What are the sic?
The Sites of Community Interest or SIC hosting habitats and species which have considerable significance for conservation because rare or threatened. They have been set up thanks to the "Habitat" Directive of '92 with the aim of establishing, within the European Union, a network of Special Areas of Conservation (SAC).
Protection of amphibians species.
The regional law n.23 / 1998 and the nationa law No. 503/1981, Annex II, which incorporates the Berne Convention and Annex II and IV of the "Habitats" Directive 92/43 / EEC, prohibit the capture, the killing and trade in species of amphibians in Sardinia.
How you define a biological indicator?
Organism (or biological system) used to evaluate a modification of the environment.A biological indicator is then represented by a species, animal or plant, whose presence and state of health is strongly linked to the quality of the environment in which it lives.
A part of the Municipality of Seulo (36.2% of its territory) is part of the area of the "Mounts of Gennargentu" which constitutes the largest of the Sites of Community interest (SCI) in Sardinia.
ENVIRONMENTS AND SPECIES TO BE PROTECTED
* This communication has been produced as part of the research project entitled "Project of monitoring the 'batracofauna' presents in aquatic habitats,within the territory of the High Flumendosa's Valley of Seulo and the natural reserve of Mount Arcosu" developed by the business network "macrostigma" through a research grant financed from the resources of POR SARDINIA F.S.E. 2007-2013 - Regional competitiveness and employment, Axis IV Human capital, lines of activity l.1.1. and L.3.1 .
According to Standard Forms, compiled for the European Community by the Region, such SIC manifests a suitable habitat to accommodate amphibian species included in Annexes II and IV of the Habitats Directive which therefore requires the designation of special areas of conservation and strict protection.
The territory of Seulo has a rich fauna, considering the amphibian species it houses. almost all are insular or tyrrhenian endemisms ,that is species found exclusively in Sardinia or in the Tyrrhenian sea. Some, like the Sardinian Euprotto and Discoglossus , are at increased risk of extinction and are classified as Endangered and Vulnerable in the Red List of the World Union for Conservation of Nature (IUCN 2013).
Amphibians are excellent bio-indicators of the state of health of ecosystems because their life cycle is very sensitive to environmental disturbances. The evaluation of the health status of populations of amphibians in the area of Seulo is therefore a useful instrument for assessing the quality of the environments that make it up.
