Grassland And Avian Biodiversity Within Irish Agriculture, Barry J. Mcmahon, J. Whelan Aug 2023

Grassland And Avian Biodiversity Within Irish Agriculture, Barry J. Mcmahon, J. Whelan

IGC Proceedings (1997-2023)

In the last quarter of the 20th century, populations of farmland birds have declined markedly, representing a severe threat to biodiversity (Donald et al., 2001). Because the vast majority of Irish farmland is devoted to intensive grassland, it is important to establish what quality of habitat this provides for biodiversity, especially avian. This study aimed to establish the avian species on the selected sites, compared with the total number of species that have been recorded on Irish farmland in recent years, as documented by the Complete Guide to Irish Birds (Dempsey & O'Clery, 2002).

The Effect Of Burning Abandoned Reclaimed Land In Early Spring On The Distribution Of An Endangered Grassland Bird Species - The Japanese Marsh Warbler, T. Sugiura, E. Ochiai, M. Baba, H. Kobayashi Aug 2023

The Effect Of Burning Abandoned Reclaimed Land In Early Spring On The Distribution Of An Endangered Grassland Bird Species - The Japanese Marsh Warbler, T. Sugiura, E. Ochiai, M. Baba, H. Kobayashi

IGC Proceedings (1997-2023)

The Japanese Red Data Book of Birds lists the Japanese Marsh Warbler (Locustella pryeri pryeri) as an endangered species. It feeds and breeds in-reed dominated (Phragmites australis (Cav.) Trin.ex.Steud.) grassland in N Japan. Expanses of reclaimed land (Hotokenuma) are its largest breeding grounds. Each April, fire management is used to rid the area of the dead reed material amassed from the previous year. Circa 1 month after burning, the species returns to the area to inhabit and breed in the unburned areas. Fire use to manage grasslands is an important tool for the conservation and management of …

Lapwing And Redshank Nesting Sites On Coastal Marshes: Does Sward Structure Matter?, D. Durant, Muriel Tichit, E. Kernéïs Aug 2023

Lapwing And Redshank Nesting Sites On Coastal Marshes: Does Sward Structure Matter?, D. Durant, Muriel Tichit, E. Kernéïs

IGC Proceedings (1997-2023)

Grazing is central to the debate on wildlife conservation. Agricultural grasslands are the main breeding areas for many waders and grazing is very important in grassland use by these species. Waders, groundnesting birds, are very sensitive to sward structure for nesting (Milsom et al., 2000). As a marsh has different grazing regimes, all fields are not equally suitable for waders. This study evaluated the factors affecting lapwing and redshank selection of nesting sites. Also, the hypothesis was tested that sward structure (mean grass height, frequency of tussocks) is an important factor affecting this selection.

Management Of Grasslands Used By Waders: Integrating Time And Key Spatial Scales Of Grazing Processes, M. Tichit, D. Durant, O. Renault, E. Kernéïs Aug 2023

Management Of Grasslands Used By Waders: Integrating Time And Key Spatial Scales Of Grazing Processes, M. Tichit, D. Durant, O. Renault, E. Kernéïs

IGC Proceedings (1997-2023)

Agriculture has many functions. Mainly through agri-environment schemes, farmers are asked to manage grasslands of special value to conserve biodiversity. Assessment of grazing as an ecological factor of variation of grassland characteristics is needed to understand how grazing contributes to grassland management for species conservation. Several wader species use wet grasslands preferentially for nesting and foraging. Like many ground-nesting birds, they are very sensitive to the sward structure (see Durant et al., this congress).

A Comparison Of Restored Native Grasslands And Exotic Grass Pastures As Wintering Habitat For Declining Grassland Bird Species In The Southeastern United States, A. B. Mcmellen, S. H. Schweitzer Aug 2023

A Comparison Of Restored Native Grasslands And Exotic Grass Pastures As Wintering Habitat For Declining Grassland Bird Species In The Southeastern United States, A. B. Mcmellen, S. H. Schweitzer

IGC Proceedings (1997-2023)

Southeastern grasslands were not pristine when the first Europeans arrived in the 15th century. American Indians had modified the landscape through centuries of fire use, cultivation, and other activities (Denevan, 1992). However, native southeastern grasslands did not evolve with disturbance from intensive grazing. Livestock and intense grazing pressure arrived with the Europeans. Modifications to southeastern grasslands by the early 1900s included exclusion of fire, intensive grazing, and introduction of cultivated, sodforming grasses, which resulted in an increase in hardwood trees and shrubs, changes in herbaceous species composition, and the near extirpation of native warm-season species such as switch grass ( …

Agricultural Intensification: Have Sown Pastures Damaged The Environment?, John G. Mcivor, C. K. Mcdonald, Neil D. Macleod, Ken C. Hodgkinson Aug 2023

Agricultural Intensification: Have Sown Pastures Damaged The Environment?, John G. Mcivor, C. K. Mcdonald, Neil D. Macleod, Ken C. Hodgkinson

IGC Proceedings (1997-2023)

Concerns are growing about the impact of agriculture on the environment. Particular concerns have been expressed about the impacts of intensive agriculture (e.g. cropping involving fertiliser, pesticides, limited germplasm, fuels, etc) on biodiversity, and both on-site (e.g. soil health and fertility) and off-site resources (e.g. pesticide contamination). Less intensive agriculture (e.g. sown pastures) can also have undesirable impacts. In the woodlands of eastern Australia sown pasture development has been associated with loss of native vegetation and wildlife habitat, accelerated soil acidification, salinisation and poor tree health (McIntyre et al., 2002). Based on this, there have been calls to restrict …

The Use Of Ecological Indicators In Studies Of Ecological Recovery For Sustainable Management Of Grazed Grassland Ecosystems, G. A. Heshmati Aug 2023

The Use Of Ecological Indicators In Studies Of Ecological Recovery For Sustainable Management Of Grazed Grassland Ecosystems, G. A. Heshmati

IGC Proceedings (1997-2023)

Early warning systems that depend on the selection of suitable indicators of thresholds are useful (Friedel, 1991). An ideal indicator should be unbiased, sensitive to changes, predictive, referenced to threshold values, data transformable, integrative and easy to collect and communicate (Liverman et al., 1988). Methods for selection of indicators for assessing ecosystem health are being developed (Pyke et al., 2002). This paper examines the situation in grassland vegetation grazed by sheep in a semi arid region of northeastern Iran.

Investigation On The Temporal Variation Of Vegetation Cover In Karaj River Basin (1973-1993), M. Mohseni Saravi, A. Malekian, B. Mohammadi Golrang Aug 2023

Investigation On The Temporal Variation Of Vegetation Cover In Karaj River Basin (1973-1993), M. Mohseni Saravi, A. Malekian, B. Mohammadi Golrang

IGC Proceedings (1997-2023)

Area changes in vegetation cover depend on several climatic and edaphic factors as well as direct and indirect human activities. Vegetation maps in a region are mosaics of various associations and types, which clearly show their characteristics and provide a useful tool for classification purposes. Kochler (1967) suggested that vegetative forms and species are 2 most important factors for descriptive purposes. This research aimed mainly to determine the vegetation types based on floristic-physiognomic forms and comparison of vegetation cover maps of 2 different dates to clarify the temporal variations of vegetation cover over this period. This detection of change would …

Operating Systems Of The Meadows In Semi-Arid Region Of Algeria, K. Abbas, M. Abdelguerfi-Laouar, Aissa Abdelguerfi, T. Madani, A. Mebarkia Aug 2023

Operating Systems Of The Meadows In Semi-Arid Region Of Algeria, K. Abbas, M. Abdelguerfi-Laouar, Aissa Abdelguerfi, T. Madani, A. Mebarkia

IGC Proceedings (1997-2023)

Permanent meadows are the base of the fodder resources and also provide environmental services (MAP France, 2002). The function of fodder production is no longer solely to ensure bulk agricultural production. It must also allow the development of livestock products of good quality, contribute to environmental protection, the quality of the landscape and ensure a viable economic activity in the rural areas. These areas have decreased greatly (from 1 million ha at the beginning of the century (Lapeyronie, 1982) to less than 300,000 ha in 2000), in particular in the semi-arid zones at high altitude; however they contribute very effectively …

Protection Of Agrobiodiversity: Model Calculations In Rhineland-Palatia: Costs And Implications For Farmer, H. Bergmann Aug 2023

Protection Of Agrobiodiversity: Model Calculations In Rhineland-Palatia: Costs And Implications For Farmer, H. Bergmann

IGC Proceedings (1997-2023)

Biological conservation and production use the same areas of land in less favoured areas. Grassland in these areas makes an important contribution to the protection of agro-biodiversity. However, under existing market conditions and production needs, the use of low yielding grasslands is not economically efficient. The objective of this study was to analyze the economic consequences of different mowing strategies in a small region in Rhineland-Palatia (Germany) that served the protection of two butterfly species.

Contributions Of The United States Department Of Agriculture Natural Resources Conservation Service To Conserving Grasslands On Private Lands In The United States, L. P. Heard Aug 2023

Contributions Of The United States Department Of Agriculture Natural Resources Conservation Service To Conserving Grasslands On Private Lands In The United States, L. P. Heard

IGC Proceedings (1997-2023)

The future of biodiversity in the USA is tied inseparably to activities taking place on private lands. Agriculture is by far the most important user of these lands, with about 50% or 900M acres managed as private cropland, grassland or rangeland. Decisions made by America's farmers and ranchers directly affect grasslands and their impact on food supply, biodiversity, soil protection and water quality. Agricultural programs and policies in the USA have had a large influence on the choices available to farmers and ranchers in land management. Since the 1930s, USDA's Natural Resource Conservation Service (NRCS) has been working with farmers, …

Biodiversity In Grassland: Bangladesh Perspective, B. Hossain Aug 2023

Biodiversity In Grassland: Bangladesh Perspective, B. Hossain

IGC Proceedings (1997-2023)

The rapidly increasing human population in Bangladesh has caused widespread damage to and disturbance of natural habitats and a loss of indigenous wildlife. There are now very few, if any, extensive patches of grassland in Bangladesh and any that might remain are inundated for two-thirds of the year with no alternative refugia available. Most remaining grassland areas are fragmented, heavily used and harvested up to three times a year. Furthermore, the reed lands of northeast Bangladesh were leased out for paper production and are reported to have been entirely destroyed and settled by encroachers. Tall grasslands around rivers and lakes …

Undp-Gef Grasslands Project: Conserving Mountain Biodiversity In Southern Lesotho, W. A. Rodgers Aug 2023

Undp-Gef Grasslands Project: Conserving Mountain Biodiversity In Southern Lesotho, W. A. Rodgers

IGC Proceedings (1997-2023)

The Kingdom of Lesotho contains some 70% of the Drakensberg-Maloti Mountains, recognised as the Eastern Mountains "Centre of Biodiversity and Endemism" of southern Africa. The Mountains have globally significant plant diversity, with unique habitats and high endemism. These resources have been increasingly degraded by a grazing regime based on communal access, with reduced regulatory capability. Lack of ownership has restricted investment in conservation. Lesotho has the lowest Protected Area coverage of any nation in Africa (<0.4%). Biodiversity is thus at risk.

Undp-Gef Grasslands Project: The Southern Africa Botanical Network "Sabonet", Y. Steenkamp, W. A. Rodgers

IGC Proceedings (1997-2023)

This six-year biodiversity capacity building project closes at the end of June 2005. The principal outcomes have been greatly strengthened capacities within, and interaction between, the national herbaria of southern Africa, in order to improve plant taxonomic outputs to better serve the needs of conservation end-users. Grassland plants have in many ways been the main regional focus. The project was based in the National Botanical Institute (NBI) of Southern Africa (now the South Africa Biodiversity Institute - SANBI) and had components in Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, Swaziland, Zambia and Zimbabwe. The NBI provide regional coordination and technical support.

Undp-Gef Grasslands Project: Mainstreaming Biodiversity Into Productive Landscapes: The Southern African Grasslands Programme, C. Maze, W. A. Rodgers Aug 2023

Undp-Gef Grasslands Project: Mainstreaming Biodiversity Into Productive Landscapes: The Southern African Grasslands Programme, C. Maze, W. A. Rodgers

IGC Proceedings (1997-2023)

This is an exciting new initiative under the second strategic priority for the Global Environment Programme (GEF)'s Biodiversity Focal Area: Mainstreaming biodiversity into productive landscapes and sector. The rationale is that whilst grassland biomes cover some 30% of South Africa, (within montane, coastal and high-veld systems) less than 3% is formally protected at national, provincial or private land-owner levels. Over 40% of the grasslands have been totally converted to other land usages and 30% is degraded. Forces of degradation and conversion (cultivation, forests, urban spread) continue. The issues of conservation are of land use and putting in place incentives to …

Undp-Gef Grasslands Project: The Tanzania Montane Grasslands Project, T. Davenport, W. A. Rodgers Aug 2023

Undp-Gef Grasslands Project: The Tanzania Montane Grasslands Project, T. Davenport, W. A. Rodgers

IGC Proceedings (1997-2023)

The Tanzania Southern Highlands and adjacent Nyika montane grasslands in Malawi form a distinct centre of plant diversity and endemism. The area is characterised by complex geology with old basement mountains and much more recent volcanoes (Mount Rungwe) adjacent to the rift valet faulting with Lakes Malawi (Nyasa) and Rukwa. Lake proximity generates rainfall up to 3,000 mm per annum. The maximum altitude is 3,000 m asl.

Long Term Results For The Naturalisation Of River Valley Grassland In The Lower Floodplains Of The River Oder, G. Schalitz, A. Behrendt Aug 2023

Long Term Results For The Naturalisation Of River Valley Grassland In The Lower Floodplains Of The River Oder, G. Schalitz, A. Behrendt

IGC Proceedings (1997-2023)

The flooded grassland area in the lower reaches of the River Oder covers about 10,000 ha, of which 4,000 ha are situated on the German side and the remainder in Poland. In spite of extreme flooding conditions (annual winter flooding from 15 Dec. to 15 April and occasional summer flooding) the area was used very intensively in GDR times. After the political change in 1989, the management of the cross-border GermanPolish National Park, which was situated in this area, was changed abruptly to extensive grassland utilisation. This paper reports on changes in the composition and productivity of the grassland.

The Effects Of Water Availability On Plant Growth In Sesleria Albicans - Dominated Grasslands In The Burren, Co. Clare, Patrick Moran, S. Ryal, B. Osborne Aug 2023

The Effects Of Water Availability On Plant Growth In Sesleria Albicans - Dominated Grasslands In The Burren, Co. Clare, Patrick Moran, S. Ryal, B. Osborne

IGC Proceedings (1997-2023)

The Burren is a karstic region in the west of Ireland characterised by large areas of exposed limestone pavement with sparse vegetation. Despite the prevailing oceanic climate and high rainfall, substrate volumetric water content values are similar to those of semi-arid habitats due to high run-off. As a consequence, plants growing on the pavement regularly experience water deficit during the summer months. S. albicans, a species reported to be tolerant of water deficits, is one of the most abundant species growing on the limestone pavement. The objective of this study was to determine the impact of water availability on …

Forage Yield And Soil Moisture Content In Panicum Maximum Cv. Tanzania Monoculture And In A Mixture With Leucaena Leucocephala With Different Densities In Mexico, H. J. Delgado Gómez, Juan C. Ku-Vera, J. Ku Vera, J. Escamilla Bencomo, P. A. Velázquez Madrazo

IGC Proceedings (1997-2023)

Cattle production is limited by forage availability during the dry season since water and soil fertility are the main factors limiting production. Leucaena leucocephala has good nutritive value (24-30% CP). It can stand drought and grazing and so its introduction into pastures is recommended as an alternative to forage production during the dry season. The aim of this study was to assess the effect of the introduction of L. leucocephala with different densities on biomass production of P. maximum and soil water content.

Effects Of Supplemental Irrigation On Berseem Seed Crop In A Semi-Arid Mediterranean Environment, G. Amato, D. Giambalvo, C. Scarpello, P. Trapani Aug 2023

Effects Of Supplemental Irrigation On Berseem Seed Crop In A Semi-Arid Mediterranean Environment, G. Amato, D. Giambalvo, C. Scarpello, P. Trapani

IGC Proceedings (1997-2023)

Berseem seed production in Mediterranean environments is strongly influenced by soil water availability, particularly during spring growth. A long-term study (11 years) in Sicily recorded seed yields of between 0 and 1600 kg/ha, for an annual rainfall range of 289 to 867 mm (Stringi et al., 2001). It was proposed that water irrigation during sensitive growth stages could increase and stabilize seed yield. This research investigated the response of berseem seed crop to low levels of irrigation applied at different growth stages.

Evaluation Of Sweet Grain Sorghum Silage For Dairy Cows As An Alternative To Irrigated Maize Silage, W. G. Do Nascimento, Y. Barrière, X. Charrier, Christian Huyghe, J. C. Emile Aug 2023

Evaluation Of Sweet Grain Sorghum Silage For Dairy Cows As An Alternative To Irrigated Maize Silage, W. G. Do Nascimento, Y. Barrière, X. Charrier, Christian Huyghe, J. C. Emile

IGC Proceedings (1997-2023)

Under European dairy cattle rearing conditions, whole plant maize silage is the main part of the dairy cow's diet especially during the winter season. Nevertheless maize production can be limited in some areas because summer rainfall is insufficient and so irrigation is necessary. Grain sorghum hybrids, and especially sweet sorghum types, are potentially of great interest to avoid this water consumption (Lemaire et al., 1996, Legarto, 2000). For this reason we evaluated in 2003 the benefits and limits of a sweet grain sorghum silage for dairy milk production, compared to an irrigated maize silage. We paid particularl attention to …

Enhancing Water Use Efficiency On Irrigated Dairy Pastures With Nitrogen Fertiliser, Frank R. Mckenzie, J. L. Jacobs, G. N. Ward Aug 2023

Enhancing Water Use Efficiency On Irrigated Dairy Pastures With Nitrogen Fertiliser, Frank R. Mckenzie, J. L. Jacobs, G. N. Ward

IGC Proceedings (1997-2023)

Low summer rainfall in southwest Victoria, Australia, restricts pasture growth and limits milk production. One fifth of dairy farmers in the region have some capacity to irrigate during summer. Irrigated dairy pastures are relatively poor utilisers of water with water use efficiencies (WUE) of about 1 t DM/ML water (Ward et al. 1998). Using nitrogen (N) fertiliser may increase dry matter (DM) yields for a given amount of water. Data on N response efficiencies from irrigated pasture in southwest Victoria are lacking. Two experiments determined the potential of N fertiliser to maximise the conversion of irrigated water to pasture …

Responses Of Irrigated Pasture Nutritive Characteristics To Summer Nitrogen Fertiliser, Frank R. Mckenzie, J. L. Jacobs, G. N. Ward Aug 2023

Responses Of Irrigated Pasture Nutritive Characteristics To Summer Nitrogen Fertiliser, Frank R. Mckenzie, J. L. Jacobs, G. N. Ward

IGC Proceedings (1997-2023)

Low summer rainfall in southwest Victoria, Australia, restricts pasture growth and reduces pasture nutritive value thereby limiting potential milk production. One fifth of dairy farmers in the region have some capacity to irrigate during summer and nitrogen (N) fertiliser is used to enhance pasture dry matter (DM) yield. Data on the effects of N fertiliser on irrigated pasture nutritive characteristics during summer in southwest Victoria are lacking. Two experiments determined the potential of N fertiliser to improve pasture nutritive (crude protein, CP and metabolisable energy, ME) value during summer.

Balancing Water Use Efficiency And Milk Production In The Sub-Tropics, Mark N. Callow, S. K. Kenman Aug 2023

Balancing Water Use Efficiency And Milk Production In The Sub-Tropics, Mark N. Callow, S. K. Kenman

IGC Proceedings (1997-2023)

Queensland dairy farmers have had to confront in the last 5 years deregulation of the milk pricing system, resulting in a 25% reduction in farm gate price for milk in the year 2000, and drought. Many storage dams are significantly below capacity and regulatory authorities have imposed restrictions on irrigation water allocations. Major changes in farm business strategies were needed to overcome the shortfall in milk income. Production systems had to change to deliver more milk more efficiently and become more profitable. A farmlet study was developed in the sub-tropical dairy region of Queensland to evaluate 5 very different farm …

Effect Of Timing And Intensity Of Drought On Perennial Ryegrass Seed Yield, R. J. Martin, R. N. Gillespie, S. Maley Aug 2023

Effect Of Timing And Intensity Of Drought On Perennial Ryegrass Seed Yield, R. J. Martin, R. N. Gillespie, S. Maley

IGC Proceedings (1997-2023)

Perennial ryegrass seed worth about $50 million is produced annually in Canterbury, New Zealand (Rowarth 1998). Ryegrass seed production in New Zealand is often affected by drought, reducing both seed number and seed size (Rolston et al., 1994). Irrigation management recommendations are not currently available for farmers growing ryegrass seed crops. To quantify the effect of water stress on perennial ryegrass seed yield, we carried out an experiment in a rainshelter where rainfall was excluded from experimental plots otherwise exposed to normal weather (Martin et al., 1990).

Study On Transpiration Rates Of Vicia Villocea And Bromus Inermis Species, S. H. R. Sadeghi, N. Rahimzadeh

IGC Proceedings (1997-2023)

Ecohydrology is concerned with the interaction between the hydrological and plant processes. Some aspects of the hydrologic cycle, such as transpiration and interception have received little attention owing to difficulties in field measurements. Quantifying the components of water balance for a watershed is crucial for understanding the dominant hydrologic processes occurring in a basin (Flerchinger & Cooley, 2000). Water use by vegetation is controlled by the water uptake by roots, the transfer of liquid water through plants and vapour loss from the leaf surfaces by the opening and closure of the stomata (Roberts, 2000) i.e. transpiration. Comparison of transpiration of …
