Lake Mead Prefertilization Study: Preliminary Nutrient Enhancement Studies In Lake Mead, Richard P. Axler, Larry J. Paulson, Patrick J. Sollberger, Donald H. Baepler, U.S. Bureau Of Reclamation

Publications (WR)

Studies conducted by the University of Nevada-Las Vegas (UNLV), the Nevada Department of Wildlife (NDOW), the Arizona Game and Fish Department (AGFD), The Nevada Division of Environmental Protection (NDEP), and the United States Bureau of Reclamation (USBR) have identified decreased algal production as a major factor involved in the decline of the Lake Mead sport fishery. Phosphorus-laden silt particles in the Colorado River have been sedimenting out in Lake Powell since the completion of Glen Canyon Dam 286 miles upstream in 1963. This sharp decrease in phosphorus loading to Lake Mead (>5000 tons per year) has resulted in decreased …

The Future Of Wildlife Damage Control In An Urban Environment, Gary J. San Julian

Eastern Wildlife Damage Control Conference: 3rd (1987)

As the trend towards urbanization escalates, the United States is rapidly becoming a nation of non-farmers and suburban residents. Consequently, the conflicts between residents and wildlife species are increasing, while the interest in urban wildlife and backyard habitat is growing. These ' trends, coupled with changes in pesticide regulations, a shortage of trained professionals and relic legislation, create a complex and paradoxical situation for residents and professionals in the area of urban wildlife management. The future of wildlife in the urban environment will depend on our ability to convince and educate wildlife managers, citizens and legislators about the need for …

New Uses Of Livestock Guarding Dogs To Reduce Agriculture/Wildlife Conflicts, R. Coppinger, J. Lorenz, Lorna Coppinger

Eastern Wildlife Damage Control Conference: 3rd (1987)

Pilot programs in several states have shown that livestock guarding dogs are 70-80% effective in reducing predation on livestock by wildlife, primarily coyotes. In order to increase that percentage, ineffective dogs were studied and new techniques tested that had the potential of turning problems into successes.

From the population of over 1,000 dogs that has been placed on farms and ranches nationwide during the past ten years under the auspices of the Livestock Dog Project at Hampshire College, data was analyzed for each of the three basic behaviors (trustworthy, attentive, protective) that a good guardian needs to exhibit. A wide …

Closing Remarks, James E. Miller

Eastern Wildlife Damage Control Conference: 3rd (1987)

The need for professionalism in wildlife damage prevention and control is more important today than ever before. It will be even more important in the future as we are faced with increasing interaction between people and their interests which includes many different perceptions about wildlife. Wildlife professionals must change their philosophy regarding communication with the public about both the positive and negative impacts of wildlife. We can no longer afford the luxury, if indeed we ever could, of avoiding people and their perceptions about wildlife. We must provide scientific, biologically and ecologically sound information in a form which the public …

Drc-6749--An Avian Wetting Agent Of Low Aquatic Toxicity, P.W. Lefebvre, T.D. Bills, A.R. Stickley Jr., R.E. Matteson, L.L. Marking

Eastern Wildlife Damage Control Conference: 3rd (1987)

PA-14, the compound presently registered for lethal control of blackbirds and starlings at roosts, is labelled for use only at upland sites. Research was undertaken to identify another wetting agent which might be registered for use at aquatic sites. Of 90 samples received from suppliers, 60 were evaluated for wetting ability in a standard laboratory test. Of these, 10 were chosen for test against an aquatic indicator animal, Daphnia. One of the 10, DRC-6749, a block copolymer, was found significantly low in toxicity, and underwent further aquatic testing against 6 fish and 1 mussel species. Under standard test conditions, no …

Avoiding Controversies That Impede Wildlife Damage Control, B.W. O'Gara

Eastern Wildlife Damage Control Conference: 3rd (1987)

Controversies regarding wildlife damage control often result from incorrect perceptions by the general public or conservation groups. Such controversies can usually be settled to most people's satisfaction by indisputable data. In the past, however, data were often lacking. The ban, by Executive order in 1972, of chemical toxicants for predator control on federal lands and by federal agencies is a good case in point. Indisputable data were not available concerning the level of predation. The only data were derived from questionnaires filled out by livestock producers; Government officials and the public simply would not accept such data as unbiased.

Extension's Perspective Of Federal, State And Private Animal Damage Control Programs, Gary J. San Julian

Eastern Wildlife Damage Control Conference: 3rd (1987)

Extension personnel are in a unique position to observe and to be involved in animal damage control (ADC) programs at the federal, state and private levels. In order to offer educational programs, we must interpret regulations and policies to provide a workable interface between ourselves, other agencies and the public. This is not an easy task in such a sensitive and emotional area.

The lack of uniformity in policies among federal agencies as well as the hazy lines of authority and responsibility for some species makes it hard to provide guidance for our clientele. The growing involvement of the public …

A Method For Assessing Blackbird Damage To Ripening Rice, Robert G. Wright, Keith A. Arnold, Michael O. Way

Eastern Wildlife Damage Control Conference: 3rd (1987)

A method for measuring and mapping the location of blackbird (Icterinae) damage to ripening rice over time was developed and employed in 7 commercial rice fields ranging from 20.6 to 47.4 ha in Matagorda County, Texas, during the 1985 and 1986 growing seasons. Ten evenly-spaced transects were established perpendicular to the longest side of the field and each transect was sampled at pre-determined distances. Transects were subdivided into "edge" (<= 60 m from field border) and "middle" (> 60 m from the field border) strata. The measured percent damage was compared to visual estimates for 3 samplings to assess the accuracy and precision of the latter. Measuring the …

Effectiveness Of Human Hair, Bgr, And A Mixture Of Blood Meal And Peppercorns In Reducing Deer Damage To Young Apple Trees, Michael R. Conover, Gary S. Kania

Eastern Wildlife Damage Control Conference: 3rd (1987)

We evaluated the ability of three repellents [human hair, Big Game Repellent (BGR), and a mixture of blood meal and peppercorns] to reduce deer damage on young apple trees in two Connecticut orchards. Most of the deer damage consisted of winter browsing on dormant apple buds. Little browsing occurred on leaves or buds during the growing season and only a few cases of pre-rut rubbing of trees were observed. In one orchard, buds were browsed during the winter on 52% of the untreated control trees, 45% of the trees sprayed with BGR, and 40% of the trees containing a hair …

State Of The Fisheries Report 1986, Fisheries Department Of Western Australia

Status Reports of the Fisheries and Aquatic Resources

Western Australia continues to be one of the leading fishing States in Australia. The total gross value of fish, crustaceans and molluscs for 1985/86 was $139 million (Table 1) to which may be added the value of the pearl culture industry resulting in a total value of approximately $180 million.

Management Of Native Vegetation On Farmland In The Wheatbelt Of Western Australia, A M. Coates

Resource management technical reports

Clearing in the wheatbelt region of Western Australia has been rapid and extensive. The mapping of remnant vegetation in the shires of Dumbleyung, Lake Grace, Pingelly and Tammin with the use of the most recent aerial photography (1984) demonstrates the extent of clearing especially in the old established farming areas. Only 7 per cent of the Tammin shire had been retained under native vegetation, 10 per cent of the Dumbleyung shire and 14 per cent of the Pingelly shire. In the Lake Grace shire where large areas have only recently been developed for agriculture, approximately 31 per cent had been …

Estimation Of Food Limitation In Daphnia Pulex From Boulder Basin, Lake Mead, Thomas Mark Bartanen

Publications (WR)

In February, 1982 I began a year-long study to determine if growth and reproduction in Daphnia Pulex were limited by the amount of food available in Boulder Basin, Lake Mead. To determine this, I made monthly collections of Daphnia Pulex and natural lake seston from an already established station in Boulder Basin. I cultured the Daphnia Pulex under simulated field conditions in a flow-through feeding apparatus using four different food regimes; 1-natural lake seston filtered through 80 um mesh to remove other zooplankton, 2-lake seston (as above) with an enrichment of 10³ cells-ml^-1 of Chlamydomonas reinhardti, 3-lake …

Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada

Publications (WR)

The Nevada Division of Environmental Protection (DEP) has proposed water-quality standards, applicable to Las Vegas Bay and Lake Mead, for (1) chlorophyll, (2) un-ionized ammonia, and (3) pH.

We have concluded that the proposed standards are unlikely to protect or improve water quality in Lake Mead. The proposed chlorophyll standard:

May harm the fishery. Lakes with more chlorophyll have greater fish production.

Will not improve clarity. Chlorophyll concentrations above 30 ug/1 have little effect on clarity.

Will not protect against scums or dominance by blue-green algae. Lake Mead shows no consistent relationship between chlorophyll and scums or blue-green dominance.

Will …
