Ancient and carbon-rich, old-growth forests play an irreplaceable role in the environment. Their complex ecosystems clean the air, purify the water, cool the planet, and teem with life. In a time of climate catastrophe, old-growth and other natural forests face existential threats caused by humans―and their survival is crucial to ours.

In a bicoastal journey, environmental journalist Lynda V. Mapes connects the present and future of Pacific Northwest forests to the legacy forests of the northeastern United States. Beginning in Oregon and Washington, where old growth supports, and is supported by, the region’s salmon, we meet Jerry Franklin, who led scientists in recognizing and studying the distinctiveness of these majestic spaces. From there, we journey to Vancouver Island, where Indigenous activists and scientists strive to preserve the health of Nuu-chah-nulth traditional homelands amid continued clearcutting. On the East Coast, we see the corduroy patterns of lands that have been logged for generations, leaving industrial carnage along formerly life-filled waterways.

Mapes invites us to understand the world where trees are kin, not commodities. The Trees Are Speaking is a must-listen for those with a deep interest in environmental stewardship, Indigenous land rights, and the urgent challenges posed by climate change.
