During 1997, collections of larval amphibians were made at 130 sites in Nebraska. Collections were made during 1 June - 16 July, so as to replicate earlier samples taken by John D. Lynch in 1971-75. The same sites that Lynch surveyed were sampled in the recent survey, unless they were no longer present or accessible, in which case a replacement site within 1.6 km was sought. The overall objective of the study is to test the hypothesis that amphibian populations have declined in Nebraska. Results reported here indicate the species found in each county where collections were made.
This study was supported in part by the Grasslands Ecosystem Initiative, Northern Prairie Wildlife Research Center, U.S. Geological Survey-Biological Resources Division, Jamestown, North Dakota.
