bat hangingThe classic symbol of Halloween, bats are the only true flying mammals. Bats are found all over the earth, except in extreme hot conditions and extreme cold conditions (the poles). There are over 1,000 species of bats in the world (47 in the United States) and, at this time, at least seven of these species are endangered with the possibility of becoming extinct.

A large number of bat deaths each year can be attributed to loss and/or fragmentation of habitat. The conversion of lands, road construction, deforestation, fires, floods and other environmental disasters are examples. Household threats are cats, traps, pesticides and other household chemicals. Loss or scarcity of food and disturbances in nature (both man-made and natural) are also having a negative impact on bats.

White Nose Syndrome (WNS) is a fungus that gets into the hair follicles and the sebaceous glands on the wings, ears, and snouts of hibernating bats, giving them a grey-white appearance and causing ulcers to form on their skin. Since its discovery in 2006, WNS has spread to over 115 caves and mines in the Northeastern United States and five Canadian provinces. As of April 2014, WNS has been found in half of the United States. WNS is spread from bat to bat. It spreads quickly and kills whole bat colonies. WNS is also thought to be transmitted by people who may inadvertently carry the disease from colony to colony on their clothes or other belongings. Signs of the disease are a white fungus on the face, wings or ears; emaciation; difficulty flying; and flying in the daytime. The sores caused by the fungus wake the bats from hibernation, causing them to literally go batty, flying about looking for food and water. Bats have been found dead in clusters at the mouths of caves and mines. Since the first cases of WNS were reported, an estimated 6-7 million bats have died from the disease.

Each year wind turbines kill around 600,000 bats. The problem is a double-edged sword (or turbine blade, as the case may be). Blunt force trauma is one danger. Migrating bats often unintentionally fly into the blades of the turbine. The second danger occurs due to the slight changes in the wind created by the rotating blades of the turbine. This difference of pressure between the bat’s body and the environment, known as barotrauma, causes fatal internal hemorrhaging.

The situation is grave. A bat-tery of approaches is necessary. Protection and management of roosts is important. Care should be taken not to disturb roosting bats. More research needs to be done on bat migration, hibernation, feeding, and breeding habits. We need laws protecting bats. Natural pesticides/insecticides should be used whenever possible. When it is not possible to use natural products, we should reduce the amount and/or frequency of chemicals used.

Dealing with White Nose Syndrome is not as straightforward, however. Cavers and visitors should clean and disinfect their clothing and gear after leaving roost areas, respect cave and mine closures, stay out of places where WNS is known to exist, and report unusual bat behavior.

With a minor adjustment, almost half the bat wind turbine fatalities can be avoided. Most bat turbine deaths happen at low wind speeds because bats can’t fly in high winds. Wind turbines have a “cut speed” of 9 mph. This means that the turbines shut down in any winds that are less than 9 mph. Raising the “cut speed” to 11mph would reduce the fatalities by about 44%.

Maybe the most significant help will come from educating the public about the many ways bats are beneficial. Bats are night pollinators and seed spreaders. Bat poop, “guano,” is a great organic fertilizer. A single bat can eat up to 1,200 insects in one hour, saving farmers – and ultimately the consumer – millions of dollars on insecticides each year. It is always sad when a species is threatened with extinction. Humankind will regret the loss of this important animal if we do not act to save it now.
