To the trained eye, it was clear Kevin Courts and Michael Riff were illegal terrapin harvesters.

The Hatboro, Pennsylvania, men, one shirtless, were parked next to a marsh off Sea Isle Boulevard last July, with six nets and a long pole leaning against their green truck, the state said. A conservation officer who approached them spotted a turtle crawling under the driver’s side seat and found a cooler packed with hatchlings.

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.

Halloween Without Bats

Monday, October 31st, 2016

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.

Atlantic City Electric (ACE), in collaboration with the Conserve Wildlife Foundation of New Jersey, recently held an Avian Protection Educational Event to promote a better understanding of how Atlantic City Electric helps protect birds and other animals, while also helping improve electric service reliability for customers.

ACE environmental scientists Cristina Frank and Mike Garrity detailed the various types of migratory and breeding birds that may perch or nest on power lines, including ospreys, which frequently nest on utility poles. They discussed various types of devices placed on wires and other infrastructure designed to minimize the risk of birds and other wildlife from coming in contact with electric wires and equipment.

“Hundreds of thousands of birds migrate through Cape May County each year,” said Cristina Frank, lead environmental scientist, Atlantic City Electric and head of the company’s Avian Protection Program. “We conduct field studies to determine areas throughout Cape May County and our entire service territory to determine which areas are of the greatest risk to birds and other wildlife.”

ACE senior supervising engineer Ed Kaminski explained how avian protection is an integral part of the design phase before constructing any new infrastructure projects or upgrading existing infrastructure.

“We are in constant communication with our environmental team, and, when necessary, we’ll enhance our infrastructure to minimize the risk to birds while helping reduce the number of related power outages to create a more reliable electric system for customers,” Kaminski said.

Atlantic City Electric recently completed infrastructure enhancements in Cape May, Ocean City and Strathmere, N.J., that addressed risks to avian wildlife. As a result, the company has not seen any bird-related incidents since in these areas.

Also as part of the event, Ben Wurst, a wildlife biologist with the Conserve Wildlife Foundation of New Jersey, discussed the foundation’s role in helping manage and protect ospreys through man-made nesting platforms that provide a safer nesting alternative than utility poles. ACE partners with Conserve Wildlife to identify and address risks to birds throughout its service territory.

Birds routinely use power line poles and towers as perches to establish territorial boundaries, nest, hunt, rest, find shade and feed. Utility poles often provide perching or nesting opportunities in areas where few natural perches or nest sites can be found. If the configuration and location of utility structures are in areas where birds are attracted by favorable habitat or are in a migratory path, the chance of electrocution and/or collisions increase.
