Climate Change, Conservation Planning, and Renewable Energy Development in the Mojave Desert: Renewable energy development in the desert southwest has raised concerns about potential impacts to sensitive biological resources. This research developed analytical approaches, decision support tools, and geospatial data to aid conservation planning for renewable energy development in the California deserts. As a part of the study, a hierarchical logic model was created to map the relative degree of compatibility of new solar energy projects with current biological conservation values. Additionally, species distribution models were produced for 65 animal and plant species of potential conservation significance to the Desert Renewable Energy Conservation Plan process. At the upcoming ESA annual meeting in Baltimore, MD, research geographer Jason Kreitler will highlight how these models were applied to map both historical and projected future habitat suitability. The data and models created in this project support conservation decision-making for offset siting and the potential cumulative impacts of multiple solar energy projects given background climate and land use change. For more information, please contact Jason Kreitler, (208) 426-5217 (firstname.lastname@example.org).

Mapping Extent and Change in Surface Mines within the United States for 2001 to 2006: Until recently, a spatially explicit dataset illustrating the 21st century mining footprint for the conterminous United States did not exist. Through collaboration between the USGS Western Geographic Science Center, USGS Eros Data Center, and SUNY Department of Forest and Natural Resources Management, surface mines within the United States have now been mapped for 2001 and 2006. These maps present a more complete picture of mining in the United States, and can contribute to research concerning the environmental consequences of land use throughout the country. The process is documented in Land Degradation and Development (http://onlinelibrary.wiley.com/doi/10.1002/ldr.2412/abstract). Supplemental spatial data are hosted by USGS (http://landcovertrends.usgs.gov/download/mining.html). (Christopher Soulard, email@example.com, 650-329-4317).

USGS presentation on transboundary wildfire patterns at the 9th Annual International Association for Landscape Ecology (IALE) World Congress: Western Geographic Science Center researcher Miguel Villarreal will present research conducted in partnership with researchers at Instituto Politécnico Nacional in Durango, Mexico that examines recent patterns of wildfire severity in 39 mountain ranges separated by the US-Mexico border and managed under contrasting fire policies. Results show that mountains in the US had more fires, more burned area, and increasing severity over time when compared to mountain ranges in Mexico. The information from this research can be used to guide forest restoration and fire management strategies in both countries. The presentation is part of the IALE fire ecology symposium "Opportunities and constraints in the restoration and management of frequent-fire forest landscapes." The conference is being held in Portland, OR, July 5-10, 2015. Contact: Miguel Villarreal (firstname.lastname@example.org).

USGS scientists to present latest methods for modeling land use and land cover change and potential resource impacts: Human use and alteration of earth’s land surface, combined with global climate changes, pose considerable challenges to biodiversity resilience and resource availability. The USGS has developed spatially explicit models of future land use and land cover (LULC) driven by historical LULC change data to explore plausible land use futures and potential mitigation strategies. Scenarios of future LULC are useful for visualizing alternative futures, examining potential management approaches, and enabling more informed decision-making. We will present our latest modeling results on July 8 at the International Association of Landscape Ecology meeting in Portland, OR. For more information, contact Tamara S. Wilson, Western Geographic Science Center, Menlo Park, CA 94025, USA email@example.com

Conservation planning for climate change resilience: Research co-authored by WGSC CAWSC scientists tests new theory for climate change adaptation and protected area planning. The scientists propose conservation networks designed to capture the full range of climatic diversity in a region will improve the resilience of biotic communities to climate change. In a study of protected areas in the California Bay Area, they test the climate stability of networks using downscaled climate-hydrology projections and new protected area planning methods to assess the overlap between present and future climate conditions. Findings illustrate the heterogeneity of climate stability across the landscape and by planning objective, and suggest new conservation priorities for the region.

State-and-transition simulation modeling of potential land use threats to protected areas in Mediterranean: The Western Geographic Science Center will be presenting new research on the potential effects of projected human land use on California’s existing protected areas and unprotected priority habitat at the Science for Parks, Parks for Science meeting on Thursday, March 26 at U.C. Berkeley. State-and-transition simulation modeling (STSM) was used to simulate spatially-explicit (1 km2) historical and future land-use change from 1992-2060 for the Mediterranean California ecoregion. Spatial model results show the Oak Woodlands with nearly 7,000 km2 of land area within 10 km2 of a protected area boundary threatened by future land use, second only to the California Central Valley with over 2,600 km2. Overall it is estimated that over 18,000 km2 of unprotected yet essential areas for habitat linkages may be threatened by human land use by 2060. Exploring a range of alternative, yet plausible, land-use futures can help guide resource management and mitigation strategies and identify conservation priorities.

New Journal Article Released on Potential Future Impacts to California Rangeland Ecosystem Services: Wildlife habitat, soil carbon, and water supply: Rangeland areas in California’s Central Valley could decline by as much as 37 percent by 2100 due to changes in land use and climate, according to new projections by the U.S. Geological Survey. In a study to better understand the potential impacts of changes in land use and climate on rangeland ecosystems in California, USGS scientists from the Western Geographic Science Center, California Water Science Center and the Science and Decisions Center developed six climate, land use, and hydrological change scenarios for the Central Valley and surrounding foothills. Results show that in addition to habitat loss, increased development of rangelands for urban use increases watershed runoff and, combined with periods of drought, reduces the opportunity for groundwater recharge. The complete research paper, “Integrated climate and land use change scenarios for California rangeland ecosystem services: wildlife habitat, soil carbon, and water supply,” by Kristin Byrd and others was recently released online in the journal Landscape Ecology. A news release is planned for the week of February 23. For more information, contact Kristin Byrd, email@example.com, 650-329-4279.

Understanding model sensitivity for tsunami evacuation potential in Alaska – A new article in Applied Geography by Mathew Schmidtlein at Sacramento State University and USGS geographer Nathan Wood summarizes efforts to examine sensitivity of tsunami evacuation modeling due to land cover assumptions. The coastal community of Seward, Alaska, was used to demonstrate the work. Results suggest that some caution is warranted in interpreting results with higher evacuation times or areas where there is wetland or shoreland because of the inherent model uncertainty. For more information, contact Nathan Wood at firstname.lastname@example.org or 503-251-3291. The article is available online from Applied Geography at http://www.sciencedirect.com/science/article/pii/S0143622814002690.
