In late 2020, governments will set the next decade of conservation targets under the UN Convention on Biological Diversity. Setting new targets requires understanding how well national protected area (PA) networks are spatially representing important areas for biodiversity and ecosystem services. We analyzed the representation of biodiversity priority areas (BPAs), forests, forest carbon stocks, non-timber forest products (NTFPs), and freshwater ecosystem services (FES) within terrestrial PA systems in Cambodia, Guyana, Liberia, Madagascar, and Suriname in 2003 and 2017. Four of the countries (all except Suriname) expanded their terrestrial PA networks during the study period. In all five countries, we found that PAs represented BPAs, forests, and forest carbon stocks relatively well, based on their size. PAs did not represent NTFPs and FES particularly well, except in Cambodia where FES were well represented. Countries that expanded PA networks during the study period also increased representation of forests, BPAs, and ES; in Cambodia and Madagascar these increases were substantial. Representation could be improved across all five countries, however, indicating that additional efforts are needed to safeguard biodiversity and ecosystem benefits to people in these countries.

2020年末，各国政府将根据《联合国生物多样性公约》制定下一个十年的保护目标。设定新目标需要了解国家保护区网络在空间上如何代表生物多样性和生态系统服务的重要领域。我们分析了柬埔寨，圭亚那，利比里亚，马达加斯加和苏里南的陆地PA系统内生物多样性优先区（BPA），森林，森林碳储量，非木材森林产品（NTFP）和淡水生态系统服务（FES）的代表性。 2003年和2017年。在研究期间，其中四个国家（苏里南除外）均扩展了其地面PA网络。在所有五个国家/地区中，我们发现，PA代表了BPA，森林和森林碳储量，基于它们的规模，它们相对较好。巴勒斯坦权力机构没有很好地代表NTFP和FES，除了在柬埔寨，FES的代表很好。在研究期间扩大了保护区网络的国家还增加了森林，双酚A和ES的代表性；在柬埔寨和马达加斯加，这些增长是可观的。但是，这五个国家的代表人数都可以增加，这表明需要作出更多的努力来保护这些国家人民的生物多样性和生态系统利益。
