Wetland Invasive species - Non-regulated animals

Reed Canary Grass
Reed canary grass is an invasive species that dominates almost half a million acres of Wisconsin’s wetlands.

Invasive species may be the greatest threat to the long-term health and sustainability of Wisconsin's wetlands. Human activities such as urban development, farming, recreation and gardening have resulted in the introduction of many non-native plant and animal species to the state. In some cases those species end up competing with native species and can take over large areas of land. For instance, reed canary grass dominates almost half a million of Wisconsin wetland acres.
