I think the answer is yes to both parts of those questions. There's always going to be a debate around how much is enough. I mentioned earlier the statistics around the magnitude of trade and travel. On the strategy itself, we've had two recent national fora--one in 2009 and one in 2010--and the strategy has so far stood the test of time in terms of getting that focus on prevention and early detection and rapid response. You still need to manage.
I absolutely agree with your comment about prioritizing species when it comes to the management side. There is definitely management activity to minimize the impact of established species that will always be ongoing. Also, the focus on pathways has stood the test of time, as my colleague from Natural Resources Canada mentioned: under the North American Plant Protection Organization a risk assessment around pathways then means we stop a host of species that might come into Canada through that pathway.
