Modelling Woodpecker Damage in Wooden Utility Pole Systems across the Southeast United States

*Hannah Chelsea WRIGHT, Scott A RUSH(Mississippi State University)

Woodpecker activity in utility poles and subsequent costs to repair and replace these structures have been an ongoing source of wildlife-human conflict in the U.S. during the last 100 years. In the southeast United States, the Tennessee Valley Authority utility company has accrued an estimated $5 million dollar/year in costs through mitigation of woodpecker damage. With the goal of reducing the annual cost to the utility providers, we will be using species occurrence records spanning 475,000 km^2 of utility pole systems that have been affected by various woodpecker species. We are working to identify features (abiotic and biotic) associated with areas of heightened woodpecker damage through the use of an Ensemble Species Distribution Model and paralleling this with a Multi-State Occupancy Model. Using information obtained from these models, we will identify areas that are associated with the highest woodpecker activity and thus likely to accrue damage to the utility infrastructure. This ongoing work has the objective of recommending areas of increased surveillance due to landscape characteristics associated with dense clusters of woodpecker damage to allow mitigation tactics to be implemented before the power system is affected.
