Princeton Seventh-Graders Protect Bats through Hands-on Research Project

Students partner with nonprofit Conserve Wildlife Foundation to design better bat houses

By Stephanie Feigin

Although bats have a reputation of being dangerous and scary, these flying mammals are something to be coveted, and the students at Princeton Day School know why. Seventh grade students Albert Ming, Arjun Sen, Martin Sen, Dodge Martinson, Kai Shah, and Samuel Tang teamed up with Conserve Wildlife Foundation to design a better construction plan for bat houses. The students hope to promote better conditions for bats living in Central Jersey.

Bats are in the midst of tragic declines as a consequence of habitat loss and a devastating fungal disease known as White-nose Syndrome. CWF works to preserve bats, which basically provide a free pest removal service. A single bat can consume up to 3,000 mosquito-sized insects in one night! Their value to agriculture is estimated at $53 billion annually in the United States alone. Not to mention they provide mosquito and biting insect control, which are not only a nuisance but also have disease spreading potential.

Many bats in New Jersey have come to depend on manmade bat houses, structures specifically designed and placed for the needs of the bats, and the Princeton Day School students stepped up to help.

First, the students researched the best, most economical type of wood to use for construction. Next, they used an infrared thermometer to see how well heat is absorbed and retained by the different wood types after they were painted and stained using three different colors.

Keeping the inside of a bat house within the right temperature range is vital to the survival of bats, especially the vulnerable young pups. If a bat house becomes too hot (above 95 degrees) or too cold (below 65 degrees), the health of the bats is threatened. Bats move their pups from house to house in search of the right temperatures.

The students used the results of their temperature experiment and high and low temperature readings for Central Jersey over the past three years to design a plan for a bat condo unit that would satisfy bats temperature requirements during their entire six month roosting period.

The x – axis is the number of hours passed during the day and the y- axis represents degrees Fahrenheit.
This graph displays the research for the best type of wood (cedar, pine or plywood) to use for constructing bat houses, along with different kinds of paint (adobe, slate or russet) to determine which combination could retain the most heat for the bat colonies. Heat retention was measured over a long period of time while exposed to the sun.
The research revealed that the bat houses are most successful if they are painted or stained and weather resistant wood like cedar would last much longer than softer wood like pine or plywood. When cedar wood was used the temperature changed the most as the air temperature changed and the least when sunset came. When plywood was used the temperature changed the least as the air temperature changed and the most when sunset came. When pine wood was used the temperature changed moderately as the air temperature and moderately when sunset came.
The conclusion made was that there are differences among wood and paint combinations. Adobe paint on plywood has the smallest average temperature change even though the difference is not statistically significant and adobe paint on cedar had the smallest temperature change between 4 and 6 degrees. They chose adobe paint on cedar or plywood as they are also the most cost effective.

With the results of their research and experiments, the students made informed decisions to design the bat boxes. The final product was three bat houses built using plywood. They painted one of the houses in a black slate color to provide maximum heat during the colder months, and painted a second house in an adobe beige color to provide air conditioning during the hot summer months. Lastly, they chose a russet color to for the moderate months.

CWF Wildlife ecologist Stephanie Feign who worked with the students on the project was happy to see how passionate these kids were to learn and be hands-on. “Their passion and enthusiasm were inspiring. Projects like these not only benefit wildlife, but also benefit surrounding communities and provide experiential learning for students.”

New Jersey is home to nine different species of bats, two of which are listed as endangered or threatened. Six species that do not migrate south for the winter remain in New Jersey to hibernate in a cave or another safe place. When they awake from hibernation in April, the females search for roosting spots to bear and raise their young pups. With so few intact forests in New Jersey, bats are struggling to find places to safely roost.

That is why projects like this one with Princeton Day School are essential for preserving bats. Not only did the projects help bats, but it also helped the students by requiring them to use problem solving and critical thinking skills to protect a creature that they came to value. Wildlife, which kids become excited and passionate about, is a valuable educational tool.

The team is currently working with Princeton Day School facilities to erect the bat condo unit on campus. Hopefully, by next spring, the school will be home to many new, very comfortable bats.

New Jersey Gains Another Endangered Species: The Rusty Patched Bumble Bee

First bee in continental U.S. added to endangered list

By Kendall Miller

The rusty patched bumble bee has been locally extinct from the Garden State since the late 1900s. Once a common sight, the species has been eliminated from 87% of its entire range and has been seen only in isolated pockets of its once wide range.

But finally, the long awaited day has come – the rusty patched bumble bee has officially been added to the Endangered Species List.

The Rusty Patch Bumble Bee is found only in isolated pockets of its former range. Photo taken from Xerces Society.

The Xerces Society for Invertebrate Conservation first petitioned for the listing of the rusty patch in 2013. The decision to list was finally reached in September of this past year, and the Rule was officially published on January 11, 2017. The official Ruling brings the species under the protection of the Endangered Species Act, which will enable it to receive much needed federal protection.

Following the listing of seven yellow-faced bees found only in the isolated archipelago of Hawaii this September, the rusty patched is the first bee to join the ESL that is native to the continental U.S. It seems as if it has not been a good couple of months for bees, however this perception is far from the truth. Pollinators are on the decline across the globe as a result of pesticides, habitat loss and degradation, and the spread of pests and diseases. Listing pollinators for the first time means that their plight is recognized, and it empowers those who are working to protect these species from extinction.

Rare find, this is a species that has suffered drastic declines since the late 1990’s. Photo courtesy of Dan Mullen.

The multitude of ways that we rely on pollinators – for food, clothes, ecosystem functioning – means that their peril is our own. In New Jersey, the service provided by *wild pollinators is valued at $43 million; in the U.S. as a whole, it is $3 billion annually. Since the rusty patch (along with other species of bumble bees) is an excellent pollinator of New Jersey crops like blueberries, cranberries, and tomatoes, it is sorely missed from the Garden State.

This listing is another small step for the protection of native bees and pollinators everywhere.

Helping pollinators takes three steps:
1.  Plant flowering nectar sources spring through fall
2.  Provide safe nesting and overwintering habitat
3.  A pesticide free environment

 

*Wild pollinators are native bee species like the rusty patch bumble bee that have evolved with their native ecosystems. Honey bees that are commercially used for agriculture pollination services and honey production are not native to the United States.

In season for giving, donor helps wildlife supporters double their gifts

DONATIONS TO BENEFIT CWF WILDLIFE EDUCATION PROGRAMS

By Emily Hofmann

Newark 5th-graders enjoy a day at the beach exploring nature as part of CWF’s WILDCHILD Program for underserved youth.

Connecting kids with the natural world around them does wonders for their health and self-esteem, builds leadership skills, and often fosters a love of science at a very young age.

And nothing awakens that environmental awareness like wildlife!

Conserve Wildlife Foundation’s exciting hands-on programs – classroom presentations, field trips, live wildlife, and webcam lessons – teach children about the state’s rare wildlife and the need to protect it. And while some schools can cover the costs of these lessons, far too many can’t afford programs and field trips.

Through December 31, all donations to Conserve Wildlife Foundation to support our education and outreach to under-served schools will be generously matched by the Merrill G. & Emita E. Hastings Foundation. This will greatly strengthen CWF’s ability to provide equitable opportunities for children in at-risk areas to become environmental stewards.

Thanks to that generosity, a donation of $25 will be worth $50, and a donation of $100 will be worth $200.

Learning about the eagles, ospreys, bats, peregrine falcons, butterflies, and other animals that might share their neighborhood engages kids with their environment,” says Liz Silvernail, CWF Director of Development. “Our education helps open children’s eyes to the wonders of wildlife and nature, regardless of whether their school can pay for our programming.”

This holiday season, CWF encourages supporters to give the gift with an enduring legacy for the next generation of scientists!

First Bees Added to Endangered Species List.

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.

Autumn in New Jersey: Why Do Trees Shed Their Leaves?

By Kendall Miller

It’s that time of year again. The trees around us, in our yards, on our streets, and in our forests are shedding their leaves with each gentle breeze or strong gust of wind. A dazzling display of colors drew tourists to gaze at our Northeast forests. After the brief but beautiful show, the leaves drift to the ground to litter the forest floor.

autumn-3

Our red, white, and black oaks, red and sugar maples, american beech, hickory, and cherries and other deciduous trees that dominate New Jersey forests all drop their broad leaves on cue. The few evergreen firs, spruce, and pines that we have hold on to their needle-leaves and contribute to the little greenery we have in the landscape until the following spring.

Wendy Walsh, 2016 Leadership Award Winner

As a Senior Fish and Wildlife Biologist at the United States Fish and Wildlife Service, 2016 Women & Wildlife Leadership Award Winner  Wendy Walsh has proven herself invaluable in the endangered species field for her work with wildlife such as the piping plover, swamp pink, and seabeach amaranth. Her most notable work is with the red knot. Ms. Walsh took the species lead in the middle of the federal listing process. Her tireless efforts coordinating, analyzing and interpreting data, particularly detailing the effects of changing climate on these long-distance migrant shorebirds has made her work widely acclaimed as the final rule. From biology to policy, she has an uncanny ability to grasp important information and translate it for any species she finds herself working with. She has created partnerships with additional organizations to accelerate conservation efforts. In such collaborations, Ms. Walsh’s open-mindedness to others’ expertise makes for effective planning and implementation of the vision she has to one day recover all threatened and endangered species.

Join us to honor Wendy and the two other 2016 Women & Wildlife Award Winners on Wednesday, November 30th beginning at 6pm. Purchase events tickets and find more information.


CWF asked Wendy a few questions about what working in wildlife rehabilitation means to her:

 

What motivates you to get out of bed each morning and go to work?

“Engagement with the work. Of course there are those mundane tasks we all have, but in general I find my work highly engaging. Sometimes when I’m at home, I’ll think of some new resource or approach to a conservation problem I’ve been working on — then I can’t wait to bring that idea to the office and try to apply it. When it works, my job can also be very rewarding.”

 

What is your favorite thing about your job?

“I love that I’m constantly learning something new. Over the years, I’ve had the chance to learn about and observe so many species, and I’ve had the chance to really get to know a few in particular — piping plovers, seabeach amaranth, bog turtles, swamp pink, and red knots. And I’ve had the opportunity to work on such a wide range of issues — utility lines, transportation, mitigation, stormwater, beach nourishment, bird collision, volunteer programs, restoration, fishery management, listing, and most recently aquaculture. I’m very fortunate to have a job where there is always a new learning opportunity on the horizon.”

 

Do you have a New Jersey wildlife species that you like best? Why?

“From a non-scientific point of view, I love watching dragonflies and wading birds with my kids, and taking the family to count and tag horseshoe crabs. But professionally, I’m partial to the beach species I’ve worked on — piping plovers, red knots, seabeach amaranth. I enjoy the beach ecosystem, and I feel a responsibility to these beach-dependent species that face so many challenges along New Jersey’s human-dominated coast.”

 

What interests you the most about New Jersey’s wildlife?

“I’m fascinated at the contrast between New Jersey’s really remarkable habitats and ecosystems in the context of our equally remarkable human population density. Generations of pioneering conservationists from past decades have allowed our State’s wildlife to persist even with so many people. I view our generation — and my kids’ — as stewards of that conservation legacy.”

 

 What is your favorite thing to do when you aren’t working?

“I love spending time with my family, such as taking trips with my husband, Mac, and two daughters, as well as time with extended family — Mom, brothers, cousins. I enjoy working with my kids’ Girls Scout troops and helping at their schools.”


Please join us on Wednesday November 30, 2016 from 6:00 – 8:30 p.m. at the Duke Farms’ Coach Barn to honor the contributions that Wendy Walsh, Martha Maxwell-Doyle, and Tanya Sulikowski have made to wildlife in New Jersey.

We are excited to recognize the leadership and inspiration they provide for those working to protect wildlife in New Jersey. Women & Wildlife will also celebrate the timeless and inspiring journeys of wildlife migration in New Jersey and beyond.

 

Wildlife returns to the industrial Newark Bay waterfront

by David Wheeler

Under the sweltering September sun, our team discovers the earth at our fingertips. We ready the manure, topsoil, and mulch, wield the pickax and trowel, and labor the wheelbarrow through the trees and up the slope of a tidal berm.

osprey-silouette-by-blaine

 

We plant 250 native shrubs and 580 native herbaceous plugs. We hammer in nest boxes, install pollinator houses, construct mounds of brush for local and migrating wildlife, and create nesting habitat for northern diamondback terrapin, an at-risk turtle species.

We lose ourselves in nature for the day.

A migrating butterfly flits past leisurely and I look up from the soil to wipe my brow. Suddenly I remember exactly where this newly vibrant natural ecosystem is. Nearly overhead, I can watch never-ending streams of commuters and tractor trailers motor past over one of the busiest bridges in the nation – the Newark Bay Bridge. Just across the bay, I can see heavy industry. Out beyond the fence, more industry – ancient, tireless, modern progress marching forward.

Yet on this morning, and those that follow, we now have ecological progress here as well, in a place that was written off entirely not so long ago. The Newark Bay region has suffered a century and a half of environmental degradation at the hands of industry and unbridled development.

This active industrial site is home to Firmenich Inc., one of the largest manufactures of fragrances in the world. We have transformed the land today to invite wildlife partners to help balance the scales of the region’s damaged ecology.

These partners are vital to our environment, to our health, to the world around us. They are the butterflies and bees, the wasps and beetles, the flies and moths that make up an army of pollinators that in coordinated effort provide humanity with the lungs of our planet. Without these pollinators, native plants could not sink carbon dioxide and impart oxygen to our surroundings, every minute of every day. Without these pollinators, the bread baskets of the world would wither away, no longer filled with grains, fruits, and vegetables.

The natural partnerships don’t stop with the pollinators born forth from meadow creation. These partners extend to migrating songbirds and mighty raptors, small mammals and diamondback terrapins.

“If we give nature an inch, it’s going to take a yard. Give it a chance and nature will return,” says biologist Blaine Rothauser, who is directing the restoration for GZA Environmental. “Wildlife just needs an opportunity.”

heron-by-blaine

Nature’s inspiring return builds upon decades of ecological recovery in the region. Thanks to President Nixon’s Clean Water Act of 1973, the water began to get cleaner. Improving the water quality reanimated the food chain from the bottom up – phyto- and zooplankton, invertebrates and crustaceans reappeared. In turn, a fishery was reborn, which ushered in the return of herons, ibis, osprey, turtles, and even harbor seals – seen sunning on the banks of tidal shores in winter!

Yet much of the land around the water’s edge is still wanting.

“The restoration site is an important buffer habitat to a large portion of undeveloped tidal bay directly adjacent to the Firmenich complex,” says Rothauser. “Today we have 60 people planting a native community of shrubs, trees and plants on a formerly sterile lawn and an unnaturalized earthen berm. It is vital work that makes a real difference.”

The team has also created opportunities for rare species to nest. Above our heads, an osprey platform has been installed, empowering this magnificent fish-eating raptor to continue its recovery along Newark Bay and many other New Jersey waterways, industrial and remote alike.

A barn owl box offers one of our most mysterious nighttime predators the opportunity to set up shop in a beneficial area – where there is no shortage of rabbits and field mice to help control.

Across the pond, a purple martin condominium-like house offers the ample space necessary for these communal swallows to reside, a home base where they can feast on flying insects.

With the first phase of the project almost complete, the second phase will seek to transform the site’s holding ponds into ecologically productive floating wetlands, bringing herons and egrets and other wading birds.

Ultimately, this project is envisioned as one that can be replicated just about anywhere along Newark Bay – or any industrial waterfront for that matter. All it takes is the willingness to look at a site’s land from a different perspective – and in so doing, to understand that the ecological benefits of bringing back many wildlife species aren’t negated by losing economic tradeoffs.

Instead they can mean parallel economic benefits. Natural pest control. Fewer landscaping and pesticide costs. Increased employee morale and productivity, with a newfound opportunity to recharge body and mind with a rejuvenating break outside, enjoying natural beauty and the engagement of your senses.

New Jersey has long served as a primary engine for America’s industry and commerce – and in return has often been derided as the “Which exit?” land of nothing but turnpike and smokestacks. The Meadowlands just to the north of here bore the brunt of that reputation, yet in recent decades has made a mind-blowing ecological recovery to become a wildlife – and ecotourism – destination.

The waters flow south from the Meadowlands along the Hackensack and Passaic Rivers, and they come together in the Newark Bay. Now, that next wave of wildlife recovery and habitat restoration has arrived just downstream – along the Newark Bay waterfront.

For wildlife, it’s where the action is.

Halloween Without Bats

By Stephanie Feigin, Wildlife Ecologist

This Halloween, while you are with friends and family celebrating a spooky evening of fun, I ask you to take a moment and think about one more thing – Halloween without bats. I want you to think about bats today not as the spooky creatures of the night that some people normally think of them as, but as incredible mammals that are invaluable to our ecosystem. In New Jersey, all of our 9 bat species are insectivores. They can eat thousands of insects in one night, protecting our crops and forests from insect destruction, and they pollinate many important foods that we love. A study published in Science magazine estimates that bats’ insect-eating services may be worth as much as $53 billion to US agriculture alone.

Despite the many environmental and economic benefits bats provide, bat populations around the world are still declining. Bats face many threats, including habitat loss and destruction, human persecution, wind energy development, and White-Nose Syndrome.

Devastatingly, we have lost over 6 million bats nationwide due to the spread of White Nose Syndrome (WNS) – a disease caused by a cold-loving fungus called Pseudogymnoascus destructans or Pd. It attacks hibernating bats, disturbing them during hibernation when the bats’ immune response is low, and prevents them from conserving enough stored energy to survive until spring. WNS also causes dehydration and unrest as well as severe wing damage that can prevent bats from flying. Much is still unknown about White-nose syndrome, its spread, and its consequences. The federal government, states, several universities, and organizations like ours are working hard to track and understand this disease.

In New Jersey, about 50,000 bats were killed by WNS in the first year (2009) – and we now estimate over 60 tons of mosquitoes and other night-flying insects go undevoured each year from loss of bats. Though bats are one of the most beneficial animals to humans they are still poorly understood and underappreciated, which is why today I ask you to think of them in a new light. Today, think about bats for all of the wonderful benefits they provide, think of them as amazing animals that work hard at night to protect our ecosystems, because we need to make a change.

To protect the bats we still have, it is important that people understand the stress these bats are under. It is important that we re-think how we view bats, remove the spooky stigmas that surround them and appreciate their importance to us. So today, think about bats think about how important they are, how badly we need to protect them and how scary a world without bats would be.
