Implementation details

The question relates to several criteria from ESE1. Sensitivity for example is very important in this case, with the goal of identifying priority areas for preservation/restoration of reef-forming species, as it is the degree to which a species is influenced by one or more aspects of climate (Dawson et al., 2011) or anthropogenic stressors, with sensitivity directly related to the species’ inner traits and is used in Vulnerability assessments. Other criteria in the Vulnerability and Stability macro-criteria of the ESE1 can be relevant for the answering of this question such as: Traits-based Adaptivity, Resilience/Recovery, Resistance, Species Vulnerability to Climatic and Anthropogenic stressors, Ecosystem Integrity, General Adaptivity and Stability.

Critical life cycle areas macro-criteria includes connectivity related criteria such as larval source and recruitment areas (larval sink areas), which is an important element to be taken into account when seeking to preserve/restore mussels. Abundance hotspots of a functionally important species such as Lanice conchilega strongly relates to the defined criteria of Presence of key functional species and key functional areas (e.g. larval source areas).

The second criteria type, not directly depending on the ecological part, is the feasibility of the protection depending on the intensity and importance of human activities and the possibility to agree to a trade-off decision and ensure monitoring and compliance (cf. ESE3).

For restoration purpose, several guidelines exist that synthetize the best known practices at least for mussels. Performing a review of this guidance to select the most relevant methods regarding local conditions and the development of a dedicated monitoring in the chosen area is highly recommended.

For the steps to be undertaken D3.3, tacking climate change dimension, provides some interesting insights. The core analysis is a sensitivity-based vulnerability assessment and the definition of a portfolio of scenarios. To support the process, for benthic species, a census list of traits of importance, with an already filled matrix for British Isles and the main species of interest including Lanice conchilega and different mussel species, can be found in the Biological Traits Information Catalogue (BIOTIC) (Marine Life Information Network. Plymouth: Marine Biological Association of the United Kingdom, 2006).

Cumulative Effects Assessment (CEA) and area prioritization and optimization analyses can also be applied. CEA offers critical insights into the spatial and temporal distribution of human-induced impacts under both current and future scenarios. This information is essential for identifying areas that are either currently experiencing high pressure or are projected to be heavily impacted, informing planning and management strategies.

When combined with CEA, area prioritization analysis can help guide the selection of zones for conservation in a way that minimizes potential conflicts between the expansion of MPAs and existing human activities. This integrated approach ensures that conservation efforts are both ecologically effective and socioeconomically coherent. Tools for addressing both types of analyses have been provided in D3.4 (ESE1).
