Title: Biological report of the 1991 coastal and estuarine survey from Crosby to Glasson
Author: Elizabeth Potter
Document Type: Monograph
The coastline from Crosby to Glasson was divided into 9 stretches, on the basis of individual uniformity, i.e an individual stretch consisted of fairly consistent substrates and exposure levels throughout. A sampling site which was deemed typical of the stretch was selected for monitoring purposes. The stretches and sites are listed in Appendix B. Seven estuaries are covered in this baseline survey. Sample points Were selected to represent the different types of habitat available throughout the salinity regime. Again, these are listed in Appendix B. The coastline and estuaries covered in this report- are particularly susceptible to chance, as the sandy and muddy substrates typically found in this area are the most mobile of sediments and can vary greatly according to season. Instead, the use of a combination of techniques can more effectively sample a changing beach profile or new sediment deposition. There is also increased scope for inclusion of a wider range of habitats within a site, through the use of a variety of sampling methods. Of the methods used, the following were the most successful and are recommended for future surveys in this area.
