Abstract

A methodology for the evaluation of the conservation interest of river corridor vegetation is described and suggestions made for its improvement. Of the attributes used for describing and grading sites, species richness and site uniqueness proved more useful than species rarity, mainly due to variations in the quality of recording and season. Bryophyte data, although often ecologically more informative than vascular plant data, are rarely obtainable due to a lack of competent recorders. Inter-recorder comparisons are recommended as differences between them were a major source of variation within the data. Comparisons of data with those from other surveys must be approached with caution as differing definitions of sampling zones, recordable taxa, time of year, purpose of survey and even the state of flow of the river can all alter the recorder's perception of habitat and species abundance.
