Habitat use by indigenous grazing ungulates in relation to sward structure and veld condition [PDF]
Journal of the Grassland Society of Southern Africa, 1990 The objective of this study was to examine the relationships between the habitat requirements of different wild ungulate species, sward structure and veld condition. Veld condition score was correlated with sward height: habitats with high condition scores were dominated by tall grass species, whereas habitats with low scores were dominated by short ...

Effects of sward structure on herbivore foraging behaviour in a South African savanna: An investigation of the forage maturation hypothesis [PDF]
Austral Ecology, 2006 The grass layer of savannas is characterized by strong temporal and spatial heterogeneity in the quantity and quality of forage. Besides this, there is strong variation in other aspects of sward structure, here defined as sward chemistry, morphology ...

The role of grazing in creating suitable sward structures for breeding waders in agricultural landscapes [PDF]
Livestock Science, 2005 International audienceFrench wet grasslands support important populations of lapwings and others waders. Grazing management is a key issue in the use of grasslands by these birds since they are very sensitive to sward structure (height and heterogeneity).

Mechanistic simulation of the vertical structure of mixed swards
Ecological Modelling, 2002Abstract The vertical structure is an important feature of mixed swards, as it influences the inter-species competition for light, as well as the patterns of grazing. Although the experimental measurement of the vertical sward structure is relatively straightforward, the mechanistic and dynamic modelling of the leaf density and lamina density ...

Structure of Tall Fescue Swards and Intake of Grazing Cattle
Agronomy Journal, 1990AbstractModels of grazing systems need logic that estimate herbage intake of livestock from physical and chemical properties of the sward. Changeover designs were used to study the effects of sward structure of tall fescue (Festuca arundinacea Schreb. cv. Kenhy) on ingestive behavior of grazing cattle. Fourteen (Tl), 21 (T2), and 28 (T3) days of growth
