Invasive Species

The Invasive Species Program is a critical initiative within the Michigan Department of Agricultural and Rural Development dedicated to protecting our state’s natural resources, agriculture, and economy from the harmful impacts of invasive plants, pests, and pathogens. An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan's economy, environment, or human health.

Our program focuses on early detection, rapid response, and management of invasive species through a collaborative approach involving Quality of Life state agencies (DNR and EGLE), federal partners, local governments, tribal communities, and the public. By leveraging science-based strategies and community engagement, we aim to:

Prevent introductions of invasive species through education and outreach.
Detect and identify new infestations quickly using advanced diagnostics and monitoring.
Respond rapidly to contain and eradicate invasive species before they spread.

The program also supports research, policy development, and public awareness campaigns to ensure that stakeholders understand the risks and take proactive measures. Together, we can safeguard Michigan’s forests, waterways, agricultural lands, and biodiversity for future generations.
