Site description

Focus of study

The topic studied was the ecosystem services provided by kelp forest habitats. The management of Laminaria hyperborea exploitation, the most abundant kelp species, has been implemented and negotiated 15 years ago by kelp harvesters. In a context of increasing demand for kelps, the main objective, through the ecosystem services assessment approach, was to provide new insights to the current management debate, and for the search of new trade-offs. The aim is to achieve precise management of the kelp field that allows a sustainable yield and employment for fishermen, while protecting patrimonial species as Bottle-nose dolphin and mitigating impacts on other uses.

Key stakeholders and their involvement

A dedicated commission of the Regional Fisheries Committee (CRPMEM) is in charge of defining proposals for kelp harvesting management rules, which are then amended and codified by the State representative.

Having some short-term objectives specified in the 2014-9271 regional regulation facilitated kelp harvesters’ involvement in many key steps of the ecosystem services assessment. Moreover, the Park’s council includes a wide range of local stakeholders. Through their debates, the team broadly analyzed the social demand of kelp ecosystem services and refined the kelp social-ecosystem representation.

Approach for Ecosystem Services Assessment

The triage of kelp ecosystem services was managed in order to reduce the scope of the assessment. Considering the numerous factors of influence which must be taken into account, the team chose to develop a dynamic model of the kelp social-ecosystem for simulating the impacts of various fisheries management options on 4 or 5 key ecosystem services.

The building of this model on a participative approach was the opportunity to identify available data and to make a precise assessment of gaps in data and knowledge. The model has sensitive metrics to drivers of change and provides indictors for the multi-criteria analysis of the scenarios impacts on ecosystem services.
