Ranking transportation structures by their potential to facilitate wildlife passage

As featured in the November 29, 2021 Research and Innovation Newsletter: Understanding the connectivity value of transportation structures can help minimize impacts on Vermont's wildlife.

Brief Project Description: We assessed the connectivity value of transportation structures in Vermont according to predicted wildlife movement patterns and structure characteristics. Our approach used electrical circuit theory to model the movement of wildlife across Vermont and around transportation structures, based on wildlife occurrence data and landscape features. This information was incorporated into a linear programming decision-making framework along with structure attributes to rank each transportation structure at two spatial scales. Results provide insight into the connectivity value of structures and inform decision-making to mitigate the effects of roads on wildlife. This project is a collaboration between VTrans, The Nature Conservancy, Vermont Fish & Wildlife Department, and University of Vermont.
