Tree Growth & Development: What Arborists Need to Know

Date: May 17, 2018
Location: Washington Park Arboretum, Seattle, WA, UNITED STATES
Organizer: Pacific Northwest Chapter of ISA
Sponsor: Pacific Northwest Chapter of ISA
Description: Understanding how trees grow is a foundation for the practice of arboriculture. However, if one picks up a current article about woody plants, one can be overwhelmed with jargon (determinate, indeterminate, apical dominance vs. apical control, isohydric and anisohydric responses to water stress, embolism, cavitation, hydraulic redistribution, hydraulic architecture, hydraulic vulnerability, carbon starvation, role of aquaporins in membrane function, …). Is it all garbage or can you improve your understanding of trees by having these terms explained?

This course, taught by Tom Hinckley, UW Emeritus Professor of Woody Plant Physiology, will cover the basics of tree biology and how trees grow in response to their environment. Topics to be covered include meristems and their functions, growth patterns, tree responses to stress, tree competition and mortality, and how trees get water from roots to their canopies. The class includes a lecture plus hands-on examples with whole trees and tree parts from a range of circumstances and species. We will put current concepts of tree growth and development into a form that arborists can use in their work.

Tom Hinckley studies tissue to whole tree responses to environmental stresses. He is particularly interested in the water and nutrient relations, carbon economy, and growth of trees from diverse ecosystems. Recent emphases have been on the understanding of structural-functional relationships using Populus as a model system, and on scaling leaf and twig level measures of water loss to the branch, tree, and stand levels in such species as hybrid Populus, Abies amabilis, and Pseudotsuga menziesii. For the latter species, he has been using the Wind River Canopy Crane Research Facility.

Cost of course includes a 20 page color book.
