Fire, termites and tree hollows in an Australian tropical savanna

Data from study of tree hollows and long-term fire regimes in a tropical savanna near Darwin, Australia. Data was collected at a long-term (18-year) fire experiment approximately 40 km south of Darwin. Includes information on number of tree hollow entrances, proportion of stem piping at 0.2 m and 1.3 m, tree diameter at breast height, termite abundance (number of encounters) and level of activity (proportion of bait consumed), as well as fire regime (early dry season burns every one, two, three and five years, late dry season burn every two years, and unburned) and level of fire activity (accumulated fire intensity values over all years of burning).\nLineage: Data was collected in 2022 at a long-term fire experiment using a combination of termite surveys, drone-based hollow surveys and stem piping surveys (refer to publication for more details).\n\nRochelmeyer, E., Murphy, B.P., Levick, S.R., Stobo-Wilson, A.M., Richards, A.E., (2025).

本数据集源自澳大利亚达尔文市周边热带稀树草原的树洞与长期火制度研究。数据采集于达尔文市南约40公里处的一项为期18年的长期火实验，涵盖以下指标：树洞入口数量、0.2米与1.3米处的茎干中空（stem piping）率、树胸径（tree diameter at breast height）、白蚁丰度（相遇次数）与活动水平（饵料消耗比例），同时包含火制度信息（每年、每两年、每三年及每五年开展的旱季早期火烧，每两年开展的旱季晚期火烧，以及未火烧对照组）与火活动水平（所有燃烧年份的累计火强度值）。
数据谱系：本数据集于2022年通过白蚁调查、无人机树洞调查与茎干中空调查相结合的方式，在上述长期火实验中采集完成，详细信息请参阅相关出版物。
