Last point on this and I'll settle down a bit.
Just a thought experiment. What happens in 50 years when/if brook trout are federally listed? Pa would then list them at the state level. If you curry favor to a species that has been scientifically proven to be injurious to a species that is now listed, there's no way to unscramble that egg.
I know a lot of people like wild brown trout. The question is, if you protect them, how does that work out down the road if the native species gets listed for federal/state protections? See AZ, CO etc. for what they're dealing with now with cutthroat. Just because we have a somewhat robust population of brook trout today doesn't mean that it will be that way forever. Especially if we increase the number of nonnative fish competing with them.
