    Determination of pesticide residues in water and soil resources of Troia (Troy)
    (Parlar Scientific Publications (P S P), 2007) Yildirim, Ismet; Oezcan, Hasan
    This study was carried out in the Troia (Troy) National Park, a secondary bird migration corridor on the North-South axis in northwest Turkey, which was proclaimed a national park in 1996, and a world cultural heritage in 1998 by the UNESCO on account of its archeological richness. The aim of this study was to determine the residues of widely used pesticides, such as alpha- and beta-hexachlorohexane (HCH), heptachlor, aldrin, alpha- and beta-endosulfan, endosulfan sulphate, methoxychlor, endrin, dieldrin, fenthion, azinphosmethyl, malathion, methamidophos, diazinon, trifluralin, malathion, captan, cypermetyhrin, ethion, and mancozeb in soil as well as surface and ground water resources. Methoxychlor, alpha-endosulfan, beta-endosulfan, alpha-HCH and beta-HCH were detected in water samples collected from 13 sites in 4 different water resources between May and August 2003, whereas HCH, ethion, endosulfan, captan, trifluralin and mancozeb residues were found in soil samples taken according to plant patterns from 14 different sites at depths of 0-20 cm in August 2003. The residues of alpha-endosulfan were higher than the others, and ranged between 0.079-1.8 ppb, with an average of 0.369 ppb in May, but 0-8.3 ppb, with an average of 0.954 ppb in August. The dominant residue in soil samples was HCH (0-49 ppb), with an average of 10.07 ppb. It was concluded that the observed decrease in species and number of migratory birds in the region could be a result of the amount of pesticide residues in both water and soil resources, originating from intensive agricultural applications.

    Ecotourism Potential and Management of Kavak Delta (Northwest Turkey)
    (Coastal Education & Research Foundation, 2009) Oezcan, Hasan; Akbulak, Cengiz; Kelkit, Abdullah; Tosunoğlu, Murat; Uysal, Ismet
    Wetlands are ecosystems where a high level of biodiversity is found. Being a suitable medium for the nourishment, reproduction, and accommodation of many species of living creatures, wetlands are museums of natural riches, not only of the country where they are located but also of the whole world. Kavak Delta, one of the most important wetlands of Turkey, with coastal dunes and halophilic vegetation as well as being on the north-south bird migration route, provides not only opportunities for coastal tourism but also offers substantial potential for ecotourism. During observations, bird species, especially of the orders Anseriformes, Falconiformes, and Charadriiformes, were identified. Some 14 orders, 39 families, and 124 bird species were spotted in the delta. Also, dune and halophilic plants constitute a rich flora in the delta. In this study, the potential for ecotourism and opportunities for coastal tourism in the area are outlined. Within this context, besides ecotourism activities, such as bird observation, botanic tourism, and angling, the use of beaches for coastal tourism is determined. Various recommendations are made for the optimal use of all tourism opportunities detected in the delta and for enabling sustainable coastal use and management.
