All over the planet, organisms of many species are appearing outside of their natural habitatsoften carried by that particularly peripatetic species Homo sapiens. This book marks the first
comprehensive attempt to address problems posed by expanding populations of exotic plant and animal species in the Sonoran Desert and adjacent grasslands and riparian areas. It describes the arrival
and spread of non-native species as diverse as rats and saltcedar, covering both their impacts and the management of those impacts. It is estimated that as much as 60 percent of the vegetative
cover of the Sonoita Creek-Patagonia Reserve, the first Nature Conservancy area designated in Arizona, is dominated by exotic plants, and that introduced fish pose a recurrent threat to the native
fish of that area. Meanwhile at the Grand Canyon, invasives such as tamarisk, red brome, carp, and catfish are pervasive either in the Colorado River or in the patches of desert scrub along its
shores. Throughout the Sonoran Desert and adjacent areas, from islands in the Sea of Cortés to desert grasslands, some six hundred species of non-native plants and animals have become
established, with bullfrogs and Mediterranean grasses now common where they once never existed. The book brings together contributors from academia, government, and nonprofit organizations,
including such experts as Gary Paul Nabhan, Richard Mack, and Alberto Búrquez-Montijo. They review historic and even prehistoric origins of non-native speciesnot only exotic plants,
amphibians, and mammals but also insects, fish, and birds. They then examine significant problems in each major subregion and ecosystem and discuss control efforts. The volume contains the first
compiled list of more than 500 naturalized exotic species in the Sonoran region. Invasive species issues are rapidly emerging as major environmental concerns both locally and worldwide. This book
will assist professionalsecologists, conservation biologists, and policy makersinvolved in invasive species control in the Southwest and will be a rich resource for all concerned with
protecting native species and their habitats.
A valuable contribution to our understanding of how nono-native species are changing one of the world's great biological realms.
Systemics & Evolution
This book is an outstanding tool for understanding and addressing native species and habitat protection, and will become a standard resource.
Biological invasions are one of the hottest topics in contemporary ecology and conservation. . . . With this book in hand, both theoreticians and practitioners will be better armed to tackle the problem.
Progress in Physical Geography
A valuable contribution for anyone in this region attempting restoration in the face of exotic species, and will be a useful reference for those trying to analyze and understand the issue on a continental scale.
