Short Term Impacts of Harvesting 0perations on Soil Chemical Properties in a Mediterranean Oak Ecosystem

Soil physical and chemical properties can be seriously affected by forest operations. There is a knowledge gap on this topic for oak ecosystems, which play significant role in the context of multiple-use forestry. The main objective study was to analyse floor topsoil changes (0–10 cm) two years after application small-scale thinning (50% reduction basal area) clear-cut operations using mules carry harvested material Northern Greece (Quercus frainetto Ten)ecosystem. total amount (O1+O2 horizons) reduced 37.8% thinned 30.8% plots compared control plots. These large reductions are mainly due O2 horizon treated Decomposition plots, possibly new drier conditions. Treatments increased soil pH but not extent. No evidence erosion found experimental protective function use designated mule trails. areal extent compaction limited only 3% area careful planning implementation animal skidding. Small differences C (%) Ν were among control, limiting growth factors Mediterranean ecosystems depth seasonal change moisture, especially during summer dry period. More research definition optimum degree extraction systems similar will important satisfy need improve characteristics.
