This project will accelerate production of County Geologic Atlases (part A). This is a set of geologic maps and associated databases for a county that facilitate informed management of natural resources, especially water and minerals.

Aquatic invasive species pose critical ecological and economic challenges for the entire state and beyond. They can cause irreparable harm to fisheries and aquatic habitat as well as damage to infrastructure. The problems posed by aquatic invasive species continue to grow as existing infestations expand and new exotic species arrive, most of which are poorly understood. New ideas and approaches are needed to develop real solutions.
Large deposits of copper, nickel, cobalt, and other minerals in northeastern Minnesota could provide huge economic and employment benefits to the state while becoming an important source of important metals for the country. However, the mining required to extract them could have significant water quality impacts in a region that includes the Boundary Water Canoe Area Wilderness and other environmentally sensitive watersheds.
Bees play a key role in ecosystem function and in agriculture, including more than one hundred U.S. crops either need or benefit from pollinators. However, bee pollinators are in dramatic decline in Minnesota and throughout the country. One of the potential causes appears to be a scarcity of bee-friendly flowers, particularly in urban areas, which is leading to nutritional deficiencies, chronic exposure to pesticides, and debilitating diseases and parasites.
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 A and conducted by the Minnesota Geological Survey, collects geologic information to produce maps and databases that define aquifer boundaries and the connection of aquifers to the land surface and surface water resources.
The Emerald Ash Borer (EAB) has been decimating ash throughout the Great Lake States and is currently advancing into Minnesota, threatening the future of the ash forests that occur across much of the state. Of particular concern is the impact EAB will have on the ecology and functioning of black ash swamps, which cover over one million acres in Minnesota and represent the state’s most common ash forest type. Black ash trees grow and thrive in swamps and occupy a unique wet niche where few other tree species grow.
Over 527,000 acres of unmanaged woodlands are being used for livestock grazing throughout Minnesota. Managing these grazed woodlands based on the use of best management practices can provide environmental and economic opportunities, including improved water quality, maximized forage production, and higher-quality timber. The best management practices involved are commonly used in other parts of the country with other types of ecosystems, but have not been widely adopted in Minnesota due to a lack of knowledge and experience with implementing them within the ecosystems of Minnesota.
Minnesota has 9.5 million acres of public forest lands that play an important role in sustaining Minnesota’s environment and economy. The policies and programs used by public timber sale programs can impact post-harvest ecological conditions and have pronounced effects on the composition, structure, and productivity of the forest in the future. Additionally, timber harvesting revenues play an important role in economic activity, employment, and tax revenue.
Lake Superior, the world’s largest freshwater lake by surface area, is amongst Minnesota’s greatest natural resources providing drinking water, shipping, recreation, and tourism. Recently the lake has been undergoing significant changes including increasing water temperatures, decreasing ice cover, increasing nutrient loads, decreasing biological productivity, increasing invasive species, and changes in species abundance and distribution. The reasons behind these changes and the interactions amongst them are not well understood.
Elms were once a very widespread tree in Minnesota and amongst the most common and popular in urban landscapes due to their size, shading capability, and tolerance of pollution and other stresses. Over the past five decades, though, Dutch elm disease, an exotic and invasive pathogen, has killed millions of elms throughout the state. However, scientists at the University of Minnesota have observed that some elms have survived the disease and appear to have special characteristics that make them resistant to Dutch elm disease.
The Soudan Iron Mine near Ely, Minnesota is no longer an active mine and is now part of a state park, as well as the home to a state-of-the-art physics laboratory at the bottom of the mine. The mine has also been discovered to contain an extreme environment in the form of an ancient and very salty brine bubbling up from a half-mile below the Earth’s surface through holes drilled when the mine was active. Strange microorganisms – part of an ecosystem never before characterized by science – have been found living in the brine.
Minnesota has 15.9 million acres of forest land managed by a variety of county, state and federal agencies, and private landowners for timber production, wildlife habitat, and ecological considerations. Forest managers rely on inventory data to make effective planning and management decisions. Because forests are continually changing through natural and human processes, forest inventory data is periodically updated. However, doing so is an expensive and time-consuming endeavor and, as a result, much of Minnesota’s forest inventory data is currently out of date.
The Emerald Ash Borer (EAB) is an invasive insect that has been decimating ash trees throughout the Great Lakes states. It was first discovered in Minnesota in 2009 and is now found in four counties (Hennepin, Houston, Ramsey, and Winona). EAB poses a particularly serious threat to Minnesota because it is home to nearly 1 billion ash trees that occur throughout the state - the second most of any state.
The University of Minnesota’s Landscape Arboretum is the largest and most diverse horticultural site in Minnesota. It features gardens and natural areas representative of Minnesota and the upper-Midwest that can be explored using several miles of trails. Additionally it conducts fruit and plant breeding research to develop cultivars that have particular desired characteristics, such as cold hardiness or disease resistance. The arboretum has a long-term goal of protecting the entire watershed of which it is a part.
Waste streams often contain unutilized resources that if properly extracted or otherwise utilized could be used to provide additional sources of renewable energy or other benefits. Wastewater is one of the primary candidate waste streams because of its nutrient content and researchers have been developing technologies such as microbial fuel cells and algal-based biofuel production in order make use of these nutrients.
The Arboretum, consistent with the priorities of the LSOHC, successfully purchased 78.13 acres in Victoria, Minnesota adjacent to Arboretum property. The purchase will ensure the protection of the deepest lake in Carver County and valuable habitat for future generations.
Moose, one of Minnesota’s most iconic wildlife species, are dying at increasingly higher rates in Minnesota and there is uncertainty as to why. Estimates suggest the population declined 35 percent just between 2012 to 2013, and projections suggest moose could be nearly gone from the state by 2020 if this trend is not halted and, ideally, reversed.
Ecological restorations aim to aid the recovery of native ecosystems that have been degraded or lost. However, very seldom are restorations evaluated past the initial implementation phase to determine whether the efforts achieved their goals and the funds spent were a strategic conservation investment. Monitoring and evaluation of restorations can teach what works and what does not in order to advance restoration practices and increase the likelihood of success for future projects.
Pharmaceuticals, hormones, and other contaminants of emerging concern (CECs) are found in surface waters in Minnesota and nationally. CECs can cause adverse ecological and human health impacts, and occur as complex mixtures in the environment. One of the greatest barriers to addressing the problem of CECs is a lack of understanding of where these compounds come from and which sources dominate in different locations and at different times.
