Ten Things You Didn’t Know About Kelp

Cover image: Taylor Griffith
Kelp forests are some of the most dynamic and productive ecosystems on the planet, but many people don’t dip below the canopy to find out just how incredible they really are. From record-breaking growth rates to surprising uses spanning food, art, and innovation, here are ten things about kelp you might not know, as well as what you can do to help the kelp! 
1. Kelp forests are the largest marine habitat on Earth
Kelp forests cover more than one-third of the world’s coastlines, stretching across the shorelines of 21 countries on each continent except Antarctica. From the fjords of Norway to the rocky shores of New Zealand, these underwater forests thrive in cold, nutrient-rich waters where they form the foundation of nearshore marine ecosystems.…

5 Hope Spots You Might Not Know Have Kelp Forests

Cover image: Taylor Griffith
Kelp forests thrive in some surprising places around the world. From the icy waters of Iceland to the tropical seas of the Galápagos Islands, these underwater forests create vibrant habitats that support diverse marine life and sustain coastal communities. Across the globe, 32 Mission Blue Hope Spots are known for their vital kelp ecosystems, and here we take a closer look at five of these kelp Hope Spots and the unique stories they tell.
Northeast Iceland Hope Spot

At the edge of the Arctic Circle, the Northeast Iceland Hope Spot is a haven of geothermal vents, rocky coastlines, and cold, clear waters where underwater forests of tangle kelp (Laminaria hyperborea) thrive. These undersea habitats are part of an ecosystem that supports puffins, Arctic terns, and whales, and some of Europe’s most important bird colonies.…

The Mission Blue Kelp Initiative: A Hope Spot Partnership for Kelp Protection

The Mission Blue Kelp Initiative is a partnership with The Plum Foundation to support the conservation and protection of kelp forests in Hope Spots around the world. Given the ecological significance of kelp forests, this partnership prioritizes the protection of healthy kelp ecosystems where possible, the recovery of degraded areas by mitigating stressors, and when necessary, active restoration methods. 
We believe protection to be the most effective strategy, but in the face of warming ocean temperatures due to global climate change, other approaches are also required. The Hope Spot network includes over 30 Hope Spots with kelp forests in their waters, and in 2025, we are supporting active conservation, research, and restoration efforts with researchers in four key areas around the globe.…

Over 700 delegates from around the world gathered in the beautiful city of Victoria on Vancouver Island last week for the 25th International Seaweed Symposium. This week-long event convened global experts in all the arenas of algae, with sessions and special workshops focused on conservation, restoration, cultivation, policy, and global strategy for seaweed and kelp.
I was honored to attend the conference in my capacity as Mission Blue’s Kelp Initiative Program Manager and found myself among a slew of fellow kelp enthusiasts! I’ve been diving in kelp forests and studying the ecology of these magnificent systems for over a decade at this point, from my vantage point in the giant kelp forests of San Diego, California, and am always amazed at how much more there is to learn. …

Kelp 101: What Are Kelp Forests, and Why Do They Matter?

Kelp forests, to those who know and love them, are some of the most majestic places on Earth. But for many others, these magnificent ecosystems remain unknown, out of sight and out of mind beneath the waves. 
Found along 30% of the world’s coastlines in temperate waters, these underwater forests provide critical habitat, biodiversity, and benefits to thousands of marine species, coastal communities and the planet as a whole. 
Despite their importance, kelp forests are often overlooked in high-level conservation by better-known systems like coral reefs or mangroves. But a growing global movement, energized by the global community of kelp lovers and organizations like the Kelp Forest Alliance (KFA) are working to change that, and to help the kelp.…

Pacific North West Protectors: Guardians of the Kelp

Written by Madison Churchill; photos by Hannah Gabrielson

Donned in thick neoprene and extra-long fins, we dive below the surface. One breath at a time takes us deeper into an underwater world, bringing everything into focus with each descent. We are freediving at Lime Kiln State Park on San Juan Island, a historically thriving kelp forest that’s now under threat. What we see now is alarming. One dip beneath the surface reveals a barren of sea urchins as far as the eye can see. These spiny invertebrates serve their function in small numbers, but when left unchecked, can devour kelp like no other. Some stalks of kelp have been spared and continue to grow, but there’s been a clear shift. Something is out of balance.…
