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...

This dataset contains monthly average hours of fog and low cloud cover (FLCC) per day for North and Central Coastal California. The set of 42 grids has one for each summer month (June, July, August, and September) for each year (1999 - 2009), except for 2 missing months (June 2001 and August 2006) . Grid cell values were calculated using eleven years of hourly, day and night, cloud maps derived from geostationary operational environmental satellite (GOES) images collected and processed by the Cooperative Institute for Research in the Atmosphere (CIRA).For more information about this data and the Pacific Coastal Fog Project, see http://geography.wr.usgs.gov/fog (link is external) (link is external) and this article...

A combination of citizen science inventories and expert assessments will be used to collect critical baseline information on known spring and seep resources using the Spring Ecosystem Inventory and Assessment Protocols and adapting them as needed for the unique arid Sky Island ecosystems. The assessment will collect information on channel morphology, riparian and wetland vegetation, water quality, aquatic macroinvertebrates, and wildlife. This information will be combined with historic data from cooperating agencies (Pima County, Santa Cruz County, USFS, NPA, USGS, USFWS, BLM, and AGFD) in a regional, on-line database to provide a landscape level context for managing resources, which was previously unavailable due...

Texas Tech University will conduct quantitative and predictive analysis of the connectivity of isolated desert “wetlands”, that include tinajas, the name for eroded pools in bedrock, for 20 wildlife species over the Sonoran desert ecoregion. Potential loss of wetlands due to climate change will also be studied to identify high value areas that can be prioritized for future restoration efforts and targeted for better management practices.Target species for landscape connectivity analysis include:Colorado River toad ( Incilius alverius )American bullfrog ( Lithobates catesbeianus )Chiricahua leopard frog ( Lithobates chiricahuensis )Lowland leopard frog ( Lithobates yavapaiensis )Couch’s spadefoot ( Scaphiopus couchii...
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....

BayGEO Journal Article by Alicia Torregrosa explaining the challenges of mapping fog and the techniques used to create the Fog and Low Cloud Cover map generated from GOES imagery. Karl the Fog is a twitter handle @KarlTheFog for fog watchers.Intro:Within the world of mapping, clouds are a pesky interference to be removed from satellite remote sensed imagery. However, to many of us, that is a waste of pixels. Cloud maps are becoming increasingly valuable in the quest to understand land cover change and surface processes. In coastal California, the dynamic summertime interactions between air masses, the ocean, and topography result in blankets of fog and low clouds flowing into low lying areas of the San Francisco...
Each of full climate models (excluding vegetation and elevation variables for which there were no future projections) were subsequently projected onto predicted future climate layers from the IPCC 4th Assessment Report A1B climate change scenario for the decades 2050-2060 and 2080-2090. These predictions represent conservative efforts, however, as the predictions of atmospheric CO2 concentrations may be reached much sooner, as current emissions already exceed the trajectories of the highest scenarios. Thus, projections of genetic variation on the 2080-2090 climate scenarios are likely relevant for purposes of our study. From the predictions of genetic variation under current and future climate, we generated a change...
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...
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...
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.
A survey of natural resource specialists and land managers was conducted at the beginning of the Pacific Coastal Fog Project. Survey results showed that the most urgently needed dataset was a fog frequency map to help make better natural resource decisions for ecosystem restoration, conservation, and preparing for future climate conditions. Fog maps like these could show which areas receive more or less (or no) fog. This data would help land managers understand the influence of fog on patterns of vegetation distribution, wildfire severity, and stream temperature.The U.S. National Weather Service (NWS) has used satellite camera imagery feeds since 1960 to improve real-time weather forecasting. Originally the images...
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...

Sky Island Alliance will develop science and conservation-based guidance to assist natural resource managers in responding to expected climate change and other stressors on springs ecosystems in sky island regions of the Desert LCC. The project will result in publication of an Arizona Springs Restoration Handbook, which will aid managers in directing limited resources to preserve these key water resources and species that depend on them.
To climate scientists, marine fog’s physical opacity symbolizes how much remains to be discovered about the atmospheric phenomenon. This article outlines what is known and unknown about fog and its relationship with climate change.
The raster grids in this dataset show the relative amount of summertime fog and low cloud cover (FLCC) over a decade for North and Central Coastal California on either a monthly or annual basis. Summertime FLCC is calculated as the average FLCC hours per day from an archive of hourly, day and night, June, July, August, and September, 1999 - 2009, GOES (geostationary operational environmental satellite) images collected and processed into ~26, 000 cloud maps by the Cooperative Institute for Research in the Atmosphere (CIRA). These decadal average FLCC rasters do not include years 2001 and 2006 due to missing or incomplete data for June 2001 and August 2006.Layers included:Files, Description1 Decadal Summer (average...
