Abstract

This paper provides a checklist of exotic flora on the island of Sardinia (Italy) with a total of 482 taxa which represent 18% of the flora of the island; 29 taxa are new to the island and 9 of them for Italy. Most of these taxa (289, which represent 62% of the total) are neophytes and 173 (38%) are archeophytes, while new events are all related to neophytes. Among all neophytes, 44% are naturalized, 39% casual and 17% invasive. The archeophytes include a 55% of naturalized taxa, 44% casual and 1% invasive. The category of invasive accounts 11% of the total alien flora. The analysis of the checklist confirms phanerophytes as the most represented biological form (40%), with the American origin prevalent among all species (30%). Further analysis have been conducted in order to verify the impact on different ecosystems and the most vulnerable habitats to the phenomena of neocolonization are agricultural (32%) and sinanthropic (28%), followed by wetlands (11%) and coastal (10%).
