Seattle’s massive timber are disappearing on the very second we’d like them most. As our local weather warms and growth accelerates, town should do extra to guard mature timber which can be important to public well being, local weather resilience and biodiversity. I urge the brand new mayor and Metropolis Council to take motion to guard our timber — an effort that almost all Seattleites assist.
I dwell in Ravenna, the place 4 of the biggest conifer timber in a two-square-block space have been lower down prior to now 5 years. Sadly, this displays a citywide sample of incremental lack of mature native timber on personal property.
Between 2016 and 2021, town of Seattle misplaced 255 acres — 1.7% — of its tree cover, an space equal in dimension to Inexperienced Lake. Some losses are incremental, like these talked about above, whereas others consequence from massive growth initiatives that clear complete plenty of timber.
Most tree removals are motivated by official security considerations. Nonetheless, at the very least one of many 4 misplaced timber referenced above posed no hazard in any way and was eliminated just because the landowner “didn’t just like the seems of it.” This highlights a crucial coverage hole: Seattle permits the lack of irreplaceable ecological belongings with minimal evaluate and weak enforcement.
When massive timber are eliminated, mitigation necessities are inadequate. Planting small saplings doesn’t compensate for the lack of 60- to 100-foot conifers that present many years of amassed ecological companies, together with carbon sequestration, stormwater administration, air filtration, shade and wildlife habitat.
Seattle’s personal Urban Forestry Plan makes this clear. It emphasizes that preserving present timber is way more practical than changing them, as a result of it takes many years for timber to achieve maturity. The plan additionally prioritizes evergreen timber, which give year-round cover, soak up extra carbon dioxide, cut back air air pollution and mitigate stormwater in the course of the wet season.
Regardless of this steerage, Seattle continues to lose tree cover. Town’s aim of 30% cover protection is modest, but we’re backsliding. In accordance with Birds Join Seattle, cover cowl declined from 28.6% in 2016 to twenty-eight.1% in 2021.
The stakes are excessive. Through the June 2021 warmth wave, temperatures reached 108 levels, contributing to lots of of deaths throughout the Pacific Northwest. Timber are among the many simplest instruments we’ve got to cut back city warmth, defend weak populations and construct local weather resilience. Local weather Central studies that Seattle ranks among the many prime 5 U.S. cities for elevated warmth threat — an alarming distinction for a metropolis that prides itself on environmental management.
Timber and growth can and should coexist. Different cities — together with Atlanta, Ga.; Charleston, W.V.; Charlotte, N.C.; Little Rock, Ark.; and Tampa and Tallahassee, Fla. — have increased tree cover protection than Seattle. Portland, the unique “Stumptown,” has a aim of 33%. Charlotte’s aim is 50%. It is a matter of coverage selection, not inevitability.
I urge Mayor Katie Wilson and the Metropolis Council to considerably bolster protections for mature timber, particularly evergreens; enhance significant mitigation necessities; and create stronger incentives to protect timber on personal property. If Seattle is to stay livable, equitable and climate-resilient, we should begin treating it that manner. Enhancing our weak Tree Ordinance is an effective place to start out.
