2021 Lake Oswego Tree Summit

On Saturday, October 30, 2021, stewards of our urban forest in Lake Oswego participated in this community-led Zoom event to celebrate trees and the ecology of our Urban Forest. This was the third annual Tree Summit.

The keynote speaker was Dr. Christine Buh, state Forest Entomologist with the Oregon Department of Forestry. There was also a presentation of the most recent lidar analysis of the Lake Oswego forest canopy given by the  City of Lake Oswego. Breakout groups discussed (their answers captured below):

  • What are the impacts of recent weather events?
  • How do you think you personally can use the information from Dr. Buhl’s presentation to help address these challenges?
  • What are your initial thoughts about the LiDAR information? How can we use this info to help us sustain our urban forest?

The Tree Summit is presented in partnership with the Oswego Lake Watershed Council and the Lake Oswego Sustainability Network. Thank you to Clackamas Soil and Water Conservation District for helping to fund this important work!

Thanks to all who participated in this event to enhance your arboreal knowledge and discover ways to connect with and enhance the ecological health of our urban forest.
