species were then delineated on the map. In the delineation stage of the task aerial photography was 
used as well. 
2. STUDY AREA 
The study area, “ Citdere District “, is within the Yenice Forest Directorate, Zonguldak, Black Sea 
region, Turkey Figure 1. The elevation ranges between 640 m at Sekermese and 1704 m at 
Kuyrukkaya Tepesi, where the slopes are relatively steep and the terrain is treacherous. The region 
is included in the West Black Sea region macro climatic zone. According to the data obtained by 
the nearby regional meteorological station, the region can be classified among the zones where 
moisturise vegetation types grow, depending on the location and dominant plant species. There is 
not or is a little, if any, water shortage. In the study area, the soil depth is fairly high where the 
bedrock varies (sandstone, marn, limestone etc.). 
Citdere district is 6070 ha. (60.7 km”), 5431 ha of which is productive, 412.5 ha. Of which is not in 
terms of forest management applications. 234.5 ha. Are bare, open spaces. Citdere is very 
abundant in terms of tree, brush and grass species. Available forests can be classified as naturally 
well preserved, including both coniferous and deciduous species. 
3. DETERMINATION OF MAP UNITS 
To determine the forest vegetation types, 134 sample points were taken using Braun-Blanquet 
method (Figure 2). The approximate area of these sample points is 400 to 500 m“. All the plant 
species and the areas they cover within the sample point were measured and recorded. After the 
tabulation of these records, 14 tree and brush units were established. These are as follows: 
Fir - Beech forest mixed with Scotch pine. 
Monosses uniflora variant. 
Fir - Beech forest mixed with Ilex Colchica and Rhododendron ponticum var. 
Fir - Beech forest mixed with Ilex Colchica typical var. 
Yew - Beech forest. 
Hophornbeam — Basswood forest var. 
Oak forest (Quercus macrantera var.). 
Melamphyrum arvense (Rhododendron ponticum var. of Quercus petraea). 
Melamphyrum arvense (typical var. of Quercus petraea). 
10. Scotch pine - Black pine forest. 
11. Beech forest. 
12. Oak (Quercus hartwissiana) — beech forest sub-sub var. 
13. Circea lutetiana sub-sub var. 
14. Fir (Abies Bormulleriana var.) forest with Circea lutetiana sub-sub var.

Among these units number 3 and 12 with all their sup-species occupy more area than the rest of the 
determined units. The delineation of forest units and their apparent distinctions was both done on 
the field and from the aerial photography. During the field study, a 1:10,000 scaled map, which had 
been enlarged from a 1:25,000 scaled map, was used. 
Some units were evaluated as combined, and open spaces were included in some of these combined 
units. Finally, the following map units were established:
