Role And Responsibilities Of Agencies For Wildlife Damage Control - An Overview, James E. Miller
Wildlife Damage Management Conference
"A well balanced wildlife management program includes research, the acquisition of land, the development of habitat, the careful regulation of hunting or harvest, the protection of certain species, the enforcement of laws -- and -- the control of animal depredations. Though necessary, this is among the least popular and most controversial of the wildlife management functions. It is, nevertheless, one of the activities which a responsible agency must undertake." This statement is a direct quote from the International Association of Fish and Wildlife Agencies' (IAFWA) Position Paper on Animal Damage Control (1981).
Future Of Wildlife Damage Control And The Cooperative Extension Service, Peter T. Bromley
Future Of Wildlife Damage Control And The Cooperative Extension Service, Peter T. Bromley
Wildlife Damage Management Conference
The driving forces which determine the role of the Cooperative Extension Service in wildlife damage control are (1) the demand for information by the public, (2) the degree of support for programs at the national level, and (3) the level of professionalism exhibited by Cooperative Extension Agents and subject matter Specialists. Analysis of several trends suggests that the Cooperative Extension Service role in Wildlife Damage Control will increase in coming years. The movement of urban people into rural settings will create greater demands for wildlife damage control information. Likewise, the expansion of wildlife population into urban and suburban environments due …
What You Wanted To Know About All You Ever Heard Concerning Snake Repellents, Gary J. San Julian, David K. Woodward
What You Wanted To Know About All You Ever Heard Concerning Snake Repellents, Gary J. San Julian, David K. Woodward
Wildlife Damage Management Conference
Have you ever heard about a way to keep snakes away from your house? Many people in North Carolina have been told by their elders of various ways to repel snakes. When we first started working on this problem in North Carolina, we were amazed at the number of "home remedies" that people believed would protect their property from snakes; and we began to keep a record of these remedies. In 1981, a grant from the Pesticide Impact Assessment Program allowed us to begin to test some of these remedies to determine their value.
Deer Damage And Damage Control In Ohio's Nurseries, Orchards, And Christmas Tree Plantings: The Grower's View, Joel D. Scott, Thomas W. Townsend
Deer Damage And Damage Control In Ohio's Nurseries, Orchards, And Christmas Tree Plantings: The Grower's View, Joel D. Scott, Thomas W. Townsend
Wildlife Damage Management Conference
A survey of white-tailed deer (Odocoileus virginianus) damage was conducted among growers (N = 2,236) of fruit, Christmas tree and nursery crops in Ohio; over 81% responded. Damage was reported by 43.1% of Christmas tree growers, 41.3% of orchardists and 32.5% of nurserymen. Most commonly reported by orchardists as damaged were apples (Malus spp.), by Christmas tree growers were white pines (Pinus strobus), and by nurserymen were maples (Acer spp.). Young plants (x̄ = 7.5 years) were more commonly damaged than older plants of all species. Seasonal damage was most common in …
Public Tolerance Of A Suburban Deer Herd: Implications For Control, Daniel J. Decker, Thomas A. Gavin
Public Tolerance Of A Suburban Deer Herd: Implications For Control, Daniel J. Decker, Thomas A. Gavin
Wildlife Damage Management Conference
Suburban deer populations have been increasing in the eastern U.S., resulting in deer-human conflicts that can not always be resolved by a traditional management approach. Professionals responsible for management of deer damage (herd control and extension education) need information on the extent and nature of deer damage in suburban situations. Attitudes of suburban residential property owners about wildlife in general and deer in particular must be identified so that control measures that are socially acceptable as well as biologically feasible can be formulated. People's tolerance of deer damage and their propensity for undertaking on-site preventive measures need to be analyzed. …
Double-Crested Cormorant Damage To A Commercial Fishery In The Apostle Islands, Wisconsin, Scott R. Craven, Esther Lev
Double-Crested Cormorant Damage To A Commercial Fishery In The Apostle Islands, Wisconsin, Scott R. Craven, Esther Lev
Wildlife Damage Management Conference
The endangered classification of the double-crested cormorant (DCC) in Wisconsin resulted in complete protection and significant management efforts in the 1970's. These efforts, probably coupled with reduced pesticide loads, resulted in a resurgence of Wisconsin cormorant populations from a low of 66 pairs in 1972 to 1028 pairs in 1982. The DCC was reclassified as a threatened species in 1982. This apparent success story did not take into consideration the potential negative impact of an abundant piscivorous bird. In 1978 a colony of DCC's became established on a remote rocky island in the Apostle Islands National, Lakeshore, in Lake Superior. …
Minimum Effective Level Of Methiocarb For Protecting Sprouting Rice In Louisiana From Blackbird Damage, N. R. Holler, P. W. Lefebvre, A. Wilson, R. E. Matteson, G. R. Gutknecht
Minimum Effective Level Of Methiocarb For Protecting Sprouting Rice In Louisiana From Blackbird Damage, N. R. Holler, P. W. Lefebvre, A. Wilson, R. E. Matteson, G. R. Gutknecht
Wildlife Damage Management Conference
Blackbirds cause locally serious losses to rice. The Denver Wildlife Research Center, U. S. Fish and Wildlife Service, and the Rice Research Station, Louisiana State University Agricultural Center have been cooperating in tests to determine the efficacy of methiocarb seed treatments for protecting sprouting rice in Louisiana from blackbird damage. Results from four field tests (1980, 1982, 1983, and 1984) have shown that methiocarb provides good protection when applied to rice seed at the rate of 2.4 g and 1.25 g active ingredient (a.i.)/kg of rice seed (0.25 and 0.125%). Seed treated at 0.6 g a.i ./kg appeared to be …

Marketing Programs And Strategies, J. Kenneth Evans
Kentucky Alfalfa and Stored Forage Conference
Hay has never been widely perceived as a cash crop, therefore, it has historically accounted for a very small part of the total cash sales by farmers. It has been estimated that more than 90% of all hay baled in the state is retained on the producing farms. Most of that which is sold is transported very short distances and of course if one farmer in a community has a good hay year, all do. Organized marketing efforts have been minimal in both scope and successes. In 1978, efforts were initiated toward a more organized system of marketing Kentucky hay. …
The Economics Of Stand Life In The Production Of Alfalfa, W. Donald Shurley
The Economics Of Stand Life In The Production Of Alfalfa, W. Donald Shurley
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is a crop which once established, can provide production of hay for several years thereafter. The productive years of the established crop are often referred to as the stand life. The life of an alfalfa stand is variable depending on many factors including variety grown, soil, weather conditions during the production period, insect and weed pressures, and of course the management skills of the producer in timely harvesting and other production jobs.
Alfalfa In Livestock Feeding Programs, Gary T. Lane
Alfalfa In Livestock Feeding Programs, Gary T. Lane
Kentucky Alfalfa and Stored Forage Conference
A magazine article entitled "Bidders Paid More For Quality at Wisconsin Hay Auction" caught my attention. Did they really pay more money for higher quality. I could not help but think of some hay sales which I have witnessed. One dollar per bale, large bales, small round bales, sixty dollars per ton, and $275 per ton are all some quotes I have heard recently in connection with hay purchases. Not much is said about quality. We may hear relative terms such as good, not much grass, cut early, not rained on or others but not much about nutrient content or …
Grazing Alfalfa, Charles T. Dougherty
Grazing Alfalfa, Charles T. Dougherty
Kentucky Alfalfa and Stored Forage Conference
Alfalfa (Medicaao sativa) is a native of an area south of the Black and Caspian seas and it still grows wild in Iran and eastern Anatolia. Alfalfa was the chosen forage for the fighting horses of ancient armies as long ago as 1800 B.C. when the Kassites conquered Babylon. The spread of alfalfa followed the pathway of armies through the Mediterranean, Europe, and the New World. For ages before man used alfalfa to fuel his fighting animals natural selection processes worked on the evolution of alfalfa and its predecessors. A scenario which would account for the morphology and …
Chemical Preservation Of Alfalfa Hay, Dan O. Riddell
Chemical Preservation Of Alfalfa Hay, Dan O. Riddell
Kentucky Alfalfa and Stored Forage Conference
Kentucky farmers harvest about 3 million tons of hay annually. In order to minimize dry matter losses and quality deterioration, hay should be baled with about 20% moisture. Unfortunately, adequate time required to field-dry hay to 20% moisture is often not available due to weather conditions. This is especially true for the first cutting of alfalfa in the spring. Many farmers are forced to choose between letting cut hay get rained on or baling hay wetter than is recommended. Hay baled with more than 20-25% moisture generally becomes moldy and undergoes a heating process which makes part of the protein …
Biological Control Of Alfalfa Insect Pests, Chris M. Christensen
Biological Control Of Alfalfa Insect Pests, Chris M. Christensen
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is a succulent plant that obviously is good feed for large herbivores such as cattle and horses. Therefore, it should not be surprising that a large number of small herbivores such as insects also find this plant delicious. Fortunately, most of these insects are not major pests. However, we do have a couple pest insects that annually attack this valuable crop and often cause economic damage.
Controlling insect pests is expensive and time consuming. However, not controlling them can be disastrous to the profit margin of the alfalfa producer. Entomologists who work on the insect pests of alfalfa have …
Weed Control In Alfalfa — Present & Future, Charles H. Slack
Weed Control In Alfalfa — Present & Future, Charles H. Slack
Kentucky Alfalfa and Stored Forage Conference
To achieve maximum alfalfa production and maintain excellent stands and forage quality for a number of years, producers need to start including weed control in their management program. Unfortunately good stands are not being established because of early weed competition where herbicides are not used. Alfalfa stands tend to play out before achieving their maximum number of years of production unless maintenance herbicides are used. Fortunately there are now herbicides registered to meet most every phase of alfalfa production.
This paper will deal primarily with the herbicides that are currently labeled for use on alfalfa. Several herbicides that are not …
Fertilizing Alfalfa For Optimum Production, Lloyd W. Murdock
Fertilizing Alfalfa For Optimum Production, Lloyd W. Murdock
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is a high producing crop. Therefore, it only makes sense not to limit its production or longevity by establishing it on unsuitable soil and by the use of unsound fertility practices. It is the aim of this paper to propose practices which will not limit the production of alfalfa, but, also allow it to be done as efficiently as possible with only the necessary inputs.

No-Till Alfalfa — Research And Observations, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
In previous addresses to this Conference, I have suggested four basic goals be included in your alfalfa program: 1) attention to details prior to and during establishment such that you establish a thick, weed-free stand; necessary management to; 2) keep the stand productive for five years; 3) produce five tons per acre per year, and; 4) market your harvest product either as a cash crop or through your livestock program for profit. In the presentations to follow today, information will be presented which, if adapted to your program, will permit you to reach and surpass the above goals.

Kentucky's Soils Potential For Alfalfa Production, Kenneth L. Wells
Kentucky's Soils Potential For Alfalfa Production, Kenneth L. Wells
Kentucky Alfalfa and Stored Forage Conference
A description of Kentucky's land base indicates that of nearly 15 million acres suitable for cropland usage, approximately three-fourths has an erosion hazard potential of some degree, relating largely to steepness of slope (1). For this reason, there is a large potential acreage of alfalfa and other perennial forage crops relating to their sod forming growth habit which provides them an inherent value in erosion control.

An Evaluation Of Trapping Efforts To Capture Bobcats, Coyotes, And Red Fox, John A. Litvaitis, Mark O'Donoghue, Mathew Miller, James A. Sherburne
Wildlife Damage Management Conference
Wildlife biologists are often involved in efforts to capture free-ranging felids and canids. The objective of these efforts is usually to remove individuals causing unwanted or excessive predation, or to obtain study animals. The most common method used to capture carnivores includes some type of leg-hold trap. Numerous references provide information on the technique of leg-hold trapping (Taylor 1971, Musgrove and Blair 1979); however few reports include an evaluation of these methods.
Forage Moisture Testers, George Turner, Doug Overhults
Forage Moisture Testers, George Turner, Doug Overhults
Kentucky Alfalfa and Stored Forage Conference
The quality of forage used for feed is affected by the moisture content at which it was harvested and stored. To guess moisture content from experience or by hand squeezing and wadding is not accurate enough for today's methods of putting up hay, haylage or silage.
There are several very accurate and rapid types of sophisticated moisture indicators used in various industries, but these are too complex and costly to be considered for portable use by farmers. Other smaller instruments are also available that do a less accurate but acceptable job of determining moisture content of forage. One of these …
Alfalfa Production And Marketing — Producer Story, Reeves Davie, Alfred Davie, Gene Davie
Alfalfa Production And Marketing — Producer Story, Reeves Davie, Alfred Davie, Gene Davie
Kentucky Alfalfa and Stored Forage Conference
Our decision to plant a hundred acres of alfalfa in the late summer of 1981 was not made hastily. Past experiences of others in the area who had grown alfalfa commercially, an economic study of the alfalfa hay situation and the declining prices of corn, wheat, and soybeans all had their affect on our decision. However, we did not anticipate the price of corn, wheat and soybeans sinking to the levels they did this past year of 1982.
An Economic Examination Of Kentucky's Potential For Alfalfa Production, W. Donald Shurley
An Economic Examination Of Kentucky's Potential For Alfalfa Production, W. Donald Shurley
Kentucky Alfalfa and Stored Forage Conference
In managing a farm successfully, a major decision faced by the farmer is the choice of enterprises and the level of production for each of the enterprises chosen. For each enterprise or combination of enterprises, an initial investment in land, buildings, and machinery is required. The enterprises chosen and the production levels of each enterprise must be sufficient to reward investments above their cost. Once the choice of enterprises is made and investment incurred, little flexibility exists in making changes among enterprises unless some investments are liquidated and new investments made.
Chemical Preservation Of Alfalfa Hay And Silage, Charles T. Dougherty, J. Kenneth Evans
Chemical Preservation Of Alfalfa Hay And Silage, Charles T. Dougherty, J. Kenneth Evans
Kentucky Alfalfa and Stored Forage Conference
A wide range of substances are being marketed throughout the forage world to enhance, preserve and otherwise modify hay and silage. Some of the products are ineffective, while the benefits of others depend on the correct application and some are used at rates far below that which is effective. Alfalfa can be made into high quality hay and silage without the use of additives if recommended practices are employed, however, when the use of best management practices is not enough, additives may make economic sense. Such is the case in N.W. Europe where the weather prevents haymaking, and the high …
Harvest Management, Harold Vaught
Harvest Management, Harold Vaught
Kentucky Alfalfa and Stored Forage Conference
Harvest management is not an easy topic to address. Every farm or field may present a different situation, thus, decisions must be made by the grower as to the harvest schedule he uses. Most everything I will discuss has research to back it up but I will not reference it. I must say that some of my comments have come from experience and observation over a period of many years.
Managing Leaf Spot Diseases Of Alfalfa, William C. Nesmith
Managing Leaf Spot Diseases Of Alfalfa, William C. Nesmith
Kentucky Alfalfa and Stored Forage Conference
Approximately 25-30 diseases attack and reduce the yield, quality or stand longevity of alfalfa in Kentucky. The largest number of these diseases are leaf spot. Generally, the leaf spots diseases are more important in reducing quality due to leaf loss than direct killing of plants. Some of the leaf spots are severe enough to warrant specific controls aimed directly at them while others are managed through more general practices.
