Date and Time:
March 18, 2013
8:00 am - 4:00 pm
Attendance is limited to 100 participants.
• Hands on practical approach to pruning • How to reduce risk in mature trees • How to develop structurally sound branch architecture • The latest in tree biomechanics and stability • How to write meaningful pruning specifications
From training young trees to managing mature ones, structural pruning to guide and manage tree architecture should be the primary goal each time a tree is pruned. We will show you how to create a well-structured tree that is aesthetically pleasing and supports the crown so it grows old gracefully. This ensures that the tree will provide the greatest benefits at the lowest cost.
Purpose: The purpose of the workshop is to describe and demonstrate current structural pruning strategies to improve architecture on young,
medium-aged, and older trees. We will focus on the long-term response of trees to pruning and show many real-world examples from California and across the world. We discuss not only what and how to improve structure and reduce the likelihood for failure, but also how the tree is likely to respond, incorporating current tree biomechanics research and experience. Learn how to incorporate accountability when writing pruning specifications.
Program: This is an interactive hands on program where you will watch a tree being pruned and provide input. Active participation is expected of attendees. There is ample time to evaluate the trees we structurally pruned one year ago at the same sites and discuss their response. Additional trees of various sizes will be pruned in the field.
Instructors: Brian Kempf and Ed Gilman
8:00 am Registration
8:30 am Welcome and Introduction
We will start with the basics and move into advanced techniques used to structurally prune trees. We will describe lessons and mistakes made in the last 15 years of pruning trees.
9:00 am Biomechanics and the Science of Tree Structure Sells Tree Work
We will focus on practical experience of many arborists, and the applied research that supports structural pruning as the heart of risk reduction strategies.
10:00 am Break
10:15 am Pruning Methods That Improve Tree Structure
Pruning practices appear to be based more on culture and tradition of tree care in a region than other factors. Adoption of well written specifications can advance our professionalism by clarifying customer expectations.
10:45 am Evaluate Trees of Various Ages in the Field Pruned Last Year
In-field inspection of trees pruned last year will show us all how trees responded to pruning methods applied to a variety of shade trees.
11:45 am Questions and Answers
12:00 pm Lunch
1:00 pm Outdoor Hands on Structural Pruning Exercises on Young and Old Trees
Pruning the correct live branches can have a dramatic impact on how trees respond to gravity and storms.
3:30 pm Discussion of Day’s Experiences and Pruning Recommendations
