    Description

    Landscape metrics, including host abundance and population density, were calculated using forest inventory and land cover data to assess the relationship between landscape pattern and the presence or absence of the emerald ash borer (EAB) (Agrilus planipennis Fairmaire). The Random Forests classification algorithm in the R statistical environment was used to create a model relating the relative importance of landscape predictor variables to the presence/absence of EAB detected from 2003 to 2009.
