Agenda: Water As A Public Resource: Emerging Rights And Obligations, University Of Colorado Boulder. Natural Resources Law Center

Water as a Public Resource: Emerging Rights and Obligations (Summer Conference, June 1-3)

Conference organizers and/or faculty included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches, and Charles F. Wilkinson.

This conference focused on the legal rights associated with a broad range of public uses and interests in water including recreation, fish and wildlife protection, and water quality. Evolving legal areas such as the public trust doctrine, instream flow laws, federal reserved rights, and wetlands protection were discussed.

Water as a Public Resource: Emerging Rights and Obligations considered the extension of the public trust doctrine to areas previously not covered by this concept, as well as developments in …

Importance Of Attractant Qualities For Improving A New Coyote Delivery System, Steven M. Ebbert, Daniel B. Fagre Apr 1987

Importance Of Attractant Qualities For Improving A New Coyote Delivery System, Steven M. Ebbert, Daniel B. Fagre

Great Plains Wildlife Damage Control Workshop Proceedings

Changes in effectiveness and nontarget species selectivity of a new system for delivering ingestible substances to coyotes (Canis latrans) were examined by systematically varying odor type and quantity used to attract coyotes to the device. The new delivery system's efficacy was comparable to the M-44 in our tests in south Texas. A synthetic lure improved the effectiveness of the delivery system when applied in amounts of 0.10 cc or 0.50 cc. Varying odor type did not increase the incidence of desirable coyote behavior, such as biting, but did increase rates of visitation.


Control Of Ecosystem Processes By Prairie Dogs And Other Grassland Herbivores, James K. Detling, April D. Whicker Apr 1987

Control Of Ecosystem Processes By Prairie Dogs And Other Grassland Herbivores, James K. Detling, April D. Whicker

Great Plains Wildlife Damage Control Workshop Proceedings

Black-tailed prairie dogs in the mixed-grass prairie at Wind Cave National Park, South Dakota, create habitat patches characterized by altered species composition, lower standing crops of plants, but higher forage quality. Native wildlife species such as bison, pronghorn, and elk preferentially feed on these prairie dog colonies and likely derive nutritional benefits from doing so.


The Lure Crop Alternative, Steven D. Fairaizl, William K. Pfeifer Apr 1987

The Lure Crop Alternative, Steven D. Fairaizl, William K. Pfeifer

Great Plains Wildlife Damage Control Workshop Proceedings

Lure crops are proposed as an alternative to scaring waterfowl. The lure crop works on the principle of permitting waterfowl to feed undisturbed for the duration of the damage season in an unharvested field of their choice thereby utilizing trampled grain. Waterfowl from adjacent areas are encouraged to use the lure crop through the use of scaring devices placed in protected fields. General criteria for implementation of a lure crop project and specific criteria for lure crop purchases are presented. Factors contributing to a successful lure crop and problems which reduced lure crop effectiveness are identified. Benefit/cost analysis of lure …


Aerial Hunting Takes Sheep-Killing Coyotes In Western Montana, Guy Connolly, Bart W. O'Gara Apr 1987

Aerial Hunting Takes Sheep-Killing Coyotes In Western Montana, Guy Connolly, Bart W. O'Gara

Great Plains Wildlife Damage Control Workshop Proceedings

This paper reports limited data to document that depredating coyotes were shot from a helicopter in western Montana in 1976. Coyotes marked themselves by puncturing diphacinone-filled collars on the necks of sheep they attacked. Subsequently, 11 coyotes were shot from a helicopter on 3 ranches where collared sheep had been attacked. Six coyotes contained diphacinone and thus were confirmed as having recently attacked or fed on collared sheep.


Overwater Nesting By Ducks: A Review And Management Implications, Stephen H. Bouffard, David E. Sharp, Carol C. Evans Apr 1987

Overwater Nesting By Ducks: A Review And Management Implications, Stephen H. Bouffard, David E. Sharp, Carol C. Evans

Great Plains Wildlife Damage Control Workshop Proceedings

Nest success of overwater duck nests is generally higher than nests in upland sites. A review of the literature indicated that the major factors limiting success of overwater nests were fluctuating water levels, nest parasitism, predation, and human disturbance. Regional patterns of the occurrence of these factors could not be discerned. General management guidelines for improved recruitment and reduced nesting female mortality are suggested.


Efficacy Of Deferred Grazing In Reducing Prairie Dog Reinfestation Rates, Kelly A. Cable, Robert M. Timm Apr 1987

Efficacy Of Deferred Grazing In Reducing Prairie Dog Reinfestation Rates, Kelly A. Cable, Robert M. Timm

Great Plains Wildlife Damage Control Workshop Proceedings

Population growth of black-tailed prairie dogs (Cynomys ludovicianus) was studied in 1985 and 1986 at 20 prairie dog towns on short- and mixed-grass rangeland in western Nebraska, to determine the efficacy of 2 years deferred (May 1 - Sept. 1) grazing in reducing population growth rates following population reduction. In 1985, population growth measures on deferred sites were not significantly different from grazed sites, perhaps due to drought conditions. In 1986, natality and population growth (% increase in animals) were significantly lower on deferred sites than on sites grazed by livestock. Deferred sites studied both years showed significant …


A Statistical Model Of Expansion In A Colony Of Black-Tailed Prairie Dogs, R. P. Cincotta, D. W. Uresk, R. M. Hansen Apr 1987

A Statistical Model Of Expansion In A Colony Of Black-Tailed Prairie Dogs, R. P. Cincotta, D. W. Uresk, R. M. Hansen

Great Plains Wildlife Damage Control Workshop Proceedings

To predict prairie dog establishment in areas adjacent to a colony we sampled: (1) VISIBILITY through the vegetation using a target, (2) POPULATION DENSITY at the colony edge, (3) DISTANCE from the edge to the potential site of settlement, and (4) % FORB COVER. Step-wise regression analysis indicated that establishment of prairie dogs in adjacent prairie was most likely to occur when an area was near a densely populated colony edge with high visibility through the vegetation.
