Effects of oil and clean-up of oil from the Sea Empress on the nationally rare and scarce vascular plants of Pembrokeshire
This dataset is made up of the results of an investigation into the impact of the Sea Empress oil spillage and its clean-up on populations of some of the rare and scarce vascular plants that were well recorded in Pembrokeshire prior to the pollution incident. The purpose of this data capture was to reassess the population size of selected nationally rare and nationally scarce vascular plants of the Milford Haven waterway and the South Pembrokeshire coast.

Plants that had potentially been in direct contact with liquid oil or grew in situations where oil contaminated salt spray was likely to have occurred were targeted for resurvey. 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.
