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. -
Walrus: Wildlife Notebook Series
Walrus Pacific walruses (Odobenus rosmarus divergens) belong to a group of marine mammals known as pinnipeds (pinna, a wing or fin; and pedis, a foot), this group also includes the seals and sea lions. Walruses are most commonly found in relatively shallow water areas, close to ice or land. In Alaska, their geographic range includes the Bering and Chukchi Seas. General description: Walruses are the largest pinnipeds in arctic and subarctic seas. The genus name Odobenus means “tooth-walker.” Walrus tusks are elongated upper canine teeth both males and females have tusks. Walruses and sea lions can rotate their hind flippers forward to ‘walk’ on them but seals cannot and drag their hind limbs when moving on land or ice. Walruses are large pinnipeds and adult males (bulls) may weigh 2 tons and the females (cows) may exceed 1 ton. Bulls can be identified by their larger size, broad muzzle, heavy tusks, and the presence of numerous large bumps, called bosses, on the neck and shoulders. Food habits: Walruses feed mainly on invertebrates such as clams and snails found on the bottom of the relatively shallow and rich Bering and Chukchi Seas. Walruses find food by brushing the sea-bottom with their broad, flat muzzles using their sensitive whiskers to locate food items. Tusks are not used for finding food. Walruses feed using suction formed by pulling back a thick piston-like tongue inside their narrow mouth. Walruses are able to suck the soft parts out of the shells; few hard parts are ingested. The rejected shells of clams and snails can be found on the sea floor near the furrows made during feeding. -
56. Otariidae and Phocidae
FAUNA of AUSTRALIA 56. OTARIIDAE AND PHOCIDAE JUDITH E. KING 1 Australian Sea-lion–Neophoca cinerea [G. Ross] Southern Elephant Seal–Mirounga leonina [G. Ross] Ross Seal, with pup–Ommatophoca rossii [J. Libke] Australian Sea-lion–Neophoca cinerea [G. Ross] Weddell Seal–Leptonychotes weddellii [P. Shaughnessy] New Zealand Fur-seal–Arctocephalus forsteri [G. Ross] Crab-eater Seal–Lobodon carcinophagus [P. Shaughnessy] 56. OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig. -
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. -

THE SUBSISTENCE HARVEST and USE of STELLER SEA LIONS in ALASKA by Terry L Haynes and Craig Mishler Technical Paper No
THE SUBSISTENCE HARVEST AND USE OF STELLER SEA LIONS IN ALASKA by Terry L Haynes and Craig Mishler Technical Paper No. 198 This research was partially supported by ANILCA Federal Aid funds administered through the U.S. Fish and Wildlife Service, Anchorage, Alaska, SG-1-9 Alaska Department of Fish and Game Division of Subsistence Juneau, Alaska July 1991 EEO STATEMENT The Alaska Department of Fish and Game operates all of its public programs and activities free from discrimination on the basis of race, igion, color, national origin, age, sex, or handicap Because the de partment receives federal funding, any person who believes he or she has been discriminated against should write to: O.E.O. U.S. Department of the Interior Washington, D.C. 20240 i ABSTRACT Subsequent to the classification of the Steller sea lion as a threatened species in 1990, a Sea Lion Recovery Team was created and charged with preparing a population recovery plan. This report examines the historical literature on subsistence uses, reviews Native oral traditions, and summarizes the limited amount of available information on contemporary harvests and uses of sea lions over a wide range of 25 coastal Alaskan communities. The report is designed to assist in creation of a recovery plan sensitive to subsistence uses. Further research and data needs are identified for consideration in the development of a long-range sea lion management plan. Various strategies of hunting sea lions are described, along with hunting technologies, methods of butchering sea lions, and traditional ways of cooking and serving them. Evidence gathered from prehistoric sites is summarized, and the pervasive symbolic role of Steller sea lions in Koniag and Aleut folktales, folk songs, and folk beliefs is examined in some detail. -
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. -
THE PACIFIC WALRUS by KARL W
332 Oryx THE PACIFIC WALRUS By KARL W. KENYON During recent years there have been repeated reports of extravagant exploitation of the walrus by Eskimos and these have been strengthened by aerial observation of many headless carcasses on beaches of the Bering Sea. So in 1958 the United States Fish and Wildlife Service decided upon an inquiry into the Pacific Walrus, and its hunting and utilization by Eskimo in the Bering Sea region. Biologists from the Department of Health, Education and Welfare, and the Alaska Department of Fish and Game co- operated in the work. Studies were conducted on St. Lawrence Island by Dr. Francis H. Fay and Mr. Averill Thayer, on Little Diomede Island by the late Mr. Stanley S. Fredericksen and the author, and on Round Island of the Walrus Islands in Bristol Bay, by Dr. Fay, Mr. James W. Brooks and the author. Dr. John L. Buckley of the Fish and Wildlife Service counted walruses on the ice of the northern Bering Sea from the air. The Eskimo hunters freely gave us their co-operation and good will, and this alone made the study possible. The economic incentive to exploit pinnipeds for oil and hides decreased after the chaotic slaughter of the eighteenth and nineteenth centuries when many species were seriously depleted. During the present century those which have continued to yield valuable products, such as elephant seals (Mirounga) and fur seals (Callorhinus and Arctocephalus), have been conserved. The Pacific walrus occupies a unique position in that the demand for its ivory, both carved and unworked, or raw, has increased in recent years, whereas measures introduced for conservation of the walrus have not yet been effective.
