    Equity in Our Urban Forests - What does it mean and why does it matter?

    The Nature Conservancy produced this insightful video highlighting the vital role of urban trees in promoting climate resilience and community well-being. While the case study focuses on Denver, Colorado, the concepts are just as relevant to communities here in Southern Oregon.

    The video explores the many benefits of urban trees, from cooling neighborhoods and improving air quality to advancing environmental justice. Learn about urban heat islands, the importance of equitable canopy coverage, and how the City of Denver is working to restore its urban forest.

    Why we don’t plant Ash trees: Learn about the Emerald Ash Borer (EAB) and How to Protect Our Ash Trees.

    The emerald ash borer (EAB) is an invasive beetle that poses a serious threat to ash trees across Oregon. Due to the growing threat of EAB in our region, OUR Community Forestry does not plant ash trees as part of our tree planting programs. Prioritizing tree species that are more resilient to pests and disease helps us build a healthier, longer-lasting urban forest.

    To support community awareness and early detection, we’ve included links to pocket guides, available in both English and Spanish, to help you identify ash trees and learn steps you can take to help protect them.

    For more detailed information, including how to identify EAB, recognize signs of infestation, and report sightings, visit the EAB information page.

    The Oregon Department of Forestry has also created a short, informative video that explains what EAB is, how it spreads, and the potential impacts on urban forests titled "Urban Forestry: Emerald Ash Borer Informative Discussion".
