Principal components of climate variation in the Desert Southwest for the time periods 1980-2010, 2040-2070 (RCP8.5) and (RCP4.5)

Five principal components are used to represent the climate variation in an original set of 12 climate variables reflecting precipitation and temperature gradients. The dataset provides coverage for four regions (the Sonoran Desert, Mojave Desert, Colorado Plateau, and Southern Great Basin) and two time periods: current climate (defined as the 1980-2010 normal period) and future climate (defined a

Site table and bias corrections for Coastal Data Information Program (CDIP) hind casts at the California Channel Islands

We present correction coefficients for hourly wave height and period hind casts for 32 sites throughout the Channel Islands National Park and San Nicolas Island. Each site is described in terms of its location, orientation, and transect depth. To use this table, first generate a site-specific wave height and period hind cast using the California Coastal Data Information Program (CDIP) Monitoring

Hourly wave-height observations from 2013 to 2017 at 32 sites throughout the Channel Islands National Park and San Nicolas Island

Hourly wave-height observations at 32 sites throughout the Channel Islands National Park and San Nicolas Island, site-specific hind casts from the Coastal Data Information Program (CDIP), and contemporary wave height, period, and direction from regional buoys taken during intervals between 2013 and 2017.

Hourly wave height and period hindcasts at 32 sites throughout the Channel Islands National Park and San Nicolas Island from 2000-2017

California's Coastal Data Information Program (CDIP) has a hind cast feature that allows one to model hourly height and period at known locations back to 2000. Fitting these hindcasts to observed height and periods indicates that the hindcasts have consistent biases that can be corrected for statistically. Past work generated bias corrections for 32 sites in the Channel Islands. We use these bias

Distribution and Population Genetic Structure of Coastal Cactus Wrens in Southern California

Data presented are 1.) the locations where Coastal Cactus Wren (Campylorhynchus brunneicapillus) genetic samples were collected in southern California, in 2011, 2012, and 2013; 2.) 2012 and 2013 survey results; 3.) the territory locations of all Cactus Wrens detected in 2011, 2012, and 2013 in Orange, Riverside, and San Diego counties; and 4.) dispersal results on a subset of Cactus Wrens color ba

Genetic Structure of California Gnatcatcher Populations in Southern California from 2012 through 2013

These data were collected to determine how genetic variation is arrayed across remaining populations of gnatcatchers, allowing inference about individual movement and gene flow patterns among those populations. The work focused on determining the extent to which gnatcatcher aggregations function as an interconnected metapopulation, with aggregations exchanging migrants across a fragmented landscap

Genotypes for six rare plant species found in San Diego County in 2016-2017

To understand the genetic structure of six rare plant species (Acanthomintha ilicifolia, Baccharis vanessae, Chloropyron maritimum ssp. maritimus, Deinandra conjugens, Dicranostegia orcuttiana, Monardella viminea), we obtained samples from known occurrences in San Diego County, prepared and sequenced ddRAD genomic libraries, and developed and analyzed a panel of genetic markers to assess populatio

Chaparral Type Conversion into Herbaceous Vegetation in Coastal Southern California from 1947 to 2014, Data Compiled from Aerial Imagery, Geographic NAD83 (2017)

This dataset contains data pertaining to vegetation type, woody versus herbaceous versus non-vegetated, for a random selection of points within the Santa Monica Mountains National Recreation Area of Southern California. These data were obtained from aerial imagery for the years 1947, 1977, 1995, 2005, and 2014 and were used to determine changes in cover type over time. These data support the

Annual California Sea Otter Census-2018 Spring Census Summary

The spring 2018 mainland sea otter count began on April 26, and was completed by May 24, 2018. Overall viewing conditions this year were good and rounded off to the same conditions experienced during the 2017 spring census (View Score 2.4, where 0=poor, 1=fair, 2=good, 3=very good, and 4=excellent). The surface canopies of kelp (Macrocystis sp.) were considered by most participants to be above nor

Summary of Stranded Southern Sea Otters, 1985-2018 (ver. 3.0, June 2021)

The southern sea otter (Enhydra lutris nereis), also known as California sea otter, was listed as threatened in 1977 under the Endangered Species Act. Since 1985, stranded otters from throughout their California coastal range have been collected and analyzed to inform resource management on recovery and conservation of the species. This data set is a complete 31 year compilation. Future annual str

Spatial predictions of habitat suitability for present-day (1950 - 2000 yr) and mid-Holocene (8.3 ka - 4.2 ka) time intervals

This dataset provides spatial predictions of habitat suitability for current (1950 - 2000 yr) and mid-Holocene (8.3 ka - 4.2 ka) intervals using hindcasting, and three separate paleo-distributions calibrated on the packrat midden archive: those without bias correction (naive), those created with a standard method (standard), and those created with a novel alternative (modeled) incorporating a thre

Masticophis occupancy in southern California, 1995-2000

These data are CSV files comprised of a heading and tables from Appendix 1 and Appendix 2 in the accompanying paper. The tables show the sampling dates and locations for the coachwhip (Masticophis flagellum) and striped racer (Masticophis lateralis) in pit-fall arrays (Fisher et al. 2008) monitored in southern California from 1995-2000. GPS data are shown in decimal degrees and were collected in t
