Volunteer

Join Friends of Tanner Springs year-round as we restore the oak-prairie habitat at Tanner Springs Park in Portland’s Pearl District. All you need is a pair of garden gloves. We have the tools.  If you don’t know much about oak savannas, upland prairies or plants in general, don’t worry.  We’ll teach you.  Our projects are tied to the seasons…

Native and Nuisance Plants

Exploring the Portland landscape is a visceral experience of the natural heritage thousands of years in the making. Rocky buttes cloaked in forest and prairie dapple the urban boundary. Streams and rivers flow by parks, private homes, and city tree canopies.  The plants in these habitats support the life around them. The City of Portland recognizes the importance…

Cultivating Curiosity and Stewardship

WELCOME TO TANNER SPRINGS PARK, an urban oasis of oak-prairie and wetlands – a microcosm of the richness that the Willamette Valley once held. Less than 5% remains of the original 1.7 million acres. We hope you enjoy the smorgasbord of over 72 species of native plants providing a continuous food buffet for native pollinators…

Restoring Oak-Prairie

A bird’s eye view of the Willamette Valley  10,000 years ago would have exposed a matrix of  oak-prairies throughout the region. Now only 5% remains–a national assessment identified it as one of the United States’ most endangered ecosystems. An oak-prairie habitat hosts a significant amount of biodiversity of both flora and fauna. A healthy ecosystem could…

Blues and our Great Blue

The Great Blue Heron’s tall silhouette in the pond barely moves for hours. It waits patiently for its prey to swim in and out of the pond shadows. Looking for the shimmer of fish, then, it darts its dagger-like beak forward. Harpooning prey and swallowing it whole. Sometimes you can watch the unfortunate, slowly slide down the…

Stepping Stones for Wildlife

2018 Ducklings at Tanner Springs Park Our stepping stone park has been home to another clutch of Mallard ducklings. In spring ten ducklings hatched of which 8 survived. Their mother’s rigorous Barre3-style exercises on our steps prepared them for their departure from the park.  In the middle of May they left for adventures and parts…

More Milkweed for Monarchs

At Tanner Spring Park we are hoping to expand the Western breeding habitat for Monarchs by increasing Showy Milkweed. Monarchs migrate through Portland, as well as the northern Oregon coast but have not found significant host plants to breed. We are hoping to change this. The park is part of a national campaign to support the Monarch Butterfly (Danaus plexippus)…

Rewarding Community Day

Parke Diem brought our community together for a successful planting despite weather setbacks and rescheduling. Friends of Tanner Springs Park,  Portland Parks and Recreation employees and new volunteers extended our mosaic of native prairie grass and perennials. Tufted Hair Grass was interwoven with Oregon Sunshine,  Slender Cinquefoil and Douglas Iris. Under our Oregon White Oaks we…

Our Heritage Park

Tanner Springs Park is the expression of a Portland community’s sense of place through reconnections with nature and history. A contaminated city block is transformed into a tranquil park with oak-prairie and recirculating wetland. The endangered oak savanna and upland prairie habitat of the Willamette Valley with its natural sloping characteristics to lowland wetlands is recreated here. Oregon White…
