Plants

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.

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.

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. 

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.

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. 

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.
