Transition Update

In February 2019, the Board of Directors reviewed the results of an Organizational Assessment completed by Loveall Price & Associates, a nonprofit transitional consulting firm. The Board accepted the recommendations in the assessment, including initiatives to update operational systems, and move towards a virtual office for the Chapter. Staff have been working diligently to implement those recommendations.

PNW-ISA has retained Loveall Price and Associates to assist with an Executive Director Search that will commence later this summer.  We will hire a new executive Director for the Chapter by the end of 2019.

Learn more about Melissa Amrhein.

PNW-ISA hosted its second successful Women’s Tree Climbing Workshop on June 7-9, 2019 in Seattle, WA. International Tree Climbing Championship competitors Bear LeVangie and Melissa LeVangie flew in from the east coast to teach along with a top notch instructional team including Rebecca Seibel-Hunt, Kate Tarkington, Jamilee Kempton, Kali Alcorn, Krista Strating and Maria Tranguch. The group was engaging, enthusiastic, genuine and knowledgeable. What a team!

Participation was diverse. Women traveled from out of state and out of country to participate. Experience levels ranged from no previous climbing to those that wanted to improve specific skills. Every participant made big leaps towards their goals. It was empowering to observe the transformations that occurred in such a short period of time.

The Cities of Boise, Caldwell, Eagle, Kuna, Meridian and Nampa, Idaho are proud of their trees! It was with this sentiment of value and appreciation for our trees that the TV Tree Selection Guide was created. Based largely on the original version from the Boise Parks & Recreation Department’s Tree Selection Guide developed by the Urban Forestry Unit in 1995, the new guide was fashioned.

It was time…time to broaden tree species selections to include new cultivars. And, remove old ones that were not performing well. This was a labor of satisfaction for everyone involved. Read More "Treasure Valley Tree Selection Guide: A Process of Transformation"

The PNW class “Common Fungi Affecting PNW Trees and Implications for Tree Risk Assessment” was a classroom/outdoor course in tree diseases, and particularly anyone conducting risk assessment of trees with disease.  Led by Dr Julian Dunster and Professor Bob Edmonds.

The diseases covered included Phaeolus schweinitzii, Heterobasidion occidentale, Armillaria ostoyae, Porodaedalea pini, Kretzschmeria deusta, Phellinus sulphurascens, Neofusicoccum arbuti and others.

Morning lectures covered visual assessment techniques for disease, using a combination of signs and symptoms of common diseases in native PNW trees. Sonic tomography and resistance drilling will be discussed as examples of advanced risk assessment techniques.

The afternoon was spent outdoors examining diseases of Douglas-fir, western hemlock, western red cedar, bigleaf maple, and Pacific madrone. The types of wood decay, fungus fruiting bodies, as well as structural and risk implications will be covered.

The PNW is grateful to have Roger Barnett attend, to learn and capture moments on digital film for all to take a peek into this course.  Please see some of these moments on this flicker account below:

We porta-wrapped up the PNW TCC 2018 with huge success! PNW-ISA hosted the event in beautiful Vancouver BC at Stanley Park. To see familiar faces, shake new hands, and share stories with each other is such a gift. Our Chapter continues to progress and expand into a new and bright canopy of good tree people. Without all the support from our membership, these educational events and skills competitions would senesce. Enjoying the aerial feats of strength and agility is mesmerizing, and it is an amazing opportunity to show the public how we use rope access to manage their trees, and have fun at work.

Last summer, the Guide for Plant Appraisal 10th Edition finally reached our industry. Long promised and fiercely debated, it addresses several changes in our systematic approach to placing a value to a tree. The new guide weighs looks, feels, and reads similar to the tree risk assessment manual. And this was intentional. As stated in the preface of the manual itself:
