Abstract

Dehesa or montado is a Mediterranean agro-silvo-pastoral system characterized by the presence of trees, Quercus ilex and Q. suber, and annual pastures. Acorn production is used to feed pigs, and pasture is grazed by cows, sheep or goats. The surface area of Extremadura dehesas accounts for one million hectares, 95 per cent of which is Q. ilex. The objective was to identify the optimal stocking rate. A simulation model was used to determine stoking rates for Iberian pigs and dry cows in Extremadura. The model runs with daily weather data from Extremadura Station Network, soil from Extremadura soil database, and tree cover from the Third National Forest Survey. A database was built for each input and was displayed using ArcGis. Simulated average pasture yield was 3615 kg per ha and acorn production was 249 kg per ha. The model estimated that the optimal stocking rate ranges from 0.3 to 0.8 Iberian pigs per ha and from 0.1 to 0.9 cows per ha
