The pantropical weed, Urena lobata L. (Malvaceae) is reported for the first time in Texas. The spread of U. lobata in the U.S.A. and the role of botanic gardens in reducing threats from invasive plants are discussed.

Biodiversity conservation in Botanical Gardens: collection of Cycadales Pers. ex Bercht. & J. Presl representatives in the greenhouses of the Peter the Great Botanical Garden (BIN RAS)

The role of Botanical Gardens in biodiversity conservation is considered. The analysis of the greenhouse collection of Cycadales representatives is carried out. Both the general characteristics of this group of plants (distribution, growth forms, reproduction, taxonomy) and the characteristics of the families and genera Cycadales presented in the collection of the Peter the Great Botanical Garden are given. In the greenhouses, 47 species of Cycadales belonging to 9 genera are grown, all species have a conservation status: CR - 7 species, EN - 10 species, VU - 6 species, NT - 16 species, LC - 8 species.

Botanic Gardens Complement Agricultural Gene Bank in Collecting and Conserving Plant Genetic Diversity.

Originating in Europe in the 16th century, botanic gardens are found in nearly every country in the world. Botanic gardens have had various roles during this time, including as physic gardens, as adaptation centers for commercial crops, as pleasure gardens, and more recently as conservation institutions. The role of botanic gardens in the conservation of Crop Wild Relatives is becoming increasingly important. At least 6000 taxa related to 68 crop genera are maintained by the world's botanic gardens with several gardens having specialist collections. The extent of infra-specific genetic diversity of these Plant Genetic Resources for Food and Agriculture (PGRFA) being conserved is currently unknown, although based on existing evidence it is likely to be low. However, these PGRFA collections, through display and education, play a significant role in linking the public to important issues, including food security and the need to conserve crop diversity. Today there are some 2700 botanic gardens in existence, and they are visited by over 500 million people every year. The majority of these gardens are found in temperate regions. At least 30% of all known plant species are found in botanic garden collections, including 41% of threatened species. These ex situ collections are conserved in a variety of ways, including as seed bank collections. Around 350 botanic gardens together maintain seed collections of 57,000 taxa. These seed bank collections have a variety of uses, including for research and reintroduction.

The changing role of ornamental horticulture in alien plant invasions.

The number of alien plants escaping from cultivation into native ecosystems is increasing steadily. We provide an overview of the historical, contemporary and potential future roles of ornamental horticulture in plant invasions. We show that currently at least 75% and 93% of the global naturalised alien flora is grown in domestic and botanical gardens, respectively. Species grown in gardens also have a larger naturalised range than those that are not. After the Middle Ages, particularly in the 18th and 19th centuries, a global trade network in plants emerged. Since then, cultivated alien species also started to appear in the wild more frequently than non-cultivated aliens globally, particularly during the 19th century. Horticulture still plays a prominent role in current plant introduction, and the monetary value of live-plant imports in different parts of the world is steadily increasing. Historically, botanical gardens-an important component of horticulture-played a major role in displaying, cultivating and distributing new plant discoveries. While the role of botanical gardens in the horticultural supply chain has declined, they are still a significant link, with one-third of institutions involved in retail-plant sales and horticultural research. However, botanical gardens have also become more dependent on commercial nurseries as plant sources, particularly in North America. Plants selected for ornamental purposes are not a random selection of the global flora, and some of the plant characteristics promoted through horticulture, such as fast growth, also promote invasion. Efforts to breed non-invasive plant cultivars are still rare. Socio-economical, technological, and environmental changes will lead to novel patterns of plant introductions and invasion opportunities for the species that are already cultivated. We describe the role that horticulture could play in mediating these changes. We identify current research challenges, and call for more research efforts on the past and current role of horticulture in plant invasions. This is required to develop science-based regulatory frameworks to prevent further plant invasions.

Botanic Gardens as Communicators of Plant Diversity and Conservation

This paper presents a unique survey on the role of botanic gardens as educational institutions that communicate plant diversity and conservation. An online survey was created to evaluate the present strategies developed by botanic gardens from all over the world to their visiting public. Dependent on their resources, either human, financial or both, all of them look for the accomplishment of Global Strategy for Plant Conservation’ target 14, promoting education on plants and awareness on human impacts in plant diversity loss. However, an educational group/department is more common in botanic gardens owned by the central government compared to the private, non-profit botanic gardens. The diversity of activities on plant diversity and conservation is influenced by the size and the number of staff in the garden. Only half of the surveyed botanic gardens have rooms exclusively assigned for educational activities and even less have garden spots for the same purpose. Online resources are particularly restricted to North America and Oceania botanic gardens. Although climate change is a brand new subject that could attract public to the garden, the most part of the gardens address biodiversity and plant identification as major themes of communication. Besides species label information and interpretation panels, self-guided visits, guided visits or activities/workshops are the common offers for public attraction. School visitors are still less than half of the total visitors and cover children from 6 to 13 years-old. These follow more guided visits and activities while general public choose self-guided visits.

Do the introductions by botanical gardens facilitate the invasion of Solidago canadensis (Asterceae) in China?

SummaryMany invasive plants have long been suspected of firstly being introduced and cultivated by a local botanical garden or nursery and then escaping into the field after adapting to the novel environment. The role of botanical gardens in the spread of invasive plants has not yet been explored experimentally. In this article, we studied the possible roles of two botanical gardens in the spread of invasive Solidago canadensis (Asterceae) in China by analysing genetic relationships of invasive and native (United States) populations with intersimple sequence repeats markers. Our results showed a high genetic variation (mean He = 0.292) and a large proportion of genetic variation (85.6%) residing within populations. Solidago canadensis was possibly introduced firstly into eastern China. The plants from Lushan Botanical Garden showed distant genetic distance from all of the other populations, suggesting that this botanical garden had little effect on the invasion of S. canadensis. Populations from Wuhan Botanical Garden in central China, however, showed close genetic relationships with local populations and populations in west and south‐west China, suggesting gene exchange between these populations. Thus, risk assessment is critical for plant introduction and conservation, as introductions of alien plants by botanical gardens may facilitate plant invasions, while plants conserved in botanical gardens may be at risk by surrounding plant invasions.

The role of botanic gardens in the twenty-first century.

Abstract Botanic gardens and their functions and role in society have evolved over time. Originally established for study of medicinal plants in the mid-sixteenth century, they morphed into active sites for introduction, cultivation and dissemination of economically important crops during European expansion of colonies in Asia, America and Africa during the seventeenth-nineteenth centuries. During the second half of the twentieth century, importance was placed on the need for conservation and sustainable use of biodiversity. In the twenty-first century, botanic gardens are challenged to address issues that extend beyond the garden walls by placing social and environmental responsibility as key mission drivers.

Recreation, education, conservation: the multiple roles of botanic gardens in Australia

Drawing on the theories that underpin systems theory and conflict management, this paper considers the main role or purpose of botanic gardens in Australia which is based on three perspectives: those of visitors to gardens; garden volunteers; and gardens as organizations. Using a multi-methods approach including written questionnaires, focus groups, and document analysis, a number of key roles were identified by each stakeholder group: recreation (visitors); education (volunteers); and conservation (gardens as organizations). In view of these findings, it is suggested that garden management would benefit from increased attention to visitor wants and needs through an understanding of the main activities undertaken at gardens, their perceptions of visitor service quality, and the values that people place on gardens.

Botanic gardens in the age of climate change

We are facing an unprecedented plant diversity crisis. If current trends in habitat conversion, over-exploitation, alien species invasions, and climate change continue, up to 50% of the world’s vascular plant flora is expected to become threatened with extinction within the twenty-first century (Pitman and Jorgensen 2002; Root et al. 2003; Hahns et al. 2009). Climate change seems to rapidly have become recognized as the primary threat to many plants. In Europe, more than half of the vascular plant flora may become endangered by the year 2080 as a result of climatic changes (Thuiller et al. 2005), and the first unfavourable trends in the threat status of plant species attributable to such changes have already been observed in successive Red List evaluations (Rassi et al. 2010). The Global Strategy for Plant Conservation (GSPC; Secretariat of the CBD 2002) was adopted under the Convention on Biological Diversity (CBD) in 2002 as a policy response to the dire situation of plant life, and an updated version of the strategy up to 2020 was recently approved at the Conference of Parties to the CBD in Nagoya (Convention of Biological Diversity 2010). Botanic gardens of the world, largely through their advocate Botanic Gardens Conservation International (BGCI), were pivotal in the writing and promotion of the GSPC, and have continued in this role in the implementation, follow-up, and further development of the strategy (Secretariat of the CBD 2009). The role of botanic gardens in the creation and mainstreaming of the GSPC has been a manifestation of the fact that these time-honoured institutions have fully adopted a fourth main task—conservation—alongside their traditional responsibilities in research, teaching, and public education in the field of botany. However, the GSPC puts due emphasis also on these traditional tasks through the recognition that successful conservation must be based on a solid knowledge base and that the understanding of the value of plant diversity must also be disseminated to the widest possible audience in order to make a difference

‘All netted together’: is there a need for cultural consilience in the face of extinction?

Professor Stephen Hopper has suggested that ‘possibly the most significant future challenge facing plant conservation is the achievement of a global shift in value systems towards acceptance of the old cultural wisdom that humans are part of, not separate from, nature’. Here I examine this challenge for contemporary humanity experiencing increasingly divergent ‘lifeworlds’ and ask if it is possible to be ‘all netted together’, and achieve cultural consilience in the face of increasing plant extinction. The first part of the article explores a hybrid approach to botanical education, where ‘border crossings’ between ‘Pokemon’ and plant-based inquiry might facilitate 21st century urban children to engage more intimately with the living world. The second part highlights how botanic gardens can facilitate expressions of lost botanical knowledge carried through human migration from rural to urban contexts. The article ends with a discussion intended to provoke interdisciplinary discourse between botanical science and botanical education, contextualised within the wider literature that examines the role of botanic gardens.

The role of botanic gardens as resource and introduction centres in the face of global change

One of the consequences of global change, especially demographic and climatic, will be a demand for novel plant germplasm of all kinds suited to the new ecoclimatic conditions predicted and plant introduction will assume a new importance. As a consequence, botanic gardens will face an unprecedented opportunity to regain their role as introduction centres and become major actors in the assessment of new germplasm, both of ornamentals as well as other economically important plants. Plant introduction has remained largely unchanged over the past 400 years and is as often ad hoc, poorly organized and insufficiently collaborative, but if it is to meet the needs of today’s situation it needs to be overhauled. In particular: (1) the basis of plant introduction needs to be broadened; (2) closer cooperation with agricultural genebanks should be established; (3) agreement should be reached between botanic gardens and the agricultural sector on their respective responsibilities (4) the quality and sampling of the accessions should be more strictly controlled; (5) proper evaluation of the introductions before they are disseminated; (6) information on the accessions of introduced plants and their fate needs to be more effectively maintained and disseminated; and (7) full cognizance should be taken of policies to protect against invasive species and care should be taken to evaluate the risks that new introductions might represent. Finally, consideration should be given to preparing a set of guidelines or even a code of conduct for plant introductions by botanic gardens in association with other agencies.

Role of the environmental factor in the competitiveness of the region

The article shows the role of environmental factor in the competitiveness of the region. The issue of the country's image and the region is considered according to ecology and touristic appeal. We consider the modern role of botanical gardens and their transformation from scientific horticultural organizations to the objects of multi-use facilities type, for a regional multi-utility. The experience of an innovative project of creation of Russia's first environmental technological park and tourist-recreational zone on the basis of the university botanical garden in Irkutsk using the public-private partnership is stated.

Redefining the role of botanic gardens for the future: a personal challenge

The paper sketches the planning of the Royal Botanic Garden at Tel Al Rumman. This has been not only a personal struggle for the author, but also the result of a remarkable public campaign in Jordan, which contains many lessons. With the threat of climate change and increased rate of biodiversity loss it has become imperative that we reverse the situation if we are to live a life of dignity. The RBG Jordan is one concentrated effort to achieve a new balance.

The role of botanical gardens in climate change research

Botanical gardens have a unique set of resources that allows them to host important climate change research projects not easily undertaken elsewhere. These resources include controlled growing conditions, living collections with broad taxonomic representation, meticulous record-keeping, networks spanning wide geographic areas, and knowledgeable staff. Indeed, botanical gardens have already contributed significantly to our understanding of biological responses to climate change, particularly the effects of temperature on the timing of flowering and leaf-out. They have also made significant contributions to the understanding of the relationships among climate, physiology, and anatomy. Gardens are finding new uses for traditional research tools such as herbarium specimens and historical photographs, which are increasingly being used to obtain information on past plant behavior. Additional work on invasive species and comparative studies of responses to climatic variation are providing insights on important ecological, evolutionary, and management questions. With their large collections of plant species from throughout the world and excellent herbaria, botanical gardens are well positioned to expand their current activities to continue to provide leadership in climate change research and education.

Biocultural diversity should be a priority for conservation

Picking up on a Nature article on the role of botanic gardens in conservation, Christopher Dunn, director of the Lyon Arboretum in Hawaii, makes the point that biological conservation and cultural and linguistic conservation are intimately linked. The maintenance of 'biocultural diversity', rather than biodiversity should be the measure of conservational success.

EDUKACINĖS VEIKLOS INFRASTRUKTŪRA BOTANIKOS SODUOSE IR PARKUOSE: PIETŲ VOKIETIJOS PATIRTIS

Some facilities of education activities in south Germany botanical gardens and parks are presented in this article. Research was carried out in Munchen-Nymphenburg, Alpengarten Schachen and Augsburg botanical gardens, Munchen zoological garden, Munchen city parks (in the Museum of Man and Nature). The role of botanic gardens is as an advocate for the maintenance of biodiversity and therefore botanic gardens need to reorient their education programmes and incorporate a vision for a more socially and environmentally sustainable future. Botanic and zoo gardens can use a variety of techniques to convey these messages from guided tours, cultural activities and exhibitions to interpret signs and media such as the internet, radio, television and newspapers. Botanic gardens should develop and promote these institutions as centers for environmental education to schools and develop child-friendly policies and train staff in these policies, conduct regular audits to ensure that the gardens is 'child friendly' e. g. access points, eating areas, storage areas, activity/play areas. The subject areas covered by the Museum of Man and Nature are: the history of the earth and its forms of life, biodiversity, man’s place within the natural world, man’s role in shaping the natural world. The Museum presents an interesting and entertaining approach to natural science, in line with modern educational theory. Authentic natural objects, reproductions, models, interactive exhibits and audio-visual programs are employed to create a lively and stimulating setting. The section “Natural history playtime” successfully combines traditional and modern exhibits and appeals to young and old alike. Attractive exhibits and a convenient location make the Museum of Man and Nature a worthwhile destination for visitors of all ages. The official educational mission of this Museum “… to instruct and inform humans about themselves, their environment and about the threats to nature posed by technical civilization”. Key words: botanic garden, zoological garden, parks, education, natural science.
