Emerald Ash Borer Cooperative Management: Ideal and in-practice

May 9, 2018
Robert Haight, USDA Forest Service Jeff Hafner, Rainbow Treecare

The emerald ash borer (EAB) is one of the most economically and environmentally damaging invasive species to reach the United States. Economic damage of EAB is most severe in cities that lose abundant high-value ash trees growing along streets and in yards. Pest management and economic models suggest that a landscape level approach across all ownerships, including surveillance for early detection, treatment of ash trees with systemic insecticides, and removal of infested ash trees, yields the greatest benefits at the lowest costs. While individual cities can develop EAB management plans that include these measures on public lands, they cannot manage beyond their borders and may not realize maximum benefit. In this webinar, Robert Haight will present research on the economics of ash treatment and removal strategies and the potential gains in social welfare from the ideal cooperation among city governments and private residents. Based on years of experience, Jeff Hafner will describe barriers to direct cooperation among cities and practices that professional arborists can use to overcome those barriers. He will share examples of management plans and agreements that he has brokered among cities and private residents in the Twin Cities metropolitan area.

Resources Mentioned in the Webinar

Cost of Potential Emerald Ash Borer Damage in U.S. Communities, 2009-2019
Published in Ecological Economics, this article estimates the discounted cost of ash treatment, removal, and replacement on developed land in a 25-state study area.

Evaluation of Potential Strategies to SLow Ash Mortality (SLAM) Caused by Emerald Ash Borer (Agrilus planipennis): SLAM in an urban forest
This article from the International Journal of Pest Management describes a study that uses spatially explicit simulations to evaluate the potential of a recently developed systemic insecticide to protect ash.

A Bioeconomic Analysis of an Emerald Ash Borer Invasion of an Urban Forest with Multiple Jurisdictions
This article, published in Resource and Energy Economics, suggests that centralizing the budget across jurisdictions does more to increase total net benefits from emerald ash borer control than increasing any one municipal budget.

Cooperative Management of Invasive Species: A dynamic Nash bargaining approach
Published in Environmental and Resource Economics, this study examines the scope for bargaining in invasive species problems where spread depends on the employment of costly controls.

Research on Invasive Species Management Strategies
Robert Haight provides links to his research on invasive species control and how to allocate scarce resources among management strategies.

Emerald Ash Borer Information Network
A collaborative effort of the USDA Forest Service and Michigan State University, this website provides comprehensive, accurate, and timely information on the emerald ash borer. Check out the EAB University for additional webinars.
