District Ecologist, Kemptville District, Ministry of Natural Resources, Kemptville, Ontario. The pollination requirements of the Eastern Prairie Fringed-orchid are extremely specific. A rare plant management plan has also been completed for the park. (Because of the year-to-year variability in the emergence and flowering of this species, surveys must extend over two or more seasons. ), panic grasses (Panicum spp. 1999. Element Stewardship Abstract for Phragmites australis (Common Reed). The preferred habitat of the Eastern Prairie Fringed-orchid is very susceptible to invasion by several species. The plant produces seed capsules containing thousands of tiny seeds in late August and early September (Environment Canada 2006, COSEWIC 2003, U.S. Starbuck. Cuthrell, D.L., P.J. Fish and Wildlife Service 1996). Bulletin 48. Helpppp Is On The Way!! Version 1.8. Higman, and M.R. Bowles, M., K. Jacobs, L. Zettler, and T.W. In the Kemptville District of the Ontario Ministry of Natural Resources (OMNR), populations of the Eastern Prairie Fringed-orchid (Long Swamp Fen, Marlborough Forest - Phragmites Fen, and Marlborough Forest - Richmond Fen) have been monitored as resources permit (Thompson 2005, MacDonald 2004). Recovery Plan prepared for the U.S. Although hawkmoth studies have been completed in the United States, the hawkmoth species that visit Canadian populations of the Eastern Prairie Fringed-orchid are unknown. Blooming occurs early July through early August; fruiting occurs throughout August. Implementation of this strategy is subject to appropriations, priorities, and budgetary constraints of the participating jurisdictions and organizations. These efforts are beginning to pay off: In Illinois, the number of orchids has increased from 190 individuals in 1991 to 1,910 last summer. Currently, a snowmobile trail bisects one of the populations in eastern Ontario. Recovery strategy for the Eastern Prairie Fringed-orchid (Platanthera leucophaea) in Ontario. 2010.

Prescribed burning at Ojibway Prairie Provincial Nature Reserve has been carried out several times since 1982, and “wildfires” occurred regularly before then. Clearly, the conservation and management of these habitats is expected to benefit many species dependent on them. Other large populations are found in Bruce Peninsula National Park, Marlborough Forest (near Ottawa) and Minesing Swamp (Simcoe County). 66 pages. Other limiting factors include competition with alien invasive species, successional change, human impacts on water tables, and the collection of plants. Lack of competition from trees and shrubs allows for open conditions with full sunlight, which the Eastern Prairie Fringed-orchid requires for optimal growth and flowering (Bowles 1993). Van Sambeek, M. Ellersieck, and C. J. Starbuck. The Government of Ontario has demonstrated its commitment to protecting the Eastern Prairie Fringed-orchid by Thanks very much to Kristopher Lah of the Illinois U.S. NatureServe. It is recommended that areas with current or verified historic occurrences of the Eastern Prairie Fringed-orchid be considered in the development of a habitat regulation, that the habitat boundaries be delineated at a site-specific level on the basis of habitat descriptions provided in this strategy, and that the habitat regulation be written such that it is flexible enough to immediately protect newly discovered occurrences, using a similar, site-specific approach. Through the work of organizations such as Tallgrass Ontario and the Rural Lambton Stewardship Network, a variety of prairie species, including the Eastern Prairie Fringed-orchid, have been planted in an effort to restore communities (Hunt 2003). Genetic variation: Genetic variation among populations of the Eastern Prairie Fringed-orchid has been studied in Michigan, Ohio and Illinois (Wallace 2002, Havens & Bradford 2001, Havens & Buerkle 1999). This could result in population extinctions at some sites, especially those that are more upland in character. Federation of Ontario Naturalists, Don Mills, Ontario. As this is a work in progress, we welcome your suggestions and feedback. Jr. 1987. The recommendation provided below by the author will be one of many sources considered by the Minister when developing the habitat regulation for this species. Lindl. The Eastern Prairie Fringed-orchid requires full sunlight and little competition from surrounding vegetation, circumneutral soils and moist conditions. ), Dragon's Mouth (Arethusa bulbosa), Rose Pogonia (Pogonia ophioglossoides), Spotted Joe-pye Weed (Eupatorium maculatum), Boneset (Eupatorium perfoliatum), Labrador Tea (Ledum groenlandicum), Leatherleaf (Chamaedaphne calyculata), Narrow-leaved Meadow-sweet (Spiraea alba), Bog Goldenrod (Solidago uliginosa), Rough Goldenrod (Solidago rugosa), Red-osier Dogwood (Cornus stolonifera), Bog Rosemary (Andromeda polifolia), Marsh Bellflower (Campanula aparinoides), Tamarack and Northern White Cedar. Complete the ranking of sites, using new information collected, as more sites have been discovered and more information collected since the ranking study was conducted. Report to the Illinois Department of Natural Resources. 2005, Case 1987, Bowles 1983); the Eastern Prairie Fringed-orchid can tolerate pHs of between 5.3 and 7.5 (Zambrana Engineering Inc. 1998). Certain life history characteristics may also limit this orchid’s recovery. comm. 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. Specific details about the ecological role of the Eastern Prairie Fringed-orchid have not been described. 1993. The following sections address specific requirements of SARA that are not addressed in the Recovery Strategy for the Eastern Prairie Fringed-orchid (Platanthera leucophaea) in Ontario (Appendix 3), or augment, highlight or provide clarification. In 2007, this orchid was discovered at a new location in the Windsor area. St. Clair National Wildlife Area. vi + 30 pp. For enquiries, contact us. The Eastern Prairie Fringed-orchid is noted for dramatic, mass flowerings following several-year periods of apparent absence (COSEWIC 2003); accordingly, numbers of flowering plants can fluctuate annually by thousands. Eastern Prairie Fringed Orchid (Platanthera leucophaea) Ontario Ministry of Natural Resources Southern Region Monitoring Report 2003-04. NatureServe. The species requires full sunlight and is vulnerable to natural succession. It occurs east of the Mississippi River and in eastern Iowa. Chang, C., Y.C. Develop a scientifically defensible protocol for sampling, over several years, large populations and/or sparse populations that are spread over large areas. Hybrids have been documented at two sites in Ontario (Catling & Brownell 1999, Catling et al. Current global distribution of Eastern Prairie Fringed-orchid, Figure 2. Any … An evaluation and prioritization of populations of the Eastern Prairie Fringed-orchid has been undertaken to inform recovery actions (Brownell 2002). 2008. In other parts of Ontario, several turtle species at risk may be associated with the fen habitat of the Eastern Prairie Fringed-orchid. Fish and Wildlife Service for providing numerous reports and information relating to the Eastern Prairie Fringed-orchid. Sites in Ontario Containing Critical Habitat for the Eastern Prairie Fringed-orchid. The Eastern Prairie Fringed-orchid is listed as an endangered species under the ESA which protects both the plant and its habitat. 2002. Zettler, L.W., S.L. Fish and Wildlife Service. The recovery goal for the Eastern Prairie Fringed-orchid is to prevent any further loss of populations and habitat and habitat functionality, to reverse the declining population trends at extant locations and to restore occurrences at historic sites, where appropriate, within the species’ Canadian range. Critical habitat for the Eastern Prairie Fringed-orchid consists of the extent of contiguous suitable habitat surrounding known occurrences of the Eastern Prairie Fringed-orchid observed between 1990 and 2009 as per Appendix 2. Crosson, A.E., J.C. Dunford, and D.K. Its foliage and nectar are probably a source of food for herbivores and pollinators such as the species of hawkmoth that pollinates it. Habitat characteristics within major habitat types for Eastern Prairie Fringed-orchid, (modified from Eastern Prairie Fringed-orchid Recovery Team 2010). 1992, Bowles 1983). Zettler, L.W., S.L. The following descriptions summarize the habitat characteristics that have been documented from currently occupied sites. Mycorrhizal fungi and cold assisted symbiotic germination of the federally threatened eastern prairie fringed orchid, Platanthera leucophaea (Nuttall) Lindley. 2004. It grows in a wide variety of habitats, from mesic prairie to wetlands such as sedge meadows, marsh edges, even bogs. The Eastern Prairie Fringed-orchid’s rounded global status is Imperilled[3] (G2) (NatureServe 2009). 1999. Wallace, L.E. 16 pp. Common Name (population): Eastern Prairie Fringed-orchid. Oldham, M. 2000. Seedling survival is dependent on nutrients that mycorrhizal fungi supply (Zettler et al. Effects on the Environment and Other Species, Table 2. Confirm location and extent of populations. 2009. It is recognized that the critical habitat identified below is insufficient to achieve the population and distribution objectives for the species. The activities to obtain this information are outlined in the schedule of studies (Table 2). The 26 sites described as critical habitat represents 13 of the 16 extant populations. Lindl.] 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). 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. 20 pp. However, the Ontario Natural Heritage Information Centre now lists 16 current or extant populations (ONHIC 2010). It may not be possible to mitigate other threats such as: invasive species, changes to drainage patterns, successional changes, hybridization, grazing, long-term drought or flooding and threats to pollinators. Additional possible threats are hybridization and inbreeding due to small population sizes. ATV use has also been documented as a threat to orchid populations in Bruce Peninsula National Park. Species at Risk: Eastern Prairie Fringed-orchid. 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. The Eastern Prairie Fringed-orchid is ranked globally as imperilled (G2) (NatureServe 2009). The SEA concluded that this strategy will clearly benefit the environment and will not entail any significant adverse effects. 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. Despite being adapted for long-distance dispersal, it is doubtful that much genetic interaction between populations is occurring. Brownell, V.R. 251 pp. Examining the effects of fragmentation on genetic variation in Platanthera leucophaea (Orchidaceae): inferences from allozyme and random amplified polymorphic DNA markers. Sixteen extant populations of Eastern Prairie Fringed-orchid exist in the province of Ontario. The Eastern and the Western prairie fringed orchids were considered a single species until 1986. While drainage has been the greatest threat historically, flooding can also alter habitat and in some cases destroy it. Ontario Natural Heritage Information Centre (ONHIC). Extensive drying of soils at extant sites can result in dormancy of plants and, in some cases, mortality. Species at Risk in Ontario (SARO) List: The regulation made under section 7 of the Endangered Species Act, 2007 that provides the official status classification of species at risk in Ontario. U.S. Ontario Ministry of Natural Resources, Kemptville, Ontario. Please considering donating a photo to the Natural Heritage Conservation Program for educational uses. leucophaea, Orchis leucophaea. MacDonald, E. 2004. The species has been listed as federally threatened in the United States since 1989 (Oldham 2000). 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. Restore habitat and reintroduce the Eastern Prairie Fringed-orchid where appropriate and feasible. vi + 30 pp. Two plants were located at sites on the Crown land portion in the Holland Marsh in 2005. Reduce or eliminate threats at extant sites. : some aspects of their status, biology, and ecology and implications toward management. Minimize disturbance to hydrology, including soil disturbance from rutting. However, eastern prairie fringed orchid populations are so rare, the pollinators can’t seem to find the orchid flowers. prairie fringed orchid habitat, it could out- compete the western prairie fringed orchid; yet, non-selective control methods also pose a potential threat to the western prairie fringed orchid (U.S. This information is similar to that found in the Wildlife Action Plan for animals. Zettler, J.W. The glossary provides definitions for the abbreviations above. Surveys carried out to demonstrate no losses of populations and no net decrease in the number of plants at priority sites. Complete minimum viable population analyses. The recovery goal requires that populations of the Eastern Prairie Fringed-orchid be maintained throughout the species’ currently known Canadian range - that is, at all 21 sites where it is believed to be extant. A number of site-specific monitoring, management and planning initiatives have been undertaken across Ontario, although the monitoring protocol mentioned above has not necessarily been used for all projects since 2003. 1993. As previously mentioned, pollination of the Eastern Prairie Fringed-orchid depends on night-flying hawkmoths, which require large tracts of land containing a high diversity of sources of nectar (COSEWIC 2003). Figure 1. One or more action plans for the Eastern Prairie Fringed-orchid will be posted on the Species at Risk Public Registry by December 2017. A monitoring protocol has been developed for the Eastern Prairie Fringed-orchid in Ontario to assist monitoring of populations by using criteria that will allow trend-through-time and comparison analysis (Hunt 2003). The Eastern Prairie Fringed-orchid populations are sensitive to hydrological and successional changes. In Pennsylvania eastern prairie fringed-orchid is limited to a few clusters of sites in the glaciated portions of the northeast and northwest and a few scattered sites … Restoration of the eastern prairie fringed orchid (Platanthera leucophaea) by seed broadcast and management initiatives. Species at Risk Biologist, Midhurst District, Ministry of Natural Resources, Midhurst, Ontario. Both prairie and fen habitat continue to be lost in Ontario, mostly due to indirect and direct human impacts (COSEWIC 2003). Prepared for Walpole Island Heritage Centre, Environment Canada, and the Walpole Island Recovery Team. Plant Species Biology 17:37-49. In Canada, the Eastern Prairie Fringed-orchid is restricted to southern and eastern Ontario (NHIC 2007). 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. A Population Genetic Analysis of Platanthera leucophaea in Northeastern Illinois. Erigenia 11:52-66. Flowering occurs from late June to late July and proceeds sequentially along the flowering stalk, beginning at the base. The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. Several recovery techniques are being successfully applied to the Eastern Prairie Fringed-orchid populations in Canada and the United States, or, in some cases, to other closely-related species in the same genus. The status of most hawkmoth species in Ontario has not been evaluated. Evaluation should include the extent to which goals and objectives have been met. Chen, and H.F.

Location of the 16 extant populations of the Eastern Prairie Fringed-orchid in Ontario. 38 pp. 1999, Cuthrell et al. Although this trail is used mainly in the winter when orchids are dormant, people have also been observed using ATVs on this trail (S. Thompson pers. 2003. But here, in a tiny wet sedge meadow surrounded by farm fields in Clark County, the orchid is thriving. Species at Risk Act Recovery Strategy SeriesAdopted under Section 44 of SARA, Recovery Strategy for the Eastern Prairie Fringed-orchid (Platanthera leucophaea) in Canada – 2012. Ottawa. The extent and boundaries of the critical habitat within each location are defined by the extent of contiguous suitable habitat as described in Section 5.1.2, and will vary by location. Eventually, increased nutrient loads could transform these open fen habitats into closed cattail marshes, shrub fens or thicket swamps, excluding the Eastern Prairie Fringed-orchid. The Eastern prairie fringed orchid is generally found in open, sunny habitats dominated by herbaceous vegetation, where it occupies a broad moisture gradient. Management, such as prescribed burning, is required in late-successional prairie habitats to control the amount of encroaching woody vegetation (Bowles 1991). The results of the SEA are incorporated directly into the strategy itself, but are also summarized below in this statement. It is not known whether the increased depth of freezing that occurs when snow is compacted (e.g., by snowmobiles) has any impact on the species. Figure 1. The report contains a table outlining the specific actions and performance measures needed to reach these goals and objectives. American Midland Naturalist 145:168-175. The Eastern Prairie Fringed-orchid is currently found in fens, along fluctuating limestone shoreline and in wet mesic prairie and old field habitat. Critical habitat for the Eastern Prairie Fringed-orchid in Canada is partially identified in this recovery strategy to the extent possible based on available data. comm.

Conservation status rank: A rank assigned to a species or ecological community that primarily conveys the degree of rarity of the species or community at the global (G), national (N) or subnational (S) level. Role of pollinators: Pollination by night-flying hawkmoths is imperative to the long-term survival of Eastern Prairie Fringed-orchids. comm. 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. It has been found in wet and mesic prairies, wet meadows, sedge meadows, fens, and even bogs. Isolation and small population sizes may have a strong influence on reproduction of this species (Bowles et al. Unpublished report prepared for the U.S. This orchid is a perennial plant that grows from an underground tuber. Natural Areas Journal 3 (4):14-37. and willows. 2000). Ohio is home to a number of endangered plant species, including the rare eastern prairie fringed orchid. Searches were undertaken to locate the orchid at a site near Smith’s Falls where it was documented historically. 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.

Together, the addition and the provincial strategy (Appendix 3) apply to the Canadian population of the Eastern Prairie Fringed-orchid. 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. Eastern Prairie White Fringed Orchid (Platanthera leucophaea) Site Survey Report 2002, Ontario Ministry of Natural Resources Southcentral Region. 1999. ), Effectiveness of habitat protection measures. Additional habitat could be made available through restoration work for prairie and old field habitat types. Damage by recreational vehicles is known to have occurred at two sites at least. Influence of environmental factors and preliminary demographic analyses of a threatened orchid, Platanthera praeclara. comm. The eastern prairie fringed orchid grows in tall-grass calcareous silt loam or moist sand prairies. These are a work in progress, and we welcome your suggestions and feedback. At the Kent County site, the Eastern Prairie Fringed-orchid appears to respond positively to early spring burning (J. Haggeman pers. It produces 1-5 leaves along its stem and bears an inflorescence of up to 60 yellowish green or whitish flowers. Brownell, and G. Allen. Fish and Wildlife Service, Region 3, Minneapolis, Minnesota. It may not be possible to mitigate various threats to the species. comm. 149:104-120. Bruce Peninsula National Park. comm. Flooding caused by American Beaver (Castor canadensis) has been documented in the decline (at least in the short term) of a large population of the Eastern Prairie Fringed-orchid in Bruce County and is suspected in the loss of lakeside fen habitat in eastern Ontario. Environment Canada, Ottawa. The majority of extant populations occur in fen habitat; additional habitat of this type would be difficult to make available using habitat management and restoration techniques. Protection and recovery objectives, Table 3. and P.M. Catling. Unknown. 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. Therefore, the site occupancy criterion is defined as sites where the Eastern Prairie Fringed-orchid has been observed between 1990 and 2009. and Field Horsetail (Equisetum arvense). comm. It is likely possible to mitigate or avoid some threats to this species, including significant threats such as: further conversion to agriculture, trampling, collection and recreational vehicle damage. and goldenrods, along with the following secondary species: Sullivant's Milkweed, Bushy Aster (Symphyotrichum dumosum), Field Thistle (Cirsium discolour), Eastern Yellow Star Grass, Four-flowered Loosestrife, Riddell's Goldenrod, Stiff Goldenrod and numerous other prairie indicator species.
