To address the problems caused by invasive species, the 1991 Minnesota Legislature directed the Minnesota Department of Natural Resources (DNR) to establish the Invasive Species Program. The program is designed to implement actions to prevent the spread of invasive species and manage invasive aquatic plants and wild animals (Minnesota Statutes 84D).
The three primary goals of the DNR Invasive Species Program are to:
1. Prevent the introduction of new invasive species into Minnesota.
2. Prevent the spread of invasive species within Minnesota.
The Minnesota County Biological Survey (MCBS) is an ongoing effort begun in 1987 by the Minnesota Department of Natural Resources (DNR) that is systematically surveying, county-by-county, the state's natural habitats. The effort identifies significant natural areas and collects and interprets data on the status, distribution, and ecology of plants, animals, and native plant communities throughout the state. Through 2009 surveys have been completed in 74 of Minnesota's 87 counties and have added nearly 17,000 new records of rare features to the DNR's information systems.
Earthworms are common throughout much of Minnesota, but few realize that they are not native to the state and were in fact introduced from Europe and Asia. Earthworms are invasive in Minnesota and have been shown to have large and potentially irreversible impacts on hardwood forest biodiversity and regeneration. As dispersal by human actions is the primary means of introduction and spread of invasive earthworms, there exists great potential to arrest the current spread of earthworms already present and prevent the introduction of additional species.
An emerging practice called "precision conservation" aims to maximize conservation benefits by considering the value of lands in terms of the interconnected systems of which they are a part. By compiling and integrating multiple types of data layers and analysis that are available today, conservation professionals can use the best and most precise information available to identify, prioritize, and guide conservation efforts.
