This project aims to document historical changes in the spatial grain of the patch burning mosaic in an Arnhem Land savannah with an unbroken history of management by Aboriginal people, and in adjacent areas where traditional management has ceased. The mosaic's spatial grain will be inferred by mapping the individual ages of the long-lived conifer Callitris intratropica. Prior research has shown that Callitris individuals can be reliably aged, and population structures are very sensitive to fire regimes: saplings only establish if unburnt for 10 years. This research is expected to provide the first direct test of the hypothesis that Aboriginal people maintained fine-grained fire mosaics in savannas, and inform bushfire policy debates.

该项目旨在记录阿纳姆地大草原上的补丁燃烧马赛克的空间纹理的历史变化，该大草原具有土著人管理的完整历史，以及传统管理已经停止的邻近地区。马赛克的空间纹理将通过绘制长寿的针叶树Callitris intratropica的个体年龄来推断。先前的研究表明，马蹄莲个体可以可靠地老化，种群结构对火灾非常敏感：树苗只有在10年未被烧毁的情况下才能建立。这项研究预计将提供第一个直接测试的假设，原住民保持细粒度的火马赛克在热带稀树草原，并告知森林防火政策的辩论。
