Due to the COVID-19 pandemic, we have experienced numerous federal, state, and local health or business closures affecting our members. While the jurisdictions, business activities affected, and length of time for the closure may differ, most will exempt essential businesses or essential business activities that directly relate to public safety.

(Tigard, OR, Monday, March 16, 2020) PNW-ISA is postponing its March and April education programs to limit in-person contact. We are taking every precaution necessary to ensure our members remain healthy and safe. We have been in communication with instructors and facilities to determine rescheduling dates and will announce these dates as soon as they are finalized. When rescheduling, registrants will be notified and automatically moved into the new dates selected. If you are unable to attend the new date, you will be able to cancel your registration at that time and receive a refund.

To reduce exposure to COVID-19, PNW-ISA will be hosting conference calls/virtual meetings for its board and committees. We are doing everything possible to reduce exposure and adhering to recommendations for social distancing and isolation.

PNW-ISA will continue to monitor May activities such as our educational workshops and tree climbing competitions as we don’t want to put anyone at risk. We will continue to make informed decisions over the next few weeks and update members and registrants immediately.

We hope you and your loved ones remain healthy and safe as we navigate this time together.

How Do We Galvanize Local Climate Action?

Collaborative for Advanced Landscape Planning, University of British Columbia 

Uncertainty, denial, pessimism. These are the words commonly associated with climate change today, especially as news headlines reveal devastating stories about wildfires, heat stress, and other climate-related disasters across the world.

How can we turn the conversation around, to include messages of hope for the future instead? How can we bring climate change and its solutions down to the local level where people care the most? How can we encourage friends & neighbors to take collective action against one of humanity’s most pressing problems? Read More "How Do We Galvanize Local Climate Action?"

How Do Urban Tree Managers in the Pacific Northwest Decide What Trees to Select?

Dr. Paul Ries, Oregon State University, Corvallis, OR & Joshua Petter, Tree Solutions Inc, Seattle, WA

Tree selection decisions at the municipal level are made by many different natural resource professionals, including arborists, urban foresters, planners, and landscape architects. A recent study by Oregon State University aimed to explore how managers make tradeoffs and prioritize different tree selection criteria to better understand how trees are selected for public lands. We surveyed primary contacts for Tree City USA designated cities across Oregon and Washington. Of these municipalities, 79 out of 151 responded (52.3% response rate), with six municipalities providing responses from more than one department for a total of 85 responses.   Read More "How Do Urban Tree Managers in the Pacific Northwest Decide What Trees to Select?"

Greetings fellow arborists, I wanted to take a moment and update everyone on a few TREE Fund things.


The 2019 PNW ISA’s Annual Training Conference’s Fundraising for the Tree Fund was an absolute success. Between the Silent Auction, Heads or Tails game, and 50-50 Raffle we netted $10,895.73 to donate to the TREE Fund. That’s excellent! A massive thank you goes out to all the donors for the auction and games, as well as to all those of you who participated. Read More "Fundraising, Webinars, and Scholarships"

If you are an arborist that is operating a tree services company in Oregon, are you aware of how many licenses you must maintain to plant and remove trees? No, this isn’t a riddle, it’s a serious question that could prevent your company from receiving hefty fines and possible civil penalties.

ISA Compliance Program Series Volume 1: ISA Code of Ethics

by Rosa Gutierrez, Compliance Services Manager at ISA

ISA is responsible for maintaining and supporting the integrity of our credentials, and we accomplish this goal in many ways. One resource we utilize is our internal compliance program which has four main areas of focus: facilitating compliance with ANSI/ISO standards, management of the ISA Code of Ethics charges and subsequent cases, management of any “appeals” of those outcomes and the protection of the logos used to identify individuals holding credentials.
