Sharma, J., L. W. Zettler, J. W. Van Sambeek, M. R. Ellersieck, and C. J. Starbuck. Fish and Wildlife Service 1996). The underlying bedrock of the area is sandstone, limestone, dolomite, and shale of the Jurassic Period (Anonymous 1994). Borkowsky, C.L. May meet Threatened D1 as the population is estimated to have < 1,000 mature individuals (during fluctuation minima including recent years’ counts). This is a positive step in protecting this rare species. Still, S.M., A. L. Frances, A.C. Treher, and L. Oliver. The eastern limit roughly corresponds to the Mississippi River (Bowles and Duxbury 1986; Watson 1989). 1953. Committee on the Status of Endangered Wildlife in Canada. Bjugstad. In addition, climate change is expected to cause more frequent periods of drought in the area. Cattle grazing reduces survival and reproduction of the western prairie fringed-orchid. Cuthrell, D.L., and D.A. Is the population “severely fragmented” i.e. Email correspondence with Bruce Bennett, 2 September 2016. Manitoba Mineral Resources Division. 23 pp. Pleasants, J.M. Although impacts of climate change on precipitation and temperature have been predicted, the degree to which timing or severity of late spring frosts may impact the population is unknown. Western Prairie Fringed Orchid sometimes goes by Habenaria leucophaea var. Annual haying can present another problem to long-term survival if done prior to seed capsule maturation and dehiscence. The central stem is light green, terete, glabrous, and somewhat stout. 2015). University of Minnesota Press, Minneapolis. Individual plants in Minnesota monitoring plots have persisted for as long as 25 years, including reappearances after presumed dormancy (Sather and Anderson 2010). Two fungi, Ceratorhiza pernacatena and Epulorhiza spp. It is essential that core populations of P. praeclara be designated and managed in accordance with practices that are known to enhance populations and habitats of this species. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. Westwood. Johnson J85-176 (MMMN), Vascular Plant Herbarium, Agriculture and Agri-Food Canada (DAO).26 July 1984, P.M. Catling & V.R. Platanthera praeclara, western white-fringed orchid. calculated that if all seeds grew into plants then the great grandchildren of a single ... Platanthera praeclara Photos courtesy of Hal Horwitz. Likewise, in the Sheyenne National Grassland, tagged plants were absent in subsequent years (Sieg and Ring 1995). Ottawa. 1996. [accessed October 17, 2015]. Email correspondence with Bruce Bennett, 2 September 2016. The Tall Grass Prairie Preserve has a burn regime of every 4-5 years in order to reduce the threat that lack of disturbance poses to Western Prairie Fringed Orchid. The studies by Sharma et al. long. Prepared for the Endangered Plant and Invertebrates of Canada Project, Canadian Nature Federation, Ottawa. Additionally Hermit Sphinx (Lintneria eremitus ) (Harris et al. With the continued development of the shoot and chlorophyll, the plant becomes photosynthetic and somewhat autotrophic (Hadley 1982).
