Canopy reduction refers to pruning the foliage (crown or canopy) of the tree to achieve an objective. This is more of a general term for a variety of canopy treatments that can provide aesthetic improvements as well as structural benefits to the crown of the tree. ALL pruning work on ALL trees we work on is performed without climbing spurs. Here are definitions of some of the treatments that fall into this category.
Limb Tip Reduction
This form of pruning occurs at the end of the limbs. Also referred to as end weight reduction. A good solution to reduce risk on failure prone trees or limbs. This is the most healthy way to perform pruning on a tree to firm or enhance weak branches or main structural scaffold limbs. Cuts are small and frequent at the end of the limb. This allows rapid wound closure and decreases the length of the lever arm (limb) and substantially reduces the risk of failure.
This form of pruning occurs at the lower third of the tree. Often a good solution for increased light exposure to gardens, yards or houses. Raising the crown can provide better aesthetics for landscape and allow better air circulation for the canopy above.
This form of pruning occurs throughout the entire canopy. The pruning focuses on removal of deadwood and failure prone limbs. This provides risk reduction of failure prone limbs and/or limbs suspended in the canopy. It also has an aesthetic benefit: clean lines throughout the tree allow the trees look much more attractive without the redundancy of deadwood. The image below shows two climbers working the exterior of the crown to manage the form of the tree for structural viability.

This form of pruning typically occurs on multiple portions of the canopy. The pruning treatment goals focus on improving the view while maintaining the health of the trees. Often this can be accomplished by both highlighting the trees and the view, through the practices mentioned above the trees end up looking better, being less hazardous. In this way both objectives are met.
Risk Assessment & Consultation
Risk assessment provides a standard for arborists to evaluate trees and inform their clients with substantiated advise about the risks their trees present to their property. The risk assessment qualification is based on a standard methodology learned in a 2 day course and tested with a 1/2 day exam. The course is both classroom time and field work. It provides arborists with the tools they need to evaluate a tree based on visual clues and other data that can be derived from testing. This is another way we can help provide you with the best information possible to make informed decisions to retain healthy trees and the safety of your property.
Part of living around trees is living with their inherent risk. Often this risk can be mitigated using proper tree care techniques. However the forces of nature are unpredictable. When tree failure does happen it can often be catastrophic. However problematic or drastic the damage is, we have the appropriate rigging and equipment to safely and efficiently get the problem solved and the site cleaned up.
Technical Tree Removal
Often our job takes us into back yards, over houses, near infrastructure or around prized landscapes. Trees that grow in close proximity to these features arent always small or trivial to remove. When this is the case they require intricate rigging to manage the wood and branches as the tree is sectioned down. Our staff has formal training on how to safely and effectively get this job done. We are equipped to manage the removal process as well as the cleanup to leave your site looking tidy and clean.

There are times when trees have been pruned mechanically or naturally in an improper way. Environmental failure, topping or other improper techniques can have dramatically detrimental, long-term effects on a tree. Working with trees that are in this condition is one of our specialties. The restoration process can occur on a small fruit tree or a massive broad leaf or evergreen. We employ multiple different techniques to develop a treatment tailored for the specific needs of the tree in question. To ensure the tree remains healthy these treatments usually require multiple pruning sessions to accomplish the goal.
Occasionally we are able to save trees and retain their safety by using cables to support them. Often when a defect in the canopy exists we can utilize the remaining structure of the tree to reduce the risk of failure. By knitting the tree together with a cable, the weak unions or attachment points (defects) can be supported by using the other parts of the tree. There are two kinds of cables that we employ. Static and Dynamic cables both have their purposes and applications.
This photo was taken at about 90' aloft in a Grand Fir. The tree was a very valuable specimen to our client but unfortunately it had many defects within the canopy. After inspection we determined it would be best to put static cables in the tree. Cabling the multiple tops together allows them to move as one and dramatically reduces the risk of failure.
Transplanting large trees is exceedingly difficult. A proper understanding of tree biology and how they grow is imperative for survival. This process also takes heavy equipment and careful installation to get it right. We offer this service as well. We have an excavator to aid in both the site prep and the transplanting process. We can also help with species selection and can source the trees for you. Having your trees planted by an ISA Certified Arborist on the Olympic Peninsula is something only we can offer.
