Oregon White Oak (Quercus garryana) and Our Watershed

Oregon white oaks are a keystone species in our local landscapes, supporting healthy watersheds, wildlife, and communities. Their deep roots stabilize soil and filter water, helping maintain clean streams and rivers. Upland oaks provide essential habitat for hundreds of bird, mammal, and insect species, while also supporting rare plants and pollinators. Protecting and restoring these trees is critical for resilient ecosystems and the health of our watershed.

Why Oaks Matter to the Watershed

• Water Quality: Oak roots reduce erosion and help filter stormwater before it reaches streams.
• Wildlife Habitat: Oaks provide food and shelter for birds, mammals, and pollinators.
• Biodiversity: Oak ecosystems support a diverse understory of plants and other native species.
• Cultural Significance: The First Stewards of Oregon white oaks recognized their importance for food, materials, and cultural practices. Today, we continue to honor and learn from their stewardship.
• Community Connection: Oaks offer educational opportunities and connect people to the land through stewardship and restoration.
