这项研究评估了热带保护区对森林砍伐火灾的影响，这是在一个很好的空间尺度上森林砍伐的最佳全球一致的代理。该文件涵盖了整个热带森林生物群落，以估计数千个保护区所避免的森林砍伐。在最新进展的基础上，作者使用匹配方法将保护区点与类似的未受保护点进行比较，控制坡度，降雨量，道路接近度以及影响森林砍伐和保护区位置的其他因素。与以前的研究不同，这项工作提供了一个持续的措施，以衡量保护的有效性，作为不同程度的毁林压力的函数，以及不同类别的保护（严格、多用途和土著）。
This study assesses the impact of tropical protected areas on deforestation fires, which are the best available globally consistent proxy for deforestation at a fine spatial scale. The paper covers the entire tropical forest biome to estimate the avoided deforestation afforded by several thousand protected areas. Building on recent advances, the authors use matching methods to compare protected area points with similar unprotected points, controlling for slope, rainfall, road proximity, and other factors affecting both deforestation and protected area placement. Unlike previous studies, this work provides a continuous measure of the effectiveness of protection as a function of varying degrees of deforestation pressure, as well as for different classes of protection (strict, multi- use and indigenous).
