FAQ - Answer
A very effective mean of removing poison oak is with the use of grazing animals. Herbivory, or grazing, not only removes the above ground portions of the plant but over time, the roots will become starved of their carbohydrate stores and the plants eventually collapse. Sheep would also work but would require fencing, whereas goats could be tethered and moved around the property to target the plants. Another approach would be to severe the plants near the ground and spray the emerging sprouts with glysophate (Roundup®) when the shoots are very small. As long as the chemical does not come in contact with the oak leaves, there should not be any negative impacts.
