FWRI researchers are conducting a two-year survey to determine the current status of the Pine Barrens treefrog in Florida.
Population Assessment of the Pine Barrens Treefrog
The Pine Barrens treefrog (Hyla andersonii) is listed as a Species of Special Concern in Florida. Based on a recent biological status review, the Florida population will be recommended for delisting once a management plan is approved; however, the species’ present distribution and the condition of its habitat must be assessed to support the development of an effective management plan.
To address these information needs, Fish and Wildlife Research Institute researchers are conducting a survey in 2013 and 2014 for the Pine Barrens treefrog in four Florida counties – Santa Rosa, Okaloosa, Walton and Holmes. Biologists will replicate surveys conducted from 1978 to 1980 to determine the status and occurrence of the Pine Barrens treefrog. Population trends will be determined by calculating the percentage of historical locations that still have Pine Barrens treefrog populations. Biologists will locate the frogs by visiting breeding sites from April to August to listen for calling males. If insufficient rainfall results in conditions unsuitable for breeding during the first field season, researchers will extend the survey for a second season.
