While natural areas are conservation lands that have been set aside for the purpose of preserving (or restoring) native plant and animal communities, they do require active management. One of the greatest management issues in natural areas is invasive plants.

Invasive nonindigenous species -- plants and animals that have been introduced to an ecosystem from someplace else -- are wreaking havoc around the globe. Because they did not co-evolve with species already in the ecosystem, they can profoundly disturb species interactions and ecosystem function.The state of Florida has one of the most severe exotic species problems in the country; as much as a quarter of many taxa in Florida are nonnative, and millions of acres of land and water are dominated by nonindigenous species. Strangers in Paradise provides an in-depth examination of the Florida experience and of the ongoing efforts to eradicate or manage introduced species. Chapters consider: natural disturbance and the spread of nonindigenous species case studies of insects, freshwater invertebrates, fishes, amphibians and reptiles, birds, marine invertebrates and algae, and mammals methods of managing nonindigenous species including ecological restoration, eradication, "maintenance control," and biological control management on public lands the regulatory framework including the role of the federal government as well as state authorities and responsibilities Strangers in Paradise is the first comprehensive volume to address a large, diverse region and the full range of nonindigenous species, the problems they cause, and the methods and impediments to dealing with them. Throughout, contributors emphasize solutions and relate the situation in Florida to problems faced by other states, making the book an important guide for anyone involved with control and management of invasive species.
