Table 2: Ecological quality values calculated for <strong>the</strong> six geomorphological relevant situations in reference conditions The EQR <strong>of</strong> every sector <strong>of</strong> coast to be evaluated was calculated based on <strong>the</strong> relation between <strong>the</strong> EQV obtained in <strong>the</strong> study site and <strong>the</strong> EQV in <strong>the</strong> reference sites corresponding to <strong>the</strong> same “geomorphological relevant situation”. Therefore, <strong>the</strong> EQR <strong>of</strong> a coast is calculated according to <strong>the</strong> following formula: where: Situation Type <strong>of</strong> coast N/A EQV 1 Decimetric blocks Artificial 12,06 2 Low coast Artificial 11,86 3 High coast Artificial 8,00 4 Decimetric blocks Natural 12,20 5 Low coast Natural 16,61 6 High coast Natural 15,25 i : situation EQVssi: EQV in <strong>the</strong> study site for <strong>the</strong> situation i EQVrsi: EQV in <strong>the</strong> reference sites for <strong>the</strong> situation i li: Coastal length in <strong>the</strong> study coast for <strong>the</strong> situation i The EQR is a value quoted from 1 to 0. We classify <strong>the</strong> range <strong>of</strong> values in 5 categories <strong>of</strong> disturbance and status (table 3) that are expressed in five different colors in <strong>the</strong> maps: blue for high, green for good, orange for moderate, yellow for poor and red for bad ecological status Table 3: Degree <strong>of</strong> disturbance and ecological status for different intervals <strong>of</strong> <strong>the</strong> Ecological quality ratio EQR Disturbance Status >0,75 – 1,00 No or very minor High >0,60 - 0,75 Slight Good >0,40 - 0,60 Moderate Moderate >0,25 - 0,40 Major Poor 0,0 - 0,25 Severe Bad ACTES DU DEUXIEME SYMPOSIUM MEDITERRANEEN SUR LA VEGETATION MARINE (ATHENES, 12-13 DECEMBRE 2003) 151
PROCEEDINGS OF THE SECOND MEDITERRANEAN SYMPOSIUM ON MARINE VEGETATION (ATHENS, 12-13 DECEMBER 2003) 152 EXAMPLE This methodology has been applied to <strong>the</strong> coast <strong>of</strong> Catalonia. Data was collected in spring 2002. The geomorphological parameters were evaluated in year 2001, toge<strong>the</strong>r with <strong>the</strong> geomorphological and community cartography <strong>of</strong> <strong>the</strong> reference sites. Here, we present <strong>the</strong> EQR corresponding to different regions, although it can also be obtained for municipalities or o<strong>the</strong>r geographical or management-based units (Fig. 3). The result <strong>of</strong> <strong>the</strong> EQR for <strong>the</strong> littoral regions in Catalonia in year 2002 shows that <strong>the</strong> ecological status <strong>of</strong> <strong>the</strong> nor<strong>the</strong>rn coast is high, while <strong>the</strong> center and <strong>the</strong> south coast have a moderate status, except for <strong>the</strong> region <strong>of</strong> “Tarragonès” with a good status. The region “Baix Llobregat” has not been evaluated since its shoreline is completely sandy. CONCLUSIONS The cartography <strong>of</strong> <strong>the</strong> littoral communities permits to know <strong>the</strong> distribution <strong>of</strong> <strong>the</strong>se communities along <strong>the</strong> coast and <strong>the</strong> monitoring <strong>of</strong> <strong>the</strong> ecological status <strong>of</strong> coastal waters within <strong>the</strong> WFD monitoring programs. The sampling <strong>of</strong> data is relatively quick and, as a visual method, it is non destructive. It is also important to point out that is continuous and every piece <strong>of</strong> rocky coast can be evaluated. Never<strong>the</strong>less, coasts devoid <strong>of</strong> any kind <strong>of</strong> macroscopic vegetation cannot be evaluated (e.g. sandy shores).
