You have an obligation to restock woodland when the increment is not utilized. You are obliged to use established methods and tree species that are suitable for the site. Restocking can be done through planting, seeding or natural regeneration. In most cases you must perform soil treatment to get a satisfying result. All measures must be completed during the third year after harvest, at the latest. If the number of plants is too few after having regenerated, you have to restock the plants before it is too late. If, on the other hand, there are too many plants you might have to give plants space through a pre-commercial thinning.
