Habitat and Ecology [top]

Habitat and Ecology:This largely fossorial species is restricted to chaco-seco (thorn forest) habitats (Meritt 1985). There is little available information on its life history and other biological characteristics. No information exists on the age at first reproduction, longevity, or generation length of this species, neither from wild nor from captive populations. The generation length of another armadillo species, the Nine-banded Armadillo (Dasypus novemcinctus), has been estimated to be 5 years. The generation length for C. chacoensis is suspected to be similar.
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):5

Use and Trade [top]

Use and Trade: This armadillo is hunted to be used as a protein source.

Threats [top]

Major Threat(s): This species is threatened by habitat degradation from agricultural activity, subsistence hunting for food by local people, as well as predation by dogs.

Conservation Actions [top]

Conservation Actions:  This armadillo species has been recorded in several Argentinean national and provincial parks.
