In recent decades, the use of off-road vehicles (ORVs) for challenging outdoor trips has increased significantly worldwide, impacting soil, vegetation, and wildlife. This study was conducted in Sde Zin, Israel, a hyper-arid desert zone. The area has a high concentration of trails created unintentionally over the years by ORVs. The study sought to examine whether the degraded trails will be restored naturally or if there is a need for active intervention. Five ORV trails were selected, with a plot of 40 x 15 m in each trail, comprising three subplot treatments: one session of disk tillage, no tillage, and an adjacent control subplot. Soil and vegetation parameters were measured for two consecutive years. The results indicated that the measured soil parameters did not differ between treatments except for the degree of soil compaction, which was a significant factor in plant survival and restoration. The highest H ' Shannon diversity was found in the disk-tillage treatment, where the plant assemblage differed from that of the non-tillage and control subplots. The conclusion derived from this study is that active management to prevent soil compaction is needed in severely degraded desert areas to stimulate soil and vegetation restoration processes.
