Scots pine forest properties will help us in obtaining information about how to use the forests within the system and about their capacity, as well as learning their bio-ecological features. Such information will support the knowledge about their protection and use conditions. This study aims to reveal the bio-ecological characteristics of the Igdırdag and Sisorta scots pine forests in Koyulhisar. Also, to compare two scots pine forests in terms of their characteristics. Five stations were determined in each forest. The geographic position was determined with GPS and 15 scots pines were randomly selected for each station. The age, the bark thickness, the tree height and the diameter were measured. The amount of accumulated litter on the soil surface and the physical properties of soil were also determined in the laboratory. Sisorta scots pine forest had higher elevation and lower slope, and also, scots pine tree in Sisorta has larger diamter. In terms of soil properties, the soil of Igdırdag scots pine forest had higher lime content than Sisorta scots pine forest. Aspect of each station in two forests is different from each other. The two forests had similar properties for scots pine properties except diameter. Similarly, soil properties except lime content show homogeneity. Aspect and slope of each station could be cause those differences. The more researcher stated that shading aspect is positively effect on site index for different species. In conclusion, Koyulhisar scots pine forests is healty. The increasing human population has a negative impact on the forest and the establishment of new forests is unavoidable.

In this study, the dynamism of forest areas was tried to be determined by determining the ecological differences between the areas where Fagus orientalis Lipsky. (Eastern beech, Fagaceae), a very important species for forestry in Turkey, and the soils of agricultural fields. lime %, total salt %, pH, texture, field capacity %, C%, N%, C/N ratios, 30-day carbon mineralization of the lands of Eastern beech forests and agricultural fields, which are naturally formed in Sivas province Koyulhisar district, under controlled conditions (28°C, 80 humidity %) was determined by the respiration method, and two areas in two different ecosystems were compared. When the carbon mineralizations of eastern beech soils were examined seasonally, it was determined as 19.54>18.23>17.87>17.18 mg C(CO2)/100g DS/30 day in spring>autumn>summer>winter seasons, while it was determined as 14.46>13.87>13.68>13.65 mg C(CO2)/100g DS/30 day in autumn>summer>spring>winter seasons in agricultural soils, respectively. Significant relationships were found between the C%, N%, 30-day carbon mineralization cumulative values and % carbon mineralization rates between both areas.
