Within the marine areas bordering Turkey’s lengthy coastline is found an abundant, highly diverse and globally significant biodiversity endowment. Overall, some 3,000 plant and animal species have been identified in Turkey’s territorial sea. Economically important fish species include anchovy, horse mackerel, bonito, sardine, bluefish, mullet and turbot. The major threats facing Turkey’s marine areas are habitat degradation associated with uncontrolled and fast coastal development.Protected areas have a potentially significant, yet largely unrealized, role to play in eliminating these threats to marine area biodiversity in Turkey. Currently, about 2.8% of Turkey’s territorial waters is protected.
The Project is executedby theMinistry of Environment and Urbanization through the General Directorate for Protection of Natural Assets. (The partnersare the Ministry of Forest and WaterAffairsthrough the General Directorate of NatureConservation and NationalParks and the Ministry of Food, Agriculture and Livestockthrough the General Diractorate of Fisheries and Aquaculture)The proposed long-term solution for marine biodiversity conservation in Turkey’s territorial sea is a reconfigured MCPA network designed to protect biodiversity while optimizing its ecological service functions – under effective and sustainable adaptive management. This long-term solution is seen to rest on three main pillars. First, the solution depends on adequate capacities on the part of key management agencies to identify, and focus suitable management efforts on, highly sensitive and/or biologically significant areas within the existing MCPA structure, while also being able to target gaps in representation that can be filled through MCPA expansion. Second, it requires a system of sustainable financing involving the integration of sustainable financing mechanisms and the application of economics into the planning and management of MCPAs. Third, the solution needs to be based on effective mechanisms for inter-sectoral co-operation that bring to bear the relevant strengths of various management agencies and branches of Government and civil society to solve marine biodiversity conservation challenges. The key barriers to the long-term solution act by preventing the emergence and operation of the above three pillars.
(“SEPA” stands for Special Environmental Protection Area. It is one of the MCPA status by Turkish law. These areas were managed by the executing agency: the General Directorate for Protection of Natural Assets. The other project site the AyvalikAdalari Nature Park is managed by the General Directorate of Nature Conservation and National Parks.)Turkish MPA system only lies within the Mediterranean - covering the Aegean Sea as well – coats of Turkey. No MPAs exist on the coasts of the Sea of Marmara nor in the Turkish Black Sea. This is one of the reasons why these MCPAs were selected for the Turkish Project. In addition, the project executing agency which has around 70% of the MCPAs management in Turkey is selected to execute this project at their PAs. Moreover, at these selected PAs baseline biodiversity and socio-economy studies were availablefor management preparations. Therefore ease the project implementation for the enhanced effective management.
For an optimum growth Posidonia needs transparent waters. For this reason, the presence of dense and large meadows is a clear sign of the quality of its waters. It’s endemic yet very restricted in the Mediterranean due to anthropogenic disturbances - constitute 3% of the basin. This corresponds to a surface area of about 38,000 square kilometer. It is found at depth ranges of 5 to 50 meters.
Marine vegetation including the Posidoniaseagrasses, store Carbon mainly in the organic soil. Over 95%–99% of total carbon stocks of seagrasses (& tidal marshes) are stored in the soils beneath them. This is different than forest ecosystems where the C stocks are usually higher in the living biomass.
The total surfacearea of Posidoniameadows in Gokova SEPA is calculated at 13 km2 (1300 ha).
The total surfacearea of Posidoniameadows in Foca SEPA is calculated at 6,7 km2 (670 ha).
This slide gives the information on the total blue carbon value for the project sites, and extrapolates this value 5,367,148 USD (161,071 ha) to all national system covering 346,138 ha (including the 105,922 ha new MCPAs established by the project).
