Invasive Species

About Invasive Species

An invasive species is any species that is introduced (non-native) to an area, whether purposefully or by accident and does or is likely to cause economic or environmental harm or harm to humans. It is important to note that not all non-native species are harmful. Thus, not all introduced (non-native) species are considered invasive species.

A large number of plants have been introduced to different ecosystems over the years. Often, invasive species can out-compete native plants for nutrients, water, and sunlight due to a lack of natural predators. Without the evolving checks and balances in an ecosystem, invasive species can colonize natural or disturbed areas. The loss of native plants is a serious concern because they are our wildlife's food source and habitat. The term invasive species does not only apply to vegetation; it is also used to describe certain insects, such as emerald ash borer, and pathogens, such as Dutch elm disease.
