Threats

The threats to the saramugo are those that strike most Mediterranean riparian ecosystems in our country.

The degradation of the habitat and water quality are mostly the result of direct or indirect human actions, either through water contamination by residues (urban, industrial, agricultural), or through resource exploitation (water retention and abstraction, extraction of inert materials), or through the exploitation of surrounding aquatic systems, resulting from agricultural and livestock-related activities.

In the case of the saramugo, its known ancestral distribution in Portugal was always limited to the basin of the Guadiana river, whose flow regime is buoyant and where drought periods can be very intense. In these cases, water systems are weakened in the face of anthropogenic pressures, which are potentiated by water deficits.

In the saramugo Action plan, edited in 2014 by the ICNF, the mains threats to the saramugo are listed, among them the degradation of water quality due to intensive grazing or effluent discharges, extraction of inert materials, construction of dams, destruction of riparian vegetation and the spread of exotic fish species.

Check out the main threats described in detail and how they negatively impact the saramugo in the menu on the right.
