We need to know how different prescribed burning regimes set the stage for long-term changes in plant community composition, diversity, and flammability. This project aims to reveal how plant community dynamics under different fire scenarios can be predicted based on contemporary interactions between plants and soil micro-organisms. This innovative approach to fire ecology integrates soil biology and plant ecophysiology with sophisticated experiments and novel modelling techniques. Expected outcomes include a much-needed mechanistic framework for early detection of major ecological changes under novel fire regimes, with direct benefits for land managers and the long-term conservation of Australia’s iconic vegetation.

我们需要知道不同的规定燃烧制度如何为植物群落组成、多样性和可燃性的长期变化奠定基础。本项目旨在揭示如何基于植物与土壤微生物之间的当代相互作用来预测不同火灾情景下的植物群落动态。这种创新的方法来火生态学整合土壤生物学和植物生态生理学与复杂的实验和新颖的建模技术。预期的结果包括一个急需的机制框架，用于在新的火灾制度下早期发现主要的生态变化，这对土地管理者和澳大利亚标志性植被的长期保护有直接的好处。
