Understanding the differences between Canada's handling of the invasive species and the United States position can be difficult. I can recall hearing grumblings from different arborists about the less intensive pest-management plans in Canada. I found an abstract by Kenneth Marchant, about Canada's policies regarding EAB. The abstract says "tree removal at and around infested outliers ... has been discontinued other than for research purposes" (2).
This contrasts strongly with Minnesota's management policy to cut down trees even before the bug is verified in certain areas of St. Paul. They probably mention this because of the advanced state of infestation in Ontario, but I can't imagine it works the same near Sault Ste. Marie.
In relation to communication with the public, Marchant's abstract describes a "slow-the-spread strategy for EAB" as described in a management plan. The strategy involves these two types of quarantines:
- the federal labeling of a county as infested, or
- a legal notice to property owners within a 5-km radius of a positive detection.
It continues, "Both methods of quarantine may be in place in the same area concurrently where it is deemed desirable to slow intra-county spread" (8). I'm not certain just what the owners are required to do (if anything) after given a notice.
