Re: GBlist: Dangers of CCA Pressure Treated Wood



We've been considering using some of the  native and naturally rot 
resistant wood species in place of cca treated wood.  My forestry 
connections suggest that walnut, certain species of locust, red cedar, 
and katalpa are all very rot resistent- in some circumstances as much so 
as cca treated wood (my father in law used locust for fence posts on his 
farm, which have been in ground contact for 50 years and still look 
good). In many instances logs can be had for the trouble of removal here 
in Wisconsin. Most of these trees are extremely invasive, and considered 
"weeds" by farmers and woodlot owners. 

Any experiences with these materials? I know it's a hassle cutting and 
sawing and drying.

How about using this ACQ preserve stuff? Anybody tried it?
