This study was conducted to reveal the floristic composition of Yaylacık Research Forest (YRF), which is a part of Karabük Yenice Forests. Exactly 526 taxa belonging to 73 families were identified between 2004 and 2007. The number of endemic taxa was 21, and the rate of endemism was 4%. The International Union for Conservation of Nature (IUCN) classified the threat categories of the endemic taxa as follows: 1 taxon in data deficient (DD) category, 2 taxa in Vulnerable (VU) category, 4 taxa in near threatened (NT) category, and 14 taxa in least concern (LC) category. In the YRF, 39.3% (207) of taxa were included in Euro-Siberian, 4.4% (23) in Mediterranean, and 1.5% (8) in Irano-Turanian phytogeographical regions. The number of pluriregional or unknown taxa was 288, which constitutes 54.8% of the total number of taxa. Asteraceae (69 taxa; 13.1%), Poaceae (44 taxa; 8.4%), Fabaceae (43 taxa; 8.2%), Lamiaceae, Rosaceae, and Apiaceae (28 taxa; 5.3%), Brassicaceae (20 taxa; 3.8%), Caryophyllaceae (19 taxa; 3.2%), Plantaginaceae (15 taxa; 2.9%), and Orchidaceae (14 taxa; 2.7%) were the families with the most taxa in the study area. Genera with the most taxa were Hieracium (11), Trifolium (10), Veronica (10), Vicia (8), Galium (7), Campanula (7), Ranunculus (6), and Silene (6). In addition, Bromus, Carex, Epilobium, Euphorbia, Poa, Salvia, and Verbascum are genera represented by 5 taxa in the study area. In YRF, hemicryptophytes were ranked first (with 305 taxa), followed by Therophytes (86), Phanerophytes (56), Cryptophytes (55), Chamaephytes (17), and parasitic plants (7). [ABSTRACT FROM AUTHOR] |
