Redwood Tree Removal Case Study. Pro Climb was recently contracted by Pro Climb to carry out the removal of 9 mature Redwood trees located at YMCA Camp Adair, Hunua.
Redwood Tree Removal Project Summary
The Redwood trees in question have had a history of limb failure and breakages of the main central stem due to storms. As such, they resulted by growing multi-stemmed leaders which have formed compression forks. The recent storm in late January of this year brought a number of branches down onto the bunk houses situated beneath the trees.
Due to the height of the trees the bunk houses, central meeting area, and driveway all form target areas for any limb loss or tree failure. Given the location, form, and species of the trees, and the existence of a high target area beneath them, it was felt the safest option was to remove them and replace with suitable alternative species.
How we approached the Redwood Tree Removal
Due to the close proximity of the trees to the structures surrounding them a variety of arboricultural techniques were utilised for their removal. Adjacent trees (which were to be retained) bordering the driveway meant that none of the Redwoods could be felled whole without a significant risk of damage to surrounding targets. There was some open space available in the form of a wide access driveway and this was used to remove the Redwood trees bordering it by a conventional cut and drop method.
When it came to removing the top sections of these trees a directional pull line was used to ensure accurate placement of the piece being removed. Once at a suitable height these trees were felled from the ground, again using a directional pull line for accuracy.
Rigging Systems Ensured Safe Redwood Tree Removal
Due to the confined space offered by the trees adjacent to the bunk house a conventional cut and drop method was not appropriate. Instead rigging systems were installed in the trees to safely lower the sections being removed to the ground. The Pro Climb easy rig with a 14mm rigging line passing through an ISC rigging block was used to lower the smaller sections.
When it came to the larger sections the system was upgraded using a 16mm rigging line and a GRCS lowering device. The GRCS also allowed us to pre-tension the rigging line prior to removing the section, and to easily manoeuvre the sections once they had been removed.
Again, once these trees were at a suitable height they were felled using a directional pull line attached to a tractor. A redirect was installed at the base of a nearby Oak tree so that the tractor could be out of the direct line of the falling trees.
Redwood Tree Removal Debris will heat Bunk Houses for many years
All the debris from the tree removals was to remain onsite for processing by the owners. The wood is to be used to heat the bunk houses for several years to come. By keeping the debris on-site we were able to significantly reduce the amount of fuel needed to process the waste and reduce the cost for the customer.
Overall the job went very smoothly and was completed within the estimated time frame. The pre-existing hazard was removed and the site is ready for more suitable species of trees to be replanted ensuring the continuing canopy cover of the site.
