Sites were chosen from Yosemite National Park maps. Larger meadows were prioritized and although most the meadows were within a day’s hike from a trailhead, several were tens of kilometers from the nearest road. Previous research (Morelli et al 2012 Proceedings of the Royal Society B) showed that detectability was very high (>95% with only one visit) so most sites were visited only one or two times although always with two experienced observers. Sites were surveyed on foot for at least 30 minutes during morning or evening hours. A site would be considered occupied if only one Belding’s ground squirrel was detected but in reality numerous individuals were detected at all occupied sites.
Webinars for regional stakeholders to present findings of the Vulnerability Analysis and Adaptation Planning and encourage participation in subsequent workshops.
In a rapidly changing climate, effective bird conservation requires not only reliable information about the current vulnerability of species of conservation concern, but also credible projections of their future vulnerability. Such projections may enable managers to preempt or reduce emerging climate-related threats through appropriate habitat management. We used NatureServe’s Climate Change Vulnerability Index (CCVI) to predict vulnerability to climate change of 168 bird species that breed in the Sierra Nevada mountains of California, USA. The CCVI assesses species-specific exposure and sensitivity to climate change within a defined geographic area, through the integration of (a) species’ range maps, (b) information...
Maps have been generated to detail the current and historical biodiversity (no. of species per HUC 12) and imperilment (no. of species existing/no. of species historically * 100 per HUC12) for the entire state. Data is being combined with data for invertebrates and a larger set of maps will be published in 2015-16.

The USDA Forest Service (USFS) builds two versions of percent tree canopy cover (TCC) data to serve needs of multiple user communities. These datasets encompass the conterminous United States (CONUS), Coastal Alaska, Hawaii, and Puerto Rico and U.S. Virgin Islands (PRUSVI). The two versions of data within the v2021-4 TCC product suite include: - The raw model outputs referred to as the annual Science data; and - A modified version built for the National Land Cover Database referred to as NLCD data. They are available at the following locations: Science: https://data.fs.usda.gov/geodata/rastergateway/treecanopycover/ https://apps.fs.usda.gov/fsgisx01/rest/services/RDW_LandscapeAndWildlife NLCD: https://www.mrlc.gov/data...
This dataset includes Climatic Water Deficit (CWD) change, average winter (Dec, Jan, Feb) and average spring (Mar, Apr, May) snowpack change, recharge change, and runoff change from Basin Characterization Model (BCM) output using the GFDL and PCM A2 Scenarios in Sierra Nevada California, for 2010-2039, 2040-2069 and 2070-2099. The data was processed using historic (1979-2000) and future (2010-2039; 2040-2069; 2070-2099) values to calculate change. CWD: The term climatic water deficit defined by Stephenson (1998) is quantified as the amount of water by which potential evapotranspiration (PET) exceeds actual evapotranspiration (AET). This term effectively integrates the combined effects of solar radiation, evapotranspiration,...
The CA LCC-funded project “A Climate Change Adaptation Strategy for Sierra Nevada Birds “ applied the NatureServe Climate Change Vulnerability Index tool to assess vulnerability of 168 bird species that breed in the Sierra Nevada and developed a peer-reviewed Climate Change Adaptation Strategy for Sierra Nevada bird species that are most vulnerable to climate change. “Sierra Nevada Bird Vulnerability Assessment Matrix” provides the individual vulnerability factor scores upon which the vulnerability rankings are based.
Are there places that buffer species from climate change? If so, where are they, and can species get there? California natural resource managers need to develop climate change adaptation strategies to address the responses of species to warming trends, shifting precipitation regimes, and changes in vegetation communities. Climate change refugia – areas that remain relatively stable as the climate changes – are important to consider in adaptation planning, but little was known about the nature and distribution of these places.In the CA LCC-funded project “Determining Landscape Connectivity and Climate Change Refugia Across the Sierra Nevada”, researchers mapped the meadows of the Sierra Nevada and used data on the...

This project brings together the major partners involved in road-stream crossings to assess river and stream continuity and set priorities for restoring connectivity, and reducing flood damage to road crossings, within the North Atlantic region.

This project used the NatureServe Climate Change Vulnerability Index tool to assess vulnerability of 140 bird species that breed in the Sierra Nevada and will develop a peer-reviewed Climate Change Adaptation Strategy for Sierra Nevada bird species that are most vulnerable to climate change. The Strategy provides recommendations for actions that managers can take now and in the future to bolster resilience to climate change.

Hydrologic reconnaissance of Mineral Creek near Silverton, Colo., was conducted from June 25-27, 2020. Both banks of Mineral Creek and the adjacent hillsides were walked, starting near the ghost town of Chattanooga and proceeding downstream to the confluence of Mineral Creek with the Middle Fork of Mineral Creek. The purpose of this reconnaissance was to identify areas of emergent groundwater on the right (EGR) and left (EGL) banks, a task that was accomplished by following observed surface flows (seeps and springs) upgradient to the point at which they emanated from the subsurface. Coordinates, using a handheld global positioning system (GPS) device, and photographs were obtained at these locations of emergent...
This cooperative effort by USDA Forest Service Research and the National Forest System assesses the state of knowledge related to the conservation status of four forest carnivores in the western United States: American marten, fisher, lynx, and wolverine. The conservation assessment reviews the biology and ecology of these species. It also discusses management considerations stemming from what is known and identifies information needed. Overall, we found huge knowledge gaps that make it difficult to evaluate the species' conservation status. In the western United States, the forest carnivores in this assessment are limited to boreal forest ecosystems. These forests are characterized by extensive landscapes with...

Sky Island Alliance (SIA) is a non-governmental organizational that works to protect and restore the rich natural heritage of native species and habitats in the Sky Island Region. We work with volunteers, scientists, land-owners, public officials, and government agencies to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity. Because of our long-standing collaborative relationships with land managers and our large corps of skilled volunteers, we were in a unique position to spearhead this project.SIA initiated this springs inventory, assessment and management planning project to develop baseline information on springs in the Sky Island...

This project will produce an existing vegetation type map at 30m resolution for the entire Western Alaska LCC region. The lack of a consistently mapped vegetation data layer for Alaska has been identified as a primary road block for many conservation and management entities across the state. This project will address a number of the LCC conservation goals by addressing a baseline science need that is the foundation for current and future project within the region.

Overview This project examines the ecological impacts of several introduced and expanding forest insects and diseases on forest habitats across the northeastern US and upper Lake States region. To address these novel threats, this work applies large-scale, co-developed experimental studies documenting impacts of ash mortality from emerald ash borer on lowland black ash communities in the Lake States and northern hardwood forests in New England; regional assessments of the impacts of the climate change-mediated expansion of southern pine beetle into northeastern pine barren communities; and ecological characterizations of areas experiencing suppression efforts to reduce the spread of the introduced Asian long-horned...
