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...
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...
Tidal marsh habitat is at high risk of severe loss and degradation as a result of human uses, sea-level rise, changes in salinity, and more frequent and extreme storms projected by climate models. Availability of habitat is a prerequisite for long-term viability of marsh bird populations and this has been modeled in a companion California Landscape Conservation Cooperative project (Veloz et al. 2011). However, habitat alone will ensure neither resilience nor recovery of depleted and threatened populations. To provide management guidance to reduce species’ vulnerability and recover depleted populations, we developed interactive population dynamic models for four key marsh species: Black Rail, Clapper Rail, Common...
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...
Website: “Climate Change Refugia” website features a dynamic, interactive refugia map and all deliverables
This project designed a monitoring program and protocol to detect the effects of climate change on tidal marsh bird population abundance and distribution. It is a companion to “Tidal Marsh Bird Population and Habitat Assessment for San Francisco Bay under Future Climate Change Conditions” and will build on its products, enabling evaluation of the long-term viability of four tidal-marsh bird species threatened by impacts of climate change: Clapper Rail, Black Rail, Common Yellowthroat, and Song Sparrow (three endemic subspecies: San Pablo, Suisun, and Alameda). Information is available through the California Avian Data Center. See also: http://data.prbo.org/apps/sfbslr/index.php?page=lcc-page
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....
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....
Environmental Change Network: Current and Future Zonation PrioritizationZonation is a spatial conservation planning software tool that can take into account multiple species to create a hierarchical prioritization of the landscape. This is in contrast to other spatial conservation planning tools which may require predefined conservation targets or areas. Here, we used 199 California landbirds along with Zonation’s “core-area” algorithm to prioritize the California landscape. Species were weighted according to the California Bird Species of Special Concern criteria and probability of occurrence was discounted by distribution model and climate model uncertainty surfaces.The dataset provides priority areas for “current”...
Purpose:The purpose of this Walker Basin Meadows Condition Report is twofold. First, it provides condition data and explains why the Walker Working Group chose the first set of meadows as the top priority for restoration. Second, the working group will use information presented here to plan subsequent restoration efforts once the first group of meadows is restored.Introduction:Meadows of the Walker River basin are an extremely valuable component of the landscape. Meadows provide diverse habitat, including habitat critical to endangered species. They reduce peak flows during storms and soak up spring runoff, recharging groundwater supplies. Meadows filter sediment, provide forage, and are important cultural and recreational...

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.

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.

The vulnerability of species at risk from climate change is recognized as an important issue in California as well as globally. Assessing vulnerability requires information on the long-term viability of populations and understanding the influences on that viability, due to environmental drivers as well as impacts of management action. We developed population-dynamic models to assess and better understand the long-term population viability of four key, tidal marsh-dependent species, under a variety of environmental conditions, including climate change impacts. In the San Francisco Estuary, each species is represented by one or more subspecies that is entirely or mainly confined to the tidal marsh habitat in the region:...
An online decision support tool for managers, planners, conservation practitioners and scientists.The models generating these maps are the first to take into account the ability of marshes to accrete, or keep up with, rising sea levels, in the San Francisco Bay Estuary.PRBO has generated a series of scenarios to provide a range of projections to address the uncertainty in future rates of sea-level rise and suspended sediment availability.Our maps cover the entire Estuary allowing for analyses at multiple spatial scales.This tool displays maps created at a high spatial resolution using the best available elevation data. The website will be continually updated as new data becomes availableThe tool is the first to...
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...
