Change in Nesting Habitat.

<p>Change in relative predicted probability surface between the pre- and post-mitigation nesting habitat models for greater sage-grouse in the Powder River Basin, Wyoming, U.S.A. Values range from -3 (black) to +3 (dark green) and represent the change in bin classification between the two models from pre-mitigation nesting habitat to post-mitigation nesting habitat. Nest locations used in the pre-mitigation model development (2004–2007) are indicated by the blue circles and the nest locations used in the post-mitigation model development (2008–2011) are indicated by the yellow circles. Unmitigated well locations are indicated by black circles. Mitigated wells are indicated by purple circles.
