1 University of Cagliari XXIX Cicle PhD Course in Earth and Environmental Sciences and Technologies The endemic vascular flora of Sardinia: analyses, distribution patterns, ecological processes and implications for conservation Mauro Fois Tutor: Prof. Gianluigi Bacchetta Co-Tutor: Doc. Giuseppe Fenu PhD Annual Report Department of Chemical and Geological Sciences Cagliari, 13 January 2016

2 Summary First-year research and general perspectives 1. Geodatabase of endemic plant species 2. Perspectives 3. First results obtained (Biogeography of Sardinia) Second-year researches and results 1. The effectiveness of the conservation measures implemented up to now 2. The study of main drivers which determine the current distribution pattern 3. Concepts and methods in spatial conservation prioritization 4. Collaboration with other projects Purposes for the third year

3 First-year research Geodatabase of endemic plant species Literature and Herbarium specimens: about 7000 records (11%) (Moris, 1870) (Valsecchi et al., 1977) + Arrigoni & Bocchieri(1995) Unpublished data : about records (89%) (Bacchetta, 2006) (CAG, CAT, FI, SASSA, SS, TO) Seed collection data Personal communications of CCB staff members Field excursions Continue validation and taxonomical and distributive updating

4 First-year research Perspectives data occurrences

5 First-year research Perspectives data occurrences

6 data occurrences? Cartography is used for the purposes of drawing a plan First-year research Perspectives e.g. Travels Wars

7 First-year research Perspectives data occurrences? Cartography for conservation planning

8 First-year research Perspectives CONSERVATION PLANNING...a long and winding road 1. Know the territory 2. Know what we havealreadydone and what we could do in thefuture 3. Know which factors determine the distribution of the endemic plant species 4. Know how much and where we should protect 5. Find an effective method for the consevation planning

9 First-year research Results The biogeography of Sardinia (know the territory) Sectors

10 Second-year research Researches and Results The Aichi Biodiversity Target 12 at regional level: an achievable goal? (Know what we have already done )

11 The Aichi Biodiversity Target 12 at regional level: an achievable goal? ( and what we could do in the future) Area Under the Target (AUT) = A -a Protected species all endangered species A = 0, years

12 The Aichi Biodiversity Target 12 at regional level: an achievable goal? ( and what we could do in the future) Area Under the Target (AUT) = A -a Protected species all species years

13 The Aichi Biodiversity Target 12 at regional level: an achievable goal? ( and what we could do in the future) Area Under the Target (AUT) = A -a Protected species all species a = 0, years

14 The Aichi Biodiversity Target 12 at regional level: an achievable goal? ( and what we could do in the future) Area Under the Target (AUT) = A -a Protected species all species AUT = A -a years

15 The Aichi Biodiversity Target 12 at regional level: an achievable goal? ( and what we could do in the future)

26 Second-year research Collaborations 1. Petites Îles de Méditerranée(PIM) initiative Cartography and checklist of endemic flora RESULTS(expected/obtained) One paper on Sardinian satellite islets flora (under review) Atlas of Mediterranenan small islands (Italian/English) 2. GREATmed European Project 3. Pilot project of Gentiana lutea L. Vulnerability assessment (endemic plant species) Field surveys and ecological analyses RESULTS(expected/obtained) One poster (IAVS, 2015) Two peer-reviewed papers (in progress) RESULTS(expected/obtained) One prsentation (GCB, 2015) One poster (ECCB, 2015) One peer-reviewed paper (pubblished, J Nat Cons) Two peer-reviewed papers (in progress)
