Massachusetts Species of Greatest Conservation Need (SGCN)

Five hundred and seventy species were determined to be Species of Greatest Conservation Need (SGCN) in Massachusetts as presented in the 2015 update to the Massachusetts State Wildlife Action Plan (SWAP).

The tables below list all of the SGCN in Massachusetts, with their global rank, federal status, regional SGCN status (RSGCN, for vertebrates, freshwater mussels, tiger beetles, and federally listed invertebrates only; see Section D of State Wildlife Action Plan Chapter 3, for an explanation), MESA status, other concerns and comments (including level of RSGCN concern and responsibility; see Section D of State Wildlife Action Plan Chapter 3), and SWAP Habitats. For an explanation of the SWAP Habitats, see State Wildlife Action Plan Chapter 4. Details on each of these species, including a short description, their distribution and abundance in the state, habitat description, threats, and references, can be found in the online fact sheets (linked from the common names). Up to date state status can be found on the species fact sheets or by viewing the List of Endangered, Threatened, and Special Concern species.

Abbreviations

• Global Rank:  These are the conservation status ranks as defined by NatureServe (NatureServe 2014).  Ranks considered globally rare (G1 through G3G4) are in bold in the table above.

 

Basic Ranks

Rank	Definition
GX	Presumed Extinct (species)—Not located despite intensive searches and virtually no likelihood of rediscovery. Eliminated (ecological communities)—Eliminated throughout its range, with no restoration potential due to extinction of dominant or characteristic species.
GH	Possibly Extinct (species)—Missing; known from only historical occurrences but still some hope of rediscovery. Presumed Eliminated—(Historic, ecological communities) - Presumed eliminated throughout its range, with no or virtually no likelihood that it will be rediscovered, but with the potential for restoration, for example, American Chestnut (Forest).
G1	Critically Imperiled—At very high risk of extinction due to extreme rarity (often 5 or fewer populations), very steep declines, or other factors.
G2	Imperiled—At high risk of extinction due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors.
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.
G4	Apparently Secure—Uncommon but not rare; some cause for long-term concern due to declines or other factors.
G5	Secure—Common; widespread and abundant.

 

Variant Ranks

Rank	Definition
G#G#	Range Rank—A numeric range rank (e.g., G2G3) is used to indicate the range 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).
GU	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.
GNR	Unranked—Global rank not yet assessed.
GNA	Not Applicable—A conservation status rank is not applicable because the species is not a suitable target for conservation activities.

 

Rank Qualifiers

Rank	Definition
?	Inexact Numeric Rank—Denotes inexact numeric rank (e.g., G2?)
Q	Questionable taxonomy—Taxonomic distinctiveness of this entity at the current level is questionable; resolution of this uncertainty may result in change from a species to a subspecies or hybrid, or the inclusion of this taxon in another taxon, with the resulting taxon having a lower-priority conservation priority.
C	Captive or Cultivated Only—At present extant only in captivity or cultivation, or as a reintroduced population not yet established.

 

Infraspecific Taxon Conservation Status Ranks
Infraspecific taxa refer to subspecies, varieties and other designations below the level of the species. Infraspecific taxon status ranks (T-ranks) apply to plants and animal species only; these T-ranks do not apply to ecological communities.

Rank

Definition

T#

Infraspecific Taxon (trinomial)—The status of infraspecific taxa (subspecies or varieties) are indicated by a "T-rank" following the species' global rank. Rules for assigning T-ranks follow the same principles outlined above for global conservation status ranks. For example, the global rank of a critically imperiled subspecies of an otherwise widespread and common species would be G5T1. A T-rank cannot imply the subspecies or variety is more abundant than the species as a whole-for example, a G1T2 cannot occur. A vertebrate animal population, such as those listed as distinct population segments under the U.S. Endangered Species Act, may be considered an infraspecific taxon and assigned a T-rank; in such cases a Q is used after the T-rank to denote the taxon's informal taxonomic status.

 

• Federal List:  Legal status under the federal Endangered Species Act of 1973.

LE: endangered. A species "in danger of extinction throughout all or a significant portion of its range."
LT: threatened. A species "likely to become endangered within the foreseeable future throughout all or a significant portion of its range."

• RSGCN: Species on the regional list of Species of Greatest Conservation Need (Terwilliger Consulting, Inc., and the Northeast Fish and Wildlife Diversity Technical Committee, 2013). 

• NEPCoP: Status in the 2013 New England Flora Conservanda (Brumback and Gerke 2013).  The numbers refer to the divisions designated in the Flora Conservanda.

Division 1: Globally rare taxa occurring in New England.
Division 2: Regionally rare taxa.  Generally, these taxa have 20 or fewer current occurrences in the region.  Some Division 2 taxa may have more than 20 occurrences, but they are included because they are “vulnerable to extirpation due to other important factors (population size and trends, area of occupancy, overall viability, geographic distribution, habitat rarity and integrity, and/or degree of protection).”  Taxa in this last category are labeled 2(a).
Division 3: Locally rare taxa.  “These taxa may be declining in a significant part of their range in New England, or may have one or more occurrences of biological, ecological, or possible genetic significance.  Division 3(a) are those taxa that have documented decline in a substantial portion of their range in New England, e.g. southern New England…. Division 3(b) taxa are those that, based on their biology and geography within New England, have populations that are disjunct to such a degree that genetic isolation is suspected….For Division 3(b), only selected occurrences in a particular state are of conservation concern for the purposes of the Flora Conservanda list, not all occurrences of the taxon throughout New England.”  Only when a 3(a) or 3(b) status applies to Massachusetts is it listed in this column.
Division 4: Historical taxa.  Not observed in New England in the past 20 to 25 years.
Division Indeterminate (IND): Indeterminate taxa.  These taxa are under review; their regional status is not yet determined.

• MESA:  Legal status under the Massachusetts Endangered Species Act (MGL c. 131A).

E: Endangered
T: Threatened
SC: Special Concern

• State Rank:  These are the conservation status ranks as defined by NatureServe (NatureServe, 2014).  Ranks considered rare (S1 through S3S4) are in bold in the table above.

 

Subnational (S) Conservation Status Ranks

Status	Definition
SX	Presumed Extirpated—Species or community is believed to be extirpated from the state/province. Not located despite intensive searches of historical sites and other appropriate habitat, and virtually no likelihood that it will be rediscovered.
SH	Possibly Extirpated (Historical)—Species or community occurred historically in the state/province, and there is some possibility that it may be rediscovered. Its presence may not have been verified in the past 20-40 years. A species or community could become SH without such a 20-40 year delay if the only known occurrences in a state/province were destroyed or if it had been extensively and unsuccessfully looked for. The SH rank is reserved for species or communities for which some effort has been made to relocate occurrences, rather than simply using this status for all elements not known from verified extant occurrences.
S1	Critically Imperiled—Critically imperiled in the state/province because of extreme rarity (often 5 or fewer occurrences) or because of some factor(s) such as very steep declines making it especially vulnerable to extirpation from the state/province.
S2	Imperiled—Imperiled in the state/province because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the state/province.
S3	Vulnerable—Vulnerable in the state/province due to a restricted range, relatively few populations (often 80 or fewer), recent and widespread declines, or other factors making it vulnerable to extirpation.
S4	Apparently Secure—Uncommon but not rare; some cause for long-term concern due to declines or other factors.
S5	Secure—Common, widespread, and abundant in the state/province.
SNR	Unranked—State/province conservation status not yet assessed.
SU	Unrankable—Currently unrankable due to lack of information or due to substantially conflicting information about status or trends.
SNA	Not Applicable —A conservation status rank is not applicable because the species is not a suitable target for conservation activities.
S#S#	Range Rank —A numeric range rank (e.g., S2S3) is used to indicate any range of uncertainty

 

• Other Concerns/Comments:
  • The RSGCN ranks – low, moderate, high, very high – for regional responsibility and regional concern are derived from Terwilliger Consulting and Northeast Fish and Wildlife Diversity Technical Committee, 2013.  These ranks are only available for vertebrates, freshwater mussels, tiger beetles, and federally listed invertebrates.
  • Birds: These notes refer to selected information from the Massachusetts Breeding Bird Atlas, the Breeding Bird Surveys, and various bird conservation plans, where the information influenced the decision to list a species as a SGCN.
  • Synonyms: Recently or commonly used scientific name synonyms are listed here.  If the SGCN is listed under MESA, the names used on the MESA list are given precedence.
  • Other notes are given if relevant to selection as a SGCN.
