The Rare Species Status List is the New York Natural Heritage Program's current assessment of the status of New York's rarest and most imperiled animal species. We have developed this list over the years in consultation with the Department of Environmental Conservation's Endangered Species and Nongame Units, NatureServe, researchers, conservation organizations, and knowledgeable amateur biologists. Population locations in our database are drawn from sources including museum specimens, personal contacts, and the scientific literature, and through extensive field research. This list is dynamic, meaning it changes as new discoveries are made or populations are lost.
Species typically have two sets of names: scientific and common. Scientific names follow standard nomenclatures specific to the different groups of animals. The scientific names of birds, for example, follow the standards set by the American Ornithologists' Union.
Common names are standardized in some cases, such as for birds, but are not as consistent across a species' geographic range as scientific names. Further, some species have not yet been given common names; in the list below, these species are flagged with general names, such as "A Bluet Damselfy" or "A Noctuid Moth".
NY Natural Heritage tracks a selected subset of New York's animals. The species we track are chosen based on their degree of rarity or imperilment within the state, and as new information comes in, new species are sometimes added while others are discontinued. Information on the species and communities tracked by NY Natural Heritage are used for conservation, research, and regulatory purposes.
Many of the species tracked by NY Natural Heritage are listed as "endangered" or "threatened" under the state Environmental Conservation Law (E.C.L.). Listing is a legal process that is conducted by the state agency with authority over the species in question, and for animals confers important protection requirements. See the List Of Endangered, Threatened And Special Concern Fish and Wildlife Species Of New York State for all state-listed animals.
The DEC Division of Fish, Wildlife, and Marine Resources has jurisdiction over rare animal species listed as "endangered", "threatened", or "special concern" under E.C.L. §11-0535. Animals listed as endangered or threatened receive notable legal protection, as it is illegal to take or possess any of these species or their parts without a permit from DEC. Species of special concern warrant attention and consideration but current information does not justify listing them as either endangered or threatened.
A subset of the animal species listed under New York state law is also recognized under federal law. These species are so seriously imperiled across their entire range that they face the very real prospect of extinction. Species are listed as federally endangered or threatened by the U.S. Fish and Wildlife Service in consultation with state agencies and other experts, and the Service works closely with DEC on the protection of federally listed species in New York.
Ultimately, protection of New York's biodiversity lies with landowners and land managers regardless of state or federal listings. How private and public landowners manage their properties will determine what species and natural communities persist into the future. This situation is both a great opportunity and a serious challenge.
State legal listings are identified with the following codes:
Federal legal listings are identified with the following codes:
Another state designation is Species of Greatest Conservation Need (SGCN), which was developed as part of the state's wildlife action plan. In the following list, SGCN are coded as follows:
See the State Wildlife Action Plan (SWAP) for a list of the state's SGCN and definitions of the three categories.
NY Natural Heritage's statewide inventory efforts revolve around lists of rare species and all types of natural communities known to occur, or to have historically occurred, in the state. These lists are based on a variety of sources including museum collections, scientific literature, information from state and local government agencies, regional and local experts, and data from neighboring states.
Each rare species is assigned a rank based on its rarity, population trends, and threats. Like those in all state Natural Heritage Programs, NY Natural Heritage's ranking system assesses rarity at two geographic scales: global and state. The global rank (G-rank) reflects the status of a species or community throughout its range, whereas the subnational rank (S-rank) indicates its status within New York. Global ranks are maintained and updated by NatureServe, which coordinates the network of Natural Heritage programs. Both global and subnational ranks are usually based on the range of the species or community, the number of occurrences, the viability of the occurrences, and the vulnerability of the species or community around the globe or across the state. As new data become available, the ranks may be revised to reflect the most current information. Subspecific taxa are also assigned a taxon rank, which indicates the subspecies' rank throughout its range.
For the most part, global and subnational ranks follow a straightforward scale of 1 (rarest/most imperiled) to 5 (common/secure), as follows:
There are some additional codes:
Codes sometimes have qualifiers attached:
Global | State | Example | Explanation |
---|---|---|---|
G5 | S2 | Devil Crawfish | Common rangewide (G5), imperiled in NY (S2) |
G3 | S2 | Bog Turtle | Uncommon rangewide (G3), imperiled in NY (S2) |
G5 | S1S2 | Swamp Darter | Common rangewide (G5), uncertain whether critically imperiled (S1) or imperiled (S2) in NY |
G5 | S1S3 | Watercress Snail | Common rangewide, uncertain whether critically imperiled (S1), imperiled (S2), or uncommon (S3) NY |
GH | SX | Shortnose Cisco | Historical rangewide (GH), extirpated from NY (SX) |
GU | SH | Black Lordithon Rove Beetle | Insufficient information for ranking the species' rangewide status (GU), historical in NY (SH) |
G4 | S1? | Chain Fern Borer Moth | Apparently secure rangewide (G4), appears to be critically imperiled in NY (S1) but more information is needed (?) |
G1G2 | S1 | Dwarf Wedgemussel | Somewhere between critically imperiled (G1) and imperiled (G2) rangewide, critically imperiled in NY (S1) |
G3G4 | S1S3 | Bird Dropping Moth | Uncertain whether uncommon (G3) or apparently secure (G4) rangewide, uncertain whether critically imperiled (S1), imperiled (S2), or uncommon (S3) in NY |
G5T2 | S1 | Karner Blue Butterfly | The species is secure (G5) but the subspecies is imperiled rangewide (T2), the subspecies is critically imperiled in NY (S1) |
G4T2T4 | SH | The Consort Underwing | The species is apparently secure (G4) but the subspecies is either imperiled (T2), uncommon (T3), or apparently secure (T4) rangewide, the subspecies is historical in NY (SH) |
G1Q | S1 | Bogbean Buckmoth | Critically imperiled rangewide (G1) but the species is in taxonomic dispute (Q), critically imperiled in NY (S1) |
G5 | S3B,S1N | Least Bittern | Common rangewide (G5), breeding populations (B) are uncommon in NY (S3) while non-breeding populations (N) are critically imperiled (S1) (in this case, overwintering birds) |
G5 | S2S3B,S2N | Bald Eagle | Common rangewide (G5), breeding populations (B) are either imperiled (S2) or uncommon (S3) in NY, while non-breeding birds (N) are imperiled in NY |
NY Natural Heritage tracks all species listed as endangered and threatened. While we track many of the species listed as being of special concern, a subset of special concern species are currently not rare or imperiled enough to merit tracking at our precise scale. In addition, we track many species that are biologically rare and imperiled (nearly all S1 and S2 species, and some S3 species), but that have not gone through the review process necessary for state listing.
Our program keeps two lists of rare animal species: the Active Inventory List and the Watch List. Species on the Active Inventory List are ones we currently track in our database; for the most part these are the most rare or most imperiled species in the state. Species on the Watch List are those that could become imperiled enough in the future to warrant being actively inventoried, or are ones for which we do not have enough data to determine whether they should be actively inventoried. The lists are dynamic, as S-ranks change with unearthed historical information, field inventories reveal new populations or local extirpations, and state and federal listings are updated.
Further, we are assessing the conservation status of new species groups, such as many marine taxa and insect pollinators, through ongoing projects that will undoubtedly add species to our lists. NY Natural Heritage currently tracks 474 animal species (plus six animal assemblages, which are extraordinarily rare, diverse, or abundant aggregations of multiple animal species). The balance of species among taxonomic groups reflects both the degree of imperilment of various taxa and the level of available knowledge about different groups.
