Tree Protection During Construction
This workshop has reached capacity. Select REGISTER NOW to join our waitlist. We will be in touch if a spot becomes available.
Trees are commonly damaged during construction and successful preservation requires special consideration. This comprehensive workshop explores strategies for managing trees during construction through all phases of development. Learn about:
- The value of preserving existing trees with development;
- The importance of the arborist’s role throughout project planning, design and construction;
- Identifying trees that are suitable for preservation;
- The possible ways trees may be affected by construction;
- Tree protection measures and monitoring;
- The use of alternative construction techniques to provide for tree protection; and
- Addressing tree damage, risk potential and remedial treatments.
This workshop is suitable for arborists and professionals of all levels but is targeted to arborists with limited experience in offering consulting services related to tree preservation or construction monitoring, landscape architects who coordinate with project arborists or design with existing trees in mind, and municipal and agency staff members that review and enforce tree protection plans.
Includes an indoor presentation and outdoor exercise.
