Summary:
Marine macroalgae of the upper sublittoral zone are widely used for assessing
the ecological quality and long-term changes in a coastal ecosystem. The
Saronikos Gulf was considered as one of the most polluted areas of the Eastern
Mediterranean Sea. Along with the waste treatment plan of Psittalia in the late
'90s, the monitoring of Saronikos’ macroalgae began. Every year three seasonal
samples were collected by the destructive method from the sampling sites along
the Gulf’s coastline. The results revealed a clear reduction of both
nitrophilous algae and the overall algal coverage, suggesting a gradual
improvement in the trophic status of the Inner Saronikos Gulf. Nevertheless,
the populations of Cystoseira, which are considered to be emblematic species of
pristine ecosystems, were also reduced. This reduction of Cystoseira
populations is connected to sea-urchin overgrazing and habitat destruction. In
conclusion, a clear trend towards improved environmental quality was recorded
based on macroalgal populations; however, the increase of population and the
expansion of Athens metropolitan area towards eastern coasts of Attica could
jeopardize the progress so far with unpredictable consequences.
