Philip Kelley and Jamilee Kempton, August's workshop instructors

We hear you! When members share their education requests in our annual member survey and workshop evaluations, PNW-ISA identifies how we can meet your needs. Members repeatedly ask that the Chapter offer more tree climbing workshops and we responded!

This summer PNW-ISA is hosting four tree climbing workshops. The first two were in early June, the Women’s Tree Climbing Workshop (WTCW) and the Advanced Tree Climbing workshop. Both workshops were taught by an all-female instructional team. These workshops brought members from across the Chapter. Both the U.S. and Canada were represented. A huge thank you to the WTCW committee for acquiring sponsorships, reviewing scholarships, and coordinating details and logistics for these workshops!

In August 2019 PNW-ISA will offer two climbing workshops at the Washington Park Arboretum in Seattle, WA. Read More "Check Out Our Tree Climbing Workshops This Summer!"

To PPE or Not to PPE

Learn more about Ryan Senechal.

Although hardhats and hearing protection are, for the most part, in use by tree workers across the PNW, insidious attitudes are always lurking towards PPE whether it is aimed at premium protective equipment, PPE options not required by regulators (gloves, protective footwear or chainsaw pants in some parts of the chapter), PPE care, or the ongoing inspection and replacement of PPE. I expect that most tree care operations and their employees consider themselves to be compliant on the PPE front (particularly those that read this newsletter). If you feel that to be the case with your workplace, I have one question to ask:

Does your workplace request third-party observations and recommendations (formal or informal) on interventions that might improve the outcomes of worker health and safety, worker ergonomics and worker efficiency via PPE?

Hopefully the answer is yes.

It’s probably time to start talking about PPE as a program or system rather than a thick piece of plastic intended to keep skin from disappearing or bones from shattering. Read More "To PPE or Not to PPE"

Root Removal Best Practices

Richard Gessner
Monarch Consulting Arborists LLC
Learn more about Richard Gessner.

To keep up with research based changes in arboriculture and urban forestry we rely on guidance from a number of professional sources. The most important are the American National Standards Institute (ANSI) Practices and Limitations.  Because the ANSI A300 standards are written in a very austere style, they are interpreted and expanded upon in the ISA Best Management Practices (BMP’s). Both of these types of publications guide professionals in writing and implementing tree work.

After the Storm: A Symposium Co-Hosted by PNW-ISA and UW Botanic Gardens

The doom and gloom of storm work may drift away as quick as the seasons end. Our industry's stories and experiences get lost in the evening weather report about felling trees and chipping debris. These times of weather events are some of the most difficult and dangerous work in our field.

The symposium features six case studies presented by a variety of tree professionals. These studies will cover best practices and lessons learned about storm preparation, management, and post-storm prioritization. Presenters will include Municipal, Commercial, Consulting, and Utility arborists, as well as allied professionals.

Online Location

This symposium is available for remote attendance online through the University of Washington. Gather a group at work and watch together. Each person taking the online workshop will need to register to receive CEUs.
