Interesting note on the northern crayfish, Orconectes virilis, in Alberta. I spoke with the lady in charge of the invasive species monitoring program last year and because these crayfish are known to be in the Beaver river system in Alberta they are considered a native species and not on the Alberta invasive species list. The Rusty crayfish, if it makes it here will be an invasive species.

Here's a good web page with crayfish info. It just isn't complete on the range. Map doesn't show them too far into Alberta but the crayfish are.
