Abstract

To determine the current status of beavers {Castor canadensis) in Valle de Mexicali, Mexico, we surveyed the area in late 1995 and early 1996. We found evidence of current presence of beavers at 20 sites; 1 1 additional sites had evi- dence of past use. Most sites were along the Rio Colorado. Population levels of beavers in the area are highly variable and depend on extraordinary water releases through the Rio Colorado.
