Major Skimmer Island Restoration Project Underway

Major

OCEAN CITY — Work began this week on the dredging of a navigation channel at the entrance to a West Ocean City marina in a plan that includes depositing the dredged material on Skimmer Island just north of the Route 50 bridge in an effort to restore critical nesting habitat for a handful of threatened species.

In a continuation of a project that began two years ago, the Maryland Coastal Bays Program, in conjunction with the Maryland Department of Natural Resources (DNR), the Ocean City Fishing Center and Hi-Tide Marine this week started to work on a project to restore and replenish the large, low-lying island north of the Route 50 bridge known popularly as Skimmer Island.

The project includes dredging the silted-in entrance to the Ocean City Fishing Center just south of the bridge and depositing the dredged material on Skimmer Island just north of the span. The project essentially serves two purposes with the first being clearing the entrance to the marina, which fills in each winter due to natural processes. The second, and perhaps most important, element is pumping the dredged material onto Skimmer Island, a sandy, crescent-shaped spit of land just to the north of the bridge, which has eroded over the years to become a fraction of its former self.

“The dredging is a cooperative venture between the marina and the DNR,” said Dr. Roman Jesien of the Maryland Coastal Bays Program. “The marina is funding the dredging to maintain their approach channel, and the DNR needs sand to maintain Skimmer Island, which has been eroding in recent years.”

The project has been undertaken in each of the last three years, but a series of harsh storms including Hurricane Sandy last October and a strong nor’easter just two weeks ago have made it more important than ever this year. For example, last year about 600 cubic yards of sand were pumped from the Fishing Center channel onto Skimmer Island, but this year, the project calls for the pumping of around 4,000 cubic yards of material, according to Jesien.

“Super Storm Sandy and the recent nor’easter caused considerable erosion to the island, which rendered it too low in elevation to accommodate nesting royal terns and black skimmers, which are state endangered species,” he said.

Skimmer Island serves as a temporary home and nesting place for several species of colonial nesting birds, most notably the Black Skimmer and the Royal Tern, both of which are considered endangered in Maryland.

Black skimmers are short, stubby black and white birds that skim the surface of the water with the lower mandible of their orange and black razor-like beaks as they search for fish near the surface. The royal terns, also black and white, are similar but have a forked tail.

Both species are bare-ground nesting birds that require a sandy area free of predators to lay eggs and raise their young. Nesting is perilous as the birds lay their eggs just above the high tide line and must hatch and raise their young before high tides and storms wash away their temporary nesting areas.

However, the two species have seen their traditional nesting areas in coastal areas of Maryland decline rapidly in recent years to the point they are in danger of disappearing from the state’s ecological landscape. For example, in 1985, as many as 300 pairs of Black Skimmers nested and reproduced in various coastal areas of Maryland, but in recent years, the figure has dropped to as few as 25 pairs with dismal or no reproductive success. Similar figures bear out for other species such as the royal terns.

Part of the problem locally is the decline of natural islands and spits of land in the coastal bays suitable for bird nesting. Most of the small islands in the bays naturally migrate from year to year as sand is washed away from some areas and deposited in others. However, a variety of natural and man-made factors have changed the equation.

For example, when Skimmer Island was surveyed in 1998, it measured 7.1 acres. In 2003, it had been reduced to 5.6 acres, and in 2007, it was down to 3.9 acres, or roughly half the size it was a decade earlier. In the most recent survey, Skimmer Island had been reduced to just 2.7 acres. Jesien said this week the annual pumping of the dredged channel material onto the island is an attempt to restore Skimmer to its former size, or at least maintain it.

“The sand placement is designed to raise the elevation of the island to maintain areas above high tides so that the birds can nest and raise their young,” he said. “The islands in the coastal bays are the only nesting sites for these birds in Maryland. Once the birds return to Skimmer Island in the spring, the island will be closed so as not to disturb them as they nest and raise their young.”

Staging work began this week with a large boom set up to pump sand from the channel on the south side of the bridge to the island on the north side. The dredging is expected to be completed by April 1 in order to protect young summer flounder and spawning horseshoe crabs that will soon enter the coastal bays, but site work might continue on the island until mid-April. Although the area is popular for clamming, the public is urged to keep off the island while the birds are nesting so that they are not disturbed during the critical time in their life cycle.

  1. All sounds good but there is other problem they are causing.The channel at end of stinky beach was dredged and has caused water to erode shore line and slowly under mining homes.That channel now is 50 ft deep current so strong threw there it is pulling sand from shore.channel needs to be moved out from shore line.As a resident of oc for 50 years I see change in channel.Te homes at end of stinky beach now have to pay price because channel was moved or subject to erosion.Estimated cost to bulk head would be 1.5 million for 4 homes.Who should pay this price?For dredging channel to close to begin with.

  2. That area has never been dredged. It’s the areas further north west that are effected. If you had spent ttime in that are you would notice that scouring has only started to occur as the middle of the bay started to fill in.
