ANLD/APLD Joint Program

ANLD/APLD Joint Program

Trees are the largest plants in a garden. As we've experienced this winter, the forces of Nature sometimes cause them to fall down and create considerable havoc. This program give designers the latest information, allowing them to make decisions about a tree's existing conditions in the field as well as those made about new trees at the drafting board. The result: your happy clients will have trees that will thrive long into the future. This program promises to fill you in on the latest information about trees – which is in the process of changing rapidly due to new research as well as inform designers about code constraints in an urban setting. Finally, our own Sean Hogan promises to teach us about some of the best small urban trees. You will not want to miss this program! Registration DEADLINE: March 29, NOON!

9:00: SCOTT CLIFTON, Identifying Hazardous Trees

Scott is the recipient of the ISA 2013 Tree Worker of the Year award, is an ISA Certified Arborist as well as an ISA Certified Utility Specialist, Tree Worker Aerial Lift Specialist and has ISA Tree Risk Assessment Qualification and Certification Proctor. He is a graduate of the American Society of Consulting Arborists Academy and has ArborMaster training.

10:00: break

10:30: Catherine Mushel, Working With the Tree Code: Stewardship/Ownership
Catherine Mushel's love of trees began as a child in the woods of northwestern Montana. Twenty-two years ago, after moving to Portland, she joined Friends of Trees. Her involvement began simply with planting trees before she became a planting coordinator in her own neighborhood as a trained Urban Forestry Tree Steward. Prior to being appointed to the Urban Forestry Commission in 2011, she helped coordinate pruning the neighborhood linden alleé, and how Catherine works with fellow commissioners to represent the public's voices and advise the city forester and city council on forestry issues.

Catherine's talk will address the aim of discovering where private and public practices and interests are aligned and where professional designers might have a unique part to play in the stewardship-ownership dialogue. She will also address how designers can work with Portland's urban tree code.

11:30: Sean Hogan, The Best Small Urban Trees
Sean Hogan is the owner of the renowned Cistus Design Nursery in Sauvie Island, OR. Besides introducing many new plants to U.S. gardens, Hogan also designs innovative gardens and collaborates with architects and designers on horticultural aspects of their projects. Sean has a curatorial and collections background at the Hoyt Arboretum in Portland and the University of California Berkeley Botanic Garden. He has traveled all over the world to collect plants with potential application in U.S. landscapes and has managed the design of naturalistic landscapes, eco-roof installations, and water conservation gardens. One of his major horticultural interests is promoting new, underused, and unknown plants for summer-dry climates.

Sean will show us some of the best trees for use in smaller urban gardens, around pesky power lines, and after this winter, trees that succeed under extreme weather conditions.

12:30-1:00: Panel will respond to questions.
