Help us build forests

Help us continue to build forests We continue to do our part in King County's effort to plant 1 Million Trees by 2020 to reduce carbon pollution and prepare for impacts of climate change, one of the actions outlined in the 2015 Strategic Climate Action Plan.

Help us reach this goal while also restoring habitat for fish and wildlife and enhancing recreation opportunities for all of us.
