Overview

Monaco's marine conservation strategy reflects the Principality's recognition that its Mediterranean location provides both opportunities and responsibilities for ecosystem protection. Despite Monaco's tiny land area, its territorial waters and influence over regional marine policy create significant conservation impact.

The Mediterranean Sea faces numerous pressures including overfishing, pollution, shipping traffic, and climate impacts. Monaco has positioned itself as a leader in marine protection through international partnerships, research investment, and strict local regulations.

Pelagos Sanctuary

Establishment & Scope

The Pelagos Sanctuary (Sanctuary for Mediterranean Marine Mammals) was established through an international agreement between Monaco, France, and Italy. The sanctuary encompasses 87,500 km² of Mediterranean waters, making it one of Europe's largest marine protected areas.

Geographic Coverage: The sanctuary extends from Monaco eastward along the French and Italian coasts, encompassing critical cetacean habitat in the northwestern Mediterranean.

International Governance: The sanctuary operates under a tripartite agreement with coordinated management by all three nations. Decision-making involves:

  • The Pelagos Sanctuary Directorate
  • National representatives from each signatory country
  • Scientific advisory committees
  • Regular intergovernmental meetings

Cetacean Protection

The sanctuary's primary focus is protecting marine mammals, particularly cetaceans that migrate through and inhabit Mediterranean waters.

Species Protected:

  • Fin whales (Balaenoptera physalus)
  • Sperm whales (Physeter macrocephalus)
  • Bottlenose dolphins (Tursiops truncatus)
  • Common dolphins (Delphinus delphis)
  • Striped dolphins (Stenella coeruleoalba)
  • Risso's dolphins (Grampus griseus)
  • Harbour porpoises (Phocoena phocoena)

Regulations Within Sanctuary

Activities within Pelagos are regulated to minimize harm to marine mammals:

Shipping:

  • Modified shipping lanes to reduce vessel-strike risk
  • Mandatory speed restrictions in high-density cetacean areas
  • Reporting requirements for marine mammal sightings
  • Routing recommendations to avoid known aggregation zones

Fishing:

  • Restrictions on net types in certain zones
  • Regulations on fish aggregating device (FAD) deployment
  • Seasonal closures during migration periods
  • Reporting of cetacean bycatch incidents

Tourism:

  • Approach distance requirements (minimum 300 meters in most cases)
  • Behavioral guidelines for marine wildlife observation
  • Restrictions on vessel speed near marine mammals
  • Training requirements for wildlife observation tour operators

Marine Protected Areas in Monaco Territory
