Un paisaje pirenaico de prados y pastos: cambios recientes y perspectivas

Abstract

[ES] Los prados y pastos del Pirineo se pueden considerar comunidades herbáceas seminaturales a las que es posible aplicar formas de producción futura que se compaginen con la conservación. Diversos organismos internacionales, europeos, y los gobiernos autonómicos españoles las consideran comunidades interesantes bajo este doble aspecto. Los estudios del banco de semillas del suelo y del origen de la flora de los prados actuales, revelan claramente que la diversidad está muy relacionada con el mantenimiento de paisajes en mosaico. Los suelos sólo han ido incorporando semillas de prado en los primeros 10 cm pero a mayores profundidades se conservan las semillas de comunidades abiertas, típicas de los antiguos campos de cereal. Los pastos se extienden a superficies típicamente forestales por lo que su mantenimiento deberá consistir en un cuidadoso cálculo de cargas ganaderas, distribuidas entre animales de diversas especies y razas, y ocupando superficies adecuadas a lo largo de diferentes periodos de tiempo. Las nuevas demandas turísticas generan nuevas situaciones de intereses en las superficies comunales de pasto, y un reto futuro consistirá en adecuar correctamente los distintos tipos de demandas para que todas puedan satisfacerse sin que unas pocas acaben con las demás.

[EN] Pastures and meadows of the Pyrenees might be considered as semi-natural herbaceous communities that, in a short time, may be considered as types strongly related with the conservation. Several international organizations, as well as the European and the Spanish autonomic governments, have realized the big interest of these communities under this double point of view. Studies carried on the soil seed bank and on the origin of the current meadows flora, show a strong relationship between diversity and the mosaic landscape organization. The study of the superficial (10 cm) soil seed bank has showed a species composition related with the current meadows flora, but in deeper soil we find seeds of typical open communities as a trace of old cereal fields. Pastures occupy old forestry surfaces and it is necessary to calculate accurately the livestock capacity, distributed between different animal species and breed types through several seasons and surfaces. The new tourist demands originate new perspectives in the communal pastures. To adequate the combined development, avoiding the prevalence of certain demands to the detriment of the others, will be the challenge for the next years.
