Louisiana crawfish, cheatgrass, Russian thistle, Hottentot figs, rats, and sweet fennel. These and dozens of other seemingly benign flora and fauna have become some of the worst culprits in the destruction of ecosystems and native wildlife in the American Southwest and Baja California. Although widely publicized threatsasuch as pollution, land development, changes in the atmospheric condition, fire, and droughtaare frequently credited with posing the greatest danger to indigenous animals and plants, invasive species are quickly becoming a far more insidious peril to the survival of native wildlife. A result of both accident and human intervention, the frequency with which exotic species are being introduced into nonnative environments is increasing at an alarming rate. In Unnatural Landscapes, Ceiridwen Terrill combines lucid science writing with first-person tales of adventure to provide a compelling introduction to invasion ecology and restoration management. Traveling aboard her trusty kyak, The Grebe, Terrill brings readers on a firsthand tour of various aislandsa in the Southwest and Mexicoaboth actual islands and self-contained habitat communities. From the islands of Anaho, Santa Cruz, and Anacapa to Isla TiburA3n in the Sea of Cortez, Mexicali irrigation canals, and Pyramid Lake, Terrill takes an in-depth look at the damage that invasive species cause. Drawing on field observations, research, and interviews with scientists, resource managers, and local residents, this book provides readers with the background and knowledge they need to understand and to begin combating what is quickly becoming the most important environmental crisis facing the fragile ecosystems of the Southwest.
