Migratory Species and the Importance of Via Pontica for Black Sea Biodiversity

Migratory species play a critical role in maintaining ecosystem balance across continents. Every year, millions of birds travel along migration corridors connecting Europe, Asia, and Africa. One of the most important of these routes is Via Pontica, the Black Sea migratory flyway passing through Bulgaria’s coastline and wetlands.

Recent international biodiversity assessments continue to raise concerns about the condition of migratory species worldwide. According to reports connected to the Convention on Migratory Species, one in four migratory species is currently threatened with extinction, while several migratory bird populations continue to decline due to growing environmental pressures.

The Via Pontica corridor remains essential for seasonal migration and supports hundreds of thousands of birds every year during breeding and migration periods. Wetlands, coastal lakes, and protected habitats along the Black Sea coast provide critical resting, nesting, and feeding areas for migratory species.

Environmental threats affecting migratory populations continue to increase across the region, including:

• habitat fragmentation

• wetland degradation

• pollution

• infrastructure expansion

• climate-related ecosystem changes

Long-distance migratory species are especially vulnerable because they depend on multiple ecosystems across several countries during their annual migration cycles. The loss or degradation of even a single stopover site can affect populations across entire migration routes.

For the Protection of Biodiversity in Bulgaria Foundation, the protection of Via Pontica is directly connected to long-term biodiversity conservation, wetland protection, and sustainable environmental planning in the Black Sea region.

Scientific monitoring, international cooperation, and ecosystem-based conservation policies remain essential for protecting migratory species and preserving ecological connectivity across borders.
