NASBR 2016 Keynote Message from Merlin Tuttle Source: By Paula: October 22 2016 Merlin’s Keynote Message at the 46th Annual Symposium of the North American Society for Bat Research By Merlin Tuttle 22/10/2016 -------------------------------------- “Merlin provided perspective on bat conservation progress in America over the 46 years since annual meetings of North American bat researchers began in 1970. At that time most Americans had been led to believe that bats were little more than disease carrying mostly rabid vermin and frightened citizens were spending tens of millions of dollars annually hiring pest control companies to poison bats in buildings.” Our early research objectives included studies documenting that scare campaigns by those profiting from human fear were themselves posing the most serious threats to public health. We put fear in perspective showing that bats in fact have one of our planet’s finest records of living safely with people documented

numerous values of bats gradually overcame historic misperceptions and gained protection for thousands of critical bat roosting habitats. As interest and appreciation of bats increased our group grew from 42 to over 400 participants and we can now take great pride in many accomplishments. Hundreds of thousands of Straw-colored fruit bats Eidolon helvum beginning their evening departure from a city park in Ivory Coast Africa. Cities often provide the only homes safe from commercial hunters who sell these bats for human food. Despite large numbers having been eaten and having lived in close association with humans throughout recorded history they have caused no documented disease outbreaks. The remarkable safety record of bats worldwide casts grave doubt on recent speculation of their being dangerous carriers of deadly diseases. Nevertheless several alarming reversals are once again posing serious threats to bats and the ecosystems and economies they protect. In North America alone hundreds of thousands of bats are now being killed annually at carelessly operated wind energy facilities that are rapidly expanding. Unfortunately too many companies are ignoring recent studies documenting how to dramatically reduce kills at minimal cost. Merlin stressed the importance of partnering with concerned industry officials to rank companies based on their “green” records in avoiding needless harm to bats. He reported willingness of “green energy” advisers to inform investors noting that through such collaboration there is still hope for an improved future. Merlin next focused on the extreme threat of white-nose syndrome WNS an introduced fungal disease that has killed millions of cave-dwelling bats. Despite our best efforts it has spread rapidly from coast to coast. He emphasized that it is now here to stay. It cannot be stopped or slowed and we are unlikely to find a safe and effectively applicable cure. There is no longer justification for disturbing bat hibernation sites no matter how

well intended just to check on WNS spread or impacts. Winter disturbance forces additional loss of already depleted energy reserves and could become the proverbial straw that broke the camel’s back. The good news is that small apparently resistant remnants of even the most seriously threatened species are beginning to show signs of recovery. And given careful protection there is hope for successful rebuilding of resistant populations as appears to have already occurred in Europe and Asia. The need for improved use of non-invasive active-season monitoring of status trends was also stressed. Encouraging evidence indicates that even the little brown myotis Myotis lucifugus one of the species most decimated by WNS is beginning to successfully reproduce and rebuild apparently resistant populations as appears to have already occurred in Europe and Asia. It’s time to give these tiny remnants the best possible protection from winter disturbance. Merlin’s greatest concern focused on the alarmingly pervasive resurgence of greatly exaggerated speculation about the potential for bats to serve as reservoirs for so-called “emerging diseases.” He emphasized the exceptionally poor science backing these already widely accepted claims. There have been too many attempts to prove rather than test hypotheses as well as cases of misinterpreting isolated correlations as causation while ignoring large amounts of contradictory evidence. He also showed examples of subsequently discredited speculation published in leading journals warning of their potential to reverse decades of conservation progress not to mention the credibility of science itself.

He next emphasized the power of research documenting bat contributions to human well-being and the need to communicate such findings effectively to the public at large. He reminded young colleagues that most of the world’s more than 1300 bat species have barely been studied beyond being taxonomically described and

predicted exceptional opportunities for exciting discoveries. He especially mentioned potential discoveries enhancing pest control ecoservices disease prevention and human longevity. “Finally Merlin provided an example of the economic impact of restoring just one large bat colony in Thailand. Guano production for fertilizer rose from 12500 in 1981 to 132000 annually by 2002 and local control of rice pests is now valued at 300000 annually. He challenged colleagues to become more actively engaged in sharing their findings from human-relevant research beyond their immediate colleagues and offered free use of his large photo collection in support of such efforts.” Despite early public health warnings of high disease risks especially rabies just by posting small signs asking visitors not to handle the bats millions of tourists have watched the spectacular emergences of over a million free-tailed bats from the Congress Avenue Bridge in Austin Texas for more than 35 years without a single instance of anyone contracting a disease from a bat. The now beloved and protected bats consume tons of crop and yard pests nightly and bring millions of tourist dollars each summer. Worldwide bats have one of our planet’s finest safety records when it comes to living safely with people. ……………………………………………..
