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.
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.
Minnesota's Scientific and Natural Area (SNA) Program is an effort to preserve and perpetuate the state's ecological diversity and ensure that no single rare feature is lost from any region of the state. This includes unique landforms, fossil remains, plant and animal communities, rare and endangered species, or other unique biotic or geological features. These sites play an important role in scientific study, public education, and outdoor recreation.
