Webinar: Mapping basic requirements for greater sage-grouse

Event Type: 
GNLCC Webinar
Date and Time: 
Jan 28, 2014 (All day)

Time: 1pm Mountain

This is the second of eight webinars offered by the Sage Steppe Partner Forum. The forum aims to share knowledge around Greater Sage-grouse, sagebrush habitat, and management across the species's historic range. Sponsors of the webinar series are the Great Northern, Southern Rockies, Plains and Prairie Potholes, and Great Basin Landscape Conservation Cooperatives.

Presenter: Steve Knick, USGS Research Wildlife Biologist

Description: Mapping broad regional distributions of a species can be limited by availability of consistent data. Statistical models also face trade-offs between model fit and prediction: results derived from local studies often fail when applied to new environments outside the original inference space. We used a method first described in 1901 to identify basic requirements of greater sage-grouse (food, cover, space, and water only a little more complicated). We mapped an index of similarity to identify areas that met this basic set of requirements.  Then, we created maps of potential corridors among delineated populations under the assumption that resistance to dispersal movements was inversely related to a location’s minimum chacteristics.  When coupled with range-wide information on gene flow currently being developed, we will have a powerful understanding of connectivity among populations and likely corridors used by dispersers.
