  • Rare Native Animals of RI
    RARE NATIVE ANIMALS OF RHODE ISLAND Revised: March, 2006 ABOUT THIS LIST The list is divided by vertebrates and invertebrates and is arranged taxonomically according to the recognized authority cited before each group. Appropriate synonomy is included where names have changed since publication of the cited authority. The Natural Heritage Program's Rare Native Plants of Rhode Island includes an estimate of the number of "extant populations" for each listed plant species, a figure which has been helpful in assessing the health of each species. Because animals are mobile, some exhibiting annual long-distance migrations, it is not possible to derive a population index that can be applied to all animal groups. The status assigned to each species (see definitions below) provides some indication of its range, relative abundance, and vulnerability to decline. More specific and pertinent data is available from the Natural Heritage Program, the Rhode Island Endangered Species Program, and the Rhode Island Natural History Survey. STATUS. The status of each species is designated by letter codes as defined: (FE) Federally Endangered (7 species currently listed) (FT) Federally Threatened (2 species currently listed) (SE) State Endangered Native species in imminent danger of extirpation from Rhode Island. These taxa may meet one or more of the following criteria: 1. Formerly considered by the U.S. Fish and Wildlife Service for Federal listing as endangered or threatened. 2. Known from an estimated 1-2 total populations in the state. 3. Apparently globally rare or threatened; estimated at 100 or fewer populations range-wide. Animals listed as State Endangered are protected under the provisions of the Rhode Island State Endangered Species Act, Title 20 of the General Laws of the State of Rhode Island.

  • Boreal Snaketail
    Species Status Assessment Class: Insecta Family: Gomphidae Scientific Name: Ophiogomphus colubrinus Common Name: Boreal snaketail Species synopsis: As its name implies, the boreal snaketail (Ophiogomphus colubrinus) is a species of northern distribution, and it has the most northern range of any clubtail (Mead 2003). The range extends from the western provinces of British Columbia and Alberta, eastward across Canada, to Ontario, Quebec, and New Brunswick. In the United States, it occurs in Maine, New Hampshire, and New York, as well as in Michigan, Wisconsin, Minnesota, and Wyoming (Needham et al. 2000). O. colubrinus was first documented in New York in 1995, with a number of subsequent records in 1996. All of these records are from the Ausable River in the central Adirondacks, including both the East and West Branch. Some of the recorded locations were documented only by the collection of exuviae. Although the original New York location, the Ausable River along Riverside Drive near Lake Placid, and nearby stretches of the Ausable were searched on several occasions, presence was not documented during the New York State Dragonfly and Damselfly Survey (NYDDS). There is no evidence that changes have occurred in the Ausable River in the vicinity of the previously documented records, so additional surveys would be desirable to confirm the continued presence of this species in New York (White et al. 2010). Previously recorded locations for O. colubrinus in New York are on rivers, principally nearer to the headwaters where the rivers are rapid and shallow with sand, gravel, rock, and boulder substrate, and are primarily bordered by trees and shrubs (New York Natural Heritage Program 2010).

  • NYSDEC SWAP High Priority SGCN Dragonflies Damselflies
    Common Name: Tiger spiketail SGCN – High Priority Scientific Name: Cordulegaster erronea Taxon: Dragonflies and Damselflies Federal Status: Not Listed Natural Heritage Program Rank: New York Status: Not Listed Global: G4 New York: S1 Tracked: Yes Synopsis: The distributional center of the tiger spiketail (Cordulegaster erronea) is in northeastern Kentucky in the mixed mesophytic forest ecoregion, and extends southward to Louisiana and northward to western Michigan and northern New York. New York forms the northeastern range extent and an older, pre-1926 record from Keene Valley in Essex County is the northernmost known record for this species. Southeastern New York is the stronghold for this species within the lower Hudson River watershed in Orange, Rockland, Putnam and Westchester counties and is contiguous with New Jersey populations (Barlow 1995, Bangma and Barlow 2010). These populations were not discovered until the early 1990s and some have remained extant, while additional sites were added during the New York State Dragonfly and Damselfly Survey (NYSDDS). A second occupied area in the Finger Lakes region of central New York has been known since the 1920s and was rediscovered at Excelsior Glen in Schuyler County in the late 1990s. During the NYDDS, a second Schuyler County record was reported in 2005 as well as one along a small tributary stream of Otisco Lake in southwestern Onondaga County in 2008 (White et al. 2010). The habitat in the Finger Lakes varies slightly from that in southeastern New York and lies more in accordance with habitat in Michigan (O’Brien 1998) and Ohio (Glotzhober and Riggs 1996, Glotzhober 2006)—exposed, silty streams flowing from deep wooded ravines into large lakes (White et al.
