摘要：This study was performed to investigate fire effects on some soil and biologic characteristics of Northern forests of Iran. The soil characteristics included soil moisture and soil particles. The biologic characteristics included leaf litter moisture and depth, forest ground cover and fallen trees. For this purpose, 70 samples of soil and leaf litter were collected in the burned and unburned areas. The sampling method was based on random-selecting method. The soil moisture and leaf litter moisture of samples were obtained by weighing the humid and dry samples in Soil Science Laboratory. Soil particles size was measured by hydrometer method in Soil Science Laboratory. For data analysis, the mean comparison test of two statistical societies was used because data include two groups (burned area and unburned area). Thus, Independent-Sample T test was applied to investigate the significant difference of soil and biologic characteristics in the burned and unburned areas. Results showed that there was a significant relation between mean of soil moisture, clay, silt and sand percent, leaf litter moisture, leaf litter depth and ground cover in the burned and unburned areas; while there was not a significant relation between fallen trees in the burned and unburned areas in this study.
