Abstract
The beaver (Castor canadensis) inhabits a riparian ecosystem surrounded by grasslands, desert thickets and mountain ranges in the so-called Sky Islands. In the period from December 2015 to November 2016, monitoring was carried out to determine relative abundance by photo trapping and density using the direct observation method. We identified five sites with presence of the species. The first data of relative abundance and density for the area was reported. This work represents a joint effort for beaver conservation among civil society organizations, academics and government agencies; this species is considered endangered in Mexico.
