The Harrison Ridge Greenbelt: A History of Community Activism, Chapter 4


“Hey! What are you doing tearing out the blackberries!??” Trina and I turn smiling to look upon a young woman walking her dog. I gesture to the sign describing the park as a reforestation site. “We’re your neighbors and the volunteer forest stewards for our Greenbelt. It’s important to remove the invasive plants so that the park will survive.” “But I like blackberries!”, she insists. It’s getting harder to find them in the city. How will I have my blackberry pies? Why can’t the park just be natural?”

This type of encounter is common for forest stewards throughout the city. It’s music to our ears to hear that folks are having a harder time finding blackberry patches. Blackberry is among the most invasive species killing our parks. Without restoration, it’s estimated that in 50 years all the trees will be gone and by the end of the century, Seattle’s urban forests will be completely destroyed. All that will remain will be ivy deserts and impenetrable blackberry thickets. It’s a desirable habitat for rats but not for many other creatures, including humans.

Today, Seattle’s urban forests are predominately deciduous trees such as big leaf maples and alders nearing or at the end of their lifespans. They are infamous for chucking off limbs in windstorms or falling down completely creating hazardous conditions. Additionally, they are covered with an ivy and clematis canopy hastening their demise. Although green in summer, they are extremely unattractive in winter. These neglected green spaces are undesirable.

Healthy urban forests are attractive and increase property values. They provide wildlife habitat, reduce storm water runoff and erosion, and improve air quality while reducing global warming. Studies from UW indicate interaction with wild green areas promote both mental and physical health.

So….back to our concerned dog walker and her fellow blackberry aficionados:

“Well,” we say, “We love blackberry pie too! However, we love this park more. Are you happy to have a wild urban forest in the neighborhood?” She nods and like everyone answers: “Yes.”

In the mid 2000s, one of our more observant neighbors realized that clematis, ivy, and blackberry had overwhelmed our neglected Greenbelt. The trees were covered with the vines and obviously struggling. Led by Libby Sinclair, the group “Save the Trees” was formed. A tiny dedicated band of neighbors worked rather casually and intermittently pulling out the ivy and clematis for a couple of years but this effort wasn’t enough.

We turned to Forterra, part of the Green Seattle Partnership, for the rescue! Green Seattle Partnership (GSP) was formed in 2004 as a collaborative effort of many entities: Among them: Seattle Parks, Dept. of Parks and Recreation, SPU and many, many non-profits. The GSP has 2,500 acres of green space under reforestation and has become the largest and most effective urban forest restoration project in America!

Forterra has many missions in the reforestation effort. One of their amazing contributions is encouragement and management of all the “civilian” volunteers out in the parks. Forterra supplies tools, mulching materials and expertise to assist volunteers care for their green spaces.

Ongoing classes and events for forest stewards ensure folks are developing the necessary skills. The untiring and dedicated staff led by Andrea Mojzak has truly been a lifesaver.

The final chapter will introduce us to the current reforestation efforts in the Greenbelt and our two forest stewards.
