Scenario Analysis with Performance Indicators: a Case Study for Forest Linkage Restoration

Regional conservation programs have as a goal the integration of protected areas into broader ecological networks. Creating landscape corridors and buffers within a land mosaic is one way to support the functional viability of landscapes. Implementing these programmes on the ground is problematic, however, especially in areas with a mix of land uses and fragmented forests. In such cases it is necessary to prioritise restoration decisions to balance the benefits against the cost of restoration efforts. We approach this as a planning problem to work with stakeholders to explore options that find a balance between the environmental benefits and costs. The options are mapped onto the landscape as scenarios and then evaluated in a GIS planning support system. This chapter describes a methodology for prioritising restoration efforts and applies this to a hypothetical study for northern Australia. Spatial indicators are used to assess alternate options for vegetation corridors linking forest remnants. The indicators mainly measure spatial structure, but also aim to incorporate knowledge on provision of landscape ecological functions. The indicators assess both site level and landscape benefits. Diagnostic spatial indicators and scenarios are developed generically within GIS so the approach may be tuned to different applications and planning problems.
