Unpublished report, 13 pp. Burning during the dormant season or in years when rainfall in the growing season is high would probably promote flowering in tallgrass prairie wetlands and possibly in fens. Riley, J.L. Suitable habitat for the Eastern Prairie Fringed-orchid in Ontario is rare and has likely never been abundant; habitat is probably limiting for this species due to its very narrow habitat preference (COSEWIC 2003). The Eastern Prairie Fringed-orchid is considered to be globally imperiled; it is rare and declining throughout its range in eastern North America. Common Reed has historically been present at the Phragmites fen in the Marlborough Forest and is not believed to present a threat at this location. Oldham, M. 2000. It is unknown whether the timing, frequency or intensity of the fire has had any impact on the apparent decline of the Eastern Prairie Fringed-orchid at Ojibway Prairie. Jacobs. Six additional sites with suitable habitat were also visited, but no plants were observed. COSEWIC assessment and update status report on the eastern prairie fringed-orchid Platanthera leucophaea in Canada. Thanks also to the many individuals who provided technical expertise to assist in developing the recovery strategy for this species, including Marlin Bowles of the Morton Arboretum, June Keibler of The Nature Conservancy, Dr. Larry Zettler of Illinois College and Dr. Pati Vitt of the Chicago Botanic Garden. These are specific actions designed to avoid "take" (mortality) of this species. NHIC (Natural Heritage Information Centre). Stewart, M.L. However, in areas of the state where frozen conditions are unreliable, very dry soils late in the growing season might be the best available alternative. Shallow peat and marl deposits over bedrock in open graminoid fen dominated by Fresh Water Cordgrass (Spartina pectinata), Twigrush, Switch Grass (Panicum virgatum), Tufted Hairgrass (Deschampsia cespitosa), Little Green Sedge (Carex viridula), Bald Spikerush (Eleocharis erythropoda), Common Sneezeweed (Helenium autumnale), Silverweed (Potentilla anserina), Four-flowered Loosestrife (Lysimachia quadriflora), Rush Aster (Symphyotrichum boreale), Hooded Ladies'-tresses (Spiranthes romanzoffiana) and Blueflag. Address inconsistencies in naming and geographical referencing of populations and sub-populations to permit comparative analyses of population trends. Some aspects of the status and ecology of seven rare wetland plant species in the Chicago region of northeastern Illinois. Deer will graze on the flowering stems, and are sometimes abundant in habitats where the orchid grows, but the magnitude of this potential threat is currently unknown. Government of Canada. 2004. Deep peat based organic soils in open graminoid fen dominated by sphagnum mosses, Wire Sedge, Coast Sedge (Carex exilis), Swamp Birch, Leatherleaf, and Tamarack. Increases in the availability of nutrients (nitrogen, phosphorus) resulting from nutrient-rich agricultural runoff may be causing habitat change, especially at poor fen sites (Marlborough Forest, Minesing Swamp and Holland Marsh) where nutrient levels are naturally low. All Canadians are invited to join in supporting and implementing this strategy for the benefit of the Eastern Prairie Fringed-orchid and Canadian society as a whole. Seed Viability and Germination of the Federal Threatened Eastern Prairie Fringed Orchid Platanthera leucophaea (Nuttall) Lindley. Committee on the Status of Species at Risk in Ontario (COSSARO): The committee established under section 3 of the Endangered Species Act, 2007 that is responsible for assessing and classifying species at risk in Ontario. Accessed January 24, 2007. 38 pp. The fen and prairie habitats where this orchid is found are often habitats for other species at risk, and the protection of such habitats also benefits these other species. Southern Ontario bogs and fens off the Canadian Shield. The morphology of seed germination in Cymbidium dayanum Reichb (, Species at Risk: Eastern Prairie Fringed-orchid, NatureServe Explorer: An online encyclopedia of life, Illinois, Indiana, Iowa, Maine, Michigan, Virginia. Eastern Prairie Fringed-orchid Recovery Team. The four largest populations are very widely separated. It is therefore possible that suitable habitat contains additional plants not observed during monitoring years and young plants that may take years to emerge above ground.

Consult with a biologist, if needed. 2003. 1 a wildlife species facing imminent extirpation or extinction, 2 species that lives in the wild in Ontario but is facing imminent extinction or extirpation, 3 at high risk of extinction or elimination due to very restricted range, very few populations, steep declines, or other factors, 4 at moderate risk of extinction or elimination due to a restricted range, relatively few populations, recent and widespread declines, or other factors, 5 persistence as an underground plant that relies on root fungi for nourishment, 6 plants in the family Ericaceae, the heath family. It is also listed as endangered on the Species at Risk in Ontario (SARO) List, as federally endangered in Canada by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and as federally threatened in the United States. Damage by recreational vehicles is known to have occurred at two sites at least. Bulletin 48. Symbiotic seed germination and mycorrhizae of federally threatened Platanthera praeclara. 251 pp. Chang, C., Y.C. Open Northern White Cedar (Thuja occidentalis)-Tamarack (Larix laricina) peatland fens with sedges (Carex spp. Unpublished report to Ontario Ministry of Natural Resources Kemptville District. Michigan Natural Features Inventory, Lansing, Michigan. Monitoring of the Eastern Prairie Fringed-orchid (as well as many other plant species at risk) has also occurred there in the past several years. Schedule of Studies to Identify Critical Habitat, NatureServe Explorer: an online encyclopedia of life, Natural Heritage Information Centre Biodiversity Explorer Species Report for Platanthera leucophaea (Eastern Prairie Fringed-orchid), Midewin National Tallgrass Prairie web site, 1.1 Species Assessment and Classification, 1.3 Distribution, Abundance and Population Trends, 1.6 Recovery Actions Completed or Under Way, 2.5 Area for Consideration in Developing a Habitat Regulation, Recovery Strategy Development Team Members, Figure 1. Under the ESA 2007, a recovery strategy must include a recommendation to the Minister of Natural Resources on the area that should be considered in developing a habitat regulation. This orchid is also found in a range of soil types, including deep, black calcareous silt loams, organic silty clay loams, and muck soils (Zambrana Engineering Inc. 1998). White-tailed deer (Odocoileus virginianus) have been observed grazing on flowering stems of the Eastern Prairie Fringed-orchid, and deer are abundant or increasing in population at some sites that the Eastern Prairie Fringed-orchid occupies (COSEWIC 2003, J. Haggeman pers. Since seedlings may not emerge above the soil for many years, this association is important in sustaining the plant before leaves develop and photosynthesis begins. The ecological risks of such activities must be considered individually before undertaking them, in order to reduce possible negative effects. NatureServe, Arlington, Virginia. Également disponible en français sous le titre « Programme de rétablissement de la platanthère blanchâtre de l’Est (Platanthera leucophaea) au Canada », © Her Majesty the Queen in Right of Canada, represented by the Minister of the Environment, 2012. Such information can help predict Eastern Prairie Fringed-orchid population trends, and allow recovery efforts to be focused where pollinators are present. The Eastern Prairie Fringed-orchid is very inconspicuous, and trampling by humans is probably a threat to several populations. Report to the U.S. Eastern Prairie White Fringed Orchid (Platanthera leucophaea), a Wisconsin Endangered and Federal Threatened plant, is found in moist, undisturbed, deep-soiled and/or calcareous prairies and rarely in tamarack fens. Mesic tallgrass prairie over fine or loamy sand with a combination of species such as Prairie Dock (Silphium terebinthinaceum), bentgrass (Agrostis spp. The species has been listed as federally threatened in the United States since 1989 (Oldham 2000). Report regularly on the status of this species, using the best available scientific information. Today, 21 populations of a total of 32 reported occurrences are believed to be current or extant in Ontario (figure 2), and the remaining 11 are considered historic (not confirmed for 20 years) or extirpated (COSEWIC 2003). 1992.
