Hey, I'm working on a bid for clearing buckthorn on a site for a guy who is building soon. He is very concerned about any kind of root damage to the nice white pines on the property. The site has the thickest buckthorn I've ever seen, the majority of it is all about 1" diameter. I want to rent a fecon but he is concerned about compaction. What is everyone's experience with this? I was thinking keep a drip line buffer to do by hand, is that enough to not have any concerns for compaction? Is there any publications you can link me to to read up on? Thanks!
