The Saliş Sea, also known as the Salish Sea, is a complex waterway system situated along the western coast of North America, primarily between the Canadian province of British Columbia and the U.S. state of Washington. It encompasses an intricate network of coastal inlets, straits, fjords, and islands, including popular destinations like Puget Sound, the Strait of Georgia, and the Strait of Juan de Fuca. The Salish Sea’s boundaries are not officially recognized by international bodies but are generally considered to include the waters from the northern end of the Strait of Juan de Fuca near Victoria, British Columbia, to the southern end of Puget Sound near Olympia, Washington, and extending northwestward into the Strait of Georgia up to Desolation Sound. This maritime region is renowned for its stunning natural beauty, diverse marine ecosystems, and rich cultural heritage, with Indigenous peoples such as the Coast Salish having inhabited its shores for thousands of years. The Salish Sea serves as a vital habitat for numerous species of marine life, including orcas, salmon, seals, and seabirds, making it a significant ecological hotspot and an essential area for conservation efforts. Additionally, the Salish Sea supports various economic activities such as fishing, shipping, tourism, and recreation, contributing significantly to the livelihoods and economies of the surrounding communities. Despite its ecological and cultural importance, the Salish Sea faces various environmental challenges, including pollution, habitat degradation, overfishing, and the impacts of climate change, prompting collaborative conservation initiatives between government agencies, Indigenous groups, environmental organizations, and local stakeholders to protect and sustainably manage this precious marine ecosystem for future generations.

The Salish Sea is a complex and ecologically rich marine environment that encompasses a diverse array of coastal ecosystems, including rocky shorelines, tidal flats, eelgrass beds, kelp forests, and deep submarine canyons. This maritime region experiences a temperate climate influenced by the Pacific Ocean, characterized by mild winters, cool summers, and abundant rainfall, which supports the growth of lush forests and sustains a diverse range of terrestrial and aquatic life.
One of the defining features of the Salish Sea is its intricate network of waterways, which includes several major bodies of water such as Puget Sound, the Strait of Juan de Fuca, and the Strait of Georgia, as well as numerous smaller bays, estuaries, and fjords. These interconnected channels provide critical habitat for a wide variety of marine species, including commercially important fish like salmon, herring, and halibut, as well as charismatic megafauna such as orcas (killer whales), seals, sea lions, and porpoises.
The Salish Sea region has been inhabited by Indigenous peoples for thousands of years, with various Coast Salish tribes, including the Lummi, Swinomish, Suquamish, and Tsleil-Waututh, among others, maintaining cultural connections to the land and sea. These Indigenous communities have traditionally relied on the marine resources of the Salish Sea for subsistence, sustenance, and cultural practices, including fishing, hunting, gathering, and ceremonial activities, and continue to assert their rights and stewardship responsibilities over these ancestral territories.
In addition to its ecological and cultural significance, the Salish Sea plays a vital role in the economic livelihoods of the surrounding region, supporting a wide range of industries and activities. Commercial and recreational fishing are major economic drivers, with the Salish Sea supporting lucrative fisheries for salmon, shellfish, crab, and other marine species. The region also serves as a critical transportation corridor for maritime commerce, with busy shipping lanes connecting ports in Canada and the United States and facilitating the movement of goods and commodities to international markets.
Tourism and recreation are also important aspects of the Salish Sea economy, attracting millions of visitors each year who come to enjoy activities such as whale watching, boating, kayaking, scuba diving, and beachcombing. Popular tourist destinations within the Salish Sea region include the San Juan Islands, Victoria, Vancouver, and the Olympic Peninsula, all of which offer stunning natural scenery, rich cultural heritage, and a wide range of outdoor recreational opportunities.
Despite its ecological and economic importance, the Salish Sea faces numerous environmental challenges and threats to its long-term health and sustainability. Pollution from urban runoff, industrial activities, agricultural runoff, and marine debris poses significant risks to water quality and ecosystem health, threatening the survival of marine species and compromising the safety of seafood resources. Habitat loss and degradation, primarily due to shoreline development, dredging, and land reclamation, have also taken a toll on sensitive coastal ecosystems, leading to declines in biodiversity and the loss of critical habitat for fish, birds, and other wildlife.
Climate change represents another major threat to the Salish Sea, with rising temperatures, ocean acidification, sea level rise, and changes in precipitation patterns all expected to have profound impacts on marine ecosystems and coastal communities. These climate-related impacts are likely to exacerbate existing environmental stressors and pose significant challenges for the management and conservation of the Salish Sea in the coming decades.
In response to these challenges, governments, Indigenous nations, non-profit organizations, and other stakeholders have implemented various conservation and management initiatives aimed at protecting and restoring the health of the Salish Sea. These efforts include habitat restoration projects, pollution prevention measures, marine protected areas, sustainable fisheries management, and climate adaptation strategies, all of which seek to safeguard the ecological integrity and cultural heritage of this unique marine environment for future generations. By working together collaboratively and engaging in science-based decision-making, stakeholders hope to ensure the long-term resilience and vitality of the Salish Sea for the benefit of both people and nature.
