Abstract
Sampling conducted from 1970 to 1980 indicates that ranges of about 69% of the species and subspecies of amphibians and reptiles found in the state are receeding. Of Iowa's 76 forms, 15% are considered in danger of extinction in the state, 22% threatened with ultimate extinction if corrective action is not taken, and 32% are declining. Only 8% have shown improvement in recent years and the remaining 22% appears relatively stable. Further studies are needed to precisely determine the status of each form and outline protective strategies.
