Currently, there is considerable interest in the response of reptile populations to habitat fragmentation and degradation due to urbanization. We surveyed populations of the Common Chuckwalla (Sauromalus ater) in preserves of the Phoenix Mountains and adjacent areas near the Phoenix Metropolitan region during the spring of 2008. Fecal dropping counts were used to assess the current populations in relation to those sampled in 1995. Our results revealed a strong correlation between estimates gathered in 1995 and 2008. Additionally, one intensively sampled site established that, although estimates could vary somewhat in relation to the number of individuals conducting the survey, they were stable over a 13 year period. Overall, survey results suggest that Common Chuckwalla populations are stable in these island preserves in a sea of urban development.
