Plants adjacent to access routes to sites of active beach clean-up were also considered a priority. Field work involved revisiting rare and scarce vascular plants at risk where precise pre-Sea Empress locational and population size data existed. Copies of previously completed population forms were taken into the field and the current extent of the plants checked. Previous information was incomplete, natural fluctuations in population size from year to year in annual species, lack of precision in many pre-1996 records, limiting survey effort to subjectively chosen selected pant populations may have led to a loss of significant data.
