Anyone already planning their fishing trip to their favorite stream this spring? Sunshine and cool refreshing streams will be here before you know it!

Streams and rivers are an essential part of our ecosystem, providing food, shelter and breeding grounds for hundreds of New Jersey native wildlife, as well as providing water for human use. These wildlife include, macro-invertebrates, reptiles, birds and fish such as the Eastern brook trout. The Eastern brook trout is valued for its beauty, sport-fish qualities and is an indicator of the health of our watershed. It is also the only native trout species in New Jersey, but is unfortunately threatened by urbanization and dense road networks which contribute to sedimentation, warmer waters and pollution.

This past year, CWF biologists along with our partner agency USDA’s Natural Resources Conservation Service (NRCS) have been working in conjunction with New Jersey Audubon Society to improve stream habitat throughout about 5,000 feet of the Musconetcong River. The Musconetcong River currently supports brown trout, and through restoration of the watershed it has the ability to support Eastern brook trout as well.

In order to restore the reach of the Musconetcong River, pool and riffle sequences were created and deep pools and point bars were established in the stream channel. These restoration techniques provide spawning habitat for trout, as well as benefit the organisms they depend on for food. Furthermore, the restoration of appropriate channel morphology helps to create a healthy riparian zone through the enhancement of flood plain connectivity.

CWF and USDA-NRCS continue to work with farmers and other landowners to plant stream-side shrubs and trees, fence livestock out of waterways, remove dams and use less pesticides in order to promote healthy watersheds. These practices will not only help prevent pollutants from reaching our waterways, but they will help maintain functioning ecosystems that will digest and filter pathogens and sediment. This collective effort by local land managers and landowners will enable us to protect human health, assure clean water and preserve our quality of life for generations to come.

Science in the Mangroves

Update from Brazil: “We are Going to Have to Science the ‘Heck’ Out of This”

by Dr. Larry Niles, LJ Niles Associates LLC

We came to Brazil to conduct a rigorous scientific study of the wintering population of shorebirds in a place where the land and sea act against any rigorous protocol. It would be easier to just go out and count birds and identify their habitats and prey, but our charge is more difficult.

The survey wraps around satellite imagery, strange unintelligible wavelength data coming from satellites hovering over the earth that can be transformed into brilliant and useful maps in the right hands. Those hands belong to Professor Rick Lathrop and his post doc Dan Merchant. Rick leads the Center for Remote Sensing at Rutgers and he and I have collaborated on projects ranging from municipal habitat conservation planning to Arctic red knot habitat mapping. He has created one of the most alarming maps that every person from New Jersey should know about.

nj_landchange450

The mapping of Reentrancias Maranhenses, an internationally recognized site of ecological importance is especially tricky. Our research platform is a 50-foot boat and we will be out of cell and internet contact for much of the time. Our method of collecting data for the mapping was devised by the whole team, but especially with the help Professor David Santos of the University of Maranhao, my colleague Dr. Joe Smith and Humphrey Sitters of the International Wader Study Group.

It focuses on collecting bird and habitat information using randomly selected survey points. In other words, we will try to pick places at random to survey so that when we combine them we will have a sample that represents the entire area, not just the places we surveyed. It’s like trying to figure how many different kinds of chocolates are in a valentine. If you take them all from one side then you might have sampled the chocolate covered cherry section leading to believe they are all one kind. But if you choose chocolates at random than you will find the box includes other kinds, caramel or fruit or nutty chocolates. This is making me hungry, but you get the point.

The area of our box we is very large, bigger than New Jersey, and it grows and shrinks every day with the tides. So, sampling is tricky business because a sample at low tide, when the tide is out exposing vast areas of intertidal mud and sand flat, is very different than when the tide is high. So we will be classifying habitat, or stratifying it, so we can focus on limited survey time to get the best sample.

Once collected we can start making maps. All data will be geo referenced – or located precisely with GPS units – so it can be accurately mapped. With this, we will train the satellite maps to outline the habitat best for shorebirds.

All this while exploring areas that have received little scientific scrutiny and under tropical conditions, almost daily rain, a persistent 20 mph wind and summer heat. Add parasites, mosquitoes and diseases like malaria and one can see this a rugged undertaking.

Our crew is up to it. Besides those mentioned above Mark Peck from Royal Ontario Museum, Danielle Paluto from the Brazilian CEMAVE (a counterpart to our USFWS), Steve Gates a veteran of expedition on other SA trips, shorebird expert Dr. Mandy Dey, Stephanie Feigin from Conserve Wildlife Foundation of New Jersey and the author round out a dream team of bird study in difficult places.

CWF Biologists Travel to Brazil to Study Red Knots

Posted on January 20, 2016 by CWF

On our Expedition to Study Shorebirds along the Northern Coast of Brazil

By: Dr. Larry Niles, LJ Niles Associates LLC

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.

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 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.

New Jersey’s Bald Eagle Population Continues to Soar

Posted on January 14, 2016 by CWF

Conserve Wildlife Foundation of New Jersey releases results of 2015 State Bald Eagle Report

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 EagleCam has 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.

Highlights of the 2015 New Jersey Bald Eagle Project Report are found below or view the complete report online.

2015 Report Highlights

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.

Walking the Land

Posted on January 8, 2016 by CWF

CWF Biologists’ Winter Field Work

by Kelly Triece, Private Lands Biologist

Even during these cold winter months Conserve Wildlife Foundation biologists are out in the field! The winter is often the best time of year to fully see the land and make accurate assessments on potential management. My role as a Private Lands Biologist along with our partner the U.S. Department of Agriculture, Natural Resources Conservation Service (USDA-NRCS), is to work with private landowners and help them manage their property for the benefit of wildlife and to conserve other natural resources.

Often times this means walking the property with landowners who are interested in enhancing or providing habitat for wildlife. On our walk, we look for invasive species, erosion concerns, existing hydrology, native vegetation and the potential to enhance the property for wildlife. We make recommendations on how to best manage the land for wildlife, but ultimately it is up to the owner.

Winter Field Work — Potential enhanced waterfowl and amphibian habitat.

This winter, I have met with several landowners whose goal is to provide waterfowl and amphibian habitat on their land. We have also visited forested lands to determine their suitability to create Golden-winged Warbler habitat, an endangered songbird.

Not every day is a close encounter with wildlife! But helping private landowners learn about sustainable land management and implement conservation goals on their property may help provide food, water and breeding grounds for many of New Jersey’s native wildlife species.

New Jersey Tiger Season

Posted on December 17, 2015 by larissasmith

Biologists and volunteers survey for New Jersey Eastern Tiger Salamanders

by Larissa Smith, biologist/volunteer manager

It’s the time of year when Conserve Wildlife Foundation biologists and volunteers along with Endangered and Nongame Species biologists start to survey for New Jersey’s “tigers,” and by tigers I don’t mean the big striped cats, we’re talking about the Eastern Tiger Salamanders. These large mole salamanders spend most of their life burrowed under the ground and in December begin to emerge to migrate to vernal pools and breed. Eastern Tiger Salamanders are endangered in New Jersey and only found in 15 pools in the most southern part of the state.

Last week dedicated volunteers Wayne Russell, John King and myself went out to check on a few known breeding pools. The water level in the ponds was lower than usual due to the lack of rain, but John found an adult male in one of the pools.

We were delighted to find a male in the pool so early in December. At another known breeding pool we found the partial remains of two Eastern Tiger Salamanders that had obviously been eaten by a predator. But the good news was that we also found two tiger salamander egg masses in the same pool.

Predation is just one of the challenges that these salamanders face. Tiger Salamanders themselves are targeted by collectors for the pet trade which is why their breeding locations are kept a secret. Their habitat is declining due to habitat loss and fragmentation, development, pollution, changes in hydrology, and climate change.

Providing Young Forest Habitat for the Golden-winged Warbler

Posted on December 11, 2015 by CWF

CWF and partners have created or restored over 225 acres of Golden-winged warbler habitat in New Jersey since 2012

by Kelly Triece, Private Lands Biologist

Take a look at this Golden-winged warbler — a Neotropical Migrant songbird that breeds in New Jersey. This songbird is a species of special conservation concern in the United States and endangered in New Jersey, experiencing population declines due to loss of young forest habitat.

Did you know? In the past 30 years, over 11,000 acres of upland shrub and emergent wetland habitat have been lost to succession in New Jersey. This habitat is important for Golden-winged warblers because it is their primary breeding habitat. Fortunately, their secondary habitat, upland forests, have remained stable in the state.

Therefore, it has been the goal of many wildlife management agencies to continue to create young forest habitat, while protecting upland forests as well.

Conserve Wildlife Foundation and our partners (Natural Resources Conservation Service, New Jersey Division of Fish and Wildlife and New Jersey Audubon Society), have worked with private landowners to create or restore over 225 acres of Golden-winged warbler habitat since 2012 in New Jersey.

Our managed forests have a statistically significant higher diversity of birds than unmanaged sites!

Young forest habitat, also known as scrub-shrub habitat, is new or regenerating forest that is less than 20 years old. Young forest habitat is important for many birds, especially the Golden-winged warbler. The open canopy of a young forest also helps provide food such as berries and insects to newly fledged birds, wild turkey, ruffed grouse, reptiles, black bears, bobcats, and butterflies.

The breeding range of the Golden-winged warbler extends along the Appalachians from the northern portion of Georgia in the south to Vermont in the north. The winter range for this species is southern Mexico and Central and South America.

Follow us in February 2016 when biologist Kelly Triece travels to Honduras to see the Golden-winged Warbler in its winter habitat!

Piping Plover Population Rebounds from Historic Low in New Jersey

Posted on November 19, 2015 by CWF

Conserve Wildlife Foundation of New Jersey releases 2015 report

by Todd Pover, Beach Nesting Bird Project Manager

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.

Osprey Pair Get A New Home

Posted on November 12, 2015 by larissasmith

Students install a new nesting platform for Avalon ospreys

by: Larissa Smith, Wildlife Biologist/Volunteer Manager

Volunteers and Students from Cape May County Technical School

One lucky pair of ospreys received a brand new nesting platform due to the effort of volunteers and students from the Cape May County Technical School! Dedicated osprey project volunteer Matt Tribulski reached out to CMC Tech Natural Science teacher Hanna Toft, regarding replacement of an aging platform in the Avalon back bay. Hanna is an osprey project volunteer and bander and incorporates the osprey project into her curriculum. The nest that was replaced was an old four poster that was unstable and not predator proof. The nest was located at the edge of the water causing the birds to get off the nest every time a boat or jet ski went by (which in the summer is quite frequently).

Hanna had a platform available that her students had built last year. We couldn’t have picked a better day for the install, the weather was gorgeous and warm for November. We met Hanna and eight of her students out on the water. The new platform was placed further back from the water and has a predator guard. The students removed the old platform, leaving some posts for the ospreys to perch.

We hope that the birds like their new home when they return in the spring.

Thank you to Matt, Hanna and her students for all of their help!
