Edible Camas Meadows of the Pacific Northwest


Traditional ecological knowledge (TEK) is a valuable resource that has been passed down through generations by many cultures and communities. It encompasses the accumulated understanding of the natural world that has been acquired over time through observation, experimentation, and cultural transmission. In this blog post, we will delve into the specific example of the Salish people's use of TEK to create and manage sustainable and edible ecosystems, such as the edible camas meadows.

The Salish people, who are indigenous to the Pacific Northwest region of North America, have a long history of utilising TEK to create and manage camas meadows. Camas (Camassia quamash) is a perennial wildflower found in the Garry oaks ecosystem and produces edible bulbs which has been a staple food source for the Salish people for thousands of years. It provides a sweet, starchy staple that is high in fiber and nutrients, and can be preserved and consumed in a variety of ways. This allows for year-round sustenance, long-distance travel, trade opportunities, and sophisticated cultural traditions. The Salish people have traditionally used a combination of fire management and low-impact hunting practices to create and maintain camas meadows.

The use of fire management in the creation and maintenance of camas meadows is a key component of the Salish TEK. The Salish people use fire to clear out underbrush and control invasive plant species, which helped to create optimal growing conditions for the camas. Furthermore, the use of fire helped manage soil fertility by releasing nutrients from the organic matter, and promoting seed germination. The selective use of fire in this way helped to create a mosaic of plant communities that were conducive to the growth of camas.


In addition to fire management, the Salish people used low-impact hunting practices, such as selective hunting of deer, to control the population of herbivores that could overgraze the camas meadows. This approach helped to maintain a balance between the camas and the herbivores, ensuring that the camas meadows remained productive.


The Salish are a highly sophisticated society deeply connected to the sea, forest and meadow ecosystems that they inhabit. They believe that the health of the camas meadows was directly linked to the health of the surrounding ecosystems. Among the keystone species that sustain them are Pacific salmon, Western red cedar, and camas. These resources, along with many others, were part of a large network of sustainable agroecosystems, which are land management systems that support the human inhabitants whilst increasing biodiversity. Instead of attempting to control natural processes, these systems rely on stewardship and low-scale intervention to encourage resources in the places where they thrive. This allows for a symbiotic relationship between the population and the land, as people move between sites seasonally for maintenance and harvesting.

The TEK of the Salish people regarding the creation and management of camas meadows is a valuable resource that offers insights into the development of sustainable land management strategies. The use of fire management, low-impact hunting, and emphasis on biodiversity, has allowed the Salish people to create a sustainable and productive ecosystem that provides a reliable food source for their communities.


For my research in designed edible meadows, I am particularly interested in the unique agroecosystems represented by camas meadows and the role of the Camas in Salish culture. It is important to recognize and acknowledge the contributions of indigenous cultures and their traditional ecological knowledge. By incorporating traditional knowledge and practices into modern land management strategies, I believe it can help us move towards a truly regenerative culture that supports food security, biodiversity, and ecosystem resilience. Allowing humans to inhabit ecosystems in symbiosis with other life.
