Shallow Lakes and Wetlands Enhancements Phase 11
Funding through this appropriation enhanced 8,359 acres of wetland habitat. Included in this work were six infrastructure projects that enhanced 871 acres and a Douglas County wetland restoration was done in cooperation with Pheasants Forever. Wetland management actions by the Region 1 Roving Habitat Crew enhanced almost 7,500 wetland acres through work on prescribed burns, herbicide applications, and removal of woody vegetation. Survey and design work in Rice County gathered information for possible future construction. The Wetland Management Program was initiated through this appropriation and Shallow Lakes Program staff continued their valuable assessments and habitat project work.
ML19 Accelerated Shallow Lake and Wetlands Enhancements Phase 11 accomplishments include engineering and construction of individual projects, a stand-alone engineering project, specific wetland enhancement actions by the Roving Habitat Crew, and Wetland Management Program and Shallow Lakes Program assessment and project work.
Engineering and Construction Projects - Projects were undertaken to provide shallow lake and wetland enhancement totaling 871 acres through the engineering and construction of water control structures and other infrastructure at six project sites. The DNR cooperated with Pheasants Forever in restoring a Douglas County wetland. No acres are being reported by the DNR for this restoration, as Pheasants Forever will report them.
Stand-alone Engineering: Shallow lake and wetland projects can be complex and require detailed surveys and engineering. Stand-alone engineering projects provide the initial work to guide future construction, establish detailed cost estimates, and identify potential issues. One project in Rice County had this work done through this appropriation. Work is already underway to use this information to move ahead with construction.
Management Actions: Active management of shallow lakes and wetlands to enhance habitat involves a number of activities that promote management of vegetation (removal of undesirable vegetation or promoting desired vegetation), management of water levels to promote a desired condition, or removal of detrimental fish species. Nine projects totaling almost 7,500 acres were conducted and involved prescribed burning of wetlands, removal of woody vegetation, and herbicide applications.
Roving Habitat Crews: Roving Habitat Crews are teams of highly trained staff who are equipped to perform habitat enhancement projects on public lands. Funding from this appropriation was provided to the Region 1 Roving Habitat Crew to enable it to perform wetland enhancement activities through the addition of two roving crew members and their associated costs for three fiscal years. Typical wetland enhancement activities undertaken by Roving Habitat Crews include prescribed burns of wetlands, removal of invasive species and trees, and support of shallow lake drawdowns. Of special note, Roving Habitat Crews provide the critical ground support staff for aerial cattail spraying. The Roving Habitat Crew supported by this appropriation was active in this work and the resulting acres will be reported in the Final Report for the appropriation that funded the helicopters and herbicide costs. This work would not be possible but for the critical role played by the Roving Habitat crews.
Wetland Management Program/Shallow Lakes Program: The Wetland Management and Shallow Lakes Programs are single-focused programs that perform habitat assessments to identify wetlands and shallow lakes with poor habitat and in need of management, identify type of management possible, then implement management. Finally, follow up assessments are done to evaluate management success and formulate adaptive management strategies. These specialists also work with NGOs to implement management. These efforts on wetlands and shallow lakes requires both expertise in permitting and on-the-ground implementation and could not be done without these specialized staff.
$3,541,000 the first year is to the commissioner of natural resources to enhance and restore shallow lakes and wetland habitat statewide. A list of proposed land restorations and enhancements must be provided as part of the required accomplishment plan.
A statewide review of Species of Greatest Conservation Need (SGCN) found that wetlands are one of the three habitat types (along with prairies and rivers) most used by these species. The almost 5,000 acres of wetland enhancement will provide wetland management actions identified to support SGCN, including reversal of wetland degradation and control of invasives. In the Minnesota County Biological Survey description of the marsh community, special attention is given to two issues faced in Minnesota marshes - stable high water levels that reduce species diversity, often to a point at which a monotypic system evolves, and the "invasion of marshes by the non-native species narrow-leaved cattail" and its hybrids. Both of these issues were directly addressed by the major cattail control activities involving the Roving Habitat Crew, along with water level management that will now be possible through because of newly installed wetland infrastructure projects.
