| Popis: | The study was conducted in Taftan rangeland in Sistan and Baluchestan, Iran, to study the effects of grazing exclusion on reclamation of vegetation cover and soil properties. After a comprehensive assessment of the vegetation types, plant sampling was carried out in sampling stands (50 × 50 m). In each stand, vegetation properties were measured using simple transect lines (50 m) method within quadrats (5 × 5 m), with a systematically randomized method. Soil sampling (75 samples) was performed along transects from the surface layer (0–30 cm). Results showed that livestock exclusion significantly affected community characteristics. The species richness (14.32), diversity (2.97), and plant cover (65.14%) showed their maximum level in the 15-year exclusion. The soil nutrient content increased during exclusion. Organic carbon (4.20%), total nitrogen (1.12%), available potassium (393.33 mg kg−1), and available phosphorus content (17.13 mg kg−1) attained significantly greater values under the long-term e... |
