Abstract

Spread of emerald ash borer (Agrilus planipennis Fairmaire, EAB) in the United States has been rapid and extensive. Nearly 10 years after its initial detection near Detroit, Michigan, EAB is now found in 15 states spanning a radius greater than 500 miles. While human activity has been central to facilitating the spread of EAB over long distances, the role of landscape pattern is not well understood. The purpose of this study was to gain a better understanding of how landscape pattern influences the spread of EAB at a large scale. Specifically, we wanted to: (1) determine how well landscape metrics predict the presence or absence of EAB, (2) provide a means to model the spatial distribution of future infestations, and (3) use spatial statistics to assess the directional trend of EAB occurrence.
