Evaluating The Gas Cartridge For Coyotes In Controlling Badgers, Craig A. Ramey
Evaluating The Gas Cartridge For Coyotes In Controlling Badgers, Craig A. Ramey
Wildlife Damage Management Conference
Efficacy investigations were conducted in Pampa, TX to evaluate the use of the "GAS CARTRIDGE FOR COYOTES: (Canis latrans) for controlling problem badgers (Taxidea taxus) in burrows. This coyote cartridge with two active ingredients (sodium nitrate and charcoal), produces high concentrations of carbon monoxide when burned and is effective in controlling coyotes in dens. Badgers were live-trapped, immobilized, and equipped with mortality-indicating radio transmitters prior to their release. Movements were monitored for a minimum of 12 days prior to each initial efficacy test and for at least 3 days in follow up tests for survivors. Only occupied …
Impact Of Clearcut Size On White-Tailed Deer Use And Tree Regeneration, James W. Akins, Edwin D. Michael
Impact Of Clearcut Size On White-Tailed Deer Use And Tree Regeneration, James W. Akins, Edwin D. Michael
Wildlife Damage Management Conference
Northeastern forests have experienced regeneration delays and/or failures due to browsing by whitetailed deer (Odocoileus virginianus). Investigations were made in north-central West Virginia to determine if the size of clearcut is correlated with degree of deer browsing, regeneration of shrubs and trees, and percent ground cover by various herbaceous plants. Tree seedlings, woody shrubs, and herbaceous ground cover were recorded in September 1992 and August 1993 on 16, 1-year old clearcuts, ranging in size from 0.8 to 0.2 ha. Woody regeneration was categorized by species, origin, browsed or not, and vegetative height class on 25 systematically arranged sampling …
Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr.
Status And Management Of Vole Damage To Horticultural Plantings In North Carolina, Peter T. Bromley, William T. Sullivan Jr.
Wildlife Damage Management Conference
A trapping study in 1979 indicated that voles (Microtus pennsylvanicus and M. pinetorum) were distributed widely in North Carolina. In 1991, Extension Agents with the North Carolina Cooperative Extension Service were surveyed to determine the distribution, nature and severity of vole damage to horticultural plantings, home orchards, and other plantings. Data from the statewide trapping survey and the poll of agents coincided to indicate that voles, particularly pine voles, caused damage from the mountains to the coast. Existing, legal control methods were judged grossly inadequate by agents. Pursuant to the surveys, the North Carolina Pesticide Board and the …

Public Policy Education: An Important Wildlife Management Opportunity, Paul D. Curtis
Wildlife Damage Management Conference
Suburban wildlife management issues are generating heated debate between citizen organizations, elected public officials, and state wildlife management agencies. Decisions are being made by town and county officials which directly impact or supersede state authority for managing resident wildlife. As an example, I will focus this discussion on the white-tailed deer (Odocoileus virginianus) management controversy at Durand Eastman Park, in the greater Rochester metropolitan area, New York.
Deer Damage In Tennessee: Landowner Perceptions And Attitudes, Michael M. King
Deer Damage In Tennessee: Landowner Perceptions And Attitudes, Michael M. King
Wildlife Damage Management Conference
White-tailed deer (Odocoileus virginianus) are an important resource for Tennesseans. They are enjoyed by consumptive and nonconsumptive users alike. Approximately 190,000 hunters pursued deer during the 1992-93 hunting season in Tennessee. They successfully harvested 126,999 deer (Greg Wathen, TWRA Assistant Chief of Wildlife, pers. commun.) and it has been estimated that these hunters would have spent approximately $125 million on goods and services related to deer hunting (Whitehead 1991).

Perceptions And Knowledge Of Alabama Fruit And Vegetable Producers Towards Coyotes, M. Chad Philipp, James B. Armstrong
Perceptions And Knowledge Of Alabama Fruit And Vegetable Producers Towards Coyotes, M. Chad Philipp, James B. Armstrong
Wildlife Damage Management Conference
Members of the Alabama Fruit and Vegetable Producers Association (AFVP) were surveyed in 1992-1993 to assess their attitudes and knowledge of coyotes and the amount of perceived damage caused by coyotes. A mail-back questionnaire was developed and pilot tested. The revised questionnaire was sent to all members (N = 84) of the AFVP; individuals whose main income is the production of fruits and vegetables. Seventy-seven percent (n = 61) of those surveyed returned completed questionnaires. Tests for nonresponse bias were conducted and results showed no significant difference. Attitudes were assessed using a Likert scale where 1 = respondents favoring maximum …

Landowners Perceptions Of Crop Damage From White-Tailed Deer In South Carolina, Webb M. Smathers Jr., Gary R. Stratton, Derrell Shipes
Wildlife Damage Management Conference
Survey respondents reported a definite increase in the population of white-tailed deer (Odocoileus virginianus) in South Carolina. Almost 73% of the producers from a random sample indicated that deer populations have increased over the five year period preceding 1991. With a higher deer population, crop damage from deer became more prevalent, and 72% of the producers indicated having some level of damage. The producers in the sample had mixed feelings about the damage their crops received with 70% indicating that the damage was either negligible or was tolerable in exchange for having deer around. In South Carolina the …
Status Of Alpha-Chloralose And Other Immobilizing/Euthanizing Chemicals Within The Animal Damage Control Program, Paul P. Woronecki, William L. Thomas
Status Of Alpha-Chloralose And Other Immobilizing/Euthanizing Chemicals Within The Animal Damage Control Program, Paul P. Woronecki, William L. Thomas
Wildlife Damage Management Conference
In 1992 the U.S. Department of Agriculture (USDA), Animal and Plant Health Inspection Service, Animal Damage Control (ADC) program was granted approval from the U.S. Food and Drug Administration (FDA), under a continuing Investigational New Animal Drug agreement, to use Alpha-chloralose (A-C) nationwide for capturing nuisance waterfowl, coots, and pigeons. FDA and ADC have imposed several requirements, restrictions and conditions on the operational use of A-C. Training and certification are required to use A-C and other approved immobilizing and euthanizing agents.

Proceedings Of The Fourth Western Black Bear Workshop, United States Department Of The Interior, National Park Service
Proceedings Of The Fourth Western Black Bear Workshop, United States Department Of The Interior, National Park Service
Wildlife Conservation and Management
The status of black bears in North America ranges from pest to threatened. The species appears relatively secure throughout most parts of its range except the southeastern coastal plain; in this region a number of disjunct populations exist on primarily publicly owned lands. Concern over the status of Ursus americanus luteolus led to a petition to list this subspecies under the Endangered Species Act. The Endangered Species Act is arguably the most important wildlife legislation in recent years. However, applying this valuable, but young, untested, and evolving legislation to the black bear subspecies is judged unwarranted and premature because of …

Management of the majority of public rangeland in the Great Basin and Columbia-Snake River Plateau falls under the authority of the Bureau of Land Management. The flora of this land ranges from highly diverse native plant communities to deteriorated lands dominated by exotic annuals. Approximately nine percent of the BLM’s 78 million acres of public land in this region is degraded to such a degree that changes in land management alone will not result in significant improvement. The BLM intends to restore native plant communities on these deteriorated lands, but current revegetation techniques used to establish introduced perennial grasses are …

Operation Of Glen Canyon Dam, Draft Environmental Impact Statement, United States Department Of The Interior
All U.S. Government Documents (Utah Regional Depository)
This draft environmental impact statement (EIS) analyzes the impacts of operations from 1963 to 1990 (baseline conditions) and alternative operations of Glen Canyon Dam on downstream environmental and cultural resources of Glen and Grand Canyons. Alternative operations evaluated include three that would provide steady flows; three that would provide various levels of fluctuating flows; and two, including no action, that would provide unrestricted fluctuating flows. Additional measures have been combined with the alternative operations, where appropriate, to provide additional resource protection or enhancement. The preferred alternative is the Modified Low Fluctuating Flow Alternative.

Snake River Sockeye Salmon Habitat And Limnological Research, David Teuscher, Doug Taki, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
Historically, thousands of Snake River Sockeye salmon returned to the Sawtooth Valley to spawn. Evermann (1896) reported that the Sawtooth Valley Lakes were teeming with red fish. Bjornn (196~) estimated that 4,360 sockeye returned to Redfish Lake in 1955. These numbers no longer exist. In the 1980's, less than 50 Snake River sockeye salmon survived to spawn (Bowler 1990). Since 19-90, only 13 sockeye have returned. Because of recent declines, the Shoshone-Bannock Tribes (SBT) petitioned the National Marine Fisheries Service (NMFS-) to list Snake River sockeye as endangered. As a result, Snake River sockeye were listed and the Bonneville Power …

Preserves At Risk: An Investigation Of Resource Management Strategies, Implications And Opportunities, R. J. Lilieholm
Elusive Documents
Human activities already threaten the globe's physical and biological systems. Worldwide, species extinction rates are estimated to be one thousand times what they would be in the absence of human activity (Wilson 1988). Raven (1988) estimates that 25% of the world's plant and animal species existing in 1985 may be extinct by 2015, with most extinctions occurring in tropical regions. While these extinction rates are staggering, global warming would greatly accelerate extinction rates that some scientists believe may already exceed those accompanying the decline of the dinosaurs 65 million years ago (Wolf 1987).

Snapshot In Time, Repeat Photography On The Boise National Forest 1870-1992, United States Department Of Agriculture
Forestry
A forest health crisis of unprecedented proportions faced the Boise National Forest in the early years of the 1990's. Six years of drought set the stage for catastrophic outbreaks of insect and disease in the various tree communities of the forest, and wildfires burned hotter and more frequently than at any time in the past. In our often desperate search for ways to moderate the crisis, we turned to the notion of repeat photography to try to understand what happened in the past and how things are different now. We hoped to find some clues that would help shape management …

Revegetation Of Disturbed Semiarid Grassland In Canyonlands National Park, Susan B. Goldberg
Canyonlands Research Bibliography
A grassland restoration project was conducted in Canyonlands National Park on an area recently disturbed due to construction. Two native grasses (Oryzopsis hymenoides and Stipa comata) were seeded with 18 different soil treatments. Stipa density and relative mycorrhizal colonization were measured. None of the soil treatments resulted in significantly greater Stipa density than the control treatment of seeding only plus water. There was very little correlation between Stipa density and mycorrhizal colonization based on the treatments (r2= 0.011 p = 0.05). Three treatments produced 3 to 5 times the VAN colonization as the control including spring cryptobiotic soil crusts, with …
Effects Of Moonlight And Daylight On Hydroacoustic Estimates Of Pelagic Fish Abundance, Chris Luecke, Wayne A. Wurtsbaugh
Effects Of Moonlight And Daylight On Hydroacoustic Estimates Of Pelagic Fish Abundance, Chris Luecke, Wayne A. Wurtsbaugh
Watershed Sciences Faculty Publications
To determine how moonlight and daylight affect hydroacoustic estimates of fish abundance, we used a dual-beam transducer and echo integration to survey pelagic fish (primarily Bonneville ciscoes Prosopium gemmifer) in Bear Lake, Utah and Idaho. During the new moon, the fish were dispersed (not schooling) below the thermocline, chiefly at the depths of 10–20 m. At full moon, they were dispersed but much closer to the bottom, where they were difficult to detect. Acoustic estimates offish density and biomass during full moons were approximately 50% of values derived during new moons. A diel survey during a new moon indicated that …
