Giving Trees a Second Life: Managing Urban Habitat Trees @11:00 Mountain
Dead, dying, and decaying trees are usually seen as urban forestry liabilities—but they are also some of the most valuable wildlife habitats in our cities.
Join us for Giving Trees a Second Life: Managing Urban Habitat Trees to explore how habitat trees support biodiversity and provide critical shelter and food sources for urban wildlife. From legacy trees to fallen logs, discover how habitat value increases with tree age.
We will examine practical strategies for managing habitat trees in urban environments while balancing public safety, risk management, and community education. Learn how arborists and urban forestry professionals can integrate wildlife value into tree risk assessment and long-term management decisions, including innovative techniques such as fracture pruning, coronet cuts, artificial cavities, and the strategic placement of dropped logs. Gain insight into national conservation programs that bring people together to create healthier communities – and important role of urban trees.
Whether you are developing habitat-focused management policies or looking for practical field applications, this session will provide actionable tools and fresh perspectives for creating more ecologically resilient urban forests.
Register today and discover how trees can continue to serve their communities long after decline begins.
Thursday
The Science Behind Tree Growth Regulators @ 10am Mountain
Curious how tree growth regulators work their magic? This session breaks down the fascinating science of paclobutrazol (The most common used TGR) revealing how it changes trees from the inside out and what those changes mean in the real world. Get ready for eye-opening examples and practical applications you can use in your own tree care.
Urban Wood: Where Opportunities and Traditions Meet @ 10am Mountain
The use of wood from urban and community forestry operations is emerging as an opportunity to utilize “waste” to create products and jobs while activating relationships with the people we serve. These materials also connect us to the land, history, and sustainable practices. Join us to see how putting urban and community wood to best use can strengthen your efforts towards resilient and equitable management.
American Elm Tree Resistance Breeding and Restoration @ 11:00 am Mountain
The US Forest Service and partners are breeding American elm trees with resistance to Dutch elm disease. Hear the latest updates from resistance trials and progress on seed orchard plantings.
Dr. Kathleen Knight is a research ecologist with the US Forest Service Northern Research Station. She co-leads the American elm breeding program and studies impacts and management of emerald ash borer.
Manage the Threat: Emerald Ash Borer in New Markets @2pm Mountain
Emerald ash borer is still spreading into new regions across United States. For professionals facing this problem for the first time, we will review how the insect moves to new territory, reproduces, and kills ash trees. We will also cover insecticides, equipment, and general strategies for executing a treatment plan that limits the spread and protects valuable trees. The 45-minute presentation will be followed by 15 minutes of Q&A.
