APPROVED PLANT LIST Midtown Alliance Tree Well Adoption Program
APPROVED PLANT LIST Midtown Alliance Tree Well Adoption Program Midtown Alliance launched the Tree Well Adoption program with the primary goal of enriching the experience of Midtown’s workers and residents while encouraging sustainability through the use of low-water, urban tolerant plant species. This list of plants was created to aid individuals and organizations in selecting plant material to plant in their adopted tree wells. This plant list is intended to encourage individual character in the tree wells, rather than restrict creativity in the selection of plants. The plants on the approved list were selected based on the following criteria: • Perennial. All plants listed are perennial, meaning they last for two or more growing seasons. Once established, these plants will require less water to maintain than annuals. • Heat tolerant. Plants in tree wells are exposed to high temperatures caused by vehicles and heat reflected from surrounding buildings, asphalt, and other urban surfaces. They must also be tolerant to high daytime temperatures, typical of Atlanta’s summer months, and cold hardy in the winter months. Atlanta is located in USDA Plant Hardiness Zone 7b/8a. • Water wise. Urban tree wells are surrounded by impervious surfaces and thus, are highly susceptible to periods of drought. Suitable plants must be able to survive periods of low rainfall. • Pollution tolerant. Vehicle exhaust may leave deposits and pollutants on plant foliage, which can kill sensitive plants. • Encourage wildlife. Flowering plants attract insects such as butterflies while others provide food sources for birds and other wildlife. • Grown locally. Many of the plants listed are native to the Atlanta area, and all can be found at local nurseries.

The mpI ortance of Geographic and Biological Variables in Predicting the Naturalization of Non-Native Woody Plants in the Upper Midwest Abstract The es lection, introduction, and cultivation of non-native woody plants beyond their native ranges can have great benefits, but also unintended consequences. Among these consequences is the tendency for some species to naturalize and become invasive pests in new environments to which they were introduced. In lieu of lengthy and costly field trials, risk-assessment models can be used to predict the likelihood of naturalization.

Wa Shan – Emei Shan, a Further Comparison
photograph © Zhang Lin A rare view of Wa Shan almost minus its shroud of mist, viewed from the Abies fabri forested slopes of Emei Shan. At its far left the mist-filled Dadu River gorge drops to 500-600m. To its right the 3048m high peak of Mao Kou Shan climbed by Ernest Wilson on 3 July 1903. “As seen from the top of Mount Omei, it resembles a huge Noah’s Ark, broadside on, perched high up amongst the clouds” (Wilson 1913, describing Wa Shan floating in the proverbial ‘sea of clouds’). Wa Shan – Emei Shan, a further comparison CHRIS CALLAGHAN of the Australian Bicentennial Arboretum 72 updates his woody plants comparison of Wa Shan and its sister mountain, World Heritage-listed Emei Shan, finding Wa Shan to be deserving of recognition as one of the planet’s top hotspots for biological diversity. The founding fathers of modern day botany in China all trained at western institutions in Europe and America during the early decades of last century. In particular, a number of these eminent Chinese botanists, Qian Songshu (Prof. S. S. Chien), Hu Xiansu (Dr H. H. Hu of Metasequoia fame), Chen Huanyong (Prof. W. Y. Chun, lead author of Cathaya argyrophylla), Zhong Xinxuan (Prof. H. H. Chung) and Prof. Yung Chen, undertook their training at various institutions at Harvard University between 1916 and 1926 before returning home to estab- lish the initial Chinese botanical research institutions, initiate botanical exploration and create the earliest botanical gardens of China (Li 1944). It is not too much to expect that at least some of them would have had personal encounters with Ernest ‘Chinese’ Wilson who was stationed at the Arnold Arboretum of Harvard between 1910 and 1930 for the final 20 years of his life.

An Overview of the Genus Cotoneaster (Rosaceae): Phytochemistry, Biological Activity, and Toxicology
antioxidants Review An Overview of the Genus Cotoneaster (Rosaceae): Phytochemistry, Biological Activity, and Toxicology Agnieszka Kicel Department of Pharmacognosy, Faculty of Pharmacy, Medical University of Lodz, 1 Muszynskiego, 90-151 Lodz, Poland; [email protected] Received: 18 September 2020; Accepted: 13 October 2020; Published: 16 October 2020 Abstract: Traditional herbal medicines have become a subject of global importance with both medical and economic implications. The regular consumption of herbal drugs has led to serious concerns regarding their quality, effectiveness, and safety. Thus, relevant scientific evidence has become an important criterion for the acceptance of traditional health claims. The genus Cotoneaster Medikus provides numerous species traditionally used in Asian medicine for the treatment of haemorrhoids, diabetes, and cardiovascular diseases. This review summarises the achievements of modern research on the Cotoneaster taxa, including ethnobotany, phytochemistry, pharmacology, and toxicology. To date, more than 90 compounds have been isolated or analytically identified in Cotoneaster leaves, fruits, flowers or twigs. These phytochemicals are categorised into flavonoids, procyanidins, phenolic acids, cotonefurans, cyanogenic glycosides, triterpenes, sterols, fatty acids, volatile compounds, and carbohydrates, and many of them are responsible for Cotoneaster pharmacological properties including antioxidant, anti-inflammatory, antimicrobial, antiparasitic, hepatoprotective, anti-diabetic or anti-dyslipidaemic

Peer-reviewed Journal Articles Abouhaidar, S. S., E. Fereres, and R. W. Harris. 1980. Drought adaptation of 2 species of Cotoneaster. Journal of Horticultural Science 55 (3): 219-227. Authors’ abstract: The transpiration of C. salicifolius and C. lacteus plants previously subjected to mild, moderate or severe water stress was persistently reduced compared to the unstressed controls. For C. salicifolius this was due to partial stomatal closure and to a decrease in leaf area following water stress. For C. lacteus it was mostly due to a lengthy reduction in leaf conductance. In previously unstressed C. salicifolius and C. lacteus water stress had an after-effect on stomatal opening, whereby leaf conductance did not increase readily as plant water status recovered after irrigation. Leaf conductance of C. lacteus plants that underwent several stress cycles increased readily after irrigation, independent of leaf water potentials, which were slower to recover. Chang, C-S., and J.

Simon's Cotoneaster Cotoneaster Simonsii Baker
Simon’s cotoneaster Cotoneaster simonsii Baker Synonyms: n/a Other common name: Himalayan cotoneaster Family: Rosaceae Invasiveness Rank: 42 The invasiveness rank is calculated based on a species’ ecological impacts, biological attributes, distribution, and response to control measures. The ranks are scaled from 0 to 100, with 0 representing a plant that poses no threat to native ecosystems and 100 representing a plant that poses a major threat to native ecosystems. Description Simon’s cotoneaster (Cotoneaster simonsii) is a medium height (2-3 m) thorny shrub occasionally used for landscaping in Alaska. This variety of cotoneaster and others are imported and sold through nurseries and garden centers as ornamental species. Simon’s cotoneaster is deciduous with conspicuous orange-red fruits, orange/scarlet red leaves in the fall with small white to rose-colored flowers. The leaves are dark-green, pubescent and oval-shaped, forming an alternate pattern on the leaf twig. Flowers have 5 petals and are grouped in clusters of 2-5. Corollas (flower petals whorled within sepals) are white with red markings or pinkish, calyces are appressed and hairy; ovaries are inferior and stamens number about 20 (E-Flora BC 2016). Cotoneaster species produce strong, wide spreading, but superficial root systems. Identification to the species level in the Cotoneaster genera requires field visits during flowering and fruiting times. Similar species: Cotoneaster is a common perennial shrub with over 65 species found in the U.S. and Canada. In Alaska, the most common cotoneaster shrubs are Peking cotoneaster (Cotoneaster acutifolius) and Hedge cotoneaster (Cotoneaster lucidus) both of which have black fruit.

The Dendroflora in the Jewish Cemetery
THE DENDROFLORA (TREES FUND) IN THE JEWISH CEMETERY The area of the Jewish cemetery has a plush and diversified dendroflora represented by many deciduous trees, coniferous trees and undergrowth. The trees are mainly concentrated along the sides of the pathways. The cemetery trees also forms a physical fence encircling the perimeter of the cemetery. Presently, the elaboration of a project is in progress with the aim to study the physical condition of the trees and plants inside the Jewish cemetery. Engaged in the realization of the project are professors of entomology and phytopathology of the Belgrade Faculty of Forestry. The task of this diploma paper is a survey of the Jewish Cemetery dendroflora. Exemplary types have been collected, established and described. It can be said of this area that it possesses an abundant dendrofund of exquisite esthetic value. During the process of on-site data gathering and research no evidence of any kind of disease was found except for a number of individual cases of tree desiccation. The conclusion of the paper should propose ways of further plant development within the Jewish cemetery or at least ways to preserve its current state.
