Report on medium-term effects of the habitat protection and restoration activities of the LIFE Project “Maintenance of the habitats of the Macalube of Aragona” (Sicily, S Italy)

The Site of Community Importance (SCI) “Macalube di Aragona” is prone to severe desertification risk. In fact, its vegetation is disturbed not only by cyclic soil movements resulting from sedimentary volcanism, but it is strongly influenced by the hostile properties of the clayey substratum (prone to intense linear erosion, badly aired, rich in salts, etc.), the long drought period (ca. 4 months) and by the long-lasting history of human pressure. Both stress and disturbance factors influence progressive succession processes, so that the most “mature” local plant communities are () the chenopod shrublands referred to Salsolo-Peganion (habitat 1430 according to 92/43 EU Directive) and the hal…

Emergenze vegetali dell'Isola di Lampedusa

Per la peculiarità storica, geografica ed ambientale l’Isola di Lampedusa, e vista l’estrema frammentarietà delle formazioni preforestali, l’esiguità dei popolamenti (e degli individui) delle specie legnose assumono un valore scientifico e conservazionistico particolarmente elevato. Per queste ragioni è stato fatto un censimento eseguito con strumentazione GPS. Sull’isola crescono diverse specie di rilevante interesse conservazionistico, numerose sono infatti le specie endemiche, esclusive, rare e/o a rischio di estinzione perché legate a habitat molto vulnerabili e localizzati. A questa ragione d’interesse generale per questi taxa si somma il fatto che buona parte delle specie arboree tipi…

Combining ecological engineering and plant conservation on a Mediterranean islet

This paper reports the results of a bioengineering intervention within the Mediterranean Basin carried out at Lampedusa Island (Strait of Sicily) on the “Spiaggia dei Conigli”, the only sand shore of all Sicilian territory where the sea turtle Caretta caretta lays its eggs every year. The erosion of the steep slope over the beach itself caused sensitive changes in the grain size of shore’s sediment and reduced the area of the beach with fine sand suitable for C. caretta oviposition. In order to reduce surface water flow and to stop erosion, several bioengineering options were adopted using only native plant species to preserve local botanical heritage and to prevent the local extinction of …
