Declines in Canadian amphibian populations : designing a national monitoring strategy / Christine A. Bishop, Karen E. Pettit (editors). : CW69-1/76E-PDF

"Since 1989, there has been a growing realization that amphibian populations have been declining at an alarming rate. For many years before that, direct habitat loss such as infilling of wetlands was acknowledged as the major causative factor of a general loss of global biodiversity, including a loss of absolute and species numbers in the class Amphibia. However, the recent formation of the Declining Amphibian Populations Task Force (DAPTF) by the Species Survival Commission of the World Conservation Union (IUCN) was triggered by the disappearance of or drastic decreases in some populations of amphibians where suitable habitat appeared to remain, which indicated that things were even worse than we had thought. Scientists could not explain these declines because worldwide, and Canada wide, there has been a dearth of monitoring of changes in amphibian populations and stresses that regulate those populations"--Introd.
