The Extirpation And Re-Establishment Of Coyotes In The Edwards Plateau Of Texas, Gary Nunley
The Extirpation And Re-Establishment Of Coyotes In The Edwards Plateau Of Texas, Gary Nunley
Great Plains Wildlife Damage Control Workshop Proceedings
In the early 1900's organized predator control was initiated to remove coyotes and wolves from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920's, many of the inner Edwards Plateau counties were considered to be practically free of coyotes (Canis latrans) and wolves (Canis lupus, Canis rufus). The 1950's found coyotes and wolves extirpated from most of the Edwards Plateau. After a coyote population irruption in the late 1950's, coyotes began to re-establish themselves on the periphery of the Plateau. This encroachment process continued throughout …
Aggressive Behavior Of Mississippi Kites In Suburban Areas, Berkeley R. Peterson, Charles S. Brown
Aggressive Behavior Of Mississippi Kites In Suburban Areas, Berkeley R. Peterson, Charles S. Brown
Great Plains Wildlife Damage Control Workshop Proceedings
The Mississippi Kite is a small diurnal bird of prey which nests throughout the southern Great Plains Its aggressive behavior during nesting has created problems for residents in suburban areas. The removal of the nest and relocation of the eggs and young will end the attacks by the parent birds. The eggs are incubated and the resulting young, as well as other young removed from problem nests, are then placed in foster nests in more remote areas. Preliminary results indicated this will be a very successful way of dealing with the young of problem kites and is an effective way …
Black-Tailed Prairie Dog Management On The Northern Great Plains New Challenges And Opportunities, Greg L. Schenbeck
Black-Tailed Prairie Dog Management On The Northern Great Plains New Challenges And Opportunities, Greg L. Schenbeck
Great Plains Wildlife Damage Control Workshop Proceedings
Implications of new information and several recent developments to the management of black-tailed prairie dogs (cynomys ludovicianusl on the northern plains are discussed. Of primary importance is the need to conduct management programs that are as cost--effective as possible and responsive to the concerns of private land interests. Research findings indicate that cost-effectiveness can be improved by combining rodenticide use with changes in livestock grazing practices to reduce habitat suitability for prairie dogs. Other research suggests that reduced concentrations of Compound 1080 for prairie dog control warrants continued scientific evaluation. If reduced concentrations of 1080 could be used effectively and …

Beaver Problems Associated Wtth Conservation Activities, Ed M. Schwille
Great Plains Wildlife Damage Control Workshop Proceedings
As far back as 1935, the U.S. Department of Agriculture, Soil Conservation Service (SCS) began providing technical assistance to private landowners to build ponds and small lakes. To date in Texas, over 500,00 structures of this type have been built. During the 1940'x, the SCS started construction of Watershed Protection and Flood Control Impoundments in Texas. These flood prevention structures number about 1900. Other programs have brought about construction of over 16,000 grade stabilization structures (GSS) for erosion control. Numerous ponds and lakes have been built without any help from the SCS over the years. All of these impoundments store …

Opening Address: The Importance Of Wildlife Damage Control In Texas, Zerle L. Carpenter
Opening Address: The Importance Of Wildlife Damage Control In Texas, Zerle L. Carpenter
Great Plains Wildlife Damage Control Workshop Proceedings
Let me first indicate that I have been interested in wildlife damage control programs for a good part of my life. My first experience, at the tender age of 6 years, was hard to accept when coyotes killed my 4-H pig. The importance of wildlife damage control has been clear to me since that time. Unfortunately, the importance of control is not often clear to those people who have not directly experienced wildlife damage. On my first arrival in Texas in 1962. coyote populations were increasing in the state. At that time I was given the charge from the Texas …

Wildlife Diseases And Human Health, Keith A. Clark
Great Plains Wildlife Damage Control Workshop Proceedings
Zoonoses (singular, zoonosis) are diseases transmissible from animals to man. There are over 200 such diseases; many are harbored by wildlife reservoirs. A reservoir may be defined as a source which maintains the presence of a disease in an ecosystem. Wildlife-associated "zoonoses found in Texas include rabies, plague, tularemia, Rocky Mountain spotted fever, Lyme disease, leptospirosis, relapsing fever, typhus, and leprosy. The mission of the Zoonosis Control Division of the Texas Department of Health is to protect the health of Texas citizens against zoonoses. Surveillance programs for various diseases are an integral part of the overall control programs, which include …
The Effect Of Dietary Protein And Feed Size On The Assimilation Efficiency Of Starlings And Blackbirds, Daniel J. Twedt
The Effect Of Dietary Protein And Feed Size On The Assimilation Efficiency Of Starlings And Blackbirds, Daniel J. Twedt
Great Plains Wildlife Damage Control Workshop Proceedings
Starlings (Sturnus vulgaris) were fed 3 feed sizes and 3 protein levels of swine feeds to determine metabolizable energy and assimilation efficiency. Metabolizable energy (12 kcal/g of diet consumed) and assimilation efficiency (3296 of gross energy intake) were independent of feed size. A 46% crude protein diet was 5196 assimilated and yielded more energy per gram of diet consumed than a 2196 crude protein diet which was only 35% assimilated. Starlings failed to maintain their body weight on a cracked corn diet containing 14% crude protein. Feeding behaviors of starlings due to their assimilation efficiencies are discussed and contrasted with …

Reported Beaver Damage And Control Methods Used In Texas, Jan E. Loven
Reported Beaver Damage And Control Methods Used In Texas, Jan E. Loven
Great Plains Wildlife Damage Control Workshop Proceedings
Beaver have greatly increased their range in Texas due to restocking and construction of man-made water impoundments. Damages can generally be categorized into dike and impoundment damage, tree damage, and flooding or other damages. These total $9,326,541 for the fiscal years 1983, 1984, and 1985. Methods used to remove beaver include: conibear traps, leg-hold traps, snares, spotlighting, and technical consultation. Live traps are seldom used. Total number of beaver taken for fiscal years 1983, 1984 and 1985 is 5,158.
Incidence And Significance Of Giardia Lamblia (Lambl ) In Texas Beaver Populations, Robert Beach, William F. Mcculloch
Incidence And Significance Of Giardia Lamblia (Lambl ) In Texas Beaver Populations, Robert Beach, William F. Mcculloch
Great Plains Wildlife Damage Control Workshop Proceedings
The Giardia lamblia (Lambl) protozoan is not a recently discovered parasite. It was. in fact, one of the first organisms viewed and described by Antony van Leeuwenhoek (1681) as he designed the first usable microscope. Leeuwenhoek found this organism in a sample of his own diarrhetic stool and thus he constitutes the first confirmed case of human giardiasis. His finding represents proof of glardiasis’ close association with man for many years. Leeuwenhoek’s discovery of the giardial trophozoite was not elaborated on for some 178 years, however, as it was not until 1859 that Wilhelm D. Lambl systematically described the organism …

The Use Of Fixed Wing Aircraft In Predator Control, Larry D. Vetterman
Great Plains Wildlife Damage Control Workshop Proceedings
Aerial hunting was first used in a professional predator control program in 1942. The most popular aircraft used by animal damage control agencies is the Piper PA-18. Proper training of flight crews is of utmost importance for a successful aerial operation. Fixed wing hunting is restricted to relatively open areas and flat terrain. Aerial hunting is an excellent control method where livestock losses are severe and immediate control is needed.

Big Game Depredations And Damage Compensation In Wyoming, John R. Demaree
Great Plains Wildlife Damage Control Workshop Proceedings
The Wyoming Game and Fish Department is responsible for controlling depredations by big game, trophy game, and game birds. Under certain guidelines landowners can submit a claim to the department for compensation from wildlife depredations. Measures used by department personnel to prevent wildlife damage are the use of scare devices, harassment techniques, repellents, fencing, trapping, issuing of kill permits, and modifying hunting seasons. In evaluating the damage to estimate monetary losses, sources of information used include AUM's, consumptive rates, fecal analysis, enclosures, production records, and necropsies. In terms of depredation compensation, the most costly species to the department over the …

Current Status And Potential Registrations Of Compound 1080 And Strychnine For Rodent Control, Lyle A. Crosby
Great Plains Wildlife Damage Control Workshop Proceedings
On December 1, 1976, the Environmental Protection Agency applied Section 6 of the Federal Insecticide. Fungicide, and Rodenticide Act, "Administrative Review", in determining that the use of products containing strychnine, for above ground application to control several rodent species, met specific cancellation criteria outlined in 40 CFR 162.11. Position Document 4 (the final Agency decision), published on September 30, 1983, proposed to cancel registrations of strychnine products for above ground use to control prairie dogs and required label modification for confined use on ground squirrels. The final decision was challenged by several parties who requested a formal hearing which was …

Alligator Nuisance Control Program In Texas: Problem And Process, Lee Ann Johnson, David S. Lobpries, Bruce G. Thompson
Great Plains Wildlife Damage Control Workshop Proceedings
Following protection of the American alligator (Alligator mississippiensis) in Texas beginning in 1969, alligator numbers have increased rapidly (Patter 1981). Such population increases led to the federal reclassification of the species from Endangered to Threatened--Similarity of Appearance in 1983 in Texas (Bowman 1983). Similarity of appearance classification acknowledges the biological security of the Texas alligator population and the need for specific harvest controls to ensure that the conservation of similar appearing species is not compromised. As alligator populations recovered, nuisance complaints directed to the Texas Parks and Wildlife Department (T'PWD) accelerated as well. Complaints now number several hundred annually and …

Furbearer Management And The Steel Foothold Trap, Samuel B. Linhart
Furbearer Management And The Steel Foothold Trap, Samuel B. Linhart
Great Plains Wildlife Damage Control Workshop Proceedings
The trapping of furbearers, particularly with steel foothold traps, has become more and more controversial. The controversy is significant because the steel trap is considered the most versatile of the various methods available for capturing furbearers (Payne 1980). Whether traps are used to reduce livestock losses by predators or to harvest furs, the controversy has gained the attention and interest of various social factions, each with differing beliefs, attitudes, and philosophies.

Deer Damage Prevention Efforts In Pennsylvania, Jack M. Payee, William L. Palmer
Great Plains Wildlife Damage Control Workshop Proceedings
Research at the Pennsylvania State University was directed towards finding effective repellents to control damage caused by white-tailed deer (Odocoileus virginianus) and to develop a low-cost alternative to the traditional 2.4 m woven wire barrier fence, considered to be deer-proof, but too expensive for mgt agricultural uses. Fourteen repellents were screened and 9 were found to be more effective than the others. These 9 repellents were further investigated under semi-field conditions and only 1 repellent was found to be consistent in reducing deer feeding. A vertical electric deer fence was effective in excluding deer at field sites containing alfalfa, small …
Preliminary Studies On The Feasibility Of Urban Rabies Control, Richard C. Rosatte
Preliminary Studies On The Feasibility Of Urban Rabies Control, Richard C. Rosatte
Great Plains Wildlife Damage Control Workshop Proceedings
A preliminary investigation was initiated in 1984 to determine the feasibility of an urban rabies control strategy which involved capturing, vaccinating and releasing skunks and raccoons in metropolitan Toronto, Ontario. Results indicate urban skunks and raccoons are utilizing extremely small home ranges and their movements are not extensive. Trapping data suggested a large proportion of the population of skunks and raccoons in the study area were captured during the first 4 nights of trapping. Capture data also indicated the presence of new animals in the study areas between trapping periods. The 3 study areas, which differed in human land-use classification, …
The Use Of Population Reduction As A Technique To Combat Rabies In Alberta, Canada, Richard C. Rosatte
The Use Of Population Reduction As A Technique To Combat Rabies In Alberta, Canada, Richard C. Rosatte
Great Plains Wildlife Damage Control Workshop Proceedings
Control of rabies by reducing the density of potential vectors has been a controversial matter. Only 2 outbreaks of rabies in Europe are likely to have been completely eradicated by control, 1 in Dijon, France, in 1923, and the other in Corsica in 1943 (MacDonald 1980). Schnurrenberger et aL (1964) apparently controlled an outbreak of rabies in striped skunks (Mephitis mephitis) in Ohio by gassing dens and through the use of poison. An invasion of red fox (Vulpes vulpesl rabies in southern Jutland from Demark was initially halted by a gassing and poisoning campaign. However, in Great Britian, despite the …
