Despite the fact that it used to be a malaria-risk area which became a scourge for the peasants until the first decades of 1900 and was, therefore, reclaimed several times, the so called Earl’s Marsh has been included in the Sites of Community Importance (SCI) of “ Rete Natura 2000” for its interesting and distinctive natural environment. The marsh periodically hosts salty grasslands with black bulrush, fat-leaved plantain (plantago crassifolia), limonium serotinum and limonium virgatum. Along the canals grows the luxuriant marsh cane, the bulrush and many other typical species of these lands, such as the marsh orchid and aquatic orchid.
