I can tell you what I would like to see and what a lot of other folks who are in the invasive species councils across the country would like to see, and that is one database for all invasive aquatic and terrestrial species—one that is accessible, in that private citizens and groups who are working on this issue can find data on it and access it and look at it. Also, it would be made such that people can report directly into it, so that citizens can be on the ground and we can make use of an educated citizenry, once we get them educated, being the many eyes out there looking for these things.
As for available examples, there is a variety of systems being used across Canada currently. This use has been undertaken province by province. In Atlantic Canada I'm not aware of any individual database that's being maintained on invasive species. That's why, from my point of view on this side of the country, it would be great to see a national system that everyone would be using.
There are some programs publicly available—one by naturalists, for instance—that are very easy for the public to use. It's actually a maintained system that people could report into and government could put data into and also pull data from for public reporting. It could be a combination of government databases as well as a public reporting system type of database.
