Book Description
The book describes results of 20 years of study of the ecology and management of Sacramento's bridge-nesting Purple Martin population. This is the last population of this California Species of Special Concern that remains in the state's Central Valley. Contents include population status, habitat requirements, and evaluation of management actions taken on behalf of the species. Various factors that could be responsible for the dramatic 88% population decline are evaluated in detail. A population model uses information on population size and survival estimates from banding studies to identify the cause of decline as inadequate reproduction, which is tied to the dramatic increase in use of neonicotinoid insecticides in surrounding urban and agricultural lands. The document identifies needed conservation measures and detailed land use planning guidelines for planning, design, environmental analysis, and construction to prevent disturbance of nesting martins and degradation of their habitat by urban development projects. The book also includes a number of accessible and entertaining sidebar explorations on how this long-term research project was conducted, how Western Purple Martins differ from their more abundance eastern counterparts, why martins are nest in colonies, and other topics of general reader interest.

Book Description
One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.
