The site_pt layer includes a point for every site in the sampling frames (flats and fringe) in use since 2001, the fringe orphans, and the sites outside the SVMP study area in south Puget Sound. In addition, there are points for three sites from the site_poly_special layer that do not coincide with the SVMP sampling frames (outf455, outf457, outf458). These three additional sites have been sampled but the surrounding SVMP sites have not been sampled. Points were not included for sites outside the SVMP frames where the surrounding SVMP sites have been sampled.
