Abstract/Summary

Aim Gorgonian forests are among the most complex of subtidal habitats in the Mediterranean Sea, supporting high biodiversity and providing diverse ecosystem services. Despite their iconic status, the geographical distribution and condition of gorgonian species is poorly known. Using multiple online data sources, our primary aims were to compile, map and analyse observations of gorgonian forests in Italian coastal waters to assess the biological complexity of gorgonian forests, evaluate impacts and vulnerable species, and identify areas of special interest inside and outside of marine protected areas (MPAs) to help prioritize conservation strategies and actions. Location Italy. Mediterranean Sea. Methods Using a multi-source data integration approach, we collected and integrated data from scientific publications, the World Wide Web including social media platforms, citizen science projects and SCUBA diver questionnaires into a unified spatial framework. This method provided up-to-date information on the geographical distribution, abundance, and health of major habitat-forming gorgonian species in Italian coastal waters. Results Higher abundance and complexity of gorgonian species occurred outside MPAs. Areas of Special Interest (n = 167) were identified (80 inside and 87 outside MPAs). Three locations supported all seven focal species: Capo Caccia MPA, Portofino MPA and Catania (unprotected). The purple gorgonian (Paramuricea clavata), the most abundant and geographically widespread species with highest forest complexity, was affected by multiple stressors including thermal stress, disease and fishing. Main conclusions The multi-source approach was a rapid and cost-effective tool to gather, analyse and map disparate data on gorgonian forests spanning 27 years of underwater observations both inside and outside of MPAs. The unique perspective given by this approach demonstrates the suboptimal protection of several habitat-forming gorgonian species. The approach has great potential for wider application and offers a more inclusive participatory model for crowdsourcing and repurposing under-utilized observations while also increasing ocean literacy.
