摘要
Safeguarding Earth's tree 多樣性 is a conservation priority due to the importance of trees for 生物多樣性 and ecosystem functions and services such as carbon sequestration. Here, we improve the foundation for effective conservation of global tree 多樣性 by analyzing a recently developed database of tree 物種 covering 46,752 物種. We quantify range protection and anthropogenic pressures for each 物種 and develop conservation priorities across taxonomic, 系統發育, and functional 多樣性 dimensions. We also assess the effectiveness of several influential proposed conservation prioritization frameworks to protect the top 17% and top 50% of tree priority areas. We find that an average of 50.2% of a tree 物種' range occurs in 110-km grid cells without any protected areas (PAs), with 6,377 small-range tree 物種 fully unprote
