Section 1: Overview

Originator:Minnesota Department of Natural Resources (DNR)

Title: MNDNR Native Prairies

Abstract: Native prairie polygons are a subset of a larger database of DNR Native Plant Communities and are the result of that classification system and protocol.

As a subset of the DNR Native Plant Communities dataset, this dataset contains selected native plant community classifications (prairies) that result from the Minnesota Biological Survey (MBS), State Park land cover data, Forestry native plant community data, and Wildlife Management Areas land cover data. It includes polygons representing the highest quality native prairie communities remaining in surveyed areas. These native prairie communities are important areas for conservation.

Native plant communities (sometimes also referred to as "natural communities") are groups of native plants that interact with each other and their surrounding environment in ways not greatly altered by modern human activity or by introduced plant or animal species. These groups of native species form recognizable units, such as an oak forest, a prairie, or a marsh, that tend to repeat across the landscape and over time.

Native plant communities are generally classified and described by considering vegetation, hydrology, land forms, soils, and natural disturbance regimes. The native plant community types and subtypes in this data layer are classified primarily by vegetation and major habitat features.

Areas that are not mapped as native plant community polygons primarily represent: 1) land where modern human activities such as farming, overgrazing, wetland drainage, recent logging and residential and commercial development have destroyed or greatly altered the natural vegetation; and 2) native plant community polygons that were below minimal size criteria.

Note: some areas that are not mapped are important for conservation. They may include habitat for native plants and animals, corridors for animal movement, buffers surrounding high quality natural areas and open space, and target areas for restoration.

Purpose: To foster better understanding and protection of Minnesota's native prairies.

Section 2: Data Quality

Attribute Accuracy: Attributes go through a rigorous certification process

Logical Consistency: Data are topologically structured and verified.

Completeness: Data are complete for each county with MBS data and all State Parks. State Forests and WMA are partially complete.

Horizontal Positional Accuracy: No quantitative studies of horizontal positional accuracy exist for the data. Positional accuracy can be reasonably estimated based on the characteristics of source materials and processing techniques to be 45-60 feet (14-18 meters) from correct position.

Vertical Positional Accuracy: Not Applicable

Lineage: This data is extracted from the Minnesota DNR's Native Plant Community database sytem. Candidate features and attributes go through extensive verification and quality control before being certified for publishing through the MNDNR's Geospatial Data Resource site and the Minnesota Geospatial Commons.

OutstandingSites containing the best occurrences of the rarest species, the most outstanding examples of the rarest native plant communities, and/or the largest, most intact functional landscapes present.
HighSites containing very good quality occurrences of the rarest species, high-quality examples of rare NPCs, and/or important functional landscapes.
ModerateSites containing occurrences of rare species and/or moderately disturbed NPCs, and/or landscapes that have a strong potential for recovery.
BelowSites below minimum biodiversity threshold for statewide significance. These sites lack occurrences of rare species or natural features or do not meet MCBS standards for Outstanding, High, or Moderate rank. These sites may include areas of conservation value at the local level, such as habitat for native plants and animals, corridors for animal movements, buffers surrounding higher quality natural areas, or areas with high potential for restoration of native habitat.

collection_methodenumeratedMethod used to acquire data
GGround Survey: Surveyor gained information about the community through ground survey; done for the purpose of NPC evaluation. This includes but is not limited to: comprehensive walk-through supported by waypoints & field notes, releves, or forestry transect worksheets. This is performed by you personally or performed by others and given to you to use.
EPeripheral Edge: Survey Surveyor gained information about the community by viewing from edge (drive-by, canoe, etc.) or cursory walk through. Again, this action is performed by you personally or performed by others and the data is given to you to use.
AAerial Survey: Surveyor gained information about the community by aircraft, helicopter, etc.
OOther: Surveyor used some type of physical document usually in the form of a report or publication that lends some supporting information about a map polygon. These are a contrast to the standard derived spatial layers typically consulted in a GIS. Examples would be a forest service report that included some reference text to help describe the NPC delineation/classification process, but the report was carried out for a purpose other than NPC evaluation.
PPhoto Interpretation: Using Derived Data layers the surveyor gained information about the community from data sources that do not represent a physical visit to the polygon for the purpose of NPC evaluation. This data is typically remotely sensed data (Air Photos, GAP, LiDAR, DEMs), extrapolated data (soil surveys, NWI) or other natural resource inventories (FIM, CSA).
