In cities, towns, and villages, between buildings and parking lots, streets and sidewalks, and polluted streams and rivers, there is ever less space for the "natural," the plants and animals that once were at home across North America. In this first book-length study of the subject, Lowell W. Adams reviews the impact of urban and suburban growth on natural plant and animal communities and reveals how, with appropriate landscape planning and urban development, cities and towns can be made more accommodating for a wide diversity of species, including our own.
Soils and ground surface, air, water, and noise pollution, space and demographics are among the urban characteristics Adams considers in relation to wildlife. He describes changes in the composition and structure of vegetation, as native species are replaced by exotic ones, and shows how, with spreading urbanization of natural habitats, the diversity of species of plants and animals almost always declines, although the density of a few species increases. Adams contends, however, that it is possible for a wide variety of species to coexist in the metropolitan environment, and he cites a growing interest in the practice of "natural landscaping," which emphasizes the use of native species and considers the structure, pattern, and species composition of vegetation as it relates to wildlife needs.
Urban habitats vary from small city parks in densely built downtowns to suburbs with large yards and considerable open space. Adams discusses the opportunities these areas—-along with school yards, hospital grounds, cemeteries, individual residences, and vacant lots—-provide for judicious wildlife management and for the salutary interaction of people with nature.
