保护区是保护生物多样性免受日益严重的人为威胁的一个关键工具。作为《2011-2020年生物多样性战略计划》的签署国，196个国家承诺支持扩大全球保护区的范围和保护区管理的质量。虽然这导致保护区指定数量大幅增加，但许多保护区缺乏保证有效保护生物多样性所需的资源。使用管理报告从2167 PA（面积占全球陆地PA房地产的23%），我们表明，这些PA报告中只有不到四分之一的人员配备和预算方面有足够的资源。利用与我们的保护区样本重叠的11，919种陆生脊椎动物物种的地理范围数据，我们估计只有4-9%的陆生两栖动物，鸟类和哺乳动物在现有的全球保护区范围内得到充分的代表，当只考虑资源充足的保护区时。虽然继续扩大世界保护区是必要的，但将重点从数量转向质量对于有效应对当前的生物多样性危机至关重要。
Protected areas (PAs) are a key tool in efforts to safeguard biodiversity against increasing anthropogenic threats. As signatories to the 2011-2020 Strategic Plan for Biodiversity, 196 nations pledged support for expansion in the extent of the global PA estate and the quality of PA management. While this has resulted in substantial increases in PA designations, many sites lack the resources needed to guarantee effective biodiversity conservation. Using management reports from 2167 PAs (with an area representing 23% of the global terrestrial PA estate), we demonstrate that less than a quarter of these PAs report having adequate resources in terms of staffing and budget. Using data on the geographic ranges of the 11,919 terrestrial vertebrate species overlapping our sample of PAs, we estimate that only 4-9% of terrestrial amphibians, birds, and mammals are sufficiently represented within the existing global PA estate, when only adequately resourced PAs are considered. While continued expansion of the world's PAs is necessary, a shift in emphasis from quantity to quality is critical to effectively respond to the current biodiversity crisis.
