Practical Grazing Management And Feed Strategies To Alleviate Fescue Toxicosis, Glen Aiken
Practical Grazing Management And Feed Strategies To Alleviate Fescue Toxicosis, Glen Aiken
Kentucky Grazing Conference
Tall fescue grown in Kentucky is productive and persistent and that is why the state has 5 million acres of the stuff! Fescue has tolerances to drought, low fertility, and overgrazing that are attributed to a fungal endophyte which infects most tall fescue plants. Unfortunately, these advantages of tall fescue that livestock producers appreciate are offset by reduced calving percentages and calf weight gains caused by consumption of ergot alkaloids produced by the endophyte. Ergot alkaloids affect the physiology of cattle to cause elevation in body temperature, reduced sweating, retention of winter hair coats and uncontrollable growth of summer hair …
Herbicide Options For Pasture Weed Control, Jonathan D. Green
Herbicide Options For Pasture Weed Control, Jonathan D. Green
Kentucky Grazing Conference
Weeds have become more evident and problematic in grazed pastures as forage and livestock production systems have intensified. As animals consume the more desirable and palatable plant species in pastures, weedy plants become more abundant. In particular, animals tend to avoid grazing plants which contain thorns, prickly spines, or are unpalatable making some pastures less productive. In fact, many of the more problematic plants observed in Kentucky’s grazed pastures possess these characteristics including thistles, spiny amaranth (spiny pigweed), horsenettle, common cocklebur, tall ironweed, and buttercups.

Kentucky Grazing Conference
Since 2001-2002 and the outbreak of Mare Reproductive Loss Syndrome (MLRS) the University of Kentucky has been developing stronger ties with the state’s equine industry. Approximately 30% of the foal crop was lost in the Central Bluegrass region during this period with a devastating impact on the industry. Traditionally, many Thoroughbred farms have functioned as independent entities, but MLRS helped them to realize that the University of Kentucky had tremendous amount of expertise that they could provide in the areas of animal health, forage management, and other areas. Initially, there were many theories as to the cause of MLRS with …

Forage Legumes Vs. Fertilizer Nitrogen, Garry D. Lacefield
Kentucky Grazing Conference
A few weeks after I started to work as a Forage Extension Specialist at the University of Kentucky, I heard my mentor and forage idol, Mr. Warren Thompson, speak on forage legumes. Warren, along with Dr’s. Tim Taylor and W.C. Templeton had pioneered the “Pasture Renovation Program” in Kentucky. In addition, Mr. Ed Smith had joined the team and collectively they developed the “Power-til Pasture Renovator.” Warren began his presentation by talking about Kentucky Forages pointing out we were so fortunate to have a good grass base and the opportunity to grow lots of legumes. He also talked about all …
Growth Of Grasses And Legumes: Impact On Grazing, S. Ray Smith
Growth Of Grasses And Legumes: Impact On Grazing, S. Ray Smith
Kentucky Grazing Conference
The primary, cool season, perennial pasture grasses used in Kentucky are orchardgrass, bluegrass, and tall fescue. When not grazed or harvested, each of these passes through successive stages of growth in the spring: 1) leafy vegetative; 2) boot with seed heads enclosed in leaf sheath; 3) heading when the seed heads begin to show and, 4) bloom when pollination has occurred ( Figure 2). Since fiber and lignin contents increase steadily beyond the vegetative stage, while percent protein and digestibility decrease, a major goal in grazing management is to maintain these grasses in the leafy, vegetative stage at all times. …

Kamper Re-Visited Concert (Program), Klaus Kamper, Janet Bass Smith
Mammoth Cave Research Symposia
One hundred years ago, a young German engineer named Max Kämper, came as a visitor to Mammoth Cave. He became so enchanted with the cavern he obtained permission to map the vast system. For the next eight months Max, along with assistance from cave guide Ed Bishop, meticulously put together a highly detailed and accurate map revealing more of the cave than ever before. He probably never realized his work would be admired by generations to follow. Some admire its artistic expression of the cave. Others see beauty in its precision. Ultimately, it has become the iconic map for generations …
Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons
Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons
Mammoth Cave Research Symposia
Serving as guides and explorers at Mammoth Cave partially rescued four men from the obscurity of enslavement. Stephen Bishop, Materson Bransford, Nicholas Bransford and a young man named Alfred all had their very existence documented in the written journals and diaries of various nineteenth century Mammoth Cave visitors. They were physically described, their personalities contemplated, their intelligence gauged, their dialects imitated. At least one abolitionist characterized Stephen Bishop as a charismatic natural leader who could govern the citizenry of freed men in Liberia, should he choose to relocate there.

Mammoth Cave Research Symposia
Twenty-seven year old engineer Max Eduard Kämper arrived in America at 4:00 pm on May 16, 1907 and was greeted by a thunderstorm. His presumed goals were to study American manufacturing methods, learn English, and enrich himself musically. New York had so many German immigrants at the time that German was the second most common language spoken in the city. He stayed at the Belvedere House at the corner of 4th Avenue and 18th Street, and the next day visited acquaintances in Newark. He visited New York landmarks and May 20 visited the famed Hippodrome theater. He moved on May …

Mammoth Cave Research Symposia
In 1908 the German engineer Max Kämper mapped 35 miles of Mammoth Cave, KY. The “Kämper Map,” forgotten in the archives for half a century, is nowadays considered as a masterpiece of underground cartography. Little was known about Max Kämper despite several attempts of American speleo-historians. Most traces were wiped out in two world wars. Nevertheless the authors could find out details of the biography of Max Kämper in German archives. The text is based based upon the radio story “Suche nach Max,” broadcasted by Hessischer Rundfunk - hr1 December 26, 1999, audio download available on http://www.kliebhan.de/kaemper.htm

The Lamps That Lit Their Way, Rick Olson
The Lamps That Lit Their Way, Rick Olson
Mammoth Cave Research Symposia
The distinctive lanterns used at Mammoth Cave from the middle 1800s until 1938 appear to be a locally derived design. Early whale oil railroad lanterns share some characteristics of the Mammoth Cave lanterns, but L&N Railroad lanterns do not appear to have influenced the design. At this time, the design pathway appears to lead from simple open-flame tin candle lanterns to the same lantern with a petticoat lamp affixed in place of the candle, and then finally to the font or oil container being soldered onto the lamp base as one unit. This basic Mammoth Cave lantern varied somewhat over …

Mammoth Cave Research Symposia
Albert Covington Janin was the key architect of tourism development at Mammoth Cave for two decades at the start of the twentieth century, yet little has been written about his tenure. This paper explores his background and accomplishments for the period 1900 to 1910 as an initial attempt to understand his contributions to Mammoth Cave. Material about his activities in relation to Mammoth Cave is synthesized from primary sources in the archival collections of the Huntington Library (HL) of San Marino, California, and the Historical Society of Washington, DC (HSW).

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker
Mammoth Cave Research Symposia
Maps came first at Mammoth Cave, Kentucky. Then came explorers who used the maps to make discoveries as they gained a more comprehensive understanding of the longest cave in the world. The saga of mapping at Mammoth Cave parallels the mapping of North America from the 1600s onward. The first map was an “Eye-Draught Map of Mammoth Cave”, penned from memory in 1811, not a survey, to acquaint merchants with the location of saltpeter dirt. In 1835 the managers of Mammoth Cave hired a surveyor, Edmond Lee, to survey and map and profile the main cave passages. Stephen Bishop, a …

The Evolution Of Cave Mapping And Cartography, Pat Kambesis
Mammoth Cave Research Symposia
“Does it go?” Is the initial question that has inspired many a cave explorer to push the extent of a cave system. But the answer only brings more questions…how far, how long, how deep does it go? During the exploration process, as a cave system reveals its complexity, the questions also change – what is the cave’s relationship to the surface, and to surrounding caves? What are the features and obstacles that the cave contains? Those involved in cave exploration know that the only way to answer these questions is with systematic documentation in the form of cave and surface …

Cottonmill Lake, a 17.4 ha impoundment located in Buffalo County, Nebraska, was a fishery dominated by common carp (Cyprinus carpio). As a result of the poor sportfish populations, angler participation in May and June of 1993 was low (503 ± 210 angler hours) and angler catch rates for all fish species (0.5 ± 0.4 fish/angler hour) was less than desired. In 1995, before rehabilitation, bluegill (Lepomis macrochirus) trap net catch per unit effort (CPUE) was 1.5 ± 0.9, largemouth bass (Micropterus salmoides) catch per hour of electrofishing was 8.0 ± 0.5, and channel catfish (Ictalurus punctatus) …

The Prairie Naturalist
Sunflower fields are well-documented as foraging habitat for fallmigrating blackbirds (Family Icteridae). There is, however, a paucity of information on the use of sunflower fields by non-blackbirds. We assessed non-blackbird use of 12 ripening sunflower fields in the Prairie Pothole Region of central North Dakota. From mid-August to mid-October 2000, we counted 4,129 individual birds, consisting of 22 families and 61 species, in the sample fields and within 5 m of the field edges. We saw the largest number of birds from 18 September to 27 September. The Family Emberizidae (sparrows) accounted for 26% of the species and 20% of …

Using Local Knowledge And Remote Sensing To Map Known And Potential Prairie-Chicken Distribution In Kansas, Michael E. Houts, Randy D. Rodgers, Roger D. Applegate, William H. Busby
The Prairie Naturalist
The greater prairie-chicken (Tympanuchus cupido) and lesser prairie-chicken (Tympanuchus pallidicinctus) have experienced considerable fluctuations in their range and distribution over time. Having current range maps would help wildlife managers and policy makers with decisions regarding prairie-chicken habitat. To create an updated and accurate map of the Kansas prairie-chicken range, a two-pronged approach was implemented. First, a map of potential habitat was created by using known habitat preferences and avoidance factors. Second, a preliminary map showing the distribution of greater and lesser prairie-chickens was created and mailed to regional experts for comments and edits. The returned edits …

Estimating Soil Seed Bank Characteristics In Ponderosa Pine Forests Using Vegetation And Forest-Floor Data, Scott R. Abella, Judith D. Springer
Public Policy and Leadership Faculty Research
Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition before planning management activities facilitates proactive management by providing early alerts of exotic species presence and of abilities of seed banks to promote colonization by desirable species. We developed models in ponderosa pine (Pinus ponderosa) forests in northern Arizona to estimate the size and richness of mineral soil seed banks using readily observable vegetation and forestfloor characteristics. Regression models using three or fewer predictors …
