2 COM (2011) 244 Our life insurance, our natural capital: an EU biodiversity strategy to 2020 Aiming at: reversing biodiversity loss and speeding up the EU's transition towards a resource efficient and green economy. It is an integral part of the Europe 2020 Strategy, and in particular the resource efficient Europe flagship initiative.

Protect species and habitats Maintain and restore ecosystems EU Biodiversity Strategy Target 3 Increase contribution of agriculture and forestry to maintaining and enhancing biodiversity Target 6 Step-up action to tackle the global biodiversity crisis 2020 Targets Target 5 Combat invasive alien species Target 4 Ensure the sustainable use of fisheries resources

6 How to map ecosystems from COS 07 (N5)? Geological map to separate pine forests of high natural value from other pine plantations; Distance to coast line to separate coastal cliffs and dunes ecosystems from inner cliffs and sparsely vegetated areas; NDWI derived from satellite imagery to separate dry grasslands from wet grasslands; Vegetation series map to separate different types of native heathland, scrub and woodland. Ecosystems Mapping 1 (COS N5) : 1 (EUNIS) relations between land use types and EUNIS habitat types 1 (COS N5) : N (EUNIS) relations solved using auxiliary information: 1: N auxiliary information (25%) 1:1 direct relationship (75%)

12 Conclusions - Alentejo Ecosystem types tend to be specialized in the services they provide, however: dry and sparsely wooded grasslands (montado) combine soil protection and animal production; coniferous woodland combines carbon sequestration and fiber production. There is a significant mismatch between condition and ecosystem services: e.g., shrublands and broadleaved deciduous woodland tend to have high ecological condition but low provision of ecosystem services;

13 Conclusions - Outlook First mapping and assessment of ecosystem services in the EU based on the European Commission s MAES guidelines: mapping ecosystems using the EUNIS classification and analyzing conditions and services based on it. The fine grained (1 ha) analysis here developed can provide the basis for spatialized natural capital management policies (e.g., identification degraded areas for recovery, green infrastructure, payments for ecosystem services in the CAP). Future work involves the extension to all of Portugal, the increased use of process based models and the consideration of a wider range of ecosystem services and indicators of ecological condition.
