United States Fish and Wildlife Service. Biologist, Manitoba Tall Grass Prairie Preserve, Manitoba. Individual plants in Minnesota monitoring plots have persisted for as long as 25 years, including reappearances after presumed dormancy (Sather and Anderson 2010). Brownell #84-89 (DAO)01 July 1985, P.M. Catling s.n. 22 pp. The last time a large burn occurred was approximately four years ago when there was a large wildfire. It is recommended that mowing activities occur after seed dispersal and that prescribed burns take place before orchids emerge or when orchids are dormant (North Dakota Parks and Recreation 2016). It most often grows in relatively undisturbed grassland, but can also occur in disturbed sites, such as ditches and pastures, if they are sufficiently stabilized and in a prairie-like condition (Sheviak 1974). Investigation of Western Prairie Fringed Orchidroot system showed varying degrees of infection by mycorrhizal fungi within the root cortex (Zelmer 1994). Today it is known from ten Minnesota counties scattered throughout the prairie regions of the state. 2015). National recovery plan for the western prairie fringed orchid, Platanthera praeclara. vi + 101 pp. 29 pp. There are only two other large subpopulations (Minnesota and North Dakota) in the northern Midwestern United States (Punter 2000). 2003). 2015). Orchids of Minnesota. American Journal of Botany 83:1050-1056. The population of Western Prairie Fringed Orchid in Manitoba is one of the largest in North America and the removal of a few plants or individual flowers from herbivores (without the destruction of the root system) is not likely to significantly harm the population (Borkowsky 2006). Federal Register, 75(177):55820-55823. Jordan, C.R., G.M. There is ongoing livestock farming on both private and public lands. University of Nebraska, Lincoln. In Manitoba, high years (totals >10,000 flowering individuals) occurred in 1996, 1997, 2003, 2004 and 2011 (Figure 5; Borkowsky pers. Minnesota State Climatology Office. 2015). 2013. 1986.

Historical collections from Douglas, Faribault, Freeborn, Fillmore, Goodhue, Hennepin, Houston, Kandiyohi, Martin, Nicollet, and Nobles counties are presumed to represent extirpated populations. 6) Pollution 9.0 (Agricultural & forestry effluents 9.3) - Calculated impact is Low. Land ownership is given in Table 3 (Hamel pers. 76 pp. Pleasants, J.M., and S. Moe. 2015). Before settlement, the prairie habitats of P. praeclara were exposed to wildfire at intervals of perhaps 2-4 years. pers. Committee on the Status of Endangered Wildlife in Canada. Conservation Genetics 17:69–76. Brownell #84-89 (MMMN)24 July 1985, K.L. Some of the seeds will germinate the following spring and a few might wait another year. Schultes, Moderate (Possibly in the short term, < 10 yrs/3 gen). Catling, P.M., and V.R. The Western Prairie Fringed Orchid west of Vita has been a catalyst for the acquisition of tall grass prairie land for incorporation into the Manitoba Tall Grass Prairie Preserve. Although it is believed that the seeds can be carried by wind, the closest subpopulation in the United States is approximately 50 km to the south in Lake Bronson State Park in Minnesota, and is quite small. praeclara, but Habenaria is now widely considered restricted to tropical species and Platanthera temperate zone species. Due to having a short reproductive time within the life cycle and an 80% chance of not persisting if a plant goes into dormancy, recruitment is very dependent on seed production (Sieg and Ring 1995; Borkowsky 2006). 1991. No germination was observed, but all packets contained viable seeds after that time period. 2015. They found evidence of significant but low levels of genetic divergence among subpopulations (mean GST=0.081), and some evidence of inbreeding (average FIS=0.230). comm.

The western prairie fringed-orchid (Platanthera praeclara): monitoring and research, p. 197–199 in: T. B. Bragg and J. Stubbendieck (eds.). Most germination of Platanthera seeds in the field probably takes place in the spring after seed dispersal (Rasmussen 1995), but it may extend throughout the year due to seed dormancy mechanisms, with germination being triggered by some environmental signal such as a period of low temperature (Gregg 1990, cited in Rasmussen 1995). Canadian Journal of Botany 73:1981-1985. High densities of flowering Western Prairie Fringed Orchid have been associated with high soil moisture content in the previous growing season (Sieg and Ring 1995). Edited by D.M. Fish and Wildlife Service, Twin Cities, Minnesota. 1993. Platanthera praeclara (Western Prairie Fringed Orchid) recovery plan. The overall threat impact was calculated as High-Medium. The most significant threats are ecosystem modifications that lead to habitat degradation and eventual loss and climate change. Synonyms: Habenaria leucophaea (Nutt.) Another new orchid: the prairie white fringed orchid (Platanthera leucophaea). Fish and Wildlife Service. Bowles, which is native to the midwestern USA, germinated in vitro only after they were exposed to 4- or 6-mo cold-moist stratification periods (Sharma et al. As with road allowances, the maintenance and herbicide use along utility lines is also an issue.

The Vita Drain, constructed in 1990 (Collicutt 1993), passing through the southern portion of the Rat River Swamp, connects Conroy Creek to the Roseau River near the village of Roseau River (20 km northwest of Vita). The ellipsoid capsules release thousands of microscopic seeds, which lack endosperm, through splits in the fruit (Bowles 1983). Fremont, J. C. 1845. The western prairie fringed orchid (Platanthera praeclara Sheviak and Bowles) is a threatened species of the tallgrass prairie. In a study of the natural pollination of 130 plants (1033 flowers), 33% of the available pollinia were removed by pollinators and fruit set was 30%. Department of Parks and Recreation, 6-9 August 1992, Windsor, Ontario, Canada. The community of Vita encroaches on eastern part of species range, although there doesn't appear to be any imminent plans for development (therefore, timing is moderate). Fish and Wildlife Service 1996; Punter 2000), there is a potential threat to pollinators on which the orchids are dependent (U.S. There are 2-5 alternate leaves along each stem, developing from sheaths. 2010). University of Minnesota Press, Minneapolis, Minnesota. It is ranked S1 in Manitoba, Kansas, Minnesota, Missouri, and SH in Oklahoma (NatureServe 2015; University of Oklahoma 2016). Is rescue from outside populations likely?

Within occupied sites, the number of flowering stems ranged from 1 to 2492 with the mean number of flowering individuals within a site ranging from 19 to 556 (Bleho et al. The number of flowering and vegetative plants decreased in successive years. North Dakota Parks and Recreation. Five years of following the Western Prairie Fringed Orchid (Platanthera praeclara) on the Sheyenne National Grassland, North Dakota. Possibly – one site has not been observed since 1998. Honey, J., and B. Oleson. Gray var. Mature orchids have endophytic mycorrhizal fungi in the cortical cells of roots or other absorptive structures (Currah et al. 2003. In the summer of 1988, ditch clearing destroyed 20 plants (Johnson 1989). Publ. 2001), in laboratory from seed have been successful in the United States. The EOO is < 5,000 km, Criterion C (Small and Declining Number of Mature Individuals). White-tailed Deer (Odocoileus virginianus) appear to graze the upper portions of Western Prairie Fringed Orchid(Punter 2000). Species at Risk Act Recovery Strategy Series. The pollinium protrudes from the moth’s head and pollen is transferred to the stigma when another flower is visited (Friesen and Westwood 2013). It is still currently unknown how feasible and successful reintroductions into the wild will be for Western Prairie Fringed Orchid because ex vitro survival of Eastern Prairie Fringed Orchid has been unsuccessful (Zettler and Piskin 2011). Fish and Wildlife Service. 3). In the Sheyenne National Grassland, North Dakota, flowers remain open for approximately seven days (Pleasants and Moe 1993) but elsewhere may last up to ten days; because flowers open sequentially, the inflorescence can produce flowers for up to three weeks (U.S. Pollinated at night by long-tongued hawkmoths. These conditions will have dramatic impacts on the prairie ecozones particularly in extreme southern Manitoba. The Manitoba government is working on effectively protecting these lands to restrict activities that would damage or destroy the critical habitat (as listed in the recovery strategy). It is one of only three sites with over 1000 individuals in North America. Since the early 1980s, the temperature has risen over 2°F in north Minnesota (adjacent to south Manitoba); the trend has been upward (Minnesota State Climatology Office 2015). Journal for Range Management 54(5):611-616. Seed germination and seedling development cannot progress without mycorrhizal fungi (Sharma et al. In Proceedings of the 7th North American Conference on Mycorrhizas. Native orchids of Minnesota. Wotton. This plan must assure implementation Ehrlich, W.A., E.A. As the species occurs within a very restricted range in Canada, it would be very vulnerable to environmental stochasticity (a random but extreme event that would affect all individuals in a location to a similar degree, such as a major flood, extreme drought, or disease outbreak). A layer of calcium carbonate accumulation is usually found within the till or between the till and sand layer. In Manitoba, the mode of seed dispersal is unconfirmed but both wind and water could be agents. Seeds are dust-like and wind dispersed. The sepals of P. praeclara are deflected downward behind the lip, and the lateral lobes of the lip are raggedly fringed almost to the base. Given the threatened status of the species, only up to ca. Fox, K., P. Vitt, K. Anderson. Designations are made on native species for the following taxonomic groups: mammals, birds, reptiles, amphibians, fishes, arthropods, molluscs, vascular plants, mosses, and lichens. Long-term cattle grazing may affect plants by trampling or herbivory. Bulletin 123. Cattle grazing reduces survival and reproduction of the Western Prairie Fringed-Orchid. Center for Plant Conservation plant profile page for Platanthera praeclara. Fire should be limited after the orchids have emerged (as early as late March in southwestern Minnesota and early April in northwestern Minnesota). New Phytologist 65:488-499. COSEWIC. Populations on the edges of a species’ range are more vulnerable to extinction due to diversity-related factors than those at the core (Environment Canada 2006). (Buthod and Fagan pers. 1992). This image may not be reproduced separately from this document without permission of the photographer. Whether or not this is indicative of a decline in population or just unfavourable conditions for flowering is uncertain. The species is apparently extirpated from South Dakota (U.S. Seeds are key to producing the next generation of plants, which provide food for the next generation of pollinators and other wildlife. Although nectar is a favourable reward for pollinators it also attracts nectar robbers, which chew holes in the nectar spur, and nectar thieves, that avoid assisting in pollination while stealing nectar (Fox et al. Please message me. The threats calculator indicates a high-low overall threat impact. 2014. in Punter 2000). 1983. Oklahoma Natural Heritage Inventory Plant Ranking List (PDF Version; 223 KB). praeclara (Sheviak & Bowles) Cronq., Cronquist, ed. Platanthera praeclara, western white-fringed orchid. Platanthera praeclara seeds placed in. Soils within the Garson Soil Complex are non-arable due to excessive stoniness (Ehrlich et al. Sheviak, C.J., and M.L. Fox, K., P. Vitt, K. Anderson, G.

However, only subpopulations with fewer than 10 flowering individuals had FIS>0.2. Is there an [observed, inferred, or projected] decline in extent of occurrence? Platanthera is easily propagated on sterile media and is grown like Dactylorhiza. (2014) consider late spring burns to be harmful as the greatest fire susceptibility occurs during periods of rapid growth. Likewise, in the Sheyenne National Grassland, tagged plants were absent in subsequent years (Sieg and Ring 1995). Off-road vehicles are also known from the area; plants in ditches may also be affected by all-terrain vehicles (ATVs). 2006. Department of Northern Affairs and National Resources, Forestry Branch. With 33 species, Platanthera is the largest genus of orchids found in North America In the northern part of the species' range, known pollinators include the Galium Sphinx (Hyles gallii), the Wild Cherry Sphinx Moth (Sphinx drupiferarum), the Achemon Sphinx (Eumorpha achemon) and the non-native Leafy Spurge Hawkmoth (Hyles euphorbiae) (Fox et al. Credit Union Central of Manitoba. Prairie Naturalist 42:46-49. 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. Western Prairie Fringed Orchid is a herbaceous perennial. in Punter 2000). 2003).
