Kelp forests are some of the most productive and dynamic ecosystems in the ocean. These underwater forests, composed of large brown algae, play a vital role in marine environments.

Join us on a deep dive into what kelp is, its importance, the threats it faces, and what we can do to protect it.

‍

What is Kelp?

Kelp refers to large brown algae found in coastal waters. There are several species of kelp, with giant kelp being one of the most well-known.

Kelp grows in dense forests in nutrient-rich waters, anchored by holdfasts. It can grow up to 2 feet per day under ideal conditions, forming towering underwater canopies.

Why is Kelp Important?

Biodiversity Hotspots: Kelp forests provide habitat and food for a wide range of marine species, including fish, invertebrates, and marine mammals. They are vital for maintaining marine biodiversity.

Healthier and more diverse ecosystems are generally more effective at sequestering carbon and maintaining stable food webs.

‍

Carbon Sequestration: Kelp forests are highly effective at capturing and storing carbon dioxide (CO2) from the atmosphere. Kelp, like other photosynthetic organisms, absorbs CO2 during photosynthesis and converts it into biomass.

Unlike terrestrial plants, much of the carbon in kelp is quickly transferred to the ocean floor when the kelp dies and sinks, effectively sequestering the carbon for potentially thousands of years. This process is often referred to as "blue carbon" sequestration.

Globally, seaweeds (including kelp) are thought to sequester nearly 200 million tonnes of carbon dioxide every year – as much as New York State’s annual emissions.

‍

Coastal Protection: Kelp forests act as natural barriers, reducing wave energy and protecting coastlines from erosion.

Kelp forests can also help cool coastal waters, which is beneficial in the context of rising global temperatures. The dense canopies of kelp forests shade the waters below, which can help regulate local water temperatures. This cooling effect can be crucial for species that are sensitive to temperature changes, helping to maintain local biodiversity.

Threats to Kelp Forests

Climate Change: Rising sea temperatures and ocean acidification are major threats to kelp forests. These changes can lead to reduced growth rates and increased susceptibility to diseases.

Overfishing: The removal of key species, such as sea otters, disrupts the balance of kelp ecosystems, leading to overgrazing by herbivores like sea urchins.

Pollution: Nutrient runoff from agriculture and coastal development can lead to algal blooms, which block sunlight and smother kelp beds.

‍

What We Can Do to Help Kelp?

Restoration Efforts: Restoration projects aim to replant and protect kelp forests, often involving the removal of invasive species and reintroduction of keystone predators like sea otters.

Sustainable Practices: Supporting sustainable fisheries and reducing pollution can help protect kelp forests. Reducing carbon emissions is also crucial to mitigating climate change impacts.

Education and Awareness: Raising awareness about the importance of kelp forests can lead to greater public support for conservation efforts.

Out of Sight, Not Out of Mind

Kelp forests are not only vital for marine life but also for the health of our planet. They provide critical underwater ecosystem services that support biodiversity, protect coastlines, and help combat climate change.

With Ecodrive, you can contribute to kelp reforestation efforts in Canada.

Ecodrive is dedicated to cultivating 5,000 meters of kelp seeded lines each year (500,000 spores) within a licensed aquaculture area in Moon Bay, Nelson Island.

The cultivated kelp lines will serve as crucial habitats for herring and salmonids that traverse the Agamemnon Channel (Sunshine Coast, BC Canada) within the shíshálh people''s territory.
