Like all ecosystems, Delaware Bay is amazingly complex, and there’s no one way to fix it. Between climate change, sea level rise, and the growing risk of major storms, there’s a lot to consider.
We’ve learned that restoring healthy marsh habitat is a key component in rebuilding Delaware Bay beaches; however, we’re also trying to further strengthen bayshore beaches by building reefs – living underwater infrastructure. By creating some reef structures we can keep the sand where we’re putting it.
A new episode of our video series “New Jersey’s Hidden Coast” will air every two weeks throughout the summer! Catch a glimpse of the bay, the horseshoe crab at the center of the bay’s system, and the incredible relationship between horseshoe crabs and migratory birds, like the red knot. We will reveal the real value of horseshoe crabs, the challenges to the ecosystem, and the potential for a thriving regional economy along the Bayshore. We will show Hurricane Sandy as a catalyst for decisive action and the work being done to rebuild the area for both people and wildlife.
Over the next several weeks, we will explore the use of “living shorelines” instead of bulkheads and the central importance of marshes to the marine ecosystem. We will discover the on-the-ground, grassroots efforts of the community to build oyster reefs alongside veterans. And we will examine the future of the Bay and the work that needs to be done to preserve our conservation successes thus far.

Periodic storms are an unavoidable fact of life when you live along the coast. In rebuilding after Hurricane Sandy, we realized we needed a new way of thinking about beach restoration on New Jersey’s Hidden Coast – the Delaware Bayshore. Storms like Sandy and Katrina have shown us that the most effective way to control storm surge is to follow Mother Nature’s lead. The restoration of tidal wetlands, or marshes, will help absorb the brunt of coastal storms, acting as a buffer between the beaches and the mainland.
Learn more about marsh restoration – one of the key components to rebuilding coastal beaches – in the fourth episode of our video series.

Did you know that wetlands are very important habitats that provide benefits for both humans and wildlife alike? Generally defined as “land consisting of marshes or swamps”, wetlands provide natural flood control by soaking up runoff from heavy rains and filter out chemicals, pollutants, and sediments that would otherwise contaminate our drinking water. They also provide a home for much of the fish and wildlife species that inhabit the state of New Jersey.
Due to the extensive development and urbanization of the state to accommodate our ever-growing population, much of New Jersey’s natural wetlands have ceased to exist. In the 1980’s a study conducted by the United States Fish and Wildlife Service (USFWS) found that, since the mid-1900’s, the state lost at least 20 percent of its natural wetland resources. Since then, concerted efforts have been made to protect, restore, and create wetland habitats across the state. One such effort has been made by the Natural Resource Conservation Service (NRCS) with the Wetland Reserve Easement (WRE) project, a component of The Agricultural Conservation Program in partnership with Conserve Wildlife Foundation. WRE is a voluntary program that provides an opportunity for landowners to receive financial assistance in exchange for permanently protecting retired agricultural land.
Lamington River, Bedminster, Somerset County. Location of American toads.
While walking one such easement property in Bedminster, Somerset County we observed a population of American Toad (Anaxyrus americanus) polliwogs in a shallow water inlet along the Lamington River. There had to be hundreds of these young toads both in the water and on the shore. The American toad is just one example of a wildlife species that benefits from readily available wetland habitat and that is also vulnerable to habitat loss due to wetland destruction. Although they are very common in New Jersey, and many people can recognize a toad when they see one, there are still a handful of myths and misconceptions about toads that I would like to address.

Myth 1 – Toads will give you warts if you touch them: False. While toads do have warts across their bodies, they cannot transmit these warts to humans as warts in people are actually caused by a virus. This doesn’t mean you should go around handling every toad you come across, but if you do pick one up you will not contract warts from it.
Myth 2 – Toads must be completely safe to handle if they do not transmit warts: False. Toads secrete toxins through their skin so it is completely necessary to wash one’s hands after handling a toad. They also are known to pee in self-defense, especially when picked up by a human. This may not bother some people but you should still make sure to wash your hands after holding one.
Myth 3 – Wild-caught toads make good pets: False. While toads are very easy to care for, and it is not hard to replicate their natural environment in a fish tank, it is still very important to leave wild toads wherever you find them. Toads will spend their whole lives in one area, leaving it once or twice a year just to go breed, and it can be very disruptive to a toad’s well-being to find itself in a new home. If you do happen to keep a toad for more than a few minutes, it is of utmost importance that it gets returned to exactly where you found it. Releasing it into any suitable habitat would seem adequate enough, but it would be like if one day you just found yourself wandering around Nebraska with no way of knowing where to go or how to get home!
Myth 4 – Toads are terrestrial species and do not need to be near water to thrive: False. Toads will spend most of their lives hanging out in fields or meadows or even forests, but they do need access to pools of water in order to breed. Every summer, toads will migrate to pools to find mates and to lay eggs. While they do not swim, like their close relative the frog, they still benefit from having shallow water habitat in close proximity to where they spend most of their time.
Myth 5 – Toads are poisonous: TRUE. Contact with a toad’s skin will not give you warts and it will not poison you just through skin-to-skin contact. However, they have glands just behind their eyes that when pressed will secrete a milky-white substance that can severely harm someone if ingested. This may not be a danger to most people, as most humans have no interest in putting toads in their mouths, but it is a concern for dogs. Dogs very typically love to grab strange objects with their mouths, which applies enough pressure to a toad’s glands to excrete their poison. This can be very detrimental to a canine’s health and can even kill them. If you find yourself wandering around toad habitats with your beloved pup ensure that they do not try to eat any toads that they come across. If your dog does mistakenly poison itself you should take it to a vet immediately.

Through programs like WRE, more and more wetland habitats are being made available across the state for wildlife species like toads. It is important to be aware of what impact you can have on them, as well as what could happen to you or your pet through contact with toads.
At 8:00 PM on October 29th, 2012, Hurricane Sandy made landfall in Brigantine, New Jersey, only about 30 miles from New Jersey’s Hidden Coast – the Delaware Bayshore. The storm was devastating for the people of the area, many of whom lost their homes and livelihoods. It was equally hard on the area’s wildlife, bringing many species, including the famous horseshoe crab and red knot, perilously close to extinction.

Technology has proven to be vital to Conserve Wildlife Foundation’s work protecting rare wildlife species over the years. Our biologists depend greatly on modern technologies to band, track, and share online the journeys of wildlife. Our webcams broadcast the most intimate behaviors of nesting birds and bats across the web. And we seek out ever-evolving communications technologies to spread the word about the inspiring stories of wildlife, from social media and infographs to e-books and Story Maps. These technologies offer newfound abilities to share complex data on multiple levels, while still incorporating the awe-inspiring photography and videos that bring wildlife’s stories to life.
Conserve Wildlife Foundation of New Jersey is excited to offer our 2015 Annual Report in a unique format that utilizes one of those technologies – Story Maps. In the past year, we have explored the lives of seals, eagles, and freshwater mussels with Story Maps – and the annual report allows all of our projects to be highlighted in this interactive format as well.
Visit the multiple pages within this Story Map to learn about Conserve Wildlife Foundation’s many projects and partnerships in 2015, and the imperiled wildlife species in need of our help. Find examples of the innovative and dedicated leadership of our biologists and volunteers. And take an online journey across the state to learn how our projects made a difference in all corners of New Jersey in 2015 – a great year for wildlife in the Garden State!
Horseshoe crabs may be one of the most unusual animals in the world, but they’re also one of the most extraordinary. They’ve been around for hundreds of millions of years, and we’re only now starting to understand just how important they are – not just to the natural world, but also to the world of medicine. Discover the real value of horseshoe crabs, found throughout New Jersey’s Hidden Coast – the Delaware Bayshore.

NJDEP’s Barnegat Bay Blitz to Take Place Friday, June 3, 2016
by Lindsay McNamara, Communications Manager
Concerned about the health of the Barnegat Bay ecosystem? Consider participating in a day of action for the Bay! The New Jersey Department of Environmental Protection (DEP) will be hosting its next Barnegat Bay Blitz clean-up day on Friday, June 3.
You can join thousands of volunteers as they fan out across the watershed, which includes all of Ocean County amd parts of Monmouth County, to clean up the Barnegat Bay Watershed and spread awareness about the people pollution impacting the Bay. Clean-up events are happening watershed-wide!
In the middle of Barnegat Bay, there are many small islands called Sedges. These islands are home to a number of species of plants and animals, but unfortunately are impacted by litter that the tide washes in. Volunteers by boat, kayak and standup paddle board will make their way out to many of these islands, including Island Beach State Park, Seaside Heights and Brick to sweep them clean of debris. Get involved!
It’s not just the bayfront communities that impact Barnegat Bay. Communities miles and miles inland also play a role. After all, we are all downstream! That is why at the Barnegat Bay Blitz, volunteers will work to clean up all over the watershed, from inland areas of Plumsted to the barrier islands. In Plumsted, a farming community, volunteers include more than just people! Llamas will also join the crew to help haul out trash and debris that volunteers collect from the Colliers Mills Wildlife Management area. To make friends with llamas, register for the Plumsted clean-up on DEP’s website.
We hope to see you tomorrow, Friday, June 3, for DEP’s next Barnegat Bay Blitz! Here are some of our favorite photos from last year’s event:
Coalition of Agencies Working Together to Enhance Turtle Habitat in Sussex County

Through federal partnerships and incentive programs, the federally endangered bog turtle can have a fighting chance in New Jersey! The U.S. Department of Agriculture’s Natural Resource Conservation Service (NRCS) and the U.S. Fish and Wildlife Service (USFWS), in partnership with Conserve Wildlife Foundation, New Jersey Audubon Society, and Wallkill River Watershed Management Group, are currently working to restore a once natural wetland on private property in Sussex County. The program is possible through the Agricultural Conservation Easement Program, Wetlands Reserve Easement (WRE). WRE is a voluntary program that provides an opportunity for landowners to receive financial assistance in exchange for permanently protecting retired agricultural land. In their first year, NRCS and USFWS helped to restore and protect 52 acres of bog turtle habitat in New Jersey!
The goal of this project is to restore hydrology, enhance bog turtle habitat, control invasive species, and stabilize the stream bank. Through the partnerships we have already planted riparian buffers along the river and plan to conduct invasive species removal and create shallow water pools for wildlife such as amphibians.
The site contains active bog turtle habitat that has been degraded over time through grazing and other human induced impacts. Bog turtles are found throughout the state, but Sussex County is a hot spot because of its prime wetlands habitat. At the bog turtle site, cattle will be actively managed to graze the area for specific periods of time throughout the year. This will reduce invasive species and create mucky soils preferred by the bog turtle.
New Jersey Audubon Society was also able to supply a native sedge plant to enhance the wetland. Last week, a youth corps group from Phillipsburg, New Jersey met on site to help plant green bulrush. The bulrush will aid to improve water quality, as it will take up phosphorous and other nutrients moving into the water column. It will also aid to reduce erosion and provide food and cover for ducks, and other water birds. So far, 5,050 plugs of green bulrush have been planted!
CWF has also partnered on other Sussex County bog turtle restoration projects with the New Jersey Division of Fish and Wildlife’s Endangered and Nongame Species Program, National Fish and Wildlife Foundation, USFWS, and the New Jersey Corporate Wetlands Restoration Program.

One of a Series of Updates on the 20th Year of the Delaware Bay Shorebird Project
by Dr. Larry Niles, LJ Niles Associates LLC
In spite of the very spotty horseshoe crab spawn, the shorebirds on Delaware Bay seem to be gaining weight on schedule. Below you will find a graph composed of the average weights of all the red knots by our team for the last 20 years. The curve is the result of combining all the data we collected and shows the sweet spot for most knots. As they arrive, they take time to gain weight but after about 5 days they start gaining weight rapidly. After the 26th or so, birds start reaching the critical weights necessary to safely reach the Arctic breeding grounds. One can see the curve deep at the end of the month because fat birds fly off leaving the less fat behind. In general, weights above the line are good, below the line not good. The large squares on the graph are the average weight of this year. So far, so good.

This is a bit of a surprise for the team. The weather here on Delaware Bay is wet and cold. The water temperature struggles to lift above 59 degrees, the temperature necessary for a crab to spawn on Delaware Bay. So far, the temperature has been below 59 degrees more than above. We had good spawns in the last few days, but only in key places.
Water temperature at the mouth of Delaware Bay.
A key place for horseshoe crab spawn happens to be the mouths of small creeks. The New Jersey side of Delaware Bay is blessed with many small intertidal creeks, most draining only marsh or small inland watersheds. Some of these creeks have names, Goshen Creek, West Creek, Nantuxent Creek, but many do not. Almost all have shoals at their mouth with the bay because bay currents, tidal flow and wind driven waves act against each other to settle sand coming from adjacent beaches or from inside the creek drainage. Much of the sand lost from our restored beaches settles into these shoals. For horseshoe crabs, these shoals are sweet places.

At the time of this picture, over 3,000 knots and 1,000 ruddy turnstones were using the shoal and the inner sandy beach behind the shoal. Photo by Stephanie Feigin.Red Knots in flight on Cooks Shoal.

Usually, the shoals lie just under the high tide line and are composed of large grain sand, the optimal conditions for a good crab spawn. However, the most important characteristic and key to this unusually cold May, is the warming water flowing out from the marsh drainages. On a flooding tide, colder warmer flows into the vast marshes of the Delaware Bay. This warms the water. On an ebbing tide, it flows out the creek and over the shoals, making them slightly warmer and more conducive to inducing crabs to spawn. Even on these cold days, they literally climb over themselves to breed on the shoals. The shoals also protect the inner mouths of the creeks thus making the sandy shores at the mouth of the creek a crab spawning heaven.

However, as it seems usual with this blog, there is a growing concern. Right now, most of the red knot population on the bay is feeding on these shoals along with thousands of other species, but only half have arrived from southern wintering areas. We now have about 12,000 red knots on the bay and in a day or two we should find another 12,000 falling from the sky. Will there be enough eggs? Will the water temperature finally reach normal levels? These are the important question for the next few days.
