Big Egg Marsh Restoration:
Pilot Project To Begin at Jamaica Bay Wildlife Refuge
back to top
George Frame

The National Park Service’s (NPS) Gateway National Recreation Area is preparing to implement a pilot salt marsh restoration project at Jamaica Bay Wildlife Refuge’s Big Egg Marsh. Natural resource scientists from Gateway’s Division of Natural Resources (DNR) and Jamaica Bay Unit, and New York State Department of Environmental Conservation (NYSDEC) developed the Big Egg Marsh project as a small-scale experimental restoration. The project objectives are to evaluate: (1) results of a new method of sediment transfer and placement used to increase marsh elevation, (2) growth of marsh vegetation through a thin layer of sediment, and (3) pre-treatment and post-treatment inventory and monitoring information. The project, scheduled to begin in late August 2003, was planned in response to the extensive salt marsh losses and associated degradation in Jamaica Bay first reported by the State of New York.

According to NYSDEC’s 2002 report, Jamaica Bay’s protected salt marsh islands halved in area since 1924, when 2,300 acres existed. The marsh islands have experienced an accelerated loss from 26 acres per year in the 1970s to the current 44 acres per year. This loss is occurring in a protected wildlife refuge, and does not include the known losses from deliberate landfill and urbanization that took place along the bay’s periphery. The disappearance of the marshes is alarming, primarily due to their multiple functions and values, which include, but are not limited to high biological productivity, diverse recreational opportunity, flood buffering capacity, aesthetics, and the ability to store carbon and sequester chemical contaminants.

In May 2001, a Blue Ribbon Panel of salt marsh specialists assembled by the NPS concluded that the likely causes of salt marsh loss include: decreased availability of sediments (due to paving, bulkheading, and dredging), sea level rise, erosion (due to waterfowl rooting, mosquito ditches, boat wakes, and subsidence), plant mortality (due to impeded drainage, chemical contaminants, pathogens, smothering from mats of straw and sea lettuce), and the isolation of the bay from sediments as a result of natural lengthening of the adjacent barrier island. The panel suggested pilot projects involving research and trial salt marsh restoration. In response, the NPS developed a three-pronged approach to the problem: protection, restoration/in-vestigation, and education. The Big Egg Marsh pilot project will serve primarily as an investigative / restorative effort. In addition, a wayside educational component has also been incorporated to enhance public understanding and cooperation.

The restorative component of the project was designed, in part, to evaluate “thin-layering,” a relatively recent method of sediment application for tidal marshes, as a means of re-establishing salt marsh vegetation and increasing the overall elevation of the deteriorating marshes. In Big Egg Marsh, a thin layer of sediment will be applied via Jet-Spray method. This pressurized spray method provides an even distribution of sediment particles, thus reducing the turbidity that results from the loss of smaller particles that are more easily transported by the conventional sand slurry method. The two acres of thin layer spray applied to the marsh surface will vary from a few inches in depth near the marsh edge to a maximum of several feet over the ditches and depressions in the marsh interior. The thicker, interior layer will form a ridge that will be up to 10 inches higher than the surrounding areas of lesser depths. The highest point on the ridge will be several inches below the lowest elevation of common reed (Phragmites australis), which grows at a nearby, off-site location.

The preferred alternative for minimizing ecological impacts during the restoration process is to dredge sediment from the intertidal creek adjacent to the south and west sides of the treatment area of the marsh. The sediment, consisting of about 90% sand, will be extracted from the bottom of the intertidal creek bed. The dredging will form a 20-foot-wide, 6-foot-deep, and 300-yard-long trench. The approaches to both ends of the creek channel will not be dredged and will remain as intertidal mudflat.

The investigative component of the project includes pre-treatment inventory and monitoring. Pre-treatment inventory includes a soil invertebrate survey (qualitative and quantitative), aquatic macro-invertebrates, contaminant sampling, insects, spiders, fishes, birds, and mammals. In addition, soil samples were collected for pore-water analysis to compare the chemistry of bare soil with the soil of the remnant patches of smooth cordgrass. Monitoring the above-mentioned parameters will continue for at least 5 years as other, larger scaled projects are planned and implemented.

Results of the project will be used to guide future restoration efforts, which will also focus on enhancing deteriorated salt marsh ecosystems. The salt marshes are an integral and fundamental habitat type of Gateway’s coastal ecosystem. It is among the most highly productive salt marshes in the Northeastern United States and recognized internationally as an Important Bird Area. The refuge supports critical feeding, resting, and nesting habitats for more than 300 species of migratory and resident birds observed to inhabit the bay. The intertidal and subtidal mudflats adjacent to the salt marshes support nurseries for fishes, marine invertebrates, and shellfish.

Exploring Estuary Education Updating the
Harbor & Estuary Program’s Teacher’s Guide
back to top
Kate Johnson

One of the main goals of the Harbor & Estuary Program is to increase public awareness and appreciation of the environment that surrounds us. We have found that one of the most effective ways to accomplish this goal is by reaching out to some of our most enthusiastic citizens– students and teachers. An estuary’s role as a transition zone between land and sea, as well as between fresh and salt water, make it an ideal research laboratory for scientists and students alike. As estuaries are some of the most productive ecosystems on earth, the wealth of plant and animal life found in estuarine environments far surpasses those found almost anywhere else. Environmental problems affecting our coastal resources mimic those that affect many of our valuable natural resources. All of these aspects combine to make estuaries an invaluable teaching resource.

Teacher’s Guide Release

Currently, HEP is in the process of updating, expanding and improving its Teacher’s Guide to Water Education Resources, which will be titled Exploring Estuary Education: A Teacher’s Guide to Lessons, Activities and Field Trips in the Harbor Estuary. Due for release in the September, the new teacher’s guide will include an updated directory of organizations, including several new additions, that offer estuary-related programs, field trips, workshops or printed materials.

The new guide will also be expanded to feature a new section dedicated to materials that teachers can use directly in their classrooms. This section will contain teacher and student fact sheets, maps of the local estuary, estuary vocabulary, descriptions of native wildlife, a list of relevant internet resources and numerous sample lessons and classroom activities provided by local organizations. We hope this section will encourage teachers to include estuary education in their lessons, as well as highlight local organizations that have curriculum materials available. Our first teacher’s guide received a terrific response from local educators and we are sure that the new, expanded edition will be equally well received.

If you are interested in receiving a copy of Exploring Estuary Education: A Teacher’s Guide to Lessons, Activities and Field Trips in the Harbor Estuary as soon as it is available, please call 212-637-3816 or send e-mail to info@harborestuary.org.

Kate Johnson, EPA Intern, has been working to update and expand the Harbor & Estuary Program’s teacher’s guide this summer.

Capt. Pete Says... Fish Tacos/Fish Fingers back to top
Peter L. Sattler

Fish on!! Every type of fish is in season and the bite is on! Striped bass, fluke and weakfish are running; and these fish are big. Small bluefish are stealing the bait, but I target the aforementioned game fish for their delicious taste. This fun meal involves preparing those big fillets into small, manageable bites. With this recipe, it’s alright to be like George Costanza: Double Dip!!

Fish Tacos:

3/4 C Flour

1/4 C Capt Pete’s Spice Mix*

12 Oz. Beer, Mexican preferred

2 C Flour or Wondra Oil for frying

3/4 lb Fish fillets cut into ~4” x 1/2” strips

2 Cloves of garlic

8 Tortillas, burrito size

1 C Salsa

* Equal parts of paprika, cayenne, salt, black pepper, garlic powder, chile powder, oregano.

Avocado Tartar Sauce:

2 Avocados, ripe

1/4 C tartar sauce

1 Tbsp lime juice

Puree avocados, stir in tartar sauce

and lime juice; chill.

Combine flour and spice mix. Dredge fish (First Dip) and set aside.

At the same time that the oil is heating (add garlic cloves), mix Wondra in the beer; make sure its not the one you’re drinking. As soon as the oil is ready (cloves will be brown--remove & discard), dredge fish in beer batter (Double Dip) and place in pan with room for the strips to swim. Turn once when golden brown and place on paper towels to drain. Continue until all fish strips are cooked; dispose of oil properly.

Heat tortillas - fill with fish, salsa, tartar sauce - roll - enjoy!

For an appetizer of Fish Fingers, skip the tortillas and serve the tartar sauce on the side.

Beverage of choice: Corona or Dos Equis or Modelo Negra, served ice cold.

Peter L. Sattler is Principal Environmental Planner with the Interstate Environmental Commission.




Species Profile: Butterflyfish back to top
John Waldman

During summer and early autumn, the mostly drab-colored temperate fishes that dwell around the piers of New York Harbor mix with bright yellow visitors from down south: butterflyfish. These southerners appear perfectly capable of feeding and growing in the waters of the NY-NJ Harbor Estuary despite occurring many hundreds of miles north of the normal range of their adults. Most of the butterflyfish observed in the area are spotfin butterflyfish; however, foureye butterflyfish have also been caught.

The tropical fishes seen in the Harbor system occur there as a result of the surprisingly large masses of eggs and larvae of southern species that are carried to higher latitudes by the Gulf Stream each spring and summer. As the Gulf Stream curves northeastward, warm-core eddies spin off the main flow toward Long Island like storm systems, depositing these early life stages in large numbers in the island’s south shore bays. If you pull a seine net through the shallows of Shinnecock Bay in late summer, you will catch a remarkable array of juvenile fishes more often associated with the Bahamas. The Harbor Estuary doesn’t receive nearly as many of these expatriates, but noticeable numbers do occur there.

Butterflyfish will enter killifish traps baited with sardines and suspended off Manhattan piers—the River Project has taken them at Pier 26. But many tropicals also show up around the estuary in beach seines deployed for monitoring or educational purposes. Almost all are young-of-the-year because the eggs and larvae that produce them are the life stages least resistant to passive dispersal by currents. Other exotics that have been seen in the harbor and lower Hudson include ladyfish, bonefish, bluespotted cornetfish, gag grouper, short bigeye, moonfish, lookdown, permit, gray snapper, spotfin mojarra, pigfish, scrawled cowfish, and orange and planehead filefish. Given that the Harbor is a large, well-sampled estuarine system, new species additions seem to occur every year or two.

Alas, some of these tropicals may be out of their league. Divers have seen members of the slower swimming species dying after autumn cold snaps.

John Waldman, Senior Scientist with the Hudson River Foundation, also wrote about this phenomenon in his recent books: Heartbeats in the Muck and The Dance of the Flying Gurnards.
