Mosses (Musci) of Deirmenboaz› (Manyas District, Bal›kesir)

An evaluation of the phytogeography reveals that, the study area is located in the southern Marmara region and belongs to the European-Siberian flora area, but the existence of elements of Mediterranean origin as well in this area makes its floristic structure interesting. Woody taxa that are widespread in the area are connected with the frequently seen tree and bush types. The forest vegetation consists of mainly the following taxa: Quercus cerris L., Q. infectoria Oliv., Q. coccifera L., Q. frainetto Ten., Myrtus communis L., Juglans regia L., Sytrax officinalis L., Carpinus betulus L., C. orientalis Mill., Platanus orientalis L., Salix alba L., Morus alba L., Rosa canina L., Corylus avellana L., Populus nigra L., Ficus carica L., Paliurus spina-christi Mill., Alnus glutinosa (L.) Gaertn., Pyrus elaeagnifolia (L.) Pall., P. communis L., Fagus orientalis Lipsky, Ulmus glabra Huds., Arbutus andrachne L., Ceratonia siliqua L., Tilia tomentosa Moench., Acer campestre L., Hedera helix L., and Crataegus monogyna Jacq. Indeed, the Mediterranean type along the Marmara coast, the Mediterranean and the Black Sea elements on southern Marmara coast, damp forests on hillsides that are facing the northern parts of the mountains, and dry forests (Quercus spp.) on parts that are facing south are available (Atalay, 1994). Most of the study area is dominated by various types of oaks. The east part of the area is a coppice oak forest, and in the west hillsides are converted into high forest. In addition, the fact that the west part of the study area is threatened due to the construction of Manyas Dam means that protection is of great importance.
