Detailed Guide for

Tree Trimmers and Pruners in Alameda County

May also be called: Arborists; and Tree Climbers

What Would I Do?

Tree Trimmers and Pruners cut away damaged, dead, or excess branches from trees or shrubs to clear roads, sidewalks, or utility equipment. They trim trees to limit their size, for visual reasons, or to make fruit and nut harvesting easier. This helps to maintain and improve their appearance, health, and value. Tree Trimmers and Pruners may also cut down and remove entire trees.

Some Tree Trimmers and Pruners specialize in diagnosing and treating diseased and infested trees or shrubs. If the trees or shrubs show no improvement from the treatments, they are usually removed. Tree Trimmers and Pruners may also focus their attention on preventive measures by keeping trees healthy and strong through pruning, fertilization, and proper watering methods.

Tree Trimmers and Pruners may select and plant new trees and shrubs according to the Hardiness Zone Map. This map indicates what types of plants and trees will flourish and grow in a particular area. They may remove or transplant trees or shrubs to other areas that are better suited for their growth. During spring and winter weather conditions, Tree Trimmers and Pruners are busy removing cracked or damaged branches and trees that pose a safety threat.

Tree Trimmers and Pruners perform other duties, such as driving trucks, operating and maintaining equipment, and collecting debris and placing it in piles. They may also talk to the public about tree care and maintenance.

Tree Trimmers and Pruners should be aware of nesting birds. There are federal and state laws that protect native and endangered birds. If they are disturbed during the nesting season citations and fines may be issued. As defined by the California Department of Fish and Game, the nesting season is between February 1 and August 15. Companies involved in large projects that involve trimming and removing trees usually hire a biologist to conduct field surveys of nesting birds in the area prior to starting the job.

Tools and Technology

Tree Trimmers and Pruners use a variety of tools, including aerial lift devices, chain saws, climbing ropes, ladders, lopping and pruning shears, pole tree pruners, safety harnesses, and wood chippers.
