- Invasive species have negative ecological, economic, social and public health impacts. They have been widely identified as a serious threat to global and local biodiversity. Once established, they often out-compete native species for limited resources such as food and habitat, alter and damage existing habitat, displace native species and in some cases prey directly upon native species. Their impacts are found in our waterways, along our roadsides, in our wilderness areas and in both rural and urban communities. The Michigan Department of Natural Resources recognizes these threats and is working hard to prevent new invasions, limit the spread of existing invasions and limit their associated impacts.
Invasive Species of the Month
Chinese Yam (Dioscorea oppositifolia) The Chinese yam is a perennial vine native to Asia. The plant was introduced to the United States in the 1800's as a food source and is highly valued in traditional Chinese medicine. Since introduction, the Chinese yam has spread to 16 states, where it suppresses native ecosystems and reduces plant diversity. Despite the aggressive, invasive nature of the Chinese yam, the plant is still widely available as an ornamental. Chinese yam has not yet been found in Michigan; however sightings have been confirmed in Indiana, Illinois and Ohio. > More
