Summary
The floristic composition of a lawn is studied by means of permanent plots over ten years. Observations show that changes in the life history behaviour of certain species (Trifolium repens, and Sagina procumbens) have important effects on the vegetation dynamics of the lawn. These changes are ascribed to senescence and possibly a pathogen. Numerical classification (divisive information analysis) is used to define suitable classes for transition matrix simulation of grassland succession. The influence of life history changes and catastrophic drought is incorporated by estimating appropriate transition matrices. The limitations of the approach due to spatial patterns are emphasized.
