Restoration of deep-sea habitats
to rebuild European Seas

REDRESS aims to provide a key contribution to the EU commitments towards restoring degraded deep-sea ecosystems. REDRESS will provide solutions to prioritize future restoration actions, extend deep-sea restoration to previously neglected habitat types, and demonstrate the feasibility, potential, and value for success of deep-sea ecosystem restoration. The project will focus on habitats that have great potential to contribute to carbon sequestration and climate mitigation but have been degraded by deep-sea fishing, especially trawling. Specifically, REDRESS will study vulnerable marine ecosystems, including sea pens and bamboo corals on soft sediments, coral gardens, cold-water coral reefs, sponge fields, and cold seeps. REDRESS will map degraded deep-sea habitats and identify habitat refugia to prioritize restoration efforts that will adapt to future scenarios of climate change. To adopt and adapt cutting-edge solutions for both restoration interventions and monitoring. REDRESS will offer nature-based solutions to public authorities and operators to advance ecosystem restoration in the deep sea following the EU’s marine restoration strategy. Finally, REDRESS will provide novel insights into the advantages and limits of active vs passive deep-sea restoration, and related cost-benefit analysis of restoration in different deep-sea habitats supporting policies and decision makers.

Specifically, REDRESS will address the following interconnected actions:

In the hidden depths of the ocean, vital deep-sea habitats crucial for carbon sequestration are degraded or under threat. REDRESS will demonstrate the feasibility, sustainability, and value of deep-sea ecosystem restoration and provide public authorities with solutions to plan and upscale restoration operations. REDRESS will provide a new vision of ecosystem restoration in European deep seas and contribute to a roadmap for the European Green Deal.

The ambition of REDRESS is to:

  • identify priority areas for deep-sea restoration to support future EU policies and investments (i.e., Biodiversity Strategy 2030 and European Mission “Restore our ocean and waters by 2030”);
  • allow the replicability of the upscaling of marine restoration across the EU and beyond;
  • demonstrate the technological readiness for the upscaling of deep-sea ecosystem restoration;
  • implement low-cost monitoring systems to assess the success of deep-sea ecosystem restoration;
  • provide the tools needed to empower society and governance to support sustainable and effective marine restoration activities in the mid- and long-term.


REDRESS will identify the drivers of deep-sea habitats’ degradation and biodiversity decline by collecting new and existing data and will prioritize deep-sea habitats needing restoration considering current and future climate scenarios. REDRESS will apply proven ecologically and economically cost-effective protocols for the restoration of threatened and damaged deep-sea ecosystems in upscaling restoration actions at European level.

REDRESS contributes to:

  • reverse biodiversity decline of key deep-sea habitats through several restoration interventions in EU seas;
  • provide robust protocols for the restoration of deep-sea habitats, including VME;
  • improve the health status of both species and habitats, from cold-water corals to coral gardens, and to soft-bottom sea pens and bamboo corals, and cold seeps;
  • highlight areas relevant to the design of effective MPA networks and climate refugia.


REDRESS will adopt and integrate guidelines, protocols, indicators, and available tools to demonstrate the feasibility of upscaling restoration in the deep sea, its cost-effectiveness, scalability, and replicability. REDRESS will combine new technologies for on-site restoration and temporal and spatial monitoring of restoration actions, using new autonomous devices. REDRESS will apply a multi-technological monitoring approach to assess the effects of restoration on different attributes of the species/habitat target.

REDRESS can count on:

  • the application of the most advanced technologies to develop nature-based solutions to restore deep-sea habitats;
  • the development of new technologies to expand deep-sea restoration at large spatial scales;
  • the use of cutting-edge technologies to monitor the success of restoration interventions in different deep-sea habitats;
  • the application of common low-cost solutions to assess the effect of restoration on key variables to monitor: a) Biodiversity; b) Health of restored habitats and c) Connectivity.


REDRESS results will adopt innovative solutions for monitoring restoration efficiency, its benefits, and trade-offs with a potentially important impact on the European job market. REDRESS will promote a better awareness amongst society (at all levels) of the potential and value of marine restoration to contribute to provision of healthy seas for all. REDRESS will support the EU Commission in defining guidelines for restoring deep-sea ecosystems, biodiversity, and ecosystem services in European seas and oceans.

REDRESS aims to:

  • assess the cost-benefit of the restoration of different deep-sea habitat types and the risks related to climate change scenarios and multiple stressors.
  • assess the potential economic impact of deep-sea restoration at EU level and set a framework for funding restoration interventions.
  • provide a robust contribution to decision-making and policy formulation, particularly to EU initiatives, such as the restoration law, fisheries, and offshore infrastructure policy.
  • engage society, practitioners and (end)users in deep-sea habitats restoration and fill the gap in assessing the values of deep-sea biodiversity recovery.
