Protecting the Baltic Sea: Uncovering gaps in MPA management

CCB • March 6, 2025

The Baltic Sea, one of the world’s largest bodies of brackish water, is home to a wealth of varied biodiversity. But this unique and delicate ecosystem is facing increasing pressures from human activities and global threats, such as climate change. A key strategy for safeguarding the sea is the establishment of Marine Protected Areas (MPAs)—designated zones where human activities should be regulated for the benefit of biodiversity, allowing ecosystems to recover and thrive.


Despite globally recognized efforts by the countries bordering the Baltic Sea to designate MPAs, significant gaps remain in their governance, management, and monitoring—both individually and as part of a transboundary network. To address these gaps, the PROTECT BALTIC project—under the umbrella of the regional sea convention HELCOM—is working to better understand the current state of the Baltic Sea MPA network and its management across the region, as well as how countries can collaborate to enhance it. A key step in this process is updating and improving the region’s MPA Portal, a regional platform designed to store comprehensive MPA information and strengthen the capacity of marine protection actors. 


In this process, the project is uncovering some notable challenges, but also some significant opportunities.


Estefania Cortez, PROTECT BALTIC Project Manager / Legal expert from CCB, is leading the task of collecting and compiling information from the Baltic countries’ MPA management plans and other similar official instruments. She provides insights into the complexities of MPA management in the region and the crucial role that the project is playing in modernizing information and bridging existing gaps.

A shared commitment to protecting the Baltic Sea

PROTECT BALTIC is a collaborative effort aimed at strengthening the designation, management, governance and effectiveness of MPAs across the Baltic Sea, with the goal of ensuring quality protection for marine life. Estefania explains, “Initially, our aim was to consolidate and analyze data on nationally recognized MPAs in the Baltic region. But as the project progressed, we realized that the landscape for management of these areas was far more complex than anticipated. Our role evolved from mere data collection to actively verifying and cross-checking information to ensure consistency and accuracy.”


The project aims to address the core challenge of fragmented and inconsistent management-related data across different countries, while also reducing barriers to accessing this information. Each nation has its own way of defining, managing, and documenting these areas and there is currently no regional platform where such information can be shared. As Estefania highlights, “While countries bordering the Baltic Sea have made significant strides in establishing MPAs, there remains a lack of a common, unified framework. Each country has its own regulations and management frameworks in place. Some areas, for example, are privately protected, while others are part of large national programs and key strategies. These variations make it difficult to assess and objectively compare how MPAs are being managed across the region as a whole."


The work done so far in PROTECT BALTIC has already led to some groundbreaking results: through our data collection efforts, the number of MPAs documented in the region has increased tenfold. Initially, only 189 MPAs were included in the database, but with new submissions, this number has surged to an astounding 1,876 MPAs. Estefania explains, “A large part of the increase in data is a direct consequence of recent national efforts to continue designating MPAs while strengthening effective measures in those areas.”

Collating MPA management data to build a comprehensive picture

The core of this work involves compiling and updating information from MPA management plans—comprehensive documents that outline protection objectives, strategies, and actions for managing each MPA. These typically include details on protection goals, the pressures faced by the area, the specific measures in place to address these challenges, monitoring protocols, and enforcement actions. They are essential for understanding how each MPA is designed to protect marine ecosystems and ensure sustainable use. 


Estefania explains, “Initially, the estimate for the number of available management plans ranged somewhere between 100 and 200. But it turned out there were far more than we anticipated—over 850 plans or similar documents across the region. This required us to rethink our approach and bring in additional support to extract key data from these documents.”

The task was complex, involving tracking down the documentation, analyzing the plans, and collecting and collating data. Since most plans are also only available in the national language of the country where the MPA is located, all the collected information also needed to be translated into English as part of the process. With each nation defining and managing MPAs differently, some lacked clear legal frameworks or official documentation, making data interpretation challenging. To address this, the team developed a structured methodology for extracting the data, which was continually tested and refined as specific documents required additional guidance.


A group of nine trainees, with expertise in environmental and data management and fluency in at least one of the Baltic Sea languages, was onboarded. Each trainee focused on a specific Baltic country, except for Sweden, where three trainees were needed to handle the high volume of management plans. Estefania notes, “We quickly realized that translating every single document in its entirety would be too costly and time-consuming, so we trained the team to extract relevant information in their local languages and condense it into a standardized Excel format. We further utilized pre-determined internationally agreed lists on species and habitats, as well as information on human activities and pressures produced within the project.”


Harmonizing the data was yet another challenge, as countries defined threats, management measures, and conservation goals in unique ways, sometimes also between areas or area types within the same country. Despite the varied levels of detail in the plans, the team remained flexible and methodical in extracting relevant information.


What has been collected?


The key categories of information collected include:

  • Basic MPA details: name, code, designation year, type, management plan status, IUCN category, stakeholder engagement, and transboundary elements.
  • Protected features: species, habitats, ecological functions as well as cultural heritage and ecosystem services, whenever possible.
  • Human activities and pressures: including shipping, fishing, tourism, and pollution, utilizing the Marine Strategy Framework Directive (MSFD) and Water Framework Directive (WFD) as references.
  • Protection measures: ranging across the whole span of human activities and from seasonal restrictions to full no-take zones.
  • Monitoring efforts: identifying the direct inclusion of ecological or human activities monitoring in the area. The data has been gathered from official national MPA lists, government institutions, legal sources, and ongoing conservation projects such as Biodiversea in Finland. 

Challenges, lessons learned and country profiles

Although the large volume of collected data still requires further processing, and national consultation and review before detailed conclusions can be drawn, one of the key takeaways from this work has been the significant diversity in how MPAs are designated and managed across the Baltic region. Some countries, like Germany and Finland, have multiple jurisdictions responsible for MPA oversight, leading to variations in management plans within the same country. 


A major issue uncovered is the lack of marine-specific protection measures in many MPAs. This raises concerns about the effectiveness of existing protections and highlights the need for adaptive management strategies that allow for the modification or expansion of protection measures as knowledge improves and the dynamics affecting the ecosystem change.


Another significant challenge has been gaps in data comprehensiveness and the availability and accessibility of data. Many management plans either lack critical information or exist only in non-digital formats, complicating data gathering and analysis. Additionally, some countries experienced delays in providing up-to-date documents, either because the information wasn’t available digitally or because the plans were still under revision.


“The data gaps became very clear after we received the first round of information from the countries,” Estefania Cortez explains. “Some management plans were missing or incomplete, and in some cases, MPAs themselves were not listed correctly. This is a problem because, without accurate data, we can’t measure the effectiveness of protection efforts or understand where and what additional measures are needed.”


While the team has gathered substantial amounts of data—far more than initially expected—Estefania notes, “We have gathered enough data to highlight key trends and challenges, but protection planning requires a comprehensive understanding that goes beyond just data points. This includes broader ecological, economic, and social contexts, which are being actively addressed under other work packages within PROTECT BALTIC.” 


To make the management data as useful as possible, it’s crucial to consider both what has been collected and how it is applied. In some cases, there are challenges with data-sharing between countries or institutions, which can result in incomplete or outdated information being available. Moving forward, refining the datasets to ensure they are comprehensive and applicable will be essential.

The data collection showcased the different approaches each country has adopted:

  • Denmark: The team reviewed 85 management plans covering different types of MPAs, including Natura 2000 sites and other protected areas. However, 51 MPAs have been recently added and are currently being reviewed.
  • Estonia: 38 management plans were reviewed, but many MPAs have overlapping areas with multiple protected area categories, adding an important factor into the assessment process.
  • Finland: The most complex case, with over 1,000 MPAs (including Private Protected Areas). Often these sites fall under multi-management plans, meaning that a single document can cover multiple MPAs.
  • Germany: 82 management plans were reviewed. The country’s approach to MPA management is highly jurisdictional, with different rules applying to MPAs depending on the federal and state governance levels.
  • Lithuania: Only 7 management plans or similar documents were assessed, as most MPAs fall under larger territorial conservation programmes rather than standalone sites.
  • Poland: The team analyzed 22 management plans, which highlight the varied pressures affecting MPAs, from industrial development to tourism.
  • Sweden: With 148 management plans reviewed so far, and 292 still being checked, the trainees are exploring the use of AI to assist and speed up the data extraction process, especially for identifying protected species and habitats within a specific MPA.


An important decision was made regarding Latvia and Åland. Both Latvia and Åland are separately undergoing full-scale revisions of their suite of management plans, with updates expected to be finalized only in the second half of 2025. 


“If we included their current management plans in our dataset at this stage, they’d be outdated before they could even be added to the database,” Estefania explains. “So, we decided to wait until their new plans are finalized to ensure we use the most accurate and relevant information. In the meantime, we stay in constant communication with the relevant authorities to track the progress of their updates.”

Filling in the blanks

A central aspect of the work has been gathering data on the pressures faced by MPAs, such as overfishing, pollution, and climate change, as well as the mitigation measures being implemented, like fishing restrictions and habitat restoration. While some of this data has been useful, Estefania points out that certain gaps remain: “We are still completing the overarching MPA landscape. There is a lack of data regarding the intensity and location of the pressures. We need more detailed information on how these pressures are affecting specific areas and how effective the mitigation measures have been.”


To address this, PROTECT BALTIC is currently working on advancing the spatial modelling of human activities and the resulting pressures, including identifying what pressures are suited for management at MPA level. 


Another significant gap is the limited data collected on MPA monitoring, which is essential for assessing whether management measures are being followed. Estefania explains, “Some countries focus on compliance, while others prioritize ecological tracking. We need to ensure that monitoring systems are standardized, cover both ecology and human activities, and are regularly updated. Opportunely, this in-depth research will be further explored by the Monitoring work package within the project.”


The way forward: a unified approach

Looking ahead, PROTECT BALTIC is preparing to analyze the second round of data collection, which was open until February 2025. This round has focused on addressing gaps and refining the initial findings, filling in missing details, cross-checking discrepancies, and ensuring that the dataset is as robust as possible. While the first data call primarily identified MPAs, this phase focuses on understanding how they are managed and protected through specific sectorial measures. The last step in the process will be populating the Baltic Sea MPA database and inviting the countries to review and quality check the data before it is made publicly available.


Estefania emphasizes, “The success of the project depends on collaboration with all Baltic Sea countries. We need their active involvement to validate the data we’ve collected, and we also need their feedback throughout the project to improve the MPA Portal. The more data we can collect, the better we will understand the challenges facing the Baltic Sea, and the better we can recommend suitable solutions to protect these areas.”


This second phase will also gather additional information about national legal frameworks, sectoral instruments, and other factors influencing MPA management. The insights gained will be instrumental in shaping future conservation strategies and recommendations, ensuring that the work translates into tangible policy and conservation actions that protect biodiversity.

Brussels, 4 November 2026: Environmental NGOs welcome the European Commission’s decision to not include a revision of the Common Fisheries Policy (CFP) in its 2027 Workplan, announced today, and call on the Commission to maintain this course. To improve ocean health and biodiversity, BirdLife, BLOOM, Coalition Clean Baltic, ClientEarth, Environmental Justice Foundation, Oceana, and Seas At Risk urge the Commission to prioritise full implementation and enforcement of the existing CFP to rebuild fish populations, protect marine ecosystems, and secure a sustainable future for fishers and coastal communities. “The Commission has rightly chosen to follow the findings of its own CFP evaluation , published in April this year, and to focus on holding Member States accountable for implementing the law”, said the NGOs. “Reopening a policy that has not yet reached its full potential would halt timely implementation, waste valuable time and delay the meaningful action that European fishers and marine ecosystems urgently need.” A competitive and resilient fisheries sector can only be built on: healthy fish populations; a system that gives a fair share of space and resources to fishers that have a low impact on the marine ecosystem; and a fleet that is enabled to make a just transition to lower environmental impact, reducing dependence on subsidised fossil fuels, and responding properly to the climate crisis. The CFP outlines a precautionary pathway forward, centering fisheries management on scientific advice and ecosystem protection, minimising the impact of fishing on the marine environment while aiming to provide a sustainably sourced food source for people throughout Europe. “The European Commission must now demonstrate its political ambition by delivering on the CFP, which will allow fish populations to recover, will help achieve food security, along with the wellbeing of European fishers and coastal communities, and protect ocean health”, said the NGOs. “With imminent annual fisheries negotiations between the Commission, Member States and third countries, including the UK and Norway, this will be a key opportunity to finally close a major CFP implementation gap by setting fishing limits that are geared towards rebuilding struggling fish populations and fisheries.” The environmental NGOs call on member states to cooperate with the European Commission on stronger implementation measures to fulfil the objectives of the CFP, and put European citizens and environment at the heart of their position going forward.

27 October 2026 , Luxembourg - EU fisheries ministers increased central Baltic and Bothnian herring catch limits beyond the European Commission’s proposals and significantly increased the sprat catch limit, falling short of the precaution needed to protect the role of herring and sprat in the Baltic Sea food web. The Council also rejected proposed cuts to accidental catches of severely depleted cod and western Baltic herring populations. NGOs warn that fishing limits remain too high and urge EU ministers to follow the agreement with concrete plans to rebuild depleted fish populations. Herring: further measures needed to safeguard fragile recovery and protect vulnerable populations EU fisheries ministers increased the catch limit for central Baltic herring to 165 228 tonnes, a 71% increase compared with 2026. The population has shown signs of improvement after years of depletion. However, the central Baltic herring population remains vulnerable, and rebuilding must restore healthy age and size structures as well as overall abundance. Although below the scientific headline catch advice, the Council’s decision exceeds the Commission’s proposal, which was more precautionary and recovery-oriented and should have been followed by the ministers. “Ministers have recognised the need for caution, but still allowed more herring to be caught than the Commission proposed. These vulnerable populations need a stronger chance of lasting recovery, with clear rebuilding targets, a timetable for reaching them and measures that are implemented and enforced ,” said Cathrine Pedersen Schirmer, Senior Fisheries Policy Advisor at Coalition Clean Baltic. For Bothnian herring , ministers retained the three-month spawning closure but increased the Total Allowable Catch (TAC) by 12% , despite the population remaining below healthy levels. The Commission’s proposed TAC for this fish population was already a compromise between population rebuilding and maintaining fishing opportunities. The agreed higher TAC poses a risk to the recovery of the Bothnian herring population and creates increasing uncertainty for the industry. “ Fisheries decisions must also account for the risks to fish population recovery. Even catch limits within the ICES advice range can leave stocks at risk of remaining below the biomass levels that should trigger recovery measures. Fishing opportunities must give depleted populations a real chance to recover to healthy level s,” said Beatrice Rindevall, Chairperson of the Swedish Society for Nature Conservation. The Gulf of Riga herring TAC was also set above NGOs’ recommendations, with an increase of 11% compared with 2026, despite the recent decline in its spawning biomass and its importance to the Baltic food web. Lower limits for this fish population would have better supported population health and long-term resilience. Sprat: recovery must extend to the Baltic Sea food web The sprat agreement remains a significant concern. The Council’s decision, in line with the Commission’s proposal, to increase the sprat catch limit by 44% to 291 590 tonnes exceeds the level NGOs recommended. Although the population has increased, the agreed limit does not sufficiently account for sprat’s importance as prey for cod, salmon, seabirds and other marine wildlife, persistent catch misreporting or the risk of catching vulnerable herring alongside sprat. “ Herring and sprat are vital to the Baltic Sea ecosystem. When setting fishing opportunities, decision makers must leave enough prey in the water to support predators like cod and salmon, to rebuild ecosystem health and align with the EU’s nature restoration ambitions ,” said Justyna Zajchowska, Fisheries Lead for WWF Baltic Sea Programme. Salmon: no increase in catch limits, but stronger protection needed NGOs welcome the decision not to increase salmon fishing opportunities. However, fishing should be restricted to compensatory hatchery-released salmon or salmon from rivers where populations are at full reproductive capacity. Fishing on vulnerable wild populations must be avoided and, if returning salmon numbers are insufficient, additional adaptive management measures should be deployed immediately, considering the impact of recent poor spawning runs. “ Good returns to some large rivers are encouraging, but they do not demonstrate recovery across the Baltic region. Many smaller river populations remain in serious difficulty. We need fishing restrictions that protect those vulnerable salmon throughout their migration and allow enough fish to reach their spawning grounds ,” said Thomas Johansson, Chairman of Östersjölaxälvar i Samverkan and Secretary General of the Baltic Salmon Fund. Cod, western Baltic herring and plaice: Council misses opportunity to curb bycatch Both Baltic cod populations and western Baltic herring remain severely depleted. Targeted cod fisheries remain closed, while ministers retained the small-scale fisheries exemption for western Baltic herring. Yet ministers agreed bycatch quotas well above the Commission’s proposals for 2027 and at the same level as 2026, falling short of the protection sought by NGOs. For all three populations, the agreed bycatch quotas permit continued catches despite ICES advice for zero catch. The Council’s decision to increase the plaice TAC to 11,237 tonnes , well above the level NGOs recommended, missed an opportunity to secure a reduction in accidental cod catches. The decision also does not reflect the very low reported landings of this species. Declining weight and condition of plaice also warrant greater caution. The TAC must be combined with effective enforcement of mandatory selective gear to reduce cod bycatch and the implementation of the landing obligation. Annual fishing limits must support lasting recovery The Council’s decisions on Baltic Sea fishing opportunities for 2027 are not ambitious enough to secure restoration of all Baltic Sea fish populations. These decisions should be seen in the context of last year’s joint commitment by the European Commission and Baltic Sea Member States to seek dedicated scientific advice from ICES on rebuilding pathways for fish populations. In the absence of such rebuilding-oriented advice, and whilst we are waiting for it, decisions should be more cautious and based on the available recovery-focused catch options provided by the scientists in their traditional advice. Fisheries management must also support EU marine restoration objectives and the achievement of good environmental status in the Baltic Sea. Restoring fish populations and food webs is essential to the recovery of the sea itself and to the long-term future of Baltic fisheries and the coastal communities that depend on them.
