    Climbing and Pruning Large Coniferous Trees: Lessons Learned in the Pacific Northwest


    Expanding upon the Conifer Care Guidelines discussed at the 2012 ISA Conference in Portland, Oregon, the goals of this presentation are to update and refine the protocol we have developed for managing large evergreen trees in the Pacific Northwest. Canopy-scale pruning, ecological considerations, time-lapse filming of tree work, safety considerations, the Double-System Technique (DST), ground-rescue systems, and storm damage prevention will be covered in this talk.  As many trees in the Pacific Northwest reach their 100th birthday, we hope to help them age gracefully and become urban old-growth.

    Nicholas Whittaker Dankers has been an arborist for 12 years and has worked throughout the Pacific Northwest with a focus on tree preservation. While attending Dartmouth College, Nicholas started Picea Woodland Designs as a tree care company committed to safety, appropriate technology, tree health, and ecological restoration. This experience has been enhanced by working with numerous, like-minded tree services around the Puget Sound in order to develop the highest standards for arboricultural practices. The multitude of large, evergreen trees in the region inspired him to develop the Conifer Care Guidelines and share them with both arborists and the general public. He will be attending the University of Washington's Graduate School of Forestry in 2013.
