Appendix D<br />

Species Accounts<br />

Model Results<br />

Figure D-15 in Appendix D shows the modeled potential habitat for the western<br />

burrowing owl within the study area. Suitable habitat is spread widely<br />

throughout the northern portion <strong>of</strong> the area. Some suitable habitat in<br />

developed areas may not show up in the output because it cannot be<br />

distinguished at this mapping resolution. These are typically small vacant lots or<br />

the margins <strong>of</strong> other land cover types. Most known occurrences fall within<br />

modeled habitat, but the range <strong>of</strong> the suitable habitat is large, and many areas<br />

that the model indicates as suitable have no owl occurrences. In all cases site<br />

specific conditions will dictate whether burrowing owls could be present.<br />

Protocol level nesting surveys are recommended to determine if burrowing owls<br />

are breeding on a site and how many owls the site supports. Other parameters<br />

that the model was not able to capture may be driving burrowing owl<br />

occurrence such as prey abundance.<br />
