OCRF Grant Protects Lake Oswego Oaks

Our Oregon White Oaks (Quercus garryana) are special trees. They represent strength and continuity and need to be celebrated and protected. OLWC has just received a grant from the Oregon Conservation and Recreation Fund (OCRF) to support oak woodland enhancement in the Westlake area. Included in the grant is funding to develop messaging for our community about our native oaks and how they were used and protected by indigenous people prior to colonization. You can learn more about OLWC’s oak enhancement project here.
