What are invasive species? They are non-native species that spread easily, displacing native plants or animals. Why are they harmful? They out-compete native species and as a result, decrease the variety of plants and wildlife.

How do invasive species affect the White Clay? Currently, there is an abundance of plants and animals native to the region and the White Clay Creek, including 33 species of small mammals, 21 species of fish, 27 species of reptiles and amphibians, and over 90 species of breeding birds.  Invasive plants, fish, and other organisms are harmful in the White Clay because they take over native species' habitat and decrease the variety of species. For example, oriental bittersweet is an invasive species in our region. Its out-of-control growth can smother and eventually kill the tree or shrub on which it grows.  An increase in invasive species in the White Clay would eventually decrease the White Clay's variety of plants and wildlife.
