“…These values are consistent with what has been observed in other Mediterranean islands and archipelagos, such as the Balearic Islands and the Tuscan Archipelago (Podda et al, 2011;Lazzaro et al, 2014) and in the continent, as Spain (Sanz Elorza et al, 2004).…”

“…The high disproportion of invasive taxa found between neophytes and archeophytes also characterizes other contexts such as the Balearic Islands (Podda et al, 2011) and the Tuscan Archipelago (Lazzaro et al, 2014). In the case of the Balearic Islands (14% of invasive taxa) and the Tuscan Archipelago (22% of invasive taxa), the proportion of such invasive entities is higher than in Sardinia and Corsica.…”

“…The American predominance featuring alien flora -invasive and not invasive-of Sardinia and Corsica, is a constant in many Mediterranean areas, both islands -such as the Balearic Islands (Podda et al, 2011(Podda et al, , 2010 (Arianoutsou et al, 2010). Other relatively important contributions to the exotic flora of Sardinia and Corsica, as for the other mentioned territories, come from Asia, from the Mediterranean basin and the African continent; with respect to the invasive flora, it is to be noted that the Mediterranean component is significantly reduced.…”

This article provides a comparison of the vascular alien flora of Sardinia (Italy) and that of Corsica (France), both territories belonging to the Western Mediterranean biogeographic subregion. The study has recorded 598 (90 doubtful) alien taxa in Sardinia (18% of the total flora) while 553 (87 doubtful) in Corsica (17%); six are new report to Sardinia and 27 to Corsica. A total of 234 taxa are common to both islands. Neophytes are 344 taxa (68% of the total) in Sardinia and 399 taxa (73%) in Corsica. The invasive component includes 64 taxa in Sardinia (13% of the alien flora) and 99 taxa (21%) in Corsica, 33 of them common to both territories. The total 740 alien taxa of Sardinia and Corsica are included in 93 families; being Fabaceae the richest. The comparison of the biological spectrum reveals that phanerophytes (202 taxa, 40%) are the most represented in Sardinia and therophytes (149 taxa, 32%) in Corsica. A study of the geographical origin shows supremacy of the American element in Sardinia (170 taxa, 34%) and in Corsica (136 taxa, 29%). The majority of taxa arrived as a result of intentional human introductions, mainly for ornamental use (247 taxa, 49% in Sardinia; 208 taxa, 45% in Corsica). Seminatural, agricultural and synanthropic are the most occupied habitats. These data show the need for joint action to stem the increasingly worrying phenomenon of the alien flora in order to reduce the negative effects on natural habitats and native flora.

“…Before the present update, the alien flora of Sardinia represented the 18.8% of the total flora (Podda et al, 2010) that constituted more than a twofold increase in less than 20 years (9.2% in Viegi, 1993). On this basis, it is obvious how the progress of invasive plants is becoming a major concern for native and threatened taxa protection.…”

“…The finding of new 68 alien taxa in 11 years corresponds to an increase of 18.1% from the Corsican 1996 list ( Jeanmonod et al, 2011;Natali and Jeanmonod, 1996) while Podda et al (2010) reported 40 new alien taxa for the Balearic Archipelago in confront From a nomenclatural point of view and for the attribution of the taxa to the plant families it was followed the on-line databases of The Plant List website (2010) and of the Med-Checklist website (Euro+Med, 2006-onwards). Concerning the validity of the plant families it was followed what is reported in the Angiosperm Phylogeny Group III (Chase and Reveal, 2009;Stevens, 2001-onwards) while for gymnosperms and pteridophytes the works of Christenhusz et al (2011aChristenhusz et al ( , 2011b.…”

Alien plants colonization, due to the fast spreading of highly invasive taxa, is more and more a serious source of concerns for habitat and species conservation. Apart direct in situ intervention, it is of major importance to acquire the best and up to date knowledge about alien taxa that currently threaten the integrity of wild and valuable environments. In this light, here is presented the update to the checklist of alien vascular flora of the island of Sardinia (Italy) on the basis of the new findings, nomenclatural adjustments, and revision of diffusion status of alien taxa. The checklist at present, consists of 541 taxa (84 doubtful) which represent 17% of the whole flora of the island; 22 taxa are new to the island and 7 of them for Italy. Neophytes represent the majority of the whole alien flora (301, 66% of the total) and, in confront to archaeophytes, gather nearly all invasive taxa (54 vs 4). The new findings are all neophytes. Phanerophytes (42%) are the most representative biological form and Americas represents the region that mostly contributes to the Sardinian alien flora (33%). Further analysis highlights that, in terms of number of taxa, highly anthropically impacted environments such as synanthropic (36%) and agricultural (23%) are the eligible habitats for most of the alien species in Sardinia while coastal areas and wetlands, beyond hosting a lower number of taxa, are characterized by the relative highest number of invasives.

The Mediterranean Basin is one of the biodiversity mega-hotspots of biodiversity, but it is also considered as one of the most disturbed areas, due to a legendary human occupation, mostly concentrated in coastal areas. These factors, together with a mild climate, explain the high impact of invasive alien plants in the Mediterranean coastline. The habitats subjected to saline influence are especially interesting and have been widely studied as species living there have developed, along evolution, special adaptations that make them unique and very valuable. This study aims to present how alien plant species behave when becoming invasive in coastal habitats of the Mediterranean Basin. Some alien invasive species outstand for their specificity regarding the habitat and pose a major challenge for environmental managers. Coming to understand their behavior can help to mitigate their impact and prepare for future invasions. The document focuses on making a comprehensive characterization, with special emphasis on germination behavior of this flora, that has become one of the most important threats for biodiversity in the Mediterranean context.
