Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, both at patch and landscape scales. We will develop an optimization framework incorporating models of vegetation maturation and biotic responses to aid designs for placement and scheduling of replantings to give the best outcomes for biodiversity management given constraints on amounts of retired area and costs of implementation.

土壤和水的问题以及本地生物多样性的下降与本地植被的清除有关。我们认为，未来的景观与更多的原生植被比现在处理这些自然资源问题。植物将缓慢成熟，因此景观重新植被的最佳规划必须考虑新的植被需要多长时间才能在斑块和景观尺度上提供合适的栖息地。我们将开发一个优化框架，将植被成熟和生物反应的模型，以援助的安置和安排补种的设计，以提供最好的结果，为生物多样性管理的退休面积和实施成本的限制。
