Popis:	Increase in recreational demand on the countryside makes the monitoring of resulting change in vegetation of value, especially in areas of recognized ecological importance. Methods are described for an initial survey of trampling pressure and soil compaction, and their effects on both the soil environment and the plant community structure. With reference to a dune slack habitat the response of the vegetation to trampling levels is assessed by linear regression analysis. Variation in diversity is noted together with changes in the ratio between monocotyledons and dicotyledons. Occurrence indices may be used to identify the species resistant to trampling; these, in general, are found to adopt a hemicryptophytic or therophytic growth form. Such studies can make a useful contribution to field investigations for older secondary school and undergraduate students, and provide starting points for further detailed investigations.
