I couldn't help it in class last week: there was a speaker talking about 'weeds' and she full on said 'weeds destroy soil structure'. I'd been noodling along working on other things, like I have to in class to stay awake, and heard that and just about started foaming at the mouth.
So I politely asked what in the world kind of science makes her say that weeds destroy soils. And that, in reference to the book I've been thinking of dragging into class 'Invasion Biology', it was some pseudoscience that only exists in the heads of native plant fanatics, etc etc.
Aren't weeds the first step in soils repairing themselves?
So on & on. Teacher pulls me aside for a conversation during a break. Something along the lines of 'Kelda I know you're smart, will you just shut up about this because you might confuse the class'. I can be amiable though, and she did come to the agreement that yes, it may be untrue to call some plants 'bad' instead its more correct to say 'that they amend the soil in a way that suits them'etc. But I still should shut up about it.
I bet if I had just a half-hour to describe the conversation in front of the class we all could feel much better, haven't quite asked for that yet....
Anyway, teacher did give me a good challenge.
In reference to using the weeds to work for you she says she's just Never Seen it work out. That all the restoration sites she knows of will be covered again with opportunists if people aren't diligent. And so she wants to make sure that the class learns that diligence is important.
Of course I could name a number of sites where it does work, but these are permaculture places where people live, not public restoration sites. And part of working with restoration is sometimes taking out all the weeds. (The Bullocks still are adamant about pulling
milk thistle, it attempted to devour their lower garden). But that's only one strategy that should be based on observation (they leave many other 'invasives' that don't act that way).
So, to make this a positive, here's the Challenge:
Public restoration site using weeds to enhance it into a healthy ecosystem. As it happens we have the perfect spot for it. The old tacoma driving range has tons of scotch broom, and an excited parks staff that wants to see permaculture gardens...
It will depend a lot on maintenance, and people feeling like they are stewards of the
land. Maybe that's the whole invasives debate in a nutshell. The cities are full of people. If everyone took ownership over a bit of land and learned it well, we could maintain a diverse landscape.
On another note: after class last friday I hosted a free permaculture movie showing in another part of town. I think 1/4 of my native plant classmates were there!
And Sepp (in the movie) has this great little rant about 'bears claw' invasive and how he uses it to make money and
feed his fish. gotta love the guy.
