I normally use this space to highlight our industry standards. My last update centered on getting our Regional Plant Appraisal Committee formed and working. The COVID-19 outbreak has caused a delay in this, and is affecting us all personally and professionally. So, I thought it appropriate to revisit the way we approach our work and talk a little about ethics.  Read More "The Ultimate Standard"

A Tree Selection Survey of Tree City USA Designated Cities in the Pacific Northwest

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

Editor’s note: This article is a follow-up to one published by the same authors in the Winter 2020 edition of PNW Trees.

Urban sprawl and development can lead to a reduction in the canopy volume of urban trees, which reduces the benefits provided by those trees. When selecting tree species for urban areas, carefully considering the site criteria can lead to greater benefits and longer-lived trees. Selecting a diverse array of trees contributes to urban forest diversity which can help avoid catastrophic tree losses due to pests and climate change.  Read More "A Tree Selection Survey of Tree City USA Designated Cities in the Pacific Northwest"

Sooty-Bark Disease of Maple

In February and March of 2020, samples taken for DNA Sequencing from a declining Sycamore maple (Acer pseudoplatanus) and red maple (Acer rubrum) in Seattle, Washington came back positive for Cryptostroma corticale, also known as Sooty-Bark Disease. This is the first time this disease has been found in red maple. 

Sooty Bark Disease attacks and kills the cambium and bark of infected trees resulting in canopy decline and eventually death. This pathogen is from northeastern America where it does not cause disease. It was introduced to Europe where it has caused a disease in field maple (A. campestre), Norway maple (A. platanoides) and box elder (A. negundo).  Read More "Sooty-Bark Disease of Maple"

With much of our work being restricted heavily due to COVID 19, we have had an unusual amount of time to refocus and allocate our efforts. I have been studying tree care standards and research to help develop new marketing material for areas of practice that I haven’t focused on in the past. For me, as I delve into this marketing project I keep coming across research that was supported by the TREE Fund. This is a great reminder to me of how integral the TREE Fund is in furthering the professional practice of arboriculture. Much of the published work funded by TREE Fund is available in the ISA’s Journal of Arboriculture and Urban Forestry. Read More "What’s New with the TREE Fund?"

Greetings from the Canadian TREE Fund 

There is no doubt that we are all facing the most challenging times that we have ever experienced. Along with the likes of the Great Depression (4 years), WW1 (4 years), the Spanish Flu – 1918 (2 years), WW2 (6 years) our current crisis threatens our well being on many levels. We are just four months into this and there’s strong evidence that our daily sacrifices are saving lives as we forge onward into this new "normal". Read More "Greetings from the Canadian TREE Fund "

ATC ’20 Becomes Virtual Conference

Over the past six months, I have worked alongside Katie Kosanke and Angel Spell, chairs of the Annual Training Conference '20, Canopy Connections: Advancing Equity, Wellness & Community in Arboriculture. It has been a joy to watch this year's ATC committee identify educational topics, select quality speakers, determine what type of fun, engaging activities and events they want to offer members and guests, and overall, work together as a team. That's why the last couple of weeks were particularly difficult as the committee weighed the pros and cons of hosting ATC '20 in a COVID-19 environment. After many discussions, the committee and board of directors made the decision to prioritize the health and safety of members and guests by replacing this year's in-person conference with a virtual conference instead.

Mistaken Identity or Identity Crisis?

Executive Director
Learn more about Cristina Bowerman.

If the COVID pandemic has taught me anything it’s that many lawmakers in our region are unfamiliar with our industry and what we do as professionals. Since mid-March when executive orders were enforced, we have been left to interpret what categories of essential work, if any, our industry and professions fall in.

For example, Alaska’s executive order made no reference to arborist related trades, only loggers. Idaho identified landscapers and while Washington specified arborists and forestry, it combined them with construction trades. British Columbia left plenty of room for interpretation with broad categories for infrastructure and non-health essential service providers. And, Oregon remained unique in its stance by not providing an essential businesses list but emphasizing that businesses could remain open if social distancing, hygiene and sanitation guidelines were met.
