Phase 1 & 2 (2010, 2012): This project developed a sampling design and monitoring protocol for wintering shorebirds in the Central Valley and in the San Francisco Bay Estuary and develop an LCC-specific online shorebird monitoring portal publicly available at the California Avian Data Center. The three objectives in Phase II of this project are: 1) Complete the shorebird monitoring plan for the CA LCC by developing a sampling design and monitoring protocol for wintering shorebirds in coastal southern California and northern Mexico. 2) Develop models to evaluate the influence of habitat factors from multiple spatial scales on shorebird use of San Francisco Bay and managed wetlands in the Sacramento Valley, as a model...

California’s Central Valley supports over 20 endemic, special-status species associated with vernal pools and seasonal wetlands, yet loss of 90% of the original extent of these habitats has resulted in highly-fragmented, remnant pools of varying habitat quality. Managers need science support to inform conservation priorities and possible enhancement of remaining pools, particularly since projected increases in temperature and decreases in precipitation may dry ponds to an extent that reduces or precludes their habitat value. Ongoing changes in climate will, in turn, cause changes in hydrologic regime, with a decreased hydroperiod expected to detrimentally affect reproductive occupancy of special status species such...
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 main goal of this project is to ensure that the 2011-13 climate change update to the Baylands Ecosystem Habitat Goals Report (Baylands Goals) and other key, ongoing conservation activities in the San Francisco Bay region use the latest information about the current and future status of San Francisco Bay tidal marsh ecosystems, particularly in the context of sea-level rise. The main product of the project is the improved Sea Level Rise (SLR) Tool, specifically upgraded to inform the Baylands Goals Report update. The tool will continue to be available online at www.prbo.org/sfbayslr. All data layers going into the tool are and will continue to be downloadable from the site.
The goal of this project is to create critically needed coastal fog datasets. Anticipated products from the collaboration between on-the-ground natural resource managers and a multidisciplinary coalition of physical scientists are: 1) a compilation of existing fog related data from multiple sources: satellite (AVHRR, GOES, Modis, Landsat), NOAA buoy , and airport and meteorological stations, 2) USGS Open File report documenting the results of a multiday working session with climatologists, remote sensing specialists, fog modelers, statisticians, and natural resource managers, convened to review the data, examine and assess the correlations between data streams and models, specify initial parameters to be extracted...

A century of fire exclusion across many forest types in the western U.S. has resulted in unforeseen changes, including high fuel accumulations, high densities of trees, and increasing dominance of fire-intolerant species. These changes are particularly acute in forests that historically experienced high frequency and low severity fires. In response, the NPS Pacific-West region supports a large prescribed fire program to reduce understory fuels and forest density. Prescribed fire has been generally successful at reducing understory fuels and threats of catastrophic fire, and treated stands are expected to be more resistant to future wildfire. Less well understood is how well prescribed fire confers resistance to...
Conserving migratory or wide-ranging species presents considerable challenges, as these individuals move across disparate jurisdictions often crossing international borders among crucial stages of their annual cycle. Within North America, Migratory Bird Joint Ventures (JVs) have established successful partnerships to coordinate the planning and delivery of conservation actions within key regions to benefit migratory bird populations. However, the extent to which local conservation actions influence regional demographics and in turn affect continental population dynamics remains poorly understood. Maximizing efficient use of limited resources to conserve habitats for wide-ranging species has motivated a critical...
The CA Academy of Science and Point Blue Conservation Science conducted a systematic analysis of uncertainty in modeling the future distributions of ~50 California endemic plant species and ~50 California land birds, explicitly partitioning among 5 alternative sources of variation and testing for their respective contributions to overall variation among modeled outcomes. They mapped the uncertainty from identified sources, which can guide decisions about monitoring, restoration, acquisition, infrastructure, etc., in relation to climate change.

The Mediterranean climate region of southern and coastal California is a globallyrecognized biodiversity hotspot, in addition its natural landscapes provide a suite of ecosystemservices including water provision to the high density urban populations and agricultural lands inclose proximity. The provisioning of water is also critical to sustained ecological function,including habitat for endangered species like the southern California steelhead. Given theimportance of water provisioning and other ecosystem services, there is surprisingly little knownregarding their vulnerability to future climates and increasing fire in southern California.This is particularly concerning given the predicted impacts of climate change...
Project Goal The goal of this project is two-fold: 1) to increase the understanding of how meadow restoration impacts hydrology and 2) to inform management and investment decisions around using restoration as a tool to build resilience under climate change. Objectives in support of this goal include: - Complete data collection and analysis and publish peer-reviewed research article on the results of groundwater and surface water measurements before and after restoration in Indian Valley Meadow (Eldorado National Forest) - Double the published scientific literature on the water supply benefits of meadow restoration and produce the first empirical study - Estimate groundwater and base flow (late season groundwater...
This project researched the expected variation in avian demographic responses to environmental change across a gradient of species and landscapes from the San Francisco Bay to the Central Valley of California. We used two avian taxa, waterfowl and songbirds, as case studies for the integration of long-term demographic data with climate change variables. For each taxon, we assessed and synthesized several demographic responses to climate change variables (i.e., precipitation and temperature) to explore the relationship between four large-scale climate indices and bird species arrival dates and nest survival. A web-based application provides natural resource managers with project results.
This project brought together natural resource managers, conservation coordinators and planners, and scientists working at multiple scales within the San Francisco Bay to develop a spatially-explicit decision framework that cuts across jurisdictional boundaries while accounting for uncertainties about climate change. In particular, the SDM framework allows managers within the Bay to identify a recommended strategy among a set of alternative strategies that may vary among its subregions (e.g. North Bay, South Bay, East Bay). Management priorities will be those that yield the greatest expected conservation benefits across the Bay considering multiple objectives including endangered species recovery (e.g. California...
This project is analyzing downscaled climate model data to assess the geography of climate change at scales relevant to actual conservation actions. This work analyzes the California Essential Habitat Connectivity products to determine which protected lands are most vulnerable and which of the proposed corridors would partially mitigate climate change threats.
