[permaculture] Fodder trees or invasive weeds?

I don't know much about tagasaste (except that I thought Ashland is too cold for it), but I've never heard of autumn olive being a weed. It's cousin, Russian olive, is a dryland species that has become invasive east of the Cascades, but I don't know of any other Elaeagnus with this trait. As far as Pawlonia goes, I'd be very surprised if it was able to reproduce with our dry Summers, except possibly along waterways. And if you want to know about black locusts fixing nitrogen, just look at their roots: mine are covered in nodules.

A couple of years ago I got some tagasaste and autumn olive seeds,
which I'm just now getting around to germinating. However, I am
a little worried about introducing invasive species. I've also got
a couple of pawlonias, which some accuse also of invasiveness.
I know the invasive potential depends on local climate, and of course
our goats will be happy to do their best to prevent spread. And
I doubt tagasaste will survive our wet clay, in any case. But I'd hate
to be the one to introduce the local equivalent of kudzu, which I've
heard also makes great goat fodder...
We also have honey locust; what's the last work, is it nitrogen fixing
or not? I find mixed information on the web.
