How to Manage and Prune Trees for Wildlife (CANCELLED)

July 10 @ 8:00 am - 4:00 pm
Instructor: Brian French and Ryan Gilpin CEUs: 7.0 AMU | 2.25 LT | 0.5 B-S, 1.75 B-P, 4.75 B-M

This workshop has been cancelled due to COVID-19.

In recent years, the tree care industry has embraced many practices regarding wildlife. This workshop provides attendees a review of the newly updated ISA Pruning Best Management Practices (BMPs) recommendations for inspecting nesting wildlife. The new ANSI A300 Pruning Standard lists “managing wildlife habitat” as an objective.

This workshop will train participants in:

  • Navigating the ISA Pruning BMPs that will help minimize impacts to nesting wildlife.
  • Best Practices for safely creating habitat using urban forestry.
  • How to conduct a habitat inspection, including determining habitat value, conducting pre-work nesting surveys, identifying signs of nesting wildlife, determining if nests are active, responding to wildlife emergencies and contacting wildlife biologists when needed.

This 8-hour workshop will involve approximately 60% indoor, classroom instruction and 40% outdoor, hands-on training. Outdoor portions will focus on habitat analysis, pre-work inspections, coronet cuts and artificial cavity creation. Please bring your PPE and hearing protection.

Workshop instructors have been working with the Western Chapter of the ISA to develop BMPs for the tree care industry regarding wildlife. The instructors bring contrasting perspectives to the workshop.  Brian is a climbing arborist in Portland with a background in traditional arboriculture. Ryan is a consulting arborist in the San Francisco Bay Area with a background in ecology and conservation.
