Leading experts from academia, agencies, industry,
and conservation groups met recently in Shelton, Washington for the
second West Coast Native Oyster Restoration workshop. Sixty
attendees listened to presentations and used the workshop as a forum
to discuss the science, policy, and practice of the growing efforts
to restore the Olympia oyster (Ostrea conchaphila/Ostrea
lurida), the West Coast’s only native oyster. Presentations
addressed genetic variation and taxonomy, larval recruitment,
habitat preferences, historic distribution, community participation
in restoration, and many other topics. The workshop also featured
a demonstration on making concrete-coated spat collectors out
of biodegradable materials. Squaxin Island
Tribe member Rick Peters kicked off the workshop with a tribal
blessing, followed by the keynote address by Dr. Jeff Koenings,
Director of the Washington Department of Fish and Wildlife. A
pre-conference field trip took participants to a self-sustaining bed
of native Olympia oysters (estimated to contain millions of
oysters), and then to a restoration project funded by the NOAA
Restoration Center. The restoration project is a collaboration
between The Nature Conservancy, Puget Sound Restoration Fund, the
private tideland owners, U.S. Department of Agriculture, Taylor
Shellfish Farms, Washington Department of Natural Resources, and
Thurston County Parks Department. A seafood dinner sponsored by
Taylor Shellfish exemplified the solid relationships between
government, NGOs, and the commercial shellfish industry in the area
of habitat restoration. Workshop sponsors included NOAA, Puget Sound
Restoration Fund, UC Davis and Taylor Shellfish Farms. Proceedings
from the first workshop are available on the NOAA
website and a special issue of the Journal of Shellfish Research
is in preparation with papers reflecting the 2006 meeting
topics.

A volunteer-based effort was used to restore
oyster reefs in the Canaveral National Seashore, within
Florida's Indian River Lagoon. Phase I efforts demonstrated
the utility of using 'oyster mats' to stabilize the outer
margins of oyster reefs against boat wakes, as well as the
strong public support for this restoration effort. © Anne
Birch and Linda Walters, 2007. |
Phase I of a restoration project designed to
restore oysters to Indian River Lagoon in Florida has just been
completed. Anne Birch, Indian River Lagoon Program
Director for The Nature Conservancy (TNC) collaborated with Dr.
Linda Walters from the University of Central Florida (UCF) to deploy
thousands of ‘oyster mats’ to help restore oyster reefs within the
Canaveral National Seashore (CANA). Oyster reefs
throughout the lagoon have been affected by various factors, but
boat wakes in particular have caused problems in recent decades
within the Mosquito Lagoon basin. The oyster mats were
designed by Walters and students in her laboratory and early pilot
studies in the field suggested that they were a viable way to
stabilize the margins of reefs that were being affected by boat
wakes. With this project, they have shown that the mats
are effective at stabilizing the edges of reefs provide a perfect
substrate for young oysters to re-colonize the reefs and help
support a diverse assemblage of other species.
As with most restoration projects, there were
surprises and unexpected outcomes along the way. In a recent
St. Johns River Water Management District newsletter, Anne notes
that the project provided a tangible connection between people and
the lagoon – a connection so powerful that they found themselves
“awash with volunteers”. While the TNC-UCF team originally
expected to recruit perhaps 300 people to lend their time to the
project, ultimately they worked with more than 5,200 people over a
two year period. These volunteers proved invaluable, however,
and enabled the construction and deployment of 3,556 shell mats with
some 128,000 shells attached by cable ties to provide a stable place
for young oysters to attach. Another unexpected facet to the
project was the involvement of Royal Caribbean Cruise Line’s
“Mariner of the Seas” ship and its crew. The ship and its crew
helped with the project by taking aboard the thousands of shells
needed for the mats and using the equipment in the ship’s
maintenance shop to drill a hole in each shell so that it could be
attached to the mat once back ashore. In doing so, the “Mariner of
the Seas” enabled the project team and its volunteers to create
enough mats to deploy throughout this spring and summer. Underpinning this restoration work is science, and
the project provided a valuable platform for research that is
already shaping future restoration efforts. Andrea Barber, a
graduate student in Dr. Walter’s lab, completed her master’s thesis
using data from the project and was able to demonstrate the areas
restored with reef mats support a diverse array of marine life in
the Lagoon. The project is entering Phase II, with additional reef
margins targeted for restoration in 2007 – 2009. Monitoring of
the Phase I reef will continue, along with assessment of areas
restored in Phase II. For additional information about
the project, contact Anne Birch

Restore
America’s Estuaries is pleased to announce the Call for
Dedicated Sessions, Presentations and Posters for the 4th
National Conference on Coastal and Estuarine Habitat Restoration –
Creating Solutions through Collaborative Partnerships.
Proposals are due January 31, 2008. To download
the Call for Dedicated Sessions, Presentations and Posters, visit www.estuaries.org/conference.
Restore America's Estuaries' 4th National
Conference on Coastal and Estuarine Habitat Restoration is the only
national conference focused on the goals and practices of coastal
and estuarine habitat restoration. The five-day Conference will
explore the state-of-the-art in all aspects and scales of
restoration, and will be comprised of field sessions, plenary
sessions, expert presentations, special evening events, workshops, a
poster hall, and a Restoration Exposition.
The 4th National
Conference will be held in New England, October 11-15, 2008 at the
Rhode Island Convention Center in Providence. Renowned for its
natural beauty, history, and cultural offerings, the autumn colors
of New England will set the background for this premier event. The
Conference goals are to advance the science, pace, practice, and
success of habitat restoration at all scales by bringing together a
broad spectrum of people who work in policy, science and strategy,
business and best practices.
For more information, contact
Steve Emmett-Mattox at 303-652-0392 or program@estuaries.org.
