Historically the management of public lands from a multiple use perspective has led to a system that emphasizes those habitat components or faunal elements that primarily resulted in some sort of definable economic value. While this often benefitted other species that were not even considered in the original prescriptions, it also negatively impacted others. We no longer can afford to take this simplistic view of ecosystem management. We need to use a more holistic approach where ecological landscapes are considered as units, and land management practices incorporate all elements into an integrated policy. This includes examining the impacts of proposed land uses on amphibian, reptile, and small mammal populations.

Amphibians and reptiles (herpetofauna) are a significant but much-neglected component of the natural economy of the province of Alberta. The Amphibians and Reptiles of Alberta, Second Edition continues both as a field guide and a comprehensive natural history, builds on the strengths of the first with a richly illustrated text and colour photographs of the species taken by renowned wildlife photographer Wayne Lynch. The Amphibians and Reptiles of Alberta, First Edition won an Emerald Award for Environmental Excellence and an award from the Book Publishers Association of Alberta. This second edition has been thoroughly revised and updated. Nomenclature has been changed to reflect current thinking in the field. New photographs have been added, and maps and illustrations have been updated. This is the essential reference for Alberta herpetofauna.

As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.
