This year, we celebrate fifty years of one of the most critical conservation laws in the United States. On December 28th, 1973 the Endangered Species Act (ESA) was passed by Congress. The ESA has prevented 99% of all fish, wildlife, and plants under its protection from going extinct – an incredible feat. Scientists estimate more than 200 at risk species would have gone extinct if not for the development of the ESA. The ESA provides a legal framework to conserve and protect listed species and has safeguarded the biodiversity across the nation, supported the recovery of imperiled species, and conserved the critical habitats they depend on.
Piping plovers are just one at-risk species listed under the ESA.
Currently there are over 1,600 endangered and threatened species listed under the ESA in the United States. Once a species is listed, a full range of protections available under the ESA goes into effect, including prohibitions on killing, harming, or otherwise “taking” a species.

The ESA is fundamental to our work at Conserve Wildlife Foundation of New Jersey and has allowed us to be better ambassadors for New Jersey’s threatened and endangered wildlife.
Shortly after the USFWS announced that the Northern long-eared bat was being proposed for uplisting to an endangered species, another announcement regarding the tricolored bat was released.

In mid-September, the tricolored bat (Perimyotis subflavus) was proposed to be listed as endangered under the Endangered Species Act (ESA). Based on a thorough review of the species’ status, the Service found that the tricolored bat has declined dramatically across its range. Just as white-nose syndrome has been the cause of population decline for the northern long-eared bat, the tricolored bat has been similarly impacted. An estimated decline of more than 90 percent was found in affected tricolored bat colonies and white-nose syndrome is currently present across 59 percent of the species’ range.
WORLD IS EXPERIENCING A DECLINE IN POLLINATORS, NEW JERSEY IS NO EXCEPTION
By Kendall Miller
New Jersey is not exempt from the worldwide decline in pollinators. We face the challenge of protecting wildlife in a highly modified and populated landscape. But the fight is not without hope.
A milestone has been reached for wildlife conservation in Hawaii – and is a win for the world of conservation as a whole. This month, seven species of bees indigenous to the Hawaiian archipelago were added to the endangered species list and brought under federal protection. These are the first species of bees to be listed in the country.

In early June, CWF, in partnership with NJ Division of Fish and Wildlife, began the second year of the Northern long-eared bat mist netting and radio telemetry study. The team will be focusing efforts in Southern and Coastal New Jersey this year. The goal of the mist netting and radio telemetry project to learn more about the summer distribution and habitat selection of the federally listed Northern long-eared bat; an important project that can shed light on a species we know all too little about.
To date, the team has completed its second week of mist netting. So far, our team has caught 6 eastern red bats, 3 big brown bats and accidentally caught 2 flying squirrels in two different sites in southern New Jersey. Though a myotis bat has not been caught yet, the team did get acoustic detection of a tricolored bat (Perimyotis subflavus) foraging near the net site in Colliers Mills Wildlife Management Area in Jackson, New Jersey!

An Update on CWF’s Northern long-eared Bat Statewide Mist Netting Surveys
by Stephanie Feigin, Wildlife Ecologist

White-nose Syndrome (WNS), a fungal disease, has devastated bat populations across the country. Over six million bats have been killed by the disease, which has spread to over 25 states and five Canadian provinces. The Northern long-eared bat is one of the species most affected by WNS, suffering from an overwhelming 99% reduction in numbers in WNS-affected areas.

This summer, CWF Wildlife Ecologist Stephanie Feigin teamed up with NJDEP Division of Fish and Wildlife and Rutgers University to conduct a statewide mist netting and radio telemetry project to learn more about the summer distribution and habitat selection of Northern long-eared bats; an important project that can shed light on a species we know all too little about.
Mist-netting surveys began the week of June 1 and continued through the beginning of August. Survey sites included five state parks and Wildlife Management Areas across the state:
Sparta Mountain Wildlife Management Area
Rockaway River Wildlife Management Area
Washington Crossing State Park/Alexauken Creek Wildlife Management Area
Brendan Byrne State Forest
Wharton State Forest
The team, directed by Feigin, conducted a total of 19 netting nights and 10 tracking days, leading to a total of 63 bats caught, four of which were Northern long-eared bats. All four of the Northern long-eared bats received radio transmitters and were tracked everyday until the transmitter fell off.

After a long night of netting (5pm-2am) the team would set out the next day to track the bat caught the night before. This, however, was not an easy task. The maximum distance the antenna can receive a signal from the transmitter is ¾ of a mile (in perfect conditions). Though tough, the team was able to track the bats to five different roost sites including under the cedar siding of two homes, a narrow four foot stump, a large standing dead pitch pine, and another pitch pine in a recently burned forested area.
The mist netting and tracking study allowed us to collect important data on Northern long-eared bat populations throughout New Jersey. The data collected on habitat requirements and roost locations will help guide our conservation decisions. Ultimately, the study will allow us to better protect the remaining population of Northern-long eared bats in the Garden State.

This work was made possible with the support from the Franklin Parker Conservation Grants, EarthColor, and the Conserve Wildlife Matching Grant Program. Thank you to our supporters!
Remember back in late November when we wrote a blogencouraging our supporters to help the Northern Long-Eared Bat become listed as an Endangered Species? Thanks to those of you who submitted comments to the U.S. Fish and Wildlife Service, it was announced today that the Northern Long-Eared Bat will be listed as threatened and protected under the Endangered Species Act.
The U.S. Fish and Wildlife Service has cited declines caused by White-Nose Syndrome as well as continued spread of the disease, as the primary threat to the species. Under the protections of the Endangered Species Act, the Northern Long-Eared Bat now has increased priority for funds, grants, and recovery opportunities.
Also announced today, the U.S. Fish and Wildlife Service issued an interim 4(d) rule that will provide maximum protection to the Northern Long-Eared Bat in areas where their populations have drastically declined due to White-Nose Syndrome, but will limit regulatory burden on the public in parts of the country where the bat species is not affected by the disease and the populations are stable. The U.S. Fish and Wildlife Service invites the public to comment on this interim rule until July 1, 2015.
How Can You Help Protect Northern Long-Eared Bats?
Do Not Disturb Hibernating Bats
Leave Dead and Dying Trees Standing: Where possible and not a safety hazard, leave dead or dying trees on your property. Northern long-eared bats and many other animals use these trees.
Install a Bat Box: Dead and dying trees are usually not left standing, so trees suitable for roosting may be in short supply and bat boxes can provide additional roost sites.

As the summer leaves turn brown and children head back to school, flutters of black and orange wings flitter through the skies over the beaches in Cape May. As part of its yearly migration from Canada to Mexico, the monarch butterfly passes through New Jersey in search of a warmer climate for the blistery cold winter months. Multiple generations make the trek, leaving in the fall and returning in late spring.
During the summer months, the monarch can be found throughout the United States where milkweed, the species’ host plant, is plentiful. Milkweed provides nutrients to hungry caterpillars as well as space for mature females to lay their eggs. Although an adult monarch may lay up to 500 eggs in its lifetime, it has now been discovered fewer and fewer butterflies make the migration each year.
Losses of habitat and milkweed plants, the insect’s sole food source, are having tremendously devastating effects. According to a petitionfrom butterfly advocates, the North American population has declined by more than 90 percent based on comparisons of the most recent population size estimates to the 20-year average. Numbers of monarch butterflies east of the Rockies dropped to the lowest record ever, signifying a decline of more than 90% since 1995. Monarch numbers west of the Rockies showed a similar decline of more than 50% since 1997. These figures suggest a significant predicament as the North American population represents the vast majority of all monarchs in the world. Without it, the entire species is vulnerable to extinction.
On December 29th, 2014, the U.S. Fish and Wildlife Service announced it would be conducting a status review of the monarch butterfly under the Endangered Species Act (ESA). The Service has reason to believe a listing may be necessary due to considerable evidence from a petition submitted by the Center for Biological Diversity, the Center for Food Safety, the Xerces Society for Invertebrate Conservation and Dr. Lincoln Brower. The petitionstated that habitat destruction and loss of milkweed due to pesticide use are two of the most contributing factors to the declining monarch population. Other factors include disease and predation, overutilization for commercial purposes, and lack of existing conservation procedures.
To begin the status review, the Service is requesting scientific and commercial data and other information through a 60-day public information period. The Service is specifically seeking information regarding the following:
Subspecies’ biology, range and population trends, habitat requirements, genetics and taxonomy
Historical and current range, including distribution patterns
Historical and current population levels and current and projected trends;
Life history or behavior of the monarch butterfly that has not yet been documented
Thermo-tolerance range and microclimate requirements of the monarch butterfly
Past and ongoing conservation measures for the subspecies, its habitat or both
Factors that are the basis for making a listing determination under section 4(a) of the ESA
Starting on December 31, information can be submitted via www.regulations.gov by entering docket number FWS-R3-ES-2014-0056 in the search box and clicking on “Comment Now!” The information collection period will be open until March 2, 2015.
Until a decision has been made, take a moment to appreciate the beauty that is the monarch butterfly. Consider planting a few milkweed plants in your garden or speaking out against the overuse of pesticides. As much as the monarch butterfly’s migration is a group effort, the conservation of these beautiful creatures is even more so.

“Moonbird is the most famous, charismatic member of a group of mid-sized shorebirds called Rufa red knots, whose numbers have plummeted so dramatically in the past several decades that they just became the first bird ever listed under the Endangered Species Act with climate change cited as a “primary threat.”
Rufa red knots are among the avian world’s most extreme long range flyers (especially in light of their relatively small size). They travel vast distances — some flying over 18,000 miles — in the course of an annual migration that begins in Tierra del Fuego, Argentina, and extends all the way up to the Canadian Arctic (and back again).
Which brings us to Moonbird’s distinction: Because he is so old — he is at least 21 — he is believed to have flown as many as 400,000 miles in his lifetime. The distance to the moon varies, depending on where it is in its orbit, but the average distance is about 237,000 miles. Thus, Moonbird has not only flown the distance it takes to reach the moon — he has also covered the bulk of the return voyage.
Assuming that Moonbird is still living — the last sighting was in May — there are reasons to wonder whether there will ever be another bird that is his equal. Why? Simply put, his subspecies has been devastated, and climate change will only make matters worse — making extreme survival of the sort that Moonbird has achieved that much more difficult.”
Washington Post Science and Environment Reporter Chris Mooney explores Moonbird’s journey, threats to the species, and the recent Endangered Species Act listing of the Rufa Red Knot:
Wildlife conservation organizations leading the efforts to restore New Jersey’s Delaware Bay beaches for at-risk shorebirds today applauded the U.S. Fish and Wildlife Service decision to designate the Red Knot, a migratory shorebird, as “threatened” under the Endangered Species Act. A “threatened” designation means a species is at risk of becoming endangered throughout all or a significant portion of its range.
“This federal designation will make a big difference in strengthening the protections of this incredible shorebird,” said David Wheeler, Executive Director for Conserve Wildlife Foundation of New Jersey.
“Here in New Jersey, we are restoring the vital beach habitat that had been decimated by Hurricane Sandy, and this designation ensures the safeguards we are providing can be complemented along the East Coast,” Wheeler added.
Since the 1980’s, the Knot’s population has fallen by about 75 percent in some key areas. Wildlife biologists believe the major threat to the Red Knot is the dramatic decline of horseshoe crab eggs, an essential food source at the most critical stop over during their 8,000 mile trip from southern wintering grounds to Arctic breeding territory. High-energy horseshoe crab eggs provide nourishment for Red Knots to refuel and continue their journey.
“This is an important and needed step in the conservation and recovery of the Red Knot. It is an essential step in preventing the extinction of this amazing long distance traveler,” stated Tim Dillingham, Executive Director forAmerican Littoral Society.
The largest concentration of Red Knots is found in May in the Delaware Bayshore of New Jersey and Delaware, where the shorebirds stop to gorge themselves on the eggs of spawning horseshoe crabs. In just a few days, the birds nearly double their weight to prepare for the final leg of their long journey.
“The major decline of horseshoe crabs in Delaware Bay is one of the largest threats to the survival of the shorebird,” explained Dr. Larry Niles, a biologist who leads the beach restoration efforts for Conserve Wildlife Foundation of New Jersey and American Littoral Society, and has studied Red Knots for three decades. “Agency groups have been working hard for the last two years, and will continue for the next two years going forward to rebuild the habitat damaged by Hurricane Sandy that the horseshoe crabs rely on. This work is integral to the recovery of the Red Knot and the shorebird’s best hope for survival.”
In the wake of Hurricane Sandy, American Littoral Society and Conserve Wildlife Foundation of New Jersey worked with the U.S. Fish and Wildlife Service, the New Jersey Division of Fish and Wildlife and the New Jersey Recovery Fund to remove 8,000 tons of debris and added 45,000 tons of sand to the beaches just before the annual spring arrival of the Red Knot in 2013.
The U.S. Fish and Wildlife Service has reopened the public comment period on a proposal to list the northern long-eared bat as endangered under the Endangered Species Act (ESA). Comments will be accepted through Thursday, December 18, 2014.
The public is invited to submit comments one of two ways:
(2) By hard copy: Submit by U.S. mail or hand-delivery to: Public Comments Processing, Attn: FWS–R5–ES–2011–0024; Division of Policy and Directives Management; U.S. Fish and Wildlife Service, MS: BPHC; 5275 Leesburg Pike, Falls Church, VA 22041-3803.
The Northern Long Eared Bat, like many other bat species in the United States, is in danger of extinction due to White-Nose Syndrome, impacts to hibernacula, summer habitat loss and wind farm operation. Listing a species as endangered, under the protections of the Act, increases the priority of the species for funds, grants, and recovery opportunities.
