There are myriad barriers to aquatic connectivity beyond dams, with culverts at road crossings primary among them. UGA will lead the effort to develop a database of these non-dam blockages and model the likelihood that each is a barrier to fish movement, including mussel hosts. This process, described in more detail below, will result in a GIS point layer with numeric attributes that describe the likelihood that any given crossing is a blockage to fish passage. This data will be incorporated into the dam database to produce a database of all known and potential barriers in the region. This unified database will form the unit of analysis for the subsequent connectivity assessment in which each of the barriers will...

Habitat fragmentation and degradation are considered to be a leading causes of long-term population declines of Northern Bobwhites and many other species of grassland birds, such as Eastern Meadowlark. Research is needed to understand the factors causing habitat loss and fragmentation and to identify the areas that are high-probability candidates for successful restoration so that optimal decisions can be made. For example, uncertainty exists regarding the impacts of energy development activities or climate change that affect significant portions of wildlife populations in the GCP LCC. Furthermore, changing land ownership coupled with woody shrub and exotic grass encroachment have reduced the amount and quality...

This project supports the technical development of a mobile application for identifying and reporting invasive plant species in Alaska. It will result in a portable, digital version of a field guide that can be easily updated and that supports integration of reports into the Alaska Exotic Plants Information Clearinghouse (AKEPIC). Under development for both Android and iOS operating systems, the app has the potential to increase the public’s knowledge of invasive plants, as well an improve opportunities for reporting new occurrences.

Amphibians and reptiles are experiencing severe habitat loss throughout North America; however, this threat to biodiversity can be mitigated by identifying and managing areas that serve a disproportionate role in sustaining herpetofauna. Identification of such areas must take into consideration the dynamic nature of habitat suitability. As climate rapidly changes it is possible that areas currently deemed suitable may no longer be so in the future. To address these needs, we are proposing to generate spatially-explicit data that will (1) identify Priority Amphibian and Reptile Conservation Areas (PARCAs) – those discrete areas most vital to maintaining reptile and amphibian diversity, (2) project regions of current...

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.
