A walk through Cooper Mountain Nature Park


Cooper Mountain Nature Park is a natural bridge between dense urban landscapes to the north and agricultural lands to the south. Its 231 acres and Nature House are home to tours and classes throughout the year. Three miles of trails traverse the park, passing through varying habitats and offering views of the Chehalem Mountains. Dogs are not allowed. The park is open daily dawn to dusk.

Amid the suburban landscapes of Beaverton, I stood on the urban growth boundary, overlooking agricultural lands from greater Portland’s newest nature setting, Cooper Mountain Nature Park.

At the park, three miles of trails beckon, with varying difficulty through three distinct habitats - forest, prairie and oak woodlands. Because we had only an hour to experience the park, we chose the shortest trail, which we didn’t complete because we stopped every few feet to admire and drink in the scenery.

My journey along the gravel trail proved to be highly educational. My group spotted native plants and identified invasive species. We discovered a couple of Bitter Cherry trees, which provide nourishment to various birds and wildlife, and a lone St. John’s wort plant, which is used as an herbal treatment for depression. We discovered mole holes and squirrel nests, while a chorus of musical chirps from the birds welcomed us through this new suburban oasis. One of the ecological virtues of Cooper Mountain Nature Park is the Willamette Valley Ponderosa Pine, which is being reintroduced after nearly disappearing due to years of logging and urban growth.

Our hour-long walk provided a much-needed respite from the hustle and bustle of the day. Had it been the weekend, I would have stopped at nearby Cooper Mountain Vineyards for a glass of Pinot Gris. Perhaps next time.
