Between August 27th and September 30th 2014 the intensity of nocturnal bird migration was measured in the Dobrudzha Region (NE Bulgaria) using a specific bird radar. During the same time period and in the same area (part of Natura 2000 net BGSPA0002051 Kaliakra and adjacent areas), road-kills as well as collisions of birds with wind turbines were r...

The Institute of Biodiversity and Ecosystem Research at the Bulgarian Academy of Sciences (IBEI-BAS) has completed the implementation of the WEMA project "Wetlands Ecosystem Services Mapping and Assessment in Bulgaria", funded under the Financial Mechanism of the European Economic Area. The project is funded under the BG03 Program Biodiversity and Ecosystems under Call BG03.02: Mapping and Assessment of Ecosystem Services. Organized and analyzed ecological and biological scientific information on wetland ecosystems outside the Natura 2000 network in Bulgaria. The collected information will be integrated into the Information System of the National Biodiversity Monitoring System of the Executive Environment Agency. The project activities are carried out under the “Methodology for assessment and mapping of WETLAND ecosystems condition and their services in Bulgaria” (Part B7), developed under the MetEcosMap project “Methodological Assistance for Ecosystem Assessment and Biophysical Valuation”. Object of mapping and assessment of the condition and services provided were the following subtypes of "terrestrial wetlands" ecosystems: 1 / Valley mires, poor fens and transition mires (D2); 2 / Base-rich fens and calcareous spring mires (D4); 3 / Sedge and reedbeds, normally without free-standing water (D5). The main results are: • 285 "Terrestrial Wetlands" ecosystems identified and mapped through GIS and field studies; • The condition of identified ecosystems is assessed by direct measurement or analysis of available data on plant and animal diversity, soils, waters, fires, dumping-grounds and invasive species; • Assessed provisioning, Regulating/Maintenance and Cultural ecosystem services; • Individual maps of sub-types of ecosystems, their condition and the ecosystem services they provided; • The information gathered and the assessments made are entered in a database.
