Effect of grazed and surface scrafication on soil properties and regeneration in centeral Zagros forests (Case study: Aleshtar city forests)

In order to study the effect of grazed and soil surface scrafication on regeneration and soil physical and chemical properties in Zagros forests, three areas including preserved woodland with soil scrafication, preserved woodland without soil scrafication and no preserved woodland in forests of Aleshtar in Lorestan province were choosen. Soil sampling and seedling counting were done using random sampling. Ten sample plots were selected in each study area and soil properties and number of seedlings were studied in plots. The most important physical and chemical soil properties were analysied in lab. The results of One-Way ANOVA showed significant differences in Bulk Density (BD), Particle Density (PD), C, P, K and N between study areas. The results of this research indicated the number of seedlings in preserved and no preserved woodlands differed significantly. The correlation between soil properties and regeneration showed considerable effects of the grazed and soil surface scraficationon on soil properties and the number of regeneration. These results indicated that these two approaches can be considered as capable management strategies in revival of Zagross forests.
