This recently released, two-volume publication from the US EPA includes workshop reports and information on the effects of nonindigenous species (e.g., the zebra mussel, chinese mitten crab, the leafy spurge) on ecosystems and human health. The second volume (64 pages), A Landscape in Transition: Effects of Invasive Species on Ecosystems, Human Health and EPA Goals, covers such topics as municipal-industrial water supply, stream runoff, and recreation and tourism in the context of nonindigenous, invasive species. The second volume also presents statements on direct health risks to humans from water-borne invasive species as well as health risks from pesticides used against exotic plants. Other sections discuss Hawaiian biodiversity, preserving native flora and fauna on public lands, and ecosystem stability. The volumes can be downloaded in .pdf format.
