Helping Oaks Helps Birds

In January some of our members attended a presentation on the importance of native plants by Doug Tallamy and heard an array of speakers at the Willamette Valley Bird Symposium. Although there were many synergies, one stood out—discussions on the importance of oak trees. Often dubbed the “Mighty Oak,” oak trees usually do stand out with their majestic growth, welcome shade, and ability to host so many organisms.

Considered a keystone species, they have a disproportionately large impact on the ecosystem and are of critical importance to a diverse group of animals including many bird species. Oaks provide food, shelter, and nesting sites for birds. They sequester carbon and aid the watershed with their big canopies and extensive root systems. Their leaf litter protects critters that live in the soil while slowly nourishing that soil as it decomposes. Considered the most productive plant in this country, oaks support more than 900 species of Lepidoptera—butterflies and moths. Their caterpillars are often the primary food source for spring nestlings. Plenty of other insects are supported by oak trees, which, along with their acorns, provide a buffet for birds and other wildlife.

Oaks have been reduced to approximately 25% of their historic range in Oregon and only 10% of their historic range across the Pacific Northwest. Let’s reverse that trend.  Plant and protect Oregon White Oak trees. Support oak savannah restoration projects. Advocate for oak-friendly management practices and conservation of oak savannahs.  Check out the ten ways we can help oaks at The Decade of the Oaks, an education program in our area
