Abstract: Protected areas (PAs) are the main global policy instrument to avert the current biodiversity crisis by conserving important species and habitats on site. Yet important pressures around PAs and in PAs, notably land use-land cover (LULC) changes, jeopardise the conservation role of these tools. In Spain, as well as in most developed countries, land development is the main pressure on its rich biodiversity. Here, we used a semi-experimental Before-After-Control-Impact (BACI) research design with covariates to ascertain whether three categories of multiple-use PAs including Nature Parks, Sites of Community Importance (SCIs) and Special Protection Areas (SPAs) have been effective to prevent land development in Atlantic Spain between 1987 and 2017 using CORINE Land Cover (CLC) data. We split our census sample of PAs according to two geographic zones: coastal zone and inland zone, and four administrative sub-zones (regions with distinctive governance systems): Galicia, Asturias, Cantabria and the Basque Country. We created and tested the validity of three types of controls specific to each PA category: standard 5-km buffer controls, bio-physically adjusted standard controls, and bio-physically adjusted random controls across zones. Multiple-use PAs reduced, though not completely avoided, land development in all zones and sub-zones compared with controls. An effectiveness gradient among PA categories was apparent: NPs ≥ SCIs > SPAs. Coastal areas, both protected and unprotected, experienced greater land development rates than inland areas, with coastal SPAs showing poor effectiveness results. The Basque Country was the best-performing region regarding PA effectiveness, with the remaining regions showing similar PA performance results regardless of the prevailing political party in power for most of the study period. Random controls had the greatest bio-physical similarity to their cases and produced larger control areas than standard buffer controls. The limited effectiveness of multiple-use PAs, especially of SPAs, at preventing land development in highly pressured coastal areas suggests the need for enhanced legal protection of these areas if long-term biodiversity conservation is to be ensured. Governance and political factors are likely to have influenced the effectiveness of PAs in Spain and should thus be further considered in environmental studies.
