The occurrences of contaminants including antibiotics, other pharmaceuticals, and personal care products in the environment have gained increasing attention in recent years because of their potential health and ecological impacts. However, serious gaps remain in our understanding of these contaminants and the significance of the threats they may pose, such as to drinking water. Through this appropriation scientists at the University of St.
Over a three-month period in 2010, approximately five million barrels of oil was spilled into the Gulf of Mexico causing extensive damage to marine and wildlife habitats and resulting in significant losses in fish and wildlife populations. A number of Minnesota's migratory bird species spend parts of their lives in the areas impacted by the spill and impacts on their populations in the state could become evident over time.
Garlic mustard is a non-native, invasive plant species that is severely threatening native plant communities and degrading wildlife habitat in forest and riparian zones throughout the state. The plant is considered the highest priority species for development of long-term management solutions such as biological control, which involves using natural enemies of a non-native species from its native region to control or reduce the impact of the species in the areas where they are invasive.
The purchase of conservation easements—restrictions on land use that protect natural features while keeping land in private ownership—has proven to be an effective means to protect land at a lower initial cost than full state ownership. However, once an easement is purchased there are ongoing stewardship, monitoring, and enforcement responsibilities necessary to ensure the terms of the agreement between the easement holder and the landowner are met.
Grassland ecosystems evolved to depend on periodic disturbances, such as fire and grazing, to maintain their health and stability. Periodic disturbances help control invasive species, add nutrients back into the soil, germinate plant seeds, enhance wildlife habitat, and more. In Minnesota habitat managers have used fire as a disturbance tool for decades but the use of grazing has been much rarer, mostly because of a lack of necessary infrastructure such as fencing.
Appropriations to non-state entities must be made through a formal contract with a state entity that manages all of the funds for the project on a reimbursement basis. This appropriation to Minnesota's Department of Natural Resources (DNR) funds the expenses incurred by the DNR in contracting, contract management, and expense re-imbursement for most of the Environment and Natural Resources Trust Fund appropriations made to non-state entities, including both new projects funded during the biennium and existing projects funded in previous bienniums.

Terrestrial invasive plants such as buckthorn, wild parsnip, garlic mustard, and others are becoming widespread threats throughout many sites in Minnesota. Present chemical and mechanical control methods tend to be costly, effective only in the short-term, or have other negative environmental impacts. However, an alternative practice of using grazing animals for invasive species management is used successfully in many parts of the western United States.
The Minnesota County Geologic Atlas program is an ongoing effort begun in 1979 that is being conducted jointly by the University of Minnesota’s Minnesota Geological Survey and the Minnesota Department of Natural Resources (DNR). This portion, called Part B and conducted by the DNR, analyzes water samples to understand water chemistry and sensitivity to pollution.
Asian carp pose a real and serious threat to Minnesota’s aquatic ecosystems. While there are a few instances of individual carp being found in Minnesota waters, including the Mississippi and St. Croix Rivers, it is not presently believed that there are significant established populations in the state. In order to quickly and effectively respond to threats posed by Asian carp in the future, though, detailed information about the fish themselves is needed.
Minnesota’s natural resource professional workforce is much less diverse than its citizenry and many other professional fields. The benefits of a more diverse workforce are many, including the ability of organizations to increase innovation and creativity, attract higher qualified candidate pools, and ensure services that meet the diverse interests and needs of all citizens.
Climate change has and will have profound effects on Minnesota’s economy, agriculture, tourism, and natural resources. While climate change is often discussed in the broader contexts of its potential impacts at a national or international level, research has shown that climate change education and behavior change happens more effectively when the issue is made local and relevant.
The average Minnesotan and even most natural resource managers are not skilled in plant identification, yet the ability to positively identify plants is crucial to a number of conservation activities, including identifying areas that need protection, recognizing new or existing invasive species, monitoring restoration projects, and delineating wetlands. The Minnesota Wildflowers project attempts to fill this need with a free web-based field guide ultimately aimed at providing profiles for each of the over 2,100 vascular plant species in Minnesota.
Endocrine-disrupting contaminants such as environmental estrogens have been found and studied in large lakes and streams and shown to exist at concentrations that have adverse effects on wildlife. However, very little is known about the sources and effects of environmental estrogens in small, shallow lakes. Preliminary data suggests that these compounds are present in shallow lakes and have an effect on the survival and reproduction of wildlife. Researchers at the University of St.
Woody biomass energy systems have shown themselves to offer more locally-based, stable energy supplies for some communities. Itasca Community College is using this appropriation to design a renewable energy system based on woody biomass that will serve as a demonstration and educational tool in the region.
Since 2000, a diverse group of partners has been collectively working in northwestern Minnesota on one of the largest prairie-wetland restorations in the world. Spanning 22,000 acres and adjacent to an additional 16,000 acres of public and private conservation land, the goal of the Glacial Ridge Project has been to demonstrate whether large-scale habitat restoration is a viable way to reduce flooding and improve water quality. Prior to beginning restoration efforts on the project, a comprehensive baseline hydrologic study of the area was completed by the U.S. Geological Survey (USGS).
These funds will enable Great River Greening to restore approximately 90 acres of permanently protected forests, savanna, prairie, and wetland habitat and 0.18 miles of shoreland habitat while engaging hundreds of volunteers in the stewardship of the Metropolitan area's remaining natural areas. Specific activities include invasive species control, seeding/planting, prescribed burning, and other associated activities.
With this appropriation, the Minnesota Land Trust plans to protect 100 acres of high quality forest, prairie, wetland, or shoreline 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 Chisago, Goodhue, Hennepin, Isanti, and Washington counties.
The Minnesota Valley National Wildlife Refuge Trust is using this appropriation to purchase a total of approximately 100 acres of land and donated to the U.S. Fish and Wildlife Service to expand the Minnesota Valley National Wildlife Refuge. Many benefits are anticipated from this project, including improved habitat connectivity, protection of native species, improved water quality in the Minnesota River, and increased public access to natural lands for activities such as hiking, hunting, and fishing. Restoration and management plans will be completed for all acquired lands.
A state Breeding Bird Atlas is a comprehensive systematic field survey of the occurrence, distribution, diversity, and breeding status of bird species within every region of a state. Atlases are mainly used to set conservation priorities, develop conservation plans, and guide habitat protection, restoration, and management efforts – in addition to being useful for recreational bird watching. Minnesota is one of only seven states in the country that has yet to complete a Breeding Bird Atlas.
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.
The Minnesota Biological Survey (MBS) is an ongoing effort begun in 1987 by the Minnesota Department of Natural Resources (DNR) that is systematically surveying, county-by-county, the state’s natural habitats. The effort identifies significant natural areas and collects and interprets data on the status, distribution, and ecology of plants, animals, and native plant communities throughout the state. To date, surveys have been completed in 81 of Minnesota’s 87 counties and nearly 20,000 records of rare features have been recorded.
Moose, one of Minnesota's prized wildlife species, are dying at much higher rates in Minnesota than elsewhere in North America. Recently observed increases in mortality rates amongst some moose in northeastern Minnesota have led to concern that the population there may be entering a decline like that seen in the northwestern part of the state, where moose populations fell from over 4,000 to fewer than 100 in less than 20 years. Additionally the specific causes of increased mortality amongst individual moose remain under investigation.
Prior to European settlement more than 18 million acres of prairie covered Minnesota. Today less than 1% of that native prairie remains, and about half of those remaining acres are in private landownership without any formal protection currently in place. Through this appropriation the Minnesota Department of Natural Resources will work with private landowners of high quality native prairie sites to protect remaining native prairie using a variety of tools. Approximately 200 acres are expected to be permanently protected through Native Prairie Bank conservation easements.
The groundwater contained in confined glacial aquifers provides clean drinking water to many Minnesota residents. An important factor affecting the long-term sustainability of these aquifers is how water infiltrates through clayey deposits of overlying glacial till, which act as barriers to contaminants but also limit water flow and aquifer recharge. Very little is actually known about the properties and infiltration of water through till, which hinders the ability to accurately define the sustainability of these aquifers.
Minnesota’s Scientific and Natural Areas (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 landforms, fossil remains, plant and animal communities, rare and endangered species, and other unique biotic or geological features. These sites play an important role in scientific study, public education, and outdoor recreation.

Over the past several years six environmental learning centers located around the state - Audubon Center of the North Woods, Deep Portage Learning Center, Eagle Bluff Environmental Learning Center, Laurentian Environmental Learning Center, Long Lake Conservation Center and Wolf Ridge Environmental Learning Center – have been implementing demonstrations of energy conservation, energy efficiency, and renewable energy on their campuses for use as educational tools for the thousands of students and visitors that come to the centers each year.
Oftentimes water conservation efforts are directed toward impaired waters. However, it is much more cost-effective to protect habitat and water resources before they become degraded. The Nature Conservancy is using this appropriation to create a broader, long-term, watershed-based framework for proactively protecting habitat and water resources in southeast MN, specifically the Cannon River and Zumbro River watersheds, before they become degraded.
Natural springs occur throughout Minnesota and provide critical services for the state, such as creating trout streams and cool water fisheries, sustaining base flows in streams, creating unique ecological habitats, and maintaining the integrity of aquatic ecosystems against invasive species. In order to protect springs and the groundwater-dependent resources that depend on them, though, it is important to understand spring locations and status – information that is currently lacking in many areas of the state.
Minnesota’s extensive state park and trail system, the second oldest in the country, is currently comprised of a total of 76 state parks and recreation areas and 13 state trails scattered throughout the state. Some of Minnesota’s state parks and trails have privately owned lands within the designated park boundaries or trail corridors. Purchase of these lands from willing landowners for addition to the state park and trail system makes them permanently available for public recreation and enjoyment and facilitates more efficient management.
Minnesota’s environment is changing in response to a variety of stressors – including population growth, residential development, industry, agriculture, invasive species, and climate change – and the state’s iconic lakes, and the goods and services they provide (e.g., fishing and water recreation), are an important part of what’s being impacted. To manage effectively for these changes it is important to understand how the state’s many lakes respond to these stressors.
Over the past 100 years, about half of Minnesota’s original 22 million acres of wetlands have been drained or filled. Some regions of the State have lost more than 90 percent of their original wetlands. The National Wetland Inventory, a program initiated in the 1970s, is an important tool used at all levels of government and by private industry, non-profit organizations, and private landowners for wetland regulation and management, land management and conservation planning, environmental impact assessment, and natural resource inventories.
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.
There has been a sharp decline in participation in outdoor recreation and education amongst youth, particularly in urban areas. Some argue that youth who have meaningful outdoor education experiences are more likely to become engaged in environmental stewardship and invested in outdoor resources as adults.
Wild bees are important for their pollination services and for their contribution to species diversity; for example, many prairie-grassland plant species require pollinators for seed production. However, while the importance of plant-pollinator interactions is well recognized, there are large gaps in our knowledge of Minnesota’s wild bees. The only statewide list of bee species was published in 1919 and it reported only 88 species, whereas it is currently estimated that there are approximately 350-400 native bee species in the state.
Wolves are a hot topic in Minnesota, with the public sharply divided on management issues such as wolf hunting. The complexity of the topic lends itself to a lot of misunderstanding and misinformation that is not always helpful to resolving the polarized debate.

Adoption of renewable energy technologies and energy conservation practices can contribute in a variety of ways to the environmental and economic health of rural Minnesota communities through costs savings and emissions reductions. Engaging and coaching students as the leaders in the process of implementing such practices provides the added benefit of increasing knowledge, teaching about potential career paths, and developing leadership experience.
Zebra mussels are an aquatic species that are invasive in Minnesota and severely threaten native fish and other aquatic species by disrupting food webs and damaging spawning habitat. Their range continues to expand within Minnesota lakes and rivers, where they are spread through the transporting of water, vegetation, or equipment from an infested water body. Once established zebra mussels are very difficult to control and there is an immediate need for safe and effective control measures to reduce their impacts in the state.
