Jefferson Salamander Range Jefferson Salamander Jefferson Salamanders Pictures of Jefferson Salamander Published on March 7th 2017 by staff under Salamanders. Support conservation, agency, municipal and industry partners to undertake activities to protect and recover the Jefferson Salamander. 2010. Factors affecting the Jefferson Salamander include the limited availability of the habitats required by the species, namely, vernal pools or fishless wetlands in woodlands for breeding, and loose, moist soils in deciduous or mixed woodlands in terrestrial sites for burrowing. The operation of heavy equipment and heavy use of ATVs (e.g., repeated travel along a path) to the extent that the activity results in the loss of vegetation or microhabitat features, alteration of vernal pool hydrology, or filling, sedimentation or pollution of vernal pools, could destroy, damage or isolate/fragment breeding or terrestrial habitat. Field investigations revealed four populations of Jefferson Salamander. The global range (figure 1) is based on limited data, and occurrences in many regions still require genetic confirmation.

Migratory movements occur in a variety of habitats, including woodlands, plantations, agricultural fields and early successional areas, and across roads. American Museum Novitates No. Recovery Strategy for the Jefferson Salamander (Ambystoma jeffersonianum) in Canada [Proposed]. Blue-spotted Salamanders (Ambystoma laterale) and laterale-dominated polyploids are the other members of the complex. The listed coordinates are a cartographic representation of where critical habitat can be found, presented as the southwest corner of the 1 x 1 km standardized UTM grid square containing all or a portion of the critical habitat. Ontario Ministry of Natural Resources (OMNR). These markers may also address other questions regarding population dynamics and genetics that involve the unisexual part of the complex. These masses are much looser and more gelatinous compared to those of the Spotted Salamander (Ambystoma maculatum), which often occurs in the same ponds. Home range, migratory movements and habitat use of Jefferson Salamander complex in Southern Ontario as determined by radio telemetry. Scientific Name: Ambystoma jeffersonianum complex Range and Habitat: West of Connecitcut River, located in Lichfield County and Fairfield County. Where breeding ponds that support Jefferson Salamander are not known (or not available in existing wetland habitat mapping), a generalized area (represented by a radial distance around an observation record (300 m, and 1 km where appropriate; see habitat regulation)) is used to represent the habitat and direct recovery and protection activities until information allowing identification of more detailed critical habitat boundaries is obtained. Addition of carnivorous fish to breeding ponds. A defining feature of vernal pools is that they usually dry by the middle of the summer; some vernal pools, however, may dry only every couple of years. Larval mortality is also high among polyploid individuals (Bogart and Licht 1986). 6. The Jefferson Salamander was first recognized to occur in Canada by Weller and Sprules in 1976. 2015. Global range for the Jefferson Salamander (NatureServe 2005) Note: This map is based on Element Occurrence (EO) records, which represent specific locality data that are developed and maintained by individual provincial and state natural heritage programs. Impacts from development include site clearing and grading that alter cover, topography and drainage patterns; stormwater management and increases in impervious cover that alter natural hydroperiod regimes; alteration of the water balance of adjacent wetlands and the moisture content of soils; and silt fencing that prevents and/or hinders migration of salamanders. T… Most of the individuals across the range of both species are likely hybrids (Klemens 1993). The recovery strategy for Jefferson Salamander was completed on February 18, 2010. They would help in obtaining more information on Jefferson Salamander overwintering sites, use of terrestrial habitat and microhabitats, communal or individual use of sites, and so on. Journal of Experimental Zoology 264:93-99. The species range was mapped in 1991 as shown above. Terrestrial habitat includes all of the areas and features described above that extend radially 300 m from the edge of the breeding pond. 2009. Terrestrial habitat that meets these requirements should be included within the habitat regulation. Handbook of Salamanders. For copies of the recovery strategy, or for additional information on species at risk, including COSEWIC Status Reports, residence descriptions, action plans, and other related recovery documents, please visit the Species at Risk Public Registry. 2008. Within breeding ponds the Jefferson Salamander requires low shrubs, twigs, fallen tree branches, submerged riparian vegetation or emergent vegetation to which to attach egg masses. Information gathered through this project will contribute to the understanding of groundwater contributions to the breeding pond, and of habitat impacts associated with use of recreational trails. The Jefferson Salamander is one of Vermont’s three mole salamanders. Therefore, statements in the provincial recovery strategy referring to protection of the species' habitat may not directly correspond to federal requirements, and are not being adopted by Environment Canada as part of the federal recovery strategy. The federal recovery strategy for the Jefferson Salamander in Canada consists of three parts: Part 1 – Federal Addition to the Recovery Strategy for the Jefferson Salamander (Ambystoma jeffersonianum) in Ontario, prepared by Environment Canada. Furthermore, breeding may not occur at a pond every year (Weller 1980). Genetics and systematics of hybrid species. Thompson, E. L., J. E. Gates, and G.S. Environment Canada adopts the description of the Jefferson Salamander habitat under section 28 of Ontario Regulation 242/08Footnote10 made under the provincial ESA as the critical habitat in this federal recovery strategy. For breeding to be successful, suitable egg attachment sites must be available, and the pond must contain an adequate amount of food. Known occurrences, collected specimens and observations of mole salamanders. The Reptiles and Amphibians of the Hamilton Area: An Historical Summary and the Results of the Hamilton Herpetofaunal Atlas. Description: Slimy Salamanders were once considered one species (P. glutinosus) but have recently been split into 13 separate species.They all look similar and are best differentiated by range. Weller, W.F., and W.G. The recovery goal is to ensure that existing threats to populations and habitat of the Jefferson Salamander are sufficiently removed to allow for the long-term persistence and expansion of the species within its existing Canadian range. 46 pp. As soon as a species is listed as extirpated, endangered or threatened under the ESA, it is automatically protected from harm or harassment. At other times of the year, it remains largely underground, beneath logs or in burrows. Mole salamanders spend most of their lives underground (like moles) except when migrating to and from breeding pools and ponds. Note: This map is based on Element Occurrence (EO) records, which represent specific locality data that are developed and maintained by individual provincial and state natural heritage programs. Licht, and L.A. Lowcock, 1992. Most often, these salamanders are associated with deciduous or mixed woodlands. Jefferson Salamanders appear to have strong site and pond fidelity, and are long-lived (up to 30 years) (Weller 1980; Thompson et al. Activities described in Table 2 are examples of those likely to cause destruction of critical habitat for the species; however, destructive activities are not necessarily limited to those listed. 2010. Jefferson's Salamanders have a pond-type larva with a tall tail fin and bushy external gills. Website: (http://www.natureserve.org/explorer/ranking.htm#globalstatus) [accessed 25 April 2014]. A species that is native to the wild in Ontario but is facing imminent extinction or extirpation. Its current global conservation status rank is G4 (NatureServe 2008), which indicates that the species is apparently secure within its range. Ottawa. The Ministry can also advise whether any authorizations under the ESA or other legislation may be required for undertaking the project. In place of section 2, Environment Canada is establishing a population and distribution objective and performance indicators, is adopting the government-led and government-supported actions of the Jefferson Salamander Ontario Government Response StatementFootnote1 (Part 3) as the population and distribution objective and the broad strategies and general approaches to meet the population and distribution objective; and is adopting the habitat regulated under Ontario's Endangered Species Act, 2007 as critical habitat for the Jefferson Salamander. Habitat alterations that would adversely affect the species should be discouraged. It hides in burrows beneath leaf litter, under logs and other surface objects such as rocks. 2003. Documented Locations of the Jefferson Salamander in Ontario, Table 1. The population and distribution objective established by Environment Canada for the Jefferson Salamander is to: Maintain, and to the extent that it is biologically and technically feasible, increase the species' area of occupancy within its existing Ontario range. Therefore, genetic analysis is often required to distinguish pure Jefferson Salamanders from polyploids, and particularly to distinguish pure female Jefferson Salamanders. Objective: Evaluate and implement threat mitigation and habitat restoration techniques. If this activity occurs within critical habitat core areas at any time of the year, with the exception of winter months when the ground is snow covered and frozen, it is highly likely to have direct effects on critical habitat. 1980. 1997. Prey in the terrestrial habitat includes insects, earthworms and other invertebrates. Figure 1. Version 7.1. 587 pp. strategy for the Jefferson Salamander in accordance with the requirements of the Endangered Species Act ... Canadian range. Connecticut, Maryland, New Jersey, West Virginia, Identify and monitor extant populations of the Jefferson Salamander in Canada, Apply research findings on the species' movements and habitat use to ensure protection of habitat, Identify historic populations/sites with the potential for enhancement or restoration (e.g., recovery habitat), Develop a communication strategy to inform municipalities, planners, the development industry, property managers and other stakeholders of the habitat mapping and protection requirements for the Jefferson Salamander under the, Develop and evaluate mitigation and restoration techniques employed to address threats, Population and habitat monitoring/ research, Description of habitat recommended for regulation under the ESA 2007, Restoration and enhancement of historic sites, Project Coordinator, Terrestrial Field Inventories, Recovery Strategy for the Jefferson Salamander (Ambystoma jeffersonianum) in Canada - 2015 [Proposed]. Such historical identifications of the Jefferson Salamander, as well as available museum records, are, however, not necessarily accurate. Species at Risk Act Policy and Guidelines Series. Website: (http://www.natureserve.org/explorer) [accessed 25 April 2014]. Within dispersal corridors it is most important to maintain habitat permeability (movement through connective habitat to access adjacent core areas) and, as a result, certain activities that are likely to cause destruction in core areas may not cause destruction in corridors so long as sufficient habitat permeability is maintained.
