Invasive and nonnative plants and animals

Welcome: Invasive and nonnative plants and animals
Description: Biodiversity is generally good. However, sometimes there are certain species that may not belong to an ecosystem. Such species are considered to be "nonnative" and can outcompete native species. In this webquest you will research an invasive organism and take a walk in a local greenspace to find an invasive plant.
