View Full Version : windbreaks

Can anyone recommend some good resources on windbreaks (books or internet are fine, or who in a university or profession would hold that kind of knowledge)?
I'm particularly looking for info on building windbreaks, but also on planting trees etc as windbreaks.

I'm pretty sure Bill Mollison's books get into that. His books also point out that you don't want to STOP the wind, you just want to slow it down. If you put a solid barrier to stop the wind, it will only protect for a certain distance near the ground, then it will slam the area beyond it. See the books, as they have diagrams and plant suggestions.
I'm thinking his Designer's Manual has info on it, in particular.

I think I've had a look in his books before and not found what I wanted but will have another look. Thanks :)

In the book "Introduction to Permaculture" by Bill M. and Reny Mia Slay, it covers the subject over 5 pages and it gives some pretty good ideas, Starts on page 45.
I have a 2000m2 native wind slow next to the same size food forest area, I planted out a mix of natives as some have grown better than others, I think it will be a few years before I notice a real slowing of wind. we get some cracker wind storms here.
One of the main things to avoid is forcing the wind up and over the wind break because once clear of the wind break will fall and tumble into the area your trying to protect, this can be faster than the main wind speed, if you set up the system so wind travels through the trees which slow the wind and does not force it up. Planting small then medium onto large trees will force winds up so try and plant so wind can pass. also be care not to funnel wind down tracks or large gaps as this will increase wind speed too.
I didn't find much on it in the big manual, just one page according to the index.

Thanks baz, I'll have a look in ItP.
I'm looking for in depth resources. My immediate need is to build some wind breaks until I can plant some and they grow. So I'm looking for ideas on that, what works etc.
