Cats And Wildlife: An Animal Welfare Perspective., John Hadidian

Management - General

While there is no question that outdoors cats have an impact on wildlife, the extent and significance of this impact is the subject of considerable debate. The controversy surrounding outdoor cats can be traced back at least a century, with contemporary claims of threats to global biodiversity bringing animal welfare and conservation interests directly into opposition, largely over the means of managing conflicts. The irony in this is that cat defenders and cat detractors generally agree that it is in the best interests of cats that they should be shielded from the vagaries of outdoor life. While there are practical …

What Is A Humane Wildlife Control Service?, John Griffin, Lori Thiele, Pamela Lough, Janet Snyder, Maggie Brasted, John Hadidian

John Hadidian, PhD

In May 2007, The Humane Society of the United States launched a for-fee business called Humane Wildlife Servicessm to engage in wildlife control jobs in the Washington, D.C. metro area. We had several purposes in launching this service. First, we felt it necessary to offer a service to customers in our home base area that allowed them to choose a wildlife removal company that did not trap and relocate, or trap and kill, animals. Second, we wished to directly experience and test the operational and conceptual challenges associated with this sort of service. Third, we wished to develop a model …

“Nuisance” Wildlife Control Trapping: Another Perspective, Brad Gates, John Hadidian, Laura Simon

John Hadidian, PhD

Urban wildlife control is a rapidly growing profession in which many practitioners apparently still come from a recreational or commercial trapping background. Perhaps for that reason, much of the “control” in resolving human-wildlife conflicts in cities and suburbs seems to revolve around the use of lethal traps to eliminate “problem” animals. Although some states allow relocation and most apparently allow for nuisance animals to be released on site, the extent to which these practices occur is little known. Further, the biological impacts of continual trapping cycles on urban wildlife populations remain little known as well. An alternative approach to trapping …

Zoo Animal Welfare: The Human Dimension, Justine Cole, David Fraser

Zoo and Aquarium Animal Populations Collection

Standards and policies intended to safeguard nonhuman animal welfare, whether in zoos, farms, or laboratories, have tended to emphasize features of the physical environment. However, research has now made it clear that very different welfare outcomes are commonly seen in facilities using similar environments or conforming to the same animal welfare requirements. This wide variation is almost certainly due, at least in part, to the important effects of the actions of animal care staff on animal welfare. Drawing mostly on the farm animal literature, we propose that this “human dimension” of animal welfare involves seven components: (1) positive human–animal interaction, …

The Ethics Of Wildlife Control In Humanized Landscapes, John Hadidian, Camilla H. Fox, William S. Lynn

William S. Lynn, PhD

The 21st century is witness to an unprecedented and rapid growth of human settlements, from urban centers to wilderness vacation resorts. Concurrent with this has been the growing tolerance and acceptance of many wild animals and humans for one another. This has created an expanding ‘zone’ of human-animal contacts, some number of which invariably result in conflicts. While the vast majority of our interactions with wild animals are undoubtedly benign, it is the conflict between wildlife and people that draws particularly close attention from the public. Animals viewed as vertebrate “pests” range from the small to the large, the timid …

Wildlife In U.S. Cities: Managing Unwanted Animals, John Hadidian

John Hadidian, PhD

Conflicts between people and wild animals in cities are undoubtedly as old as urban living itself. In the United States it is only of late, however, that many of the species now found in cities have come to live there. The increasing kind and number of human-wildlife conflicts in urbanizing environments makes it a priority that effective and humane means of conflict resolution be found. The urban public wants conflicts with wildlife resolved humanely, but needs to know what the alternative management approaches are, and what ethical standards should guide their use. This paper examines contemporary urban wildlife control in …

Free-Roaming Dogs In Developing Countries: The Benefits Of Capture, Neuter, And Return Programs, Jennifer Jackman, Andrew N. Rowan

Jennifer Jackman, Ph.D.

This chapter provides an overview of animal welfare and public health problems associated with free-roaming dog populations and strategies to resolve these problems. Placing CNR programs in the context of earlier dog and rabies control methods, the chapter explores CNR’s potential to overcome some of the shortcomings of earlier approaches and to improve animal welfare, reduce dog population growth, and prevent the spread of rabies and other canine-transmitted diseases. Constraints and current debates on current implementation of CNR programs are also examined.

Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian

John Hadidian, PhD

The concepts and practices of Integrated Pest Management (IPM) are historically grounded in programs aimed at insects and disease-causing organisms affecting agriculture. When applied to vertebrates, IPM concepts have most often been used in rodent control programs. Still, IPM is a powerful model that arguably can, and should, apply to conflicts with any “pest” or problem-causing organism. It may be time to examine contemporary IPM approaches and their relation to traditional vertebrate pest control more closely. Vertebrate IPM should encompass not only the development of sound and practical steps to shape decision-making and actions, but a dialogue about ethics as …

A Framework To Evaluate Wildlife Feeding In Research, Wildlife Management, Tourism And Recreation, Sara Dubois, David Fraser

Wildlife Population Management Collection

Feeding of wildlife occurs in the context of research, wildlife management, tourism and in opportunistic ways. A review of examples shows that although feeding is often motivated by good intentions, it can lead to problems of public safety and conservation and be detrimental to the welfare of the animals. Examples from British Columbia illustrate the problems (nuisance animal activity, public safety risk) and consequences (culling, translocation) that often arise from uncontrolled feeding. Three features of wildlife feeding can be distinguished: the feasibility of control, the effects on conservation and the effects on animal welfare. An evaluative framework incorporating these three …

Dogs And Dog Control In Developing Countries, J. F. Reese

State of the Animals 2005

The relationship between a community and its dogs is not always entirely positive, and many cultures identify similar problems associated with having dogs in their midst. For example, in South Africa, the Soweto community identified the problems caused by dogs as road accidents, barking and fighting, biting children and killing livestock, and uncontrolled fecal contamination (Beck 2000). Such problems exist in many cultures, throughout the developed and developing worlds.

It is against this background of a wide range of man-dog relationships that dogs in the developing world must be seen and understood. Knowledge about and understanding of the complexity of …

Resolving Conflicts Between People And Canada Geese: The Need For Comprehensive Management Approaches, John Hadidian

Wildlife Population Management Collection

Canada geese have become established and are now numerous enough in many urban and suburban areas that conflicts with humans have become frequent. Although potential threats to human health are often cited as a justification to manage goose populations, currently available science suggests that this is not a serious issue. This leaves the primary concern as one of aesthetics– people do not like having to deal with what can sometimes be copious amounts of goose droppings. Animal welfare interests have questioned the humaneness of different roundup and killing programs, and advocated non-lethal approaches and egg addling. Both approaches currently are …

Is There A Place In The World For Zoos? / Another View Of Zoos, David Hancocks, Richard Farinato

State of the Animals 2001

We human animals make rapid technological and cultural advancements because we have the ability to pass definitive information to succeeding generations. But we also accept too much from the past without challenge. The good, the bad, and the indifferent are muddled together, accumulating in layers that smother each succeeding age. Cultural mores ranging from the silly to the profane, from charming to dangerous, clutter our world. They exist only because, as the British are wont to say, “We have always done things this way.” One very troubling example is the public zoological parks found in almost every city: they are …

Animal Well-Being In Zoos, Conservation Centers And In-Situ Conservation Programs, John Lukas

Zoo and Aquarium Animal Populations Collection

Well-being, as defined in reference to one's welfare, is the condition of happiness, prosperity and good health. In dealing with an animal's well-being, there are two frames of reference to consider. First, biological well-being which encompasses the spacial, social, nutritional, behavioral and reproductive needs of a species. Secondly, cultural well-being of animals concentrating on their perception of happiness, cleanliness, safety and the way the animals are treated by the people who care for them.

In this paper, we are not addressing freedom as a condition of well-being, only happiness, prosperity and good health. Free-ranging wild animals are not free but …

What Do "Wild" And "Captive" Mean For Large Ungulates And Carnivores Now And Into The Twenty-First Century, Michael Hutchins

Zoo and Aquarium Animal Populations Collection

The terms "wild" and "captive" have stimulated considerable debate among academicians, animal protectionists and conservationists. Some argue that animals have a right to freedom and that there is a "moral predis-position" against holding them in zoos (Jamieson, 1985; 1995; Varner and Monroe, 1991). Others argue that modern zoos and their living collections are becoming increasing important to wildlife conservation and science, and that the collective benefits so derived may override this predisposition (Hutchins and Wemmer, 1991; Conway, 1995; Hutchins et al, 1995; Norton, 1995). The purpose of this paper is to explore the concepts of "wild" and "captive" and their …

Wild / Captive And Other Suspect Dualisms, Dale Jamieson

Zoo and Aquarium Animal Populations Collection

Dualisms have had a hard time in recent years. Philosophers used to think that facts and values were distinct, and that philosophy and science were radically different enterprises. While scientists employed empirical methods to discover the way the world happens to be, the job of philosophers was to use conceptual analysis to reveal how the world necessarily is. In the wake of the revolution unleashed by Quine in the early 1950s, philosophers either had to learn some science, find another job, or fight an irredentist action on behalf of conceptual analysis that is mainly of interest only to a few …

Animal Well-Being In The Wild And In Captivity, Stephen Bostock

Zoo and Aquarium Animal Populations Collection

I want to compare wild and captivity. This isn't a straight comparison of good with bad. Animals do suffer in the wild, and they are protected in good captivity. I will fill out the details of this in the following sections, before discussing how captivity can be more benign, whether or not it can ever strictly be regarded as better than life in the wild.

The Wild And The Tame, Juliet Clutton-Brock

Zoo and Aquarium Animal Populations Collection

The Western belief that the world is divided into the "human" and the "natural" stems from the philosophy, first propounded by the ancient Greeks, notably Aristotle, that all living organisms could be placed in a Scale of Nature or Great Chain of Being with "primeval slime" at its base and "Man" at its summit. This belief, which is imbued in Christianity and in all aspects of western civilization, has led to a great divide with "the wild" on one side and "the tame", that is all the animals and plants that are exploited by human, on the other.

Federal Government Assaults Animals On Wildlife Refuges

Close Up Reports

The welfare of America's wildlife and refuges is being sold for economic gain and recreational pleasure to hunters, trappers, and commercial developers. To date, there are 414 refuges composed of over 86 million acres stretching from the Arctic to the Florida Keys and from Maine to American Samoa. Almost all of these refuges have been touched in some way by natural gas exploration, predator control, pesticides, and commercial farming, ranching, and lumber industries. Over one half of all refuges are open to either hunting or trapping...or both.

All laws and regulations concerning activities on wildlife refuges stipulate that there must …

The Role And Responsibility Of Zoos: An Animal Protection Viewpoint, John E. Cooper

Zoos and Aquariums Collection

The aim of this paper is to look at zoological collections from the viewpoint of the animal and, in particular, to draw attention to areas where welfare considerations should be paramount. I do not intend to cover the capture and transportation of zoo animals, although this is obviously of great importance and must be included in any overall consideration of the welfare of zoo animals. In this paper, however, I shall concentrate upon the care of the animal within the zoo environment.

Getting Educated At The Zoo, Nancy Heneson

Zoos and Aquariums Collection

In this issue we present three papers that deal with the subject of the zoo. Although the focal concern of each paper is different and the positions of the authors range from whole-hearted support of the institution to frank skepticism, all express a belief in the potential educational value of zoos. This editorial, however, has a different premise. It is not meant to criticize the other papers, but rather to raise questions from another point of view.

Roadside Zoos Are Not Zoos

Close Up Reports

The HSUS was one of the first national animal welfare organizations to take a long, hard look at all zoos, including roadside menageries. During the last nine years, we have worked intensively, conducting zoo inspections, public education and awareness programs, and developing a working relationship with the professional zoological community as well as U.S. Government agencies charged with the welfare of animals.
