Sterilization, Hunting and Culling : Combining Management Approaches for Mitigating Suburban Deer Impacts
Poster Presentation Sterilization, Hunting and Culling: Combining Management Approaches for Mitigating Suburban Deer Impacts J.R. Boulanger University of North Dakota P.D. Curtis and M.L. Ashdown Cornell University ABSTRACT: Based on decades of growing deer impacts on local biodiversity, agricultural damage, and deer-vehicle collisions, in 2007 we implemented an increasingly aggressive suburban deer research and management program on Cornell University lands in Tompkins County, New York. We initially divided Cornell lands into a suburban core campus area (1,100 acres [4.5 km2]) and adjacent outlying areas that contain lands where deer hunting was permitted (~4,000 acres [16.2 km2]). We attempted to reduce deer numbers by surgically sterilizing deer in the core campus zone and increasing harvest of female deer in the hunting zone through an Earn-a-Buck program. During the first 6 years of this study, project staff spayed 96 female deer (>90% of all deer on campus); 69 adult does were marked with radio transmitters to monitor movements and survival. From 2008 to 2013, hunters harvested >600 deer (69–165 each hunting season). By winter 2013, we stabilized the campus deer herd to approximately 100 animals (57 deer/mi2 [22 deer/km2]), a density much higher than project goals (14 deer/mi2). Although we reduced doe and fawn numbers by approximately 38% and 79%, respectfully, this decrease was offset by an increase in bucks that appeared on camera during our population study. In 2014, we supplemented efforts using deer damage permits (DDP) with archery sharpshooting over bait, and collapsible Clover traps with euthanasia by penetrating captive bolt. -
Fast Facts on Canada's Commercial Seal Hunt
Fast Facts on Canada's Commercial Seal Hunt About the Hunt: Canada's commercial seal hunt is the largest slaughter of marine mammals on Earth. In just 10 years, over two million seals have been killed for their fur. This does not include the tens of thousands of injured seals who have died below the ice. 97 percent of the seals killed in the past 10 years have been less than three months of age. Many of these defenseless seals did not yet know how to swim. In 2001, an independent veterinary panel concluded that the seal hunt results in considerable and unacceptable suffering. They noted that in 42 percent of the seals examined there was not enough evidence of cranial injury to even guarantee unconsciousness at the time of skinning. Harp seals rely on sea ice to give birth to and nurse their pups and they need the ice to remain intact until the pups are strong enough to survive in open water. Climate change has caused sea ice to diminish at an alarming rate off Canada’s east coast in the harp seal birthing grounds. Sea ice formation has been well below average for each of the past 15 years, with 2010 having the lowest sea ice formation on record. The Canadian government has estimated up to 100% mortality in harp seal birthing areas when the sea ice did not form or melted too early in the season. Despite this, the Canadian government continues to authorize massive harp seal quotas each year. The Humane Society of the United States takes no issue with subsistence seal hunting by aboriginal people. -

HARRIS" Seal Bounty and Seal Protection Laws in Maine, 1872 to 1972: Historic Perspectives on a Current Controversy- ABSTRACT Modem predator management balances conservation and preservation with the desire to exploit natural resources. Seals (marine predators) engender controversy because seals and humans both consume fish. To understand the foundation of current stakeholder positions concerning seals, we examined the history of seal legislation in Maine from 1872 to 1972, which included two bounty periods as well as limited legal protection. We analyzed the stakeholder interests that influenced Maine legislation and compared them to similar influences at work in a modern context, the Canadian Atlantic Seal Hunt. This history and analysis can provide lessons for seal management elsewhere. I believe seals should be dealt with as you would rats. Norman Olsen, fisherman, Cape Elizabeth, Maine, January 17, 1947' I feel that the [seal] bounty system is extremely and unnecessarily cruel... -
Coexisting with Deer an Advocate’S Guide for Preventing Deer Culls in Your Community
Coexisting with Deer An advocate’s guide for preventing deer culls in your community How to use this toolkit We fight the big fight for all animals, but we can’t do it without your help. This toolkit is designed to add power to your passion; to enable you to be the most effective advocate for the deer in your community. Suburban development has created an environment in which deer thrive; our backyards provide the “edge” habitat (where forest meets field) they prefer, offering ample supply of food and water. Access to abundant resources leads to healthy deer and higher reproductive rates, and as deer populations increase, so too do deer-human conflicts. The result too often is an assumption that there are “too many deer” and a call for lethal control. This toolkit is designed to empower advocates like you to take action, be it against planned lethal measures, or proactively encouraging the adoption of a humane deer management plan. It’s often thought that the voice of a large, national organization is enough, but the voice of a constituent – yours! – is actually the most powerful tool in the fight for the welfare of deer in your community. Local decision-makers want to hear from you, not an outsider. A groundswell of local opposition to a deer cull, or in support of a humane deer management plan, has the greatest impact. This toolkit will provide guidance on how best to voice your opinion, and how to inspire others to do the same. The toolkit is organized as follows: o Learn the issue: Knowing more about the types of conflicts your community may be having with deer can help you better understand how to address them humanely. -

The Use of Animals in Sports
Existence, Breeding, a,nd Rights: The Use of Animals in Sports Donald Scherer Bowling Green State University Against these lines of argument one frequently encounters a certain objection. It is argued that since the animals for fighting, hunting and racing exist only because they have been bred for such human uses, human beings are justified in so treating them. The purpose of this paper is to evaluate this line ofobjection, or to speak more precisely, to evaluate the two distinct objections implicit in this line. For the objection may be either that (l) the present uses of the animals are justified because they are better for the animals than the Standardly, philosophical arguments about the alternative, namely non-existence, or that quality of treatment human beings owe nonhuman animals! rest on two bases. Peter Singer is famous (2) breeding an animal for a purpose gives the for arguing from the capacity of animals to feel pain breeders (transferable) rights over what they to the conclusion that since almost none of the pain have bred. human beings cause animals is necessary, almost none of it is morally justifiable (Singer, 1989, pp. 78-79). I shall pursue these alternatives sequentially. Singer rests his case on the premise that who suffers pain does not affect the badness of the suffering, so The Value of Existence that, without strong justification, the infliction of pain is universally wrong (Ibid., pp. 77-78). Tom Regan is The strength ofthe first form ofthe objection rests on equally famous for his argument that the beliefs and a common intuition comparing the values of existence desires which normal one year-old mammals clearly and non-existence. -

Canada's Commercial Seal Hunt Is Not "Acceptably Humane"
“Throughout my career as a veterinarian, I have seen animals die in slaughterhouses, research labs, and animal shelters, and I can assure you that the cruelty existing in the seal hunt would not be tolerated in these institutions.” Dr. Mary Richardson Animal Care Review Board Solicitor-General of Ontario After observing Canada’s 1995 seal hunt Canada’s Commercial Seal Hunt is Not “Acceptably Humane” Current discussions about animal welfare issues associated with post-mortem examination of skulls.

Humane Society International Worked Around the Globe to Protect Wildlife
Human e Society International Protecting Wildlife Worldwide From deep oceans to tropical rainforests, Humane Society International worked around the globe to protect wildlife. After an investigation re - vealed that the U.S. is the world’s second biggest ivory market after China, eBay Inc. announced that it would no longer sell the commodity on its global websites. This should help reduce the number of elephants slaughtered for their tusks. In partnership with the World Bank and other nongovernmental organ - izations, we helped launch the Global Tiger Initiative, which will use the bank’s considerable influence and funding to save the world’s fast- dwindling population of wild tigers. HSI also contributed to the strength - ening of Peru’s wildlife laws and regulations by cosponsoring a comprehensive study of the illegal wildlife trade in the northern part of the nation. Our marine animal initiatives helped protect whales, dolphins, sharks, and sea turtles, and we worked to secure the listing of polar bears as threatened under the Endangered Species Act.
