A new international initiative for plant conservation was first called for as a resolution of the International Botanical Congress in 1999. The natural home for such an initiative was considered to be the Convention on Biological Diversity (CBD), and the Conference of the Parties (COP) to the CBD agreed to consider a Global Strategy for Plant Conservation (GSPC) at its 5th meeting in 2000. It was proposed that the GSPC could provide an innovative model approach for target setting within the CBD and, prior to COP5, a series of inter-sessional papers on proposed targets and their justification were developed by plant conservation experts. Key factors that ensured the adoption of the GSPC by the CBD in 2002 included: (1) ensuring that prior to and during COP5, key Parties in each region were supportive of the Strategy; (2) setting targets at the global level and not attempting to impose these nationally; and (3) the offer by Botanic Gardens Conservation International (BGCI) to support a GSPC position in the CBD Secretariat for 3 years, which provided a clear indication of the support for the GSPC from non-governmental organizations (NGO). 相似文献

Ex situ seed conservation is an effective strategy to help safeguarding plants from extinction. The updated Global Strategy for Plant Conservation’s (GSPC) Target 8 aims to include 75% of threatened plant species in ex situ collections by 2020, preferably in the country of origin. Halfway through the updated GSPC program, we evaluate the current state of knowledge and practice of ex situ seed conservation of threatened species from megadiverse Brazilian flora, contributing to this Target. We identify knowledge gaps and costs to achieve Target 8 through seed banking in Brazil within the time constraints of the GSPC and in a scenario of recent science budget funding cuts. Knowledge on seed storage behavior is available only for 24 Brazilian species (1.3%). Seed desiccation tolerance was concluded for 175 of 228 species, feasibly allowing safe storage of most Brazilian species at sub-zero temperatures. However, only 26 species (1.3%) are effectively banked in research institutions. Surprisingly, the percentage of banked threatened species hardly increased in the first 5 years since the update of the Target (0.55%, 2011–2015), and Brazil now faces the challenge of banking almost 1500 species during 2016–2020. Despite a major lack of commitment of Brazilian institutions and of knowledge to achieve the Target, the costs for banking the remaining species were estimated to be only US$3.9 million. We call for a nationwide coordinated effort of government agencies, policy makers and research institutions to include ex situ seed conservation in the environmental agenda to pursue achievement of the Target by 2020. 相似文献

The Global Strategy for Plant Conservation (GSPC) was adopted by the Parties to the Convention on Biological Diversity (CBD)
in 2002. Staff at the Royal Botanic Gardens Kew were closely involved in the development of the GSPC and contributed to the
development of several of the targets and the plan of work which resulted from its adoption. The GSPC has become a key document
for Kew to help guide its conservation policy and implementation. The UK Overseas Territories (UKOTs) Programme is one of
Kew’s cross-departmental science teams whose members work in collaboration with UKOT Governments and NGOs on conservation
projects with the overall aim of supporting them in the implementation of the GSPC and in achieving its targets. The GSPC
has provided an excellent overall framework to help shape conservation strategy, planning, and action in UKOTs. Like many
small islands, UKOTs face a wide range of challenges in conserving their biodiversity and retaining ecosystem services whilst
enabling development and maintaining livelihoods. Habitat loss and fragmentation, invasive alien species, development, and
the increasing threat of global climate change present the most significant conservation challenges. At the heart of the UKOTs
programme is a comprehensive work plan of specimen and data collection, mapping and capacity building in Territories plus
facilitating access to historical specimens and data held at Kew. This enables progress towards achieving Targets 1, 2 and
3 (understanding and documenting plant diversity) and Targets 5, 7, 8 and 10 (conservation of plant diversity). All of these
activities are accompanied by an extensive programme of capacity building to help support the development of technical skills
and infrastructure to enable UKOTs to implement the GSPC (Targets 15 and 16) and the production of materials and interactions
with schools and community groups to promote education and awareness-raising of plant conservation to achieve Target 14. UKOTs
have been working with RBG Kew to prioritise activities in order to implement the GSPC and to identify those targets of most
relevance locally. The main focus has been in documenting and understanding plant diversity and Targets 1 and 2 are close
to completion for most UKOTs with good developments towards Target 3 for many. There is mixed progress with Objective 2 of
the GSPC: conserving plant diversity. Excellent progress has been made with the ex situ Target 8, but more limited progress with the in situ targets and plant species still face many threats. Some Territories, most notably the Falkland Islands have made a good start
with an Important Plant Areas programme. Although good progress has been made in documenting invasive species, there is major
resource investment needed to implement the invasive species control strategies that have been identified. Good progress has
been made with Target 14 and awareness is increasing, but there is a definite need for mainstreaming plant conservation issues.
Some progress with Objective 5, building capacity for plant conservation, has been made, but a large ‘capacity gap’ remains
and more trained personnel are needed with improved facilities and resources in order to implement the GSPC and meet its demanding
targets. The GSPC has provided a unifying framework to enable conservation implementation across the UK’s Overseas Territories
and will continue to do so in the post-2010 period. 相似文献

Increasing the number of species conserved ex situ in Megadiverse countries is a major task exacerbated by many intricate factors including: biome complexity, wide range of biodiversity and an incomplete knowledge of life cycles, reproductive strategies, adaptations and species interactions. Although, establishing safe reserves is a crucial conservation measure their security and effective maintenance can be unfavourably compromised by climate change and the risks incurred by socioeconomic instability and changes in land use. Anthropogenic impacts, non-sustainable practices and habitat erosion have motivated current international efforts which focused on Brazil as host of ‘Rio+20’ the United Nation's twentieth anniversary conference on sustainable development. The revised targets of the Global Strategy for Plant Conservation (GSPC) are responses to species decline and realizing Target 8, which concerns ex situ conservation, places the heaviest burdens on countries that are custodians of the highest levels of global biodiversity. At the scientific level, ex situ conservation of endemic species in genebanks is often hindered by a lack of information about molecular genetics and problematic (recalcitrant) storage behaviors that restrict the preservation of flora native to Megadiverse countries. The potential for applying the ‘Biospecimen Science’ paradigm in expediting conservation in biodiversity-rich biomes is considered using Brazil as an exemplar of a Megadiverse country. The impacts of process chains on the quality of preserved plant germplasm and using evidence-based research to improve conservation outcomes, risk and quality management systems are appraised. The Biospecimen Science approach is not intended to displace conventional conservation practices but rather, to enhance their effectiveness in terms of the scale and efficiency of their scientific and technical operations. 相似文献

The European flora is of global significance but many species are facing an ever increasing range of threats, especially the
growing impacts of climate change. While various estimates have been made for the number of threatened plant species in Europe,
an up-to-date European plant Red List does not presently exist. Target 8 of the Global Strategy for Plant Conservation (GSPC)
calls for 60% of threatened plant species to be conserved in ex situ collections by 2010. In the absence of a European plant
Red List, it is difficult to monitor progress at the regional level towards this target. To address this gap Botanic Gardens
Conservation International (BGCI) has developed a consolidated list of European threatened species as a step towards a formal
Red List. The database consists of national Red List data from 28 European countries and includes records for over 11,000
taxa. National Red List data were supplemented by information on the critically endangered plants of Europe provided by the
Museum National d’Histoire Naturelle/European Topic Centre on Biological Diversity and the Conservatoire Botanique National
de Brest. A list of regionally threatened species was extracted from the database and screened against BGCI’s database of
plants in cultivation in botanic gardens (PlantSearch) and ENSCONET’s (European Native Seed Conservation Network) database
of plants conserved in European seed banks. This analysis revealed that 42% of European threatened species are currently included
in ex situ conservation programmes in Europe. 相似文献

The Global Strategy for Plant Conservation (GSPC) was the first such effort under the Convention on Biological Diversity (CBD), and had gone through a 3-year process to reach the level of maturity that enabled it to be approved by consensus by all Governments present at the key session in The Hague in April 2002. It provided a model for subsequent CBD workplans, with targets, and undoubtedly contributed to the 2010 target of reducing the rate of biodiversity loss. In the event, few of the targets were achieved, because of numerous constraints at both policy and implementation levels. Even so, the GSPC stands as an important milestone in the global effort to conserve biodiversity. However, few plant scientists can be satisfied that the essential steps are being taken to ensure the conservation of plants, although, of course, plant scientists are only one part of the complex effort that will be required. This paper offers some suggestions that might be worth consideration, building on the basic principle in politics that a strong constituency is necessary to victory. In other words, although plant scientists play a crucial role, plant conservation is too important to leave in their hands alone; far broader support is required, including from the private sector, agriculture, forestry, trade, economics, tourism and even the military. Although botanical science provides a solid foundation, other branches of science are also important, ranging from anthropology to zoology. The legal profession also has important contributions to make (as well as the ability to hamper progress – for example through using issues such as access and benefit sharing to limit the exchange of genetic materials for even noncommercial use). 2010 was the United Nations Year of Biodiversity, and the GSPC targets reached their due date. It therefore seems timely to add some additional perspectives to the effort to update the GSPC. This paper suggests ways to reach a far broader constituency, provides tools to those who are expected to achieve the targets, and suggests ways to build a strong international constituency to conserve the world's botanical wealth. 相似文献

The Global Strategy for Plant Conservation (GSPC) aims to protect 50% of the most important areas for plant diversity by 2010. This study selects sets of 1-degree grid cells for 37 sub-Saharan African countries on the basis of a large database of plant species distributions. We use two reserve selection algorithms that attempt to satisfy two of the criteria set by the GSPC. The grid cells selected as important plant cells (IPCs) are compared between algorithms and in terms of country and continental rankings between cells. The conservation value of the selected grid cells are then considered in relation to their future species complement given the predicted climate change in three future periods (2025, 2055, and 2085). This analysis uses predicted climate suitability for individual species from a previous modelling exercise.
We find that a country-by-country conservation approach is suitable for capturing most, but not all, continentally IPCs. The complementarity-based reserve selection algorithms suggest conservation of a similar set of grid cells, suggesting that areas of high plant diversity and rarity may be well protected by a single pattern of conservation activity.
Although climatic conditions are predicted to deteriorate for many species under predicted climate change, the cells selected by the algorithms are less affected by climate change predictions than non-selected cells. For the plant species that maintain areas of climatic suitability in the future, the selected set will include cells with climate that is highly suitable for the species in the future. The selected cells are also predicted to conserve a large proportion of the species richness remaining across the continent under climate change, despite the network of cells being less optimal in terms of future predicted distributions.
Limitations to the modelling are discussed in relation to the policy implications for those implementing the GSPC. 相似文献

The latest IUCN statistics show that of over 12,000 plant species, 70% are threatened, 19% are critically endangered and 28
species are extinct in the wild. Target 8 of the Global Strategy for Plant Conservation (GSPC) highlights the importance of
ex situ conservation of critically endangered plants. Long-term germplasm storage for species with recalcitrant seeds needs alternative
measures. In vitro methods complement seed banking and other ex situ measures and are vital for long-term conservation. Conservation Biotechnology at RBG Kew is currently working on a number
of rare and threatened recalcitrant species from biodiversity-rich areas of the world to develop good quality in vitro propagules for cryopreservation, recovery and restoration projects. The importance of successful in vitro propagation methods, transplantation technologies, cryopreservation and international networking for the integrated conservation
of these species are discussed in detail. 相似文献

A complete listing of the world's known plant species has long been considered desirable but has remained an elusive target for generations of botanists. The adoption of the Global Strategy for Plant Conservation has reinforced the urgent need for a global plant checklist to support, facilitate and monitor the conservation and sustainable use of plant diversity worldwide. The increasing availability of large databases of biological information over the Internet has demonstrated that many of the obstacles to the collation and dissemination of vast, shared datasets can be overcome. We examine the challenges that still remain to be addressed if the botanical community is to achieve its ambitious objective of delivering a working list of all known plant species by 2010. 相似文献

Plant diversity and conservation in China: planning a strategic bioresource for a sustainable future
Huang H 《Botanical journal of the Linnean Society. Linnean Society of London》2011,166(3):282-300
China is one of the richest countries for plant diversity with approximately 33 000 vascular plant species, ranking second in the world. However, the plant diversity in China is increasingly threatened, with an estimated 4000–5000 plant species being threatened or on the verge of extinction, making China, proportionally, one of the highest priorities for global plant biodiversity conservation. Coming in the face of the current ecological crisis, it is timely that China has launched China's Strategy for Plant Conservation (CSPC). China has increasingly recognized the importance of plant diversity in efforts to conserve and sustainably use its plant diversity. More than 3000 nature reserves have been established, covering approximately 16% of the land surface of China. These natural reserves play important roles in plant conservation, covering more than 85% of types of terrestrial natural ecosystems, 40% of types of natural wetlands, 20% of native forests and 65% of natural communities of vascular plants. Meanwhile, the flora conserved in botanical gardens is also extensive. A recent survey shows that the 10 largest botanical gardens have living collections of 43 502 taxa, with a total of 24 667 species in ex situ conservation. These provide an important reserve of plant resources for sustainable economic and social development in China. Plant diversity is the basis for bioresources and sustainable utilization. The 21st century is predicted to be an era of bio-economy driven by advances of bioscience and biotechnology. Bio-economy may become the fourth economy form after agricultural, industrial, and information and information technology economies, having far-reaching impacts on sustainable development in agriculture, forestry, environmental protection, light industry, food supply and health care and other micro-economy aspects. Thus, a strategic and forward vision for conservation of plant diversity and sustainable use of plant resources in the 21st century is of far-reaching significance for sustainable development of Chinese economy and society. 相似文献

South Africa, as a megadiverse country (±21 700 vascular plants, 4800 vertebrates and 68 900 invertebrates described), is presently engaged with an extended, modified Global Strategy for Plant Conservation (GSPC). The country is fortunate in having a strong tradition of systematics research and, inter alia, houses several million preserved plant specimens (±1 million databased and georeferenced), allowing taxonomists and conservationists to track both the occurrence and distribution of indigenous and naturalized plant species. These rich local resources have been extensively drawn upon to deliver, with varying degrees of success, the 16 outcome-oriented GSPC 2010 Targets. The National Environmental Management: Biodiversity Act (NEMBA, 2004), the National Biodiversity Strategy and Action Plan (NBSAP) and the National Biodiversity Framework (NBF) have provided a robust legislative, enabling and policy framework for making operational and advancing GSPC-related efforts. However, within an emerging economy, the conservation of biodiversity has competed for government resources with housing, sanitation, primary education, basic health care and crime prevention, delivery of which translates to the currency of politicians: votes. A key challenge identified by local (and global) biodiversity scientists for the current GSPC phase is broad-scale advocacy, communicating the changing state of nature, and the inter-relatedness of biodiversity and human well-being. The nature of meeting this challenge is explored. 相似文献

The contribution of the European Native Seed Conservation Network (ENSCONET, 2004-2009) and the ENSCONET Consortium (since 2010) towards meeting the 2020 Global Strategy for Plant Conservation (GSPC) target 8 was assessed in 2017. While the outcome was positive (62.7% of European threatened species already conserved ex situ in seed banks), the analysis showed that it was essential to provide guidance on which European native threatened species should be collected as a priority if the target was to be reached by 2020. In this paper we present a priority-setting method and its result, designed to guide collecting strategies across Europe to meet the 2020 GSPC target 8. The result of our study is a country-based checklist of European threatened taxa to be collected and stored ex situ across the seed banks of the ENSCONET Consortium by 2020. After discussing the results of the applied method, the ENSCONET Consortium Steering Committee has identified some key action points to support the implementation of such a collecting strategy across Europe in order to meet the 2020 GSPC target 8 for Europe. 相似文献

Evidence-based assessments of extinction risk are established tools used to inform the conservation of plant species, and form the basis of key targets within the framework of the Global Strategy for Plant Conservation (GSPC). An overall picture of plants threat assessments is challenging due to the use of a variety of methodologies and range in scope from global to subnational. In this study, we quantify the state of progress in assessing the extinction risk of all land plants, determine the key geographic and taxonomic gaps with respect to our understanding of plant extinction risk, and evaluate the impact of different sources and methodologies on the utility of plant assessments. To this end, we have analyzed a cleaned dataset compiled from IUCN Red List of Threatened Species and Regional Red Lists. We reveal that there are assessments available for 89,810 distinct species or 25% of all accepted land plant species. However unlike with other major organismal lineages the bulk of the plant species assessments are derived from Regional Red Lists, and not the Global IUCN Red List. We demonstrate that this bias towards regional assessments results in distinct taxonomic and geographic strengths and weaknesses, and we identify substantial taxonomic and geographic gaps in the assessment coverage. With species that have been assessed in common at both global and regional levels, we explore the implications of combining threat assessments from different sources. We find that half of global and regional assessments do not agree on the exact category of extinction risk for a species. Regional assessments assign a higher risk of extinction; or underestimate extinction risk with almost equal frequency. We conclude with recommended interventions, but support the suggestion that all threat assessments should be pooled to provide more data and broaden the scope of threat assessments for monitoring progress towards GSPC targets. 相似文献

International agreements and policies play an increasingly prominent role in strategies to combat biodiversity loss. However,
conservation policies can only have a conservation impact if implemented. Identifying factors determining the influence of
a policy on institutions could improve the process of policy development and communication. We examine how and why botanic
gardens have responded to the first phase of a global conservation policy (the Global Strategy for Plant Conservation GSPC)
using quantitative (questionnaires completed by 255 botanic gardens in 67 countries) and qualitative (in-depth interviews
with five gardens in five countries) methods. We found that while the majority of gardens were aware of the GSPC, older gardens
in the global north, and younger global south gardens are most influenced by the GSPC. Gardens that are members of a global
botanic garden network and gardens with larger budgets are implementing more targets. Targets implemented tend to be aligned
with existing institutional aims. Gardens highlighted an absence of a mechanism to feedback successes and failures. The GSPC
has recently been reviewed and new targets for the period of 2011–2020 developed. To widen the influence of the GSPC, dissemination
should include guidelines on how institutions could implement the policy, with particular focus on influencing younger global
north gardens and older global south gardens. There are plans to develop a toolkit to help gardens better understand and implement
the GSPC. We recommend the toolkit include a system for GSPC implementers to communicate with each other and to feedback to
policy formulators. 相似文献

The need for action on the global environment is now well understood and governments, agencies, non-governmental organizations and botanic gardens have all been working in their various ways to promote environmental sustainability and reduce species and habitat loss for at least 10–20 years. The Global Strategy for Plant Conservation (GSPC) has been widely adopted, particularly by the botanic garden community, and has resulted in many successes despite failing to achieve its ultimate goal of halting the loss of plant biodiversity. The objectives and targets for Phase 2 of the GSPC, running from 2010 to 2020, mirror those of Phase 1 and had been largely agreed prior to their formal adoption at the Conference of the Parties to the Convention on Biological Diversity in Nagoya in October 2010. However, to be successful, the scientific contribution of botanic gardens needs to be strengthened, as does government policy and commitment. Botanic garden research to underpin conservation action, including the role of botanic garden horticulture, training and international capacity building, has a major part to play and needs to be better understood and better coordinated. We provide examples based on the experience of the Royal Botanic Garden Edinburgh in the UK and overseas. Government policy, at national and international levels, needs to reflect the fundamental importance of plant diversity in maintaining the biosphere and supporting humanity. The commitment of significant new resources is an essential prerequisite for success, but this needs to be well coordinated, inclusive of all stakeholders and carefully targeted. A further challenge is the need to integrate better the plant diversity-related activities of what are currently diverse and disconnected sectors, including agriculture, forestry, protected area management and botanic gardens. 相似文献
