ABSTRACT
This study focuses on producing detailed cartography by converting Portugal’s national land-use and land-cover (LULC) data into the European Nature Information System (EUNIS) habitat classification. The resulting cartography streamlined the original 83 Portuguese LULC classes to 79 EUNIS habitat categories, reflecting shifts in class representation. Artificial and agricultural territories have reduced detail, while forests and shrublands gained classes represented by ecologically specific detailing. The resulting cartography prioritises natural and semi-natural habitats, enhancing its utility for biodiversity assessment and land management.
The methodology developed to address the challenge of non-direct correspondences between the LULC and EUNIS systems. By integrating additional ecological data, the framework is adapted to various geographic contexts.
This approach supports landscape transformation planning, facilitating the integration of green infrastructure and promoting resilience and ecological connectivity. Furthermore, the standardised classification enhances the mapping and management of ecosystem services at multiple scales.
