The U.S. Department of Labor's Bureau of Labor Statistics (BLS) refers to arborists as tree trimmers and pruners. These tree care professionals may keep trees healthy by cutting away dead branches. They may work to improve the appearance, value and safety of property by trimming excess limbs and branches from sidewalks, roadways or utility lines. They may diagnose, treat and employ preventative measures against tree diseases. A certified arborist's wages may be affected by the part of the country where he works.
