The vascular flora of the Marine Protected Area of "Capo Carbonara" (SE-Sardinia)
This study aims at presenting an updated inventory of the vascular flora of the Capo Carbonara Marine Protected Area, including the Sites of Community Importance “Isola dei Cavoli, Serpentara, Punta Molentis e Campulongu” and partially of “Costa di Cagliari”, in Sardinia (Italy). A total of 653 taxa are reported, 84% of which are native (5% endemics) and 16% non-native (10%
neophytes, 6% archaeophytes). The native component includes 406 species, 135 subspecies, two variety and one hybrid, belonging to 75 families and 313 genera. The non-native taxa are 94 species, 13 subspecies, one variety and one hybrid, belonging to 40 families and 81 genera. Life-form analysis of native species revealed a prevalence of therophytes (49%) followed by hemicryptophytes (21%), geophytes (14%) and chamaephytes (7%). Therophytes (33%) fol lowed by phanerophytes (32%) are prevalent among the non-native taxa. Biogeographically,
among native species, the Mediterranean element is largely prevailing (81%), mainly consisting of Circum-Mediterranean (39%) and Euro-Mediterranean (27%) taxa, while the American ele ment (35%) prevails over the Mediterranean species (29%) among the non-native taxa. Among endemics, the Sardo-Corsican taxa are dominant (55%), followed by Sardo-Corsican-Tuscan Archipelago (14%) and Sardinian (10%) taxa
Dai balconi ai parchi urbani: buone pratiche per un giardinaggio consapevole
Prodotto nell’ambito del progetto LIFE15 GIE/IT/001039 “Alien Species Awareness Program”(ASAP), è un opuscolo di tipo tecnico-pratico che intende fornire alcune informazioni di base sulle piante esotiche invasive presenti in Italia nonché, seguendo le buone pratiche dettate nel Codice di condotta definito nell’ambito della Convenzione di Berna, proporre un numero non esaustivo di specie native da utilizzare in alternativa alle piante esotiche invasive inserite nella Lista di Rilevanza Unionale e per le quali vi è divieto di importazione, commercio, possesso, riproduzione, trasporto, utilizzo e rilascio in natura. E’ indirizzato a tutti coloro che sono coinvolti direttamente o indirettamente nella produzione, commercializzazione e impiego delle piante ornamentali: aziende florovivaistiche importatori di piante e tutti coloro che svolgono un ruolo nella progettazione e realizzazione di aree verdi quali gli Architetti paesaggisti, i Dottori Forestali, i Dottori Agronomi e a tutti gli appassionati di giardinaggio. La scelta di utilizzare specie autoctone nel verde urbano risponde anche all’esigenza di garantire una migliore tutela e conservazione della biodiversità negli spazi urbani

Analisi comparativa della flora vascolare endemica e subendemica di Corsica (Francia) e Sardegna (Italia)
Data concerning knowledge of endemic and subendemic vascular plants of Corse and Sardinia are
presented. Nomenclatural and distributional updating besides a comparison of biological and
chorological spectra has been realized.
The analysis of endemic component together with geografical, geological and bioclimatic data confirm
that Sardinian-corsican territories form an independent biogeographical province in which we can
identify two subprovinces in relation to the high number of exclusive taxa and peculiarities with abiotic
characters
Riferimenti bibliografici sulla flora vascolare sarda riportati nell’Informatore Botanico Italiano dal 1969 al 2004
The authors have beeen referring to works about Sardinian flora published
in Informatore Botanico Italiano. The works dates back to establishment of review to
2004. A flora list has been drown up on a database where there is a lot of information
on every single entity: the places where they have been found, the relative bibliographical
references and when it is necessary the nomenclatural updating. 1334 records wich
were studied in 136 works have been analysed. There are totally 610 entities of
Sardinian flora like the list shows
Flora and vegetation landscape of Molara Island (north-eastern Sardinia)
In the framework of a research program involving headlands and small islands, our attention was drawn to the island of Molara, situated in north eastern Sardinia. It is a granite outcrop, covering 3,498 km2 and with a coastline extension of some 10 km. Its flora has been the subject of study by various botanists who overall listed a florístic contingent of 402 taxa, 360 of which were identified by Picci. Our studies have recorded 384 taxa belonging to 83 families and 252 genera. Comparison of the present-day and previous data shows that 86 taxa are new, 285 are confirmed and 104 have not been rediscovered. The variations depends on the different uses to which the island has been put over the last 40 years, a period during which farming activity carne to a halt and stock rearing was reduced to a minimum. As regards modifications of the vegetation landscape, these are most evident in areas at one time cultivated or used for grazing, where we find numerous bushes and bush forms of Olea europaea L. var. sylvestris Brot., Rhamnus alaternus L., Phillyrea angustzfolia L., indicating that phytocoenoses are developing in the direction of more evolved formations.En un programa de investigación sobre cabos y pequeñas islas, nuestra atención se ha centrado en la Isla de Molara, situada en la Cerdeña norte oriental, de substrato silíceo, con una superficie de 3,498 km2 y una extensión de la costa de 10 km. La flora de la isla ha sido estudiada por varios botanicos que han identificado 402 entidades florísticas de las cuales 360 ya fueron determinadas por Picci. Los estudios actuales han permitido encontrar 384 especies englobadas en 83 familias y 252 géneros. Comparando la flora actual con la de hace tres décadas, 86 taxones son nuevos para la isla, 285 han sido confirmados y 104 no se han observado. Las variaciones dependen de los diferentes usos del territorio en los últimos 40 años, durante los cuales ha des-aparecido la actividad agrícola y se ha reducido al mínimo la actividad ganadera. Por lo que se refiere a las modificaciones del paisaje vegetal, éstas se hacen más evidentes en las zonas antes cultivadas y explotadas por la ganaderia, donde son frecuentes plántulas y formas arbustivas de Olea europaea L. var. sylvestris Brot., Rhamnus alaternus L., Phillyrea angustifolia L. y numerosos arbustos que indican como la fitocenosis está dando lugar a formaciones más evolucionadas
