PNW-ISA Annual Training Conference 2017–People & Trees: Adapting to Change

Lynnwood Convention Center & Lynndale Park, Lynnwood, Washington

As the old saying goes, nothing remains constant except change itself.  Adapting to change is the cornerstone to survival and success.  Having the right information is essential to the choices and changes we make as professionals.

In current times, it seems that the rate of change in the world is greater than it's ever been. In the practice of arboriculture, trees and the people who care for them must navigate a variety of changes from different sources.  This year's conference will explore topics in tree science, as well as social and environmental changes that influence tree care practices.

Tree Academies, Sunday, September 24

Tree Academy #1: Diagnosing Tree Pathology

Presented by Sharon Collman, Amy Ramsay and Glenn Kohler
9 AM – 4 PM at McCollum Park, Lynnwood, WA
6.0 ISA CEUs pending approval

This academy is designed to improve diagnostic ability of arborists managing trees within their jurisdiction. We will focus on the less understood and recognized insects and diseases. Specifically, we will address invasive species to watch for (as early detection can minimize their regional spread and impacts), wood borers recognition and understanding their economic impacts and environmental benefits, and tree root, butt and heart rots. The format will be lecture, interactive lab specimens, field walks, and an IPM exercise.

Join us for a packed day of learning and connecting with other arborists. Meeting new colleagues and building networks is an important component of the day. This academy will be held at McCollum Park, a great laboratory for tree evaluation and samples of insect and disease problems (even some beaver damage).

Tree Academy #2: Trees and the US Law

Presented by Jim Flott and Thomas Miller
9 AM – 4 PM at Lynnwood Convention Center, Lynnwood, WA
6.0 ISA CEUs pending approval

Sooner or later, one of your clients will have a legal dilemma involving a tree. The purpose of this seminar is to provide you with a framework to analyze the situation and decide if you are qualified to handle tree law cases.

The presentation will include statutory enactments in Idaho, Oregon, and Washington affecting trees and development laws including those involving adjoining landowners, logging, timber trespass, public utilities, governmental police powers, governmental liability, trees and roadways, the rights and responsibilities of landowners, duty of care, negligence, and damages. The presentation will specifically include measures of damages for damage to or destruction of trees.

Tree Academy #3: Urban Street Tree Plantings

Presented by Jim Barborinas and Martin Hanni
12 PM – 4 PM at Urban Forest Nursery, Mt. Vernon, WA
3.5 ISA CEUs pending approval

Join Jim and Martin as they expand your tree planting palette. Walk and talk as they share lessons from the nursery. Participants will leave this workshop inspired and prepared for their next tree planting project.

Seating is limited for this Tree Academy. Plan to register early. Also, please note the location. Urban Forest Nursery is a two-hour drive north from the Lynnwood Convention Center.

Field Day at Lynndale Park, Monday, September 25

How do you look at a tree?  - Led by instructor teams with experience in tree assessment and climbing, these sessions will cover aspects of Visual Tree Assessment for different objectives, including tree health diagnostics, risk assessment, and appraisal as well as pre-climbing tree inspection.

Tree basics - Planting, Understanding Soil, Tree ID, and Structural Pruning - Instruction and demonstrations will provide great review and introductory information for those new to the field or preparing for the Certification exam.

Climbing tools and techniques - Throwline tips and techniques, Single Rope Technique, Traversing trees, and chainsaw safety.

Pull-testing demonstration - advanced diagnostic testing for tree stability.

ARC Truck - electrical safety training and demonstration station.

Utility corridors - Management of trees and other vegetation along corridor edges.

Trees and the Livable City: From Sanitary to Sustainable

Dr. Kathleen Wolf, Research Social Scientist, University of Washington College of the Environment

Dr. Kathleen Wolf is a Research Social Scientist at the College of the Environment, University of Washington. She is a research associate with the US Forest Service Pacific NW Research Station on urban forestry studies. Dr. Wolf's research explores the human dimensions of urban ecosystems. She has also worked professionally as a landscape architect and as an environmental planner. Kathy's professional mission is to discover, understand and communicate human behavior and benefits, as people experience nature in cities and towns. Moreover, Kathy is interested in how scientific information can be integrated into local government policy and planning. She has served with national organizations that promote nature in cities, such as the Transportation Research Board national committee on Landscape and Environment,  the Sustainable Sites Initiative, and the TKF Foundation.

Witness Tree: Seasons of Change with a Century-Old Oak

Linda V. Mapes, Seattle Times Environmental Reporter and Author

Lynda Mapes is a longtime reporter for the Seattle Times, covering the environment and natural history, including the removal of the Elway River Dams. She is author of four books, Elwha- A River Reborn, Breaking Ground: The Lower Elwha Klallam Tribe and Unearthing of Tse-Whit-Zen Village, Washington: The Spirit of the Land, and most recently, Witness Tree: Seasons of Change with a Century-Old Oak. In her new book Witness Tree, Lynda tells the story of climate change through the life of a single 100-year-old red oak tree in the Harvard Forest. She will share the story of what she learned during the year she spent at there as a Bullard Fellow in forest research in residence, exploring the human and natural history of a single tree.
