Transitional (brackish) water bodies host extremely vulnerable ecosystems. They are highly sensitive to pollution, changes in the water currents, nutrient levels, etc. Over the course of the 20th century in Bulgaria, many of them were purposely drained or strongly altered. Today, these fragile ecosystems account for just 0.1% of Bulgaria’s area, and hence they are listed among the country’s top priority nature conservation sites. The long-term preservation and survival of numerous rare or threatened hydrobionts de...

Over 30% of the Bulgarian Black Sea shoreline is characterized as a depositional type of coast. A significant portion of it represents well-formed sandy beaches and dune fields, falling under the protection of the European ecological network NATURA 2000. The coastal sector of the Lower Kamchia Depression hosts the longest beach-dune system on the Bulgarian Black Sea coast called Kamchia-Shkorpilovtsi beach. The main task of the project "Mapping and monitoring of depositional areas along the Northern Bulgarian Blac...
