自20世纪70年代以来，美国西部的野火活动一直在增加，许多火灾发生在政府机构管理的土地上。超过600万英亩的公共土地被私人土地包围，缺乏道路通道，使它们在法律上无法进入联邦和州机构，并可能限制野火的管理和扑灭。在本文中，我们收集了1992-2015年期间美国西部公共土地上发生的所有火灾的数据，并估计了法律的可及性对火灾规模的影响。我们发现，点火是14%-23%更有可能成为大（大于一英亩），如果他们发生在难以接近的土地。我们提供的证据表明，这种影响可能部分是由机构无法进行燃料管理，部分是由法律上无法进入的土地上的镇压反应较慢。我们的研究结果表明，野火的预防和抑制可以通过改善对公共土地的使用来加强，并强调需要对土地所有权和野火之间的关系进行持续的研究。
Wildfire activity in the western United States has been increasing since the 1970s, with many fires occurring on land managed by government agencies. Over six million acres of public lands are surrounded by private land and lack road access, making them legally inaccessible to federal and state agencies and potentially constraining management and suppression of wildfires. In this paper, we assemble data on all fires that started on public lands in the western US over the period 1992–2015 and estimate the effect of legal accessibility on fire size. We find that ignitions are 14%–23% more likely to become large (greater than one acre) if they occur on inaccessible land. We provide evidence that this effect may be driven in part by agencies’ inability to conduct fuels management and in part by slower suppression responses on legally inaccessible land. Our results suggest that wildfire prevention and suppression could be bolstered by improved access to public lands and underscore the need for ongoing research on the relationship between land ownership and wildfire.
