I had a property management for 105 acres with dense oaks, poison oak, manzanita and madrone mostly, some junk pine. I wanted a clear fence line on my side of the fence, and the owner did also. For the start I used a brushcutter, weedwhacker to clear out the undergrowth. Just to access it. On large trunked trees I just cleaned them up from trunk base to 7 foot with a chainsaw. Junk trees got dropped. Paint stump killer usually tri on those. After clearing a five foot path, I usually hit it with gly blend then a preemergent. Only other choice would have been to dozer it but owner wanted a narrow path for his ATV and to keep majestic oaks intact. A good plan I think. Ended up being very nice, clear fence line and a real nice inspection path for ATV.
