PI collected water quality samples from amphibian breeding sites at Gourley Pond, Finley Cane Sinks, the Sinks, and Gum Swamp to assist an amphibian monitoring initiative (GRSM-00105). The geological and cultural features and histories associated with each site are also described. April samples show that the waters have low pH (3.9-6.2), low specific conductance, and variable dissolved oxygen concentrations. Aluminum and iron levels were somewhat elevated, except at Gourley Pond, which gets much of its water from stream overflow. Only traces of mercury were present in the water samples. August samples were taken from the only two ponds with water at that time (Finley Cane #2 and the Sinks) but the results of their analysis is missing from the annual report.

This data set contains information on detections of anuran (i.e., frogs and toads) species at six different management areas in the midwestern United States from 2002 to 2012. From 2002 to 2005 anuran communities were surveyed during the day using multiple methods at individual study wetlands—visual encounter surveys, dip net surveys, and calling surveys using multiple observers in most cases. Data are presented from each survey. From 2008 to 2012 amphibian communities were surveyed through detections of vocalizing anurans recorded by automated recording units. Automated recording units recorded five minutes at the top of every hour for the entire field season (typically April through October). Recorder data are presented for up to 15 confirmed detection dates per site per species. Original raw acoustic recordings used to create this data table are archived at the Upper Midwest Environmental Science Center.

This dataset contains information from surveys conducted 2004-2015 by USGS as part of a long-term amphibian monitoring effort in the Willamette Valley, Oregon. Data consist of site, survey, habitat, and species detection covariates.
