Abstract

Analysis of Competitive Interactions in Grassland Stands by a Population Dynamical Model The potential yield of permanent grassland is highly influenced by dynamical interactions within its plant species. The possibility to recognize and to quantify these interactions opens a wide field of applications in grassland management. A mathematical simulation model was chosen to meet this aim. The base of the model is a simple population dynamic arrangement. The competition between the species or species groups is described by a linear function. A long time trial is used as a data base. The productivity and the floristic changes in this trial were recorded for 12 years. By reason of the limited data base the species were aggregated into 5 groups consisting of species with similar behaviour. The model proofed to be useful, to simulate the important interactions between the species groups and to quantify their significance with regard to the dynamic development of the grassland. Because of the small data set used in the sample, the model is limited in its validity. The model can be improved by incorporation of a larger data base.
