Duck Nest Success And Predators In North Dakota, South Dakota, And Montana: The Central Flyway Study, Michael A. Johnson, Thomas C. Hinz, Thomas L. Kuck

Great Plains Wildlife Damage Control Workshop Proceedings

Data on duck nest success and the distribution and abundance of nest predators were obtained from nine study areas in North Dakota, South Dakota and Montana. Success rates were extremely low due to predation and duck production over much of the region may be insufficient to maintain populations.

Prairie Dog Overpopulation: Value Judgement Or Ecological Reality?, Kirsten Krueger

Great Plains Wildlife Damage Control Workshop Proceedings

The subject of prairie dog (Cynomys ludovicianus) overpopulation is complex, and judgements of overpopulation may not be based on prairie dog population size or density. Caughley's (1981) model of animal overpopulation is applied here to prairie dogs to clarify the basis for a judgement of overpopulation in each of several cases. There are ecological components to all such cases, but a purely ecological judgement of overpopulation requires much more information than is currently available. However, defensible management of prairie dog systems is a goal, and time-honored but flawed assumptions are never an adequate substitute for results derived from thorough, scientific …

Results Of A Bird Damage Survey Of Kansas Feedlots, Charles D. Lee

Great Plains Wildlife Damage Control Workshop Proceedings

A mail survey was conducted in the Fall of 1986 of 196 licensed Kansas feedlots to get a better idea of the extent as well as kinds of wildlife damage they experience. The results of this survey are being used in designing a research project to help feedlot operators cope with bird damage.

Legislative Review Of Prairie Dog Statutes, Lyndell Peterson

Great Plains Wildlife Damage Control Workshop Proceedings

The legislature is a modern version of a system that allows us to get along and bring our values together, sort them out, and establish ground rules under which we function. As we imbalance nature in our favor and apply our values through the legislature and congress, one prevailing value is that most of us will go to war for our right to own property. Yet there are times when our point of view functions in such a way that we say this process should provide us authority and power over somebody else's property as long as nobody exercises that …

Should Ducks Be Frightened?, William K. Pfeifer, Steven D. Fairaizl

Great Plains Wildlife Damage Control Workshop Proceedings

The most common method of resolving waterfowl depredations to small grains is to scare ducks using mechanical scare devices or pyrotechnics. Scaring techniques, however, cause waterfowl to damage, by trampling, up to twice the amount of grain consumed. Conditions such as weather, harvest stage, cultural techniques, farm equipment, length of damage season, availability of alternative feeding sites, and waterfowl population could combine to increase trampling losses. These conditions should be evaluated to determine if large scale scaring projects may actually increase damages to small grains.

Policy And Goals In The Private Sector, Rick Warhurst

Great Plains Wildlife Damage Control Workshop Proceedings

Today I am supposed to talk about policy and goals for predator management and control to enhance waterfowl production in the private sector. The private sector includes a wide array of interests. Each of you probably has a particular opinion. You have already observed some different thinking, some different languages, in reference to predator control from previous panel members. If you extrapolate that over the whole United States population, which would be the private sector, it would include a wide array of interests and thoughts.

Laboratory Trial Of Chlorophacinone As A Prairie Dog Toxicant, Daryl D. Fisher, Robert M. Timm

Great Plains Wildlife Damage Control Workshop Proceedings

A laboratory trial was conducted to investigate the efficacy and secondary toxicity of chlorophaoinone oats as a prairie dog toxicant. Bait containing 0.0025% chlorophacinone killed 29 of 31 prairie dogs when offered in 25 gram amounts daily for 6 days. Five of 6 domestic ferrets died of anticoagulant poisoning when fed H of these toxicant-kil led prairie dogs over 8 days. Chlorophacinone may not be an acceptable prairie dog toxicant due to this potential secondary hazard.

Bullsnake Predation On Waterfowl Nests On Valentine National Wildlife Refuge, Nebraska, Scott S. Glup, Leonard L. Mcdaniel

Great Plains Wildlife Damage Control Workshop Proceedings

Bullsnake (Pituophis melanoleucus) predation on upland nesting ducks was monitored on Valentine National Wildlife Refuge (NWR) from 1982-86. The fate of 1,999 duck nests of 9 species was observed under different treatments of land use and control of potential nest predators. Maximum potential levels of bullsnake depredation are masked by nest destruction by mammalian species; bullsnake nest depredation rates were >65% where mammalian predators were controlled, >40% without predator control and <4.0% where both mammalian and reptilian predators were controlled and/or excluded. Duck nest densities were dramatically increased where predator control was accomplished in undisturbed nesting cover.

Policy And Goals On National Wildlife Refuges, Len Mcdaniels

Great Plains Wildlife Damage Control Workshop Proceedings

The information that I am to present is the National Wildlife Refuge policy in regard to predator control. One of the goals of the National Wildlife Refuge System is to perpetuate the migratory bird resource. Since 1983 the policy of animal control on National Wildlife Refuges is to assess the effects of predation on breeding ducks; and, if predators are compromising waterfowl production, controls may be implemented. However, in reading the manual for policy on predator control, I found there are a lot of "hoops" to jump through before starting a predator control program.

Politics, Prairie Dogs, And The Sportsman, John Sharps

Great Plains Wildlife Damage Control Workshop Proceedings

I would like to speak to you today about potential economic and biological values of prairie dogs. When I refer to prairie dogs throughout my talk, I'm referring only to the prairie dogs on the National Grasslands Systems in western South Dakota. Prairie dogs have great economic potential to sportsmen and the general public and also act as ecosystem regulators to grassland plant and animal communities, and as such, could enhance both potentials if managed differently.

Predator Management To Increase Duck Nest Success, Harold A. Doty, Anthony J. Rondeau

Great Plains Wildlife Damage Control Workshop Proceedings

Operational programs of seasonal predator management to increase duck production may be economically feasible. Mammalian predators of nesting ducks and their eggs were reduced in numbers on selected areas of west central Minnesota during the nesting seasons 1982-86. Where predators were removed, nest success averaged 30% while nest success on nearby untreated habitat was 10%.

Why Do Possums Survive Aerial Poisoning Operations?, D. R. Morgan, C. L. Batcheler, J. A. Peters

Vertebrate Pest Conference Proceedings: 12th (1986)

Major causes of failure of aerial poisoning operations against possums identified were: sublethal toxic loading, undersize sublethal baits, nonlearned behavioral aversion to 1080, and failure to encounter bait. Dislike of bait was not a major cause of failure.

Progress has been made towards solving these problems, but failure to encounter bait remains a likely major reason for possums surviving aerial poisoning. Improvements in the aerial sowing of bait are essential if the full benefit of this progress is to be realized.

Polinices Predation Patterns And Mercenaria Morphology Models, John A. Commito

Environmental Studies Faculty Publications

DeAngelis et al. (1985) have described a model of the evolutionary response of bivalve prey to size-selective naticid snail predation. The model analyzed "the allocation of bivalve energy among reproduction, overall growth in size, and supplementary growth in shell thickness" (p. 818). Using parameter values for Polinices duplicatus as the predator and Mercenaria mercenaria as the prey, the model predicted three optimal strategies for bivalves faced with naticid predation: (1) delayed reproduction with energy diverted into rapid growth in order to reach a size refuge; (2) early reproduction, possibly with some extra shell thickness; and (3) greatly increased shell thickness …

Pesticide Use And Toxicology In Relation To Wildlife: Organophosphorus And Carbamate , Compounds, Gregory J. Smith, U.S. Department Of The Interior, Fish And Wildlife Service

All U.S. Government Documents (Utah Regional Depository)

The use of organophosphorus and carbamate pesticides has increased markedly during the past two decades. Currently, more than 100 different organophosphorus and carbamate chemicals are registered as the active ingredients in thousands of different pesticide products in the United States. More than 160 million acre-treatments of these pesticides are estimated to be applied to agricultural crops and forests each year. Clearly, these two groups of chemicals constitute a major portion of all pesticides used today. Organophosphorus and carbamate compounds have histories dating back long before their use as pesticides. Carbamates were developed during investigation of "ordeal" poisons used in Africa …

Integrated Pest Management On Rangeland: State Of The Art In The Sagebrush Ecosystem, Jerome A. Onsager, Usda, Agricultural Research Service

All U.S. Government Documents (Utah Regional Depository)

Several sagebrush communities represent optimum levels of negative development plant productivity for certain peculiar sites, and therefore should be managed for their preservation. Other sagebrush communities may be profitably modified to favor forage species that are more palatable to domestic livestock. Modification techniques can range from subtle (i.e., grazing strategies) to tracematic (i.e., brush removal and revegetation), and an associated spectrum of management tactics are described. Interrelationships between and problems associated with management of forage resources, management of weeds, and management of insects (including grasshoppers, black grass bugs, and beneficial insects) are discussed. Economical analyses, the role of modeling as …

A Prototype For Quality: Bryce Canyon National Park Interpretive Prospectus, 1987, United States Department Of The Interior, National Park Service

Parks and Reserves

To ensure maximum coordination of message delivery, personal service efforts should be orchestrated as a result of annual (winter season) planning sessions involving TW Services, Bryce/Zion Trail Rides, and park personnel. Such planning should coordinate general summer season schedules, brainstorm new program ideas and service proposals, and establish procedures for monitoring and evaluation. This is also an opportunity to identify high priority messages regarding resources, events, new services, and park management pertinent in the coming season; in this manner, emphases for seasonal training are established.

Fisheries Report No 76 - The Australian Herring Fishery In Western Australia, 1973 - 1985, Michael H. Walker, Diane P. Clarke

Fisheries Research Reports

The Australian herring (Arripis georgianus) ts a pelagic, largely marine, species which is relatively abundant in the south western waters of Western Australia. It is a close relative of the Australian salmon with a similar life history and habits which includes migrating for the purpose of spawning. The Australian herring is keenly sought both as a food fish and for bait. This report documents the fishery for this species as it has developed during the period 1973 to 1985.

An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry

Technical Bulletins

The inventory and condition survey of rangelands in the Carnarvon Basin, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1980 and 1982, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers …
