“From the Raritan River to the Mullica River,

From the Delaware River to the Atlantic Ocean.”

2017:  
Sunday,  June 25, to Saturday July 1

Note:  The yard references are to my house in the section of Monroe between Helmetta and Jamesburg in South Middlesex County. My yard is in a Pine Barrens outlier on the Inner Coastal Plain, the soil is loamy, and my neighborhood is on the boundary of Gardening Zones 6b (cooler) and 7a (warmer). Afield references are to the Pine Barrens around Helmetta, unless otherwise noted. Notes and photographs are for the period covered, unless otherwise noted.

     PINE BARRENS AROUND HELMETTA:  Continuing flowering at Helmetta Pond were pickerel weed, “Pontederia cordata,” and fragrant water lilies, “Nymphaea odorata” Heads up on chiggers, family “Trombiculidae.” It may sound early, but I was scratching a little above my ankle and it felt like the beginning of a season of itchy chigger bites. Then, a local woodsman told me chiggers are indeed out. Avoid chigger bites by staying out of low brush. Another pest this time of year is the pine fly, genus “genus “Chrysops.”

     TURTLES:  I am still hearing a lot of talk about people coming across turtles, including misidentifying box turtles, “Terrapene carolina Carolina,” as water turtles. While a box turtle will go into water, it is generally a land turtle. So, if it is necessary to move a turtle for its safety, simply move it in the direction it is traveling. In recent days, Garden and Afield reader Bill McGovern came across two box turtles in his yard in Brick, Ocean County, and he reported, “Of course, I didn’t disturb the moment!” But he did supply a photograph of the mating turtles.

clip_image006Mating box turtles in Bill McGovern’s front yard in Brick, Ocean County. An easy way to identify the gender of box turtles is by their plastrons, or underside. A female’s is flat. A male’s is concave, so he can ride the female in mating, as shown in the photo.

     BLUEBERRIES:  Sophie Majka, a long-time neighbor of my family in the Pine Barrens around Helmetta, told me a little bit of local lore: Blueberries are ready to pick on St. John’s Day.

     Saturday, June 24, was St. John the Baptist Day. So, a few days later, I did a quick check of the woods and found a few berries — actually, probably black huckleberry, “Gaylussacia baccata.” A few ripened blue, most still green. Based on reports I have been seeing from the main Pine Barrens to the south, they have been ripe there for several days. The berries will be around for the upcoming weeks.

     Black huckleberry — along with low-shrub blueberries of the genus “Vaccinium” — are found on the uplands as the shrub understory of the forest. In the fall, these low-shrub berry plants are easy to identify because they turn flame red with the changing of “fall foliage” colors.

     For those more daring, head to the swamps for taller blueberry bushes of the genus “Vaccinium.”

     Just a note: Wild blueberries are not commercially cultivated berries, so they are smaller.

     A few years ago, Mrs. Majka and I spent some time up Jamesburg Park, picking the low-shrub blueberries. Mrs. Majka died at 92-years-old in March. This week, in the area where she and I picked, berries were ripening, providing a nice memory of Mrs. Majka.

     IN THE GARDEN:  I am harvesting carrots, but not to the extent I thought I would. Lettuce has taken on a bitter taste, so I stopped harvesting that. Cantaloupe and zinnia plants are flowering. Also watching tomato, cucumber, and sweet corn grow. Aside from harvesting carrots, I am back to the three Ws:  Weed, Water, and Wait.

clip_image010Zinnia, with which I hope to attract pollinators for the food plants, beginning to bloom in the garden.

     GARDENING KNOW-HOW:  I use various sources to learn about my food gardening:  my colleagues at the Rutgers University Cooperative Extension/Middlesex County Master Gardening program, other gardeners, farmers, farm-garden shows and articles. In her column this week in the Philadelpehia Inquirer newspaper, Sally McCabe talked about gardening deadlines associated with the Fourth of July, including it being the last time of the season to plant tomatoes. I had already planted tomato by seed and plant, but with the early lettuce done, I had gardening space to spare. After Sally’s column, I happened to be near one of my favorite gardening centers, Tony’s Farm and Garden Center in Windsor, Mercer County. At Tony’s, I picked up 12 plants in six varieties of Chef Jeff’s tomatoes. And following grandson Tony Ciaccio’s advice, I got them in the ground immediately.

clip_image012A last planting of tomatoes – various Chef Jeff’s brand – in the garden.

     WATERING THE GARDEN:  I water the garden daily, giving it a good soaking before 10 a.m. I either use hose-and-sprinkler, tapping house water, or I use a sprinkling can, using mostly rain, recycled cellar dehumidifier water, or recycled water from my sprinkling. When I use the hose-sprinkler system, I aim for 20 minutes; When I use the sprinkling can, I probably would use about 30 gallons to cover my entire garden of approximately 315 row-feet, or about 950 square feet. But, now, I am re-thinking this – Perhaps, I should go to a more soaking sprinkling, but fewer times a week. Thoughts?

     AROUND THE YARD:  Knock Out roses are starting to bloom for a second time this season.

clip_image014Rain clinging to a pitch pine, “Pinus rigida,” in my backyard.

     FEEDING BIRDS IN THE YARD:  This summer, I am trying something different – essentially not feeding birds, except with the finch feeder. I am keeping the finch feeder because I love the colorful males of the state bird, the eastern goldfinch, “Spinus tristis.” The idea of not feeding this summer is to let the birds enjoy my yard, with the three birdbaths I keep filled, and help me by eating insects. Birds, nature’s pesticide! Of course, not buying expensive bird seed saves money. However, I still have seed in a garbage pail in the garage. When I am home, I usually have the garage door open and, of course, the squirrels, “Sciurus carolinensis,” have discovered the garbage pail. Clang! That is the sound of the squirrels knocking something down as they open the garbage pail.

     PEDDIE LAKE:  Peddie Lake, created by the damming of Rocky Brook, is approximately 15 acres in Hightstown, Mercer County. Rocky Brook is a tributary of the Millstone River, part of the Raritan River-Bay watershed.

     SUNRISE/SUNSET:  For July 2, Sunday, to July 8, Saturday, the sun will rise at about 5:35 a.m. and set about 8:30 p.m.

     WEATHER:  The National Weather Service forecasting station for the area is at http://www.weather.gov/phi/.

     Joe Sapia, 60, is a lifelong Monroe resident. He is a Pine Barrens naturalist and an organic vegetable-fruit gardener.  He gardens the same backyard plot as did his Italian-American father, Joe Sr., and his Polish-immigrant, maternal grandmother, Annie Poznanski Onda. Both are inspirations for his food gardening. Joe is active with the Rutgers University Master Gardeners/Middlesex County program.
He draws inspiration on the Pine Barrens around Helmetta from his mother, Sophie Onda Sapia, who lived her whole life in these Pines, and his Grandma Annie.  Joe’s work also is at @JosephSapia on Twitter.com, along with Facebook.com on the Jersey Midlands page.

It’s Not Easy Being a Horseshoe Crab in New York Harbor

May 31, 2017

Intro by Alison M. Jones, NWNL Director: To honor last week’s Endangered Species Day, we’re posting Joe’s blog on horseshoe crabs which are “Near-Threatened” per Endangered Species International.

My children grew up on Long Island Sound mesmerized by the spring tide of these prehistoric, armored invertebrates. Since they’re now rarely seen on those shores, I couldn’t resist a bit of further research and adding some Editorial Notes!

Author and coastal naturalist Joe Reynolds is also an activist — and he can count. NWNL applauds his monitoring of these “upside-down skillets with tails.” I look forward to joining his next full-moon count in Raritan Bay! Check Joe’s blog with pictures, video and stories of wildlife from Sandy Hook Bay, Raritan Bay and Lower New York Bay: http://www.nyharbornature.com

WHAT’S HAPPENING UNDERFOOT?

Watch where you step this spring! Horseshoe crabs (Limulus polyphemus) are beginning to crawl ashore on beaches around Sandy Hook Bay, Raritan Bay, Jamaica Bay, and other shallow estuarine sites around New York Harbor. They mate on full and new moon evenings in May and June.

Yet another spawning season for horseshoe crabs has commenced, an annual rite of spring that goes back 450 million years. For Jurassic Park movie fans, that’s 230 million years before the first dinosaur! [Ed note: They even survived the Permian extinctions when 95% of all marine species disappeared.)

Known as “living fossils,” horseshoe crabs are harmless, ancient creatures effectively unchanged through time. Horseshoe crabs are more closely related to spiders and scorpions than to crabs. However, as marine arthropods, they are really a prehistoric family of animals unto themselves.

In late April, horseshoe crabs begin to migrate from deeper ocean waters into estuaries to breed. First on the beach are often males, waiting for available females. What follows is like a primitive singles bar, minus a colorful tiki bar. But alcohol isn’t needed here.

When a single female crab crawls out of the surf, she releases chemical cues called “pheromones” that help attract a breeding male. He then grasps her from behind with special appendages shaped like tiny boxing gloves on the end of his front walking legs. With her male in tow, she moves through the intertidal zone – a beach area that is above water at low tide and under water at high tide. There they deposit and fertilize 60,000 to 120,000 lime-green eggs in batches in wet sand.

In 2 to 4 weeks the eggs hatch. The size of a human fingernail, the young are a near–replica of an adult, though tail-less. The small crabs head straight to the water where they will grow in sandy shallow areas of the estuary. It takes 8 to 12 years for a crab to sexually mature and migrate back to bay beaches to breed.

 

THE VALUE OF HORSESHOE CRABS

Who would guess horseshoe crabs are critical to migratory shorebirds? But, yes, the fatty eggs of horseshoe crabs provide an important food source for many migratory shorebirds, including red knots (Calidris canutus), ruddy turnstones (Arenaria interpres), and sanderlings (Calidris alba), as they pause in their northward journeys to breed in the Arctic.

[ED Note: The red knot (part of the sandpiper family) makes one of the longest migrations of any bird: 15,000 km (9,300 mi) from Tierra del Fuego in S. America to the Arctic. On their mid-Atlantic stop, they re-energize and fatten up by feasting on what was a superabundant supply of horseshoe crab eggs. Red knots were numerous in N. America until masses were shot in the 1880’s. With further declines since the 1960’s, they are a “threatened species,” per the Endangered Species Act. So healthy horseshoe crab populations are critical to red knot survival. (Citation: http://www.audubon.org/field-guide/bird/red-knot)]

STEWARDS STUDYING THEIR DECLINE

Although the world’s largest spawning horseshoe crab populations are in Delaware Bay, the busy New York Harbor has crabs too. Few people welcome them; but those that do, know when and where to find them by the dozens, hundreds, or even thousands along the shore.

Our Bayshore Regional Watershed Council is an environmental group dedicated to improving water quality and restoring the wildlife habitat of Raritan Bay and Sandy Hook Bay. Since 2009, our volunteers have counted horseshoe crab populations along the southern shore of NY Harbor in Monmouth County, NJ. Our goal is to note their spawning population and ascertain if it is stable, increasing or decreasing.

So far our study shows a horseshoe crab population that is less than robust. There’s been a steady decline in adult females. In 2009, the Watershed Council counted 495 female crabs (singles and mating) across 1,000 feet of beach at five sites in Raritan and Sandy Hook Bays. Yet, in 2016 only 217 female crabs were counted at the same sites. (Ed: minus 50% in 7 years). The single female population decreased from 96 to 15 during this time period. (Ed: minus 85%)

Surprisingly, male populations are growing. In 2009, there were 679 male crabs at monitoring locations (single and mating) in Raritan and Sandy Hook Bays. This increased in 2016 to 1,016 (Ed: plus about 75%). The single males also increased: from 251 to 769 (Ed: plus 300%)

This great inequality between sexes affects their spawning. It takes two to make a baby! Swimming pairs (crabs seeking a place to lay eggs) decreased from 265 in 2009 to 130 in 2016 (Ed: minus 50% in 7 years). Burrowed pairs (crabs in the process of laying eggs) decreased from 276 to only 50 pairs in 2016. (Ed: minus 80%)

HUMAN OVER-HARVEST of HORSESHOE CRABS

What could cause such a dire decline in females? Humans and money, of course. Increased harvesting of horseshoe crabs in NY waters threatens their population. NY is the only state on the U.S. Atlantic Coast without a horseshoe-crab harvest moratorium during their breeding period.

Females are repeatedly harvested more than males since they are about 30% bigger and thus have more meat. Adult females also often carry eggs, which will make better bait.

Since 2009, NY State’s commercial quota for horseshoe crabs has been around 150,000 crabs. Some come from NJ’s Raritan Bay and the south shore of Long Island. But an undetermined amount of crabs in NY Harbor are being harvested illegally.

In 2013, two men from Brooklyn were arrested for stealing 200 horseshoe crabs from an island locally known as the Ruffle Bar in Jamaica Bay, Queens. They were charged with taking wildlife without a permit and disturbing wildlife breeding practices in a National Park.

On April 30, 2017, a woman was arrested in Jamaica Bay for illegally harvesting 7 horseshoe crabs. She told U.S. Park Police she was harvesting crabs for her business. The body parts of horseshoe crabs command a high price in some parts of the world since they are considered an aphrodisiac for men.

Horseshoe crabs are also used as bait for the American eel and channel whelk (aka conch) which are highly valued by Asians and Europeans. U.S. harvesters use body parts of female horseshoe crabs as bait for eel and whelk. Thus female horseshoe crabs are supplying global seafood needs. In 20 years, the price for 1 horseshoe crab has jumped from 25 cents to over $5.

Horseshoe crabs are also harvested by the medical industry for their copper-based blood which turns blue when exposed to air. Horseshoe crab blood has remarkable antibacterial properties that insure no impurities exist in medicines. The U.S. Food and Drug Administration (FDA) requires all intravenous drugs, vaccines and medical devices that come in contact with the human body (i.e., replacement hips, hearts, knees or pacemakers) to be tested by crab’s blood for bacterial toxins associated with toxic shock syndrome, meningitis and typhoid. Millions in the US survive each year due to the clotting characteristics of horseshoe crabs’ blue blood.

Unfortunately medical benefits for humans don’t benefit the crabs. Horseshoe crabs are to be caught; bled with about 30% of their blood taken; and then returned to waters where they were found. But according to author Alexis Madrigal, “Between 10 and 30 percent of the bled animals, according to varying estimates, actually die.” In addition, “bleeding a female horseshoe crab may make it less likely to mate, even if it doesn’t kill it.” (The Blood Harvest, The Atlantic, Feb 26, 2014)

Environmental scientists John Tanacredi and Sixto Portilla say many crabs taken from NY waters to be bled are often not returned to NY. Research on horseshoe crabs from Brooklyn to Montauk from 2003 to 2014 showed that numerous crabs harvested in NY and taken to MA to be bled were often released in local Cape Cod waters, not NY as required by permits. “Many of those animals are re-harvested for bait and sold back to NY fishermen at an average cost of $5/crab.” (Horseshoe Crab Biology, Conservation and Management, 2015)

IMPACTS OF HARVESTING HORSESHOE CRABS

It’s not an easy life in New York Harbor. The legal and illegal harvesting of horseshoe crabs, especially females, has limited their distribution and breeding, resulting in localized population declines. Horseshoe crabs could disappear locally if nothing is done to safeguard them in NY waters.

NJ instituted a moratorium on harvesting horseshoe crabs in 2007, but not NY where people can still harvest crabs. This puts the crab population under severe threat in the Lower New York, Raritan and Sandy Hook Bays.

YOU CAN HELP!  

Please email both Governor Cuomo (click here) and the NY State Department of Environmental Conservation (click here) to ask for greater protection of horseshoe crabs. NY State must restrict harvests in local waters, especially of female crabs. We need Albany to protect these prehistoric animals — before it’s too late.

Also, please share the plight of horseshoe crabs with friends and family. The more who are aware of the threat to horseshoe crabs, the more likely we can ensure their survival in the Raritan, Sandy Hook and Jamaica Bays.

If greater awareness and public support is coupled with greater conservation efforts, then these Ancient Mariners of New York Harbor can fill the beaches for many spring seasons to come. Let’s make sure they endure for another 450 million years!

“Living Shorelines” Can Fortify Our Coastlines … A Solution at Work in New Jersey’s Raritan Bay

November 29, 2016

By Meredith Comi, Restoration Program Director of the NY/NJ Baykeeper 

After Hurricane Sandy, it was clear that coastal resiliency had become an immediate priority. Thus, Baykeeper began an innovative project to determine if a “Living Shoreline” of oysters could stabilize eroding shorelines of the urban New York-New Jersey Harbor Estuary. Perhaps they would simultaneously protect the surrounding environment, improve water quality, and create healthy aquatic habitats.

Oysters are powerful. They can filter and clean water, a much-needed service today. They can provide reef habitat for other sea creatures and improve resiliency to storm surge and erosion. Oysters once thrived in the NY-NJ Harbor Estuary — so much so that Ellis Island was previously called Little Oyster Island.  However, over-harvesting, pollution and the sedimentation of reefs resulted in a sharp population decline. Today there is no longer a sustainable oyster population in the NY-NJ Harbor area; but NY/NJ Baykeeper is working to restore them. As a bi-state restoration leader, NY/NJ Baykeeper has had restoration projects in both NJ and NY waters.

In mid-August, 2016, NY/NJ Baykeeper and its partners installed a first-of-its-kind urban “Living Shoreline” in northern New Jersey waters.  Located in the Raritan Bay at the Naval Weapons Station Earle in Monmouth County, a new 0.91 acre Living Shoreline consists of an artificial reef, using live oysters. Known as “oyster castles,” these new concrete structures are meant to provide the needed hard surface on which oysters can attach and grow. These 137 castles with about 10,000 oyster larvae can thus begin to fortify and protect the Raritan Bayshore.

In 2010 the NJ Department of Environmental Protection banned all shellfish research, restoration and education activities in waters (1) deemed too contaminated or (2) “Restricted” or “Prohibited” for shellfish harvest.  Thus earlier oyster reef projects in nearby Navesink River and Keyport Harbor had to be moved. At that point, the U.S. Navy and NY/NJ Baykeeper became “Living Shoreline” partners. The U.S. Navy at Naval Weapons Station Earle, with its non-accessible stretch of shoreline, provides protected property, guidance and valuable support for Baykeeper’s oyster restoration activities.

Additional restoration activities at Naval Weapons Station Earle include setting oysters at NY/NJ Baykeeper’s aquaculture facility near the mouth of Ware Creek, and monitoring the oysters and structures in the ¼-acre experimental restoration plot to assess survival and growth.

Deployment.jpg

Deposition of “oyster castles” into the Raritan Bay at NWS Earle.

NY/NJ Baykeeper has monitored this Living Shoreline twice since its August installation, finding that the oysters grew 22mm in just 2 months!  Other organisms like sponges and algae are attached to the castles as well, further contributing to the Living Shoreline habitat.  All the castles have stayed in place, even during the rough seas when Hurricane Hermine was off shore. This is a good sign of how the castles will hold up in the dynamic Raritan Bay.

This winter, oyster growth will become slower as the water becomes cooler. Since all the oysters are far enough under the water’s surface, they will be protected should the Bay freeze over. Come spring, this Living Shoreline will be expanded, adding more castles and oysters to the system.  Meanwhile, NY/NJ Baykeeper continues its study of biodiversity  and its collection of water quality data.
