Conservation planning aims to optimize outcomes for select species or ecosystems by directing resources toward high-return sites. The possibility that local benefits might be increased by directing resources beyond the focal area is rarely considered. We present a case study of restoring river connectivity for migratory fish of the Great Lakes Basin by removing dams and road crossings within municipal jurisdictions versus their broader watersheds. We found that greater river connectivity could often be achieved by considering both intra-jurisdictional and extra-jurisdictional barriers. Focusing on jurisdictional barriers alone generally forfeited <20 (median = 0%) of habitat gains for those who value solely habitat...

On-a-wing and a (GIS) Layer: Prioritizing migratory bird habitat along Great Lakes shoreline
The Nature Conservancy - Great Lakes Program is leading the development of a scalable (Great Lakes wide, individual lake basin, to coastal reach within a lake basin) rule-based spatial model for ranking the relative importance of coastal lands and waters as habitat for migrating birds. Results will guide conservation actions including land acquisition, land and water management and restoration, and development of wind energy facilities. Specifically, the team will: 1) refine, create and integrate migratory bird stopover habitat models which depict the distribution of potential stopover sites along or near the shorelines of Lakes Michigan, Huron, Erie, and Ontario; and, 2) develop an online portal that will deliver...

Re-establishing ecological connectivity between the Great Lakes and their tributaries: Prioritization in a complex system
Ecological connectivity between the Great Lakes and their tributaries is widely impaired, and many agencies and organizations are currently investing in restoring these connections to enhance target fish and wildlife populations. To assist in targeting these investments, we have been developing spatial data on the location and attributes of barriers (dams and road-stream crossings) and fish breeding habitat throughout the Great Lakes basin to analyze the optimum strategy for enhancing connectivity and restoring fish migrations. The proposed work will result in guidance for barrier restoration at scales from individual watersheds to the entire basin, refine methodologies for spatial analysis of barriers, and provide...

Leveraging Genomic Data to Increase Adaptive Potential and Inform Management Action for the Endangered Mitchell's Satyr Butterfly Under Climate Change
Habitat loss is splitting the world’s plant and animal populations into smaller, more isolated fragments. At the same time, many organisms must also withstand rapid and stressful changes to their environment. Combined, these factors can increase extinction risk. A possible escape from extinction is through adaptation. Yet, small populations with low genetic diversity may be unable to adapt in time to keep pace with environmental change. One strategy to mitigate these problems is to move individuals from larger, more resilient populations with higher genetic variation into small, declining populations to induce 'genetic rescue'. This project will use cutting-edge genomic tools to evaluate the potential for genetic...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
