G#G#: NatureServe Global Conservation Status Rank, Range Rank - A numeric range rank (e.g., G2G3) is used to indicate the rank of uncertainty in the status of a species or community. Ranges cannot skip more than one rank (e.g., GU should be used rather than G1G4). For more information see NatureServe Conservation Status .

G1: NatureServe Global Conservation Status Rank, Critically Imperiled - At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors. For more information see NatureServe Conservation Status .

G2: NatureServe Global Conservation Status Rank, Imperiled - At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors. For more information see NatureServe Conservation Status .

G3: NatureServe Global Conservation Status Rank, 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. For more information see NatureServe Conservation Status .

G4: NatureServe Global Conservation Status Rank, Apparently Secure - Uncommon but not rare; some cause for long-term concern due to declines or other factors. For more information see NatureServe Conservation Status .

G5: NatureServe Global Conservation Status Rank, Secure - Common; widespread, and abundant. For more information see NatureServe Conservation Status .

Global Abundance Comments: Refers to Zoological Elements. Comments on the estimated total population size, including information on how the value (indicated in the Population Size field) was derived, variations, and data for specific portions of the geographic range.

Global Abundance: Code indicating the estimated size of the current naturally-occurring wild population (for species only) Values include: Z = zero individuals, A = 1-50 individuals B = 50-250 individuals, C = 250-1,000 individuals, D = 1,000-2,500 individuals, E = 2,500-10,000 individuals, F = 10,000-100,000 individuals, G = 100,000-1,000,000 individuals, H = >1,000,000 individuals, U = Unknown.

Global Protection: Code that best describes the estimated, inferred, or suspected number of Element Occurrences (EOs) that are appropriately protected and managed for the long-term persistence of the Element within the specified geographic level (i.e., range-wide for global, within-nation for national, or within-state or province for subnational). Values include: A = No occurrences appropriately protected and managed; B = Few (1-3) occurrences appropriately protected and managed; C = Several (4-12) occurrences appropriately protected and managed; D = many (13-40) occurrences appropriately protected and managed; E = very many (>40) occurrences appropriately protected and managed; U = unknown whether any occurrences appropriately protected and managed; (null) = Rank factor not accessed.

Global Range Comments (Species): Description of the species present and historic global range; especially useful for cosmopolitan, circumboreal or wide-ranging species of the western or northern hemisphere for which the distribution also lies outside the coverage of the Natural Heritage Network. Note: For Plants: Additional information may be found under "National Distribution Outside Canada and the United States". For U.S. and Canadian distribution, the information under "Distribution and State/Province Conservation Status Ranks" is more highly edited and complete.

Global Range (Ecological Community or System): The present range of the Ecological Community or Ecological System as defined by climate or known geopolitical boundaries. For more information see Distribution Sources (link).

Global Range (Species): Code that best describes the estimated global range of the species. Values include: Z = Zero occurrences believed to be extant, A = < 100 km2 (less than about 40 square miles) , B = 100-250 km2 (about 40-100 square miles), C = 240-1,000 km2 (about 400-2,000 square miles), D = 1,000-5,000 km2 (about 400-2,000 square miles), E = 5,000-20,000 km2 (about 2,000-8,000 square miles), F = 20,000-200,000 km2 (about 8,000-80,000 square miles), G = 200,000-2,500,000 km2 (about 80,000-1,000,000 square miles), H = > 2,500,000 km2 (greater than 1,000,000 square miles), U = Unknown.

Global Short Term Trend Comments: Comments on short-term trends of a species or ecological community from a range-wide perspective.

Global Short Term Trend: A code that best describes the observed, estimated, inferred, suspected, or projected short-term trend in population size, extent of occurrence, area of occupancy, number of occurrences (EOs), and/or viability/ecological integrity of occurrences (whichever most significantly affects the NatureServe Global Conservation Status). Short-term trends may be recent, current, or projected, and a trend may or may not be known to be continuing. For species, short-term trends are typically considered over a period spanning the past 10 years or 3 generations (whichever is longer up to a maximum of 100 years); for communities or Ecological Systems, over a period spanning the past 10-100 years, depending on characteristics of the type. In considering short-term trends, newly discovered but presumably long existing occurrences are not considered to represent an increasing trend, nor newly discovered individuals in previously little-known occurrences. Also, increases in the number of occurrences due to fragmentation of previously larger occurrences into more but smaller occurrences are not considered to represent an increasing trend, but instead fragmentation of occurrences should be considered as indicative of a decreasing area of occupancy.
A = Severely declining (decline of >70% in population size, range, area occupied, and/or number or condition of occurrences)
B = Very rapidly declining (decline of 50-70%)
C = Rapidly declining (decline of 30-50%)
D = Declining (decline of 10-30%)
E = Stable (unchanged or remaining within ±10% fluctuation)
F = Increasing (increase of >10%)
U = Unknown (short-term trend unknown)
(null) = Rank factor not assessed

Global Status Date: Date the Global Conservation Status Rank, developed by NatureServe and the Natural Heritage Network, was assigned, revised, and/or reaffirmed. For more information see NatureServe Conservation Status.

Global Status Reasons: Summary of factors justifying the Global Conservation Status Rank. For more information see NatureServe Conservation Status.

Global Status: The conservation status rank, developed by NatureServe and the Natural Heritage Network, of a species, Association or Ecological System from a global (i.e., rangewide) perspective, characterizing the relative rarity or imperilment of the element. For more information see NatureServe Conservation Status.

GNA: NatureServe Global Conservation Status Rank, Not Applicable (Species) — A conservation status rank is not applicable because the species is not a suitable target for conservation activities.

Good Viability: Description of what qualifies as an occurrence with good viability, taking into consideration all available knowledge, both historical and current, of the species at a particular location.

Granivore: Taxa that eat seeds or hard fruits (e.g., acorns and various nuts), although not only indirectly (e.g., only as a component of a soft fruit).

Grassland/Herbaceous: Habitat dominated by grasses or forbs; trees and shrubs very widely scattered, if present (includes pastures and hayfields). For more information see Classification of Ecological Communities.

Group Name: If applicable, the name of the group to which the species belongs when group rather than individual criteria are used for the species.

Group: For more information see Classification of Ecological Communities.

GU: NatureServe Global Conservation Status Rank, Unrankable — Currently unrankable due to lack of information or due to substantially conflicting information about status or trends. Whenever possible, the most likely rank is assigned and the question mark qualifier is added (e.g., G2?) to express uncertainty, or a range rank (e.g., G2G3) is used to delineate the limits (range) of uncertainty. For more information see NatureServe Conservation Status.

GX: NatureServe Global Conservation Status Rank, Eliminated (Ecological Communities & Systems) - Eliminated throughout its range, with no restoration potential due to extinction of dominant or characteristic species. For more information see NatureServe Conservation Status.

GX: NatureServe Global Conservation Status Rank, Presumed Extinct (species)- Not located despite intensive searches and virtually no likelihood of rediscovery. For more information see NatureServe Conservation Status .
