Burning Bush (Euonymus Alatus) Watch Protocol Burning Bush (Euonymus alatus) Watch Protocol United States Executive Order 13112 defines an invasive species as “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health.” Invasives have huge impacts, both economically and environmentally. It is estimated that invasive species cost the United State more than $120 billion in damages every year (Pimental et al. 2005)! Most of this cost comes from prevention, detection, rapid response, outreach, and habitat restoration. These invasives cause large-scale environmental impacts in agricultural operations, native fisheries, tourism, outdoor recreation, and the overall health of ecosystems. Invasives alter predation regimes and pressures, degrade the structure of habitats, and compete with native species for resources. Invasive plant species, in particular, are adaptable, have aggressive growth, and have a high reproductive capacity. These characteristics combined with a lack of natural enemies often leads to outbreak populations. A lot of information is needed to investigate a plant as a potential invasive species including its invasion status (does is maintain populations outside of captivity; where is it located), biological characteristics (does it produce seeds with a high germination rate; does is spread vegetatively), and ecological impacts (does it harm other associated plants or animals). Once a species is listed as invasive, law-makers can use this information to create laws to protect our native ecosystems from these plants! Burning bush (Euonymus alatus) is a very popular ornamental shrub native to Asia that is of growing concern as an invasive species in Ohio. A small amount of information is known about the potentially invasive biological characteristics of burning bush (it produces a high number of seeds, the seed germination rate is high, and it spreads vegetatively through root sprouting). There is no current knowledge of the ecological impacts of burning bush on the forest environment; but researchers at Wright State University are beginning to investigate these impacts. Burning bush has begun to establish populations outside of planted areas; however, its specific invasive status is unknown. In order to most accurately examine the extent of burning bush invasion, the location and extent of the invasion must be carefully documented. However, because burning bush invasion may be widespread, the researchers are asking for the help of the master naturalists! While out on hikes, camping trips, driving, or any other outdoor experience, please look for burning bush! Tips for identifying burning bush and the documentation protocol are below. Thank you in advance for your participation and help! [email protected] Burning Bush (Euonymus alatus) Identification: Burning bush is a deciduous shrub that grows up to 8 ft. tall. The leaves are broad and diamond shaped with a rounded tip. They are 2-7cm in length and 1-4cm wide. The stems of burning bush have a characteristic “winged” appearance, although the “wings” may be less pronounced in shaded individuals. This characteristic leads to the two common names for this plant, “winged-burning bush” and “winged wahoo”. The most striking characteristic of burning bush is its striking red fall color, which remains after many other species have lost foliage. This makes it very easy to identify during the fall. During this time, the plant also has orange-red fruits. Burning Bush Reporting Protocol: 1. Print out the Burning Bush Watch Data Sheet 2. Use the burning bush identification guide to locate the shrub. 3. Record the observation number (you may find more than one burning bush location on a given observation day) 4. Take and record GPS coordinates of the burning bush on the data sheet. a. This is very easy using the Google Maps App on Android or iPhone! i. Open the app. ii. Just press and hold your location on the map. iii. On the bottom of your screen, tap the white area that says “Dropped Pin.” iv. Record the GPS Coordinates on the data sheet. b. If you do not have a smart phone or GPS unit, just record the location of the shrub in detail on the data sheet. i. For example: “Taylorsville MetroPark – one mile north on the orange trail from parking lot CC; on right side of trail approx. 10m off trail” 5. Record a few brief notes about the invaded area: open or forested? Dominant plant species? Flat ground or on hill? 6. Classify the proximity to currently occupied homes or yards/abandoned homesteads where burning bush may have been planted (A = no homestead noted; B = homestead < 10m away; C = homestead < 50m away; D = homestead < 100m away) 7. Estimate and record the height/ average height of the plant/plants. a. It is easy to use your body to help predict height. For example, in the picture below, the shrub is as tall as my mid-thigh. I would estimate the height to be 2ft. 8. Estimate and record the area of land covered by the shrub/shrubs. a. For example, in the picture above, I would estimate the area covered to be 1ft2. 9. Fill in the electronic data sheet with the data you collected. 10. Email the completed data sheet to [email protected] 11. Thank you so much for your help with this project! Please feel free to email with any questions. .

    Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only

  • Guide to the Euonymus of New York City
    New York City EcoFlora Guide to the Euonymus (Euonymus) of New York City Euonymus is a genus of 130–140 species in the mostly tropical Celastraceae (Staff-Tree) family. The family comprises about 95 genera and 1,350 species. Only three genera occur in the northern hemisphere, Euonymus, Celastrus and Parnassia, all three found or once found in New York City. Euonymus species occur nearly worldwide with most species native to eastern Asia. They are trees, shrubs or woody vines, the stems often angled or winged, sometimes climbing by adventitious roots; leaves deciduous or evergreen, opposite, the blades simple, margins crenate or toothed; inflorescences terminal or axillary; flowers in small clusters, petals usually green, sometimes white or purple; fruit usually brightly colored, lobed capsules; seeds enveloped in brightly colored tissue (aril), often contrasting with the fruit wall. Euonymus (as well as most members of the Celastraceae family) can often be recognized by “gestalt”. The leaves and often the stems too have a distinctive, but somewhat variable yellow-green color that is hard to describe but nearly unlike any other plants. The leaves are usually leathery, and almost always have distinctively scalloped (crenate) margins (the margins rarely completely smooth or toothed). There are four species native to North America, one species endemic to California, Oregon and Washington (Euonymus occidentalis); a predominately Midwestern species (Euonymus obovatus); a widespread northeastern species (Euonymus atropurpureus) and a widespread southeastern species (Euonymus americanus). Two species are indigenous to New York City. The predominately southeastern US species, Euonymus americanus, American Strawberry Bush is endangered in New York State.

Key words: conservation status, endangered, Euonymus, lectotypification, taxonomic revision Introduction Euonymus Linnaeus (1753: 197) is one of the largest genera of Celastraceae, with about 130 species worldwide (Blakelock 1951, Ma 2001). Five sections are currently recognized based on fruit characters. Ninety five species from all five sections occur in China (Cheng et al. 1999, Ma 2001, Ma & Funston 2008). Due to limited field observations, specimens in herbaria and insufficient knowledge of critical morphological characters of flowers and/or fruits, some taxonomic problems remain unresolved. Species in limestone areas in China have especially narrow distributions and are represented by few collections only.

Joan XXIII s/n, E-08028, Barcelona, Catalonia, Spain. Author for correspondence (E-mail: [email protected]) Zhao, A-Man Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, The People’s Republic of China. Manuscript received in april 2004 Abstract China is one of the richest countries in plant biodiversity in the world. Besides to a rich flora, which contains about 33 000 vascular plants (being 30 000 of these angiosperms, 250 gymnosperms, and 2 600 pteridophytes), there is a extraordinary ecosystem diversity. In addition, China also contains a large pool of both wild and cultivated germplasm; one of the eight original centers of crop plants in the world was located there. China is also con- sidered one of the main centers of origin and diversification for seed plants on Earth, and it is specially profuse in phylogenetically primitive taxa and/or paleoendemics due to the glaciation refuge role played by this area in the Quaternary. The collision of Indian sub- continent enriched significantly the Chinese flora and produced the formation of many neoen- demisms. However, the distribution of the flora is uneven, and some local floristic hotspots can be found across China, such as Yunnan, Sichuan and Taiwan. Unfortunately, threats to this biodiversity are huge and have increased substantially in the last 50 years.

Box 705 Cedar Key, Florida 32625 [email protected] ABSTRACT Euonymus japonicus Thunb. is reported here as new to the Arkansas flora. This is the first definitive record of this species outside of cultivation in Arkansas. One spontaneous plant of E. japonicus was discovered growing at the edge of disturbed, urban woods in Clark County. Photographs of the plant in habitat are provided. In 2017, a single, spontaneous/escaped plant of Euonymus japonicus Thunb. (Japanese spindle tree) was documented at the edge of a large expanse of highly disturbed, urban woods in Clark County (Figs. 1–2). The site, although large, is surrounded mostly by residential areas, with Rose Hill Cemetery about one block northeast of the location. No cultivated plants of E. japonicus were in the immediate vicinity, but a large, cultivated plant of E. japonicus is present in the Rose Hill Cemetery. Bird–mediated dispersal of seeds from the cultivated plant of E. japonicus is the presumed source of the spontaneous E. japonicus individual . Escaped E. japonicus should be expected elsewhere in Arkansas, particularly in the vicinity of where plants of the species are cultivated.
