To define the elements of analysis that can be used to systematically predict, assess, and minimize road impacts on ecosystem services across multiple spatial scales. These elements also serve as the foundation for focusing monitoring efforts on those areas most likely to experience the greatest change in ecosystem processes and, similarly, target mitigation to areas with the greatest potential for recovery.
Type of Study:
Element 1: Identify Direct Effects Element 2: Describe Important Spatial Interactions (Among Units and Groups of Units). Element 3: Define Indirect Effects, Including Process Feedbacks. Element 4: Define Interactions with Other Stressors Element 5: Consider Spatial Variability of Responses to Roads Associated with Differences in Soils, Ecological State (Including Plant Community and Soil Quality), and Landscape Position. Element 6: Consider Thresholds and Other Nonlinear Dynamics that Occur with Increasing Road Density or Length (Cumulative Effects).
