与未来十年保护30%的陆地和海洋（“30x30”）的国际运动相一致，美国已承诺到2030年将其目前的保护土地面积增加一倍以上。虽然公有和管理的保护区是过去世纪划区养护的基石，但建立这种土地的成本很高，而且保护对生物多样性养护和减缓气候变化具有最高价值的地区的能力有限。在这里，我们研究了私人土地在美国联邦和州两级达到30x30保护目标的当前和潜在贡献。我们发现，与公有和管理的保护地相比，受保护的私人土地（保护地役权）更经常被指定为高保护优先级的地区，拥有显着更高的平均物种丰富度，并封存更脆弱的单位面积陆基碳。这些和相关的调查结果突出表明，有必要建立机制，让私人土地所有者参与持久的保护伙伴关系。
Coincident with international movements to protect 30% of land and sea over the next decade ( "30x30 "), the United States has committed to more than doubling its current protected land area by 2030. While publicly owned and managed protected areas have been the cornerstone of area-based conservation over the past century, such lands are costly to establish and have limited capacity to protect areas of the highest value for biodiversity conservation and climate change mitigation. Here we examine the current and potential contributions of private land for reaching 30x30 conservation targets at both federal and state scales in the United States. We find that compared to publicly owned and managed protected lands, protected private lands (conservation easements) are more often in areas designated as high conservation priority, hold significantly higher mean species richness, and sequester more vulnerable land-based carbon per unit area. These and related findings highlight the necessity of mechanisms that engage private landholders in enduring conservation partnerships.
