This database contains literature citations and associated summaries pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on the Oregon spotted frog (Rana pretiosa) and other listed/sensitive wetland-breeding amphibians in the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance. *HINT: If you are looking for the database SEARCH TOOL, scroll down to 'Attached Files' and download 'Annotated_bibliography_with_search_tool.accdb.'

We used visual surveys to document the presence of all life stages of Cascades frog (Rana cascadae) at historically occupied sites. We surveyed 67 sites 1-2 times between May and August of 2018 and 2019. This effort was a continuation of 2001-2004 surveys conducted at the same site pool. This dataset includes counts of amphibians, reptiles, and fish observed during each site survey, as well as habitat covariates.

This dataset contains information from mark-recapture and egg mass surveys conducted 2015-2018 by USGS as part of an ongoing Oregon spotted frog (Rana pretiosa) monitoring effort at Jack Creek, Klamath County, Oregon. Data consist of spotted frog counts (handled by surveyors) aggregated by date, location, life stage, and sex, as well as data on environmental conditions at the time each survey. Note that due to updates in access permissions, surveyed area within each site varies over time. Thus, counts are not comparable among year, as surveyed area was not held constant.

The data included here were gathered to determine the effects of cattle grazing on wetland water quality in the Klamath National Wildlife Refuge in Oregon. Surface water samples from sites representing a range of grazing histories were collected between June and October in 2017 and 2018. Samples were analyzed for nutrients (ammonia, nitrate plus nitrite, nitrite, and orthophosphate), total coliforms, E. coli, enterococci, and estrogenicity by U.S. Geological Survey laboratories. Basic water quality parameters such as temperature, pH, turbidity and specific conductance were also collected in the field during each site visit. Quality assurance samples (blanks and replicates) as well as method information is also included...
