THE FLORA OF DIKME UPLAND AND SURROUNDINGS, BINGOL (CENTER).

Abstract

This research was carried out to determine the flora of Dikme upland and surroundings, Bingol (Center). 1255 plant specimens were collected from the research area. 337 genera and total 707 taxa belong to the 75 families were determined. From these, 3 taxa belong to Pteridophyta, 704 taxa belong to Spermatophyta division. Coniferophyta and Magnoliophyta subdvisions in Spermatophyta include 4 and 700 taxa, respectively. In Magnoliophyta subdivision, 595 taxa were determined in Magnoliopsida and 105 taxa were determined in Liliopsida class. In the research area, 75 endemic taxa were determined and endemism ratio is 10.6%. The distibution of phytogeographic elements is: Irano-Turanian 252 (35.6%), Mediterranean 30 (4.2%), Euro-Siberian 46 (6.5%), Euxine 4 (0.5%) and multiregional or unknown phytogeographic elements 372 (52.6%). In addition, in our study the distribution of 38 plant taxa which are unknown in B8 square to this day were detected to have distribution in this square; habitat characteristics, variations and interesting distribution of some taxa also revealed with this study. Threatened categories are also proposed for the 23 endemic taxa according to IUCN categories. The distribution of the endemic and rare 23 taxa according to the red data as follows; 1 taxa in endangered “EN”, 3 taxa in vulnerable “VU”, 15 taxa in least concern “LC”, 3 taxa in near threatened “NT” and 1 taxa in data deficient “DD”. The largest ten families in the studied area were found as following: Asteraceae (99), Lamiaceae (64), Fabaceae (59), Poaceae (52), Brassicaceae (49), Boraginaceae (35), Caryophyllaceae (34), Apiaceae (31), Liliaceae (27), Scrophulariaceae (22). The largest ten genera in the flora region were: Astragalus L. (19), Silene L. (12), Centaurea L. (11), Salvia L. (10), Euphorbia L. (10), Vicia L. (9), Trifolium L. (9), Scrophularia L. (7), Stachys L. (7), Anthemis L. (7).
