The paper identifies high-risk areas for invasive species spread by analyzing transport infrastructure and correcting sampling bias using historical data on Lycorma delicatula.

The paper evaluates three pest survey methods for spotted lanternflies, finding seasonal and abundance-dependent detection probabilities, with traps performing better on larger trees and preferred hostplants.

This paper optimizes invasive species spread rate estimates by considering spatial scale and temporal variation, finding that coarser scales and logistic models better capture invasion dynamics.
