GS Day Poster 2013 with Logos low res

You are cordially invited to join the 8th Annual Green Seattle Day - November 2nd from 10 am to 2 pm. Green Seattle Day is a meaningful way to connect with nature and create a healthy and vibrant community by planting native trees and shrubs in a park near you. This is the biggest annual celebration of Seattle’s forested parks, the committed neighbors who care for them, and the kick-off event for the 2013-2014 restoration planting season.  All tools and supplies are provided. We welcome you to roll up your sleeves and have fun in the forest.

The event takes place in 17 parks city-wide.  The Mayor is confirmed to kick off the day at the West Duwamish Greenbelt, this year’s central hub site hosted by Nature Consortium, Forterra and Seattle Parks.  Let us know if you would like to come to the hub site at West Duwamish Greenbelt or if you would like to join one of the other Parks listed below.

The Trees of Life

UFSP Earlier this week, the Seattle City Council passed the new Urban Forestry Stewardship Plan. The goal of the plan is "to increase the health of the urban forest and to meet Seattle's goal of 30% canopy tree coverage by 2037." SvR's Peg Staeheli served on the Urban Forestry Commission.

We thought this might be a good opportunity to clear out some of the recent articles we've come across relating to the urban nature. Enjoy!


Weekly Reading: Trees in the Urban Landscape

tree tags Exploring Portland during a weekend trip, we came across these tree "price tags" along the South Park Blocks near PSU. A phenomenal public outreach campaign, they also reminded us of the multiple benefits of the urban forest that continue to be uncovered by researchers.

For example, DesignBuild Source reminds us about the importance of software like i-Tree in quantifying the value of our urban forest canopy (and perhaps more importantly, provides the nifty graphic below). It also suggests that Portland may have been low-balling their trees' value.

ACTrees runs down the latest research about how the urban forest affects carbon storage and sequestration, which refines previous research papers. The research found:

Total tree carbon storage in U.S. urban areas (c. 2005) is estimated at 643 million tonnes ($50.5 billion value; 95% CI = 597 million and 690 million tonnes) and annual sequestration is estimated at 25.6 million tonnes ($2.0 billion value; 95% CI = 23.7 million to 27.4 million tonnes).

"Perhaps we should start thinking of trees as part of our public-health infrastructure," says this fascinating article from Scientific American about how the presence of trees in your neighborhood serves as a predictor of your public health. Studying an area of Michigan where there was a large die off of trees due to the emerald ash borer, the researchers found:

"According to their mathematical model, the presence of the borer, and the subsequent loss of trees, was associated with 6.8 additional deaths per year from respiratory causes and 16.7 additional deaths per year from cardiovascular causes per 100,000 adults. That's more than 21,000 deaths in total."

Fast Company brings us the story of South African photographer Dillon Marsh who studies the "peculiar nature" of cell phone towers dotting the urban landscape, disguised as trees. Some examples of his work is below but be sure to also check out his website.
