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 purpose of the DNR Wildlife Health Program is to monitor wildlife populations for diseases, to provide information to support management decisions based on accurate information, and to minimize negative ecological, recreational, and economic impacts.
Common carp, introduced from eastern Europe over a century ago, are an invasive species in Minnesota that adversely affect water quality and aquatic communities, particularly in shallow lakes and wetlands. While solutions for suppressing common carp reproduction and abundance are emerging, controlling the movement of common carp, and therefore preventing reinfestation, has so far proved difficult.
Deep, cold-water lakes have different physical properties and support different wildlife than their more numerous shallow counterparts. The Minnesota Department of Natural Resources (DNR) is using this appropriation to conduct a study that will help identify, monitor, and predict the consequences of climate change and land use changes on water quality, habitat dynamics, and fish populations in deep, cold-water lakes.
The Minnesota County Geologic Atlas program is an ongoing effort begun in 1982 that is being conducted jointly by the University of Minnesota's Minnesota Geological Survey and the Minnesota Department of Natural Resources (DNR). The program collects information on the geology of Minnesota to create maps and reports depicting the characteristics and pollution sensitivity of Minnesota's ground-water resources.
Increasing energy conservation and efficiency in residences can play a significant role in Minnesota's goals for energy savings and carbon emissions reductions. The Center for Energy and Environment (CEE), a Minneapolis-based nonprofit organization, is using this appropriation to develop and implement innovative residential energy efficiency programs. Programs will be demonstrated in eight cities: Apple Valley, Austin, Duluth, Minneapolis, Owatonna, Park Rapids, Rochester, and St. Paul.
Overall Project Outcome and Results
DNR spent $140,689 to continue on-site field investigations to accelerate management of shallow lakes and adjacent wetland complexes and support the accomplishments of Ducks Unlimited through HCP 2c and 3c. Temporary field personnel (1 full time and up to 6 temporary) documented shallow lake habitat occurrence and quality. Habitat surveys were conducted on 171 lakes within seven HCP project areas. The lakes surveyed totaled over 82,831acres. The surveys were distributed more broadly than in the past with:
OVERALL PROJECT OUTCOME AND RESULTS The goal of this project was to improve habitat for waterfowl and other species that utilize wetlands on the Leech Lake Reservation in addition to analyzing a long term wild rice data set to determine if waterfowl numbers are influenced by rice abundance. A number of techniques were utilized to accomplish this work.
This appropriation is enabling Ducks Unlimited to help state and federal wildlife conservation agencies protect and restore shallow lakes for waterfowl. Conservation easements will be acquired on approximately 150 acres of privately owned shoreland and up to 60 acres of lands previously converted for cropping will be restored back to wildlife habitat. Lands being considered for permanent protection in this round of funding are located in Beltrami, Douglas, Freeborn, Grant, Meeker, Pope, Stearns, Swift, and Wright counties.
With this appropriation, the Minnesota Land Trust plans to protect approximately 500 acres of critical shoreline habitat along Minnesota's lakes, wetlands, rivers, and streams by securing permanent conservation easements and dedicating funds for their perpetual monitoring, management, and enforcement. Lands being considered for permanent protection in this round of funding are located in Becker, Beltrami, Blue Earth, Itasca, Kandiyohi, Lac Qui Parle, Le Sueur, Otter Tail, Pope, and Wabasha counties.
With this appropriation, the Minnesota Land Trust plans to protect 150 acres of high quality forest, prairie, or wetland habitat by securing permanent conservation easements and dedicating funds for their perpetual monitoring, management, and enforcement. Lands being considered for permanent protection in this round of funding are located in Anoka, Carver, Goodhue, Hennepin, Isanti, Washington, and Wright counties.
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.
