These maps display the magnitude of projected future climate change in relation to the interannual variability in late 20th century CA climate. The maps show the standardized Euclidean distance between the late 20th century climate at each pixel and the future climate at each pixel. The standardization puts all of the climate variables included on the same scale and down weights changes in future climate which have had large year to year variation historically. Warmer colors indicate greater climate change and cooler colors indicate less extreme climate change.
Bird community turnover for current and future climate (GFDL) based on maxent models for 198 land bird species.
Understanding the environmental contributors to population structure is of paramount importance for conservation in urbanized environments. We used spatially explicit models to determine genetic population structure under current and future environmental conditions across a highly fragmented, human-dominated environment in Southern California to assess the effects of natural ecological variation and urbanization. We focused on 7 common species with diverse habitat requirements, home-range sizes, and dispersal abilities. We quantified the relative roles of potential barriers, including natural environmental characteristics and an anthropogenic barrier created by a major highway, in shaping genetic variation. The...
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.
Workshop on Climate Smart Land Management (with focus on invasive plants) at Cal-IPC Symposium, October 2013.
Maps showing projected future range of 79 invasive plants, based on current (2010) and future (2050) climate. Models used an ensemble of 17 Global Circulation Models from PRISM and were run using (open source) Maxent software. Maps are posted on CalWeedMapper (https://calweedmapper.cal-ipc.org/maps/).
We utilized recommendations from the Baylands Ecosystem Habitat Goals Update process to identify optimal allocations of limited funds across space and time for conservation in the SF Bay. Subregional-scale alternative allocations of resources were evaluated for maximizing conservation benefits at a Bay-wide scale. The allocations will address uncertain climate change impacts along with budgetary and regulatory constraints. To identify optimal allocations we conducted an expert-facilitated Structured-Decision-Making (SDM) process consisting of : Four 2-hr webinars in April 2014 [Completed] One 2.5-day workshop in May 2014 The final outcome was a set of subregional resource allocations that are based on decision-analytic...
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,...
Average percent change in multiple ecosystem services from 2010 to 2040 These maps display the average percent change in three rangeland ecosystem services – total ecosystem carbon, critical habitat and water availability – from 2010 to 2040 for three IPCC-SRES scenarios (A1B, A2 and B1) and two climate projections (warm, wet future and hot, dry future). Total ecosystem carbon is total carbon stored in vegetation and soils (up to 20 cm in depth), and was estimated annually from 2006 to 2050 by the U.S. Geological Survey’s General Ensemble Biogeochemical Modeling System (GEMS) (http://www.usgs.gov/climate_landuse/land_carbon/BGM.asp). See Percent change in total ecosystem carbon dataset page for model details. Critical...
Significant efforts are underway to translate improved understanding of how climate change is altering ecosystems into practical actions for sustaining ecosystem functions and benefits. We explore this transition in California, where adaptation and mitigation are advancing relatively rapidly, through four case studies that span large spatial domains and encompass diverse ecological systems, institutions, ownerships, and policies. The case studies demonstrate the context specificity of societal efforts to adapt ecosystems to climate change and involve applications of diverse scientific tools (e.g., scenario analyses, downscaled climate projections, ecological and connectivity models) tailored to specific planning...
Final Report to the California Landscape Conservation Cooperative (funding agency for CADS Phase 1), and interim report to the US Fish & Wildlife Service National Wildlife Refuge System Inventory and Monitoring Initiative.This report provides recommended resource allocations for conserving four subregions of San Francisco (SF) Bay, including North Bay, Suisun, Central Bay and South Bay. These recommendations are based on quantitative, subregional decision tools that were developed in collaboration with stakeholders working in each subregion. The authors of this report would like to thank all the participants, including the leadership team and other stakeholders that included natural resource managers and planners...
Strategic plans list eradication and surveillance species for a multi-county region, as agreed upon by local land managers. Most species are based on the Cal-IPC Inventory and maps in CalWeedMapper. The purpose of these plans is to enable land managers to apply for grants for coordinated projects in their region. The emphasis is on species that can be eradicated within five years and species that are just outside the region and have a high probability of invading. The plans are available on the CalWeedMapper website at https://calweedmapper.cal-ipc.org/regions/.
When: May 29, 2014 1:00 - 3:30 PMWhere: Department of Water Resources, Large Conference Room, 2nd Floor, Bonderson Building, 901 P Street, Sacramento, CA 95814The project evaluates the effects of different climate change and land use change scenarios on ecosystem services (water availability, wildlife habitat and carbon sequestration) provided by rangelands in California. The project is a partnership between the USGS and Defenders of Wildlife and it is funded by the California Landscape Conservation Cooperative.More information, an online tool and associated data are available at http://climate.calcommons.org/aux/rangeland/index.html.A fact sheet with information about the project can be found at http://pubs.usgs.gov/fs/2014/3019/.
This project analyzed 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.
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...

The North-central California coast and ocean is a globally significant and extraordinarily productive marine and coastal ecosystem that boasts an array of local, state and federal protected areas and other managed lands. Despite this richness and attention to conservation, this region is still vulnerable to the effects of climate change. The Greater Farallones National Marine Sanctuary Advisory Council (Council) convened the multi-agency Climate-Smart Adaptation Working Group (Working Group) in response to the need to develop climate-smart adaptation strategies to enable coastal and marine resource managers to respond to, plan, and manage for the impacts of climate change. Working Group members sought to provide...
The Basin Characterization Model (BCM) dataset provides historical and projected climate and hydrology data at a 270 meter resolution, which is relevant for watershed-scale evaluation and planning.
