It is just a string of 7 trees around my pond that hide it and our house from the front 9. I would love to have goats but not really a feasible option for me.If those are 70' tall, you might be able to interest a logger in doing a thinning for you. Five acres is a fairly small tract so look for a smaller outfit that you can trust to not screw up the trees you want left. If it's just the ivy you want gone, goats or Roundup or one of the forestry herbicides will work. You need a good sticker on poison ivy, the leaves are tough to wet.
