Monitoring of restoration treatments effect on vegetation performance Case study: Silvana rangelands in West Azerbaijan province

This research was aimed to investigate the effects of range improvement treatments on vegetation performance. The study was conducted in Silvana rangelands, West Azerbaijan province. In this study, four improvement treatments including contour furrow, pitting, gabion and mortar stone dams were selected. A control site (with no improvement treatment) was also selected. Vegetation sampling was done in a random-systematic manner in key areas of each site. Vegetation parameters including production, canopy cover percentage, litter and density were measured Data were analyzed by one-way ANOVA. Then, the mean values of parameters were compared with each other using the Duncan test. Statistical analysis was done in SPSS software. The results of one-way variance analysis indicated that the study mechanical improvement treatments had significant difference in terms of performance of plant parameters. According to the results, among the study treatments, contour furrow and mortar stone dam had the most positive impact on increasing and improving the performance of plant parameters, compared to other treatments in Silvana region.
