The voice of eelgrass
Wade out into the shallows of Puget Sound on a warm, sunny day and put your ear close to the water. You might catch the faint, champagne-like bubbling of eelgrass.
Indigenous Plants Forum raises awareness of native botanical treasures
A Lopez Island-based nonprofit says the protection of critical habitat for native plants can also preserve a wealth of traditional knowledge. The group is working with private landowners to raise awareness of culturally important plants hidden in the bogs and underbrush of Puget Sound's natural areas.
Science in the spotlight: Eelgrass recovery
The Washington Department of Natural Resources is studying new ways of increasing ecologically important eelgrass habitat in Puget Sound. It is part of the state's effort to boost eelgrass 20% Sound-wide by 2020. So far, recovery of the species has fallen short of that goal, but transplanting efforts are showing promise.
Studies show challenges for eelgrass restoration
As critically important eelgrass declines in some parts of Puget Sound, scientists are trying to plant more of it. The health of the ecosystem may be riding on their efforts, but what they are finding is something that farmers have known for thousands of years: Getting something to grow may be harder than you think.
Eelgrass restoration in Puget Sound: development of a site suitability assessment process
The restoration of eelgrass (Zostera marina L.) is a high priority for Puget Sound ecosystem recovery. In 2011, the State of Washington set a restoration target to increase eelgrass abundance by 20% in Puget Sound by 2020. Locating areas to restore eelgrass effectively and efficiently has been challenging for researchers. A 2018 article in the journal Restoration Ecology reports on efforts to identify potential restoration sites using simulation modeling, a geodatabase for spatial screening, and test planting.
Diving deeper to understand eelgrass wasting disease
New studies show that eelgrass wasting disease is more common in warmer waters, leading to concerns over the future effects of climate change on eelgrass populations in Puget Sound. We continue our series on science findings from the 2018 Salish Sea Ecosystem Conference.
2017 Addendum — Ocean Acidification: From Knowledge to Action
The Washington Marine Resources Advisory Council has released an addendum to the 2012 report Ocean Acidification: From Knowledge to Action. The original report established a statewide strategy for addressing ocean acidification in Washington. The addendum identifies updates based on emerging science and management practices and is intended to be a companion to the 2012 report.

Climate change vulnerability and adaptation in the North Cascades Region, Washington
A 2014 report by the North Cascadia Adaptation Partnership identifies climate change issues relevant to resource management in the North Cascades, and recommends solutions that will facilitate the transition of the diverse ecosystems of this region into a warmer climate.
Ecological effect of a nonnative seagrass spreading in the Northeast Pacific: A review of Zostera japonica
A 2014 literature review in the journal Ocean & Coastal Management suggests negative effects of nonnative eelgrass on the native species.
Shedding new light on eelgrass recovery
Scientists say eelgrass, an unassuming flowering plant found just off shore in Puget Sound, is vital to the health of the ecosystem. They also say the plant is declining. New and increasingly urgent efforts to restore it brought a group of researchers to the 2014 Salish Sea Ecosystem Conference.
Nitrogen as an Eelgrass Stressor in Puget Sound
Although overall eelgrass abundance appears to be stable in Puget Sound, some local areas are showing declines. A 2014 report from the Washington State Department of Natural Resources looks at the potential impact of increased nitrogen on eelgrass health.
Host demography influences the prevalence and severity of eelgrass wasting disease
A paper in the February 2014 journal Diseases of Aquatic Organisms examines the effect of leaf age on wasting disease in eelgrass across sites in the San Juan Archipelago. Co-author: Encyclopedia of Puget Sound topic editor Joe Gaydos.
Eelgrass
Eelgrass (Zostera marina L.) is an aquatic flowering plant common in tidelands and shallow waters along much of Puget Sound’s shoreline. It is widely recognized for its important ecological functions, and provides habitat for many Puget Sound species such as herring, crab, shrimp, shellfish, waterfowl, and salmonids.

Relic gardens: camas in the San Juan Islands
A botanist believes Coast Salish tribes once favored small islands in the San Juan archipelago for growing camas, an important food staple. Her studies may also show the vulnerability of these relic gardens to climate change as sea levels rise.
Shoreline formation in Puget Sound
Puget Sound has over 4,000 km (2,500 miles) of shorelines, ranging from rocky sea cliffs to coastal bluffs and river deltas. The exchange of water, sediment, and nutrients between the land and sea is fundamental to the formation and maintenance of an array of critical habitat types.
Ecosystem services in Puget Sound
Ecosystem services are the “outputs” and experiences of ecosystems that benefit humans, and are generated by the structure and function of natural systems, often in combination with human activities. The Millennium Ecosystem Assessment, a global effort to catalog and assess ecosystem status and functions, offers a useful classification scheme.
Food Web
Puget Sound hosts more than 100 species of seabirds, 200 species of fish, 15 marine mammal species, hundreds of plant species, and thousands of invertebrate species. These species do not exist in isolation, but rather interact with each other in a variety of ways: they eat and are eaten by each other; they serve as vectors of disease or toxins; they are parasitic; and they compete with each other for food, habitat, and other resources.
Intentional and unintentional introduction of invasive and non-native species
Non-native species are those that do not naturally occur in an ecosystem. A non-native species is considered invasive when it is capable of aggressively establishing itself and causing environmental damage to an ecosystem. Plants, animals, and pathogens all can be invasive.
