This project aims to predict the biodiversity consequences of a global trend of increasing woody cover in tropical savannas. Believed to be driven by a combination of elevated atmospheric CO2 concentration, climate change and management actions including fire suppression and cattle grazing. Expected outcomes are the integration of a range of modelling approaches to predict long-term impacts of environmental change on savanna biodiversity and the identification of land-use and management strategies to best mitigate these impacts. Likely benefits are an improved understanding of trade-offs between alternative land-uses in the savannas, including biodiversity conservation, fire management for carbon credits, and cattle grazing.

该项目旨在预测热带稀树草原树木覆盖增加的全球趋势对生物多样性的影响。据信是由大气中二氧化碳浓度升高、气候变化和包括灭火和放牧在内的管理行动共同驱动的。预期的结果是整合一系列建模方法，以预测环境变化对稀树草原生物多样性的长期影响，并确定土地利用和管理战略，以最好地减轻这些影响。可能的好处是更好地理解稀树草原上不同土地用途之间的权衡，包括生物多样性保护、碳信用的火灾管理和放牧。
