Preservation of declining habitat is key to survival of high marsh wildlife

As the sea rises, high areas on the coastal salt marsh will decline or disappear. These areas are higher in elevation and usually consist of more sandy soil. The sandy soil attracts nesting female diamondback terrapins, like many roadsides throughout New Jersey. As we harden shorelines to hold back floodwaters, terrapins will face more dangerous treks to find suitable nesting habitat, unless these high marsh areas are enhanced and elevations raised. For the past five years we have been surveying Route 30 (Whitehorse Pike) during summer months for the occurance of terrapins on the highway. Adult female terrapins enter the roadway while seeking these sandy areas above the high tide line. Most, if not all, do not survive crossing Route 30.

ACTION ALERT: Support ecological management of the most valuable public resource for our coastal ecosystem and economy

The Atlantic States Marine Fisheries Commission is accepting public comment on the establishment of ecological management of Atlantic menhaden (Brevoortia tyrannus), which is a keystone species. Basically, a keystone species is one that plays a large role in the ecosystem where it lives. If a keystone species is lost then the ecosystem would dramatically change or cease to function, causing widespread effects to other species that benefit. In New Jersey, ospreyshave largely benefited from a healthy menhaden population as we’ve had relatively high reproductive rates (more than double what’s needed to sustain population) over the past decade. From 2006 to 2016, the population has grown by 30% and above the pre-DDT, historic milestone of over 500 nesting pairs. Around 82% of the state population of ospreys nests along the Atlantic Coast and we observe menhaden at a huge number of nests during our mid-summer surveys. If menhaden numbers drop, then we will likely see osprey numbers follow suite, as reproductive rates will decline, as they are in the Chesapeake Bay.
Anyone who has monitored or closely followed piping plovers knows these (pictured) tracks well. They have to. Most wildlife leaves behind distinct clues that reveal their presence, but if you are tracking the well camouflaged piping plover, the best, and sometimes only, clue you have are these ephemeral tracks in the sand.
Finding these tracks, especially the first ones of the breeding season in early spring, makes my heart stir, even after 20+ years of searching for piping plovers. They shout, “I’m here, now find me”. These particular tracks happen to be a late season find, sighted just this past week, special in a different way as they were unexpected and may be my last glimpse of them here in New Jersey this year as most piping plovers have now migrated south for the winter. I followed the tracks like I always do and soon enough I spotted three pale beauties resting absolutely still on a nearby sand hummock.
This blog doesn’t contain any earth-shattering conservation message. It is just about my own love affair with piping plovers. I am lucky to have found that magical something in nature that moves me. I hope each of you has your own version, whether it be a delicate monarch butterfly improbably fluttering thousands of miles in the wind towards its wintering grounds in Mexico or a powerful bison lumbering across a grasslands vista out west. One of the main reasons my colleagues and I are engaged in conservation work is so everyone has the opportunity to experience and be inspired by wildlife in its natural habitats.
Piping plovers will not provide a cure for cancer, they will not boost our economy, and they certainly will not be the key to uniting us politically. They will bring a smile to your face, they will evoke wonder, and they may just make your day. Sometimes that is enough.
We keep track of all re-sightings we receive of NJ (green) banded eagles. This information is important as it lets us know where eagles raised in NJ go after leaving the nest and eventually where they end up nesting. In 2017 we have had NJ banded birds sighted in NJ as well as PA and VT.
On April 15, 2017 Mary Dunham photographed NJ banded D/18 near Lake Como in Belmar, NJ. The female was banded in March 2011 at the Manasquan Reservoir, Monmouth County. She was with another smaller adult, assumed to be a male. While Mary watched a third adult eagle came into the area and the pair chased it away. This is an indicator that D/18 was paired up and perhaps was nesting in the area.

In August we received a report that D/18 was sighted once again. This time she was up near the NY- Canada border. We don’t know much about the movements of nesting eagles so we can only speculate why she made such a big move north. Perhaps she went north with a recent fledgling or maybe she was kicked out of the pair by an intruder eagle and headed north?
D/40@ Reid Hoffer
In March we were contacted by Reid Hoffer who monitors an eagle nest along a reservoir in Rockland County NY. He was able to get a photo of a green band, D/40, she was banded May 2011 at Newton Reservoir in Sussex County. Mr. Hoffer reports that unfortunately the pair did not produce any offspring this year.

Telemetry
We are also currently tracking three NJ eagle with transmitters attached. The New Jersey Bald Eagle Tracking project shows the movements of all three of these birds as well as their history.
Two of the transmittered birds fledged from Merrill Creek Reservoir in Warren County, NJ. Harmony 2, has spent the last four years in a 100-mile swath of western Connecticut and Massachusetts. She fledged in 2012 making her a 5th year bird and breeding age. We suspect she’ll nest in the same area next season. Haliae fledged in 2013 and has spent the past three years mostly around the Eastern Shore of Maryland. Perhaps she’ll stay in that area to nest? So two birds from the same nest, but one has settled to the north and one to the south.
Nacote, a male from the Galloway nest in Atlantic County, has stayed more “local” to his home area. He’s spent the last three seasons in Atlantic, Cumberland and Cape May Counties. He favors the CMC landfill and local sand pits where other eagles are known to roost and feed.
All this information helps us to locate roost and foraging areas and protect them. It’s also fascinating to know where NJ eagles go after leaving their nest area, especially when they begin nesting. Why do some head north, others south and yet others stay near their “home” range? We don’t know, and that’s ok, it’s what makes them wild!
In this blog series, my goal is to examine the importance of grassland habitat in our state, introduce CWF’s new habitat restoration project, and highlight many of the species of grassland birds our project aims to benefit. So, first I’ll start off with a little background information about grasslands and why we need to preserve, restore and create more of this critical habitat.

Hundreds of high school students from across the state competed in Conserve Wildlife Foundation’s “Species on the Edge 2.0 Multimedia Contest”, engaging more than 23,000 people on social media with messages of wildlife protection. Of the entrants, three select winners earned scholarship funds.
“Today’s high schoolers grow up with an inherent expertise with technology and multimedia, yet it is far too easy for them to grow disconnected from the stunning nature and wildlife all around us. This contest utilizes their talents for technology to engage thousands of people across New Jersey and beyond with the wonders of wildlife – and a reminder for all of us to balance our lives by getting outdoors as well as online,” said David Wheeler, Executive Director of the nonprofit Conserve Wildlife Foundation.
Thanks to the generosity of corporate sponsor PSEG, Conserve Wildlife Foundation’s third annual multimedia contest focused on social media, giving students the opportunity to submit an original social media campaign showing why wildlife is important to protect and preserve in New Jersey and beyond. Winners were recognized this summer at a ceremony at PSE&G headquarters in Newark.
In addition to the student winners, CWF recognized Claire Ang, a marine science teacher from the Marine Academy for Science and Technology. Ms. Ang’s exceptional leadership engaged her high school in the contest, raising awareness about species protection.
Fifteen-year old Ethan Chang from Woodbridge High School won first place, while second and third place winners were Caitlyn Drace from Woodbridge High School and Olivia Gemarro from the Marine Academy of Science and Technology. In addition, Sarina Schmidt of Manchester Township High School and Nina Colagiovanni of Point Pleasant Beach High School were recognized for their wildlife videos. Each of the honorees plan to pursue wildlife conservation in various ways.
All three winners were awarded a gift bag, scholarships, and a special invitation to an eco-tour at Sedge Islands. Off the coast of Barnegat Bay, winners will have the unique opportunity to spend the day fishing, clamming, and wildlife watching.
Director of Education Stephanie DAlessio said, “The Species on the Edge 2.0 contest capitalizes on high school students’ expertise with social media platforms and provides them with the opportunity to showcase their talents, creativity, and their love for nature. This year’s contest allows high school students to advocate for wildlife conservation and to help raise awareness on social media about the importance of preserving and protecting wildlife.”
PSEG’s commitment to environmental stewardship made the contest possible by supporting funding for the scholarships. PSEG is a leader in conservation and restoration projects, including efforts to increase numbers of pollinators in the state.

I would like to take the time to share a noteworthy event from last week, as well as highlight a CWF volunteer who deserves recognition for his dedication to wildlife. CWF received a call last Friday from a concerned citizen about an osprey chick that had fallen from its nest in Avalon. Osprey chicks are extremely vulnerable to summer storms, and are often blown right from their nests in strong winds. The storm that pushed through the area Thursday night had likely blown this chick out of its nest onto the marsh below. This particular nest had just been surveyed on July 6 and had contained three young chicks.

Often when staff members are not available to respond to calls like this, we rely on our volunteers to represent us. In this case, when CWF volunteer John King got the call, he hooked up his boat and immediately headed out to assess the situation in hopes of making a rescue. When he arrived on the scene, John realized that there were actually three osprey chicks on the ground below the nest; however, two of them were unfortunately already deceased. The parents were also sitting on the ground with the one surviving chick when he arrived. John picked up the chick and examined it for injuries. When he determined it was in good condition, he carried it up a ladder and placed it back into the nest as the parents circled and screamed above him. As he left the site, the parents immediately returned to the nest to check on their chick.

Even though John was only able to save one of the three chicks, this was still a success story that would not have been possible without the help of a devoted volunteer. The concerned citizens who had called in the emergency watched the whole rescue from across the lagoon and reported back the following day that the chick was sitting up in the nest looking healthy. CWF also greatly appreciates citizens who care enough to observe wildlife responsibly and report wildlife emergencies when necessary.

John King has been volunteering for CWF for many years and has worked on several projects including the Calling Amphibian Project, NJ Tiger Salamander project and the NJ eagle project. He has been very involved with the NJ osprey project, headed by CWF’s Ben Wurst, assisting with osprey surveys during the breeding season and helping to construct and erect nest platforms over the winter. In addition to CWF, John also volunteers with many other conservation organizations and is always happy to lend a hand. Although he is retired, his volunteer work is practically a full time job. I sincerely admire John’s continued enthusiasm and his dedication to wildlife, and I believe the world would be a better place if there were more people like him.
Conserve Wildlife Foundation of NJ thanks you, John!
Citizen Scientists Needed to help collect data on nesting ospreys
by Ben Wurst, Habitat Program Manager
Two young ospreys and an adult on a nest in Ocean County.
This year we are hoping to get a better estimate of the size and health of the osprey population in New Jersey. Up from only 50 pairs in the early 1970s to an estimated 600+ pairs today. Ospreys are an indicator species and as top tier predators, they show the effects of contaminants in the environment before many other long lived species. They are our new age “canary in the coal mine” so keeping tabs on the health of their population is key to assessing the health of our estuarine and marine ecosystems.
