With only 1% of Minnesota’s native prairie remaining, many prairie plant and animal species have dramatically declined. Of the 12 butterfly species native to Minnesota prairies, two species, the Poweshiek skipperling and the Dakota skipper, have already largely disappeared from the state and are proposed for listing under the U.S. Endangered Species Act despite being historically among the most common prairie butterflies and having their historic ranges concentrated in Minnesota.

Native to the western United States and Canada, mountain pine beetle is considered the most devastating forest insect in North America. Trees usually die as a result of infestation and an unprecedented outbreak in the west is currently decimating pine forests there. While mountain pine beetle is not presently believed to reside in Minnesota, there are risks posed by an expanding species range resulting from warming climate and the potential for accidental introduction via lumber imports from infested areas.

Northern white cedar wetland plant communities provide unique ecological, economic, and wetland functions, including high value timber, long-term carbon storage, winter refuge for deer and other wildlife, wildlife habitat, and thermal buffering for brook trout streams. However, these plant communities have been declining in Minnesota for decades mostly as a result of development impacts. The Minnesota Board of Water and Soil Resources is using this appropriation to continue efforts aimed at improving the quantity and quality of white cedar wetland plant communities in Minnesota.
Aquatic invasive species are a threat to the ecology and the recreational and economic viability of Minnesota’s water resources. When an invasion is confined to a distinct lake or wetland, local government units will implement localized plans to address invasions. However, when a water body crosses jurisdictions, such as with river systems, to be effective a more coordinated, regional approach is necessary that is more attuned with the natural pathways for invasive species.
Excess nutrients are among the most common impairments of water resources in the Red River Basin, as well as the rest of Minnesota. About 80% of the land use in the Red River Basin is for agricultural cropland and over 90% of phosphorus and nitrogen found in rivers and streams in the area originate from nonpoint sources, such as cropland. Excess nutrients are also one of the most difficult impairments to correct.
Pollinators play a key role in ecosystem function and in agriculture, including thousands of native plants and more than one hundred U.S. crops that either need or benefit from pollinators. However, pollinators are in dramatic decline in Minnesota and throughout the country. The causes of the decline are not completely understood, but identified factors include loss of nesting sites, fewer flowers, increased disease, and increased pesticide use. Developing an aware, informed citizenry that understands this issue is one key to finding and implementing solutions to counteract these factors.
Sandhill cranes have expanded their range in Minnesota and elsewhere and as populations have expanded several states, including Minnesota, have initiated sandhill crane hunting seasons and other states are considering doing the same. Partially this is in response to increasing complaints of crop degradation by sandhill cranes.
Though many parts of the Twin Cities metropolitan area are urbanized, there are also has large areas of natural lands that continue to serve as important habitat for fish, wildlife, and plant communities. However, pressure on these remaining lands continues to intensify as population and development pressures increase.
