That was the example I would have quoted. As you noted, the degree of invasiveness, or the degree of damage that a particular species can cause, varies. Asian longhorned beetle is a more observable beetle that causes large-scale damage, very large holes, in the trees it attacks.
The Canadian Food Inspection Agency and the Canadian Forest Service of Natural Resources Canada, as my colleague said, were able to detect that invasion and establishment early, as opposed to the emerald ash borer, which was mentioned earlier by one of the members of the committee, that is extremely cryptic. By the time you can see symptoms within an affected tree—really, the population of trees in that area—it is past being able to respond in a positive way.
So invasiveness, damage, is very much species-specific. Asian longhorned beetle is one of the few very good success stories. It's still under quarantine, but it is considered controlled in Canada. At this time there are other outbreaks in the United States, particularly in Massachusetts, that bear watching as well.
