Forest harvest is one of the primary landscape-scale management actions affecting riparian forests of the Pacific Northwest, U.S, yet the effect of harvest on headwater steam amphibians is largely understudied. Existing information is often limited because of the difficulty separating movement and emigration processes from occupancy and abundance estimates. We designed a before-after control-impact experiment to account for instream movement in the responses of three unique headwater stream amphibians to clearcut logging as part of the Trask River Watershed Experimental Study in the Oregon Coast Range. We captured and marked larval tailed frogs (Ascaphus truei), Coastal giant salamanders (Dicamptodon tenebrosus),...

This dataset contains information from capture-mark-recapture sampling of Oregon spotted frogs (Rana pretiosa) conducted 2016-2019 by USGS as part of a study relating R. pretiosa survival and abundance to wetland inundation in the upper Deschutes River. Data consist of site, survey, habitat, and species detection covariates, as well as 10 years of hydrological and drought metrics used to establish relationships between river flow and area of inundation at survey sites. Remotely sensed and model predicted area wet estimates for the sites are also given.

Amphibians are among the most sensitive taxa to climate change, and species inhabiting arid and semiarid landscapes at the extremes of their range are especially vulnerable to periods of drought. The Jack Creek, Oregon, USA population of Oregon spotted frogs (Rana pretiosa) faces unique challenges occupying the highest elevation site in the species’ extant range and one that has been hydrologically transformed by loss of American beaver (Castor canadensis). We evaluated the effect of drought mitigation (addition of excavated ponds) on relationships between local water availability, legacy beaver dams, and R. pretiosa population dynamics in the Jack Creek system. We conducted capture-mark-recapture sampling at a...
