Section 1 Overview
Originator Minnesota Department of Natural Resources (DNR)
Title Calcareous Fens - Source Feature Points
Abstract Pursuant to the provisions of Minnesota Statutes, section 103G.223, this database contains points that represent calcareous fens as defined in Minnesota Rules, part 8420.0935, subpart 2. These calcareous fens have been identified by the commissioner by written order published in the State Register on June 2, 2008 (32 SR 2148-2154), August 31, 2009 (34 SR 278) and December 7, 2009 (34 SR 823-824). The current list of fens (DNR List of Known Calcareous Fens) is posted on the DNR's web site at: files.dnr.state.mn.us/eco/wetlands/calcareous_fen_list.pdf

This data set is a GIS point shapefile derived from the Natural Heritage "Biotics" Database. Data in the Biotics Database are maintained according to established Natural Heritage Methodology developed by NatureServe and The Nature Conservancy. The core of the Biotics Database is made up of Element Occurrence (EO) records of rare plant and animal species, animal aggregations, native plant communities, and geologic features. An Element is a unit of biological diversity, such as a species, subspecies, or a native plant community. An EO is an area of land and/or water in which an Element is, or was, present, and which has practical conservation value for the Element (e.g. species or community) as evidenced by potential continued (or historical) presence and/or regular recurrence at a given location. Source Features are the mapped representation of observations of rare features. Source Features are then evaluated using biological standards, and grouped into EOs as appropriate.

This data set contains a point for each Calcareous Fen (DNR List of Known Calcareous Fens) Source Feature in the Biotics database, and selected attributes from the Source Feature record and it’s linked Element Occurrence (EO) record.
Purpose It is anticipated that this data set will primarily be used as a screening tool for clients that need to comply with the Wetland Conservation Act.

Use Constraints In order to protect the DNR's copyright interest in these data, any product derived from this GIS data set should include an appropriate copyright notice. The user should also acknowledge the DNR's Division of Ecological Resources as the source of the information. This can be accomplished by printing the following statement on any product containing these data. "Calcareous Fen locations were provided by the Division of Ecological Resources, Minnesota Department of Natural Resources (DNR), and were current as of 05/2017."

Section 2 Data Quality
Attribute Accuracy All data go through a quality control process after entry.
Logical Consistency Not Applicable
Completeness Subject to future revisions as the official DNR List of Known Calcareous Fens is subject to revisions. This shapefile will be updated when the official list is updated. This data set contains only fens reported to the Division of Ecological Resources. Other fens may occur in Minnesota for which we have no observation record.
Horizontal Positional Accuracy Horizontal positional accuracy varies greatly due to the varying level of precision in data submitted for entry. Accuracy is reflected in the LU_DIST and LUDISTUNIT fields.
Vertical Positional Accuracy Not Applicable
Lineage Tabular data are entered into an ORACLE database. Output views are generated by Structured Query Language (SQL) scripts.

Spatial locations are recorded in an ORACLE spatial database. An ORACLE view is generated and joined to produce the resulting layer.

Overview This data set is a GIS point shapefile derived from the Natural Heritage "Biotics" Database. Data in the Biotics Database are maintained according to established Natural Heritage Methodology developed by NatureServe and The Nature Conservancy. The core of the Biotics Database is made up of Element Occurrence (EO) records of rare plant and animal species, animal aggregations, native plant communities, and geologic features. An Element is a unit of biological diversity, such as a species, subspecies, or a native plant community. An EO is an area of land and/or water in which an Element is, or was, present, and which has practical conservation value for the Element (e.g. species or community) as evidenced by potential continued (or historical) presence and/or regular recurrence at a given location. Source Features are the mapped representation of observations of rare features. Source Features are then evaluated using biological standards, and grouped into EOs as appropriate.

This data set contains a point for each calcareous fen Source Feature in the Biotics database, and selected attributes from the Source Feature Oracle record and it's linked Element Occurrence (EO) record. Some of the fens listed in the DNR List of Known Calcareous Fens are represented as multiple points.

The fields CNTY_NAME and TRS contain the location information for the fen point. The actual fen boundary may be located within more than one section or county. For a complete list of sections for each fen, please refer to the current list of fens posted on the DNR's web site at:
files.dnr.state.mn.us/eco/wetlands/calcareous_fen_list.pdf

The Minnesota County Biological Survey has also delineated boundaries for some of the fens. These boundaries are included in a GIS dataset ('MCBS Native Plant Communities') that can be downloaded from the Minnesota Geospatial Commons.

The fields LU_DIST and LUDISTUNIT contain information on the locational uncertainty of the data.

Source features can have "repeat observations" - that is, observations from more than one date. Therefore several fields (most notably the Observation Date fields) may have multiple entries.

The recorded (i.e., mapped) location of an observation may vary from its true location due to many factors, including the level of expertise of the data collector, differences in survey techniques and equipment used, and the amount and type of information obtained. This inaccuracy is characterized as locational uncertainty.

The requirement to publish the DNR's official list of calcareous fens in the State Register became law in 2004 and an updated list was first published in March, 2005, with periodic updates since. The official records for the DNR's list of calcareous fens are kept by the Wetland Program Coordinator, Ecological and Water Resources Division (as of April, 2017).
