Özet
Releases of CO2 from forest soils was studied relative to different timberharvesting techniques, slope classes, and stand age. Three timberharvesting techniques (suspended skidding (SS), skidding by using askidding cone (SC), and cable-pulling (CP)) were used in young andmature black pine stands at three different slopes (0 to 20%-S1, 20% to33%-S2, and > 33%-S3). Soil respiration measurements were carriedout at five-day intervals (1st, 5th, and 10th day) and 6 months later after thetimber harvesting techniques. The soil respiration increased on the firstday, decreased on the 5th and 10th days, and reached its lowest level onthe 6th month. The SC technique in the young stands showed the highestsoil respiration value on the slopes indicating that the cone placed on thehead of the log during the skidding operations does not deform the soil. Inthe mature stands, all timber harvesting techniques and the undisturbedsites showed lower values than in the young stands on the S1. On the S2,mean value was higher in the mature stands. In contrast to the youngstands, the undisturbed stands had the highest soil respiration.
