  • Note: Environmental asset results are provided for the main scenario (discount rate 3% and average prices of 2010), considering the average results of 567 silvopastoral farms. S1j to S4j refer to the four potential silvicultural models applied to each one of the j species.

  • a Other vegetation includes grazing resources in treeless shrubs, grassland, crops, and other forest species.
