Shedding light on typical species: Implications for habitat monitoring
2021
Habitat monitoring in Europe is regulated by Article 17 of the Habitats Directive, which suggests the use of typical species to assess habitat conservation status. Yet, the Directive uses the term “typical” species but does not provide a definition, either for its use in reporting or for its use in impact assessments. To address the issue, an online workshop was organized by the Italian Society for Vegetation Science (SISV) to shed light on the diversity of perspectives regarding the different concepts of typical species, and to discuss the possible implications for habitat monitoring. To this aim, we inquired 73 people with a very different degree of expertise in the field of veget…

Contribution to the knowledge of Mediterranean wetland vegetation: Lemnetea and Potamogetonetea classes in Western Sicily
2021
The freshwater aquatic vegetation of the Lemnetea and Potamogetonetea classes in Western Sicily was surveyed and analyzed. 85 lakes and small pools were investigated collecting 147 phytosociological unpublished relevés to integrate the very scarce available data (only 3 relevés). By applying statistical analyses on abundances data and on the bases of physiognomy and dominant species, two alliances (Lemnion minoris and Stratiotion) and four different coenoses have been identify for the Lemnetea class; while 11 associations, assigned to two orders (Potamogetonetalia pectinati and Callitricho hamulatae-Ranunculetalia aquatilis) and four alliances (Potamogetonion, Nymphaeion albae, Ranunculion …
A methodological protocol for Annex I Habitats monitoring: the contribution of Vegetation science.
2016
The methodological foundations of the recently published Manual for Annex I Habitats monitoring in Italy, edited by the Italian Institute for Environmental Protection and Research (ISPRA) with the scientific support of the Italian Society for Vegetation Science (SISV), are here presented, discussed and related to the most consolidated and acknowledged scientific advances in the field of Vegetation science. The proposed methodologies aim at offering simple, yet effective, protocols and procedures towards a harmonized data collection, by way of standardized and shared technical tools, resulting in comparable evaluations of the conservation status of Annex I Habitats. The methodological framew…
