Many landscapes around the world have been effectively denuded of natural vegetation, causing precipitous declines in native biodiversity. Mitigation of such effects in the near/medium-term future requires substantial ecological advice. We will employ our skills developed in modelling distributions of species across landscapes based on terrain, soils and climate to assess alternative landscape-reconstruction scenarios. This links use of existing data sets for initial modelling, a validation phase for testing model reliability and for refining models, and a subsequent GIS-based modelling phase in which alternative options for reconstructing landscapes are evaluated for their effectiveness in sustaining landscape-scale native biodiversity.

世界各地许多景观的自然植被已被有效剥夺，导致本地生物多样性急剧下降。在近期/中期减轻此类影响需要大量的生态建议。我们将利用我们在基于地形、土壤和气候的景观物种分布建模中所开发的技能来评估替代的景观重建情景。这将使用现有数据集进行初始建模、测试模型可靠性和完善模型的验证阶段以及随后的基于 GIS 的建模阶段联系起来，在该阶段中评估重建景观的替代方案在维持景观规模本地生物多样性方面的有效性。
