The Canadian distribution accounts for about 5% of the global range and includes a small area in the Niagara Gorge in Ontario, three large areas in Quebec (the Adirondack Piedmont, the Appalachian uplift, and the north shore April 2012. Throughout its US range, D. fuscus is mostly secure (NatureServe 2010). HAIRSTON, N. G. 1987. 1993). Ultimately, NCC wishes to protect a total of 101.17 km² in the centre of these mountains and establish a surrounding buffer zone of 303.51 km² (NCC 2008). It is currently on a list of species likely to be designated Threatened or Vulnerable by the provincial government (MRNF 2010). Correlation of the habitats of amphibians with their ability to survive the loss of body water. Caractérisation de l'habitat d'une communauté de salamandres de ruisseaux comportant des hybrides. SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. Toner, Maureen – Biologiste, Programme des espèces en péril, Direction de la faune et des poisons, Ministère des Ressources naturelles et de l'Énergie, Fredericton, New Brunswick. Current forest management practices are increasingly converting natural mixed forests to conifer plantations (Erdle and Pollard 2002). Journal of Biogeography 2: 253-263. 1980b. The Northern Dusky Salamander is a grayish-brown salamander that is noticeably chunkier than the Northern Two-lined Salamander that they often share their habitat with. Environmental Management 30: 225-233. Along the St. Lawrence Valley, numerous residential developments are ongoing, especially near Quebec City. 2010). 2005. 44 p. + appendices. Protection des espèces menacées ou vulnérables en forêt publique - Les salamandres de ruisseaux : la salamandre pourpre (Gyrinophilus porphyriticus), la salamandre sombre des montagnes (Desmognathus ochrophaeus) et la salamandre sombre du Nord (Desmognathus fuscus). These two DUs are completely isolated from one another, but it is unknown for how long they have been separated or whether they have differentiated genetically. Human activities (urbanization, logging, road construction) that affect water supply and quality, as well as microhabitat quality and availability, are the major threats to D. fuscus in Canada. 1. The Niagara Gorge population is over 30 km away from the nearest US population in New York State, and separated by important geographical barriers such as the Niagara River (Bishop 1941, Kamstra 1990, COSEWIC 1999). JUTERBOCK, J. E. 1978. 2008. JUTERBOCK, J. E. 1990. The species distribution maps show the known range of each species found in New York. Although the guidelines have now been revised, fish introduction still occurs in Quebec and represents a threat to stream salamanders (W. Bertacchi, pers. Although it is hard to determine whether these developments are directly reducing the Northern Dusky Salamander's habitat; they are located within watersheds where the species occurs and all require the construction of access roads.
