Can facilitation processes enhance effectiveness of restoration actions in the coralligenous habitat?
Coralligenous outcrops are slow-dynamic habitats exhibiting high structural complexity. If these valuable habitats are degraded, relatively long time is required to recover their structure and full functionality. In order to reduce recovery times, restoration actions can focus on target habitat-forming species. Facilitation processes (i.e. positive species interactions), rarely considered to date, may be further explored to enhance the effectiveness of coralligenous restoration initiatives. Here we test if erect habitat- forming species, putatively modifying light penetration and/or water movement, can affect the survival and growth of co-occurring encrusting and massive ones. For that purpose, we designed an experiment using the red gorgonian Paramuricea clavata and bryozoans, important coralligenous structural animals, as model organisms. The experiment, replicated in Spain, Italy and Croatia, is based on the comparison between series of 0.25 m2 experimental plots. Experimental treatments include addition of bryozoan recruitment- enhancing devices (plastic grids) with and without gorgonian colonies and controls (empty and artefact ones) for a total of 4 replicates per treatment. The hypothesis is that the erect layer (15 P. clavata fragments up to 20 cm in maximal height per experimental plot) could facilitate the settlement of bryozoan colonies onto grids within the experimental plots and enhance their survival and growth. The experiment was initiated in May-July 2017 within the EU Horizon 2020 project MERCES (Marine Ecosystem Restoration in Changing European Seas, http://www.merces-project.eu/) and it is still ongoing. In this contribution we present and discuss our preliminary experimental findings.
