COMPARING VEGETATION STRUCTURES OF EXCLOSURE AND GRAZED RANGELAND (CASE STUDY : TR-ABZON DUZKOY DISTRICT) ABSTRACT Uncontrolled and overgrazing in Turkey's rangeland have led to destruction of rangeland communities for many years. Determining results caused by grazing pressure has importance in terms of rangeland improvement practices. In this stud...

Öz In this study, it is aimed to determine the potential erosion risk condition of the area using remote sensing techniques and RUSLE method in Halfalı Stream Watershed, which is 25 km away from Kahramanmaras province. With the purpose of applying this method, rainfall erosivitiy index (R) has been generated by means of modified fournier index (MF...

Turkey is one of the countries that have highest rate of soil erosion due to negative topographic structure, soil and climate characteristics along with the problems caused by improper land use practices. Besides other negative effects, soil erosion is the source of sediment that fills reservoirs and thus shortens economic life of dams. Therefore,...

Skidding logs from stump to landing areas is one of the most important procedures in ground-based logging operations. Rubber-tired skidders often increase soil compaction, which leads to an increase in soil strength (penetrometer resistance) and bulk density (dry soil weight per volume). Woody slash materials (tree limbs and tops) are generally dis...
