In 1994 the City of Seattle and the Parks Department began to notice something wrong with trees in city parks. Research found that Seattle’s 2,500 acres of forested city parks were at risk from invasive plants such as English Ivy, Himalayan blackberry and bindweed. In 2004, experts projected that within 20 years about 70 percent of Seattle’s forested parkland trees would be dead. Previously, park-goers removed invasive species on their own, while non-profit and government organizations likewise worked independently. Rather than helping the problem, however, these piecemeal efforts placed an undue strain on the city’s existing resources. In order to save the parks, a shared effort between community members, experts in forestry, and the departments that held park resources was necessary. In 2004, the Green Seattle Partnership was formed, with the aim of arming citizens to help the city’s trees in partnership with the Department of Parks, Public Utilities and the Office of Sustainability and Environment. Under the leadership of Mark Mead, Senior Urban Forester, the Partnership created a 20-year strategic plan to sustain Seattle’s forested parks. Green Seattle Partnership is now the largest urban forest restoration project in the country. Mark’s use of agents across all sectors connected to the issue, and mobilizing community members to volunteer 500,000 hours by 2013 to the reforestation program, have put the Green Seattle Partnership in place to achieve their goal of planting 500,000 new trees by 2025.
