For this project we elaborated a reference situation for the natural values of the Integrated Territorial Intervention of Natura Network Areas of Alentejo (ITI ZRNA), foreseen in Local Strategic Plans, taking into account management priorities and associated supports.

Natura 2000 is a network of core breeding and resting sites for rare and threatened species, and some rare natural habitat types which are protected in their own right. It stretches across all 28 EU countries, both on land and at sea. The aim of the network is to ensure the long-term survival of Europe's most valuable and threatened species and habitats, listed under both the Birds Directive and the Habitats Directive.

The study area covers eight classified sites totaling 371,276.8 hectares.
The objective of this work was to produce the cartography of habitats of these Natura 2000 sites and the characterization of the main threats to their conservation:

1. Identification of basic cartographic elements and construction of a GIS;
2. Determination of the Minimum Sampling Unit and Validation Criteria;
3. Collection of additional mapping support elements;
4. Identification of Habitats supported in the base mapping and additional elements;
5. Confirmation and validation of Habitats mapping.
