I have been cutting a bunch of ash that the city cut down due to emerald ash borer infestation. They have cut down alot of trees over the winter and it makes great firewood after seasoning. I have cut probably three full cords so far for next season, but would like to get a couple more. The trees that are left have a thick (probably an 1" to an 1 1/2" diameter vine growing up them. My first thought was poison ivy, so I have avoided these trees so far. I know what grape vines look like and these are not grape vines. They have a hairy root structure running along them into the ash bark. I could identify them as being poison ivy if there were leaves present, but there are none. Any ideas as to how to remove this stuff and still use the wood? I am very allergic to poison ivy and don't wan't to get it.
