Abstract:
Renovating pastures to increase forage species diversity is a burgeoning practice among producers. Over a century of grassland and small-plot research suggests that increasing plant diversity can lead to improved pasture productivity, resilience, and soil health. However, it remains hard to decipher how these benefits translate to grazed production systems given the limited experimentation in realistic grazing systems. There is a disconnect between ecological and agronomic research regarding what qualifies as a “diverse” grassland or pasture. This review aims to examine the current state of research regarding plant diversity and its potential benefits for soil health in pasture systems, and outlines how we can improve our understanding and implementation of this practice in production systems.

Abstract:
Arrested succession is conspicuous in the abandoned pastures of the Andean piedmont that have encroached upon the tropical montane forests toward higher limits and steeper slopes. Habitat 'shredding' is analysed to depict the current spatial configuration of tropical Andean landscapes, based on fragmentation patterns prompted by seed dispersal ecology and pasture encroachment.Seed dispersal was studied to address the hypo-thesis that seed input constrains the recruitment of montane forest seedlings, thus impeding pasture conversion to forest. It turns out that a better competitor, the tussock grass Setaria sphacelata, is limiting dispersal success due to its bioarchitecture and planting patterns. Because of the variegation of fragments, the area is in danger of landscape homogeneity within a matrix of degraded pasture. Currently, protection of fragmented remnants and restoration of original landscape structure and function are urgent needs for land-use planning toward sustainable development in the region.Restoration ecology is plausible as a means of conservation for degraded Tropandean forests, since human impacts have shredded landscapes entirely. Dispersal ecology may be used to facilitate pasture conversion to forest in equatorial landscapes, but the proactive approach of pasture removal or planting strategy should differ from that for lowland Amazonia, where abandoned pastures are different from those of montane environs. However, the region may be proactively managed only if political decisions include conservation as a goal of development.

Full text
Abstract:
Pasture and animal production from fertilised pastures with varying proportions of sown grass (0-60%) were recorded and compared. The presence of sown grass increased pasture production when compared to natural pasture, but no difference was detected in liveweight or wool production between the var- ious pastures. It is doubtful whether sowing of introduced grasses for wool production can be justified at the levels of grazing intensity usually adopted on the Northern Tablelands.

Abstract:
Sustainable management of native pastures requires an understanding of what the bounds of pasture composition, cover and soil surface condition are for healthy pastoral landscapes to persist. A survey of 107 Aristida/Bothriochloa pasture sites in inland central Queensland was conducted. The sites were chosen for their current diversity of tree cover, apparent pasture condition and soil type to assist in setting more objective bounds on condition ‘states’ in such pastures. Assessors’ estimates of pasture condition were strongly correlated with herbage mass (r = 0.57) and projected ground cover (r = 0. 58), and moderately correlated with pasture crown cover (r = 0.35) and tree basal area (r = 0.32). Pasture condition was not correlated with pasture plant density or the frequency of simple guilds of pasture species. The soil type of Aristida/Bothriochloa pasture communities was generally hard-setting, low in cryptogam cover but moderately covered with litter and projected ground cover (30–50%). There was no correlation between projected ground cover of pasture and estimated ground-level cover of plant crowns. Tree basal area was correlated with broad categories of soil type, probably because greater tree clearing has occurred on the more fertile, heavy-textured clay soils. Of the main perennial grasses, some showed strong soil preferences, for example Tripogon loliiformis for hard-setting soils and Dichanthium sericeum for clays. Common species, such as Chrysopogon fallax and Heteropogon contortus, had no strong soil preference. Wiregrasses (Aristida spp.) tended to be uncommon at both ends of the estimated pasture condition scale whereas H. contortus was far more common in pastures in good condition. Sedges (Cyperaceae) were common on all soil types and for all pasture condition ratings. Plants identified as increaser species were Tragus australianus, daisies (Asteraceae) and potentially toxic herbaceous legumes such as Indigofera spp. and Crotalaria spp. Pasture condition could not be reliably predicted based on the abundance of a single species or taxon but there may be scope for using integrated data for four to five ecologically contrasting plants such as Themeda triandra with daisies, T. loliiformis and flannel weeds (Malvaceae).

Abstract:
Total and germinable soil seedbanks (litter and soil) were studied for a native pasture and three sown pastures (dominated by Phalaris aquatica L. cv. Sirosa) in northern New South Wales from 1993 to 1996. Soil core samples were taken from continuously grazed plots for both pasture types and two oversown treatments in the native pasture and from a spring-autumn rest treatment at the sown pasture sites. At each site above ground herbage mass was also estimated regularly as part of the Temperate Pasture Sustainability Key Program. For all sites and treatments, the proportion of germinable seeds as a percentage of the total (dormant and germinable) seedbank ranged from 1–26% for the native pasture and 1–39% for the sown pastures. Germinable seed numbers ranged from 280 to 26,110 seeds per m2, while total seedbank numbers were from 6700 to 178,360 seeds per m2. Native pasture herbage mass was dominated by native perennial grasses, but seeds of these species were less than 20% of the total seed bank in all treatments in 1994 and 1995. At the sown pasture sites, most of the germinable (51–92%) and total (65–97%) seedbanks were either barnyard grass (Echinochloa crus-galli (L.) Beauv, annual ryegrass (Lolium rigidum Gaudin), subterranean clover (Trifolium subterraneum L.) or wireweed (Polygonum aviculare L.). Since seeds of annuals and other forbs generally dominated both the total and germinable seedbanks of these perennial grass-based pastures, these species were likely to increase over time. Seeds of the sown perennial grass Phalaris aquatica L, cv. Sirosa were less than 1% of the total seedbanks in pastures sown in 1990 and less than 3% of those sown in 1979. With above average summer rainfall at the native pasture site in 1996 and prolific growth of redgrass, seeds of this species were 38–63% of the total and 11–29% of the germinable seedbank in May 1996. Except at this site and time, the species composition of the total and germinable seedbanks did not generally reflect the dominance of the above ground herbage mass of these pastures by perennial grasses.

Abstract:
Pastures are the basis of most forms of agricultural production on the New South Wales central and southern tablelands. Pastures occupy the bulk of the region's landmass and pasture-based livestock production annually contributes more than three-quarters of the regional gross value of rural production. Throughout the region, there is substantial variation in pasture composition, ranging from high quality introduced perennial grasses and legumes to pastures comprising mainly low quality native species. This paper examines the economics of the main categories of temperate pastures over a range of soil fertility-rainfall environments on the south-eastern tablelands areas of New South Wales. Using a linear programming model and discounted development budgets, the results demonstrate the strong influence of the environment on the economics of the individual pasture systems. The highest economic returns in both the short and longer-terms were to the introduced perennial grass pastures in most of the environments. Pastures based on introduced legumes and the high quality native species also generated sound economic returns, although there are recognised problems with the persistence of the legume pastures. Over time, the returns to the better quality native pastures compare favourably with the introduced legumes and are better suited to acidic soils than the perennial grasses. Low quality native species produced relatively poor economic returns in all environments and unfortunately, are the main pasture type in the region's less favourable environments.

Abstract:
The biomass and composition of grazed pastures near Menindee, in westem New South wales, were estimated over a range of seasonal condilions between 1980 and 1985. Differences in biomass and composition of pastures grazed separately by kangaroos and by a mixture of sheep and kangaroos were minor. Pasture biomass ranged from 7 kgha during a drought to 1,100 kgha following high summer rainfall. Overall, biomass average 374 kgha with a slandard deviation among years of 302 kgha. Pasture biomass fluctuated markedly among calendar seasons and years in response to erratic rainfall and grazing. I-Iigh summer rainfall triggered a switch in pasture dominatnace from annuals to shoa-lived perennials.

Full text
Abstract:
Pasture persistence is highly rated by sheep and beef farmers as an important factor determining wholefarm performance. Managing pastures to ensure the persistence of newly sown pasture species must be considered as a part of the decision making process of the whole farm. The farmer aims to optimise the outcomes of resource use over time, rather than maximise any single resource, and therefore grazing decisions must be considered in this context. Pasture renewal is a major event-driven disruption that replaces current pasture species with competitive species, creating a grass-legume complex that has a tendency to develop towards a community of plants that tolerate the local environmental stress. Pasture persistence can be improved through managing the impacts of and interactions between environmental stressors on the pasture. Interactions between pasture management options, such as grazing and fertiliser, and the major environmental stressors of soil moisture, temperature, soil fertility, grazing and pests are discussed. Keywords: ecology, environmental stressors, farm systems, grazing management, pasture persistence.

Full text
Abstract:
A survey was conducted in central inland Queensland, Australia of 108 sites that were deemed to contain Aristida/Bothriochloa native pastures to quantitatively describe the pastures and attempt to delineate possible sub-types. The pastures were described in terms of their floristic composition, plant density and crown cover. There were generally ~20 (range 5–33) main pasture species at a site. A single dominant perennial grass was rare with three to six prominent species the norm. Chrysopogon fallax (golden-beard grass) was the perennial grass most consistently found in all pastures whereas Aristida calycina (dark wiregrass), Enneapogon spp. (bottlewasher grasses), Brunoniella australis (blue trumpet) and Panicum effusum (hairy panic) were all regularly present. The pastures did not readily separate into broad floristic sub-groups, but three groups that landholders could recognise from a combination of the dominant tree and soil type were identified. The three groups were Eucalyptus crebra (narrow-leaved ironbark), E. melanophloia (silver-leaved ironbark) and E. populnea (poplar box). The pastures of the three main sub-groups were then characterised by the prominent presence, singly or in combination, of Bothriochloa ewartiana (desert bluegrass), Eremochloa bimaculata (poverty grass), Bothriochloa decipiens (pitted bluegrass) or Heteropogon contortus (black speargrass). The poplar box group had the greatest diversity of prominent grasses whereas the narrow-leaved ironbark group had the least. Non-native Cenchrus ciliaris (buffel grass) and Melinis repens (red Natal grass) were generally present at low densities. Describing pastures in terms of frequency of a few species or species groups sometimes failed to capture the true nature of the pasture but plant abundance for most species, as density, herbage mass of dry matter or plant crown cover, was correlated with its recorded frequency. A quantitative description of an average pasture in fair condition is provided but it was not possible to explain why some species often occur together or fail to co-exist in Aristida/Bothriochloa pastures, for example C. ciliaris and E. bimaculata rarely co-exist whereas Tragus australianus (small burrgrass) and Enneapogon spp. are frequently recorded together. Most crown cover was provided by perennial grasses but many of these are Aristida spp. (wiregrasses) and not regarded as useful forage for livestock. No new or improved categorisation of the great variation evident in the Aristida/Bothriochloa native pasture type can be given despite the much improved detail provided of the floristic composition by this survey.

Full text
Abstract:
Measurements were made of the wool growth, body weight gain and diet of sheep grazing a saltbush pasture near Broken Hill, N.S.W. The experiment utilized a fenceline contrast in saltbush (Atriplex vesrcarra) density that was visible on Landsat imagery. It ran for five years (1976-1981) with a design of two pasture types by two stocking rates. Fleece weights varied from 3.9-6.0 kg/head and wool production from 0.6-2.9 kg/ha. Neither wool production per head nor bodyweight were substantially affected by stocking rate or pasture type. The composition and quality of the diets selected by sheep on both pastures were identical and of high nutritional value indicating their capability to accommodate differences in pasture composition. Pasture quality was not limiting between stocking rates or determined by the abundance of saltbush. Changes in pasture composition resulting from grazing and exclosure were small and of no significance.

Abstract:
This thesis investigates how small disturbances influence community structure in three permanent pastures. Small disturbances play an important role in providing spatial heterogeneity that permits new recruits to enter populations in closed sward communities, thereby promoting diversity and species co-existence. The thesis has four components: the first two are based on observation and measurement of the occurrence of small disturbances, molehills and dung pats, in three pastures. Within pasture seasonal changes in disturbance regime were related to changes in patterns of species abundance by multidimensional contingency table analysis. Dactylis glomerata, Agropyron repens and Taraxacum officinale increased in highly disturbed plots, whereas Holcus lanatus and Trifolium repens decreased. Invasion of molehills and dung pats was usually by rhizomes or stolons from surrounding plants. Seedling recruitment was rare: Trifolium repens was the only species dependent on small gaps for sexual regeneration. Patterns of species replacement on and around the disturbances were non-random. The third part of the thesis investigated the effects of selective removal of Lolium perenne, Holcus lanatus and Trifolium repens from the oldest and youngest pastures. Strong responses to the removal of these species were found only in grasses in the youngest pasture. This is consistent with the hypothesis that competition decreases over time because of niche divergence, but may also reflect biological accommodation to grazing pressure. The fourth part of the thesis investigated changes in species composition in simulated swards in response to different regimes of mowing, fertilizer and small gap creation. Species composition was strongly influenced by mowing and fertilization but was unresponsive to small gap creation.

Abstract:
In 2006 - 2008 \'Willow Creek\' winter wheat and \'Trical 102\' triticale were evaluated for biomass production and forage quality under grazing and hay systems in Montana. Forage cultivars of winter wheat and triticale were subjected to a single grazing event at three growth stages (vegetative, boot, or heading) in the late spring. Subsequent regrowth from each grazing event was harvested as hay. Growth of winter cereals was modeled with environmental conditions. Both cultivars reached 100% headed between accumulated growing degree day (base 5 C°) 1090 and 1245 (between July 7 and 13) during the three year trial. During this period, winter cereals experienced rapid forage growth, and grew 1.4 to 2.6 cm daily and produced 87 to 248 kg ha-1 daily. In two years, triticale had superior forage biomass compared to winter wheat. Forage quality of winter cereals was excellent at the vegetative stage of growth and declined until the final forage harvest dates. At all growth stages winter wheat and triticale had similar levels of forage quality. However, the rates of digestibility of winter wheat pasture and hay were greater than those of triticale. When grazed at increasing stages of maturity, winter cereals demonstrated variable forage regrowth yield and quality. Delaying grazing until later dates coincided with hot and dry growing season conditions and limited forage regrowth potential. Regrowth of grazed cereals declined in forage quality with advancing maturity. Nitrate concentrations were high enough to concern producers with pregnant livestock grazing in spring or when grazing regrowth. Grass tetany was found to be a potential risk to lactating livestock grazing early vegetative winter cereal forage. In a whole animal digestion trial, winter wheat hay was had similar digestibility when compared to traditional grass alfalfa hay, in a sheep maintenance diet. Winter cereals can offer producers a viable option for a pasture-hay system in Montana. Maximum total biomass was a single cutting of hay at anthesis and early grain development. Therefore, it will be necessary for livestock producers to consider total biomass, availability and cost of pasture and hay, and forage quality, when using a pasture-hay system in Montana.

Abstract:
The number of people on our planet is projected to rise to between 9.4 and 10 billion by 2050. Some estimates suggest that current levels of food production will need to double to feed this population. Increasing the intensity of food production on existing agricultural land will be a crucial element in meeting this goal, but practices associated with intensive management can cause biodiversity declines and erode the ecosystem functions that underpin production. My work explores agricultural intensification within the context of pasture-based cattle production. I focus on a variety of ecosystem functions supported by dung beetles (Coleoptera: Scarabaeoidea) and other dung-associated invertebrates. I investigate how variations in diversity, and chemical perturbations of veterinary anthelmintics affect the delivery of multiple ecosystem functions. I show that maintaining species-rich dung beetle assemblages has inconsistent benefits in providing multiple ecosystem functions. While dung beetles play an important role in supporting functioning in the short term, my work also reveals that their contributions may be less evident when considered over longer periods. Chemical perturbations caused by anthelmintic residues represent a significant threat to some invertebrate groups, but my experiments show that exposure does not always translate into an immediate reduction in ecosystem functioning. While use of anthelmintic products with relatively low toxicological risk did not cause obvious reductions in function, my work shows exposure can have significant consequences for the conservation of sensitive species. Overall, my work highlights the need for multigenerational studies, mathematical modelling, and careful consideration of sublethal effects to assess fully the risks of anthelmintic residues in the pasture environment. Furthermore, the emphasis on dung beetles (rather than other dung-associated invertebrates) in the existing literature neglects potentially important functional benefits provided by other taxa, such as earthworms. As the global human population continues to expand, it is important that we find sustainable ways to produce food while simultaneously conserving biodiversity. As loss of biodiversity in agricultural ecosystems does not always have functional consequences, it is important that wider justifications for conservation remain integrated into agricultural policy and practice.

Hawley, Tanya Joy. "Mechanisms Underlying Frog Occupancy Patterns in a Landscape Mosaic of Tropical Forest and Pasture." Scholarly Repository, 2008. http://scholarlyrepository.miami.edu/oa_dissertations/86.

Full text
Abstract:
Habitat modification is the primary cause of amphibian population declines worldwide. Some species survive in modified habitats whereas others become restricted to small, isolated forest patches. Although many studies compare species richness and composition between modified and intact habitats, the factors and mechanisms that maintain biodiversity in these landscapes are poorly understood. I asked how life history traits and habitat features influence interspecific variation in frog occupancy patterns in tropical pasture and forest. To identify mechanisms underlying occupancy patterns, I used experiments to examine how abiotic conditions in different habitats influence the vital rates of tadpoles. I also explored whether tadpoles use a carnivorous foraging strategy to improve performance in nutrient-poor, ephemeral pools in pasture. Although modified and intact habitats offer abiotic environments that differ in quality for frogs, pastures contribute to the maintenance of biodiversity in fragmented landscapes. I detected an equal number of species but substantially different assemblage composition in forest and pasture. Species that occurred in pasture had different traits than those in forest, including larger body sizes, larger clutch sizes, larger geographic ranges, and reproductive modes that depend on water. The occurrence of pasture-specialists was associated with habitat features at small spatial scales, whereas the occurrence of forest-specialists was associated with habitat features at small and large spatial scales. An experiment indicated that abiotic conditions in pastures may deter or facilitate adult movements to breeding sites. Behavioral selection of sites by two model species was consistent with tadpole performance. Tadpoles of a pasture-specialist performed well across the pasture-forest gradient, but abiotic conditions in pasture facilitated faster growth and development than in edge or forest. In contrast, tadpoles of a forest-specialist performed well only in edge and forest. Most tadpoles occupying ephemeral pasture pools were facultative carnivores or cannibals of eggs and hatchlings. Tadpoles may contribute to the regulation of assemblages in pasture pools, influencing the relative abundance and composition of species through differential predation on eggs and hatchlings. The study of factors and mechanisms that contribute to population growth or decline of species can facilitate understanding of assemblage-level patterns of amphibian diversity in modified landscapes.

Abstract:
This thesis examines the complex environmental, social, economic and political challenges surrounding sustainable land use of rangelands by European leaseholders in Western Australia. A study of historical, socio-economic and technological events, combined with the development of social values and policy, exposed a broad suite of factors that shaped pastoralism and grazing, and continues to influence development in these regions today. The thesis also explained how the emergence of the sustainable development paradigm is raising awareness of the ways societies define the issues of development, and the influence of this paradigm on attempts to shape change. Extensive changes in animal production systems have been made in response to complex factors driving change in pastoralism and grazing in recent years. In the Upper Gascoyne, the change to cattle has resulted in extensive changes in infrastructure and raised new hopes for viable production systems in the future. Station amalgamation or sale of stations to Government Departments have been key factors of change in this region. In the Mt Magnet region, wool production remains dominant. However severe drought conditions and declining wool prices are increasingly forcing change to production of feral goats or Damara sheep. Increasing conflict in the rangelands centred around competing claims to land and its use, against a backdrop of dry seasons and changing socio-economics, are escalating leaseholders' fears and concerns about growing community demands for multiple rangeland use. Government approaches now focus on multiple use of rangelands, providing incentives or opportunities to develop alternative methods of use for rangeland resources. However, environmental barriers to sustainable land use and diverse perceptions of sustainability continue to create difficulties for developing effective policies and strategies for change. There is now an urgent need for a paradigm shift in attitudes towards rangelands that promotes more sustainable uses for the land, a greater equality in sharing resources and constructive integration of the values of all rangeland stakeholders.

Abstract:
Agricultural production is currently at a crossroads due to the need to balance the requirements of climate, biodiversity, air quality, and access to food health, farmers' incomes and economic conditions. These demands are often controversial, and the goals of policy makers are contradictory. Sustainability in agriculture needs to be put into practice. The concept of sustainable agriculture is based on agro-ecology and a system approach and aims to promote sustainable, resilient, cost-effective and stable farming systems. Based on the analysis of the scientific literature and the current situation, the paper authors have concluded that a logical path to sustainability is integrated agriculture. It is a whole farm management system that allows farmers to identify opportunities and threats and act accordingly, while also taking into account the interests of consumers in their business. The paper aims to outline the role of integrated agriculture in the development of sustainable agriculture based on the analysis of the relevant scientific literature and the current situation. Integrated management is the knowledge-based management of all available resources integrated farms are able to provide climate benefits, provide more diverse (especially pasture) land management, farm animals have a higher quality of life and survival.

Abstract:
Research objective is to evaluate the change of ecological farm areas and cultivated cultures within the territory of Lithuania within the period from 2010 to 2014. In 2010–2014 the data from certification institutions (databases) were used for the purpose of evaluation of change of ecological farm areas, which provide all ecological farm areas declared and certified in Lithuania within the whole reported period and agricultural plants cultivated on the areas within the set period. ArcGIS software was used for demonstration of layout of ecological farm areas within the territory of Lithuania. It was established that the major areas of ecological farms analysed within the period were located in the North-East of Lithuania, less areas in the Northern and Southern parts of middle Lithuania. During the whole period the major planted acreage of the ecological farms was taken by meadows, pastures, perennial grass; these cultures annually made almost a half of the declared planted acreage. Less declared planted acreage of the ecological farms within the research period was taken by root plants and vegetables; area planted with the cultures usually made 1 per cent from all declared planted acreage of the ecological farms. Strong correlation exists between the areas of ecological farms and pastures (r = 0.70, when p = 0.0001), complex agriculture (r = 0.76, when p = 0.0001), transition forest stage and bushes (r = 0.85, when p = 0,0001), broad-leaved forests (r = 0.84, when p = 0.0001), needle-leaved forests (r = 0.72, when p = 0.0001) and mixed forests (r = 0.84, when p = 0.0001). Weak correlation exists between ecological farm area and agricultural areas with natural plant insertions (r = 0.47, when p = 0.0001).
