Estudio de las comunidades de interés pascícola en un puerto de montaña: I. Estructura y valor pastoral

Abstract

Studies of grazing plant communities in mountainous areas: I. Structure and grass quality. The study of the structure of the mountainous grassland communities, as the main factor involved in the ingestive behaviour of herbivores, is presented in this work. The pressure on these communities depends on the selection exercised by the grazing animal and this, in turn, depends on the plant value or pastoral value for the herbivore. The "complex" method was used to determine this value. The results are compared with those of other authors. The "life forms" based on Raunkiaer's classification complete this study of the vegetal communities, defined from the point of view of their pastoral value.
