present in many protected areas. It is included in CITES Appendix III for Costa Rica. Further research is needed to establish whether there are taxonomic differences between the two disjunct populations.|
