Positive effect of soil preparation on the number of emerged oak plants was confirmed. With insufficient light the natural seedlings die rapidly even under open canopy (0.80); this rate increases due to shading by the trees of lower storey (hornbeam, linden, hazel), and the seedlings are incapable of maintaining themselves under this shelter more than 6-7 years. For maintaining and further surviving of high quality oak natural seedlings it is necessary (best immediately after the seed year) to open lower storey and to reduce the shelter formed by parent stand to the value of an open canopy (0.60). It creates a precondition that the oak natural seeding would maintain itself in the stand, and would be, if only by sporadic crops, completed
