Welcome: Invasive species: Do they matter?
Description: Biodiversity--the variety of different species present locally, regionally, or globally--is generally thought to be threatened. Ecologists regard habitat loss as the principal threat, with pollution and overexploitation (hunting, collecting) also involved. In this webquest you will explore the role of invasive species, first distinguishing them from other nonnatives.
