Redden State Forest project is part of Chesapeake Bay restoration effort

Delaware has over 2,000 miles of tax ditches according to the U.S. Fish and Wildlife Service.

The long-term battle to restore the Chesapeake Bay is quietly being waged right here – on the Deep Creek Tract of Redden State Forest in Georgetown, near the intersection of Rum Bridge Road and Rt. 404/18. That’s where Guy Cooper and Mike Green of the Delaware Forest Service are using heavy equipment to carefully move soft, sandy soil along the placid, sun-dappled waters of the nearby tax ditch. The methodical work is part of a proven strategy to lower the bank level in 17 key locations as a way to “reconnect” the artificial waterway to its natural floodplain. The new configuration will allow water from excessive rainfall events to overspill the banks and flow into nearby woodlands, letting the forest serve as a natural filter by absorbing excess sediment, nutrients, and pollutants.

The Delaware Forest Service's Guy Cooper uses an excavator to carefully move soil along a tax ditch on the Deep Creek Tract of Redden State Forest.

The project is one thread in the wider fabric of the Nanticoke Watershed Restoration Plan – a cooperative strategy to improve the health of the Nanticoke Watershed, a key contributor to water quality in the Chesapeake Bay. The effort has involved local tax ditch officials, nonprofit groups such as the Nanticoke Watershed Alliance, state agencies such as Delaware’s Dept. of Natural Resources and Environmental Protection (DNREC) and the Delaware Forest Service, and federal partners such as the U.S. Environmental Protection Agency (EPA), the USDA Natural Resources Conservation Service (NRCS), and the U.S. Fish and Wildlife Service.

Deep Creek is one of 15 watersheds that comprise the Chesapeake Bay Basin.

Deep Creek covers 63 square miles and comprises one of 15 sub-watersheds that constitute the Chesapeake Bay Basin. These areas contain headwater forests for the Nanticoke River that also serve as important wildlife habitats for an abundance of unique plants and animals. The cost – about $1,000 per cut-out depending on the amount of soil and material to be moved – is funded by a five-year grant from the EPA administered by DNREC that targets non-point source pollution.

 

The plan to reconnect channelized waterways to forested floodplains has been implemented successfully in the region before: U.S. Fish and Wildlife officials restored 600 acres along the Pocomoke River in nearby Maryland, and last year a project was completed in Redden State Forest in the nearby Gravelly Branch sub-watershed.

For private landowners, federal agencies like the NRCS offer financial and technical assistance programs such as its Wetlands Reserve Program (WRP) to incentivize private landowners to implement water quality projects such as planting trees along riparian areas. However, public lands such as those at Redden State Forest also offer unique opportunities for water quality restoration, according to Brian Jennings, Fish and Wildlife Biologist at the U.S. Fish & Wildlife Service’s Chesapeake Bay Field Office.

“Research shows that every one acre of flood plain can treat excess run off from four acres of agricultural fields” Jennings said. “In this project, we’re restoring 50 acres of floodplain, which works out to about 200 acres.”

According to Jennings, the natural hydrologic features of the connection points are designed to be triggered when the tax ditch channel achieves what is known as “bankfull discharge,” which would likely occur during a 1- to 2-year rainfall event – equivalent to approximately three inches of precipitation at a single time. Without the new cut-outs, a major storm would cause the ditch to act as a rapid conduit for excessive runoff from nearby fields and impervious surfaces: fast-tracking sediments, pollutants, and excessive nutrients downstream into the bay.

When the region is experiencing periods of lower precipitation, the advantages of the changes may not be always readily apparent, but they have proven worthwhile over the long haul.

According to Erich Burkentine, the Delaware Forest Service’s regional forester in Sussex County, the effort is showing signs of success: “It’s definitely working the way it is supposed to. Now that we’ve had a bit more rainfall this year than recent years, we can see how the water has been diverted into the woodlands in places where the reconnects have been installed.”

Though the project is just a small part of the overall Chesapeake Bay Watershed restoration, Jennings is quick to acknowledge one of the program’s key partners – managers of the local tax ditch associations – who must give approval to install the new structures after receiving assurances that the newly-reconfigured banks will not destabilize existing tax ditch right-of-ways.

In addition to improved water quality, reconnecting the channels can help reduce flooding downstream and also provide habitat for key species that thrive in forest wetland ecosystems.

“We’re trying to restore the natural function of the forests in the flood plain. Not only do we want good water quality, but that will also translate into quality wildlife habitat,” Jennings said.

DNREC Fish & Wildlife Enforcement Blotter: May 21-28; Reminder for the week: Visitors to C&D Canal area encouraged to observe new rules

DOVER (May 31, 2013) – To achieve public compliance through education and enforcement actions that help conserve Delaware’s fish and wildlife resources and ensure safe boating and public safety, DNREC Division of Fish & Wildlife Enforcement agents between May 21 and 28 made 1,936 contacts with anglers, hunters, boaters and the general public, including 295 boating safety/fishing regulation compliance checks. Agents responded to 85 complaints and issued 69 citations, five of which were associated with increased Fish and Wildlife Enforcement presence at the C&D Canal Conservation Area (formerly the C&D Canal Wildlife Area) and the associated recreational trail currently under construction. Incidents of particular note included: 

  • Late at night on May 24, Enforcement agents responded to a boating accident in which a 22-foot Four Winns cabin cruiser collided with a stone jetty at the mouth of the C&D Canal. The severely-damaged vessel was estimated a total loss. The vessel’s operator, Gregory Mount, 46, of Essington, Pa., was cited for one count of negligent operation. A passenger who appeared to have suffered minor injuries received first aid from responding volunteer EMTs from the Delaware City Fire Company, but declined additional medical treatment. The vessel was recovered the next day by a salvage company. 

Citations issued by violation type included the following, with the number of charges in parentheses: 

Wildlife Conservation: Operating a motor vehicle off an established roadway in a state wildlife area (3), and damaging state property in a wildlife area (2), New Castle County; Trespassing after hours in a state wildlife area (2), Sussex County. 

Fisheries Conservation: Recreational: Unlicensed fishing (24), New Castle, Kent and Sussex counties; Possession of undersized blue crab (1), Kent County; Illegal use of non-circle hooks for fishing during striped bass spawning season (2), possession of undersized weakfish (6), unlawful possession of river herring (2), over-the-limit recreational crab pots (1), and possession of undersized Atlantic croaker (1), Sussex County.

Boating Safety: Operating a vessel with insufficient number of life jackets aboard (3), and no ramp certificate (2), New Castle and Sussex counties; Operating an unregistered motor vessel (4), Kent and Sussex counties; Negligent operation of a vessel (1), New Castle County; Insufficient visual distress signals (2), Kent County; No life jacket on child age 12 or younger as required by law (1), operating an unregistered motor vessel (1), water skiing without required observer (1), operating personal watercraft without required fire extinguisher (1), no boating safety certificate (3), and allowing use of non-compliant vessel (1), Sussex County. 

Public Safety: Clamming in polluted area (3), New Castle County.

Other: Lewdness (1), and failure to signal intention (1), Kent County; Littering (1), Sussex County.

Are you AWARE?

The Division of Fish and Wildlife Enforcement Section asks visitors to the 5,100-acre C&D Canal Conservation Area (formerly the C&D Canal Wildlife Area) near St. Georges to be patient and comply with new rules – some of which are temporary – while construction on the new Michael Castle Trail proceeds. To ensure public safety, agents are strictly enforcing regulations prohibiting motor vehicle access to the trail and encouraging visitors to park in designated areas and walk. 

Designed primarily for walking, jogging, bicycling, and horseback riding, the Michael Castle Trail has been in the planning phase for more than seven years, during which numerous public comment sessions were held regarding its design and location. 

New permanent gates have been installed to restrict motor vehicle access to the completed portions of the trail. Gates on the north side of the canal are currently closed, restricting access to the lower tier road from the eastern-most point near the branch canal at Delaware City through and including the Summit Marina area. 

Until construction activities are complete, access on the upper tier roads between the Gunning Bedford School and Summit Marina will also be restricted limiting access to the ponds near the railroad bridge. Once construction is complete, vehicles will still be permitted to access most upper level roads for hunting and fishing activities. 

The C&D Canal Conservation Area encompasses the north and south banks of the canal and part of the eastern shoreline of the Delaware River. The conservation area also offers hunting and fishing opportunities, boating access, and the Summit Retriever Training Area. 

The DNREC Division of Fish and Wildlife recognizes and thanks the majority of anglers, hunters and boaters who comply with and support Delaware’s fishing, hunting and boating laws and regulations. Citizens are encouraged to report fish and wildlife and boating violations to the Delaware Fish and Wildlife Enforcement Section by calling 302-739-4580. Wildlife violations may also be reported anonymously to Operation Game Theft by calling 800-292-3030 or online at www.dnrec.delaware.gov/fw/Hunting/Pages/OpGameTheft.aspx.

New artificial bait developed by U of D from project funded by DNREC could reduce number of horseshoe crabs used to catch eel and whelk

LEWES (May 29, 2013) – A new alternative bait product that will help reduce the number of horseshoe crabs harvested from the Delaware Bay was introduced today. A team of University of Delaware researchers led by Dr. Nancy Targett, DuPont scientists, fisheries biologists, watermen and conservation groups were joined by DNREC Secretary Collin O’Mara to make the announcement this morning at UD’s Hugh R. Sharp Campus in Lewes. 

For years, commercial eel and whelk fishers have dealt with a dilemma: They know the best bait to attract eel and whelk, locally known as conch, is a female horseshoe crab. However, harvest limits are in place to protect the Delaware Bay’s horseshoe crab population and the threatened migratory shorebirds that depend on their eggs as a food source. Commercial fishers have long worked within these limits, dividing each bait crab into pieces to bait multiple eel or whelk pots. 

“Horseshoe crabs are an ecologically and economically important species in the Delaware Estuary, which hosts the largest concentrations of horseshoe crabs in the world,” said Governor Jack Markell. “This alternative bait is the result of a great partnership among academic researchers, scientists, government, a private corporation and the commercial fisheries industry. By working together, they have found a solution that has great economic and environmental benefits, both now and for the future of bait development.” 

“Conserving and restoring horseshoe crab populations is critical to supporting Delaware’s shorebird migration and implementing the vision of the Delaware Bayshore Initiative,” said DNREC Secretary O’Mara. “By using this new bait developed by leading scientists at the University of Delaware in partnership with DNREC, watermen will be able to reduce the number of horseshoe crabs used to catch whelk and eel, enjoy more convenient bait storage, help conserve the horseshoe crab population, and support migratory birds that depend on horseshoe crab eggs for food. I applaud my predecessor, Secretary John Hughes, and Dean Nancy Targett for their vision to launch this innovative effort, which will provide a win-win for both the economy and the environment for years to come.”

The new bait came after years of research, which was spurred in part by a surprising fact: Eel and whelk do not typically feed on adult horseshoe crabs in their natural environment, yet they find them hard to resist in baited pots. 

That disconnect intrigued Targett, director of Delaware Sea Grant, dean of UD’s College of Earth, Ocean, and Environment and an ecologist who studies the chemical cues that influence animal behavior in the sea. She and her research team set out to identify the mysterious “scent” that lures in eels – and come up with a bait alternative to horseshoe crabs, which have experienced population declines in recent decades. 

After years of research, Targett and her colleagues have developed a recipe for just such an artificial attractor that could help reduce the number of horseshoe crabs commercial fishermen use.

“Our hope is that this new bait will meet the fishing community’s needs and at the same time protect the horseshoe crab,” Targett said. “Delaware Sea Grant’s motto is ‘Science Serving the Delaware Coast,’ and we are grateful that so many partners shared in that spirit to move this project forward.”

Horseshoe crabs – which are actually more closely related to spiders than crabs – feed upon marine worms and small shellfish, and are fed upon by the federally threatened loggerhead sea turtle and a number of shark species. Their outer shells often support a whole community of marine life, from bacteria to blue mussels. Horseshoe crab eggs are a key part of the seasonal diet of at least seven commercially and recreationally important fish species and a host of crabs and other invertebrates. 

Each May and June, horseshoe crabs lay large numbers of these small green eggs on Delaware Bay beaches. Migratory shorebirds, such as the endangered red knot, arrive around the same time to feast on surplus eggs before continuing their long journey from South America to their Arctic breeding grounds. In about two weeks, the birds double their weight for the final non-stop leg of the trip. 

As horseshoe crab populations dropped considerably in the 1990s, so did the numbers of red knots. With the horseshoe crab decline largely attributed to their increased demand as bait in the commercial whelk pot fishery, the Atlantic States Marine Fisheries Commission (ASMFC) established a fisheries management plan with strict harvest quotas. Since the plan was adopted, increases have been noted in segments of the horseshoe crab population. Currently, the ASMFC plan allows for harvesting a limited number of male horseshoe crabs and no harvest of female crabs in Delaware.  

With whelk as a popular seafood staple in Asia and an ingredient used domestically in chowders and fritters, demand for horseshoe crabs as bait continues to be high, particularly for female crabs, making an equally effective alternative appealing both economically and environmentally. 

To reach the goal of finding an alternative bait, Targett partnered with DuPont scientists to analyze the horseshoe crab’s chemical makeup. They identified 100 compounds in tissue samples and were able to rule out some as key components in the scent that appeals so strongly to eel and whelk. 

“We were pleased to provide the expertise of DuPont scientists, as well as business advice to make this project successful,” said Gary Spitzer, DuPont senior vice president of operations and engineering. “This is a great example of the way corporations, universities and governments can collaborate to promote sustainable solutions.” 

Concurrent with the chemical approach, Targett’s lab developed artificial bait made from alginates (compounds found in brown seaweeds and kelp), a small amount of coarsely ground horseshoe crab and food-grade chemicals including baking soda and citric acid. When mixed together, these ingredients form a quick-set gelatin that keeps for up to four days.

Compared with using half of a female horseshoe crab, which is the Delaware limit, the mixture was just as productive in catching eel using only one-eighth of a female. By substituting an invasive species, the Asian shore crab, the researchers cut that amount down to as little as one-sixteenth of a horseshoe crab. They tested catching whelk with the bait and found similarly successful results. 

In addition, despite speculation that female horseshoe crabs were better baits than males, the scientists found that artificial baits composed of males or females were equally effective. The Delaware limit is one whole male per trap or pot. 

The bait research was funded by Delaware Sea Grant, the Delaware Department of Natural Resources and Environmental Control (DNREC) and DuPont Chemicals & Fluoroproducts. A faculty member at the Delaware Biotechnology Institute participated in the early stages of the research. DNREC provided logistical assistance in obtaining horseshoe crab specimens and connecting researchers with fishers. 

LaMonica Fine Foods in Millville, N.J., has started producing the bait commercially. Field tests in Delaware Bay with local whelk fishermen have been successful so far. 

“The hallmark of this bait is that everyone wins,” said Jim Roussos of LaMonica Fine Foods LLC. “This is a major step in conserving the natural resource of horseshoe crabs. The conch and eel fishermen are relieved of the pressures of buying, storing and processing horseshoe crabs. The University of Delaware has proven once again that it is a vital, important and valuable institution not only to its students but to the public at large. And commercial fisheries win when we can be conservators of public resources while maintaining our historical way of life.”

Millsboro Inhalation and Biomonitoring Report finds air pollution coming into Delaware problematic; “Personal air,” indoor sources contributed most to toxic exposure

NEWS FROM THE DELAWARE DEPARTMENT OF NATURAL RESOURCES AND ENVIRONMENTAL CONTROL, THE DELAWARE DEPARTMENT OF HEALTH AND SOCIAL SERVICES AND THE OFFICE OF US REPRESENTATIVE JOHN CARNEY

DOVER (May 28, 2013) – US Representative John Carney, the Delaware Department of Health and Social Services (DHSS) and the Delaware Department of Natural Resources and Environmental Control (DNREC) announced the release today of The Millsboro Inhalation Exposure and Biomonitoring Study, Final Report. The report, sponsored by the Delaware Cancer Consortium and DNREC, and prepared by RTI International (RTI), was undertaken in response to residents’ concerns about cancer rates in the Millsboro area.  

Air and Biological Sampling
During the fall of 2011 and 2012, 35 Millsboro area residents participated in an inhalation exposure and biomonitoring study of PM2.5  (fine particulate matter that poses a health concern when levels in the air are high). Over a timeframe of three consecutive days in both 2011 and 2012, indoor, outdoor and personal air samples (the air breathed in a personal space) were analyzed for fine particulate matter both upwind and downwind of the power plant. Air samples were assessed for PM2.5 mass, and screened for environmental tobacco smoke and black carbon. Investigators also identified metals in the PM2.5, such as selenium, arsenic, mercury, nickel, lead, chromium and uranium. Environmental samples were supplemented by biological sampling of the participants for volatile organic compounds (VOCs) and metals. 

Key Findings of Air Sampling
Monitoring found that the largest impact on ambient air may be pollution carried by air currents from large urban areas outside the state. According to RTI, exposure levels did not increase with the operation of the nearby NRG Indian River power plant. 

Personal air and indoor sources were cited as contributing most to study participants’ exposure to PM2.5. – in fact, personal air concentrations of PM2.5 were statistically higher than outdoor concentrations. RTI found that personal air samples were influenced by the frequency in participation and intensity of common indoor activities, such as smoking, cooking, cleaning, and using personal care products.

“Delawareans have a right to know if they are being exposed to environmental toxins that could increase their risk of cancer and other health issues,” said Congressman Carney, a member of the Delaware Cancer Consortium. “The results of this study show the importance of monitoring potential sources of toxins both in Delaware and in states that are upwind of us.  It also reinforces that prevention and making healthy lifestyle choices, such as not smoking, are critical to avoiding these health issues before they start.  I’m very pleased to have played a role in completing this study – it will be a useful tool in planning the next steps in the fight against cancer.”  

Bromine was the only metal with personal air levels significantly higher than outdoor samples. Bromine likely comes from sources that are unique to indoor settings, such as flame retardants and environmental tobacco smoke (ETS).  Several potential indoor sources screened during the study, including tobacco smoke, require further sampling and data analysis to identify. 

PM2.5   exposure levels for indoor and personal air monitoring were not altered by the Indian River power plant emissions, the study found. 

“The results of this study clearly illustrate that we need to continue our focus on the key factors that contribute to serious health challenges in the state,” said DNREC Secretary Collin O’Mara. “We have made considerable progress in reducing toxic emissions by reducing pollution from power plants and large industrial facilities, but this study shows that this is not the whole solution and that we must further expand our efforts to reduce pollution coming in from upwind states as well as support efforts to help residents reduce personal and indoor sources of toxins.” 

DHSS Secretary Rita Landgraf said: “The role that the environment plays in people’s health will always be a complex puzzle filled with many variables. Thanks to funding from DNREC and the Delaware Cancer Consortium, and especially to the involvement of volunteers from the Millsboro area who participated in the study, we now have a baseline for that puzzle. Over time, we hope to expand our use of biomonitoring, both in terms of science and geography, to gain an even better understanding of how people’s indoor and outdoor environments are affecting their health.” 

Key findings of Biological Sampling
As with found with RTI’s air monitoring, blood and urine results from the study showed that PM2.5 exposure was not consistently altered by Indian River power plant operation. Blood samples were analyzed for volatile organic compounds and metals (cadmium, mercury, and lead). Volatile organic compounds and metals in blood samples were consistent across both sample years, 2011 and 2012.There were significant associations between blood mercury, blood lead, and urinary uranium and PM2.5, but all of the associations appeared to be driven by a single measurement from a single individual. 

Urine samples were analyzed for 14 metals. Data found that participants who consumed seafood within 48 hours of providing a urinary sample had increased urinary arsenic levels. Arsenic in fish is primarily an organic form of arsenic and it is nontoxic; this study measured total (inorganic and organic) arsenic in urine. While inorganic arsenic is considered toxic, organic arsenic is less toxic and is quickly excreted from the body. Arsenic concentrations in fish and shellfish from the nearby Inland Bays are not greater than concentrations in fish and shellfish from the entire East and Gulf Coasts of the U.S. Data from the biomonitoring study also suggests that the regular consumption of grains significantly decreases exposure to arsenic, reflecting possible dietary factors or food interactions.  

The study, the first of its kind in Delaware and the first funded by a state, was managed by the Delaware Cancer Consortium Environment Committee. The study was undertaken to establish a baseline for assessing human exposures to natural and synthetic compounds in the environment along the Indian River in the area of NRG’s power plant there. 

While information is expanding every day about the causes of cancer, research studies show mixed results in finding a direct link between cancer and the environment. Cancer incidence appears to be considerably impacted by lifestyle and genetics. To learn more about healthy lifestyle choices that may reduce risks for cancer, visit www.delawarecancerconsortium.org. To learn more about reducing potential toxins in your home, please visit http://www.dhss.delaware.gov/dhss/dph/hsp/hhdelres.html. The Millsboro Inhalation Exposure and Biomonitoring Study also can be found on the DNREC website.  

“Research shows that lifestyle improvements matter in reducing cancer risk,” said Dr. Karyl Rattay, Division of Public Health director. “An easy to remember healthy lifestyle slogan is ‘5-2-1 Almost None’: five or more fruits or vegetables daily, no more than two hours of recreational screen time, one hour of total physical activity a day and almost no sugary beverages. In addition to quitting smoking and limiting common toxins in the home, a healthier lifestyle can make a healthier you.”

The multimedia exposure study was underwritten by DNREC and the Delaware Cancer Consortium, in collaboration with the Delaware Health Fund. Jonathan Thornburg, PhD, and James Raymer, PhD, of RTI International were co-principal investigators. A registered Delaware Division of Public Health nurse collected the biological specimens, which were analyzed by the Delaware Public Health Laboratory while DNREC’s Division of Air Quality performed air dispersion modeling.
