Chapter 18 - Energy, Transport, and Growth in Plants

There's more to trimming trees than simply sawing away. Proper trimming requires both hard work and some careful thought. Trimming can also protect both the health of a tree and the plants around it. If you'd like more information, consider contacting a local arborist or tree worker. The following sites can teach you a bit about what arborists do and help you to locate one in your area:
Arboriculture Online: This is the home page of the International Society of Arboriculture. It includes Tree Care Consumer Information and a Certified Arborist List, which you can search to locate a certified arborist who works in your area.
National Arborist Association: This is the trade-association for companies that care for trees. The site has information on what arboriculture is and how to become an arborist.
To learn about how and why electric companies trim trees, visit Trimming Trees for Outage Prevention and Safety by the Lincoln Electric System in Lincoln, Nebraska.
