The Transit Patterns layer contains all fixed patterns serving the Twin Cities regional metropolitan area. A single route has multiple patterns often characterized by different terminals or branches. One shape and one corresponding record exists for each individual node (time point) segment that compose the pattern. Metro Transit defines a node as reference points that make up a route. These are usually street intersections but can be places. Stops are assigned the node id if they are related to the designated intersection or place. At each node location, actual arrival times are recorded and documented in transit systems. Please note that not all stops are assigned a node id. The line work for the dataset was derived from MRCC Street Centerlines and NCompass Centerlines for Sherburne and Wright County areas. A small number of line segments have been added to completely depict the network traveled by fixed-route transit vehicles.

The Forest Inventory Diameter Distribution table shows the trees per acre by two-inch diameter class for the species present within a stand from the last inventory activity capable of that assessment. Forest diameter distributions are a fundamental data set for assessing stand conditions. They provide actionable intelligence for determining present and possible management as well potential outcomes, such as timber harvest analysis and post treatment conditions. This information is especially critical for stands scheduled for intermediate treatments such as commercial thinning. Data can also be useful for assessing tree species retention within even and uneven-aged managed stands and cover-types.
This dataset contains point representations of the locations of animal feedlot facilities in Minnesota. The data includes contact information, registration/permit information, animal counts, animal units, and information about nearby water bodies.
The Transit Patterns Archive layer contains all fixed patterns serving the Twin Cities regional metropolitan area. A single route has multiple patterns often characterized by different terminals or branches. One shape and one corresponding record exists for each individual transit pattern. The to and from dates represent when that geometry and attribute information was valid. The line work for the dataset was derived from NCompass Street Centerlines pre-November 23, 2019. Line work post-November 23, 2019 is a combination of Road Centerlines (GAC) for the 7-county metro area and NCompass Street Centerlines for Sherburne and Wright county. A small number of line segments have been added to completely depict all patterns traveled by fixed-route transit vehicles.
This dataset includes the main MNDNR Scientific and Natural Areas (SNA) feature class, along with ancillary feature classes such as annotation and parking lots. These feature classes support MNNR's SNA Work Planning application. scientific_and_natural_area_boundaries: A polygon feature class delineated on and digitized from 1:24,000 U.S.G.S. quad maps of Minnesota Scientific and Natural Areas (SNAs). Scientific and natural areas are established to protect and perpetuate in an undisturbed natural state those lands and waters embracing natural features of exceptional scientific and educational value. The SNA Program's goal is to ensure that no single rare feature is lost from any region of the state. This requires protection and management of each feature in sufficient quantity and distribution across the landscape. The Programs' Long Range Plan is to protect at least five locations of plant communities known to occur in each landscape region, and three locations per region of each rare species, plant or animal, and geologic feature. It is estimated that 500 natural areas are needed throughout the state to adequately protect significant features. Because over 40 percent of these rare features occur in prairies, 200 SNAs would be in the prairie area of the state. Of the remainder, approximately 135 are estimated to be needed in the deciduous and 165 in coniferous forest landscape communities in the next 100 years. Protection of multiple sites in each landscape region is a vital means of capturing the genetic diversity and preventing the loss of important species, communities, and features. This strategy observes the wisdom of not putting all our eggs in one basket. In addition to SNA, Itasca and Crow Wing Counties have established county natural areas. Itasca County's natural areas were established in 1966. Sites are set aside as SNAs because of their natural attributes and rare resources, which warrant protection for their inherent values and as places for scientific and educational use. Protection guards against developments such as trails, campgrounds, picnic sites, logging, mineral exploration and development, cultivation, and other uses of land, public or private, that interfere with the preservation of its natural features
The County Well Index (CWI) geodatabase was developed by the Minnesota Geological Survey (MGS) and is maintained in cooperation with the Minnesota Department of Health (MDH). CWI contains basic information for over 511,000 water-wells, and borings drilled in Minnesota. The data is derived from water-well contractors' logs of geologic materials encountered during drilling. Confirmed locations and geologic well records are available for over 325,000 of the wells. Available data also includes casing, screen and pump information. This dataset does not include public water supply wells. This data resource is a regularly updated copy of the database and is maintained by MNIT Services.

The way to access Layers Quickly. Quick Layers is an Add-In for ArcGIS Pro 3 that allows rapid access to the DNR's Geospatial Data Resource Site (GDRS). The GDRS is a data structure that serves core geospatial dataset and applications for not only DNR, but many state agencies, and supports the Minnesota Geospatial Commons. Data added from Quick Layers is pre-symbolized, helping to standardize visualization and map production. Current version: 3.11 To use Quick Layers with the GDRS, there's no need to download QuickLayers from this location. Instead, download a full copy or a custom subset of the public GDRS (including Quick Layers for ArcGIS Pro 3) using GDRS Manager. Quick Layers also allows users to save and share their own pre-symbolized layers, thus increasing efficiency and consistency across the enterprise. Installation: After using GDRS Manager to create a GDRS, including Quick Layers, add the path to the Quick Layers addin to the list of shared folders: 1. Open ArcGIS Pro 2. Project -> Add-In Manager -> Options 3. Click add folder, and enter the location of the Quick Layers Pro app. For example, if your GDRS is mapped to the V drive, the path would be V:\gdrs\apps\pub\us_mn_state_dnr\quick_layers_pro3 4. After you do this, the Quick Layers ribbon will be available. To also add Quick Layers to the Quick Access Toolbar at the top, right click Quick Layers, and select Add to Quick Access Toolbar The link below is only for those who are using Quick Layers without a GDRS. To get the most functionality out of Quick Layers, don't install it separately, but instead download it as part of a GDRS build using GDRS Manager.

The State of Minnesota wetland banking program is authorized by State statutes and associated State rules (Chapter 8420). The program requires that all land being utilized for wetland banking purposes be protected by a State conservation easement, although other land protection mechanisms were used prior to 2000. These protected lands are primarily privately-owned and not accessible to the public without landowner permission. This spatial data layer shows the approximate boundaries of lands protected by State of Minnesota conservation easements and/or other land protection mechanisms associated with the State’s wetland banking program. Information on wetland banking and associated credits can be found at http://bwsr.state.mn.us/wetlands/wetlandbanking/credits.html.

The Metropolitan Council routinely compiles individual land use plans and plan amendments from communities within the seven-county Twin Cities metropolitan area into a single regional data layer. A principal goal of the Regional Planned Land Use dataset is to allow users to view, analyze and display planned land use data for anywhere in the seven county metropolitan area with a consistent land use classification scheme. The Metropolitan Council uses the Regional Planned Land Use (PLU) data to help monitor growth and plan for regional services such as regional parks, transit service, and wastewater collection and treatment. Although the planned land use data is based on the locally adopted land use plans and designations for each community, it represent only data that has been submitted to the Metropolitan Council for review per the Metropolitan Land Planning Act of 1995 (Minn. Stat 473.864, Subd 2 and 473.175, Subd 1). See Data Quality Information (Section 2 of this metadata) for specifics about the Metropolitan Land Planning Act of 1995 under Completeness information. Since there is no official State or Regional land use coding scheme that communities must conform with, the variability of content and codes between communities' land use plans is nearly as vast as the number of communities themselves (187). Differences among communities can range from the implementation of different land use categories to conflicting definitions of similar categories. The PLU dataset attempts to effectively level out the variability among communities by translating communities land use categories and descriptions into a common classification scheme developed and endorsed by MetroGIS (a regional GIS data sharing consortium) participants while retaining each communities' original categories. Although the comparability of land use plans between communities has greatly improved as a result of this translation or "regionalization" of communities' land use codes, it is possible that not all community land use definitions have been precisely translated into the most appropriate regional land use category. In conjunction with other regional information (i.e., land use trend data, households and jobs forecasts), the PLU data can help communities more easily understand regional and sub-regional planning goals and Council staff, working with individual local units of government, can better plan for the future needs and financing of regional services. - Contact individual communities for more information on their locally adopted planned land use categories. - See Data Quality Information (Section 2 of this metadata) for specifics about the development of the regional dataset and its accuracy. - See Entities and Attributes Information (Section 5 of this metadata) for specifics about the regional land use codes and categories.

The MPCA's What's in My Neighborhood contains a wide variety of environmental information about your community. This includes potentially contaminated sites, permits, licenses, registrations, inspections, and closed enforcement activities. Potentially contaminated sites: Since the early 1980s when major federal and state cleanup programs were created, the MPCA has been aggressively searching for and helping to clean up contaminated properties, from very small to large. This website contains a searchable inventory of those properties, as well as sites that have already been cleaned up and those currently being investigated or cleaned up. Environmental permits and registrations: This Web application also contains a searchable inventory of businesses that have applied for and received different types of environmental permits and registrations from the MPCA. Methods for creating site locations have different levels of precision. The most accurate locations use coordinates from GPS (global positioning system). Coordinates are also derived using the site's street address, zip code or public land survey information. Some MPCA sites are not mapped. These are generally activities that are mobile, like ships with ballast water permits.

The “capture zone” is the proposed capture area within the aquifer. When there isn't a surface water contribution, the groundwater capture area is identical to the wellhead protection zone. When a conjunctive delineation is used, the groundwater capture area (GWCA – same as “capture zone’) and the surface water contribution area ( SWCA) are combined to form the wellhead protection area (WHPA).
The Park & Rides and Transit Centers layer contains a comprehensive inventory of park and ride and transit center facilities throughout the Twin Cities Metropolitan area and surrounding counties. Park & Rides are defined as facilities with transit service and parking available, for transit customer and carpool use. Transit Centers are defined as facilities where: two or more routes connect to transfer passengers, buses connect off street (or in clearly designated on-street spaces), there are marked 'gates' for different routes and directions, the location serves a major activity center, and there is a standing facility, or in some cases, a collection of bus shelters. The dataset was geocoded using TLG centerline streets. When specific site details were available, the geography was moved off street lines to actual facility locations using orthophotographic imagery as a base layer. All attempts were made to correctly reflect the real lot locations; however the positional accuracy of this data cannot be guaranteed. The Park-and-Ride Annual Survey lookup table contains information about the capacity and usage at each park-and-ride facility. This table does not include data regarding transit center facilities. Capacity and usage at Park and Pool lots, which are found in a seperate geographic dataset, are also recorded in the Park-and-Ride Annual Survey Table. Attribute information is considered current to the metadata date and will be updated as needed.
The Transit Stops Archive layer contains active transit stops that are part of a transit route itinerary in the Twin Cities seven county metropolitan area. The to and from dates represent when that geometry and attribute information was valid. The earliest version of the Transit Stop itinerary is March 25, 2017. The dataset includes attributes from the primary transit stop database maintained for MetroTransit and for customer information for other transit provider transit services. The locations are mapped referencing road centerlines following the GAC standard along with streets generated internally at Metro Transit.

The Minnesota Groundwater Contamination Atlas GIS data allows users to view groundwater areas of concern for sites in remediation programs. The data does not map areas of risk to the health of the communities. If there are potential health risks associated with a groundwater area of concern, proper remediation treatments or activities are implemented to protect human health. The six different layers in the geodatabase work together to represent what is shown on the site story maps in the Atlas. MPCA hydrogeologists reviewed many reports and data files, then used geographic information systems technology and professional judgment to map these areas. The dashed and solid outlines for these mapped areas represent two different levels of certainty. The solid outline represents area of concern boundaries that are more certain, while the dashed outline represents area of concern boundaries that are less certain. The MN Groundwater Contamination Atlas geodatabase includes the following datasets: Atlas sites Atlas sites no contamination area Atlas wells contamination results summary Atlas cotamination areas of concern Atlas contamination boundaries Atlas potential source areas

The way to access Layers Quickly. Quick Layers is an Add-In for ArcMap 10.6+ that allows rapid access to the DNR's Geospatial Data Resource Site (GDRS). The GDRS is a data structure that serves core geospatial dataset and applications for not only DNR, but many state agencies, and supports the Minnesota Geospatial Commons. Data added from Quick Layers is pre-symbolized, helping to standardize visualization and map production. Current version: 1.164 To use Quick Layers with the GDRS, there's no need to download QuickLayers from this location. Instead, download a full copy or a custom subset of the public GDRS (including Quick Layers) using GDRS Manager. Quick Layers also allows users to save and share their own pre-symbolized layers, thus increasing efficiency and consistency across the enterprise. Installation: After using GDRS Manager to create a GDRS, including Quick Layers, add the path to the Quick Layers addin to the list of shared folders: 1. Open ArcMap 2. Customize -> Add-In Manager… -> Options 3. Click add folder, and enter the location of the Quick Layers app. For example, if your GDRS is mapped to the V drive, the path would be V:\gdrs\apps\pub\us_mn_state_dnr\quick_layers 4. After you do this, the Quick Layers toolbar will be available. To add it, go to Customize -> Toolbars and select DNR Quick Layers 10 The link below is only for those who are using Quick Layers without a GDRS. To get the most functionality out of Quick Layers, don't install it separately, but instead download it as part of a GDRS build using GDRS Manager.

This dataset represents the locations, classifications, and physical characteristics of remediation activities carried out by the Minnesota Pollution Control Agency. The locations represent leak clean up, emergency response, petroleum brownfields, non-petroleum brownfields (Voluntary Investigation and Cleanup), Superfund, RCRA, integrated remediation and site assessment sites. The geodatabase, env_remediation_sites.gdb, contains two related datasets: (1) the remediation_sites point feature class, which has one record for each remediation site, and (2) the spatial_rem_activity table, which contains one record for each MPCA effort to investigate contamination at a site. The two datasets can be related using the ITEM_ID. In most cases, there will be one record in spatial_rem_activity for each record in remediation_sites. However, reopened leak sites may have multiple records in spatial_rem_activity for a single site, and CERCLIS/SEMS sites where the EPA was the lead agency may have zero records in spatial_rem_activity. The spatial_rem_activity table only exists in the file geodatabase format of this dataset.
The Transit Patterns layer contains all fixed patterns serving the Twin Cities regional metropolitan area. A single route has multiple patterns often characterized by different terminals or branches.

Rare natural communities are one of several “Special Considerations” listed in the Wetland Conservation Act rules for consideration under wetland replacement application. The Minnesota Department of Natural Resources (DNR) and Board of Water and Soil Resources (BWSR) have developed guidance with general factors for the DNR to consider in identifying and designating rare natural communities (RNC) under Minnesota’s Wetlands Conservation Act (WCA). Additionally, this guidance is for local units of government (LGUs) to consider when they are determining if a proposed project area includes a rare natural community. This guidance applies solely to the application of the rare natural community rule provision of WCA (see below). BWSR, in consultation with DNR, has adopted rules governing the approval of wetland value replacement plans under WCA. (See Minn. Stat. § 103G.2242 and Minn. R. 8420.0500 - 0544 et. seq.) The WCA rule governing the evaluation of wetland replacement plan applications provides that: “A replacement plan for activities that involve the modification of a rare natural community as determined by the Department of Natural Resource’s natural heritage program must be denied if the local government unit determines that the proposed activities will permanently adversely affect the natural community.” Minn. R. 8420.0515, subp. 3. WCA statutes further provide that: “When making a determination under rules adopted pursuant to this subdivision on whether a rare natural community will be permanently adversely affected, consideration of measures to mitigate any adverse effect on the community must be considered.” Minn. Stat § 103G.2242, subd. 1(d)
This data was created as a result of the Minnesota Pollution Control Agency’s (MPCA) biological stressor identification process (SID).

The MPCA and its partners systematically evaluate waters in each major watershed in Minnesota every 10 years. This process begins with comprehensive lake and stream water quality and biological monitoring. Once completed, the MPCA and its partners assess the monitoring data to determine if the water bodies meet state water quality standards. Protection of “aquatic life” with applicable Class 2 chronic standards means protection of the aquatic community from the direct harmful effects of toxic substances, and protection of human and wildlife consumers of fish or other aquatic organisms. Chloride is a toxic pollutant and has an aquatic life toxicity-based chronic standard. This data set includes a subset of the waterways and waterbodies in Minnesota which have gone through MPCA’s surface water quality assessment process and have been assessed for chloride and information about: the impairment status (in regard to the beneficial use of Class 2 (Aquatic life and recreation)) where the chloride parameter was indicated to be not-supporting, regardless of report cycle (assessment year) the parameter judgement code associated with the most recent (to that WID) assessment (for the chloride parameter) the chloride “Risk Status” (as defined by the Smart Salting Team), where a WID would be identified as “high-risk” due to having results (used in the most recent assessment) which have a concentration of 120 mg/L or greater of chloride. Background The federal Clean Water Act requires states to designate beneficial uses for all waters and develop water quality standards to protect each use. Beneficial uses identify how people, aquatic communities, and wildlife use water. Water quality standards specify the conditions water must meet to protect those specific uses. Measuring lakes and rivers against water quality standards shows which bodies of water need restoration and protection and dictates limits on pollutant discharges from public and private facilities. In Minnesota, the MPCA is charged under both federal and state law with the responsibility of protecting the Minnesota’s water quality. Surface waters (lakes, wetlands, rivers and streams) provide multiple beneficial uses, and so are assigned multiple designated use classes. Chloride is used for assessing the aquatic life beneficial use (Class 2 – Aquatic life and recreation). This use protects ecosystems, habitats, and aquatic biota including fish, insects, mollusks, crustaceans, plans, microscopic organisms, and all other aquatic-dependent organisms and protects recreational uses such as swimming, fishing, hunting, and boating. Minnesota water quality standards protect lakes and streams by defining how much of a pollutant such as bacteria or nutrients can be in the water and allow it to still provide beneficial uses. A surface water is considered to be ‘impaired’ if the extent of its exceedances of applicable water quality standards are more than the levels spelled out in the MPCA Assessment Guidance Manual. This manual is updated every two years in conjunction with the update of the Impaired Waters List. The manual is available on the MPCA’s public website: https://www.pca.state.mn.us/sites/default/files/wq-iw1-04m.pdf If the waters are not meeting their intended beneficial use, they are placed on the impaired waters list (IWL) for detailed tracking of future improvements. Being placed on this list also helps prioritize writing of restoration plans and/or total maximum daily load (TMDL) studies, which aid in mitigation of the pollutants in the waterbodies to bring them once again into a clean water state to meet their intended use. Monitoring strategy Prior to 2008, the monitoring and assessments of waters within state boundaries was minimal. After receiving clean water funds, many more sites were able to be added to the monitoring program. The large increase of data made it impractical to conduct assessments of the entire state’s water quality data annually. Therefore, a watershed approach was created where watersheds were designated a rotational schedule and data from those watersheds are now collected and assessed only once every 10 years. This allows for extensive monitoring to be conducted on waterbodies across the state, and staff to not be overwhelmed with annual assessments. This approach is now called the watershed approach, or the intensive watershed monitoring approach. The MPCA’s primary monitoring activities are organized around Minnesota’s 80 major watersheds. The watershed monitoring approach involves intensive monitoring for conventional pollutants on a subset of major watersheds every year. The MPCA has implemented a schedule for intensively monitoring each major watershed once every 10 years. These monitoring activities result in the identification of waters that are impaired and need restoration, as well as waters that need continued protection to prevent impairment. Assessments are conducted annually in spring, utilizing the previous 10 years of data. The MPCA assessment guidance manual details the procedures and methods MPCA uses to determine if waters are placed on the impaired waters list. Every two years the watershed and statewide assessment results are packaged together into the Impaired Waters List and Integrated Report and submitted to the EPA. Assessment decisions are publicly available via the EPA’s How’s My Waterway (https://mywaterway.epa.gov/), the Minnesota impaired waters list (https://www.pca.state.mn.us/air-water-land-climate/minnesotas-impaired-waters-list), or via MPCA data request. Water quality assessment Surface waters are assessed to determine if they are of a quality needed to support the aquatic community that would be found in the water body under natural conditions. Assessments for aquatic life utilize both water chemistry data and biological data. Technical experts doing the assessments use the assessment database and consider data quality. A key step in the assessment process is to determine if individual parameters meet or exceed their criteria (numeric or narrative standards) or have insufficient data to make that determination. In addition to this comparison against standards, the assessor also makes a determination of the confidence of the parameter assessment, assigning a low, medium, or high-quality rating. For some parameters, the parameter-level evaluation is equivalent to the final use assessment decision (e.g., E. coli bacteria). For other parameters (e.g., biota), the parameter-level evaluations are then used in conjunction with supporting data, including consideration of dataset quality, to make a final determination if a waterbody is meeting its designated use or is considered impaired. Assessors must determine if the water body is not meeting its beneficial use and is considered as having an impaired condition. Any waters determined to have an impaired condition will then be placed on the impaired waters list. However, this is more complex and requires more data reviews than simply analyzing if individual parameter readings are above or below a numerical standard. For example, there needs to be determination on how many exceedances of the standard from individual samples are required in order to label something as impaired. Also, if any of those exceedances can be considered a result of natural weather or habitat conditions, that exceedance may be ruled out as data usable to make an impaired determination since that exceedance is naturally occurring and not anthropogenic. See the MPCA assessment guidance manual to see a detailed break-down how assessors determine if a parameter is exceeding the standard, as well as how to determine if there are enough measurements of that parameter exceeding the standard to count a waterbody as impaired. All assessments are subject to review by a team of professional water quality experts. Review of the data by professionals is an important part of minimizing erroneous impairment determinations and is required whether statistical tests of data uncertainty are used or not. Chloride assessments The MPCA uses data collected over the most recent 10-year period for all the water quality assessments. This period is long enough to provide reasonable assurance that the data have been collected over a range of weather and flow conditions and that all seasons are adequately represented. From a practical standpoint, the ten-year period means there is a better chance of meeting the minimum data requirements for each parameter. A full ten years of data are not required to make an assessment. Protection of “aquatic life” with applicable Class 2 chronic standards means protection of the aquatic community from the direct harmful effects of toxic substances, and protection of human and wildlife consumers of fish or other aquatic organisms. Chloride is a toxic pollutant and has an aquatic life toxicity-based chronic standard. These numeric standards are applied based on a four-day average concentration for the chronic standard (230 mg/L of chloride). Chloride is assessed at a parameter level but if a waterbody exceeds the standard, the parameter-level evaluation can be equivalent to the final use assessments. The necessary number and type of samples can vary considerably from one situation to another and the determination of adequacy for the purpose of assessment will necessarily involve considerable professional judgment. It should benoted that because impairment can result from only one or two exceedances, a designation of meeting the standard generally requires extensive monitoring during times when exceedances are most likely to occur. Chloride assessment of streams When concentrations are judged to be relatively stable over the four-day period in question, single samples can be sufficient. If more than one sample is taken within a four-day period the values are averaged as a mean, and the four-day average is counted as one value in the assessment. This includes multiple samples in four days at one station or multiple stations along an WID. Because the chronic standards are expressed as four-day averages, care must be taken to ensure that the water quality measurements used in assessments provide an adequate representation of pollutant concentrations over the relevant time period. When concentrations are more variable, multiple samples or time-weighted composite samples are can be used in order to calculate a sufficiently accurate average concentration. Flow-weighted composite samples are taken with the purpose of calculating average concentrations by volume rather than by time. As flow-weighted composite samples can be very difficult to interpret in assessment contexts they are not used. Chloride assessment of lakes and wetlands For lakes, depth of sample must be taken into consideration, as concentrations may change with depth (i.e., chloride often increases with depth). Within the four-day period, samples will typically be averaged as follows: those samples collected at depths of 2 meters or less (including both grab samples and 0 - 2 meter integrated samples), those at maximum depth (defined as the deepest two meters of the water column), and the mid-depth values (taken between 2 meters from the surface and the maximum depth). As with flowing waters, this averaging applies to both samples at a single station or samples collected at multiple stations along the WID. Each depth will be compared against the chronic standard. If any four-day average, regardless of depth, exceeds the chronic standard, it counts as a single exceedance for the water body (e.g., the surface average may meet the standard, while the average at 12 meters may exceed the standard – for that four-day period, a single exceedance will be counted).

Natural Area Registry (NAR) Sites layer version supporting SNA Work Planning application. natural_area-registry-sites_boundaries: A polygon database delineated on and digitized from 1:24,000 U.S.G.S. quad maps of Minnesota Natural Area Registry (NARs). (The following text is partially excerpted from: Scientific and Natural Area (SNA) Program Administrative Handbook, Draft EWR Divisional Directive 103, Natural Area Registry, MN DNR, Scientific and Natural Areas Program.) A Natural Area Registry (NAR) Site is a qualifying natural area managed by a government entity (a unit of the federal, state, or local government, (identified as "Landowner", or another Division within DNR, identified as "Primary Administrator") that is covered by a NAR Agreement by which the site becomes part of the Natural Area Registry. Sites in this program are managed by various public agencies with management recommendations provided by the Scientific and Natural Areas program and Regional Ecologist. NARs are established through the use of Natural Area Registry (NAR) Agreements which are non-binding written agreements between the Division of Ecological and Water Resources (EWR) and another governmental entity. The NAR Agreement identifies the site, explains its significance, describes a proposed management direction, and states that before any management contrary to that direction may occur, the parties who signed the agreement will discuss that proposed management activity. Note: formerly a "Memorandum of Understanding" (MOU) was the vehicle used as the NAR agreement and in many documents, preceding development of this Directive, these terms were used interchangeably. The Minnesota Department of Natural Resources (DNR) Natural Areas Registry is intended to recognize tracts of public land that contain natural features of statewide ecological significance and possess exceptional scientific or educational value. NARs recognize the agencies and individuals that manage these lands to protect and perpetuate the features of interest. Minnesota Statute 86A.05, Subd. 5 states that the Minnesota Scientific and Natural Areas Program was "established to protect and perpetuate in an undisturbed natural state those natural features which possess exceptional scientific or educational value." This Registry acknowledges that many of Minnesota's finest natural areas occur on other public lands that are not designated as SNAs. Through adoption of ecologically-based management principles and voluntary coordination between the land manager and the SNA Program, Registry sites protect a broader cross section of the state's natural diversity. Tracts of public land that contain viable examples of natural features of statewide ecological significance may be identified as NAR candidate sites. Qualifying sites are selected based upon Landowner/Primary Administrator interest and on the site's ecological quality. Priority is given to sites that are within MCBS-mapped outstanding and high biodiversity significance sites, are predominantly MCBS-mapped native plant communities, and contain habitat for rare species and Species of Greatest Conservation Need (SGCN), or geological features of statewide significance. Sites nominated for potential NAR registration are reviewed using information compiled in an Ecological Evaluation (EE) or brief written summary of natural features, to determine if the site qualifies for NAR and if protection through NAR is acceptable to all parties. The Natural Areas Registry was established in the early 1980s within the DNR Section of Wildlife's Natural Heritage Program, in order to recognize public lands which contain natural features of special interest and to facilitate their protection and perpetuation. The Registry was modeled after The Nature Conservancy's Private Lands Register, which is no longer in existence. A number of other states (and international governmental entities) have a Natural Area Registry or Natural Area Register, which may supplement or be in lieu of a system of designated Natural Areas. In 1986, the administration of the Registry, with 26 NAR sites, was transferred from the Natural Heritage Program to the SNA Program. Both programs were within the DNR Section of Wildlife at the time. The first NAR site established was the Soudan Iron Formation at Tower Soudan State Park, February 1982. From the inception of the Natural Area Registry in 1982 through April 2014, there are 41 sites in the Registry. Note: through 2011 the NAR has been referred to as both Natural Area Register and Natural Area Registry, with adoption of this directive, the name Natural Area Registry will consistency be used in all future NAR Agreements, and if/when updated, previous agreements will be changed to use this naming convention. This Representation SNA boundaries is based on the NAR_BASE_DATA feature class in the DNR's core GIS Library. It includes only DEDICATED features, which are dissolved on the following attributes: SITENAME, SITE_ID, BREMCODE. The coverage should be reasonably accurate although the boundaries probably will not line up with other public land survey information. Some of the boundaries for NAR sites have been created by DNR and other partner staff, and are often sub units within a larger unit. Since the NAR boundaries have no legal standing, the accuracy of boundaries vary from site to site, but are typically reasonable approximations of the NAR site boundary.
