Modeling grazing intensity of grassland
Gregory Egger, Key note
The land use model (program "Grass Pre") was developed to simulate the grazing intensity of alpine pastures. Model input parameters are 1) the total energy requirement of all livestock of the whole study area, which is calculated from i) the sum of all different types and number of livestock, ii) milk production, iii) duration of the grazing period and 2) the "attractiveness" of each polygon, for which the yield per ha is used as an indicator. The model output parameters are the used yield per hectare and the land use intensity of each polygon (see application example, presentation S. Aigner).
