Good stuff! If your landowner can get back in there with fire every 3 to 5, he can keep it forever. I've covered a lot of acres with a 5.5 pound arborist top handle hanging off my left hip and a hypo hatchet. I wish I had a nickel just for every gum and hickory I've killed. Southern rainfall and long growing season can change habitat dramatically in one summer.
How well do the hypo hatchets work? Never seen one used, but I have always just imagined they don't offer enough advantages relative to the cost.
