The case study, Igneada Longos forest national park

The Igneada Longos Forests National Park, located on the Black Sea coast 15 km from the Turkish-Bulgarian border, is positioned between the northern latitudes 41′ 44′ 43′ and 41′ 58′ 27′ and the eastern longitudes 27′ 44′ 52′ and 28′ 3′ 17′.The Igneada area includes different kinds of ecosystems (sand dunes, wetlands, longos (flooded alluvial) forests, deciduous forests, and many streams) and a wide range of biodiversity; these characteristics make it one of the most important areas in Turkey (Ozyavuz, et al., 2006) (Table. Igneada and the surrounding environment have unique characteristics; these types (Igneada Longos Forests) of wild forest in other parts of Turkey and in Europe have been damaged due to anthropogenic effects (Figure 4).

Typically, flooded alluvial forests have high biological diversity, high productivity, and high habitat dynamism (Hughes et al., 2003). The surface area of these forests is around 3000 ha. Igneada alluvial longos forests are part of the Istranca forests; they are indeed ”natural treasures” that have been formed by several ecosystems over thousands of years (Ozyavuz and Yazgan, 2010).

There are five lakes in the area. Lake Erikli Lagoon (43 ha) is adjacent to the northern part of I gneada subdistrict, which is not linked with the sea during the summer period. Lake Mert (266 ha) is located at the southern part of the subdistrict, where the stream reaches the Black Sea. Lake Saka, which is the smallest (5 ha), is at the southernmost part of the study area between the forest and sand. Lake Hamam (19 ha) and Lake Pedina (10 ha) are located in the inner part. The coastal dunes and the longos forests of Igneada constitute the most sensitive ecosystem in the study area. Most of the known endemic plants (Silene sangaria, Crepis macropus, Centaurea kilaea) in Igneada and its vicinity are found in the coastal dunes; other species found here, though not endemics, are of national and international concern (Aurinia uechtritziana, Cakile maritima, Cionura erecta, Crambe maritima, Cyperus capitatus, Elymus elongatus subsp. elongatu, Eryngium maritimum, Euphorbia peplis, Eu. paralias, Jurinea kilae, Leymus racemosus, Otanthus maritimus, Pancratimum maritimum, Peucedanum obtusifolium, Stachys maritima) (Figure 5-10) (Ozyavuz and Yazgan, 2010).

There are three longos forests in the area. The conserved natural longos forests in the study area are the Lake Mert longos (316 ha), Lake Erikli longos (456 ha), and Lake Saka longos (624 ha) forests (Figure 11-13) This type of ecosystem is unique and rare in Turkey and the world because these ecosystems are sensitive to environmental conditions. In general, deciduous mixed forest vegetation is found in the area outside of the longos forests, and in this area the forests have similar floristic composition to the longos forests. However, slopes are rather steep in the area where these forests are found, and therefore the water table is well below the surface. The different ecosystems in the area provide a diverse living environment for the fauna in the region. Nearly half (194) of the 454 bird species constituting the bird diversity of Turkey are seen in this area during the year (Ozyavuz and Yazgan, 2010).
