Crab Bank

Seabird Sanctuary

PROJECT UPDATE

The initiative to save Crab Bank Seabird Sanctuary has taken a giant step forward with the U.S. Army Corps of Engineers’ recent approval of the $124 million Lower Harbor contract as part of the Charleston Harbor Post 45 Deepening project. 

  

Awarded in August to Virginia-based Norfolk Dredging Company, the Lower Harbor dredging contract includes an option that will allow the placement of approximately 660,000 cubic yards of sediment within the historic footprint of Crab Bank — material that would otherwise be disposed of in an EPA-approved disposal area offshore. The local share of the final cost to place the dredge material on Crab Bank will be only $132,000 — considerably less than the Corp’s original estimate. 

“This is great news for everyone that stepped up to the plate to protect Crab Bank,” said SCDNR Director Robert Boyles. “This means that we will be able to continue efforts with our partners to better understand, protect, and improve coastal bird habitat up and down the South Carolina coastline.” 

  

The Corps expects to supply the remaining $245,000 needed for the project. When completed, the work will restore approximately 28 acres of prime nesting habitat above the high tide line for coastal birds. Recognizing the need for a strategy to identify funding for Crab Bank, SCDNR worked with Audubon South Carolina, the South Carolina Coastal Conservation League and the Coastal Expeditions Foundation to make the success of Crab Bank a reality by establishing the South Carolina Coastal Bird Conservation Program, an SCDNR-managed fund that can receive donations, draw interest and help finance critical projects to help protect coastal birds. 

“The beauty of the story of Crab Bank is, not only did it provide an opportunity for collaboration among interested conservation-minded folks to save the island, it also spearheaded the development of SCDNR’s Coastal Bird Conservation Program, an even bigger platform that we’ll have going forward to protect and perpetuate the conservation of all sorts of coastal birds— from shorebirds and seabirds to marshbirds and wading birds,” said SCDNR Office of Environmental Programs Director Lorianne Riggin. “Going into this massive fundraising effort, no one knew that we would come out on the other side of it having met the dollar mark AND with the opportunity to do even more for coastal birds.”   

  

“The Crab Bank restoration effort is a perfect example of what agencies, nonprofits, businesses, local leaders, students, and citizens can accomplish for conservation when they work together,” said Laura Cantral, Executive Director of the Coastal Conservation League. “This project touches much of what Lowcountry residents hold dear, including protecting wildlife and our unique coastal ecosystems, enhancing our hospitality industry, and strengthening communities and education. When the work is done, 5,000 or more birds will return every season to nest on the island, making Crab Bank once again a visible indicator of the healthy, vibrant coast we love.” 

  

Major corporations such as Boeing SC, BP, the Post & Courier Foundation, the S.C. Ports Authority, and hundreds of individual citizens in the Charleston region contributed funds to support the restoration of Crab Bank and the S.C. Coastal Bird Conservation Program’s broader mission. An effort led by students at Moultrie Middle School in Mt. Pleasant added $675 to the total funds raised – which to date is more than $700,000. In addition to the private funds raised, a $700,000 grant awarded to Audubon South Carolina by the National Fish and Wildlife Foundation’s Coastal Resiliency Grant Program took fundraising efforts across the finish line and ensured that Crab Bank will be restored. Any additional funds will go toward monitoring and stewardship of the island. 

  

“Thanks to everyone’s efforts, brown pelicans, black skimmers, royal terns, and so many other species will once again have a safe place to rest during migration and nest during the summer in Charleston Harbor,” said Nolan Schillerstrom, Coastal Programs Coordinator for Audubon South Carolina. “Many of these birds suffer deeply from limited habitat, but with Crab Bank restored, we’re taking a big step in the right direction.” 

  

“The Coastal Expeditions Foundation is proud to be part of the task force that assembled and fought for the salvation of Crab Bank Island,” said Coastal Expeditions Chief Steward Chris Crolley. “The Crab Bank initiative and the creation of the S.C. Coastal Bird Conservation Program is some of the most important work we will do in our lifetimes.”     

  

“The collaboration and partnerships that were strengthened while the community secured funds for Crab Bank is invaluable and inspiring,” said Felicia Sanders, seabird and shorebird biologist for SCDNR. “This project not only built a nesting island for thousands of birds, but also resources and advocates to continue working on coastal bird conservation for many decades to come.” 

 
 

Project Timeline: 

Complex engineering projects like this one take years to plan and execute. It may be 2021 before full restoration of Crab Bank occurs, and many factors can influence the outlook for completion of the work. However, the important thing is that the process is moving forward, and long-term, this is a big win for South Carolina’s coastal birds. 

  

Before the last blow from Hurricane Irma in 2017 that washed away the remaining available high ground for nesting, Crab Bank was not only a critical nesting and resting spot for coastal birds, but also a popular attraction for thousands of paddlers and birdwatchers — an integral part of a thriving local tourism economy centered around Shem Creek’s shops, restaurants and outfitters. Overall, coastal tourism contributes an estimated $9 billion per year to South Carolina’s economy — a cash infusion that depends in no small part on healthy, abundant wildlife populations. 

  

Make no mistake about it, the S.C. Coastal Birds Conservation Program and SCDNR are in this fight for the long haul. Scientists estimate that shorebird populations have shrunk by as much as 70 percent across North America since 1973, and South Carolina provides the majority of habitat for entire populations of a number of seabirds, shorebirds and wading birds. Efforts to conserve birds in South Carolina can and will help region-wide populations rebound. Individuals interested in supporting or learning more about this important endeavor will find more detailed information on the Coastal Bird Conservation website: [https://www.sccoastalbirds.org/]. 

  

In the meantime, SCDNR is continuing to work on coastal bird management, education and research.  Donated funds will help with those efforts.

Crab Bank is a crescent of sand in Charleston Harbor that once supported an astonishing number of nesting
birds — up to 5,000 in a single summer and thousands of offspring. It also provides rest and nourishment for
hundreds of migrating shorebirds.

A slice of true wilderness in our bustling urban harbor, Crab Bank provides tremendous economic, recreational, and educational benefits for Charleston.

 

But wind and waves have taken a toll on this unique resource. Created in the 1950s from sand dredged from
the harbor, Crab Bank is now a tiny fraction of its original size. In 2017, Hurricane Irma washed away most of
the remaining high ground, removing any opportunity for nesting birds in 2018.

Happily, there’s a solution. In 2019, the US Army Corps of Engineers will dredge the Charleston Harbor to make
room for larger ships, allowing us to deposit dredged sand on Crab Bank. This will require an estimated $2
million local investment, plus potentially more than $3 million in federal funds.

 

The restored bird sanctuary will be a spacious 28 acres, with plenty of high-ground nesting habitat. The Corps
of Engineers estimates that it will take half a century for Crab Bank to erode back to a half-acre in size —
enough time to hatch tens of thousands of young birds.

 

The Charleston Harbor dredging provides an extraordinary opportunity to restore Crab Bank. But there’s no
time to lose — if we miss this opportunity, there may not be another one for decades.
Coastal birds and
everyone else who benefits from Crab Bank’s presence in the harbor, including businesses on Shem Creek,
homeowners in Mount Pleasant, and children throughout the Charleston area will lose an essential symbol of
Charleston Harbor.
