Yes, you read that right. Instead of having more protection, trees in Environmentally Critical Areas have even less protection than all other trees. Trees in ECAs are an essential bulwark against climate change impacts — help us raise awareness and change Seattle's code.

Seattle just released new zoning codes for former single-family neighborhoods. Instead of following the science – which shows that trees and green space build climate resilience and save lives – Seattle is going in the opposite direction and drastically reducing tree canopy.

Towering evergreen trees sheltering homes define Seattle. They mean we can survive and even thrive in the face of growing climate impacts. But our roadmap to natural sustainability is under attack by developer interests who gain quick profits from “lot sprawl.”

We get a lot of questions from our elected officials and builders about if building housing and trees is possible — and if so, how we can do it.‍ Here's Tree Action Seattle's expert-backed* guide to how we can build up and green Seattle.

The Omnibus bill, aka CB 120823, is a bill to make small, technical and grammatical changes to Seattle’s building and tree code, and is up for a public hearing next Wednesday.‍ The bill leaves the most damaging legislative pieces of Seattle’s tree ordinance intact.

In the six months leading up to when Seattle’s new tree ordinance took effect, Seattle's developer lobby met with the city over 100 times.

Our analysis of tree removal data from the City of Seattle shows over 1,000 trees have been removed in 2024 alone.

SDCI wants us to believe hundreds of trees are saved from removal on development projects, but their own data reveals that almost none are truly protected.

Use this guide to see if a tree is under threat of illegal removal and what to do next.

A new report by Birds Connect Seattle exposes that Seattle's latest tree law will result in the loss of over 200 acres of trees in Environmental Justice Priority Areas (EJPAs).

Tree Action Seattle's investigation into a recent surge in tree removals has revealed SDCI's careless management of our urban forest.
