Developing a framework for restoration
Restoration aims to repair ecosystem functioning and replace biological components that have suffered losses or local extinction. A restoration model is the framework that describes in detail the desired physical, chemical, and biological attributes of the restored ecosystem. While the model should be site-specific, its attributes should also
fulfill regional restoration needs. Developing a model that, when implemented, would enhance biodiversity and functioning at both local and regional scales requires an understanding of the opportunities and constraints present at the site, as well as the region. This chapter describes how these constraints and opportunities can be identified using a variety of information sources — historical, regional, and on-site. The significance of natural variation (spatial and temporal) in ecological restoration is highlighted, and ways of accommodating topographic heterogeneity in a dynamic restoration model and long-term restoration strategy are considered. Lastly, the steps involved in the development of a detailed restoration plan that takes an adaptive management approach are outlined.
