Are models being developed to predict the spread of ASR through the U.S.?
Yes. Three models for predicting ASR movement based on weather patterns, environmental conditions, and/or other parameters were developed and tested in 2005. Each have strengths and weaknesses, but performed reasonably well in their first year. Using data collected from sentinel plots, these models continue to be refined. The goal is to link these models together and thereby utilize the strengths of each. At this stage, prediction models are not substitutes for a coordinated monitoring and tracking system.
