Abstract

Using a Return on Investment Approach to Prioritize Habitat Restoration
Track: Ecology and Conservation
Authors: Jutta Burger, Yi-Chin Fang

Ecological restoration is an expensive, time-intensive process that requires complex decision-making and involves multiple variables, such as when and where to restore, which methodologies to apply, and how much money to invest. Using a decision-theoretic framework, we develop a spatially and temporally explicit prioritization model that accounts for: 1) cost of restoration, 2) likelihood of success, 3) probability of a catastrophic fire, and 4) benefit in terms of area restored, spatial connectivity, and relative contribution of a site toward landscape-scale ecological resilience. We explore the sensitivity of our results to uncertainties in key parameters and compare restoration schedules under alternative benefit functions to demonstrate trade-offs associated with different objectives and assumptions. Our prioritization model demonstrates time and resource efficiency to managers and provides a transparent and adaptable decision-making process. The resulting Return on Investment framework can be adapted temporally to changing conditions and be applied to any protected landscape.
