These data describe the maximum water depth in each studied coastal dune drainage in each study year. Water depth is used as a proxy for hydroperiod, and is a good indicator of the relative persistence of surface water among sites that can be collected in a single visit.

These data indicate whether a premetamorphic or any life stage of each amphibian species (sierran treefrog Pseudacris sierra, California red-legged frog Rana draytonii, and rough-skinned newt Taricha granulosa) was detected in a survey. These data, combined with the survey data, are necessary for modeling occupancy while accounting for imperfect detection. Surveys for which no detections occurred do not appear in this file, but are in the survey data file (Survey_Data_for_Occupancy_of_Amphibians_in_Northern_California_Coastal_Dune_Drainages_2014_2016).

These data provide information on the relationship between California red-legged frogs and their habitat in a unique ecosystem to better conserve this threatened species while restoring habitat for rare dune plants and animals.

These data describe the date, time (night vs. day), observer, and air temperature of each amphibian occupancy survey conducted in coastal dune drainages from 2014 through 2016. Survey-specific covariates explain patterns in detection probabilities among surveys, thereby reducing bias in occupancy models and improving future surveys.

California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, including coastal dunes, remains obscure. To avoid and minimize potential negative effects of dune restoration activities, we studied the spatial ecology, habitat selection, and survival of California Red-legged Frogs in coastal dune drainages at Point Reyes National Seashore, California. Frogs remained in their home drainages throughout the summer, and, with some notable exceptions, most remained close to water. Home ranges of California Red-legged Frogs in dunes were generally small, and they selected areas near water with logs that served...
These data are multi-state capture histories of 273 individual San Francisco gartersnakes collected at a site before and after a portion of the site was burned. Data collection began in 2008 and continued until 2013, and the prescribed fire was applied in the fall of 2010. These data support the following paper: Halstead, B. J., Thompson, M. E., Amarello, M. , Smith, J. J., Wylie, G. D., Routman, E. J. and Casazza, M. L. (2018), Effects of prescribed fire on San Francisco gartersnake survival and movement. Jour. Wild.
