#25: Arborist
Be very careful about confusing an arborist for a forester, and be even more careful about comparing an arborist to your chainsaw-happy neighbor. Arborists are the people you want to call to check on the health of your trees, but they aren’t even close to being wanna-be lumberjacks.
Arborists have a lot of time to become certified in the diagnosis, treatment, and care of trees and shrubs. A tree would have to be very sick before an arborist would recommend for it to be cut down. They would rather nurse your tree back to health than end its life.
