Between 1980 and 1994, 586 individuals of 20 native reptile and amphib
ian species were evaluated at a wildlife rehabilitation facility in Du
Page County, Illinois (USA). On examination, 48% of reptiles and 52% o
f amphibians were injured, and 2% of each class were diseased; remaini
ng animals were uninjured. The most frequent causes of injury to repti
les were automobile collisions (55%), ingestion of fishing tackle (19%
), and domestic animal attacks (8%). Automobile collisions (38%), lawn
and garden accidents (33%), and pet collection (19%) were the most fr
equent causes of injury to amphibians. We released 354 reptiles and 54
amphibians into appropriate habitat available in local forest preserv
es, representing case release prevalences of 84% and 68% for each clas
s, respectively.
