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.

The Minnesota County Geologic Atlas program is an ongoing effort begun in 1982 that is being conducted jointly by the University of Minnesota's Minnesota Geological Survey and the Minnesota Department of Natural Resources (DNR). The program collects information on the geology of Minnesota to create maps and reports depicting the characteristics and pollution sensitivity of Minnesota's ground-water resources.
On behalf of the Metropolitan Council, the Minnesota Geological Survey evaluated the vulnerability of glacial aquifers in the Twin Cities metropolitan area. The project improved upon previous vulnerability assessments by incorporating a substantial amount of new aquifer property information and blending methods previously used by the Minnesota Departments of Health and Natural Resources. The result is a consistent vulnerability assessment across the metropolitan area based on the most up-to-date information available.
The Center for Changing Landscapes was directed by the Minnesota State Legislature to create a long-range framework for an integrated statewide parks and trails system that provides information on the natural resource-based recreational opportunities available throughout the state. The detailed framework must include an inventory of existing regionally and statewide significant parks and trails, respond to recreational trends and demographic changes, and identify underserved areas, overused facilities, and gaps in the current parks and trails system (Minn. Gen. Laws 64.8 § 6).
Earthworms are common throughout much of Minnesota, but few realize that they are not native to the state and were in fact introduced from Europe and Asia. Earthworms are invasive in Minnesota and have been shown to have large and potentially irreversible impacts on hardwood forest biodiversity and regeneration. As dispersal by human actions is the primary means of introduction and spread of invasive earthworms, there exists great potential to arrest the current spread of earthworms already present and prevent the introduction of additional species.
Because Minnesota is at the juncture of three distinct types of ecosystems - western prairie, northern coniferous forest, and eastern deciduous forest - the region is particularly sensitive to changes in climate conditions. Understanding how the plants, animals, and waterways of Minnesota might respond to these changes will help the state plan for and manage the potential impacts. The University of Minnesota's Department of Forestry is using this appropriation to analyze past climate conditions in Minnesota and make estimates pertaining to changes expected in the foreseeable future.
This project will provide analysis of geographic patterns, temporal trends of lake clarity and relationships of water clarity to other lake properties, land cover and demographic factors by use of satellite remote sensing. Data for all lakes and years are available in the LakeBrowser, a web-based mapping tool that enables searches and display of results for individual lakes. This project will extend and add to the database, analyze current and new data, and enhance the capability for resource managers to access and use the data.
Native trout require clean, cold water that usually originates from springs, but the springs feeding the 173 designated trout streams in southeastern Minnesota are under increasing pressure from current and expected changes in land use. This joint effort by the University of Minnesota and the Minnesota Department of Natural Resources is working to identify and map the springs and the areas that feed water to these springs and to learn how these waters might be affected by development and water use.
An emerging practice called "precision conservation" aims to maximize conservation benefits by considering the value of lands in terms of the interconnected systems of which they are a part. By compiling and integrating multiple types of data layers and analysis that are available today, conservation professionals can use the best and most precise information available to identify, prioritize, and guide conservation efforts.
This project will develop a surficial geology shapefile (map) for part of the State of Minnesota, by modifying and joining smaller existing, but separate, surficial geology maps. The resulting internally consistent geographic information system (GIS) layer will be used to support the hydrologic parameterization of Minnesota Pollution Control Agency (MPCA) watershed models.
