Title:

Potentially Wet Histosols [Minnesota]

Description:

The Potentially Wet Histosols in Minnesota was created by the MNDNR to display the extent of peatlands across the state using the best available data. For the purposes of this data, peatlands are defined as wet Histosols—the organic soil order that is characteristic of peatlands. The original Peat Inventory of Minnesota (https://gisdata.mn.gov/nl/dataset/geos-peat-inventory) was completed between 1979 and 1982, with additional sites described in 1992, 1994, 1995, 2001 and 2006. The original survey was limited to Koochiching, Aitkin, Beltrami, Lake of the Woods, and Southwestern St. Louis Counties. The Potentially Wet Histosols Map includes this original peatland dataset but provides a complete coverage of histosols across the entire state. The foundation of this dataset is the Gridded National Soil Survey Geographic Database (gNATSGO) Histosols [https://www.nrcs.usda.gov/resources/data-and-reports/gridded-national-soil-survey-geographic-database-gnatsgo], which is a complete coverage of the best available soils information (USDA-NRCS Soil & Plant Science Division). An intersect of the gNATSGO data and the National Wetlands Inventory [https://gisdata.mn.gov/dataset/water-nat-wetlands-inv-2009-2014] was performed to identify the Histosols that are also wetlands. This product has no regulatory implications, nor is it intended for use in detecting change over time (e.g., peatland losses or gains). No new field surveys were conducted in the production of this data, which is a compilation of two primary datasets that incorporate both intensive and extensive field sampling over a span of decades. The data is intended to be used as a tool for understanding the statewide extent of peatlands in Minnesota. The data is not intended for use in detecting change over time (e.g., peatland losses or gains), nor is it intended for use as a stand-alone product at a fine scale. For example, at a site or project level, consulting additional datasets, acquiring new high-resolution imagery or LIDAR, or field visits may all be needed to further verify the presence, condition and characteristics of a specific area identified as a wet histosol on this map. Directive from the Minnesota Legislature: During the Minnesota Legislative Session of 2023, $1.566M from the General Fund was allocated for protecting and restoring carbon storage in state-administered peatlands by reviewing and updating the state's peatland inventory, piloting a restoration project, and piloting trust fund buyouts. The Potentially Wet Histosols of Minnesota dataset was created to fulfill the Legislature’s directive to review and update Minnesota’s peatland inventory.
