Tree Risk Assessment Workshops with Ed Hayes, Safe Trees, LLC

My workshops include classroom presentations and a hands-on outside field exercise. Continuing education credits are available from the ISA and other organizations depending on the state or country. These credits generally range from 6-7 per day. There are options for one or two day workshops that always include at least a half-day field exercise. Additional time may be needed to include tree dissections as this would involve additional resources. A workshop can be tailored to fit your needs.

Available workshops;

1. Basic to advanced Tree Risk Assessment with an afternoon field exercise (1 day).

2. Basic to advanced Tree Risk Assessment with a ½ day tree dissection workshop (1½ days).

Agenda 2014 and beyond;

Tree decay, modes of failure, and species profiles.

Tree mechanics, vector forces, attributes if wind loading and responsive growth.

Break; mid-morning around 9:45am.

Evaluating decay above and below ground.

Tree Defects, assessing the "Likelihood of Failure".

Mitigation options and examples in practice.

Lunch; noon until about 12:45pm.
