Planting or rather direct sowing?
After harvesting or a storm damage, it is necessary to think about finding the most suitable plantation areas within a specific location. In addition to the natural regeneration, reforestation must be considered. In forestry, afforestation means the planting of trees or the direct sowing of seeds as part of a forestation programme.
Direct sowing is a cost-effective addition to nature rejuvenation. Direct seeding is particularly interesting and a good alternative in smaller areas, e. g. bark beetle gaps, where sufficient light and heat can reach the ground. However, after forest fires the condition of the soil is suitable for direct sowing even without specific soil treatment. On surfaces where there is no more vegetation and layers of straw and humus are burnt, mountain pine and white pine seeds produced very good results.
When you go for direct sowing you save on transport and planting costs, which is a huge benefit. A further advantage is that the seed can germinate at the place where the plant will stay for its entire life. Direct sowing is also ideal because there is no need for the plant to adapt to a new climate or terrain or to different water and nutrient conditions, which is all relevant when planting young plants. Damage caused by planting mistakes (root deformations) or planting shocks are also no issue in the case of direct sowing.
Since direct sowing is only possible if the bare area is not or only slightly weedy, the reforestation success rate is generally much higher when planting young trees. Therefore direct sowing is most of the time the preferred option. Ultimately, the decision as to which method is used for afforestation depends on the respective circumstances. Each method has advantages and disadvantages and must be evaluated according to each specific case.
