Abstract Beginning in 1975 and continuing today, there has been a renewed interest in peat for horticulture and for fuel. This interest prompted the development of the Peat Inventory Project in 1976 to outline the dimensions of major peat areas in northern Minnesota and to determine the quantity, quality, type, and depth of the peat deposits.

The DNR planned to utilize the inventory data for three purposes: to assess the horticultural potential of the state's resources, to assess the energy potential of the state's peatland, and to support a comprehensive state policy on peatland management. With the U.S. Department of Energy funding beginning in 1979, the DNR accelerated and expanded peat investigations in Minnesota.

The first Peat Inventory report and accompanying map was published in 1979, the last report and map was published in 1982 (refer to the Associated Data Sets section for a list of these reports, listed under part 1). Recently, the reports were scanned and are available as pdf files; the accompanying published maps were scanned and rectified for use with GIS software.

Additional peat inventory data has been collected and is available for use in a Microsoft Access database, but any final reports or maps have not been captured digitally for inclusion with this information (refer to the Associated Data Sets section under part 2).

Title Peat Inventory Published Maps and Reports - Minnesota
Abstract Beginning in 1975 and continuing today, there has been a renewed interest in peat for horticulture and for fuel. This interest prompted the development of the Peat Inventory Project in 1976 to outline the dimensions of major peat areas in northern Minnesota and to determine the quantity, quality, type, and depth of the peat deposits.

The DNR planned to utilize the inventory data for three purposes: to assess the horticultural potential of the state's resources, to assess the energy potential of the state's peatland, and to support a comprehensive state policy on peatland management. With the U.S. Department of Energy funding beginning in 1979, the DNR accelerated and expanded peat investigations in Minnesota.

The first Peat Inventory report and accompanying map was published in 1979, the last report and map was published in 1982 (refer to the Associated Data Sets section for a list of these reports, listed under part 1). Recently, the reports were scanned and are available as pdf files; the accompanying published maps were scanned and rectified for use with GIS software.

Additional peat inventory data has been collected and is available for use in a Microsoft Access database, but any final reports or maps have not been captured digitally for inclusion with this information (refer to the Associated Data Sets section under part 2).
Purpose The Peat Inventory Project was created in 1976 as a sub-program of the Minnesota Peat Program. Its purpose was to assess the horticultural and energy potential of the state's peat resource and to support a comprehensive state policy on peatland management. Beginning in 1979 and continuing for several years, the MN DNR received funding from the U.S. Department of Energy, which accelerated and expanded fuel peat investigations in Minnesota.

In the early years, during which time these maps and reports were produced, the DNR used a reconnaissance-level peatland survey. The surveys were intended to be broad in scope and designed to collect information for general land-use planning and to locate areas with potential for development. Data were collected at random locations and sometimes along traverses in the often remote and almost inaccessible northern peatlands. At observation sites, crews collected notes on the peatland vegetation, determined the peat type throughout the profile, measured the peat depth, and collected samples for analysis.

In later years, the DNR used a detailed-level peatland survey. Detailed surveys, by definition, are more focused, site-specific investigations, designed to specify development potential. The detailed surveys were undertaken following the ranking of survey areas according to their potential. Staff investigated the exact quality and quantity of the peat, as well as site characteristics that affect the cost of development. The survey results included written reports (not available as digital files) that have isopact maps of the deposits, descriptions of the peat material, cross sections that illustrate the botanical components and humidification of the deposits, volume and tonnage estimates, and surface elevation maps. The detailed surveys were conducted using grid survey techniques, in which resource data are collected systematically at points on a grid. If any of the detailed peatland surveys were done in areas where the maps were published, the maps were not updated to reflect these surveys.

The data for both types of surveys can be found in the dataset entitled Peat Inventory Data - Minnesota (refer to the Associated Data Sets section, part 2), which includes a Microsoft Access database and a shapefile of inventory site locations.

Attribute Accuracy
Logical Consistency
Completeness
Horizontal Positional Accuracy These scanned maps should be used only as a secondary source of information and are probably best suited for use at 1:100000, or smaller scale, for two reasons:
1) The peat inventory and the resulting published maps for these counties were considered to be reconnaissance-level surveys. The peat/mineral soil boundaries were originally delineated through air photo interpretation onto 1:63360 (1 inch to 1 mile) MN DOT county highway maps. For publication, these maps were photographically reduced to 1:126720 (1/2 inch to 1 mile).
2) In 2007, these maps were scanned and rectified to section corners contained in a data layer referred to as PLS40 (also referred to as Control Point Generated Public Land Survey). The RMS factor when rectifying was generally 60-80 meters, with some locations having a greater RMS factor.
Lineage Surficial geology mapping, done by Morris Eng, served to delineate the mineral areas from the peat areas. Eng used air photo interpretation to delimit various geomorphic features and peatland patterns and landforms. USGS 7.5 minute topographic maps provided locational reference during map compilation. Following preliminary mapping, selected areas were field checked. The mapping units were then drawn on a MN DOT county highway map for the respective area at a scale of 1:63360 (1 inch to 1 mile) and then photographically reduced to 1:126720 (1/2 inch to 1 mile).

Peat mapping units were established to differentiate the depth, degree of decomposition, and botanical origin of the peat. The preliminary field data were plotted on USGS topographic maps. These data, in conjunction with air photo interpretation, were used to draw depth contours. Areas capped by fibric sphagnum moss (i.e., raised bogs), were also delineated by depth. The quadrangles were then reduced to 1:126720 and the peat information was transferred to the map on which the surficial geology units (or at least the mineral soil/peat boundaries) were delineated. Due to the effects of generalization during map compilation and production, mapping units may contain minor inclusions of other mapping units.

The final maps were created by manual overlay techniques that included registered layers that were created by pen and ink, scribing/peelcoat, photographic positive on mylar of the MN DOT county highway map, and so on. The overlays were combined into four negatives, proofed, and then four printing plates were created for the press run.

These scanned maps should be used only as a secondary source of information and are probably best suited for use at 1:100000, or smaller scale, for two reasons:
1) The peat inventory and the resulting published maps for these counties were considered to be reconnaissance-level surveys. The peat/mineral soil boundaries were originally delineated through air photo interpretation onto 1:63360 (1 inch to 1 mile) MN DOT county highway maps.

Section 5 Entity and Attribute Information Top of full metadata Top of page
Entity and Attribute Overview The map legend is included on each of the scanned map images.
On the peat maps, there is basic information about mineral versus peat areas, peat depths, depths of the sphagnum moss caps (i.e., raised bogs), and a differentiation of the degree of decomposition. The USDA Soil Conservation Service nomenclature is correlated with the von Post scale of decomposition in the following manner:
Fibric = H1 to H3
Hemic = H4 to H6
Sapric = H7 to H10

On the surficial geology maps (SW St. Louis includes both surficial geology and peat), the map legends differentiate peat versus other surficial geology units and peatland landforms.
