At the first meeting of the Nutrition Sub-Group on Animal-Vegetation Relationships at Clermont-Ferrand, September 1995, it was decided to identify research needs, as perceived by European researchers. Responses from 23 researchers from seven countries, Belgium, Germany, Greece, Ireland, Italy, Scotland and Spain, carried out by postal survey, are summarised. The overall aim is to understand animal-vegetation relationships, to improve methods for productive and protective use of grazing land resources and to protect the environment and rural socio-economic fabric. Responses are assembled under eight classes based on research emphasis, animal, vegetation, landscape ecology, sylvopastoral systems, socio-economic, supplementation at grazing, farm management, methodology and farming decision making aids.
