Solanum elaeagnifolium (Solanaceae) Invading One in Five Natura 2000 Protected Areas of Greece and One in Four Habitat Types: What Is Next?

Invasive alien plants have severe impacts on biodiversity and ecosystem services worldwide. To assess the invasion of Solanum elaeagnifolium Cav. (a major invasive plant; Solanaceae) in Greek protected areas (PAs), we conducted an extensive drive-by survey across country crossing half Natura 2000 sites. The occurrence data were then linked GIS with (i) boundaries sites, (ii) mapped habitat types invaded (iii) Corine land cover, from which calculated services. results showed that approximately 24% investigated PAs by S.elaeagnifolium to varying degrees extension density populations. A variety 29 different Annex I Directive 92/43/EEC (including a priority seven national importance) found be (one four present Greece). In recorded human activities/threats mostly related agricultural activities high intensity, while potential service provision was relatively low for category regulating Our study provides first nationwide report distribution S. sites Greece, providing baseline maps information future monitoring. highlight need effective management strategy network effectively protect local biodiversity, should include measures species, mitigating fragmentation, soil degradation, as well adaptation eco-enhancing strategies multiple agriculture.
