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 first volume (127 pages), Region/ORD Nonindigenous Species Reports, contains excerpts from the Mid-Atlantic and Great Lakes Regional Nonindigenous Invasive Species Workshops, and the Wetland/ Riparian Nonindigenous Invasive Species Workshop, among others, covering issues such as regulating ballast water, chemical control of invasives, and coordinating federal, state, and local agencies. The volumes can be downloaded in .pdf format.
