";s:4:"text";s:4478:"Ontario has some of the largest global populations of the Eastern Prairie Fringed-orchid (Oldham 2000), with 16 extant populations (The following sections address specific requirements of The Ontario Ministry of Natural Resources posted the provincial recovery strategy for this species on the Environmental Bill of Rights (Based on the following four criteria outlined by Government of Canada (2009), there are unknowns regarding the feasibility of recovery of the Eastern Prairie Fringed-orchid. Drainage and development pose a threat to the habitat of this species in both Canada and the United States (Bowles 1993), unless used as part of a restoration or recovery program for Eastern Prairie Fringed-orchid habitat. At least two populations are well known locally and accessible to naturalists and photographers, although trampling has not been directly observed.
Bulletin 48. The 26 sites described as critical habitat represents 13 of the 16 extant populations. Since this ranking study was completed, however, new sites have been discovered and the status of other sites has changed. Recovery Plan prepared for the U.S. Fort Snelling, Minnesota. A Population Genetic Analysis of Platanthera leucophaea in Northern Illinois.
American Midland Naturalist 154 (2): 273-285.Brownell, V.R. Zettler, J.W. This orchid’s microhabitat has been described in Ontario as existing in three general areas: fens, tallgrass prairie and moist old fields (S. Brinker It is also recommended that the habitat regulation be written so that it is flexible enough to immediately protect newly discovered occurrences, using a similar site-specific approach for habitat delineation.Open bedrock mineral shoreline fen dominated by Fresh Water Cordgrass (Spartina pectinata), Twig Rush (Cladium mariscoides), Switch Grass (Panicum virgatum), Kalm Open Northern White Cedar (Thuja occidentalis)-Tamarack (Larix laricina) peatland fens with sedges (Carex Deep peat-based organic soils in open graminoid fens with the following associated species: Wire Sedge, Yellow Sedge (Carex flava), Common Reed (Phragmites australis Deep peat-based organic soils in open graminoid fen dominated by sphagnum mosses, Wire Sedge, Coast Sedge (Carex exilis), Swamp Birch, Leatherleaf and Tamarack. Ontario Recovery Strategy Series. Relatively little research has occurred on Canadian populations, however, and much remains unknown about them.Effects of fire: The Eastern Prairie Fringed-orchid adapts to disturbances, such as fire, while dormant, but damage during the growing season may affect plant survival (U.S.
