ResumenLittle has been published about the utilization of oaks as pasture, and even less about their importance in Spanish rural life, from prehistory through the 20th century. Browsed oak ecosystems could continue to play an important role due to their ability to resist climate change. The “bardal” consists of Quercus pyrenaica that has been converted by browsing/grazing into a permeable green carpet. This pasture type is not only able to take advantage of intense rainfalls, but can also reduce evapotranspiration, so important when the oak is a tree. In addition, the “bardal” prevented erosion and accumulated water in its powerful colluvium. These areas are typically now eroded and gravelly, and are called “rañas” by geomorphologists. While the “bardal” is a typical grazed oak found in the mountains on the Atlantic side of Spain, the “sarda” is characteristic of the Mediterranean side. It is dominated by kermes oak (Quercus coccifera), a small bush, evergreen and strongly ramified, with a hemispherical shape capable of withstanding the dry months of summer and re-sprouting during the heavy mid-summer and autumn rains. It is a pasture type that was created by Valencian goatherds, beginning in the geologic past when the sarda was spread throughout the Ebro Valley to Navarra, Aragó and Catalunya. Reforestation with pines planted in the 1950s and 1960s, coupled with the forced abandonment of traditional grazing practices and dwindling numbers of goat herds, led to an increase in forest fire.
