Tree trimmers and pruners, also called arbolists, cut off dead or leftover branches of trees or shrubs to clear utility lines, roads, and sidewalks. Many of these workers strive to improve the appearance and health of trees and plants, and some specialize in the diagnosis and treatment of tree diseases. A tree pruner, also known as an arborist, manages the health, maintenance and appearance of trees by pruning diseased or damaged branches. Tree clippers work in a variety of places, such as residences, schools, hospitals, hotels, and mall indoor gardens.
Utility companies often hire tree trimmers to clean trees that are near power lines and remove any debris in the area. Some companies hire tree trimmers as part of annual landscaping maintenance of a site. The functions include the use of hand and power tools along with scaffolding equipment and the operation of heavy machinery such as boom trucks. A tree cutter is just another way to describe an arborist.
The arborists have studied arboriculture and are licensed to prune and remove trees in each state and city where they carry the correct credentials. An arborist (or tree surgeon or tree pruner and pruner, as they may sometimes be called) is an arboriculture practitioner. These are professional professionals who can grow, manage, care and rehabilitate trees and shrubs. There are also foresters who are professionals who specialize in managing an entire forest and can be responsible for harvesting timber, while an arborist specializes in individual trees.
A coarse pruning may not have adverse effects on a large, healthy tree, but a tree that is under pre-existing stress or that has a potential for health problems can suffer irreparable damage if too much canopy is removed. It's a common misconception that tree trimmers and certified arborists are the same, but when it comes to planting, pruning, and caring for your trees, not all tree care services are created equal. There are many respectable and experienced tree surgeons, but there are also many without the necessary knowledge to protect and save a tree. The first pruning after buying trees and shrubs involves removing broken, crossed and pest-infested branches.
Tree trimmers without an ISA certification may not know the proper depth to plant trees of different species, or they may overprune, which can damage and even kill otherwise healthy trees. They are best suited for removing trees and chopping firewood, but can also be used to prune living plant material. Most arborists, 95% or more, run suburban tree service companies that prune and cut down trees in residents' yards. The protagonist of Italo Calvino's novel The Baron of Trees lives life on the ground as a child and spends the rest of his life swinging from tree to tree in the Italian countryside.
Arbolists are also sometimes called tree surgeons, since they not only have to remove dead branches and prune a tree when necessary, but also monitor the health of the trees under their care and recommend treatment. Certified arborists are trained to assess existing trees on the job site and work with developers, civil engineers and landscape architects to create a tree protection plan. In addition to the ISA, the Tree Care Industry Association (TCIA) oversees tree service providers in the United States. They do not just look at part of the tree to cut it, but they diagnose the entire body of the tree so that the correct solution is made.
While both usually offer tree pruning services, as well as planting and removal services, only arborists are truly trained and educated to protect tree health and care and plant trees properly. In France, a qualified arborist must have an Ornamental Tree Management certificate, and a qualified arborist must have a Tree Pruning and Care certificate; both delivered by the French Ministry of Agriculture. .
