The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Ecology: Found in streams, lakes, ponds, and wet prairies. Often called the "meadow frog" due to its wandering well away from water in the summer time. Individuals may congregate under submerged logs or rocks during the winter.  Lays eggs from March to May; tadpoles transform in late June to August.

Remarks: Frost et al. (2006) revised the genus Rana and most of the North, Central and South American "true frogs" were seperated from this taxon and placed into the new genus Lithobates (Frost et al., 2006; Crother, 2008; Collins and Taggart, 2009).  Scientific and standard English names follow Crother (2008).
