A knowledgeable and experienced arborist knows that all tree pruning is not equal. The arborist assesses each tree individually and then decides what type of pruning the tree is in need of. Crown cleaning, crown thinning, crown raising, crown restoration, deadwood pruning and training pruning are nationally accepted standards of tree pruning developed by the American National Standards Institute (ANSI). The standards are extensive and involved. They are there to protect the consumer.

Trees and the Environment
- Trees renew our air supply by absorbing carbon dioxide and producing oxygen.
- The amount of oxygen produced by an acre of trees per year equals the amount consumed by 18 people annually. One tree produces nearly 260 pounds of oxygen each year.
- One acre of trees removes up to 2.6 tons of carbon dioxide each year.
- Shade trees can make buildings up to 20 degrees cooler in the summer.
- Trees lower air temperature by evaporating water in their leaves.
- Tree roots stabilize soil and prevent erosion.
- Trees improve water quality by slowing and filtering rain water, as well as protecting aquifers and watersheds.
- The cottonwood tree seed is the seed that stays in flight the longest. The tiny seed is surrounded by ultra-light, white fluff hairs that can carry it on the air for several days.
