The Effects of Beach Nourishment on the Natural Environment:

A review of scientific literature regarding the pros and cons of sand placement

By Patrick Amico, Conservation Biologist

IntroductionThe U.S. Army Corps of Engineers has been working to dredge the shipping channel immediately adjacent to Bald Head Island (BHI) this spring. This “maintenance dredging” is required to maintain the navigational depth of the shipping channel. The sand removed from the bottom of the channel is used to restore sand to the beaches of BHI. Bald

Head is supposed to receive sand every other year except for every 6th year when sand is placed on Oak Island. Unfortunately this does not always

occur on the time schedule originally agreed to by the Corps and the towns of Oak Island, Caswell Beach and Bald Head. Often federal funding constraints cause the disruption in the cycle of sand replenishment. On years without nourishment, the

Bald Eagles of Bald Head IslandBy Kendyll Goeman Collins, Environmental Educator and Outreach Coordinator

I often ask visiting school groups why they think Bald Head Island is called Bald Head Island. Their answers are usually “because bald people live here” or “because ‘bald head’ eagles live here.” Neither answer is correct! Of course, BHI was named when the river pilots rubbed the primary dune raw, on their quest to guide approaching ships. We don’t have any “bald head” eagles on the island, but we do have bald eagles (Haliaeetus leucocephalus)! Looking back through BHI C o n s e r v a n c y archives, bald eagles have been spotted on the island for many years. Before the fall of 2011, bald eagles only nested in Southport. They took day trips to BHI fish. From August-October 2011, BHI Conservancy staff saw a bald eagle pair flying all over the island collecting nesting materials.

to share the news- the bald eagles had nested! Bald eagles are one of the few monogamous animals in the entire animal kingdom! They mate for life and return to their nesting site each year. Bald eagles perform a breathtaking courtship ritual; they link talons and free fall to the ground- only letting go right before they crash! In 2011, the eagles successfully raised one eaglet. You may have seen the juvenile bald eagle perched by the island marina. Juvenile bald eagles are entirely brown in color. The nesting pair returned this year, added a massive addition to the nest, and successfully hatched 2 eaglets! Bald eagles are piscivores, or fish eaters. You’ll

often see them hunting and fishing around the salt marsh or Beach Access #1. Check out this amazing shot taken by BHI Conservancy Life Member and avid birder, Robin Prak. She took this picture of one of the eagles soaring over the Kent Mitchel Trail.

You may also see the eagles pestering shorebirds for their catch. Even though eagles are completely capable of catching their own meals, they’ll often go after another bird’s meal! This is one of the reasons why Benjamin Franklin did not want the bald eagle to be our national emblem. He believed it was a bird of immoral character. The eaglets just emerged and are still covered in down. Be sure to join BHI Conservancy staff for a Birding BHI, Island Nature Tour, or Middle Island Hike for a chance to see their nesting site.

New Programming!Tracey Ritchie, Director of Education

We are so excited with the arrival with warmer weather, more outdoor activities and more friends to the island! Our spring calendar kicked off April 1st with our first scheduled kayak trip of the year! It was hard to think of heading out onto the water during the cold, windy days, but we are grateful that the warmth has arrived. Also with April’s arrival we welcome back Beachcombing. But this isn’t your grandmother’s beachcombing… We have redesigned this classic program and it is more exciting than ever. Join us Thursday’s at 2PM in the Barrier Island Study Center for a quick intro into our investigation before heading out to the beach to see what clues we can find during CSI: BHI- Beachcombing Edition.

In addition to the new programs, be sure to make time for some old favorites that you should take advantage of before the summer months bring warm muggy weather and all those mosquitoes. Before it gets too humid, join us for a Maritime Forest Hike or a Middle Island Hike on alternating Fridays through April. We highly recommend exploring these habitats during the spring months to see what natural treasures you might find!

Monday morning birding shifted to 8:30AM on April 1st. Don’t oversleep and miss out on seeing some of our favorite migratory birds, the bald eagles and hopefully any day now we will be welcoming back the painted bunting! Last year we saw their arrival on April 15th, so be on the look out!

Please check out our full calendar of events on our website at www.bhic.org/calendar-of-events to see all that is going on and when! Almost all of our programs have online registration, but for any other questions or registration information please call 910-338-0930.

One question you may be asking yourself is, “How on Earth can Kendyll and Tracey lead all of these programs??” The answer is: We Can’t! We need your help! We are looking to train a team

of Volunteer Educators to help lead any and all of our education programs.

sand from the ‘Point’, where BHI’s West and South Beach meet, slips into the channel causing non-natural and accelerated erosion rates.

Economic Impacts:Many beaches along the east coast of the United States depend on nourishment to maintain the historic beachfront. Nourished beaches provide better storm buffers and thus protect infrastructure and housing. Nourished beaches are also better for tourism because of the demand for broad beautiful beaches. In some areas of the country, nourishment projects have been known to double or triple property values. According to a report by the American Shore and Beach Preservation Association (ASBPA), in 2006, more than one half of all Americans lived in

coastal counties. That means half of us are crammed into an area that makes up less than 17% of the land in the lower 48 states. Coastal areas receive 3,600

new residents daily, and over the last thirty years, 19 million homes have been built there, currently at a rate of 1500 homes per day. An estimated 180 million people vacation at the coast every year, spending billions of dollars and supporting 2 million jobs associated with tourism. In 2003, coastal watersheds generated $6 trillion dollars nationwide, with the tourism industry being our nation’s largest employer and fastest growing economic sector (ASBPA 2007). Nearly every developed beach in New Hanover and Brunswick County participates in beach nourishment cycles. The demand for beach renourishment will continue to increase with climate change and associated sea level rise.

Environmental Impacts:While beach nourishment projects are costly, their economic benefits seem to justify the investment. Examining nourishment from an environmental perspective turns out to be a bit more complicated. Positive environmental outcomes of nourishment include, protecting endangered dune plants, safe-

guarding back dune habitat, and creating or restoring habitat lost for nesting sea turtles, shorebirds, and other beach organisms. But negative outcomes have also been observed.

The borrow site, where sand is removed, is disturbed both by the removal of bottom habitat and also by impacts to water quality, noise, and current patterns. Increases in the turbidity or suspended sediment in the water can cause fish populations to temporarily move away from an area. If the bottom was a host to marine organisms, food webs can be permanently disrupted. Noise of the operation and physical contact by equipment can disturb marine mammals and sea turtles. Sea turtles have been sucked into dredge equipment and killed in past projects. Dredging alters wave patterns and sediment transport, changing the sea floor texture, water circulation, and nutrient availability. (Greene 12,14,15,21; Wilgis 4). In the Bald Head Channel, the bottom is sandy and does not host much in the way of food for fish or turtles. The water is fast moving from tides moving in and out of the river mouth. When the channel is narrow from lack of dredging, currents can move so fast that sand is actually swept out into the ocean making it unavailable for nourishment.

Back on the nourished beach, the most directly affected organisms are animals on the sand. Invertebrates such as mole crabs and coquina clams serve as food sources for fish populations and shorebirds. The addition of the new layer of sand harms these organisms, and heavy machinery used to shape a beach can kill these food sources (Speybroeck et al., 421-422; Greene 22-24).

On Bald Head we are interested in how our nourishment might be impacting the invertebrates and the fish that feed on them. Ryan Walsh, a former BHI Conservancy intern is working in collaboration with the BHI Conservancy to examine the differences in fish and invertebrate diversity and abundance in the near-shore beach environment. Since the summer of 2012, this study has observed four study sites across the island. A natural beach (East beach), a renourished beach (South beach), a

continued on page 5

Beaches...continued from page 8

renourished beach with the presence of groins (2nd South beach site), and a river-influenced area (West beach) are included. The BHI Conservancy will use information from this study to help the island tune beach management during and after nourishment to minimize negative impacts on fish and bird populations.

Since nourishment this year is extending well into the spring the BHI Conservancy is also examining the impacts on shorebirds. Noise during construction

can affect foraging bird species (Speybroeck et al., 422). During the current nourishment on Bald Head Island, citizen scientists are participating in a SEANET project to

record the activity and loss of birds on the beach. To date, they have reported seeing fewer birds on the areas of beach in or adjacent to the sand placement zone.

Of course the island is very interested in protecting nesting sea turtles on BHI beaches. Nourished beaches can form scarps (steep cliffs), which impede nesting sea turtles. Scarps just 18 inches high can interfere with nesting turtles by creating a barrier to nesting areas, causing them to return to the sea without nesting. (Wilgis 12). The BHI Conservancy works with the Village of BHI to knock down any scarps that form during turtle nesting season.

In addition to scarps, beach nourishment makes the beach less steep in profile, some researchers believe that the decreased angle makes artificial light on the beach even more perceptible to emerging turtles, increasing distractions and false crawls.

The greatest impacts to sea turtles occur when nourishment happens during nesting season. That is not the case with the current project on Bald Head Island, but in 2001, beach construction carried into July, and turtle monitors recorded double the normal ratio of nests to false crawls, with 77 turtle

nests laid and 125 false crawls (Wilgis 8).

Beaches that are nourished tend to be more changeable than natural beaches. This dynamic nature of the beach may be associated with decreased turtle nesting. A seven-year study on Jupiter Island, Florida concluded that sea turtles lay more nests on natural, un-nourished beaches (Steinitz et al., 1998). Typically a slight increase in attempted nesting is observed soon after a renourishment project, and in subsequent years a decline in nesting is seen when compared to non-nourished beaches. On BHI sand in the nourished area only lasts about 2 years.

Sand size and rocks can also have a strong negative impact on turtle nesting and hatchling survival. The NC Division of Coastal Management has put regulations to ensure that beach quality sand is the only type of sand used in nourishment projects. Before these rules were in place, in 2001 and 2002 the beaches of Oak Island and Pine Knoll Shores were nourished with coarse sand with lots of rocks. Too many rocks and shells deter sea turtle nesting and affect the incubation of turtle eggs and the ability of hatchlings to emerge from the nest (Wilgis 7).

In a report to the Atlantic Marine Fisheries Commission, Karen Greene classified the types of impacts from beach nourishment projects in three categories: direct, indirect, and cumulative (Greene 12). Direct impacts tend to be easier to measure, an example would be the loss of bottom dwelling animals living on the seafloor of the dredge site. Indirect effects are more difficult to quantify, an example would be a fish population moving away from dredged area because food sources are missing after nourishment. Finally, cumulative impacts arise from the past and present actions in an area, a combination of direct and indirect effects. These effects can be more serious than the effects of one particular beach nourishment project at one site at one point in time. An example of this would be an animal population is no longer observed in an area drastically changed by repeated nourishment. The thirty-year sea turtle nesting data collected by the BHI Conservancy is an important opportunity for scientists to begin to understand potential

Island Nature Tourscumulative impacts of nourishment. With understanding, tools can be developed to help turtles take advantage of nourished beaches as natural beaches become more and more rare.

ConclusionBeach nourishment comes with pros and cons. Property values are increased and healthy beaches are vital tourism and storm resiliency. Several endangered marine organisms depend on the beach for their way of life. Living in harmony with nature means balancing the benefits and costs to these animals along with the economic needs of our community. Monitoring and research like: SEANET, Sea Turtle Protection Program, Fish and invertebrate study, and dune monitoring will aid in providing real answers about how to protect our beaches and the creatures we share it with.

Critical Habitat Designation does not impact BHI beach planning or sand bagging permits

By Suzanne E. Dorsey, Executive Director

The US Fish & Wildlife Service has designated Bald Head Island as “Critical Habitat” for the loggerhead turtle. It recognizes that the island is one of the best places in the state for nesting sea turtles. It also emphasizes the need to protect these important habitats as sea turtle populations continue to struggle.

Several island entities have approached the BHI Conservancy to ask what this new designation might mean for the Island. Specifically, what does it mean for private property owners, public access, and for the Village’s plans to protect the shoreline from damage caused by the Army Corps of Engineers Channel.

In response to a query from the BHI Conservancy, the U.S. Fish & Wildlife’s National Sea Turtle Biologist in Jacksonville Florida responded that the island is already in compliance with all federal regulations to protect endangered sea turtles. As the index beach for North Carolina we actually go far beyond federal or state requirements. Our saturation-tagging program that intercepts every nesting sea turtle mom is the only one in the state. When forced to relocate a nest for protection against erosion or storms, we have the highest hatching rates from a disturbed nest. In general hatchlings that emerge from our beaches survive in greater numbers than our neighboring beaches.

Since Bald Head is a model sea turtle conservation community, there will not be any new hurdles or limitations for individuals or for our Village responding to erosion crises. The designation recognizes our importance to the state but does not limit access to the beach. The designation will require the state U.S. Fish & Wildlife staff to confirm that we meet current requirements. That confirmation will not place any additional burden

on private citizens or the Village of BHI.

The message from U.S. Fish and Wildlife service was: BHI is doing a great job at protecting endangered species. The BHI Conservancy’s Sea Turtle protection program does this with no federal or state funding and our results speak for themselves. Your continued support through membership and participation in our education programs is much appreciated. The Conservancy staff and volunteers will continue to protect turtles and ensure that beach planning and emergency response to erosion is supported by internationally recognized conservation efforts.
