Role And Responsibilities Of Agencies For Wildlife Damage Control, Hal S. Atkinson Jr.

Wildlife Damage Management Conference

The wildlife resources of the State belong to the people of the state as a whole. The Wildlife Resources Commission is charged with the stewardship of these resources and is empowered by general statute to promulgate those regulations deemed necessary to accomplish this charge.

Landowner Tolerance Of Beavers: Implications For Damage Management And Control, Ken G. Purdy, Daniel J. Decker, Richard A. Malecki, John C. Proud

Wildlife Damage Management Conference

Management of beaver (Castor canadensis) populations can be an effective way to create wetlands while at the same time producing a valued recreational and furbearer resource. Optimizing beaver populations for such a dual objective, however, requires careful integration of biological and sociological considerations in management planning. Knowledge of beaver population dynamics by itself is insufficient for sound management; human tolerance data also must be included in management decisions to reduce the potential of encountering problems that could impede the attainment of beaver-wetlands management objectives. Expansion of beaver into new areas often may be constrained by managers' perceptions of …

Wildlife Damage Control And The Wildlife Society, Thomas M. Franklin

Wildlife Damage Management Conference

Wildlife damage control is recognized by The Wildlife Society as an essential and responsible segment of the wildlife profession. At least since 1959, Society committees have addressed elements of wildlife damage control (although wildlife damage control was not always the specific term used).

The Wildlife Society Council first approved an "Animal Damage Control" position statement in 1968. In March 1985, Council updated and renamed it "Wildlife Damage Control" to emphasize our positive approach to this important segment of wildlife management. The official position statement was published in The Wildlifer (May-June 1985) and is reprinted below.

Future Of Wildlife Damage Control And The Cooperative Extension Service, Peter T. Bromley

Wildlife Damage Management Conference

The driving forces which determine the role of the Cooperative Extension Service in wildlife damage control are (1) the demand for information by the public, (2) the degree of support for programs at the national level, and (3) the level of professionalism exhibited by Cooperative Extension Agents and subject matter Specialists. Analysis of several trends suggests that the Cooperative Extension Service role in Wildlife Damage Control will increase in coming years. The movement of urban people into rural settings will create greater demands for wildlife damage control information. Likewise, the expansion of wildlife population into urban and suburban environments due …

Animal Damage Control And The Endangered Species Act, Warren T. Parker

Wildlife Damage Management Conference

The premise of the Endangered Species Act is that all wildlife are valuable natural resources and the extinction of species in the name of progress must be halted. To achieve this end, Congress requires all Federal agencies to consult with the Fish and Wildlife Service when any of their programs or projects affect a listed endangered or threatened species. Problems of special interest to this conference are those that project an endangered or threatened species in direct conflict with man.

What You Wanted To Know About All You Ever Heard Concerning Snake Repellents, Gary J. San Julian, David K. Woodward

Wildlife Damage Management Conference

Have you ever heard about a way to keep snakes away from your house? Many people in North Carolina have been told by their elders of various ways to repel snakes. When we first started working on this problem in North Carolina, we were amazed at the number of "home remedies" that people believed would protect their property from snakes; and we began to keep a record of these remedies. In 1981, a grant from the Pesticide Impact Assessment Program allowed us to begin to test some of these remedies to determine their value.

An Investigation Of Techniques Used To Discourage Rebuilding Of Beaver Dams Demolished By Explosives, James M. Dyer, Charles E. Rowell

Wildlife Damage Management Conference

One hundred seventeen beaver dams were partially or wholly demolished with explosives from April through August between 1982 and 1984. These dams were of two types; shallow water dams found in areas of flat terrain, and deep water dams found in major creek channels or in areas of hilly terrain. Following demolition, various treatments were applied to the dam sites to try to retard rebuilding. Our conclusions are that deep water dams can be removed more effectively than shallow water dams and that late summer removals were rebuilt less frequently than early and midsummer removals. Also, certain types of repellents …

Utilizing A Computerized Fish And Wildlife Information System To Solve Animal Damage Control Problems, Jefferson L. Waldon, Charles T. Cushwa, Peter T. Bromley

Wildlife Damage Management Conference

Animal damage control professionals are faced with the monumental task of absorbing an enormous amount of literature about animal species. For example, one person cannot become an expert on all facets of dozens of species, much less the 1000 or more fish, reptiles, amphibians, mammals, and birds that fall under the wildlifer's jurisdiction. An important new aid to the wildlife damage control specialist is the computerized fish and wildlife information system (CFWIS). A CFWIS is a tool for systematically compiling and managing information about animal species which reside in a state. Cushwa and Kopf (1984) summarized the development of state …

Computer Assisted Extension Program On Ground Squirrel Control, Terrell P. Salmon, Donald L. Lancaster, Leanne Lasarow

Wildlife Damage Management Conference

Computers have become common place in virtually all phases of agriculture. Most individuals have access to micro-computers and the once apparent intimidation about using them is rapidly disappearing. Because of increased availability and public acceptance, it's no surprise that many Extension programs are using computers as an important component of their educational package. Recently, several computer models have been developed to assist Extension personnel and others in demonstrating proper wildlife damage control decision-making. We have developed such a model which is used to: 1) present ground squirrel control information to the grower, 2) take user (grower) input on production, yields, …

Birds In Hangars- A Messy Problem, Albert E. Bivings Iv

Wildlife Damage Management Conference

Pest birds in hangars and similar man-made structures pose specific health hazards as well as nuisance and corrosion problems. While lethal control or a scaring program may be the best technique for some locations, neither address the long-term problem of the basic attractiveness of these structures to birds. The best long-term solution usually is to exclude the birds with permanently installed plastic or nylon netting. Several methods to accomplish this are discussed.

The Role Of The Indiana Division Of Fish And Wildlife In Wildlife Damage Control, Glenn Lange

Wildlife Damage Management Conference

As defined by state statue, the Division of Fish and Wildlife is responsible for the protection, reproduction, care, management, survival, and regulation of all wildlife populations. By law, the Division must take a leading role in solving wildlife damage problems when they occur.

Role And Responsibilities Of Agencies For Wildlife Damage Control - An Overview, James E. Miller

Wildlife Damage Management Conference

"A well balanced wildlife management program includes research, the acquisition of land, the development of habitat, the careful regulation of hunting or harvest, the protection of certain species, the enforcement of laws -- and -- the control of animal depredations. Though necessary, this is among the least popular and most controversial of the wildlife management functions. It is, nevertheless, one of the activities which a responsible agency must undertake." This statement is a direct quote from the International Association of Fish and Wildlife Agencies' (IAFWA) Position Paper on Animal Damage Control (1981).

Closing Remarks, F. Eugene Hester

Wildlife Damage Management Conference

I am glad to be here to present the closing remarks before such as group of professionals who represent the many agencies and individuals who daily perform the delicate task of resolving animal damage conflicts. The segment of wildlife management that you represent is perhaps the most difficult to accomplish in view of existing public opinion and involvement.

Histoplasmosis And Its Impact On Blackbird/Starling Roost Management, A. R. Stickley Jr., R. J. Weeks

Wildlife Damage Management Conference

Histoplasrnosis is a common and sometimes serious fungal disease that primarily affects the lungs, but can also involve other parts of the human body. The disease is characterized by 3 major forms: acute pulmonary, chronic cavitary, and disseminated histoplasmosis.Two fungicides are effective in treatment of the disease, but serious side effects often result. The occurrence of the fungus, Histoplasma capsulatum, is associated with large quantities of bird and bat excreta that have come in contact with soil. Roost sites must generally be occupied by birds for at least 3 years before soil conditions are conducive to its growth. Once established, …

Removal Of Nesting Starlings With Drc-1339, Douglas I. Hall

Wildlife Damage Management Conference

DRC-1339-treated crickets (Gryllus sp.) were utilized in an attempt to remove starlings (Sturnus vulgaris) nesting and rearing young in the aircraft hangars at the Little Rock Air Center, Little Rock, Pulaski County, Arkansas. Bait ratio of 1 treated to 5 untreated crickets was used. They were placed under airport night lights where foraging birds naturally gathered to feed on insects attracted to these lights. Adult starlings consumed the crickets as well as fed them to their young. Lethal control was achieved on both age classes of bird. Field test results show promise for the development of …

Usda Forest Service Role In Wildlife Damage Control, Hugh C. Black

Wildlife Damage Management Conference

Wildlife damage control is an important objective of resource management on the 191 million acres of National Forest System (NFS) lands administered by the USDA Forest Service. Policy on wildlife damage control is based on the USDA Policy on Fish and Wildlife (Secretary's Memorandum 9500-3, July 1983). The objective of wildlife damage control is to reduce damage and loss by wildlife on all NFS lands to levels consistent with management objectives. Control measures are only undertaken when and where necessary to realize wildlife management objectives and to prevent serious damage to public or private property and natural resources. Because of …

Final Draft Report: Economic Policy Options For Utah Agriculture, Donald L. Snyder, Jay C. Andersen, Deevon Bailey, E. Bruce Godfrey

Economic Research Institute Study Papers

As a general rule, economists seldom advocate policy options. They prefer to discuss advantages and disadvantages. Primarily, this is because of an inherent belief that the market does provide for an efficient allocation of goods and services for those participating in that particular market. However, it is widely recognized that the market will not allocate efficiently if certain impediments exist. Furthermore, in situations where the market cannot reflect true social costs and benefits, some corrective actions may be required.

Concentrations Of Uranium Isotopes In Uranium Millers' And Miners' Tissues, United States Nuclear Regulatory Commission

Health

The alpha-emitting isotopes of uranium and thorium were determined in the lungs of 14 former uranium miners and in soft tissues and bones of three miners and two millers. These radionuclides were also determined in soft tissues and bones of seven normal controls. The average concentrations in pCi/kg wet weight in 17 former miners' lungs are as follows: U-238, 75; U-234, 80; Th-230, 79. Concentrations of each nuclide ranged from 2 to 325 pCi/kg. The average ratio of U-238/U-234 ws 0.92, ranging from 0.64 to 1.06. The mean ratio of Th-230/U-234 was 1.04, ranging from 0.33 to 3.54. The near …

Plants

Maintaining natural resources on western military installations has received increasing attention in recent years. Of special interest are training ranges where the environmental impact of tracked and wheeled vehicles is significant. Revegetation and soil stabilization on the arid and semi-arid regions of these western installations require special techniques. This report identifies key plant species that may be useful to installation land managers seeking to maintain or rehabilitate training land in these areas. The plant species are described in terms of their regional and environmental adaptations, limitations, uses, establishment requirements, and availability. In addition, recommendations for short- and long-term revegetation efforts …

The Market Organization Of Utah Agriculture, Donald L. Snyder, Terrence F. Glover, Jay C. Andersen

Economic Research Institute Study Papers

Food marketing may be thought of as the connecting link between the production of basic agriucltural products and delivery of finished, processed food commodities to the consumer. It may be defined as the performance of all business activities involved in the flow of food products and services from the point of initial agriucltural production until they are in the hands of consumers.

The Potential For Agricultural Development In Utah, Donald L. Snyder, Terrence F. Glover

Economic Research Institute Study Papers

Many factors contribute to the expansion of existing industries and/or the development of new ones. First, a shift in population densities can produce a shift in production areas given that transportation is not costless. Second, a significant change in local, regional, or state business climate can induce certain businesses to change locations. Third, a discovery or sudden availability of certain types of resources can also bring about such a change. Fourth, changes in market structure or industrial organization often result in production shifts. Fifth, enterprising producers often serve as catylists to encourage the development of new enterprises in a particular …

Contribution Of Scanning Electron Microscopy And Associated Analytical Techniques To The Study Of Atherosclerotic Disease, R. Laschi

Scanning Electron Microscopy

Human carotid atheroma has been examined by scanning electron microscopy (SEM) utilizing both secondary and backscattered electron detectors and transmission electron microscopy (TEM) both at conventional and high voltage.

Different cytochemical techniques have been used to map elastic fibers, proteoglycans, calcium, non esterified cholesterol. By immunocytochemistry the distribution of factor VIII related antigen and actin has been studied.

With SEM it was possible to detect aspects of carotid plaques not appreciated when using other conventional techniques. With TEM some modifications of the structural and/or functional features of connective tissue macromolecules have been observed. The occurrence of anomalous collagen has been …

Scanning And Transmission Electron Microscopy Of Bacterial Attachment To Mucosal Surfaces With Particular Reference To The Human Fallopian Tube, Morris D. Cooper, Christine Jeffery

Scanning Electron Microscopy

Neisseria gonorrhoeae and Chlamydia trachomatis are the common bacteria isolated from bacterial cervicitis and are the leading etiological agents for pelvic inflammatory disease. Neisseria gonorrhoeae cause infection of the mucosa of fallopian tubes in organ culture by (a) attaching to microvilli of nonciliated cells, (b) phagocytosis by these cells, (c) transport across and exocytosis from the epithelial cells. In contrast the Chlamydia attach to the epithelial surface without apparent ligand binding and are taken into the cytoplasm of the epithelial cell. Exocytosis of Chlamydia is into the tubal lumen and not into the subepithelial spaces. The ciliated epithelial cells of …

Morphological Observations Of Mineralizing Pericardium Cardiac Grafts, P. Frasca, J. W. Buchanan, R. Z. Soriano, J. M. Dunn, L. Marmon, J. Melbin, S. J. Buchanan, E. E. Golub, I. M. Shapiro

Scanning Electron Microscopy

Pericardial patch grafts were implanted in the hearts of young sheep for periods ranging from two to 120 days. Explants seven to 21 days old revealed the formation of a "pseudoneointima" (PNI) on the blood contacting surface of the pericardium. The PNI was more heavily mineralized than the pericardium. Mineralization was most intense on the blood contacting surface of the PNI and on the chamber surface of the pericardium. After three weeks of implantation, the PNI was much thinner and was organized into a thin fibrous capsule without any signs of mineralization. In the pericardium, mineral deposits were seen in …

Scanning Electron Microscopy Studies Of Staphylococcal Adherence To Heart Valve Endothelial Cells In Organ Culture: An In Vitro Model Of Acute Endocarditis, Morris D. Cooper, Christine Jeffery, Debra L. Gall, Andrew S. Anderson

Scanning Electron Microscopy

Organ cultures of human heart valves were used as a model to study the initial pathobiology of acute infective bacterial endocarditis. We used Staphylococcus aureus isolated from a case of infective endocarditis to infect the in vitro culture of the heart valves. Using scanning electron microscopy, we assessed the initial damage, attachment to and invasion of the endothelial cell layer by staphylococci. Our results indicate there is initial damage to the endothelium prior to observation of staphylococci attaching to the endothelial cell. By 12 h post infection, there is significant attachment and damage. At 24 h after infection, destruction of …

Quantitation Of Scanning Electron Microscopic Urinary Cytology, M. Cano, R. B. Wilson, S. M. Cohen

Scanning Electron Microscopy

Using scanning electron microscopy (SEM), differences in cell surface morphology are identifiable between normal urothelium and malignant urothelia including the presence of pleomorphic microvilli (PMV). PMV have been reported in carcinomas of the urinary bladder, and they appear early in the pathogenesis of these tumors in animal models. Preliminary studies in our laboratory and others' demonstrated similar changes in tissue and cytologic specimens from patients with bladder cancer. We observed and evaluated normal and neoplastic cells of the human bladder by SEM in a preliminary assessment of surface topography with regard to tumor growth, grade, and stage. However, while these …

Simulation With Pharmacological Agents Of Radiation Damage To Small Intestinal Villi, M. Indran, F. C. Boyle, K. E. Carr

Scanning Electron Microscopy

Irradiation induces damage to intestinal villi, resulting in a progressive decline in villous height and changes in topography. Gamma and neutron radiation are reported to cause changes in the structure of smooth muscle and nerve twigs of the intestinal wall. It is possible, therefore, that villous collapse may be due partly to changes in the underlying stromal elements as a result of damage to nerve or muscle.

To test this hypothesis, mice were treated with the drug reserpine which is known to affect the neural control of intestinal smooth muscle function and the small intestine was examined for topographical and …

Interactions Between Spermatozoa And The Crypts, Cilia, And Mucus Of The Cervix In The Ewe, William P. Wergin

Scanning Electron Microscopy

In ruminants, minor cervical folds, commonly called crypts, temporarily store spermatozoa for a short interval of time between insemination and fertilization. However, the mechanism by which spermatozoa are transported to these crypts and subsequently to the uterus is not known. To study this problem, cervical tissue, which was removed from ewes that were naturally inseminated by rams at estrus, was examined with the scanning electron microscope to determine the physical associations that occur between the spermatozoa and the structural features of the cervix. The study indicates that the spermatozoa generally are not oriented parallel to the longitudinal axis of the …

The Effect Of High Energy (Hze) Particle Radiation (40ar) On Aging Parameters Of Mouse Hippocampus And Retina, D. E. Philpott, W. Sapp, J. Miquel, K. Kato, R. Corbett, J. Stevenson, S. Black, K. A. Lindseth, E. V. Benton

Scanning Electron Microscopy

Eight month old C57BL6 mice were exposed (head only) to 0.5 rad or 50 rads of Argon particles at the Lawrence Berkeley Radiation Facility, CA. Neuromotor performance was assessed monthly for six months beginning twelve weeks post-irradiation using a ''string test". The decline in motor performance was dose-related and none of the animals was able to complete the task after four months of testing. Morphological changes were monitored six and twelve months post-irradiation by light and electron microscopy. The synaptic density in the CA-1 area of the hippocampus decreased six and twelve months after irradiation. The decrease after twelve months …
