These summary statistics and analyses are based on the European vascular plant dataset published in November 2011.
Three groups of vascular plants have been assessed, totalling 1,826 species among which 467 have been identified as threatened with extinction. Species listed in policy instruments have a high number of threatened species with at least 44.9% at European and 47.3% at EU 27 level. A further 9.5% are classed as Near Threatened. Of the crop wild relative species assessed, at least 11.5% are threatened at European level and 10.5% in the EU 27 member states, with another 4.5% that are Near Threatened. The group of aquatic plants shows that at least 6.6% of the species in Europe and 7.2% in the EU 27 are threatened with extinction. Moreover, 7.4% are Near Threatened.
By comparison, 44% of freshwater molluscs, 37% of freshwater fishes, 23% of amphibians, 19% of reptiles, 15% of mammals and dragonflies, 13% of birds, and 9% of butterflies are threatened, groups that have been comprehensively assessed in Europe. Additional European Red Lists assessing a selection from species groups have shown that 20% of terrestrial molluscs and 11% of the saproxylic beetles are also threatened.
Looking at the population trend, it is noted that 38.4% of the policy plants, 15.8% of the aquatic plants and 10.9% of the crop wild relatives are declining. But more interestingly it needs to be noted that the population trend is unknown for 48.2% of the crop wild relatives, 36.7% of the policy plants and 18.6% of the aquatic plants.
The main current threats emerging in the analysis were: Overgrazing, recreational activities, tourism and urban development, wild plant collection, invasive alien species, natural system modifications and pollution.
