Our story map The Return of Bald Eagles in New Jersey has been updated based on the 2015 Bald Eagle Project Report. The story map shows the locations of every eagle nest known to be active (meaning they laid eggs) in New Jersey since 1985 — the year when there was only a single nest in the entire state. The map presents an animated depiction of where eagles have nested each year, so you can track the bald eagle’s triumphant return to the Garden State! Viewing the animation shows you how eagle nests spread from a single point in Cumberland County across all of New Jersey through the years.
The story mapalso highlights a number of Feature Nests which include more detailed information about the projects underway at specific nests, such as the Duke Farm nest which has been featured on our EagleCam since 2008.
The number of nesting pairs of bald eagles has steadily increased each year. This trend continued in 2015 with a record 150 active pairs, which was a slight increase over 146 such pairs recorded in 2014. In 2015, there were 122 nests that successfully fledged at least one young compared to 115 successful nests in 2014 and the 199 total young fledged in 2015 was only slightly less than the record 201 young fledged in 2014.
In New Jersey and throughout the world, almost every ecosystem is under some degree of disturbance caused by human impact. In particular, urbanization and deforestation often have negative consequences on ecosystems because they typically lead to overall habitat loss. A reduction in available habitat creates habitat fragmentation, where an ecosystem becomes segmented and broken apart. Habitat fragmentation can have multiple negative effects on wildlife, including dispersal, genetic isolation, and community structure impacts. Here in New Jersey, wildlife species are up against steady urbanization and a dense network of roads compromising the connectivity of habitat and wildlife populations. Today, the state of New Jersey remains the most densely populated state in the country occupying about 39,000 miles of public roads.
Connectivity is vital for wildlife. Different color habitat patches represent different resources essential for survival. Lines represent possible corridors connecting patches.
In order to maintain diversity and sustain healthy wildlife populations, we must connect various fragmented habitats and wildlife communities. Animals need to be able to move through the landscape to find food, shelter, mates, and other resources. Without that ability to move, healthy populations cannot persist over the long term. In order to curb the effects of roads and habitat fragmentation, wildlife road crossing structures can be installed to reduce wildlife road mortality. In addition, wildlife habitat corridors can be prioritized for land management, restoration and acquisition.
What is New Jersey doing to create habitat connectivity for our state’s diverse wildlife?
Connecting Habitat Across New Jersey(CHANJ) was formed in 2012 by the Division of Fish and Wildlife, with the vision of making our landscape and roadways more permeable to wildlife movement. CHANJ represents a blueprint for strategic habitat conservation that will identify key areas and the actions needed for preserving and restoring habitat connectivity for terrestrial wildlife in New Jersey. CHANJ has the potential to increase the sustainability of New Jersey’s terrestrial wildlife populations and de-list endangered species. Connecting populations of wildlife will improve gene flow and allow wildlife to move freely throughout the landscape.
How can you help?
Be mindful of wildlife while driving: Peak wildlife crossing season occurs in the spring and summer as wildlife travel to find food and mates. If wildlife such as amphibians and turtles are on the road, safely pull over and carry them to the shoulder in their direction of travel. Always be mindful of safety and do not attempt to handle any wildlife if you are not comfortable.
On our Expedition to Study Shorebirds along the Northern Coast of Brazil
By: Dr. Larry Niles, LJ Niles Associates LLC
Ana Paula with Red Knot
The largest mangrove forest in the world covers the Brazilian coastline at the equator near the mouth of the Amazon river. The forest extends out into the Atlantic in long peninsulas tipped by wind swept and mostly inaccessible beaches. The forest, beaches and their long intertidal mud and sandy low tide flats support the largest wintering population of shorebirds in the hemisphere, perhaps the world. The red knot, a listed species in both North and South America, also uses this remote tropical coast.
Boat Trip RouteCatamaran
With scientists from the U.S., Canada, England and Brazil, we will attempt a large scale mapping of this important habitat using state-of-the-art satellite mapping. We will do this from a 50-foot catamaran and two zodiacs hopping from one mangrove estuary to another and conducting bird surveys targeting key areas over a 150 mile-section of the coast. We will be the first to survey some areas. Our goal is to figure out the main threats to both bird and habitat.
To understand the importance of this area one has to think about it like a shorebird. Although born in the Arctic they actually spend only a few months there. They spend a few months moving from their nesting area to their wintering area. They spend the rest of their lives, the majority of their year in the wintering area. A threat to the wintering area would be grave.
Most of our survey zone is part of the Reentrancias Maranhenses, a protected area of the state of Maranhao, Brazil. Our catamaran captained by William Thomas will leave from a small town near the city of Sao Luis, Brazil. From there we will sail along the coastline moving in and out of the mangrove islands to survey shorebirds, habitat and marine invertebrates. We will “geo reference” all data, or take detailed coordinates so the data can be reproduced on satellite mapping.
Satellite Map
Satellite maps aren’t really maps as most people understand — pictures or drawings of a section of the earth — they are digital files of remotely sensed data, they are only wavelengths of light that must be interpreted to represent actual habitat. We will train the satellite data so that each habitat will be represented by a combination of spectral data — colors in sense.

Once completed, we can relate the habitat maps with information on birds, their prey and equally important, the threats to the birds and prey. For example, shrimp farming is growing in this area. Entrepreneurs are stripping the intertidal zone of mangrove forest, diking the area and then growing shrimp. Once the area accumulates too much waste and chemicals, they abandon the site and move on to damage another mangrove forest. We will determine which areas are of importance to the birds and potential targets for shrimp farmers. But there is more: oil spills, disturbance from tourists, water pollution are among many.
Over the next three weeks, we will be reporting on our work on this blog.
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.
New Video Showcases CWF’s Work to Protect the Garden State’s Wildlife

By: Kathleen Wadiak, Wildlife Conservation Intern
Conserve Wildlife Foundation’s 2015 Species on the Edge Art and Essay Contest gave fifth grade students from across the state the opportunity to research an endangered species and submit a drawing and essay written from the animal’s perspective. Meant to support awareness of endangered species in students, the Species on the Edge Art & Essay Contest encourages fifth graders to think like wildlife biologists as they gather research and learn about pressing environmental issues. The results of this contest are the subject of our newest story map!
This interactive map allows the user to click on icons to see participating schools, first and second winners from each county, and honorable mention entries. Scrolling through the text on the left side changes the content of the points on the map. A click on each map point brings up more information, like the number of classes from each school that submitted an entry. While scrolling through the list of winners, users can even click on the schools’ icons to bring up the students’ names, essays, and artwork.
The format of this story map is simple and easy to use, allowing for an interesting, interactive way to display the hard work of students across New Jersey.
Conserve Wildlife Foundation of New Jersey Releases a New Story Map: “Harbor Seals in New Jersey”
By: Michael Davenport, GIS Program Manager
Conserve Wildlife Foundation of New Jersey (CWF) has partnered with Jenkinson’s Aquarium of Point Pleasant Beach, New Jersey to create and release our latest Story Map, “Harbor Seals in New Jersey.”
Over the years, CWF staff have worked with a number of marine biologists in order to monitor seal populations in New Jersey and minimize disturbance or harm to them. Most recently, CWF held two workshops in 2014 to educate first responders on handling marine mammal (and sea turtle) strandings. We’re continuing our efforts at educating the public about these amazing animals with our “Harbor Seals in New Jersey” Story Map. A Story Map is a web-based interactive map embedded with multimedia content, such as text, photographs, and video.
The release of this Story Map coincides with the renovation of the seal exhibit at Jenkinson’s Aquarium. Jenkinson’s has been home for harbor seals since 1991, when their first seal (“Luseal”) moved in. She was soon joined by another seal, “Seaquin.”
This Story Map provides general information about harbor seals: where they live, how they live, and what dangers they face in the wild from both predators and humans. Luseal and Seaquin also have pages devoted to them, with photos and interesting facts about their lives and behaviors.
CWF Releases its First Annual Report Ever Using a Story Map Format: “2014 Annual Report“
By David Wheeler, Executive Director
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 2014 Annual Report in a unique format that utilizes one of those technologies – Story Maps. In the past year, we have explored the wonders of American oystercatchers with our first Story Map – and now the annual report allows all of our projects to be highlighted in this interactive format.

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 2014 – a great year for wildlife in the Garden State!
Data nerds rejoice! Today, Wednesday, November 19 is GIS Day. Geographic information systems (GIS) technology helps our wildlife biologists protect rare species throughout New Jersey. GIS technology is used to create our species range maps and other important tools that show where wildlife occur and what habitat they need to exist.
Conserve Wildlife Foundation is a key player in updating the NJ Endangered and Nongame Species Program’s (ENSP) database of rare wildlife species. The database called “Biotics” is a GIS and Oracle-based system developed by NatureServe, the leading source of information on the precise locations and conditions of rare and threatened species and ecological communities in the Western Hemisphere.
Although CWF and ENSP biologists submit a majority of the data on Biotics, we rely on the help of citizen scientists to fully understand the wildlife picture in New Jersey. Do you want to help biologists monitor certain areas of the state and locate the presence of species of concern? Visit our website to learn how you can get involved.
In addition to the Biotics database, GIS was used to create range maps for all 190 species featured on our online field guide! Check it out.
Have you seen our American Oystercatcher Story Map? GIS was used to create that tool as well! A Story Map is a web-based interactive GIS map embedded with all kinds of content, like text, photographs, and video.
CWF Celebrates World Shorebirds Day With Release of Our First Story Map: “American Oystercatchers Through the Seasons”
By Michael Davenport, GIS Program Manager
Conserve Wildlife Foundation (CWF), today released a new interactive “Wildlife Story Map” in support of this Saturday’s first annual World Shorebirds Day! The Story Map can be viewed here!
A Story Map is a web-based interactive GIS map embedded with multimedia content, such as text, photographs, and video. CWF, working with GIS software developer ESRI and with financial assistance provided by a grant from the New Jersey Division of Fish & Wildlife, plans to make this Story Map the first of many, helping engage the public about New Jersey’s rare wildlife in a dynamic and interactive way.
“American Oystercatchers Through the Seasons” tells the story about a species of migratory bird, the American Oystercatcher, which spends the summer breeding season along the New Jersey coast, but is present year-round along the southern New Jersey coast. Our state represents the northern limit of the species’ winter range. While some New Jersey birds migrate during the winter to Florida, those that breed in New England during the summer may end up spending their winter here in New Jersey.
This Story Map also provides stories about individual banded birds, which have been tracked on journeys between New Jersey and southern states such as Florida, as well as between New Jersey and more northern states, such as Massachusetts.
Make a donation today to support additional Story Maps!
How to Use the Story Map:
On the left side of the Story Map page are several “buttons” which will allow you to flip through the different seasons in an oystercatcher’s life: Breeding, Migration, and Wintering. Each page provides information and photos and a map specific to that portion of the bird’s life cycle. By clicking on an individual point within the map, a box containing more specific information, and a photo in some cases, will pop-up. The map also provides the ability to zoom-in and out in order to see areas of interest in more detail.
This Story Map is especially exciting since it helps celebrate the first annual World Shorebirds Day. This event seeks to “…raise global public awareness about the conservation of, and research about, shorebirds. About half of the world’s shorebird populations are in decline, and the rate of habitat loss is worse than ever before” (World Shorebirds Day 2014).
World Shorebirds Day hopes to accomplish the following:
To raise public awareness about the need to protect shorebirds and their habitats throughout their life cycles;
To raise public awareness about the need for ongoing shorebird research;
To connect people with shorebirds through important shorebird sites around the world;
To get shorebird enthusiasts to introduce shorebirds to more birdwatchers;
To raise awareness about the need for increased funding for shorebird research, monitoring and conservation.
CWF’s shorebird leadership ranges from the American Oystercatcher celebrated in this Story Map, to the beach nesting birds along the Atlantic Coast, to the red knots and ruddy turnstones along the Delaware Bay.
Your support can help CWF develop additional Story Maps on other rare wildlife. Support our work on Story Maps on the American Oystercatcher and other important shorebirds in honor of World Shorebirds Day by supporting research, education, and public awareness efforts carried out by CWF:
We hope that this will be the first of many Story Maps that CWF will use in order to communicate the many fascinating stories that New Jersey’s wildlife have to tell.
