Wildlife In Texas: Marketing Potential And The Significance Of Wildlife Damage, Milo J. Shult
Great Plains Wildlife Damage Control Workshop Proceedings
This is a challenging topic to discuss, and I would first like to review some things which are unique to Texas with respect to wildlife populations. These concern the importance of wildlife from a commodity standpoint Then I would like to delve into some areas which tend to be a little more philosophical and focus on the impacts of total wildlife management, including wildlife damage control. Historically in our nation, wildlife has had ups and downs; there are a number of success stories in terms of management but also some obvious failures. I would like to be positive today concerning …
Current Status And Potential Registrations Of Compound 1080 And Strychnine For Rodent Control, Lyle A. Crosby
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 …

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 500,000 structures of this type have been built. During the 1940's, the SCS started construction of Watershed Protection and Flood Control Impoundments in Texas. These flood prevention structures number about 1,900. 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 …

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.
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, …

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.

Efficacy And Farmer Acceptance Of Nonlethal Control Of Blackbird Depredations To Small Grain Crops, Albert E. Bivings
Efficacy And Farmer Acceptance Of Nonlethal Control Of Blackbird Depredations To Small Grain Crops, Albert E. Bivings
Great Plains Wildlife Damage Control Workshop Proceedings
In 1980, Congress responded to complaints of migratory bird damage to grain crops, principally rice, with added funding for enhanced Animal Damage Control (ADC) programs in Arkansas and Louisiana. This resulted in the establishment of an office in Stuttgart, Arkansas and a similar office in Crowley, Louisiana. Enabling legislation specifically directs the principal focus to be on rice/blackbird conflicts. This paper will present a review of the problems addressed in Arkansas, techniques utilized and the author's assessment of their efficacy and acceptability.

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 erruption in the late 1950's, coyotes began to re-establish themselves on the periphery of the Plateau. This encroachment process continued throughout …
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 …

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 Britain, despite the …

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.
Big Game Depredations And Damage Compensation In Wyoming, John R. Demaree
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 …

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 …

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.
