Environmental issues in Puget Sound

Puget Sound is a deep inlet of the Pacific Ocean in Washington, extending south from the Strait of Juan de Fuca through Admiralty Inlet. It was explored and named by Captain George Vancouver for his aide, Peter Puget, in 1792.

The ninth Puget Sound Update, from the Puget Sound Action Team reports that:^[1]

"the Puget Sound has biological resources which include all of the living organisms which inhabit the marine waters and shorelines. These biological resources are plankton, invertebrates, fish, birds, mammals, and aquatic vegetation, including species that are either residential or migratory."

The abundance of creatures and foliage allowed for the native peoples of the area to thrive and prosper by harvesting it. Many of the problems of the Puget Sound originated from explorers and trappers hunting and killing the indigenous species off of which the natives thrived and prospered.^[2] In the past 30 years there has been a large recession in the populations of the species which inhabit the Puget Sound. The decrease has been seen in the populations of: forage fish, salmonids, bottom fish, marine birds, harbor porpoise and orcas. This decline is attributed to environmental issues in Puget Sound. Because of this population decline, there have been changes to the fishery practices, and an increase in petitioning to add species to the Endangered Species Act (ESA). There has also been an increase in recovery and management plans for many different area species.^[1]

The cause of these environmental issues are, toxic contamination, eutrophication (low oxygen due to excess nutrients), and near shore habitat changes.^[1] The Puget Sound has been affected by urbanization and the toxic pollutants it produces. As a government document regarding this issue says, "A major contributor of these toxic pollutants entering the Sound is the stormwater that runs off our highways, roads, driveways, roofs, parking lots, disturbed soils, and other developed surfaces." They also talk about the loss of habitat. In the last 125 years, the Puget Sound has lost or damaged 70 percent of their habitats including the salt marshes, eelgrass beds and the estuaries.^[3]
