- Distribution and potential effects of a non-native seagrass in Washington State — Zostera japonica Workshop — September 23-24, 2010 (report)
Zostera japonica is an intertidal plant also called Asian, dwarf, Japanese or narrow-bladed eelgrass, duck grass and, sometimes, simply eelgrass. The first Z. japonica specimen was collected in Willapa Bay, Wasington, on Sept. 9, 1957. Over time, it became clear that this species was growing in the soft-bottom intertidal regions of coastal esturaries, small bays and fringing coastlines from Southern British Columbia to Southern Oregon. It is now also found in Northern California, and the size of several of the more northerly populations has increased.
A two-day workshop at the University of Washington’s Friday Harbor Labs assembled regional experts for discussion of the state of science of Z. japonica. Workshop objectives and session titles are included below. A white paper summarizing the state of science discussions and research priorities is available on this page under Workshop Report (above).
- To provide a forum for the exchange of information about Z. japonica.
- To identify what is known about North American Z. japonica populations.
- To recommend priorities for future research.
- To produce a white paper based on workshop discussion.
- To disseminate workshop information via Web sites hosted by the Friday Harbor Laboratories and/or Washington Sea Grant, University of Washington.
- Potential Impact of Z. japonica Invasion on Ecosystem Structure and Function
- Community and Species-Level Interactions Involving Z. japonica
- Monitoring Z. japonica Distribution and Expansion
- Influence of Predicted Climate Change Elements on Z. japonica Distribution
- Genetic Variation within and among Z. japonica Populations
