Monitoring the invasion of an exotic tree (Ailanthus altissima) (Mill.) Swingle with Landsat satellite time series imagery in urban forest.

In the Mediterranean area, one the most threat tree to various ecosystems is Ailanthus altissima (Mill.) Swingle. This is an aggressive invasive species common in natural and semi-natural habitat. Monitoring and mapping of invasive species is an important information for the conservation and management of ecosystems. The study of distribution and diffusion of invasive species are useful to assess their environmental impacts, formulate effective control strategies, and forecast potential spread. The main target of this work is to examine the feasibility of mapping the expansion of A. altissima using remote sensing techniques in a highly complex urban forest setting. Remote sensing has been a…

Pianificazione per la gestione delle risorse pastorali e interventi di miglioramento dei pascoli: strumenti per la salvaguardia dei boschi montani mediterranei

Data analysis on extinct and living Picidae in Sicily and Calabria (Southern Italy).

Some species of animals related to forest habitats have disappeared or greatly decreased in the first half of the last century. However, during the second half of the last century the forest areas have increased and many forests have been protected. This produced conditions for a re-colonization or reintroduction of extinct forest animal species. The present study is a complete overview of records of extinct and still living Black Woodpecker Dryocopus martius, European green Woodpecker Picus viridis, Middle spotted Woodpecker Dendrocopos medius and Lesser spotted Woodpecker Dendrocopos minor in Sicily and Calabria (Southern Italy). This study was carried out to show that these woodpeckers, …
