Changes of soil properties and flora in natural forest and afforestation areas (Çankırı- Eldivan region)

Abstract

In this study, existing flora and its soil characteristics besides the silvicultural features of natural and cultured forest areas having ecological and topographic qualities alike were compared. Due to the fact that Turkey has so many different growing conditions, it is one of the most important geographical regions in terms of richness of plant species. The fact that diversity of these plant species are known, conserved and conducted in accordance with the complex relations among climate-soil and plant must be necessary. In the field of our research, the richest families are Fabaceae, Asteraceae, Lamiaceae, Brassicaceae, Poaceae, Scrophulariaceae, Boraginaceae Caryophyllaceae, Apiaceae and Rosaceae. The ratio of the richest ten families in total species 73.83%, and also the ratio of the rest 22 families is 26.17%. At the end of the afforestation efforts of 46 years, In spite of all negative characteristics, it’s shown that afforestation makes the soil approach to the natural forest soil.
