Emerald Ash Borer in Pacific Northwest

The Emerald ash borer is one of the most destructive invasive pests in central and eastern United States, it has killed ten millions ash trees in > 30 states and severely altered ecosystems that depending on these ash trees. EAB was found in Oregon State in 2022, marking its first detection in the Pacific. Its Oregon establishment is of great concern, as it could devastate ash swales and sensitive riparian zones, the loss of these trees could further endanger wildlife that depend on forested wetlands. In response to its establishment, Oregon Department of Agriculture (ODA) has adopted a quarantine area to slow the spread of EAB by restricting the movement of host tree materials to unaffected locations in the state, the alive monitoring of EAB spread can be found here. The complete guide to EAB can be found here.

Potential distributions in the Pacific Northwest

Here is the potential distributions of emerald ash borer in the Pacific, which were developed based on physiological and 5 correlative niche models. The correlative niche models were generated by Maxent distributional models, that used the pooled native and introduced occurrence records, together with the annual trends and extremes of temperature and precipitation, and prevalence of deciduous trees as predictors. Model was produced following the best practice. An interactive website was also developed to display the habitat suitability:
