Abstract: The 2002 to 2013 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 2002 to 2013 Detection Likelihood is to inform the 2014 EAB sample design.

Title:
Detection Likelihood 2002 to 2013 Surface for Agrilus planipennis the Emerald Ash Borer (EAB).
Description:
Abstract:
The 2002 to 2013 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 (Downing et al.
2013), in collaboration with Animal and Plant Health Service, Plant Protection and Quarantine (APHIS
PPQ) staff members. The intended use of the 2002 to 2013 Detection Likelihood product is to inform the
2014 EAB sample design.
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 2002
to 2013 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 pseudoabsence 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 2002 to 2013 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 2002 to 2013 Surface
Modeling datasets:
EAB Positives 2002 to 2013– EAB Positives 2002 to 2013– EAB trap catches and visual detection
within the U.S. from 2002 to 2013, referred to as the “EAB presence-only” dataset. The EAB presenceonly dataset contains 8,275 EAB positive point locations within 23 states and 464 counties. 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.
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.
Drainage Index- Drainage Index is based on soil taxonomy and drainage classes from SSURGO and
STATSGO soil data. Soil drainage index is based on soil taxonomy and drainage classes from SSURGO and
STATSGO soil data (Schaetzl et al. 2009).
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.
Position Index- Position index is a terrain index ranging from 0 (flat areas) to 100 (ridge tops). Low
values represent valley bottoms. Position index is generated on a 7x7 kernel and scales the mean
elevation to the surrounding elevation to separate lowlands from uplands.
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).
