August 11, 2026 — Kelp forests in the United States are under threat and are facing the same stresses as the commercial fisheries that work around them. The Forest of the Sea by David Helvarg, published in May, tells the story of kelp, the importance of healthy kelp forests, and the challenges these habitats face. While this book is not about commercial fishing, it does include fishermen, and its insights are vital to those who make a living harvesting wild fish from a rapidly changing sea.

Kelp forests have evolved as the anchor habitat for nearshore ecosystems in the cold waters of temperate climes across the globe. Helvarg dives into the ecological and economic importance of kelp forests, and how they’re under threat as waters warm and other environmental stressors diminish their footprint, often drastically so.

As a commercial fisherman on the West Coast and as a journalist covering fisheries and oceans for more than 15 years, the health of fisheries and the health of kelp forests have mirrored each other from my vantage point. Since the Blob, the extreme marine heatwave that hit the West Coast from 2014-2016, whale entanglements ravaged the California Dungeness crab fishery while 90 percent of the Northern California kelp forests disappeared. This isn’t a situation where one affects the other, but parallel plot lines in the same story.

Helvarg, a veteran journalist who also serves as the executive director of Blue Frontier, an ocean advocacy NGO, uses Fort Bragg, Calif., as an example of just this. The shoreline of the small city nearly 200 miles north of San Francisco has historically been dominated by thick kelp forests teeming with life. It has also been an important commercial fishing port for Dungeness crab, salmon, and groundfish.
