Survey Data of Amphibians in Northern California Coastal Dune Drainages (2014 - 2016)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-30T00:00:00Z
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.
