Conservation of native plant species from Sardinia (Italy)
Plant conservation of the native species from Sardinia through seed banking and research supporting their ex situ and in situ conservation

Sardinia is the second largest island in the Mediterranean Sea (after Sicily), occupying an area of 24,090 square km and comprising a flora of 2,407 species. The isolation and the high geological diversity in this island have created a wide range of habitats with high level of endemism (347 plant species), especially on the Gennargentu, Supramonte and Sulcis-Iglesiente Mountains.
At the beginning of September 2006 a Memorandum of Collaboration was signed between the Royal Botanic Gardens, Kew and the Centre for Conservation of Biodiversity (CCB), in the Department of Botany (now included in the Department of Life and Environmental Sciences) at the University of Cagliari aiming to contribute to the plant conservation of the island.
The collaboration encompasses seed collecting, conservation, training and research on seed biology and germination ecophysiology and plant demography of Sardinian native plant species.
All targeted species are representative of the Mediterranean flora and are prioritized according to their conservation importance and phytogeographical interest.
The project has contributed so far around 100 species to the Millennium Seed Bank targets and eight publications, including a conservation assessment on Lamyropsis microcephala, to the MSB research target. It is planned to continue with the ex situ conservation programme and to expand the research into germination ecophysiology and plant demography of Sardinian native plant species.
