What are invasive species?

Terrestrial invasive species (TIS) are non-native plants, animals, and other living organisms that cause (or are likely to cause) economic or environmental harm. 

These species are usually unintentionally spread by human activities from foreign ecosystems. Invasive species can establish very rapidly to out-compete native species and permanently alter habitats. 

Common buckthorn is one of the most established invasive species in Wisconsin.

Why protect native species?

Native species provide many benefits to an ecosystem. Most notably, native plants conserve water, improve soil health, and provide food for wildlife. Native species can create a more balanced ecosystem. 

Wildlife species have adapted to living in ecosystems with native vegetation. Native plants provide foliage, tubers, and fruit to wildlife that can effectively be digested.
