Abstract: The 2012 Detection Likelihood model for the Emerald Ash Borer (EAB), Agrilus planipennis, was
produced for the Contiguous 48 United States (CONUS) at a 1 square kilometer (1 km2) resolution by the U.S.
Forest Service, Forest Health Protection, Forest Health Technology Enterprise Team (FHTET), in collaboration with
Animal and Plant Health Service, Plant Protection and Quarantine (APHIS PPQ) staff members. The intended use
of the 2012 Detection Likelihood is to inform the 2013 EAB sample design.

Title:
Detection Likelihood 2012 Surface for Agrilus planipennis the Emerald Ash Borer (EAB).
Description:
Abstract:
The 2012 Detection Likelihood model for the Emerald Ash Borer (EAB), Agrilus planipennis, was produced
for the Contiguous 48 United States (CONUS) at a 1 square kilometer (1 km2) resolution by the U.S. Forest
Service, Forest Health Protection, Forest Health Technology Enterprise Team (FHTET), in collaboration
with Animal and Plant Health Service, Plant Protection and Quarantine (APHIS PPQ) staff members. The
intended use of the 2012 Detection Likelihood is to inform the 2013 EAB sample design. Pest information
for EAB was taken from the Exotic Forest Pest (ExFor) website (http://foresthealth.fs.usda.gov/exfor).
The likelihood of detecting EAB was modeled using the Maximum Entropy (MaxEnt) interpolation
technique. MaxEnt identifies significant associations between presence and absence trap data from 2012
with selected site variables and then maps the probability of EAB presence in a geographic context. This
non-parametric approach has been demonstrated to have utility for generating species distributions,
because of its treatment of locations where a species has not been observed as pseudo-absence locations.
Pseudo-absence is defined as a species being absent from an area for one of three reasons: 1) the habitat
cannot support the species, 2) the species has not completely filled its geographic niche, or 3) the species
is present but was not detected. For a species such as EAB that is still emerging and expanding into its full
geographic range this is an appropriate modeling approach.
Presence and absence EAB data from 2012 was provided by APHIS PPQ and state cooperators.
Independent variables were investigated and selected to represent where EAB is likely to establish (Table
1). A bias raster, based on the autocorrelation of positive EAB locations, was used to correct for sampling
biases. The MaxEnt bootstrap option was used to generate 100 iterations to develop an average Detection
Likelihood model. For display purposes and ease of interpretation the data were partitioned into four
classes (Table 2).
Purpose:
The product's intended use is to predict where A. planipennis is most likely to be detected in the U.S and
to aid in the development of a detection and management strategy for A. planipennis.
Emerald Ash Borer Detection Likelihood 2012 Surface
Modeling datasets:
EAB Positives 2002 to 2012– EAB trap catches and visual detection within the U.S. from 2002 to 2012,
referred to as the “EAB presence-only” dataset. Acquired and compiled from APHIS PPQ and state
cooperators.
Input Variables:
Elevation- Digital Elevation Model (DEM 30m) from National Elevation Dataset (NED) resampled
(bilinear interpolation) to 1km resolution and converted from meters to feet.
Distance to Rest Area- Euclidean distance from Rest Areas (POI Factory 2012 http://www.poifactory.com/node/14656). Rest area point locations were identified as potential introduction locations.
Distance to Rest Area- Euclidean distance from Rest Areas (POI Factory 2012 http://www.poifactory.com/node/14656). Rest Area point locations were identified as potential introduction locations.
Traffic Volume- Traffic Volume point locations, from across the U.S., were compiled from TrafficMetrix
and used to interpolate a Traffic Volume raster using simple variable distance kriging.
Road Density-Developed from rasterized 2003 Tele Atlas Dynamp Transportation v. 5.2 layer for each
state at 100m. Density was calculated by summing the number of 100m road pixels within a 1 km pixel.
Housing Density- Housing density data developed by Theobald (2005) using the 2000 U.S. census data.
Moisture Surplus/ Deficit- 1, 3, 5 Year moisture surplus and deficit for 2010 from PRISM climate data
(Koch 2011).
Distance to Campground- Euclidean distance from campgrounds identified by federal and state
cooperators. Campgrounds were identified as potential introduction locations.
Urban Areas- Urban areas within the ash range identified as having a population greater than 100
persons per square mile from the 2000 census (Withrow 2010).
