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.
This site is part of ongoing studies of Oregon spotted frog habitat use and population dynamics throughout its Pacific Northwest range. The results of this study will contribute to our understanding of the biology of this sensitive species and can have implications for improved management efforts.

expert advice;;identification keys
After being trained on proper species identification in the field, crew members used a variety of resources to ensure species identifications were robust. If an animal could not be positively identified during a survey, it was captured with a dip-net and examined closely. If any uncertainty remained, the observer referred to a field guide and/or took photos of the animal to be reviewed by an expert. Oregon spotted frogs are easily distinguishable from most other amphibian species in our study area. Thus, we are confident in the accuracy of our identifications.

Field data were collected on paper and reviewed (QA/QC) in the field for accuracy and completeness by one member of the crew (not the data recorder) at the end of each survey. Those data were entered into a Microsoft Access database and reviewed by a different individual to confirm that the data had been entered correctly. Once all data were entered and checked for completeness and accuracy, a random 10 percent subsample of that year’s surveys were once again screened for errors.
Data were checked for logical consistency by writing grouping queries to examine the proper spelling and standardization of all text fields. Range queries were written to confirm that numerical values were not outside a reasonable range for a particular field. We performed outlier checks by plotting numerical values bounded within a range (e.g., elevation, temperature, frog snout-urostyle length (SUL), frog mass). Bounding dates were confirmed as correct. Site coordinates were reviewed with Maptech, ArcMap, or other mapping software.
Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
GPS data were downloaded from the device at the end of the field week. Spatial data were projected on an ArcMap layer to ensure positional accuracy.
No formal positional accuracy tests were conducted.
Data from datasheets were entered into respective project databases.

Field
Oregon spotted frog breeding surveys were conducted at Davis Flat, Middle Jack, and Upper Jameson on March 26, April 8, and April 9 of 2015, April 26-27 and May 3-4 of 2016, May 3-10 of 2017, and April 19 - May 9 of 2018. We also surveyed Lower Jameson on April 25 and Moffitt on May 9 of 2018. During each site visit, surveyors counted Oregon spotted frog egg masses (keeping track of old and new masses) and quantified oviposition site variables. Mark-recapture surveys were completed Sept 1-3 in 2015; July 26-28 (Upper Jameson) and Aug 1-3 (Middle Jack) in 2016; Aug 29-31 (Middle Jack and Upper Jameson), Sept 5-6 (Davis Flat and Yellow Jacket), and Sept 28-29 (8821 Road and Lower Jameson) in 2017; and June 25-27 (Lower Jameson), July 17-19 (Middle Jack and Upper Jameson), and July 30-Aug 1 (Davis Flat and Yellow Jacket) in 2018. At each pond/site, crew members worked in pairs or individually to search for Oregon spotted frogs in all suitable microhabitats. Upon entering a site, researchers sanitized hands with 70 percent alcohol-based sanitizer and allowed it to dry before rinsing hands in site water. Hands were sanitized between the handling of individual frogs. During each site visit, sub-adult and adult frogs (> 40 mm SUL) were caught, scanned for a PIT tag, given a new tag if necessary, and released at the point of capture. Every effort was made to complete the process efficiently with minimal disturbance to the frog. A sterilized PIT tag was inserted into the dorsum of a suitably-sized frog only after researchers confirmed (by scanning with a tag reader and visual inspection) that the frog did not have an existing tag. Once inserted, the PIT tag was manipulated into proper position under the skin just above the urostyle. If it was necessary to hold animals in queue for processing, each individual was placed in a separate zip-closure plastic bag filled with site water and vegetation. Animals were held in shaded areas and for no longer than 15 minutes. When a frog was captured, it was processed efficiently and released as to reduce disturbance to the frog.
