The growth characteristics and horticultural merit of eight Asian trees that are generally unknown in North American horticulture are discussed. Seven deciduous trees (Sorbus hupehensis 'Pink Pagoda', Sorbus pallescens, Acer tschonoskii var. rubripes, Acer carpinifolium, Dipteronia sinensis, Heptacodium miconioides, Rehderodendron macrocarpum), and one conifer, Taiwania cryptomerioides, have been observed for several years at the University of British Columbia (UBC) Botanical Garden in Vancouver, to determine their suitability for more widespread cultivation as street, park or garden trees.

The United Nations 2030 Agenda for Sustainable Development outlines 17 goals for the wellbeing of people and the planet. The purpose of this study was to understand how University of British Columbia Botanical Garden (UBCBG) contributes to the United Nations Sustainable Development Goals (UN-SDGs) and to identify opportunities for future action. To address this, we worked across departments to assess our programs and activities against the UN-SDG 17 goals and 169 targets. The UN-SDG indicators were only used to identify potential metrics that could be consider for future tracking. The main activities of UBCBG include ex situ plant conservation, sustainability education and community engagement. Our results found that UBCBG contributes to 12 of the 17 goals and 24 of the 169 targets. The two UN-SDGs with more targets aligned to UBCBG’s activities were Goal 15—Life on Land and Goal 12—Responsible Consumption and Production. Through its partnerships with other botanical gardens, research institutions and the regional government, the Garden amplifies its work at a global, national and regional level. We are re-imagining the role of botanical gardens in an age of equity, decolonization, the biodiversity crisis and the climate emergency. Since the UN-SDGs address both nature and people, they are an appropriate framework to guide our work.

Dr Albert Douglas Courtemanche was born in Gravenhurst, Ontario on November 16, 1929. In 1949, he was accepted to the University of Toronto Medical School, graduating in 1955. After completing his internship at the Toronto General Hospital and at the Hospital for Sick Children, he completed his surgical training in Vancouver and in the United Kingdom. When Dr Courtemanche returned from his training in 1962, he joined Dr Cowan on the surgical staff at the Vancouver General Hospital. He was responsible for establishing a new plastic surgery ward, a dedicated operating room (OR), an integrated burn unit and also starting the UBC plastic surgery training program. Dr Courtemanche became involved in working with the Royal College, first as an examiner and then as the Chairman of the Plastic Surgery Exam Board in 1981. He eventually became the first and only plastic surgeon to ever hold the position as President of the Royal College. Dr Courtemanche emphasized throughout his career the importance of teaching and role modeling. A very proud moment in Dr Courtemanche’s career was when his son Douglas became a pediatric plastic surgeon. After retiring Dr Courtemanche became a volunteer at the VanDusen Botanical Garden and completed their Master Gardeners Program.

Rhamnus purshiana, or cascara, is a deciduous tall shrub or small tree as much as 9 m high with thin, smooth, silver-gray bark. It is often present in shady sites in redwood and mixed evergreen forests of the North Ameri-can west coast, from British Columbia to northern California. In July 2005, symptomatic leaves with irregular, black spots, 2 to 5 mm in diameter and concentrated toward the tips, were collected from four cascara plants in the Samuel P. Taylor State Park, Marin County, California. There was no evidence of defoliation. Pieces of necrotic tissue were plated on selective medium (PARP) and maintained at 19°C for 2 weeks. A Phytophthora sp. was consistently isolated and it was identified as P. ramorum on the basis of morphological and molecular traits published previously (3,4). The P. ramorum isolate Pr-418 has been deposited in the American Type Culture Collection (ATCC MYA-3676) and a portion of the internal transcribed sequence (ITS) of rDNA has been deposited in the NCBI database (GenBank Accession No. DQ168874). Koch's postulates were completed using the leaf-dip method (2) on detached leaves collected from three cascara plants growing at the University of California Botanical Garden at Berkeley. Zoospore inoculum was prepared by flooding a 2-week-old culture growing on V8 agar with sterile water for 4 days. The liquid was filtered after cold shocking at 4°C for 30 min and incubated at room temperature for 1 h. Fifteen leaves were dipped in the resulting zoospore suspension (1.6 × 104 zoospores per ml) for either 1 min (experiment 1) or overnight (experiment 2). Leaves used as negative controls were dipped in sterile water. After removal from the inoculum, excess liquid was allowed to drain. Leaves were maintained in a moist chamber at 19°C with 13 h of natural light for 1 week. After 3 days of incubation, necrotic spots similar to those observed in the field had developed on leaves in experiment 2, while no symptoms were observed in experiment 1. Necrotic lesions were observed on 12 and 15 of 15 leaves in experiments 1 and 2, respectively, after 7 days of incubation. For each leaf, the necrotic area and percent necrosis was determined by placing the leaves in a flatbed scanner and processing the images with Assess (Version 1.01; The American Phytopathological Society, St. Paul, MN). Lesions extended from the tip of the leaves and covered 3 ± 1% of the total leaf area in experiment 1 and 33 ± 3% in experiment 2. Reisolation of P. ramorum on PARP was successful for all inoculated leaves. P. ramorum was never isolated from negative controls and no symptoms of infection were observed. The leaf-dip inoculation method is a rapid and reliable indicator of host susceptibility to P. ramorum, with many species developing necrosis when exposed to high concentrations of zoospores (3). Our results show that exposure time to the pathogen can play an important role in the development of symptoms. R. purshiana has been previously reported as a host in Oregon (1,2), but to our knowledge, this is the first report of cascara as a natural host of P. ramorum in the state of California. Our results confirm those from Oregon (2). The impact of infection by P. ramorum on cascara is unknown. References: (1) J. M. Davidson et al. Plant Health Prog. DOI:10.1094/PHP-2003-0707-01-DG, 2003.

In this work, we investigate the layout and architecture of campuses in terms of the role of natural landscapes in their space. Campus structures are considered as spatial grids in the context of their interaction with natural landscapes and their components. We studied the experience of designing a botanical garden in Columbia in a hot humid climate, the Polytechnic University in Ben Guerir in the climate of the Western Sahara and the Russian Far Eastern Federal University on Russky Island near Vladivostok. An analysis of the existing layout and development of the campus of the Irkutsk National Research Technical University was carried out. Scientific foundations for arranging interaction between campuses and environmental conditions were determined, referred to as natural conformity principles. Architectural and planning grids are the spatial basis for campus organization. The cells of planning grids are the courtyards of buildings of various purposes, squares and other public spaces. Pedestrian boulevards (malls) connect the cells and the campus as a whole. The natural conformity of the campus depends on the consistency of cells, connections and boundaries of its architectural and spatial structure with the relief, groups and arrays of plantations, as well as with the climate, light and water bodies – landscape spaces. Another important factor is orientation of the building layout to natural attractors, i.e., the most attractive natural landscapes.

This paper discusses local understanding of plants and habitats, based on the linguistic evidence [terms for plants and (or) habitats] gathered from ethnobotanical and ethnoecological field work conducted with several Dene Nations of the Canadian northwestern boreal forest and adjacent regions. Nations involved in the study include Gwich’in (Mackenzie Delta Region), Sahtú’otine’ (Great Bear Lake), Kaska Dena (southern Yukon), and Witsuwit’en (northwest British Columbia). Key plant-related habitats include meadow, “swamp”, forest, “willows”, and “brush”. The ethnobotanical classification of willows is explored in conjunction with the explanation of the Dene habitat concept. In local classifications, ‘willow’ is not co-extensive with the genus Salix , but includes a variety of medium to tall woody shrubs that lack either conspicuous flowers, ‘berries’, or thorns; these may include shrubby species of Salix, Alnus , Cornus , and Betula . Shoreline and alpine environments are also discussed as plant habitats. Dene use of alpine environments and resources is ancient, according to the results of recent alpine ice patch research in the Yukon region. The Human dimensions of habitat knowledge are presented. Indigenous concepts of plant taxa and of landscape associations or habitats may differ substantially from those of scientific botany and ecology, and are based in a holistic and interactive ethnoecology.

Knowledge and practices of indigenous peoples relating to local plants used for food, medicine, materials, and other purposes are threatened in many parts of the world. The reasons for declining knowledge and use of traditional resources are complex and multifaceted. We review a series of case examples of culturally valued food plants in British Columbia and identify a suite of interacting social and environmental factors that have resulted in decreased use of and dwindling cultural knowledge about these plants over the past 150 years. Reasons for this loss include compounding influences of changing knowledge systems owing to religious conversion and residential schools, loss of indigenous languages, loss of time and opportunity for traditional practices owing to participation in the wage economy, increasing urbanization of indigenous populations, loss of access to traditional resources, restriction of management practices for sustaining these resources, and most recently, forces of globalization and industrialization. Efforts to renew and restore traditional practices and relationships with plants and environments must recognize the cumulative effects of these factors and find ways to retain and reinforce the knowledge and practices still held by individuals and communities, to reverse some of the negative influences on cultural retention, and to develop new, relevant, and effective ways to revitalize languages, cultures, and ethnobotanical knowledge within contemporary contexts.

DNA fingerprinting is a potentially powerful molecular genetic technique that can be used to distinguish subtle differences in genome structure among closely related genotypes, such as many horticultural varieties. A DNA fingerprinting project is currently in progress at the Univ. of British Columbia (UBC) Biotechnology Laboratory to produce a set of DNA markers and an easy, reliable, and legally recognized analysis protocol that will enable the UBC Botanical Garden Plant Introduction Scheme (PISBG) to unambiguously identify any of their released varieties, even in dormant or juvenile form, wherever it is being propagated or sold. High-quality genomic DNA was isolated from the leaf samples of six PISBG species (Anagallis monellii, Artemesia stelleriana, Clematis, Genista pilosa, Microbiota decussata, and Penstemon fruticosa) using a modified CTAB DNA isolation protocol, and further purified by cesium chloride/ethidium bromide gradient. Samples of these genomic DNA preparations (10 ng) were then amplified by a 45-cycle polymerase chain reaction (PCR) protocol using 1.5-μm 10-nucleotide primers of arbitrary nucleotide sequence that amplify a variety of sites distributed across the genome. Following the amplification, PCR products [random amplified polymorphic DNA (RAPD) markers] were separated by agarose gel electrophoresis and visualized by ethidium bromide staining. More than 70% of the 51 primers tested so far generated distinctive banding patterns (2–11 bands) with DNA samples from each species. Subtle changes in the genome or differences between genotypes can be detected by screening a series of such primers against DNA samples from the genotypes in question. Once a RAPD primer has been identified that consistently generates a different banding pattern between genotypes, it can be used as an identification tool for discriminating between those genotypes at any time in the future.

PrécisIn 1989 the Canadian Broadcasting Corporation aired a five-part radio series, “It's a Matter of Survival.” Anita Gordon was the originator and executive producer of the series. David Suzuki is Professor of Zoology at the University of British Columbia and the host of “The Nature of Things,” a science television program. This book grew out of the radio series and is described on the jacket cover by Edward O. Wilson as “the best piece of extended environmental journalism I've seen to date.” Cited in the end notes are publications in the popular press (e.g., The New York Times) and CBC interviews with a range of environmental commentators such as Lester Brown and Paul Erlich. The book indicts the environmental irresponsibility of human beings as a species and is intended as a response to the radio listeners who wrote to the CBC following the 1989 broadcasts asking what they could do to forestall environmental catastrophe.Gordon and Suzuki begin with a hypothetical glimpse into the “nightmare world of 2040.” Subsequent chapters question how we reached the stage of environmental crisis, explore myths that have blinded us to the crisis, predict future growth trends, describe the ethic of domination over nature, and review the devastation wrought by prevailing definitions of “progress.” The authors end with an alternative (and positive) look at the year 2040 that can be possible if the resolutions they discuss are sought. They conclude that humans as a species have “lost the ability to hear the warning cries of nature” (p. 234), but they hold the hope that humans can emerge from the crisis with a “new collective image of ourselves as a species integrated into the natural world” (p. 238).

Rodney Hill was born on 11 June 1921 in Leeds, and educated at Leeds Grammar School. He went up to Cambridge University in October 1939, with a Major Scholarship at Pembroke College. He graduated BA with first-class honours in 1942 in the Mathematical Tripos. Volunteering for war work immediately, he worked in full-time government service on ballistics in the Cambridge Mathematical Laboratory, and on the plasticity of metals in the Cavendish Laboratory. In 1943 he moved to the Armament Research Department at Fort Halstead in Kent, for three years. Here he was involved in, for example, the modelling of armour penetration by projectiles. This established his expertise in the Mathematical Theory of Plasticity, in which he became a world-recognized leader via the writing of a renowned book with that title (still in print after 60 years) and 170 research articles with eventually 26 collaborators. He had more than 10 research students. In 1963 he wrote a textbook, Principles of dynamics , based on his lectures to undergraduates. Subsequent appointments were at the British Iron and Steel Research Association in Sheffield, at Bristol University, and then as Professor of Applied Mathematics at Nottingham University (1953–62), and at Cambridge University. He retired in 1979 but continued with active research for more than another 20 years. Hill was elected a Fellow of the Royal Society in 1961, whose Royal Medal he received in 1993. He received the Honorary Degree of DSc from the Universities of Manchester (1976) and Bath (1978). He was awarded the von Karman Medal of the American Society of Civil Engineers in 1978, and the Panetti Medal of the Turin Academy in 1988. In 1982 The Rodney Hill 60th Anniversary Volume called Mechanics of solids was published, edited by H. G. Hopkins and M. J. Sewell. It contains 19 articles by 23 contributors in 693 pages. The Rodney Hill Prize in Solid Mechanics (US $25 000, at four-yearly intervals) has been established by Elsevier Ltd. It was awarded first in 2008 (Ortiz) and then in 2012 (Gao). A principal relaxation of Hill for 50 years was in extended botanical expeditions with his wife, Jeanne, in many parts of the English countryside, searching for, and identifying and recording, many species of wild flowers and fungi; and in the cultivation of a garden at home. Rodney Hill married Jeanne Wickens in 1945. She died in 2003. They had one daughter, Caroline, who survives them. Rodney died in Cambridge on 2 February 2011.

Abstract Francis Buchanan’s temporary successor at the Botanic Garden, Nathaniel Wallich (né Nathanael Wulff) (1786-1854), was born in Copenhagen, the son of a Jewish merchant. He had been a pupil of Professor Martin Yahl, the author of Symbolae botanicae (1790-4), at the University of Copenhagen, and, on qualifying as a surgeon in 1806, left for the Danish settlement at Serampore on the River Hooghly opposite Barrackpore with an additional commission to collect plants and seeds for the Botanical Garden in Copenhagen. When he took up his appointment as the settlement’s surgeon in 1807, the British fleet had bombarded Copenhagen and following the Company’s annexation of Serampore in 1808, Wallich and his fellow countrymen became prisoners of war. He was released from captivity in June 1809 at the behest of William Roxburgh with the authorization of the Bengal Government to employ him in the Botanic Garden. Roxburgh proposed sending him to the eastern frontier of the Company’s territory to collect plants, an assignment that appealed to Wallich who had professed that knowledge rather than wealth was to be his motivation in life. It comes as a surprise, therefore, that he should soon relinquish this potentially attractive mission to return to Serampore. It would appear he declined the opportunity to be a field botanist because he considered his travelling allowance to be inadequate.
