  •  There are definitely invasives (6+ / 0-)

    that have been welcomed...even invited. One, for example, is the brown trout. Same with the coho and the chinook salmon. All three are intentionally stocked in the Great Lakes by the fishery commission.

    Coho and Chinook were introduced as a way to control alewife populations. Brown Trout was introduced, on purpose, exclusively for eating purposes in the 1800s.

    Some invasives don't compete in the Great Lakes ecosystem...they just occupy a new ecological niche. My understanding of the Brown Trout is that this is the case with them...they live in places where other trout do not. I'm not sure about their effects on newts, but it wouldn't surprise me that there were adverse effects.

    These days, though, there's little use in talking about what SHOULD or SHOULDN'T be in the Great Lakes. The system is wonked up beyond getting back to the "original" balance.  Now it's a question of What Do We Want in the Great Lakes?

    Month by month. (Hope to see you on Twitter)
