Based on the list provided by UNEP-RAC/SPA (2011) and field data from 20 coralligenous sites along the Eastern part of the Adriatic Sea, a preliminary selection of typical/indicator species that should be monitored within the Croatian national protocol has been proposed. This list includes 37 species/categories: 2 algal builders, 13 animal builders, 2 agglomerative animals, 5 bioeroders, 13 species of particular importance and 2 invasive species/categories. To verify the existing list or to propose a more complete one, additional field research is needed, especially in the understudied southern part of the Croatian coast.
