The Potential Impact Of Endangered Species Legislation On Federal Grazing Lands And The Livestock Industry, G M. Luciuk, B Bristol, T W. Weins, D M. Boyle
The Potential Impact Of Endangered Species Legislation On Federal Grazing Lands And The Livestock Industry, G M. Luciuk, B Bristol, T W. Weins, D M. Boyle
IGC Proceedings (1977-2023)
Crown based grazing is an integral part of the management structure of cattle operations, and is very important to the economic fabric of rural communities. Federal crown lands, such as the PFRA operated community pastures are an integral part of the resource conservation efforts in western Canada. These lands represent a significant reservoir of the remaining natural lands which are important for wildlife habitat. Sustainable management of such contiguous blocks of land is essential for the maintenance of biodiversity. Proposed endangered species legislation would require the development of recovery plans on federal lands for endangered, threatened and extirpated species. Rural …
Concepts For Mining Landscape Development In Eastern Germany With Grazing Animals And Agroforestry, S Eichler, F Herzog
Concepts For Mining Landscape Development In Eastern Germany With Grazing Animals And Agroforestry, S Eichler, F Herzog
IGC Proceedings (1977-2023)
Leipzig South (Saxony) has been heavily transformed by open cast lignite mining. Alternative forms of land use are sought which contribute to an increase of biodiversity and an improvement of soil quality. This could be achieved by the selective introduction of grazing animals and perennials. Specific scenarios for open pits, dumping areas, open pits’ slopes and land reclaimed for agriculture are proposed. Socio-economic drawbacks are outlined.
The Use Of Grasslands To Improve Water Quality In The New York City Watershed, D J. Flaherty, J Drelich Jr
The Use Of Grasslands To Improve Water Quality In The New York City Watershed, D J. Flaherty, J Drelich Jr
IGC Proceedings (1977-2023)
The purpose of this paper is to demonstrate how grasslands are used in the New York City (NYC) Watershed to improve water quality. A Watershed Agricultural Program was established to voluntarily implement Pollution Prevention Best Management Practices on watershed farms. Grasslands have been used in Whole Farm Plans to reduce nutrients, sediments and other toxic materials reaching New York City’s water supply. Rotational grazing has been used to limit access to streams and stream banks and improve nutrient distribution on pastures. Improved grassland management also helps correct the nutrient balance on the farm and facilitates better nutrient management. Brush removal …
Objective Indicators For Monitoring Drought In Grasslands, D H. White, S M. Howden
Objective Indicators For Monitoring Drought In Grasslands, D H. White, S M. Howden
IGC Proceedings (1977-2023)
Australia’s National Drought Policy was ratified by the Commonwealth (Federal), State and Territory governments in 1992. However, a sequence of El Niño-based events that started in Queensland in 1991 culminated in much of Australia experiencing abnormally low rainfall throughout 1994 and into 1995. Many farmers experienced substantial loss of income. The Commonwealth government therefore devised measures to determine which areas had been exposed to exceptional drought so that financial assistance could be directed as effectively as possible. In this paper we discuss progress in developing regionally-sensitive indicators and methodologies to aid in future assessments of drought exceptional circumstances.
Are We Ignoring Science In Our Quest For Simplicity In Range Management?, W A. Laycock
Are We Ignoring Science In Our Quest For Simplicity In Range Management?, W A. Laycock
IGC Proceedings (1977-2023)
Accurate determination of range condition and trend is essential for proper range management. In the United States, the range condition model currently used is not based on up-to-date ecological knowledge. It assumes a single stable state (climax) and linear pathways. Multiple stable state models more accurately depict community dynamics but have not been widely accepted. U.S. Federal land management agencies are using surrogates, such as qualitative “instant trend” measures and substitution of utilization for measured condition and trend to guide management. Most of these short cuts are not based on science. Attacks on livestock grazing by environmentalists are based on …

Socio-Economic And Climate Change In Mongolia - Effects On Grassland Ecosystems, C Opp
IGC Proceedings (1977-2023)
In Mongolia, in combination with strong changes of the whole society during the past 76 years, from the feudal system to socialism and from the socialist system of planned development to the market economy, there are a lot of changes in the use of natural resources all over the country. In consequence of this a lot of effects on grassland ecosystems, caused by socio-economic and climate driving factors, were observed and studied in different scales: zonal, regional, local.

PHYGROW, a hydrologic-based forage simulation model, was parameterized to represent a typical South Texas ranch engaged in the production of cattle and meat goats with an indigenous population of white-tailed deer. Forage production and associated stocking rates for two cattle: goat ratios were simulated for 20 years. Two, ten-year weather scenarios, one representing normal conditions (30% drought years) and one representing dryer weather conditions (50% drought years) were analyzed. Management decision rules were developed for the region to produce estimates of annual animal production and operating cost for the enterprises in each of the four scenarios. These performance and cost …
Linear And Community-Based Processes Of Ethical Decision Making For Grassland Workers, Gary W. Fick
Linear And Community-Based Processes Of Ethical Decision Making For Grassland Workers, Gary W. Fick
IGC Proceedings (1977-2023)
Grasslands are basic elements in sustainable development, but few grassland workers are familiar with concepts of ethical decision making useful in integrating ecological, economic, and sociological components of sustainability. Most published procedures for ethical decision making are based on linear models for individualized social systems with modern technologies. In the context of sustainable agriculture, nonlinear community-based procedures may be more appropriate. In this paper, a nonlinear model from the Haudenosaunee (Iroquois) Indians is compared to more conventional linear procedures. After identification of a problem, linear models often leave the solution of the ethical dilemma (ranking ethical goals when they conflict) …
Policy Options For Decreasing N And P2o5 Losses From Grassland Based Dairy Farms, P.B M. Berentsen, G.W J. Giesen
Policy Options For Decreasing N And P2o5 Losses From Grassland Based Dairy Farms, P.B M. Berentsen, G.W J. Giesen
IGC Proceedings (1977-2023)
Policy instruments for reducing nutrient losses include extension and education, research, financial incentives such as subsidies and levies, and regulations. The potential of these instruments for reducing nitrogen (N), phosphate (P2O5), and ammonia (NH3) losses is examined for Dutch specialized dairy farms on sandy soils. A linear programming model is used to estimate policy impacts. Results indicate that efficiency improvements through extension, education, and research alone have the potential to decrease total N losses to government target levels in 2005 and to erase 92% of the gap between base and target P2O5 losses, but only 24% of the corresponding NH3 …
Production V Conservation: A Policy Dilemma In The Tree Clearing Debate In Queensland, Australia, J C. Scanlan, E J. Turner
Production V Conservation: A Policy Dilemma In The Tree Clearing Debate In Queensland, Australia, J C. Scanlan, E J. Turner
IGC Proceedings (1977-2023)
A process for developing policy for tree clearing that meets the competing goals of conservation and production has been followed. There were two levels at which policy was developed. An overall Statewide policy outlined general targets to meet commitments of the Queensland Government. Local guidelines were developed by a large number of groups containing representatives of government and interested conservation movement and industry representatives. The policy and the local guidelines are an important part of the process used to assess applications for permits to clear woody vegetation.

Forage Production And Performance Of Beef Yearlings Grazing Diploid And Tetraploid Crested Wheatgrass, J D. Bruynooghe, R.D H. Cohen, N W. Holt, P G. Jefferson
IGC Proceedings (1977-2023)
A series of experiments were conducted during 1994 and 1995 at Swift Current, Saskatchewan, Canada to evaluate forage production and animal performance on tetraploid Kirk (Agropyron cristatum (L.) Gaertn.) and diploid Fairway (Agropyron cristatum (L.) Gaertn.) crested wheatgrass pastures under grazing conditions imposed by beef (Bos taurus) yearling steers at four stock density levels (3, 4, 6 and 8 steers ha-1). Total ungrazed forage production for Kirk was greater (<0.05) than Fairway (6302 kg ha-1 vs. 5235 kg ha-1) in 1994 but less (P<0.05) than Fairway in 1995 (3709 kg ha-1 vs. 4633 kg ha-1). Animal performance (average daily gain, animal grazing days and total animal production) did not differ (P>0.05) for steers grazing either Kirk or Fairway pastures. Plant vigour and available energy reserves following one season of grazing were evaluated through etiolated growth with …

Vertical Distribution In Grass Swards: Interactions Between Dry Matter And Nutritional Quality, D R. Buckmaster, R H. Mohtar, S L. Fales
IGC Proceedings (1977-2023)
A field experiment was conducted to study the distribution of mass and quality over plant height throughout the growing season in a pure stand of orchardgrass (Dactylis glomerata L.). When plant density (expressed as kg DM/ha per cm height) is plotted against a height of strata, all treatments show a similar linear shape distribution. ADF and NDF concentrations declined with sward height. Fall treatments had lower ADF and NDF concentrations than summer treatments. Conversely, CP concentrations showed an increase with plant height. Fall treatments showed higher CP than spring and summer treatments. Defoliation management did not affect orchardgrass quality. …

Application Of The Phygrow Forage Production- Runoff Model For Regional Stocking Analysis, J W. Stuth, J R. Conner, W T. Hamilton, D M. Schmitt
IGC Proceedings (1977-2023)
A hydrologic-based forage production model, PHYGROW, was used to simulate forage production and carrying capacity of a subtropical shrubland complex of over 34 species grazed by various ratios of cattle and goats with a population of indigenous white-tailed deer over a 20-yr simulated weather profile. The diet selection algorithm allowed the three animal populations to selectively graze preferred foods based on preferences of plant species, plant parts, and live:dead status by phenological stage. A level of maximum utilization of key species was specified. An incremental analysis of cattle:goat demand ratio was analyzed to determine how different combinations of livestock were …
Using Nested Paddocks To Study Multiple-Paddock Grazing Systems, B E. Anderson, W W. Stroup, W H. Schacht
Using Nested Paddocks To Study Multiple-Paddock Grazing Systems, B E. Anderson, W W. Stroup, W H. Schacht
IGC Proceedings (1977-2023)
There is insufficient information to guide development of multiple paddock grazing systems. Measuring vegetation responses to grazing period/recovery period intervals is prohibitively expensive when using most grazing research designs. Nested paddock designs reduce land area, number of herds, and number of paddocks needed for comparisons. Nested paddocks permit comparisons of animal performance among whole pasture treatments but comparisons are limited for animal performance differences among grazing/recovery period lengths. Nonetheless, nested paddock designs efficiently document vegetation responses to grazing intervals, which may permit predictions of animal performance.
Relationship Between Broadleaf Dock (Rumex Obtusifolius L.) And Seasonal Yield Of Orchardgrass Grazed Pasture, Y Iijima, Y Kurokawa, T Monya, Y Suzuki
Relationship Between Broadleaf Dock (Rumex Obtusifolius L.) And Seasonal Yield Of Orchardgrass Grazed Pasture, Y Iijima, Y Kurokawa, T Monya, Y Suzuki
IGC Proceedings (1977-2023)
In order to grasp the ecology of R. obtusifolius and the effects of it on seasonal yield of grass in grazing pasture, we investigated seasonal sward characteristics and dry matter yield in grazing pasture. Dry matter yield and coverage of R. obtusifolius predominated those of grass after mid-June and mid-August, respectively. Throughout the year the coverage of R. obtusifolius negatively correlated to the grass yield. After August, the grass yield was negatively related to the yield and the population density of R. obtusifolius. From the facts described above, R. obtusifolius seems to reduce grass yield throughout the year, especially …

The Influence Of Light On The Succession Of Calcareous Grassland Using A Gis As An Instrument For Analysis, G Spatz, Th Fricke
IGC Proceedings (1977-2023)
The change of light transmission along a gradient from shrub center to open grassland and its correlation to vegetation composition has been studied in two shrub surroundings on abandoned calcareous grassland. Light measurements were made at soil surface locations in high density and later interpolated to area maps. Low-growing plants were mapped in plots within the shrub area and their shapes subsequently digitized. Using SPANS GIS an overlay of maps representing light transmission, distance to shrub center and apearance of low-growing plants was made by calculating averages in a specified grid to create data sets for a statistical evaluation. The …
The Grazing Manager: A New Application Of The Carrying Capacity Concept, M M. Kothmann, R T. Hinnant
The Grazing Manager: A New Application Of The Carrying Capacity Concept, M M. Kothmann, R T. Hinnant
IGC Proceedings (1977-2023)
Common approaches to evaluating carrying capacity are stocking rate trials for research and trial and error adjustments for ranchers. These approaches are inadequate as operational decision guides for grazing management. The Grazing Manager (TGM) is a generalized management level dynamic model that provides a new approach to stocking rate analysis. Grazing pressure is integrated over time with a function called pasture demand ratio (PDR) which is based on cumulative forage demand relative to cumulative forage production within a forage year. PDR is a dynamic variable that standardizes the forage balance relationship and makes the analysis of stocking rate data more …
Accounting For Selective Grazing In The Stocking Rate Decision, M F. Quirk, J W. Stuth
Accounting For Selective Grazing In The Stocking Rate Decision, M F. Quirk, J W. Stuth
IGC Proceedings (1977-2023)
We describe the development and use of a simple, generic method for predicting botanical composition of herbivore diets, thereby allowing resource managers to consider selective foraging when setting stocking rates. For a particular season and herbivore, we found that forage species fall into one of 3 selection categories: preferred (consistently selected for), undesirable (consistently selected against), and variable (inconsistent selection pattern). Our studies showed that, for most situations, dietary composition is adequately predicted from regression relationships with the field proportions of preferred and undesirable species. We demonstrate how this method can help address issues such as the conservation of preferred …

Seeking A Feminist Approach To Scholarly Innovations In Music Teacher Education, Andrea Maas
Seeking A Feminist Approach To Scholarly Innovations In Music Teacher Education, Andrea Maas
Visions of Research in Music Education
The marketization (Marchand & Orsorno Velázquez, 2016) of higher education impacts faculty through hiring practices, workload structures, and reappointment and promotion policies. Women faculty in fields such as music education need to negotiate masculine discourses and gendered constructions of innovation (Alsos et al., 2013) in a STEM focused economy. Values held by feminist pedagogues could serve as a framework through which to consider a more feminist approach to research and scholarship. Qualities such as equalization of power, collaboration, affective learning, inclusiveness of diversity, and social responsibility may surface through a researcher’s approach to inquiry or in the content itself. This …
Gender And Participation In Popular Music Ensembles: Perspectives Of Modern Band Teachers, Bryan Powell
Gender And Participation In Popular Music Ensembles: Perspectives Of Modern Band Teachers, Bryan Powell
Visions of Research in Music Education
This article explores gender dynamics in popular music education, focusing on the perspectives of modern band teachers across the United States. Drawing from existing literature and a survey of 390 modern band educators, the study examines the extent to which modern band teachers perceive their own gender identities influence student participation and enrollment in elective modern band classes. While the majority of respondents believed their gender does not significantly impact enrollment, female teachers were more likely to indicate that they felt that their gender had an impact on student enrollment compared to their male counterparts. Additionally, the study uncovers challenges …
Musical Engagement: A Conceptual Model Of Contextual Influences, Allison R. Durbin
Musical Engagement: A Conceptual Model Of Contextual Influences, Allison R. Durbin
Visions of Research in Music Education
The purpose of this paper is to propose a conceptual model of contextual influences on musical engagement in a person’s life. I developed this domain-specific conceptual model based on Bronfenbrenner’s (2001) bioecological theory of human development. The model accounts for multiple, interacting contexts that may influence an adolescent’s musical development. In this model, I consider one’s musical life as an acknowledgment of the multitude of ways that music is a part of their daily life. A musical life encompasses more than a formal music education, and as Abeles (2010) posits, “Music education does not exist isolated in the music classroom. …
