SEVERAL SPECIES OF FRESHWATER FISH TO RECEIVE IMPERILED STATUS
By Michael Davenport, GIS Program Manager
The New Jersey Division of Fish and Wildlife has recently completed a status review of the freshwater fish species within the state. A total of 53 species were reviewed by a panel of experts and the results of that review were then presented to the Endangered and Nongame Advisory Committee which voted on March 16th to recommend the status changes. As a result of this status review, ten additional species within the state will be receiving an imperiled status of either Endangered, Threatened, or Special Concern. The date for when those listings will become official is still unknown.
Conserve Wildlife Foundation of NJ’s online field guide, a one-of-a-kind free reference focused on New Jersey’s wildlife, has expanded to include the additional fish species.

HOW A SPECIES BECOMES LISTED AS “ENDANGERED” IN NEW JERSEY
By Michael Davenport, GIS Program Manager
How does the state’s Endangered and Nongame Species Program (ENSP) determine whether a species is imperiled or secure within the state? The process for determining a species’ state status is known as the “Delphi” method of species status review and it is a process which Conserve Wildlife Foundation of NJ (CWF) staff assists the state with.

The ENSP endeavors to complete a review of all species currently included on the Endangered and Nongame lists every 5-10 years. In addition, other species groups not currently included on those lists may be reviewed for status as well. At any given time, there may be several status reviews being conducted.
The first step taken in conducting a status review is to identify experts and invite them to participate as a member of a review panel. Members of the panel may be comprised of experts within academia, government agencies, non-profits, or private consultants as well as others.
Once a sufficient number of experts have agreed to participate, staff within the ENSP and CWF will compile background material for the species being reviewed. This may include reports, survey data, and data contained within the state’s Biotics database which is the electronic warehouse for all imperiled species data in New Jersey. This background data, as well as a list of the species being reviewed, and definitions of the status options, are then sent to the panelists for Round 1 of the review.
Delphi reviews are comprised of multiple “Rounds”. For each round, each panelist will choose a status for each species based upon that panelist’s expertise as well as the background material. The panelist then sends their selections and justification regarding each species to ENSP or CWF staff who compile the results submitted by all panelists. The review is completed anonymously, so the panelists do not know the identities of the other participants.
For each species, the panel must reach consensus of at least 85% of the respondents for a species’ status to be determined. If consensus is not reached during the first round, then that species will move on to be reviewed in Round 2. For each new round, the panelists’ status choices during the prior round, as well as all the comments made, are available to the panel, so that reviewers can consider the weight of evidence and other reviewers’ opinions on status as they prepare to vote again. This continues until consensus is reached for all species under review.
Once consensus is reached for all species or, if after four rounds have passed and consensus could not be reached for some species, ENSP or CWF staff will take the compiled Delphi results to the Endangered and Nongame Species Advisory Committee (ENSAC). ENSAC reviews the results and makes the final recommendations on status for those species for which consensus was not reached by the expert panel. Based upon ENSAC’s recommendations, any changes to the Endangered and Nongame lists must go through a formal rule-making process before those changes can be made official.
The Delphi review process is a science-based, anonymous review by those with the most expertise on the species within New Jersey. A great deal of thought and time go into preparing for and carrying out a review and CWF has played a major role in assisting with the process. From the blue whale to fairy shrimp, each species will ultimately receive a state status, leading the way for conservation action.
The following are state conservation status categories; the last, “Not Applicable”, is used only during the status review and is not a legal status category.
Endangered
Applies to species whose prospects for survival within the state are in immediate danger due to one or several factors, such as loss or degradation of habitat, overexploitation, predation, competition, disease or environmental pollution, etc. An Endangered species likely requires immediate action to avoid extinction within New Jersey.
Threatened
Applies to species that may become Endangered if conditions surrounding it begin to or continue to deteriorate. Thus, a Threatened species is one that is already vulnerable as a result of small population size, restricted range, narrow habitat affinities, significant population decline, etc.
Special Concern
Applies to species that warrant special attention because of inherent vulnerability to environmental deterioration or habitat modification that would result in their becoming Threatened. This category would also be applied to species that meet the forgoing criteria and for which there is little understanding of their current population status in the state.
Secure/Stable
Applies to species that appear to be secure in New Jersey and not in danger of falling into any of the preceding three categories in the near future.
Undetermined/Unknown
Applies to a species that cannot be assigned a status of endangered, threatened, special concern or secure/stable because not enough information exists on which to base a judgment.
Not Applicable
Applies to species that do not occur in New Jersey, including occasional non-breeding strays and transient breeders that fail to persist.
23 WILDLIFE SPECIES ADDED TO CWF’S ONLINE FIELD GUIDE
By Michael Davenport, GIS Program Manager
Conserve Wildlife Foundation of NJ’s online field guide, a one-of-a-kind free reference focused on New Jersey’s wildlife, has recently expanded to include 23 additional species. As a result of recent status reviews by the state’s Endangered and Nongame Species Program for reptiles, amphibians, and butterflies, additional species within the state will be receiving an imperiled status of either Endangered, Threatened, or Special Concern. Six reptile species are being added as well as four amphibians and thirteen butterfly species.

Later this week, two additional blog entries will be posted regarding the status review process and the new listings. The posts will be: “Species Status Review process” (WEDNESDAY); and “How you can help fill-in data gaps” (FRIDAY).
The list of “new” species is below and each species name links to its field guide entry on our website:
Conserve Wildlife Foundation of New Jersey today released the 2015 Bald Eagle Report, highlighting the number of nesting pairs, active nests and nest productivity for the raptors throughout New Jersey with data collected by New Jersey Department of Environmental Protection Division of Fish and Wildlife biologists, CWF biologists and committed volunteers.
“With 161 pairs of bald eagles this past year — up from just a single nest in the early 1980’s — the dramatic ongoing recovery of bald eagles across the northeast continues to inspire so many of us,” said David Wheeler, Conserve Wildlife Foundation Executive Director. “The thrill of seeing a bald eagle fly across the sky is unparalleled. This report captures how these eagles are continuing their All-American return.”
The report notes that thirteen new eagle pairs were found this season, nine in the south, two in Central Jersey and two in Northern New Jersey.
With a wingspan of six to seven feet, bald eagles are larger than most birds. The bald eagle is restricted to North America and is usually found within close proximity to open water. In New Jersey, bald eagles reside year-round, usually remaining in the area surrounding their nest. They begin courtship and nest building in late December and January, adding to their existing nest. Over time, some nests can reach 10 feet across and weigh up to 2,000 pounds.
Conserve Wildlife Foundation partners with Duke Farms on a webcam that provides a live look at a bald eagle nest in Hillsborough, New Jersey. This spring, the EagleCam will allow viewers an up close and personal view into the lives of a pair of bald eagles as they breed, incubate, and raise young. Between the general public and classrooms up and down the east coast, the EagleCamhas many fans – over 10 million viewers and growing!
The federal government removed the bald eagle from its list of Endangered Species in August of 2007, but the bald eagle’s official New Jersey status remains state-endangered for the breeding season and state-threatened for the non-breeding season.
“One of our encouraging findings is that the population of wintering bald eagles has grown along with the nesting population over the past decade,” said Conserve Wildlife Foundation eagle biologist Larissa Smith. “This growth reflects the increasing populations in New Jersey and across the northeast, as recovery efforts continue to pay off for eagles. In addition to our fellow scientists in New Jersey and nearby states, I’d like to thank the wonderful eagle project volunteers who make keeping track of all these nests possible.”
The Division of Fish and Wildlife’s Endangered and Nongame Species Program (ENSP) bald eagle recovery efforts, implemented in the early 1980’s, have resulted in a steady recovery of New Jersey’s bald eagle population. ENSP biologists, Conserve Wildlife Foundation of New Jersey staff, and volunteer observers continue to locate and monitor bald eagle nests and territories each year to analyze the state of the population. The state’s eagle population would not be thriving without the efforts of the dedicated eagle volunteers who observe nests, report sightings, and help protect critical habitat.
The statewide population increased to 161 territorial pairs in 2015, up from 156 last year.
Thirteen new eagle pairs were found this season, nine in the south, two in central and two in northern New Jersey.
One hundred-fifty pairs were known active (meaning they laid eggs), up from 146 last year.
One hundred twenty-two nests (81%) were known to be successful in producing 199 young, for a productivity rate of 1.33 young per known-outcome active nest, which is above the required range of 0.9-1.1 young per nest for population maintenance.
One chick, orphaned from a Maryland nest, was fostered into a Cumberland County nest and fledged, bringing the total fledged to 200.
Twenty-eight (19%) nests failed to fledge young.
The Delaware Bay region remained the state’s eagle stronghold, with 40% of all nests located in Cumberland and Salem counties.
Freshwater mussels are distant relatives of marine mussels with a life cycle which includes a larval stage where they hitch a ride on fish as a parasite. There are a dozen species native to New Jersey and some species are known to live for over 100 years. This is an often overlooked group of species which deserves greater attention since many species are imperiled and because they are indicator species of water quality.
Conserve Wildlife Foundation of New Jersey (CWF) has partnered with the NJ Endangered and Nongame Species Program to create and release our latest Story Map, “Freshwater Mussels of New Jersey.”
This Story Map is a web-based field guide to New Jersey’s freshwater mussel species. The field guide explores the diversity of this group of species, how to identify them, their life history, threats and conservation measures, as well as providing range maps for each species. This is the only freshwater mussel field guide specific to the state of New Jersey and developed by state biologists.
Photos and interactive range maps are available for all 12 of New Jersey’s native species as well as several non-native species found within the state. Several short videos are also included which demonstrate different methods of surveying for freshwater mussels.
Funding for the creation of this Story Map was provided in part through a New Jersey Division of Fish & Wildlife grant.
Conserve Wildlife Foundation of New Jersey releases 2015 report

Conserve Wildlife Foundation today released the 2015 Piping Plover Breeding Report, highlighting the number of nesting pairs, pair productivity, and coast-wide distribution for this endangered shorebird, from data collected by New Jersey Division of Fish and Wildlife (NJDFW) biologists, CWF biologists, and other partners.
“The rebound in New Jersey’s piping plover breeding population and a second consecutive year of robust chick productivity was a much needed outcome,” said Conserve Wildlife Foundation Beach Nesting Bird Project Manager Todd Pover. “We need to continue our intensive management for a number of years to sustain any recovery, but we were very pleased to have finally broken the recent cycle of low nesting success and the record low number of nesting pairs in 2014.”
The piping plover – a small sand-colored shorebird that nests in New Jersey as part of its Atlantic Coast range from North Carolina up to Eastern Canada – face a number of threats, including intensive human recreational activity on beaches where they nest, high density of predators, and a shortage of highly suitable habitat due to development and extreme habitat alteration.
Federally listed as a threatened species in 1986, piping plovers have since recovered in some areas of the breeding range. Yet piping plovers continue to struggle in New Jersey, where they are listed by the state as endangered.
“As a species dependent on natural beach habitat, piping plovers face a particularly daunting challenge along New Jersey’s heavily developed and dynamic coast,” said Conserve Wildlife Foundation Executive Director David Wheeler. “Our dedicated scientists, partners, and volunteers are working tirelessly to ensure piping plovers remain a beloved and healthy presence along the Jersey Shore and beyond.”
CWF, in close coordination with NJDFW’s Endangered and Nongame Species Program, oversees piping plover conservation throughout New Jersey. Staff and volunteers help erect fence and signage to protect nesting sites, monitor breeding pairs frequently throughout the entire nesting season from March to August, and work with public and municipalities to educate them on ways to minimize impacts. Although conservation efforts on the breeding ground remain the primary focus, in recent years, CWF has also begun to work with partners all along the flyway, in particular on the winter grounds in the Bahamas, to better protect the at-risk species during its entire life-cycle.
2015 Report Highlights:
The population of breeding piping plovers increased 17% to 108 pairs in 2015, as compared to 2014. Despite the increase, the population still remains below the long-term average (118 pairs) since federal listing in 1986 and well below the peak.
The statewide fledgling rate, which includes data collected by partners at 19 active nesting sites throughout the state, was 1.29 fledglings per pair, down slightly from 2014 (1.36 fledglings/pair), but still one of the highest statewide levels since federal listing. Furthermore, both years were above the 1.25 fledgling rate believed necessary to maintain the range-wide Atlantic Coast population of piping plovers.
Statewide pair-nest success, the percentage of pairs that successfully hatch at least one nest, was high at 79%, well above the average since federal listing. Although population and productivity are ultimately the most important measures of recovery success, hatch success is an important metric to demonstrate the effectiveness of on-the-ground management.
Northern Monmouth County, as a region, continued to account for the largest percentage of pairs in the state (55 pairs or 51%), with Gateway National Recreation Area – Sandy Hook Unit accounting for most of those pairs.
The region comprised of North Brigantine Natural Area and the Holgate and Little Beach Units of the Edwin B. Forsythe National Wildlife Refuge accounted for the other significant concentration of breeding pairs in the state (43 pairs or 40% of the statewide total).
Holgate had the largest jump in abundance for any individual site, doubling its breeding pairs to 24 in 2015 (up from 12 in 2014). This increase was the result of highly suitable overwash habitat created at the site by Hurricane Sandy and the high breeding success that helped spur.
Cape May County, the southernmost region of the state, consisting of Ocean City to Cape May Point, continued its long-term downward trend, accounting for just 8 pairs in 2015, compared to 11 pairs in 2014 and 43 pairs in 2004 at its peak.

From left to right: Dr. Erica Miller, Edith Wallace, Linda Tesauro, Kathy Clark, Amy S. Greene, the Honorable Christine Todd Whitman, Pat Hamilton, MacKenzie Hall, Tanya Oznowich, and Diane Nickerson.
Our Tenth Annual Women & Wildlife Awards, held at Duke Farms, recognized three women – MacKenzie Hall, Pat Hamilton, and Tanya Oznowich – for their leadership in protecting wildlife in New Jersey. The Honorable Christine Todd Whitman served as the keynote speaker.
The Women & Wildlife Awards celebrated Conserve Wildlife Foundation’s past decade of honoring women for their success in protecting, managing, restoring, and raising awareness for the Garden State’s endangered and imperiled wildlife species.
“The inspiring leadership of MacKenzie Hall, Pat Hamilton, and Tanya Oznowich not only benefits New Jersey’s wildlife and the countless people who care strongly for our outdoors – it provides successful role models for the next generation of girls in scientific fields that have for too long held a glass ceiling for young women,” said CWF Executive Director David Wheeler. “Their unparalleled dedication and hard work – like that of the Women & Wildlife honorees over the past decade – has helped make New Jersey a national leader in wildlife conservation.”
The three honorees were recognized individually with awards in Inspiration, Leadership, and Education:
MacKenzie Hall, a powerful force behind the conservation of wildlife in New Jersey, who began working as a wildlife biologist for Conserve Wildlife Foundation in 2004 before joining the Endangered and Nongame Species Program in 2014, is the recipient of the Women & Wildlife Inspiration Award. She has been involved in a number of projects spanning bat colonies, migrating amphibians, and grassland birds.
In her work to implement conservation programs such as the Natural Resources Conservation Service’s Wildlife Habitat Incentive Program, Ms. Hall’s keen understanding of the process and positive attitude turned many farmers and landowners into dedicated environmental stewards. What may be most remarkable about Ms. Hall is her ability to motivate the public and inspire non-scientists of all ages to become passionate conservationists.
Women & Wildlife Leadership Award Winner Pat Hamilton has worked for the New Jersey Division of Fish and Wildlife Bureau of Freshwater Fisheries since 1980. She is considered to be the champion for Eastern brook trout, the state’s only native salmonid, and a species once extirpated from over 50% of its historical habitat due to human impacts.
Ms. Hamilton is one of three fisheries biologists in New Jersey endeavoring to strengthen the state regulations to further conserve native brook trout streams. Thanks to her efforts, more than 200 northern New Jersey streams have been designated as Trout Production Streams, which afford the streams higher levels of state protection.
The recipient of the Women & Wildlife Education Award is Tanya Oznowich, Environmental Education Supervisor of the New Jersey Department of Environmental Protection, who has championed environmental education for over three decades.
Schools across New Jersey are incorporating environmental education into their curriculum, a new movement inspired by a growing awareness of environmental issues and our shared role in understanding and resolving them. To a large degree, this growing prominence is thanks to Tanya Oznowich. She has been engaging the public in natural resources since 1979. Since beginning her tenure with the NJDEP in 1988, she has dedicated herself to integrating environmental science into New Jersey’s classrooms, from kindergarten to college.
The Tenth Annual Women & Wildlife Awards, held on Wednesday, October 28 at Duke Farms in Hillsborough, New Jersey, included a presentation of the awards to the recipients, hors d’oeuvres, cash bar and a silent auction.
We gratefully thank our generous Eagle Sponsors who made the Women & Wildlife Awards possible: PSEG, Atlantic City Electric, Janice King and Bill Masonheimer, and Eric Sambol.

Wildlife Biologist Celebrated for Inspiring Non-Scientists of All Ages to Become Passionate Conservationists
by Lindsay McNamara, Communications Manager
MacKenzie Hall, 2015 Women & Wildlife Inspiration Award Winner
A powerful force behind the conservation of wildlife in New Jersey, MacKenzie Hall began working as a wildlife biologist for Conserve Wildlife Foundation in 2004 and was been involved with projects spanning bat colonies, migrating amphibians, and grassland birds. What is most remarkable about Ms. Hall, however, is her ability to motivate the public to participate in these projects, inspiring non-scientists of all ages to become passionate conservationists.
Ms. Hall has supported and participated in bat research projects throughout the state. She took part in colony monitoring, mist-netting, and banding, working through many nights in order to benefit these enormously important species. In 2012, she launched a “Bats in Buildings” program offering New Jersey homeowners bat-friendly “eviction” resources, as well as free bat houses for displaced colonies.
In addition to her involvement in bat conservation, Ms. Hall is a passionate advocate for New Jersey’s amphibians and reptiles. She worked to address amphibian mortality on state roads, teaming up with working groups to help species of frogs and salamanders safely cross roads during their spring breeding season. She successfully coordinated amphibian surveys throughout the state, a task requiring road closures, the cooperation of multiple municipalities, the recruitment and training of volunteers, and the willingness to work outdoors overnight on cold, rainy nights!
We asked MacKenzie a few questions about what working in wildlife conservation means to her:
What motivates you to get out of bed each morning and go to work?
So much to do! Somehow the day always ends with more on the to-do list than it started with. Working statewide means a lot of ground to cover, a lot of emails to answer, and a lot of people to convince that the bats in their eaves aren’t looking to murder their family. Every day is a different adventure, even if I never leave my desk. Days that I actually get to spend up-close with animals or see our work making a difference – like finding kestrel eggs in a nest box we put up for them, or cupping a beautiful salamander in my hands and moving her to the safe side of the road – those are the little moments of glory that make it all feel so simple. It’s also really great to work with people who look at the world the same way I do, and who I can keep learning from.
What do you find most challenging about your profession?
Same answer as the last one, I think. This is work that’s never done. We rarely get to clap our hands together and say, “Ok, that species is saved, who’s next?” Most of our successes take years and years, a lot of educating others, a lot of help from others, and endurance.
Name one thing you can’t live without.
Sunshine…summertime. These crisp October days feel clean and refreshing, but I don’t want to close the windows and put a coat on! I want to bask in the sun like a turtle. I want sand that’s almost too hot to stand on. I want to run around in a tank top and pick berries and stay out in the balmy night in flip-flops, with frogs screaming from the trees.
What interests you the most about New Jersey’s wildlife?
Most of them live at or near some interface with the human world, because so much of New Jersey is covered in our footprints. We’ve got falcons on skyscrapers and shorebirds raising their chicks between houses and beach umbrellas. And yah, colonies of bats living up in the eaves. There’s a sense of sharing, because we’re all trying to make the most of our little spaces. We have so many chances to connect and commune with wildlife on common ground, if we just pay attention and learn to share nice.
Name one piece of advice you would give to someone who wants to change the world.
Figure out what you want the change to look like, and start with you. Be a positive example for the people who are close to you, and they’ll help you pass it forward. Don’t get too frustrated by the ones who don’t.
Please join us on Wednesday, October 28, 2015, from 6:00 – 9:00 p.m. at Duke Farms in Hillsborough, New Jersey to honor the contributions that MacKenzie Hall, Tanya Oznowich, and Pat Hamilton have made to wildlife in New Jersey.
This year’s very special event will feature keynote speaker Governor Christine Todd Whitman. The event will also celebrate CWF’s past decade of honoring women for their success in protecting, managing, restoring, and raising awareness for the Garden State’s endangered and threatened wildlife species.
On Saturday the 23rd, I received a call from Eagle Project volunteers Donna and Heiki Poolake. One of the nests that they monitor in Natural Lands Trust’s Glades Wildlife Refuge in Cumberland County had partially fallen and Heiki found all three chicks on the ground, thankfully alive. ENSP Principal Biologist Kathy Clark met them out at the nest site and determined that all three looked uninjured but were weak from lack of food and water. The two smallest were especially docile so the decision was made to take them to Tri-State Bird Rescue & Research in Delaware for a check up and to get needed fluids and food. The largest and strongest bird was given water and fish, and set on a leaning tree (off the ground) in the hope that it would hop up on branches where the adults, still watching from above, would continue to feed it.
The next day we pulled together a crew to install a nest platform for the remaining eaglet. We carried the pre-built nest platform (designed for ospreys) into the marsh, installed it and built a nest of branches and grass, and added perches to make it more roomy for an eagle. We found the eaglet back on the ground, sitting on the remains of the fallen nest. We caught the bird again, banded and took measurements that confirmed this was a female about 9 weeks of age. She gladly ate pieces of fish offered to her as well as some more water. We placed her up in her new “nest,” along with several fish, and she looked quite happy to be off the ground and back up in a nest.

In the meantime, the two eaglets at Tri-State were deemed healthy and ready to return to their parents. The challenge was how to return these two without disturbing their sibling now living in a nest platform built for smaller ospreys. The solution: a second nest platform. This second one was improved by CWF’s Ben Wurst by enlarging the size and adding branches as railings for perching. For a second time, a work crew assembled to use the early morning tide, and we boated the new platform out to within 200 yards of the first. The platform went up, a stick-and-grass nest quickly built, and the eaglets were brought out.
The eaglets, a 9 week old male and a 7.5 week old female, were kept covered until they got settled. When the chicks were uncovered, one of the adults started calling and flew in and perched on a snag within viewing distance. We quickly left and monitored them from a distance. One adult was perched near the platform with one eaglet, and before we left had flown in and perched near the new platform. Kathy went out the next day and reported that all three chicks were fine and using the perches and branches.

We’d like to thank the following people for their help: Dr. Erica Miller (NJDFW); Todd Vasquez (NJDFW Law Enforcement); Eagle Project volunteers Donna & Heiki Poolake and Matt Tribulski; Steve Eisenhauer (Natural Lands Trust) and local landowners, the Watermans.
