Biodiversity Protection: Implementation and Reform of the Endangered Species Act (Summer Conference, June 9-12)

Conference organizers and/or faculty included University of Colorado School of Law professors Betsy Rieke, David H. Getches, Michael A. Gheleta and Charles F. Wilkinson.

All across the country--in Congress, in state legislatures and in urban and rural communities--people are discussing why we should or should not protect biodiversity and how best to do so. Since the Endangered Species Act is up for reauthorization, a variety of reform proposals are being debated. Speakers--including natural resource scholars, experts from the private and nonprofit sectors, and government officials--will examine the rationale for biodiversity protection, the legal framework of the Endangered Species Act, and …

Effects Of Zebra, Mussel, Dreissena Polymorpha Infestation On Lake Dardanelle Water Quality, Charles J. Gagen, Joseph N. Stoeckel

Arkansas Water Resources Center Technical Reports

Zebra mussels recently invaded southern waterways including the Arkansas River. Large-scale filtration of suspended particulate matter by dense populations could alter reservoir ecosystem function. Furthermore, they attach to hard surfaces, thereby threatening normal operations of artificial structures. We designed this study to provide baseline data prior to establishment of high population levels of zebra mussels in Lake Dardanelle. The characterization of spatial and temporal variability in water quality, zooplankton, phytoplankton, and macrophytes will allow testing of several hypotheses. We sampled zebra mussel veliger and settling juvenile densities and zooplankton densities at four fixed sites and the key water quality variables …

Wildlife As Natural Enemies Of Crop Pests, Ron J. Johnson, James R. Brandle, Natalie Sunderman, Rebecca Fitzmaurice, Nancy A. Beecher, Ronald M. Case, Mary Dix, Linda J. Young, Mark O. Harrell, Robert J. Wright, Laurie Hodges

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

One asset of wildlife to landowners is the potential but understudied role of birds and other species as endemic natural enemies of crop pests. Enhancing such natural enemies as part of sustainable agricultural systems offers promise for maintaining agricultural competitiveness while providing wildlife habitat in intensively farmed areas. The University of Nebraska has established an agroforestry research team to address interdisciplinary questions and outreach associated with this topic. Included are studies of bird, mammal, and insect use of woody and herbaceous corridors and adjacent cropfields in east-central Nebraska. Uncultivated areas needed to sustain natural enemies of crop pests also provide …

Public Issues Education In Natural Resources: Speaking As A Professional, Dave Cleaves, Paul Adams

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

One certainty these days is that public policy will continue to shape the future of forestry. We foresters seem to take what's served up, wishing we had more influence on the ingredients and how they are prepared. We need to assert more leadership in providing forestry knowledge to citizens and decision-makers. However, information delivery is not enough; we need to be involved in the process of policy as well as its content. Technical information and good science will not prevail on their own. We don't have to push a particular option to be effective. We can use our skills and …

Development Of A Forestry, Fish, And Wildlife Center, W. Daniel Edge, Edward Jensen, Nancy Boriack

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Public concerns for stewardship and conservation of biological diversity have caused a reduction in the timber supply in the Pacific Northwest on federal lands. This reduction in the availability of federal timber has resulted in an intensification of management activities on private forest lands. The reduced timber supply has also increased timber prices to the point that many nonindustrial private woodland owners, who previously were not interested in selling timber, have entered the market. This intensification of management activities on the private forest base has resulted in additional increased concerns for fish and wildlife species. Reliable and readily accessible information …

A Tax Incentive To Encourage Wildlife Management: The Texas Example, Charles W. Ramsey

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

A need for external incentives for private landowners to manage their lands for wildlife was identified and has been discussed for many years. As early as 1930, the Committee on Game Policy (Leopold Committee) stressed that incentives for private landowners were crucial to achieving public objectives in wildlife management on private land. Various forms of subsidies, regulations, and taxes have been proposed, tried, modified, perpetuated, or discarded. Incentives or disincentives commonly were directed to specific practices which impact wildlife.

Wildlife in Texas are dependent upon private lands for their existence. Over 90% of the land is privately owned and managed …

Interdisciplinary And Multidisciplinary Public Education By Combining Consensus-Based Planning And Environmental Analysis, Sherman Swanson, Robert Wilson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

In extension, we educate people to improve their lives. In natural resources extension, we educate people to improve life. Resolving issues often does this. In natural resources extension we also resolve issues to educate people.
As educators we steer clear of some issues to avoid the hazards. We may refrain from choosing sides. When we choose sides, we often tarnish the perceived objectivity of our University. Yet issues provide the need for knowledge, the teachable moments, and the set and focus that translates knowledge exposure into learning. When issues involve common resources, shared or conflicting interests, complications from complex or …

Sustainable Channel Catfish Farming: Low Management Production Through Modified Stocking And Feeding Practices, William A. Wurts, Forrest Wynne

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Sustainability has become the recent "buzz-word" in aquaculture and agriculture. As Claude Boyd indicated in San Diego (Aquaculture '95), aquaculture is not truly sustainable because aquaculture relies on external feed, chemical, and energy inputs. The United States Farm Bill of 1990 more narrowly defined the key components of sustainability as: maintaining profitability, supplying food and fiber needs, using non-renewable resources efficiently, enhancing renewable resources, and improving the quality of life in rural areas.

Fisheries Research Report No 104 - Assessment Of The Effects Of A Trial Period Of Unattended Recreational Netting In Selected Estuaries Of Temperate Western Australia, Between 1 January 1994 And 30 June 1995, R. C. Lenanton, R. Allison, Sg Ayvazian

Fisheries Research Reports

Gill nets have been used in coastal marine and estuarine waters of Western Australia to take fish for sale and/or domestic consumption since the State was first settled. However, over recent years, as the usage of these coastal waters has continued to increase, and the competition for fish resources becomes more intense, fishing methods, such as unattended gill nets that are indiscriminate with respect to target species, and generally ,wasteful of resources have become less tolerated by the general community.

As part of a push for tighter controls on the use of recreational gill nets, a requirement for fishers to …

Regional Standards For Rangeland Health And Guidelines For Livestock Grazing Management ... A Progress Report

Range Management

In August 1995, new BLM regulations for rangeland administration went into effect. The new regulations require BLM to establish regional standards for rangeland health and guidelines for grazing management. This publication is a report on the alternatives being considered for the Montana/Dakotas Rangeland Health Standards and Guidelines process.

Bioaccumulation Of Methyl Mercury Through A Food Chain, J. T. Knight

Arkansas Water Resources Center Technical Reports

The bioaccumulation of mercury through the food chain has received much attention in Arkansas during the last three years. The discovery of mercury contamination and subsequent fish consumption advisories in southwest Arkansas have increased public awareness of the potential for bioaccumulation of different toxic compounds. It is postulated that the mercury problem in Arkansas is a result of methylation and resulting bioaccumulation of mercury as methyl mercury. This study was designed to derive a Bioaccumulation Factor (BAF) for mercury in a simple food chain under controlled conditions. A BAF is calculated by dividing the concentration found in the organism by …

A Strategy To Reclaim Wetlands And Balance Biomass Lost To The Cooling Process Of A Nuclear Power Generating Station, Roger R. Locandro

Triennial National Wildlife and Fisheries Extension Specialists Conference: 8th (1996)

Restoration of 20,000 acres of historic wetlands and contiguous upland boundaries is part of a grand-scale estuary enhancement and recovery program, implemented in New Jersey and Delaware by the Public Service Energy and Gas Company (PSE&G). The project is providing a very positive and refreshing signal from the energy industry that wetlands stewardship and cooperation are alive and well.
