Workshop

Description

Street Tree Pruning

Learn to prune young street trees for structure and health alongside a certified arborist. Together, your team and volunteers will prune over 100 trees during this event! 

Tree Planting

Plant 5-10 trees at a school, community center, church, or park. Staff will help guide you to create a planting and establishment plan and provide all trees and tools.

General Tree Care

Learn to care for your tree from planting through replacement. Topics covered include watering, mulching, pruning, and recognizing problems. Learn when to call a professional and how to evaluate potential tree care providers’ credentials. 

Pests and Pathogens

Learn to recognize common pests and diseases in your street trees and methods to mitigate their spread. Some events focus on a specific pest or pathogen such as Dutch Elm Disease, Emerald Ash Borer, or Asian long horned beetle.

 Heritage Trees

Portland’s Heritage Tree Program celebrates the largest, oldest, most historic, and unusual trees in the city. Visit Heritage Trees in your neighborhood and learn their stories. If your neighborhood does not have any Heritage Trees, use inventory data to find the largest and most unusual trees and visit them to determine if they should be nominated for the Heritage Tree status.

 Tree History in Your Neighborhood

Work with a historian to research and learn about the trees in your community and how past development shaped the community’s urban forest. Understanding and valuing trees historically leaves us better equipped to make future decisions and avoid unexpected consequences inherited from our past. 

Invasive Trees - Wrong Tree, Wrong Place

What trees don't belong in your neighborhood? Fast-growing invasive tree species thrive in tight locations and may quickly damage habitat or existing structures. Learn which tree species are nuisances or invasive in Portland, how to identify them, and the best strategies for their control.

 

Selecting and Promoting Diverse Tree Species

What to plant? Flowers, fall color, fruits/nuts for wildlife, and winter interest are just a few characteristics to consider when choosing a tree. Explore interesting species and learn why tree diversity is important for a resilient forest. Part discussion, part discovery, this workshop will get community members excited about the various trees that can be grown in our region.

Spring or Winter Tree Identification

Our ID expert will teach your group how to use leaves, fruit, bark, and flowers to identify species, how to use a dichotomous key, and how to collect and preserve samples with a DIY plant press. Take your tree identification skills to the next level during the winter, where you will learn how to identify trees without their leaves using buds, bud scars, twigs, bark, branching patterns, and other clues. 

The Benefits of Trees

Trees provide numerous benefits in an urban setting. Using a prominent park or community location, calculate the environmental and aesthetic benefits of key trees. Values will be displayed on trees using large tree “price tags.” This eye-catching display is an excellent method for raising awareness about trees and recruiting participation in the local Tree Team.

Decoding Portland's Tree Code

On January 2, 2015 Portland implemented a new citywide Tree Code. How does this updated code protect trees and impact property owners? Learn about the updated regulations behind tree planting, pruning, and removal, tree protection and planting requirements during development, and new resources available to residents.

Heritage Trees

Portland’s Heritage Trees Program celebrates the largest, oldest, most historic, and unusual trees in the city. Visit Heritage Trees in your neighborhood and learn their stories. If your neighborhood does not have any Heritage Trees, use inventory data to find the largest and most unusual trees and visit them to determine if they should be nominated for the Heritage Tree Program.
