Descripción
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. Extremadura dehesas surface is one million hectares with 95% of Q. ilex. Objective was to identify optimal stocking rate. A simulation model has been used to determine Iberian pig and dry cows stoking rate in Extremadura. Model runs with daily weather data from Extremadura Station Network, soil from Extremadura soil data base, and tree cover from the Third National Forest Survey. A data base was build for each input and visualized using ArcGis. All simulated pasture average yield was 3615 kg ha-1 and the acorns production was 249 kg ha-1. The model estimates that optimal stocking rate ranges from 0.3 to 0.8 Iberian pigs and from 0.1 to 0.9 cows ha-1.
