Joining the conversation are Aaron Slade, a marine ecologist passionate about coastal restoration; Nicole Smith, an archaeologist who has dedicated over two decades to understanding shoreline ecosystems; Marco Hatch, an environmental science professor and member of the Samish Indian Nation; and Nicole Norris from the Chalalt First Nation. They delve into the fascinating world of sea gardens, exploring their role in food security and biodiversity. The guests highlight the importance of Indigenous knowledge in environmental stewardship and the urgent need to revive these gardens amidst climate change challenges.
Sea gardens, or clam gardens, enhance food security and biodiversity by creating optimal intertidal conditions for clam cultivation and other marine species.
The integration of traditional ecological knowledge with contemporary science fosters effective restoration efforts and empowers Indigenous communities in resource management.
Reviving ancient clam gardening practices addresses food insecurity and connects communities to their cultural heritage in the face of climate change.

The Importance of Sea Gardens
Sea gardens, which once were known as clam gardens, are intricate intertidal ecosystems created by Indigenous peoples to enhance food security and biodiversity. These structures involve moving rocks to flatten the beach, thus creating optimal conditions for clams to thrive within a narrow tidal zone. The cultivation of these gardens dates back approximately 4,000 years and emphasizes the deep-rooted connection between Indigenous practices and environmental stewardship. By creating and maintaining these ecosystems, communities not only secure their food sources but also promote the health of diverse marine species, highlighting the necessity of human intervention in ecological systems.
Ecological Benefits and Biodiversity
The complex ecosystems supported by sea gardens yield significant ecological benefits, fostering a variety of marine life beyond just clams. Species such as sea cucumbers, red rock crabs, sea stars, and various types of snails thrive in these habitats, showcasing the biodiversity that results from intentional ecological management. Marine ecologists have found that clam gardens can yield two to four times more clam biomass than unmanaged areas, indicating their effectiveness in promoting healthy marine populations. Traditional ecological knowledge, passed down through generations, has been pivotal in understanding how to enhance habitats suited to sustain these diverse species.
Impact of Climate Change on Sea Gardens
As climate change continues to affect sea levels and marine ecosystems, the adaptability of sea gardens becomes increasingly significant in ensuring food security for Indigenous communities. Historical practices of modifying beaches through clam gardening reflect a deep understanding of local ecological changes, allowing communities to manage their resources sustainably. The presence of clam gardens, previously believed to be secluded in history, can serve as a blueprint for contemporary climate adaptation strategies in the face of rising sea levels. By revitalizing these ancient technologies, there is potential for enhancing resilience against climate impacts while reconnecting communities with their cultural heritage.
Integrating Traditional Knowledge with Modern Science
The collaborative efforts between Indigenous communities and Western scientific institutions exemplify the potential of combining traditional ecological knowledge with contemporary environmental science. Initiatives like the Sea Gardens Project illustrate how such partnerships can lead to effective restoration efforts while respecting cultural practices and knowledge. The integration of these two approaches not only enriches ecological understanding but also empowers Indigenous voices in managing traditional resources. This braiding of knowledge systems is essential for crafting sustainable practices that honor both historical insights and present-day scientific research.
Revitalizing Food Security through Sea Gardens
The revival of sea gardens is closely linked to addressing the pressing issues of food insecurity experienced by many Indigenous communities today. By reactivating traditional clam gardening practices, communities are working to ensure sustainable food sources that are less reliant on external supplies, particularly in light of recent supply chain disruptions. Efforts to educate communities about the safety and health benefits of consuming locally harvested clams are crucial, as are initiatives that promote responsible harvesting practices. Ultimately, fostering a sense of connection to these environments helps cultivate resilience, self-sufficiency, and a renewed appreciation for ancestral practices.
Food security, climate adaptation, and vibrant biodiversity all in one place — welcome to the ancient and diverse technologies of Sea Gardening.
These widespread (but often overlooked) monumental rock features are proof positive of thriving Indigenous maricultural systems all around the Pacific Rim, since time immemorial. These spaces are not only simply stunningly beautiful spots to hang out, they're also a powerful symbol of ecocultural restoration; of Indigenous sovereignty, self-determination, and internationalism; of relationship building; and of the kind of future that is possible as we adapt to a changing climate and rising sea levels. We hope you find them as inspiring as we do.
Join us as we visit a sea garden, learn about how they work, and meet a few of the people bringing them back to life.
