The impact of recreation on the ecology and amenity of semi- natural areas: methods of investigation used in the Isles of Scilly

Questionnaires in the form of maps were used in the Isles of Scilly with the aim of developing quantitative and objective techniques for studying the effects of visitors on semi-natural areas. Maps were prepared of intensity of visitor use and distribution of various activities; these were compared with maps of plant communities. In addition photographic, observational and electronic people-counter records were made along transects and compared with vegetation and soil data using partial correlation analysis. The results are discussed and indicate that questionnaire-maps and data from the recording devices provide a useful basis for making management proposals.
