Oregon Nature Events
Seasonal festivals and wildlife events in Oregon — tied to the same ecological rhythms this calendar tracks.
Hoyt Arboretum Spring Equinox Walk
Educational guided walk through Portland's 190-acre tree museum at the spring equinox — 12,000 trees beginning their spring flush, ephemerals at the woodland edge.
Trillium Festival at Tryon Creek
Portland's beloved trillium celebration in one of the city's only remaining old-growth forest corridors — native plant sale, forest walks, and wildflower viewing.
Camassia Natural Area
One of Oregon's best wildflower viewing sites — a rocky basalt plateau with 300+ plant species including camas lily, blue-eyed Mary, and rosy plectritis.
Camas Festival at Linfield University
An Indigenous-centered celebration of the camas flower in partnership with the Confederated Tribes of Grand Ronde — guided tours, marketplace, art exhibits, and cultural talks.
