Trencher for Oak Wilt Suppression
Some very interesting reading yellowdog.
I'm currently in the urban forestry program at NDSU up here in Fargo, ND so I think I'll have to see what my professors have to say about this.
I know right now the big thing for us up here is the Emerald Ash Borer. Right now it's about 250 miles away but I'm sure it'll be here soon. Lots of large boulevard trees might have to go. Pretty sad!
