Tree invasions in Italian forests

2022

Many forest tree species have been moved outside their native range to provide goods and services elsewhere, but some of them have become invasive, causing negative impacts on biodiversity and human activities. The assessment and knowledge on the degree and scale to which forest ecosystems are invaded by non-native trees is of paramount importance for tailored policies and strategies aiming at forest conservation. By analyzing main databases and literature and applying a four-level scale of invasion (not currently invaded and with low invasibility; potentially invasible; moderately invaded; massively invaded), we assessed the current and potential occurrence of twenty-five invasive non-nati…

Are Sicilian forests at less risk of invasion by alien plants?

Climate change could facilitate the spread of invasive alien plants by making plant communities and individuals weaker and less competitive. Indeed, alien plants are generally more adapted to the rapidly changing environmental conditions that are being determined in the coming decades. Moreover, while alien plants have, until recent years, mainly affected synanthropic communities and man-made habitats, they are increasingly able to affect also more complex natural communities such as forests. The talk will show some Sicilian cases.

Making smart use of woody alien plants

It is unquestionable that some alien woody plant species are a major issue for biodiversity conservation. However, being alien species generally adapted to warmer conditions than autochthonous/local ones, they could be particularly suited to cope with the new environmental and climatic conditions that are also forecasted in the coming decades in Sicily. This poses an issue that is not easy to deal with, whether trying to use these species for the advantages they could bring, for instance in the new reforestation activities, while avoiding them becoming a serious problem for biodiversity conservation in natural and seminatural areas. Here, we present three study cases of non-native tree spec…
