The dataset contains the UTM coordinates (European Datum 1950) of Pennisetum setaceum (Forssk.) Chiov in Andalusia (Spain).

The dataset contains values of the invasion risk analysis (see the Australian and New Zealand method in Pheloung et al. 1999) of 177 naturalized alien plant species in eastern Andalusia. When the risk analysis was positive, the source and quote are also provided. In addition, native distribution, habitat potential (based on the EUNIS classification) and coordinates are provided.

Presence/absence data for spermatophytes (from 2009 to 2015, 1921 circular plots of 100m diameter), potential natural vegetation map, vegetation classification map, occurence data for Aenocarpus, Aeonium, and Opuntia, endemic species diversity (gridded), species occurence data on lava flows (including mosses and lichens) and roadsides, occurence of other invasive species, data on herbivory and fire, treeline, facilitation

The dataset contains records of vascular plants collected in the lower valley of River Sabor (NE Portugal) in the scope of the long-term Ecological Monitoring Program (PME) of the Baixo Sabor Hydroelectric Dams (AHBS), promoted by EDP – Energias de Portugal, S.A, to assess the spreading capacity of exotic invasive species in the work front (dam structures and complementary works – dam yards, quarries, heaps, work front and road accesses) during the dams construction period (2010-14). Plant inventories were collected in line transects performed on foot, in all work front sites, along 42 km upstream, in the Sabor valley, and in the Vilariça stream.

Undaria pinnatifida was observed for the first time in the Mar Piccolo in April 1998, settled on the docks near the small fishing boat harbour. A systematic campaign of measurements was carried out from December 2000 to November 2002 and from December 2006 to November 2007 to follow the development of this non-indigenous species population
