Areas of highest landscape integrity have the lowest human footprint (e.g., natural land-covers, low housing density, and minimum roads).
Composite landscape integrity linkage map which combines four sensitivity models. Cost values indicate relative ease of movement within each linkage.

The precedent: California had just finished their statewide analysis.
It required painstaking ID of which core area pairs to connect.
Linkage Mapper
After that, corridor mapping took months and tens of thousands of dollars in analyst time.

• Use WWHCWG linkage models as cost‐surface for testing;
• Compare degree of correspondence between WWHCWG models and genetically derived models;
• Evaluate how well occurrence data matches predicted HCA and linkage habitat from WWHCWG models.

Communications to build support for connectivity conservation
The goal of the communications and implementation subgroup:
“to provide complementary products to our scientific analysis that will inform and guide communications and implementation of our work, while facilitating effective internal and external communications.”

3. How the GNLCC can/is supporting this effort, and the value towards achieving collective vision among diverse agencies and organizations• Big picture needs: consistent data sets, collaboration sites
such as data portel, GIS tools, communicating and sharing across state and national borders
• Connectivity group includes ambitious work plan, we seek to accomplish this work in ways that can be shared with and by the GNLCC. • Capacity and funding for all aspects of work very
challenging .• GNLCC funding is hugely important for the group’s
work
