We're not gung-ho about invasive species, but somehow poisoning an entire lake to get rid of them seems counterintuitive. Nonetheless, California's Lake Davis will get that treatment from state Fish and Game Department officials tomorrow, in the latest attempt in 15 years to rid the reservoir of nonnative northern pike.

Some idiots illegally introduced northern pike into Lake Davis -- they're voracious predators and the danger is they'll escape and eventually arrive in the California Delta. Once there, they'll pretty much decimate the already-declining salmon runs (both coming and going), knock the steelhead for a loop, etc.
This isn't something done lightly, but it's hell of a lot better than watching what's left of our Sacramento River salmon runs disappear down the throat of a fish that doesn't belong within a thousand miles of here.
Any fool knows that.

Add you 2 cents if you like.

In this case, yes, the plan to poison Lake Davis is wholly unpleasant, but everything else has been tried (what's your plan).
The environmental consequences of Northern Pike in the California Delta are truly horrifying, especially in terms of our already beleaguered salmon populations -- the returns for which this year have plummeted.

Poisoning whole ecosystems to root out those that are already established is questionable.
Elsewhere it's likely that herbicides will be used around a large swath of the west's public lands in the coming year to kill off some of the weeds there, and this summer the state of NJ sprayed its northern forests with BT to kill the larvae of gypsy moths, but managed to kill lots of other moth and butterfly caterpillars. Hopefully no Luna moths were killed, but it's likely.
So, mixed results. I'll take Luna moths and a few gyspy moths thrown in, too, thanks.

I keep hearing "poison bad."
Yes it is. But given that fish & game has tried explosives, netting, electroshock and overharvest, I've gotta ask: What's your solution?

A grassroots group in the region, South Yuba River Citizens League, has the dirt:

Sounds like a cluster-you-know-what all 'round.
