Definition and significance of marine nature conservation
Marine nature conservation refers to all legal, political, and administrative measures aimed at protecting and ensuring the sustainable use of the marine environment and its biodiversity. The primary goal is to preserve habitats, species diversity, and ecological processes in seas and coastal areas, while minimizing anthropogenic risks such as pollution, overfishing, or habitat destruction. Marine nature conservation has both national and international dimensions and is governed by a multitude of legal regulations.
Legal Foundations of Marine Nature Conservation
International Marine Nature Conservation Law
UN Convention on the Law of the Sea (UNCLOS)
The United Nations Convention on the Law of the Sea (UNCLOS, 1982) is the central international treaty and obligates the States Parties, among other things, to protect and preserve the marine environment (Art. 192 UNCLOS). According to Art. 194 UNCLOS, all States are required to take measures against pollution and to conserve marine fauna and flora. UNCLOS distinguishes between protection obligations in different maritime zones, such as the Exclusive Economic Zone, the territorial sea, and the high seas.
Biodiversity Agreements and Further Treaties
Other important international agreements include:
- Convention on Biological Diversity (CBD, 1992): Contains obligations for the protection of marine biological diversity.
- Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR, 1980): Regulates protection in polar marine environments.
- Convention for the Prevention of Marine Pollution from Ships (MARPOL, 1973/78): Serves to protect the seas from the introduction of various pollutants.
European Marine Environmental Law
Marine Strategy Framework Directive (MSFD)
Directive 2008/56/EC, known as the Marine Strategy Framework Directive (MSFD), obliges EU Member States to achieve a good environmental status of marine waters by 2020. The MSFD sets objectives for water cleanliness, biodiversity preservation, sustainable use and combating various threats to the ecological balance of the seas.
Other relevant EU legal acts
These include:
- Habitats Directive (92/43/EEC) und Birds Directive (79/409/EEC): Basis for the creation of Natura 2000 areas, which may also include marine areas.
- Water Framework Directive (2000/60/EC): It includes adjacent coastal waters and entails related protection and management obligations.
National Marine Nature Conservation Law in Germany
Constitutional Requirements
The Basic Law (GG) obliges the federal government and the states in Art. 20a GG to protect the natural foundations of life, including marine ecosystems. The legislative competence depends on the marine zone: federal (territorial sea, Exclusive Economic Zone – EEZ) or state (inland, coastal waters).
Federal Nature Conservation Act and EEZ Ordinance
Das Federal Nature Conservation Act (BNatSchG) forms the central legal basis for nature conservation in the sea. According to § 57 BNatSchG, this includes, among other things, the designation of marine protected areas. The Marine Protected Areas Ordinance regulates protection in the German EEZ based on § 57 para. 3 BNatSchG. The Federal Agency for Nature Conservation (BfN) is the central authority for these tasks.
State Laws and Marine Nature Conservation
In coastal waters, the respective federal states are responsible for marine nature conservation. Independent ordinances and administrative regulations are issued for this purpose, for example the Lower Saxony Implementation Act for the BNatSchG.
Instruments and measures of marine nature conservation
Designation of Protected Areas
A key instrument is the designation of marine protected areas:
- Natura 2000 areas: Include both Habitats and Birds Directive sites in the sea.
- National nature reserves: Designated in the German EEZ and territorial sea.
- Biosphere reserves and UNESCO World Natural Heritage Sites: Protect valuable marine habitats.
These protected areas are subject to specific usage restrictions regarding fisheries, mineral extraction, shipping traffic, and other activities.
Authorization and approval procedures
Projects with potential environmental impacts (offshore wind farms, cable routes, sand and gravel extraction) require an environmental impact assessment in accordance with the UVPG as well as a nature conservation permit based on the BNatSchG and specific protected area ordinances.
Monitoring and reporting obligations
The MSFD and national regulations require regular monitoring of the state of the sea, reporting, and updating of protective measures with significant public involvement.
Sanctions and enforcement
Legal violations (e.g., prohibition of impairment of protected areas or species) can result in regulatory fines, administrative or criminal consequences. Enforcement is carried out by specialized federal and state authorities with the support of the coast guard, waterways and shipping authorities, and, if necessary, the police and customs.
Current challenges and development trends
Current issues in marine nature conservation include:
- Increasing usage interests (e.g., offshore wind energy, shipping)
- Climate change and ocean acidification
- Increase of marine debris and microplastics
- Requirements for improved enforcement and international cooperation
At the same time, ongoing developments are taking place, for example through the adoption of new international agreements such as the UN High Seas Treaty (BBNJ) 2023.

Summary
Marine nature conservation is a complex and dynamic legal field shaped by a multitude of international, European, and national regulations. It plays a central role in preserving biological diversity, protecting ecologically sensitive areas, and ensuring the sustainable use of the marine environment. Its practical and legal requirements are subject to continuous development within the framework of international and national environmental policy.
Frequently asked questions
Which key international agreements govern the legal framework for marine nature conservation?
The legal framework for marine nature conservation at the international level is defined primarily by several key agreements. The most important document is the United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982, which establishes the fundamental legal order for the use and protection of the marine environment. UNCLOS requires parties to comprehensively protect and preserve the marine environment in Article 192. In addition, the Convention on Biological Diversity (CBD) plays a vital role by requiring the protection of marine ecosystems and the conservation of biological diversity, even in coastal and open-sea areas. Other important international instruments include the Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), the Ramsar Convention for the protection of wetlands, and the OSPAR Convention for the Protection of the Marine Environment of the North-East Atlantic. Regional agreements such as the Helsinki Convention (HELCOM) for the Baltic Sea or the Barcelona Convention for the Mediterranean supplement the legal framework. Concrete obligations range from the establishment of marine protected areas to regulations on pollution prevention, the conservation of endangered species, sustainable use of marine resources, and internationally regulated cooperation for monitoring and enforcing the norms.
How are marine protected areas legally defined and designated?
The designation and legal definition of marine protected areas (MPAs) is governed by both international and national law. The United Nations Convention on the Law of the Sea (UNCLOS) explicitly requires states to take measures for the conservation of endangered marine areas (e.g., Arts. 194, 197). At the European level, the Habitats Directive and the Birds Directive play a central role; under their provisions, Member States must designate the European Natura 2000 network—including in the sea. Nationally, designation is made by ordinances or laws specifying exact geodata, conservation purposes, prohibitions, and required management measures. The permissibility of human activities (e.g., fishing, shipping, energy production) within a protected area depends on the type of area (strict reserve, national park, biosphere reserve, etc.) and is restricted accordingly. Designation often requires extensive scientific justifications and is subject to participation and hearing procedures before it becomes legally binding. Monitoring and sanctioning of violations are carried out under specific sanction regimes.
Which national laws govern marine nature conservation in Germany?
In Germany, marine nature conservation is regulated by the interplay of several legal provisions. The main legal framework is the Federal Nature Conservation Act (BNatSchG), which in Sections 7 ff. provides the basis for protected areas, as well as species, biotope, and area protection. For the German Exclusive Economic Zone (EEZ, 12-200 nautical miles), there are specific EEZ nature conservation regulations anchored in the Federal Nature Conservation Act and implemented through individual ordinances of the Federal Ministry for the Environment (e.g., for Natura 2000 sites in the North and Baltic Seas). The implementation of the EU Marine Strategy Framework Directive (MSFD 2008/56/EC) in Germany is carried out through the Water Management Act and supplementary ordinances. Authorities responsible for marine nature conservation in the German part of the EEZ are the Federal Agency for Nature Conservation (BfN) and the Federal Maritime and Hydrographic Agency (BSH). For the coastal waters (up to 12 nautical miles), the nature conservation laws of the federal states apply.
How is the enforcement of marine nature conservation regulations legally ensured?
The enforcement of marine nature conservation regulations includes both preventive and repressive measures. From an administrative point of view, supervision is performed especially by authorities such as the BfN and BSH in the German EEZ, which can carry out surveillance flights, satellite monitoring, and inspections. If regulations are violated, administrative measures such as orders, requirements, fines, or even coercive fines can be imposed. Criminally, offences such as the illegal removal of protected species or causing serious environmental harm can be prosecuted under the Criminal Code (§ 329 StGB: “Water pollution”). Internationally, cooperation is established via Interpol Marine Pollution (IMPEL) and the OSPAR network for criminal prosecution. Most legal regulations for marine monitoring expressly provide for reporting and notification obligations, monitoring programs, and sanctioning mechanisms to ensure compliance.
What role do the European Union and its directives play in marine nature conservation?
Through its directives and regulations, the European Union sets binding requirements for marine nature conservation for its Member States. Key EU directives are the Marine Strategy Framework Directive (MSFD, 2008/56/EC), which aimed to achieve ‘good environmental status’ of marine waters by 2020, as well as the aforementioned Habitats Directive and Birds Directive, which establish the Natura 2000 area network in marine regions. These directives must be transposed into national law by Member States and require concrete protection measures, management plans, regular monitoring, and reporting obligations to the EU Commission. The EU can initiate infringement proceedings against States that do not comply with their obligations.
How is the balance between economic use and marine nature conservation legally structured?
The balancing of interests is based on environmental impact assessments (EIA), spatial planning procedures, and special permitting procedures as provided for by national and European legislation. For example, prior to the construction of offshore wind farms or other utilization projects, a comprehensive assessment of environmental impacts must be carried out under the UVPG (Environmental Impact Assessment Act) and the European EIA Directive. It must be thoroughly examined whether and to what extent the project collides with conservation objectives and how negative effects can be avoided, reduced, or compensated. The conservation status of protected areas holds particular significance. According to UNCLOS and the Marine Strategy Framework Directive, the protection of the marine environment is an integral part of all economic planning. The law also requires the involvement of relevant stakeholders and the public.
What are the most important legal sanctions for violations of marine nature conservation?
Violations of marine nature conservation regulations can be sanctioned administratively (fines up to several tens of thousands of euros, coercive fines, revocation of permits) and, in serious cases, criminally (imprisonment, large fines). The Federal Nature Conservation Act and relevant ordinances define the range of fines and the possibility of confiscating unlawfully acquired items. If someone intentionally or through gross negligence causes significant environmental damage as defined by § 329 of the Criminal Code, criminal prosecution is possible. Furthermore, in the European context, severe penalties and infringement proceedings by the EU with financial consequences for Member States can follow if they neglect their protection obligations. On the international level, UNCLOS provides for mechanisms of dispute resolution and sanctions, for example, through the International Tribunal for the Law of the Sea.
