During the 1970s, John D. Lynch and his students conducted extensive fieldwork in Nebraska to complete a herpetological survey begun by George E. Hudson nearly three decades earlier. During the late 1990s, the author revisited the work done by Lynch to address questions of amphibian population declines at the state level in Nebraska since the 1970s. Among his findings: the majority of commonly occurring amphibian species have declined at the state level; declining populations of amphibians occurred in at least three of four ecological regions, with the eastern third of the state (Zone 1) experiencing the greatest declines; occurrences of declines are not limited to those species with specific breeding habitat requirements, but are seen even in breeding site generalists; there is an alarming decrease in the proportion of ponds that were historically occupied by amphibian larvae.
