| s_rank_cat | enumerated | Subnational (State) Conservation Status Rank - Categories: This field shows the subnational (state) conservation status rank (s-rank) as one of three categories: 1) S1-S3, 2) Possible S1-S3, and 3) not S1-S3. | |
| S1-S3 | The polygon is S1, S2 or S3. | |
| Possible S1-S3 | The polygon (or parts of it) may be S1, S2 or S3 if it was classified to a more precise level of the classification system (i.e. type or subtype level). | |
| Not S1-S3 | The polygon is not S1, S2 or S3. | |
| s_rank_highest_risk | enumerated | Subnational (State) Conservation Status Ranks - Highest Risk: This field contains the highest risk s-rank(s) associated with a classification. This will be equivalent to the s_rank_code field if the classification is to the subtype level (e.g. WMs83a1) or if at the type level (e.g. WMs83a1) when there is no ‘or’ in the s_rank_code risk value. If the classification is to class (e.g. WMs83) or to type when there is an ‘or’ in the s_rank_code, the value will be the s-rank representing the most vulnerability (e.g. s_rank_code of ‘S2 or S3’ will receive ‘S2’). Class level s-rank highest risk values will contain parentheses to show that the value is based on the highest risk of all the s-ranks values of its types and subtypes. Another use of the parentheses is for when the classification is a Complex code in which case the value in parentheses represents the highest risk s-rank for all the classifications found in that complex. (See S and G ranks link in the overview section above for a list of all s-rank values by native plant community and complex classification.) | NatureServe Conservation Status Rank: Interpreting G-ranks and S-ranks for Native Plant Communities (Version 1.3, April 1, 2009) |

| g_rank_detailed | - | NatureServe Global Conservation Status Rank - Detailed: This field shows all G-ranks associated with this DNR classification unit. G-ranks for DNR NPC classification units are crosswalked from G-ranks assigned to the National Vegetation Classification (NVC) by NatureServe. (For details on the meanings of the ranks, see https://www.natureserve.org/conservation-tools/conservation-status-assessment.)
NVC classification units most directly crosswalk to the DNR classification at the DNR Type (for example WMs83a) and/or Subtype (for example WMs83a1) levels. G-ranks for DNR classification units higher than Type (e.g. Class) are derived from the Types and Subtypes within the Class or System. A G-rank bracketed by parentheses indicates a G-rank derived from lower-level DNR classification units and will include all values listed for Types and Subtype. Whereas a G-rank without parentheses indicates a direct G-rank from the NVC for that DNR NPC classification unit. (For more information on the classification hierarchy, see https://www.dnr.state.mn.us/npc/classification.html.)
If an NPC classification includes an 'or' in its G-rank value, that DNR NPC classification crosswalked to more than one NVC classification. (For details on the particular g-rank crosswalk for a DNR NPC classification, most helpful in the cases of an 'or' in the g-rank, see the 'MN Crosswalk to NVC Classifications' link in the 'Overview' section above.)
For complex codes (ending in "_CX"), the g-ranks in parentheses include all the g-ranks for the constituent NPC communities that may be included in that complex. More details about complexes and their constituent NPC classifications and g-ranks are found in the document "NPC_Complexes". (See the link in the 'Overview' section above.)
The value of 'Not available at this level' means the DNR NPC classification is a classification level higher than Class, Type or Subtype. Giving a detailed listing of g-rank possibilities here would not be meaningful because in most cases the potential list would be too long. | NatureServe Conservation Status Rank: Interpreting G-ranks and S-ranks for Native Plant Communities (Version 1.3, April 1, 2009) |
| g_rank_cat | enumerated | NatureServe Global Conservation Status Rank - Categories: This field shows the global conservation status rank (G-rank) as one of three categories: 1) G1 or G2, 2) Possible G1 or G2, and 3) not G1-G2.
The main purpose is to allow quick identification of the most at risk polygons.
When the category is ‘Possible G1 or G2’, the polygons are classified to the DNR Class level or higher or to a Complex code; these polygons may contain high g-ranks (G1 or G2) which could be determined if polygons were classified to DNR Type or Subtype. (See classification hierarchy at https://www.dnr.state.mn.us/npc/classification.html.) | |
| G1 or G2 | The polygon is G1 or G2. | |
| Possible G1 or G2 | The polygon (or parts of it) may be G1 or G2 if it was classified to a more precise level of the classification system (i.e. type or subtype level). | |
| Not G1 or G2 | The polygon is not G1 or G2. | |
| g_rank_highest_risk_rounded | enumerated | NatureServe Global Conservation Status Rank - Highest Risk, Rounded: This field shows the rounded highest risk G-rank(s) associated with a classification.
G-ranks were determined by NatureServe for their National Vegetation Classification (NVC) and applied to the Minnesota Native Plant Community classification (NPC) via a crosswalk table.
This basis of this field are values from the field 'g_rank_detailed' and uses the highest risk if there is a list of values (e.g. G2 is higher risk than G4).
It rounds that value to G1, G2, G3, G4, or G5 (the basic ranks) in order to simplify the larger list of variants and qualifiers seen in 'g_rank_detailed'. (For ranking details see, https://www.natureserve.org/conservation-tools/conservation-status-assessment.)
For classifications at the level of Type (for example WMs83a) or Subtype (for example WMs83a1), the values will appear without parentheses. If there are parentheses around the G-rank(s), the classification is at a higher level of the classification hierarchy (for example the Class level WMs83) and the value is the rounded highest risk of all the Type and Subtype classifications that are subordinate to it in the classification system. So if WMs83 consists of WMs83a which is G4, WMs83a1 which is G4, WMs83a2 which is G3, and WMs83a3 which is G4, the polygon's rounded highest risk will be '(G3)', representing the highest risk of the subordinate classifications. (For more information on the classification heirarchy, see https://www.dnr.state.mn.us/npc/classification.html.)
Another use of the parentheses is for when the classification is a Complex code and the values in parentheses represent the rounded highest risk g-ranks for all the classifications found in that complex. For Complex codes (which end in '_CX'), more information about their constituent NPC classifications and g-ranks are found at 'NPC_Complexes.pdf' (find link in the Overview section above). | NatureServe Conservation Status Rank: Interpreting G-ranks and S-ranks for Native Plant Communities (Version 1.3, April 1, 2009) |
| G1 | Critically Imperiled—At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors. | NatureServe (https://www.natureserve.org/conservation-tools/conservation-status-assessment) |
| G2 | Imperiled—At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors. | NatureServe NatureServe (https://www.natureserve.org/conservation-tools/conservation-status-assessment) |
| G3 | Vulnerable—At moderate risk of extinction due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors. | NatureServe (https://www.natureserve.org/conservation-tools/conservation-status-assessment) |
| G4 | Apparently Secure—Uncommon but not rare; some cause for long-term concern due to declines or other factors. | NatureServe (https://www.natureserve.org/conservation-tools/conservation-status-assessment) |
| G5 | Secure—Common; widespread and abundant. | NatureServe (https://www.natureserve.org/conservation-tools/conservation-status-assessment) |
| GNR | Unranked—Global rank not yet assessed. | NatureServe (https://www.natureserve.org/conservation-tools/conservation-status-assessment) |
| (G1) | G1 is the rounded highest risk g-rank of all the g-ranks of the subordinate type and subtype classifications within this classification. | |
| (G2) | G2 is the rounded highest risk g-rank of all the g-ranks of the subordinate type and subtype classifications within this classification. | |
| (G3) | G3 is the rounded highest risk g-rank of all the g-ranks of the subordinate type and subtype classifications within this classification. | |
| (G4) | G4 is the rounded highest risk g-rank of all the g-ranks of the subordinate type and subtype classifications within this classification. | |
| (G5) | G5 is the rounded highest risk g-rank of all the g-ranks of the subordinate type and subtype classifications within this classification. | |
| (GNR) | GNR is the rounded highest risk g-rank of all the g-ranks of the subordinate type and subtype classifications within this classification. | |
| Not available at this level | The NPC classification is not at the classification level of class, type, or subtype (see classification hierarchy section at https://www.dnr.state.mn.us/npc/classification.html). Giving a detailed listing of g-rank possibilities would not be meaningful as in most cases the list would be long due to the general nature of the classification. | |
| biodiversity_signif_rank | enumerated | Ecological and Water Resources Division rank of overall site | Guidelines for Assigning Statewide Biodiversity Significance Ranks to Minnesota County Biological Survey Sites (http://files.dnr.state.mn.us/eco/mcbs/biodiversity_significance_ranking.pdf) |
| Outstanding | Sites 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. | |
| High | Sites containing very good quality occurrences of the rarest species, high-quality examples of rare NPCs, and/or important functional landscapes. | |
| Moderate | Sites containing occurrences of rare species and/or moderately disturbed NPCs, and/or landscapes that have a strong potential for recovery. | |
| Below | Sites 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_method | enumerated | Method used to acquire data | |
| G | Ground 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. | |
| E | Peripheral 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. | |
| A | Aerial Survey: Surveyor gained information about the community by aircraft, helicopter, etc. | |
| O | Other: 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. | |
| P | Photo 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). | |
