August 2020: TCIA Magazine "In our roles as business leaders, supervisors, gear inspectors and safety trainers, we see tons of climbing gear. An alarming portion of that gear is unmaintained, poorly configured or beyond its reasonable service life. Those observations led us to ask, who is responsible for the condition of a climber’s life-safety equipment? Is it the climber or the company? Who is responsible when climbing gear fails? With a combined 23 years in this profession

Tree133 has worked on this beautiful Japanese laceleaf maple (Acer palmatum) for the past few years. In fall of 2019, we removed dead/decaying foliage and interior deadwood as well as a few damaged interior limbs (abraded by other branches). That first phase greatly improved the tree’s appearance and we noticed better foliage conditions the following spring. This January, we performed light raising and thinning to improve light/airflow throughout the canopy and expose a bit

Have you ever seen a tree that looks like it's propped up on legs? The tree likely grew on debris or sprouted on a nurse log, rather than rooting directly in the ground. This Western hemlock (Tsuga heterophylla)  in the Lake City neighborhood in North Seattle had died and was going to be removed. It was possible to excavate around the roots and actually see the structure and nurse log. For 40-50 years, the nurse log provided ground cover and reduced soil erosion around the r

Leyland cypress  (Cupressus x leylandii) is a hybrid species resulting from a cross between the Alaskan cedar (Chamaecyparis nootkantensis) and the Monterey cypress (Cupressocyparis macrocarpa) .   It is a popular choice for privacy screening because of its extremely fast growth rate - quickly growing 40-60 feet high and over 15 feet wide. In prime growing conditions, they can reach 100 feet tall and 50 feet wide. In the Pacific Northwest, Leyland cypress is often an inexpens

Birds, insects and small mammals all use trees for nests, nurseries, storage areas, foraging, roosting, and perching. If a tree needs to be removed, rather than cutting it to the ground, it may be possible to retain valuable habitat with a wildlife habitat snag. In this video, Karsten  explains how arborists help preserve urban wildlife habitat, imitate wood breaks that happen naturally and create bird boxes to provide nesting cavities. Want to learn more about snag trees? Li
