Contingent on the above findings, assess threats and site conditions to determine the feasibility (or need) of augmenting populations in natural settings at extant locations. The species is noted for its ability to persist (Zaya and Howe 2009) but roadside and fencerow trees have limited long-term viability and few chances to repopulate natural habitat (COSEWIC 2000). Gymnocladus dioicus. 2007. Double-crested Cormorant (Phalocrocorax auritus) populations in the Great Lakes underwent dramatic declines throughout the 1960s and into the 1970s due predominantly to toxic contaminants affecting reproductive success (Weseloh and Collier 2005). Committee on the Status of Endangered Wildlife in Canada. comm. Reproductive biology of rare Carolinian plants with regard to conservation management. Acknowledgement and thanks is given to all other parties that provided advice and input used to help inform the development of this recovery strategy including various Aboriginal organizations and individuals, individual citizens, and stakeholders who provided input and/or participated in consultation meetings. Although Dog-strangling Vine infestation would likely not kill existing trees, by competing for habitat this species could prevent seedling establishment and expansion of populations to new sites. The global conservation rank for Kentucky Coffee-tree (Gymnocladus dioicus) is secure[1] (G5). These habitats are often susceptible to seasonal flooding, which inhibits canopy closure by competing tree species. Essex Forests and Wetlands Conservation Action Plan (CAP). Particularly susceptible are edge trees; many occurrences of Kentucky Coffee-tree in Ontario consist of trees found along edge habitats. The increase in the number of nesting cormorants since the 1980s has led to a corresponding increase in the damage and subsequent death of trees on Middle Island and East Sister Island, including mature Kentucky Coffee-trees (Hebert et al. 1959. 9Place or source of origin. Given that the current primary regeneration strategy is by ramets, expansion of a population will occur within the vicinity of the ‘parent’ tree as ramets originate from existing roots. iv + 68 pp. In Ontario, Kentucky Coffee-tree is listed as Threatened[5] under the provincial Endangered Species Act, 2007 (ESA). This may cause local extirpation of Kentucky Coffee-tree by preventing seedling establishment, due to lack of solar radiation on the forest floor required for seed germination (White and Oldham 2000). COSEWIC. 1995. (Fabaceae) dioicus K. Koch. Hebert, C.E., J.A. Technical Bulletin 1879. Copublished by Fitzhenry and Whiteside Limited, Markham, ON. To respect provincial data-sharing agreements, as well as best practices for reducing further risks to the species and its habitat, locational information is presented as 1 × 1 km UTM grids (Table 3). Single-sex populations currently occurring within natural settings (e.g., floodplain woodlands and woodland edges of marshes) will be augmented with both opposite-sex and same-sex individuals as these populations contain the suitable habitat necessary to allow for expansion of the population once sexual reproduction is achieved. Personal communication by email with E. Followes, October 2007. As a result, it can be difficult to ascertain whether trees are: native, planted from native stock, planted cultivars from the United States, or offspring of horticultural specimens that have spread into natural habitat. 4The area presented is that of the site boundary (rounded up to the nearest 1 ha); an approximation based on a maximum extent that may contain critical habitat within the grid square. Gymnocladus dioicus Figure 1. Également disponible en français sous le titre « Programme de rétablissement du chicot févier (Gymnocladus dioicus) au Canada ». pp. The Board of Trustees of the Royal Botanic Gardens, Kew. Site Occupancy Criterion: A site is considered occupied when a native Kentucky Coffee-tree has been observed between 1992 and 2011 in suitable habitat. Critical habitat is the suitable habitat (Section 7.1.1) within a 20 m radial distance of extant native Kentucky Coffee-trees, observed between 1992 and 2011, occurring in natural settings. Implementation of this strategy is subject to appropriations, priorities, and budgetary constraints of the participating jurisdictions and organizations. Special plant abstract for Gymnocladus dioicus (Kentucky Coffee-tree). Personal communication by email with K. Hayes, January 2007. 291 pp. The wood from the tree is used by cabinetmakers and carpenters.It is planted as a street tree. lobata), native to Asia, is an aggressive vine that is able to climb over top of trees and saplings, smothering them and eventually leading to death (Berisford et al. Drought and pollution tolerant. Baskin. The information and objectives presented in this recovery strategy pertain to the 23 recognized native extant populations of Kentucky Coffee-tree in Canada. 31 pp. From Wikimedia Commons, the free media repository.

Two sub-populations along river: one male clone of ~ 95 trees and sapling-sized ramets; one female clone of 5 trees and a sapling. What it looks like. Conservation Biologist, Essex Region Conservation Authority, Essex, Ontario. Broad strategies to be taken to address the threats to the survival and recovery of the species are presented in the section on Strategic Direction for Recovery (Section 6.2). [accessed: December 2010]. comm. Related Plants 'Stately Manor' 'Variegata' The word dioicus relates to dioecious, meaning there are male and female trees. Under the Species at Risk Act (S.C. 2002, c.29) (SARA), the federal competent ministers are responsible for the preparation of recovery strategies for listed Extirpated, Endangered, and Threatened species and are required to report on progress within five years. The predatory fish species were declining in part because of years of heavy fishing, the invasion of the Sea Lamprey (Petromyzon marinus) and the loss of spawning areas (Weseloh and Collier 2005). Gymnocladus dioica is a deciduous Tree growing to 20 m (65ft) by 15 m (49ft) at a slow rate. In keeping with the precautionary principle, a full recovery strategy has been prepared as per section 41(1) of SARA, as would be done when recovery is determined to be feasible. 6Ramets are genetically identical individuals (i.e., clones) of a plant that has spread vegetatively (i.e., not through sexual reproduction). The critical root radius is used to define a zone surrounding the tree to prevent damage or disturbance (such as soil compaction) to the roots, dripline[13] and soil. gymnocladus diocus synonyms, gymnocladus diocus pronunciation, gymnocladus diocus translation, English dictionary definition of gymnocladus diocus. Researcher, recovery team member, Curator of the Sherwood Fox Arboretum, University of Western Ontario, London, Ontario. *Threat categories are listed in approximate order of decreasing significance based on existing information and knowledge. Carey. A correlation exists between current extant stands of Kentucky Coffee-tree and former Native American and Aboriginal settlements; thus, it is possible to infer that these cultures played a significant role in the perpetuation of the species and in shaping the tree’s current distribution (VanNatta 2009). The possibility of pollination between single-sex clones separated by several hundred metres, upwards to approximately 500 metres, is possible (Ambrose and Kevan 1990). Kentucky coffeetree has the largest leaf of any native tree, up to 90 cm long, but it is doubly compound, and leaflets are small and oval. NHIC (Natural Heritage Information Centre). Researcher, recovery team member, Curator of the Sherwood Fox Arboretum, University of Western Ontario, London, Ontario. Short Hills Conservation Action Planning Team and the Carolinian Canada Coalition. Populations on the Lake Erie Islands are usually in shallow-soiled open Common Hackberry-dominated limestone woodland (COSEWIC 2000). 2012. 1980. In Ontario, the species typically grows in rich floodplain woodlands and woodland edges of marshes where open canopy conditions exist (COSEWIC 2000). Slow to moderate growth rate. Threatened and Endangered Information: This plant is listed by the U.S. federal government or a state. 2008. comm. 3 pp. 2009. It is native to the Midwest, primarily southern Michigan and Ohio southwest to Iowa, Kansas, Oklahoma and Arkansas. XIV International Botanic Congress, Berlin (poster). 2001. The UTM grid is a standardized national grid system that indicates the general geographical area containing critical habitat and can be used to highlight areas that contain critical habitat (e.g., by land-use planners, landowners, or during an environmental assessment).

However, it is recognized that strategies may also inadvertently lead to environmental effects beyond the intended benefits. Species at Risk Act Policy and Guidelines Series. Personal communication to Environment Canada – Canadian Wildlife Service via B. Walpole. Environment Canada, Canadian Wildlife Service – Ontario Region. Although this equates primarily to natural vegetation types (e.g., swamp, marsh, forest, woodland, prairie and savannah), as described by the Ecological Land Classification (Lee et al. Lake Erie LaMP. Greenish-white flowers in terminal clusters appear in May and June, and expand after the new leaves emerge, with male and female flowers generally produced on separate trees. Some occurrences on Walpole Island First Nation are known to be found near former Anishnaabeg homesteads (Jacobs pers. Hardiness zones are based largely on climate, particularly minimum temperatures. Pronunciation of gymnocladus dioicus with 1 audio pronunciation, 1 meaning, 1 translation and more for gymnocladus dioicus. You will not receive a reply. Kentucky Coffee-tree is frequently planted as an ornamental tree, often from non-native stock originating in the United States. Population locations and extent of surrounding suitable habitat are required to delineate additional critical habitat. With that being said, there is some indication that suitable habitat still exists at historic locations that have not been visited for many years (pre-1991) and that populations at these locations may remain extant. Based on this and until additional information is available, the suitable habitat within a 20 m radial distance is thought to be sufficient to allow for the establishment and growth of ramets. 38 pp. 2000. 3Causal certainty: reflects the degree of evidence that is known for the threat (High: available evidence strongly links the threat to stresses on population viability; Medium: there is a correlation between the threat and population viability e.g. 57-63. in G.M. Kentucky Coffee-tree appears to be associated more with site conditions (e.g., open canopy) than with specific species compositions. People and Plants in Ancient Eastern North America. This distance is generally used in recognizing separate occurrences/populations in the COSEWIC, NatureServe and the Ontario Natural Heritage Information Centre records for immobile and/or vascular plants. Gymnocladus dioicus. VanNatta, A.R. It bears greenish-white fragrant flowers in the spring but does not develop the dark brown seed pods that the female trees bear. Forest succession along the flood gradient is strongly influenced by the long-term flow regime or average annual flood pattern, as well as unusual hydrologic events such as extreme droughts and floods that are not seasonal or predictable (Yin et al.1994). At extant sites characterize habitat, assess threats and investigate reproductive status. In Canada, Kentucky Coffee-tree occurs at the northern extent of its North American range; extreme southwestern Ontario. Gymnocladus dioicus) is listed as threatened on the SARO List. Destruction would result if part of the critical habitat was degraded, either permanently or temporarily, such that it would not serve its function when needed by the species. 1980. Comments: A rather slow-growing, deciduous tree attaining 60' tall by 20-30' wide. On the other hand, Bowles (pers. Although it prefers moist rich soils it is highly adaptable to poor soils, and acidity making it a suitable tree for urban environments and streets. Carpinus caroliniana. 3A value of "0" means the grid contains a portion of (a) critical habitat site(s) but not the site centroid. 2The listed coordinates are a cartographic representation of where critical habitat can be found, presented as the southwest corner of the 1 × 1 km standardized UTM grid containing all or a portion of the site containing critical habitat. Stout twigs are adorned with massive bipinnately compound leaves that can reach as much as 3' in length. Recent site visits (as of December 2011) indicate that fruit-bearing trees were present at the Shetland Kentucky Coffee-tree Woods - Zone Township population and the Petrolia - Enniskillen Township population; due to the timing of these surveys (i.e., winter), spring or summer site visits to confirm reproductive status are required.

Conduct outreach and/or educational activities with key audiences to encourage conservation and protection of the tree and its habitat. Critical habitat for Kentucky Coffee-tree is located on both federal and non-federal land. This plant has no children Legal Status. Removal of trees has occurred more recently at some populations on private land; in at least one instance, this reduced the population to a single-sex occurrence (see Appendix C). Critical habitat for Kentucky Coffee-tree is partially identified in this recovery strategy, based on the best available data. Gymnocladus dioicus: Kentucky Coffeetree 1. USDA (United States Department of Agriculture). Threats identified to the Canadian population of Kentucky Coffee-tree include, but are not limited to: land development, Double-crested Cormorant (Phalocrocorax auritus) nesting colonies, alteration of the water regime, alteration of the fire regime, cutting/removal of Kentucky Coffee-trees, planting of non-native Kentucky Coffee-trees and invasive species. 5A species that lives in the wild in Ontario but is likely to become endangered if steps are not taken to address factors threatening to lead to its extinction or extirpation. 2006. Kentucky Coffee-tree seeds are unable to germinate in shaded conditions. Many planted trees across southern Ontario are of unknown genetic origin and some occur well beyond the species known native range (e.g., Toronto, Hamilton and Ottawa). Gymnocladus dioicus . Personal communication with R. DeCatanzaro, July 2011. 2011). Apparently dead, standing snags are included because ramets are often observed in the vicinity of individuals which otherwise appear to be dead. *COSEWIC = Committee on the Status of Endangered Wildlife in Canada.

Natural Heritage Ecologist, Chatham Area Office, Ontario Ministry of Natural Resources, Chatham, Ontario. Kentucky Coffee-tree (Gymnocladus dioicus) is a moderate-sized canopy tree of the legume family, and is the only member of its genus in North America. 2011. 2002. Mature trees grow 18 to 30 m tall (USDA 2007) and may live up to 100 years or more. Extant native populations in landscaped or agricultural settings have been maintained. 2001). Kozlowski, T.T. Kentucky Coffee-tree has a short growing period relative to other deciduous trees (Kozlowski and Ward 1957), with the leaves developing late in the spring and falling in early autumn; it is therefore leafless for half the year or more. maintain the remaining extant native populations that occur in landscaped or agricultural settings either in situ or through their incorporation into, or use in the establishment of, populations in natural settings. Integrate restoration planning and activities with partner agencies and groups such as conservation authorities and other non-governmental organizations, First Nations and federal and provincial government agencies. 2007. 2005; Hebert pers. Jacobs (pers. One study found that Kentucky Coffee-tree is one of the most vulnerable tree species to heavy flooding of rivers (Yin et al. 2001. A hardiness zone is a geographically defined area where a given plant is capable of growing. Gymnocladus dioicus is a species of tree in the genus Gymnocladus of the legume family. Species at Risk Act Recovery Strategy Series. . Ottawa, ON. This has likely contributed to the increase of saplings observed on East Sister Island and may continue to stimulate vegetative reproduction on these islands (Dobbyn pers. Given that in Canada the species is found at the northern extent of its North American range and is uncommon, it will likely always be vulnerable to natural and human-influenced stressors. NatureServe, Arlington, Virginia. Payne, T. pers. While roadside populations are at risk of eradication by right-of-way maintenance they likely include important genetic diversity in addition to that found in the very few sexually-reproducing populations. In addition, there is evidence that the germination of Kentucky Coffee-tree seeds can be stimulated by fire with the species sometimes found in large numbers in burned-over areas (Minnis 2005; Garren 1943; Horr 1927). Seeds that were observed to have washed downstream from one population in the Sydenham River did not germinate successfully, despite seemingly appropriate habitat and light conditions (Craig pers. The species has stout, widely-spaced branches and a narrow crown, with large, doubly-compound leaves that can reach one metre in length, the longest of any tree in Canada. *Rank refers to the Natural Heritage Information Centre quality ranks based on the estimated viability or probability of persistence of the occurrence: A – Excellent, B – Good, C – Fair, D – Probably not viable, E – Verified extant, H – Historical, X – Extirpated and ? Committee on the Status of Endangered Wildlife in Canada. 13The area beneath a tree defined by the outermost circumference of the tree’s canopy where water drips from the tree’s foliage onto the ground. COSEWIC Status History: Designated Threatened in April 1983. Introduction. The 20-year window is consistent with the NatureServe (2011) and Ontario’s Natural Heritage Information Centre (NHIC) (2010) threshold for considering populations to be extant versus historic, and allows for inclusion of a number of native populations that likely persist but which have not been recently surveyed. Of particular concern are the two species of Dog-strangling Vine (Cynanchum rossicum and C. louiseae), which are allelopaths, emitting chemicals that inhibit or prevent growth of other plant species. Japanese Wisteria. A summary of research findings. Ecologist, Ontario Parks SW Zone. This results in infrequent germination and probably accounts for the fact that the species is rare or uncommon throughout much of its extensive North American range (Yeiser 1983; Ball and Kisor 1985). Although critical habitat will not be identified for extant native populations, or sites within an extant native population, occurring in landscaped or agricultural settings, these trees may contain important genetic material for recovery and, depending on where they occur, are either protected under the prohibitions listed in the Species at Risk Act (on federal lands) or the Endangered Species Act, 2007 (on non-federal lands). Ambrose, J.D. Zaya and Howe 2009 support this and hypothesize that the entire life cycle of Kentucky Coffee-tree is a relic of processes and environments driven by extinct large mammals. 1995. One of the main limiting factors for Kentucky Coffee-tree is the lack of reproduction by seed. comm. 2007). Success in the recovery of this species depends on the commitment and cooperation of many different constituencies that will be involved in implementing the directions set out in this strategy and will not be achieved by Environment Canada or the Parks Canada Agency, or any other jurisdiction alone. 8Diameter at breast height (dbh) - a standard method of expressing the diameter of the trunk of a tree taken at 1.3 m above ground level. Gymnocladus dioicus; Media in category "Gymnocladus dioicus" The following 46 files are in this category, out of 46 total. Many Kentucky Coffee-tree stands have undoubtedly been lost over the decades through development (e.g., urbanization, industrial, road and agricultural), and a number of local extirpations have been confirmed (Appendix C). (ed.). COSEWIC status report on the Kentucky coffee-tree, Gymnocladus dioica in Canada. Recovery planning is intended to benefit species at risk and biodiversity in general. ISBN Catalogue no. Field verification may be required to determine the precise area of critical habitat. ERCA (Essex Region Conservation Authority). Kentucky Coffee-tree (Gymnocladus dioicus) is a moderate-sized canopy tree of the legume family, and is the only member of its genus in North America. Critical habitat is currently not identified for the Walpole Island First Nation populations or the Sydenham River, Florence, Euphemia Township population. – Rank or status uncertain. 2008. 23 pp. The Biota of North America Program (BONAP) North American Plant Atlas. Flower: Species is dioecious; males and females in long (3 to 4 inch) branched clusters, whitish, appearing in late spring. Height: 60 - 100 feet. Ontario Parks is preparing a background document that summarizes a number of studies to investigate the overall effects of cormorants on the island ecosystem (Dobbyn, A cooperative restoration program involving Walpole Island First Nation and the Sherwood Fox Arboretum of the University of Western Ontario (UWO) has been established to restore or increase native populations at priority locations such as Walpole Island First Nation (Jacobs, The University of Guelph Arboretum has a living gene bank of many of the Ontario populations of Kentucky Coffee-tree collected in the mid 1980s (Ambrose, The largest confirmed sexually-reproducing population, the Canard River Floodplain – Anderdon Township population, occurs on public land (Canard Valley Conservation Area owned by the Essex Region Conservation Authority); the site was identified for the focus of habitat restoration activities, as part of a larger Biodiversity Conservation Strategy (, Various conservation documents and conservation action plans (, Walpole Island First Nation is currently developing an ecosystem protection plan based on the community’s traditional ecological knowledge (, Mitigation, in response to Kentucky Coffee-tree removal at a subdivision developed in Ancaster, Ontario, involved the establishment of mixed-gender population(s) in Essex through strategic planting and site restoration (Pickett. Kentucky Coffee-tree populations in Canada are limited by low rates of sexual reproduction. Taylor Jr. 2006. The Minister of the Environment and the Minister responsible for the Parks Canada Agency are the competent ministers for the recovery of the Kentucky Coffee-tree and have prepared this strategy, as per section 37 of SARA.

Biodiversity Explorer: Species Lists, Element Occurrence and Natural Areas databases. It has been introduced widely as an ornamental plant, from Texas to Quebec and in the states of northern New England. OMNR (Ontario Ministry of Natural Resources). Based on currently available information, 15 of the 23 extant native populations of Kentucky Coffee-tree in Canada occur within natural settings[12] (e.g., floodplain woodlands and woodland edges of marshes), with an additional six in landscaped or agricultural settings (e.g., agricultural fields, roadside ditches, lawns and fencerows) and two within undetermined settings (Appendix C). and M.J. Oldham. Woodland Species at Risk Inventory in the St. Clair Region Conservation Authority. In Canada, it occurs only in extreme southern Ontario, in Middlesex, Essex, Kent, and Lambton Counties (Figure 2). Wilson and R.A. Jones. and H.F. Howe. The coordinates may not fall within critical habitat and are provided as a general location only. comm. The identification of critical habitat for Kentucky Coffee-tree is based on habitat suitability and site occupancy by Kentucky Coffee-tree. 2007. This is a medium-growing tree that will reach a height of about 70 feet while spreading 45 to 60 feet. Wildlife Section. 1-11 pp. Drains, dams and other flood control measures upriver from floodplain occurrences can threaten Kentucky Coffee-tree populations occurring in this habitat type. Pridham, D. and M. Irvine. Personal communications with J. Jalava, January 2011. Critical habitat for Kentucky Coffee-tree is identified in this recovery strategy as the suitable habitat (Section 7.1.1) within the site boundary as per the Site Occupancy Criterion (Section 7.1.2). Kentucky Coffee-tree grows best on fertile loam soil with ample moisture, and tolerates alkaline soils and dry sandy soils. Gymnocladus dioica (L.) K.Koch is an accepted name This name is the accepted name of a species in the genus Gymnocladus (family Leguminosae ). and B. Collier.

Species At Risk Biologist, Ontario Ministry of Natural Resources, Guelph District, Guelph, Ontario. Male and female flowers are generally produced on separate trees and, when fertilized, form a hard, dark, bean-like … Reduced toxin levels in the Great Lakes are unlikely the sole factor responsible for the increase in cormorant numbers (Weseloh and Collier 2005). Stems are very stout and well-spaced, resulting in a coarse winter texture. It is hypothesized that many of the floodplain populations of Kentucky Coffee-tree occurring in North America originated from abandoned human settlements of Native Americans, Aboriginal peoples and early European pioneers where the seeds were used as game pieces and as a coffee substitute (after roasting to detoxify) (Curtis 1959; McClain and Jackson 1980; Zaya and Howe 2009). , easy to germinate more Action plans for Kentucky Coffee-tree is based on existing information objectives...
