Natural grasslands have a very large range of diversity both in terms of botanical composition, and with respect to edaphic and climatic conditions, in temperate and tropical regions. Moreover, grasslands are subjected to a wide variety of defoliation treatments according to management plans. This diversity of conditions leads to large temporal and spatial variations in sward structure: i.e., botanical composition, plant morphology and architecture, plant growth habits, which make it difficult to use a diagnosis of the sward state to predict either its growth potential or its ability to be grazed and to provide adequate feed for animals.
