DNR Grassland Enhancement Ph X
We restored and enhanced a total of 15,577 grassland acres with 239 projects on Wildlife Management Areas, Scientific and Natural Areas, and Native Prairie Bank easements.
We select projects using a number of criteria and reviews to make sure the DNR were spending these funds in the best and most productive ways. We can summarize our results in the following table.
Brome conversion 6
Interseeding 60
Grassland restoration 838
Prescribed Fire 10,550
Herbaceous Invasive Control 346
Goat Browsing - woody removal 71
Woody Removal 3,492
TOTAL 15,577
This appropriation involved the Southwest Roving Crews. These Crews allow the DNR to be very flexible. While they have a list of projects to work on, they can also respond fairly quickly if there's an enhancement opportunity shows up. For instance, a short dry period in a part of the state may allow them to conduct a late summer prescribed fire which was not in any of the original work plans. Roving Crews have begun experimenting with different burn seasons. The DNR and partners continue to host field days each summer to learn about management practices such as prescribed fire, conservation grazing, etc. We also regularly review the scientific literature to make sure we are applying the most up to date techniques in our management. We were also able to continue our experimenting with goat browsing in the SE to control buckthorn. SNA staff will monitor these sites over the coming years. This may provide a way to reduce chemical use and integrate some new and emerging agricultural practices, goats, into habitat management for the benefit of wildlife and the agricultural economy.
The DNR has traditionally focused on game species such as pheasants. However, there is more and more interest in pollinators and biodiversity. Fortunately, just about every study out there shows that management and restoration for pollinators and songbirds often creates the best habitat for game species. Diverse, healthy, productive habitat is good for a wide range of species. These projects can also increase the amount of carbon absorbed and stored by the plants and soils on these sites. All of these projects, directly or indirectly, fit within the state's Climate Action Framework and other climate related activities. As we continue to use these funds, costs for projects will probably increase. In the early years of these funds, we completed a number of simpler or easier projects, the low-hanging fruit. Now we are left with the larger and more challenging projects.
In our budget table, we prorated our budget for individual projects by the acres accomplished. Staff funding was combined into one value. Identifying funding for each position would be an accounting challenge so staff funds were combined by DNR Division.
$4,007,000 the second year is to the commissioner of natural resources to accelerate restoration and enhancement of prairies, grasslands, and savannas in wildlife management areas, in scientific and natural areas, on lands in the native prairie bank, in bluff prairies on state forest land in southeastern Minnesota, and in waterfowl production areas and refuge lands of the United States Fish and Wildlife Service. A list of proposed land restorations and enhancements must be provided as part of the required accomplishment plan.
Prairie habitats once covered one-third of the state but presently less than 2% remain. Native prairie, other grasslands that provides habitat for wildlife, and wetlands are key components of functional prairie landscapes that have the capacity to adapt to changing environmental conditions. While these appropriation only added 838 acres of grassland acres to the state through restoration, these funds enhanced a much larger area. Put another way, we restored and enhanced 24.3 square miles with these funds. That would be a strip of grassland habitat that would equate to a quarter mile wide stretching from Moorhead to Alexandria.
None of this work was targeted at a specific species of wildlife. We used that approach that diverse productive habitats benefit a wide variety of both game and non-game wildlife species as well as any threatened or endangered species. In our restorations, we use very diverse seed mixes. This is obviously beneficial for pollinators. However, all those insects also create a food base for a large number of wildlife species. The structural diversity all those plant species create in the habitat allow every species to find an ideal niche in the grass as well as accommodates different life history stages of wildlife.
