SUBSTANCE: invention relates to forestry, in particular agro-forest amelioration, and can be used for afforestation in arid, for example, chalk slopes having soil cover. The method comprises mapping the reafforesting area, digging trenches in rows across the slope with the depth greater than the soil layer, stacking the excavated soil into the trenches, and the rest of the soil near the trenches down the slope, planting of woody plants. Soil of the slopes and bottom of the dug trenches is compacted. In between the rows a part of the soil layer is cut and the trenches are filled with it to form a roll. The soil remaining in between rows is compacted. The woody plants are planted in spring in the formed roll. The soil in the trenches and the soil between the rows is compacted to a density providing maximum water-holding capacity. The soil in between the rows is compacted during the growing seasons before closing crowns in between the rows.
