native range - yellow
non-native area - red/brown
Does this actually mean invasive? No.. Means introduced there. Some feel that is however invasive.
Not dogging ewest, just using that key as an example. Everybody does it different but Kansas's process is "If the species has been verified in an impoundment, or verified in a down-stream area from where a stocking is requested, in the last 70 years and is not on the invasive list" they can be stocked without the paperwork process that usually accompanies this type of stuff.
Thinking out-loud here but for a species that doesn't seem to do super well where LMB exist and prosper it's kind of funny.
