Overview
The Global Strategy for Plant Conservation (GSPC) set an ambitious target to achieve a conservation assessment for all known plant species by 2020. We consolidated digitally available plant conservation assessments and reconciled their scientific names and assessment status to predefined standards to provide a quantitative measure of progress toward this target. The 241,919 plant conservation assessments generated represent 111,824 accepted land plant species (vascular plants and bryophytes, not algae). At least 73,081 and up to 90,321 species have been assessed at the global scale, representing 21-26% of known plant species. Of these plant species, at least 27,148 and up to 32,542 are threatened. Eighty plant families, including some of the largest, such as Asteraceae, Orchidaceae, and Rubiaceae, are underassessed and should be the focus of assessment effort if the GSPC target is to be met by 2020. Our data set is accessible online (ThreatSearch) and is a baseline that can be used to directly support other GSPC targets and plant conservation action. Although around one-quarter of a million plant assessments have been compiled, the majority of plants are still unassessed. The challenge now is to build on this progress and redouble efforts to document conservation status of unassessed plants to better inform conservation decisions and conserve the most threatened species. La Estrategia Global para la Conservación de Plantas (GSPC, en inglés) estableció el objetivo ambicioso de lograr una evaluación de la conservación para todas las plantas conocidas para el año 2020. Consolidamos evaluaciones sobre la conservación de plantas disponibles digitalmente y reconciliamos sus nombres científicos y estados de evaluación con los estándares predefinidos para proporcionar una medida cuantitativa del progreso hacia este objetivo. Las 241,919 evaluaciones generadas sobre la conservación de las plantas representan a 111,824 especies aceptadas de plantas terrestres (plantas vasculares y briofitas, algas no). Al menos 73,081 y hasta 90,321 especies han sido evaluadas a escala global, representando 21 - 26% de las especies de plantas conocidas. De estas especies de plantas, al menos 27,148 y hasta 32,542 están amenazadas. Ochenta familias de plantas, incluidas algunas de las más grandes como Asteraceae, Orchidaceae, y Rubiaceae están sub-evaluadas y deberían ser el foco del esfuerzo de evaluación si se quiere alcanzar el objetivo de la GSPC para el año 2020. Nuestro conjunto de datos está disponible en línea (ThreatSearch) y es una línea de base que puede usarse para apoyar directamente a otros objetivos de la GSPC y de las acciones de la conservación de plantas. Aunque se han recopilado alrededor de un cuarto de millón de evaluaciones sobre plantas, la mayoría de las plantas permanecen sin ser evaluadas. El reto ahora es construir sobre este progreso e intensificar los esfuerzos para documentar los estados de conservación de las plantas sin evaluación para informar de mejor manera las decisiones de conservación y conservar a la mayoría de las especies amenazadas. 全球植物保护战略(GSPC)设立了ー个雄心勃勃的目标, 要在2020年前对所有已知植物物种进行保护评 估。我们整合了数字化的植物保护评估, 并按照预设标准整理了它们的学名和评估状况,从而为这一目标的进 展提供了量化标准。所产生的241,919个植物保护评估代表了 111,824种公认的陆生植物(维管植物和苔藓,不 包括藻类) 。73,081—90,321个物种有全球水平的评估, 它们代表着21-26%的已知植物物种。在这些植物中,27,148-32,542个物种是受威胁物种。80个科的植物,包括一些如菊科、兰科和茜草科等最大的科,受到的保护 评估仍不足;如果要达到GSPC定下的2020年目标,这些科应该作为未来评估工作的重点。我们的数据集可以在 线获取(ThreatSearch),并可以用作直接支持其它GSPC目标和植物保护行动的基准。尽管ー百万份植物评估已 经编制了约四分之一,但大部分的植物仍没有得到评估。当前的挑战是,在目前进展的基础上加倍努力记录未评 估植物的保护状況,从而更好地为保护决策和保护最濒危的物种提供支持。
