Occurrence of Amphibians in Northern California Coastal Dune Drainages

Metadata Updated: October 29, 2023

Many coastal dune ecosystems have been degraded by non-native dune vegetation, but these systems might still provide valuable habitat for some taxa, including amphibians. Because restoration of degraded dune systems is occurring and likely to continue, we examined the occurrence of amphibians in drainages associated with a coastal dune ecosystem degraded by invasive plants (European Beachgrass, Ammophila arenaria, and Iceplant, Carpobrotus edulis). We found that occupancy of three amphibian species (California Red-legged Frog, Rana draytonii; sierran treefrog, Pseudacris sierra; and Rough-skinned Newt, Taricha granulosa) among 21 coastal dune drainages was high, with most coastal dune drainages occupied by all three species. Furthermore, reproduction of Sierran Treefrogs and California Red-legged Frogs was estimated to occur in approximately half and one-third of the drainages, respectively. The probability of occurrence of Rough-skinned Newts and pre-metamorphic life stages of both anurans decreased during the study, perhaps because of ongoing drought in California or precipitation-induced changes in phenology during the final year of the study. Maintaining structural cover and moist features during dune restoration will likely benefit native amphibian populations inhabiting coastal dune ecosystems.
