Against a background of continuing loss of biodiversity, it is argued that for the successful conservation of threatened plant species we need to ensure the more effective integration of the various conservation actions employed, clarify the wording of the CBD targets and provide clearer operational guidance as to how they are to be implemented and their implementation monitored. The role and effectiveness of protected areas in conserving biodiversity and in particular plant species are discussed as are recent proposals for a massive increase of their extent. The need for much greater effort and investment in the conservation or protection of threatened species outside protected areas where most plant diversity occurs is highlighted. The difficulties involved in implementing effective conservation of plant diversity both at an area- and species/population-based level are discussed. The widespread neglect of species recovery for plants is noted and the desirability of making a clearer distinction between species recovery and reintroduction is emphasized. Key messages from a global overview of species recovery are outlined and recommendations made, including the desirability of each country preparing a national species recovery strategy. The projected impacts of global change on protected areas and on species conservation and recovery, and ways of addressing them are discussed.
在生物多样性持续丧失的背景下,有人认为,为了成功保护受威胁植物物种,我们需要确保更有效地整合所采用的各种保护行动,明确《生物多样性公约》目标的措辞,并就如何实施这些目标以及如何监测其实施情况提供更清晰的操作指南。讨论了保护区在保护生物多样性特别是植物物种方面的作用和有效性,以及最近大幅扩大其范围的提议。强调了在大多数植物多样性所在的保护区之外,需要在保护或养护受威胁物种方面付出更大努力和投入。讨论了在基于区域和基于物种/种群的层面实施有效植物多样性保护所涉及的困难。指出了对植物物种恢复的普遍忽视,并强调了更明确区分物种恢复和重新引入的可取性。概述了全球物种恢复概况的关键信息并提出了建议,包括每个国家制定国家物种恢复战略的可取性。讨论了全球变化对保护区以及物种保护和恢复的预计影响,以及应对这些影响的方法。
