I'm assuming by 20' circle you mean 20' diameter. And I'm assuming only one layer of timbers. 3.14 x 20 = 63 feet of timbers needed / 8 foot long timbers = 8 timbers, for a 20' radius circle, double the number of timbers, and for each row of timbers increase the number of timbers accordingly. The closer to circular you want you'll need to cut the timbers shorter. 8 timbers will make an octagon (like a stop sign)
nothing :D
Native timbers are simply timbers that are found locally. Native timber can also be 'second growth' timber, which means that it is sustainable.
