Meadows delineated in the Sierra Nevada wth refugial status and connectivity rankings–WellConnected (WC), ReallyWellConnected (RC), Stable. Satisfies the delivery of “Sierra Nevada Connectivity Maps” and “Sierra Nevada Meadows Map”. Maps of the Sierra Nevada Meadows designated by their connectivity classification and whether they are expected to have a climate different than historic (1910-1939). We generated maps for modern climate (1970-1999) and four future climate scenarios, broken down into 30 year intervals, in which we assumed connectivity would not change because resistance and conductance surfaces were static. Data for the map are polygon shapefiles of meadows, processed first by buffer and dissolve in...
Freshwater fishes are highly vulnerable to human-caused climate change, resulting in rapid changes in status. Because quantitative data on status and trends are unavailable for most fish species, a rapid assessment approach that incorporates expert knowledge is needed to assess current status and future vulnerability. In this study, we present a method that allows systematic evaluation of potential climate change effects on freshwater fishes, using California as an example. The method uses expert knowledge of the authors, supported by literature reviews of status and biology of the fishes, to score ten metrics for both (1) current status of each species (baseline vulnerability to extinction) and (2) likely future...
Adaptation Planning Workshop #1:We convened a two-day workshop with scientists, managers, conservation practitioners, and others to use the findings of the vulnerability assessment to inform the development of climate-smart adaptation strategies and actions to conserve priority habitats. Specifically, we used the results of the vulnerability assessment to evaluate whether existing management actions may be vulnerable to climate change, and identify opportunities to modify existing actions to reduce vulnerabilities and become more climate-smart. We then focused on identifying climate-smart conservation strategies and actions that are not currently being implemented, but should be considered in order to conserve priority...
Website: “Climate Change Refugia” website features a dynamic, interactive refugia map and all deliverables
This project will conduct a vulnerability assessment, develop climate-smart adaptation strategies and actions, and generate implementation plans for focal habitats of the South and Central Coast regions of the CALCC, with a specific focus on four Southern California National Forests (Angeles, San Bernardino, Cleveland, Los Padres).Specific project goals include:(1) Assess the regional vulnerabilities and resiliencies of focal habitats to climate change and non-climate change stressors.(2) Generate climate-informed maps to identify how vulnerabilities vary spatially to help prioritize conservation areas and activities.(3) Identify implementable climate-smart conservation strategies and actions to conserve priority...
Understanding factors influencing survival of Pacific salmonids (Oncorhynchus spp.) is essential to species conservation, because drivers of mortality can vary over multiple spatial and temporal scales. Although recent studies have evaluated the effects of climate, habitat quality, or resource management (e.g., hatchery operations) on salmonid recruitment and survival, a failure to look at multiple factors simultaneously leaves open questions about the relative importance of different factors. We analyzed the relationship between ten factors and survival (1980–2007) of four populations of salmonids with distinct life histories from two adjacent watersheds (Salmon and Scott rivers) in the Klamath River basin, California....
In this CA LCC-funded Climate-Smart Conservation Planning effort, EcoAdapt’s climate adaptation scientists worked with National Forest conservation managers to conduct vulnerability assessments, develop climate-smart adaptation strategies and actions, and generate implementation plans for key habitats of Southern California, with a specific focus on four National Forests (Angeles, San Bernardino, Cleveland, Los Padres). This effort provides information and example case studies for USFS planning and management (e.g., Forest Plan Revisions, Climate Change Performance Scorecard) among other natural resource management and conservation efforts to prepare for climate change impacts in Southern California.
Vulnerabilities of 27 resources were evaluated during the Vulnerability Assessment Workshop (held March 5-7, 2013); resources included 8 ecosystems (alpine/subalpine, yellow pine/mixed conifer, red fir, wet meadows and fens, oak woodlands, chaparral, sagebrush, and aquatic), 15 species (fisher, marten, bighorn sheep, wood rat, willow flycatcher, mountain quail, sage grouse, Sierra Nevada yellow-legged frog, mountain yellow-legged frog, red fir, blue oak, black oak, whitebark pine, bristlecone pine, and aspen), and 4 ecosystem services (timber and wood products, carbon, fire, and recreation). The vulnerability assessment results are comprised of evaluations and comments from a participant breakout group during the...

Understanding recent biogeographic responses to climate change is fundamental for improving our predictions of likely future responses and guiding conservation planning at both local and global scales. Studies of observed biogeographic responses to 20th century climate change have principally examined effects related to ubiquitous increases in temperature – collectively termed a warming fingerprint. Although the importance of changes in other aspects of climate – particularly precipitation and water availability – is widely acknowledged from a theoretical standpoint and supported by paleontological evidence, we lack a practical understanding of how these changes interact with temperature to drive biogeographic responses....
This vulnerability assessment is an initial science-based effort to identify how and why focal resources (ecosystems, species populations, and ecosystem services) across the Sierra Nevada region are likely to be affected by future climate conditions. This assessment centers on the Sierra Nevada region of California, from foothills to crests, including ten national forests and two national parks. Twenty‐seven focal resources including eight ecosystems, populations of fifteen species, and four ecosystem services were identified as important by the U.S. Forest Service (USFS) as part of their forest plan revision process or by Sierra Nevada stakeholders and are considered in this assessment. Vulnerabilities of these...
This project used species distribution modeling, population genetics, and geospatial analysis of historical vs. modern vertebrate populations to identify climate change refugia and population connectivity across the Sierra Nevada. It is hypothesized that climate change refugia will increase persistence and stability of populations and, as a result, maintain higher genetic diversity. This work helps managers assess the need to include connectivity and refugia in climate change adaptation strategies. Results help Sierra Nevada land managers allocate limited resources, aid future scenario assessment at landscape scales, and develop a performance measure for assessing resilience.

We conducted detailed resurveys of a montane mammal, Urocitellus beldingi, to examine the effects of climate change on persistence along the trailing edge of its range. Of 74 California sites where U. beldingi were historically recorded (1902–1966), 42 per cent were extirpated, with no evidence for colonization of previously unoccupied sites. Increases in both precipitation and temperature predicted site extirpations, potentially owing to snowcover loss. Surprisingly, human land-use change buffered climate change impacts, leading to increased persistence and abundance. Excluding human-modified sites, U. beldingi has shown an upslope range retraction of 255 m. Generalized additive models of past distribution were...
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.
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.
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...
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.
