Technical Publication Of Wildlife Damage Research, Michael W. Fall, William B. Jackson Feb 1997

Technical Publication Of Wildlife Damage Research, Michael W. Fall, William B. Jackson

Great Plains Wildlife Damage Control Workshop Proceedings

The growth of the subdiscipline of wildlife damage research is producing a wealth of scientific information about methods of resolving conflicts between animals and people. Scientists working on these problems have, for many years, found difficulty in publishing the results of their applied research investigations in traditional scientific journal outlets, leading to a diverse information base that encompasses a variety of technical journals and a large “gray” literature in non-refereed publications. Although a number of current scientific journals welcome papers reporting the results of wildlife damage research, the identification of suitable primary outlets for such work, particularly for studies conducted …

Cultural Control Of Damage To Alfalfa Caused By Pocket Gophers, Ronald M. Case, Debra Baker, James Luchsinger, Bruce Jasch Feb 1997

Cultural Control Of Damage To Alfalfa Caused By Pocket Gophers, Ronald M. Case, Debra Baker, James Luchsinger, Bruce Jasch

Great Plains Wildlife Damage Control Workshop Proceedings

In 1989 we postulated that using different varieties of alfalfa might minimize damages caused by pocket gophers (Geomys spp.). We tested a tap-rooted variety (Wrangler) and a fibrous-rooted variety (Spredor 2). From previous studies, Wrangler out performs Spredor 2 by as much as 27% by the fourth year after planting. Spredor 2, however, has a creeping habit and it sends up new shoots on lateral roots. When a root breaks, it sends up new shoots. Therefore, we predicted that Spredor 2 would be damaged less by below-ground foraging by plains pocket gophers (G. Bursarius). Additionally, Spredor 2 …

Lesser Scaup Depredation And Economic Impact At Baitfish Facilities In Arkansas, M. Chad Philipp, Michael D. Hoy Feb 1997

Lesser Scaup Depredation And Economic Impact At Baitfish Facilities In Arkansas, M. Chad Philipp, Michael D. Hoy

Great Plains Wildlife Damage Control Workshop Proceedings

During the winters of 1994-95 and 1995-96, unusually large numbers of diving ducks were observed on baitfish facilities in Arkansas. Historically, lesser scaup (Aythya affinis) inhabited baitfish ponds with little reported impact on minnow production, and thus little attention was paid to the birds. Unfortunately, minnow crops in the spring of 1995 fell short of expectations and immediate attention became focused on the role lesser scaup may have had on that minnow shortage. Subsequently, lesser scaup were collected from baitfish facilities in an effort to determine their effect on commercial fish farms. Two hundred and twenty-three lesser scaup …

Cost-Effectiveness Of Predator Damage Management Efforts To Protect Sheep In Idaho, Mark D. Collinge, Craig L. Maycock Feb 1997

Cost-Effectiveness Of Predator Damage Management Efforts To Protect Sheep In Idaho, Mark D. Collinge, Craig L. Maycock

Great Plains Wildlife Damage Control Workshop Proceedings

Cost-effectiveness of ADC’s predator damage management efforts was identified as an issue of concern during preparation of an environmental assessment (EA) on predator damage management in southern Idaho. A specific benefit-cost analysis of ADC’s efforts to protect sheep in southern Idaho was prepared to address this issue. This analysis involved a comparison of the difference between 1) the value of livestock losses sustained with a control program in place, plus the costs of implementing the program, and 2) the value of losses that could reasonably be expected without the program in place. This difference, divided by the cost to implement …

Welcome, Charles Lee

Great Plains Wildlife Damage Control Workshop Proceedings

It is a pleasure to welcome you to the 13th Great Plains Wildlife Damage Workshop. It has been 24 years since the 1st Great Plains Workshop was held in Manhattan, Kansas, in December 1973. Attendance has varied throughout the years; focus of the workshop has changed and has evolved to where it is today. As I look around the room, I still see a lot of interest. I still get a lot of calls about wildlife damage control, and I realize there is a great need to share the information that each of us has about wildlife damage control. That …

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen Jan 1997

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen

School of Natural Resources: Faculty Publications

We propose that phosphorus and nitrogen can be removed from polluted water using an ecological water treatment system consisting of periphyton and fish. In the proposed system, polluted water flows through a series of vessels, and the nutrients are taken up by periphyton growing on porous screens. Algal-grazing fish feed on the periphyton and either assimilate or egest the nutrients in mucus-bound feces that settle from the water into a sediment trap. Both the fish and their feces can be harvested as nutrient sinks. In this study we examined the effects of an algal-grazing cichlid (Tilapia mossambica) and …

Review Of Planting The Future: Developing An Agriculture That Sustains Land And Community Edited By Elizabeth A. R. Bird, Gordon L. Bultena, And John C. Gardner, Charles A. Francis Oct 1996

Review Of Planting The Future: Developing An Agriculture That Sustains Land And Community Edited By Elizabeth A. R. Bird, Gordon L. Bultena, And John C. Gardner, Charles A. Francis

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Why should you care about agriculture? Planting the Future provides an eloquent description of the current state of this' most basic human endeavor so critical to survival. Based on a series of surveys and on-farm studies in the North Central and Western states, the book recognizes the bounty of our conventional agricultural industry. More importantly for the future, it details a series of critical problems in the environment, the distribution of economic benefits, and the social dislocation resulting from the consolidation of lands and heavy reliance on fossil fuels. Today's productivity and cheap food in the market have hidden expenses …

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 Jun 1996

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 …

Expectations And Future Opportunities For Fish And Wildlife Extension Programs, Jack H. Berryman Jun 1996

Expectations And Future Opportunities For Fish And Wildlife Extension Programs, Jack H. Berryman

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

The charge to the panel was really in the form of a question: What do customers and cooperators expect and what are the future opportunities for fish and wildlife extension programs?

It's a pretty risky subject. Each state is different; each has different problems and opportunities. And, most of the practitioners—those who know most about it— are here in this audience.

Pete Petoskey and Jim Miller have already presented some historical background and a perspective for the future. And, the fact of these workshops and a glance at the program is clear evidence of the progress being made. The professionalism, …

Who Are Our Clientele?, Robert D. Brown

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

The title of this session asks us to address what our clientele want, but I think we first need to address a more basic issue—who are our clientele, or at least who might they be in the future? We've given this a lot of thought in Texas in the past year or so, as we find that we have one of the most rapidly growing and changing states in the nation. In my position as department head in Texas, it is imperative that I be aware of those changes, and that I provide leadership as to how our extension program …

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 …

Professional Society, State Agency, And Extension Partnerships Needed For Formal Continuing Education Of Wildlife Professionals, Brian K. Miller

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

While professionals readily desire continuing education programs to sharpen and update their skills, distractions, demanding schedules, lack of employer support, and expense often create barriers for regular continuing education attendance. Many professions such as accountants, pharmacists, and lawyers have a formal certification criteria which requires post-graduate testing to obtain certification and then participation in continuing education to maintain certification. The prestige of becoming a CPA, a licensed engineer, or a member of the bar carries an assurance of a certain level of competence and often translates into higher salaries for those who have achieved it. Therefore, there is a motivation …

Finding Your Song, John Munn

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

Planet Earth is a magnificent mix of things that make "living" possible. Delicate mixtures of chemicals, minerals, gases, and waters bathe us. Earth is just the right distance from our sun to provide the energy, driving all the systems—necessary for life—as we know it. Some refer to this as the Great Balance of Life.

How well are these systems balanced, and what would it take for the Planet to lose its ability to create and sustain Life?

We are all aware of the long list of environmental problems facing us. We are also aware of the scientific uncertainties that make …

A Tax Incentive To Encourage Wildlife Management: The Texas Example, Charles W. Ramsey Jun 1996

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 Jun 1996

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 …

Habitat Management Planning: Blending Commercial Forest Management And The Protection Of Forest Ecosystems, Including Their Wildlife Communities, James A. Rochelle

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

The purpose of a Habitat Management Plan is to use the best available science, within an adaptive framework, to provide habitat for a wide variety of native forest wildlife species while profitably managing private land for wood production. This process is currently under development by Weyerhaeuser Company in Washington State. The process starts with a Watershed Analysis conducted under the forest practices laws of the state. In this analysis, technical experts of the appropriate disciplines identify the causal mechanisms behind those processes (mass wasting, surface erosion, temperature regulation, etc.) which are related to fish habitat and water quality. With knowledge …

Sustainable Channel Catfish Farming: Low Management Production Through Modified Stocking And Feeding Practices, William A. Wurts, Forrest Wynne Jun 1996

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.

Development And Management Of Fishing Leases, Billy Higginbotham, Greg Clary Jun 1996

Development And Management Of Fishing Leases, Billy Higginbotham, Greg Clary

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

The popularity of developing sportfish leases is increasing rapidly in the South, much as development of hunting leases has done over the past three decades. This trend is occurring because an increasing number of: (1) landowners realize that their ponds and reservoirs are valuable resources capable of generating additional profits and (2) anglers desire a level of exclusivity not normally available on public waters. A sound economic evaluation of sportfish leasing opportunities is essential if landowners are to identify their most profitable alternatives. Net present value analysis is recommended as one method for evaluating compared profitability of selected investment and …

Wet And Wild: Why Landowners Restore Wetlands, Jim Pease Jun 1996

Wet And Wild: Why Landowners Restore Wetlands, Jim Pease

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

In the past 10 years, many natural resource agencies and conservation organizations have been involved in wetland restoration. In Iowa alone, between the Wetland Reserve Program (WRP), the Emergency WRP (EWRP), and the Private Lands Program of U.S. Fish and Wildlife Service, over 60,000 acres of palustrine and riparian wetlands have been restored, mostly on private land. This has dramatically reversed 150 years of decline in wetland acres. Other states have similar stories. What motivates landowners to participate in such programs? We undertook an 18-state survey to try to answer the question.

A phone survey of 305 participants in these …

Fisheries And Wildlife Habitat Incentive Programs In Missouri: Partnerships In Land Stewardship, Robert A. Pierce Ii Jun 1996

Fisheries And Wildlife Habitat Incentive Programs In Missouri: Partnerships In Land Stewardship, Robert A. Pierce Ii

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

Fish and wildlife resources are highly valued by Missourians. Over 70% of Missouri residents annually participate in fisheries and wildlife activities. However, the future of fisheries and wildlife conservation depends to a large extent on the land-use decisions made by landowners, as approximately 93% of the state is under private ownership. These landowners have different motivations, circumstances, and land ownership objectives which govern their management decisions.

Educational programs which enable landowners to make informed decisions regarding the conservation of fish and wildlife are critical to land stewardship and resource sustainability. Although idealistic concepts, "stewardship" implies "care and responsible management" of …

Extension Wetlands Education In Texas, Darrin Bauer, Will E. Cohen

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

The United States has lost more than half of the wetlands that existed prior to European settlement. Wetlands continue to be lost at an alarming rate due to human disturbance and natural processes. The loss of our countries' wetlands is costing our society greatly. Wetlands perform many functions that are beneficial, such as water filtration, recharging groundwater, providing natural flood control, and supporting a wide variety of birds, fish, mammals, amphibians, insects, and plants. Numerous commercially important fish also require wetlands to survive. Wetlands also provide many recreational opportunities.
