Topic 1: BIODIVERSITY AND CONSERVATION SCIENCE: CONTRIBUTING TO MANAGEMENT
EEI is applicable only at Sts. 1, 2, 3 where macrophyte biomass was higher than 30%.
However, the classification is the same only at St. 2 (Alberoni Ottagono) whereas the
assessment of the other two stations differs even of two classes: St. 1 (S. Nicolò) is
assessed as “Moderate” and St. 3 (Lido watershed) is assessed as “Bad”. In fact, that
index is mainly based on macrophyte coverage whereas MaQI takes into consideration
mainly the presence of high score taxa and their relationship with some environmental
parameters and pollutants.
Conclusions – Macrophytes are very sensitive to the ecological conditions of
transitional waters and some indices can supply a very useful tool both in their
monitoring and management. In fact, the presence/absence of high score taxa such as
angiosperms and many macroalgae is strongly related to the environment trophic state
and pollution level. Therefore, the preservation or restoring of angiosperm meadows
should be the first objective for the transitional system management.
