Développer, maintenir et pérenniser le potentiel des prairies permanentes : outils et techniques

Abstract : Applying the principles of functional ecology helps better predict the services which can be provided by permanent grassland. Farming practices and environmental characteristics influence the functional composition of grassland. Functional plant types have a generic effect on forage services which can be assessed. 13 types of grassland composed of distinct functional types were defined based on 1,283 sample grassland fields located on 8 sites. This approach was validated by checking 8 Ellenberg indicator values (used to evaluate environmental characteristics and farming practices) against climatic data and descriptive data for farming practices. The interest of a functional approach is discussed as a means of understanding the structure of plant communities, estimating the effect of changes in climatic conditions and farming practices, and predicting input services and services not included in farm income.
