Forest fires are powerful agents of ecological change, linked to the amounts and types of fuels as well as to climate patterns such as the El Nino-Southern Oscillation (ENSO) and Pacific Decadal and Atlantic Oscillations. This project is an international collaboration with Mexican scientists Jose Villanueva-Diaz and Eladio Cornejo-Oviedo. A new network of long-term fire and climate chronologies will be developed together with analyses of fuel dynamics in northern Mexico. Unique relict sites that are among the least perturbed by modern human impacts, will be a key part of the chrono-sequences to be established. The study will reconstruct fire regimes for the past about 300 years using fire-scarred trees. Climate variables will be determined through tree-ring analysis and from data collected by field instruments, and forest structure will be directly measured. The research will benefit both Mexico and the United States. Funding will support graduate and undergraduate students from both countries. In addition to scientific publications, the results will be interpreted and transferred to decision makers, including landowners, managers, and conservation organizations. The findings will increase understanding of the fuel and climate factors that regulate fire regimes and of how fire patterns might change in the future. They will have immediate relevance for conservation strategies in the biologically diverse forests of northern Mexico and the southwestern U.S.

森林火灾是生态变化的强大因素，与燃料的数量和类型以及厄尔尼诺-南方涛动（ENSO）和太平洋十年期和大西洋涛动等气候模式有关。 该项目是与墨西哥科学家Jose Villanueva-Diaz和Eladio Cornejo-Oviedo的国际合作。将开发一个新的长期火灾和气候年表网络，同时分析墨西哥北方的燃料动态。受现代人类影响最小的独特遗迹将是建立时间序列的关键部分。 这项研究将利用火灾后留下疤痕的树木重建过去约300年的火灾状况。 将通过树木年轮分析和实地仪器收集的数据确定气候变量，并将直接测量森林结构。 这项研究将使墨西哥和美国受益。 资金将支持两国的研究生和本科生。 除了科学出版物，研究结果将被解释并传递给决策者，包括土地所有者，管理者和保护组织。 这些发现将增加对调节火灾制度的燃料和气候因素以及未来火灾模式可能如何变化的理解。 它们将对墨西哥北方和美国西南部生物多样性森林的保护战略具有直接的意义。
