Conceptual frameworks and references for landscape-scale restoration : reflecting back and looking forward

Abstract

We review some of the most commonly known models in restoration ecology from the past 20 years. From these, we seek to identify essential elements required for the scaling-up and mainstreaming of restoration and, based on that, develop a new framework that could be used to assist in the realization of long-lasting and effective restoration policies and programs at the landscape and larger spatial scales. We argue that the reference model is particularly important at a time when there are urgent calls and investments for scaling-up restoration to the landscape scale. At that scale, we argue, it is essential to consider both ecological restoration and ecological rehabilitation as just two of the various components in a ‘‘family’’ of restorative activities that must be deployed, including changed management practices for agriculture, to make ongoing human activities and land uses more ecologically sound and sustainable. In conclusion, we present a new model that could help orient if not actually design planning, monitoring and evaluation, scaling-up, and applying restorative activities in new areas.
