Rocky shore algal data from North Adriatic Sea (Piran) in 2006

Benthic macrophyte samples were collected from 51 sites along the Slovenian rocky coast. The aim of the study was three-fold: (1) to select sampling points for a surveillance monitoring programme, (2) to confirm water body boundaries proposed by the Slovenian Ministry of Environment and Spatial Planning and (3) to assess the preliminary Ecological Status Classes (ESC) within the European Water Framework Directory.
