Featured Tree
Bremerton Naval Base Giant Sequoia
Sequoiadendron gigantium
Height: 120 feet
DBH (diameter at breast height): 10 feet

In July we collaborated with Scott Baker of Tree Solutions Inc., a well-respected Seattle tree consulting firm, to improve the condition of a massive Giant Sequoia. It had suffered a large limb failure during a wind storm and required immediate attention. We were called in to relieve some of the cantilever weight on the other large limbs and remove the hazardous deadwood that hung above a well traveled walkway. Conor and Scott set a number of cables to reduce the threat of further limb failure. The failed limb itself was 31” in diameter. We brought the broken limb back to the base of the tree, rigging it down to the ground with a block and tag-line. Using non-invasive techniques we were able to enhance the structural integrity of the tree and preserve its aesthetic character.
Rainforest Old-Growth Climb

In August Conor and Mick made their first recreational old-growth tree ascent on Rugged Ridge. Contouring the Olympic National Park boundary before dropping into the Bogachiel watershed, the Rugged Ridge trail provides access to some of the finest big trees on the peninsula. To the best of our knowledge we claimed the first ascent on a tree we've come to call Big Iron. At approximately 160 ft. this tree stands high on the ridge overlooking acres of old-growth. We footlocked 100 ft. to the first limb then switched to double rope technique to complete the ascent. On the way up we found a couple of huckleberry plants thriving high in the canopy and ultimately a beautiful panoramic view of the nearby ridges and valleys.

ISA Conference

Conor had the opportunity to attend the international ISA conference this year in Portland Oregon. The conference was both informative and inspiring. Researchers from around the world covered topics including tree health, risk assessment, and work site safety. A visit to the trade show rounded out the trip. Companies displayed software solutions, tree injection treatments, climbing supplies and heavy equipment. Furthermore, climbing techniques and field safety techniques were discussed within the trade show. Nicholas Dankers a good friend and respected arborist in the Seattle community gave a presentation on climbing safety. He demonstrated his techniques on a real tree inside the convention center.

Sitkum Newsletter September 2012
Dear friends,

As fall approaches and leaves begin to turn we have another season's updates to share with you. Summer found us climbing bigger trees and solving more difficult challenges than ever. Collaborations with experienced colleagues and attendance at this summer's International ISA Conference have helped us continue to build our skill sets and advance our knowledge of trees. With increasingly turbulent weather around the bend we'd like to apply these skills to help you prepare your trees for the coming months. We are committed to making your trees an asset to you and your property.

Thank you for your continued interest and support,

The Sitkum team
Seasonal Treatment Recommendation: Winter Storm Preparation


Tad sets steel cables in a Grand Fir with multiple tops to improve stability

Now is the time to begin looking at the hazards your trees may pose during winter storm events. Potential risks range from limb tear-outs to full on tree failure and can jeopardize personal safety and property. We can assess your trees for risk of failure and develop solutions that will benefit your safety and their health.

We offer a variety of treatments to prepare trees to weather wind and snow storms. Reductions and cabling can drastically enhance the structural integrity of a hazardous tree. Limb tip reduction can reduce the stress trees undergo under the weight of snow and ice. We have the knowledge, capability and experience to improve the safety of your trees and leave them in a healthy and aesthetically pleasing condition.


Featured Project: Whidby Island Crane Removal


Conor discusses the work plan with the crane operator

This summer we completed a large crane assisted removal on Whidby Island. The tree, a Douglas Fir, was about ten inches from the client's home and had two co-dominant stems—one of which showed significant die-back due to root damage that occured during excavation for a remodel. Working with cranes not only allows for speedy and safe removal but it also enables the climber, in most scenarios, to cut bigger sections in tight residential areas. These sections can be tailored for milling and other applications. In this case our client asked that we remove the main crotch and stem of the tree in sections that would allow him to mill slabs and lumber for future projects.

In preparation for the removal Conor climbed each of the stems and removed the limbs. Most of them were zipped down on a speed-line to clear fences and structures below the tree. After the tree was prepped and the crane had arrived Conor was lifted on the hook with slings to set the first pick point. He was able to complete the removal in three cuts. The crane operator left the sections in a neat stack ready to be prosessed into building materials. Visit our website www.sitkumtree.com to see videos of the removal.
