The article deals with the seeding of silver fir under young silver birch stands and at the same time seeding of fir with birch in clearings. The patches seeding under a birch stand (site: Fagetum mesotrophicum) of about 20 years old was carried out in the autumn of 2018. In the same year, patches seeding of fir and birch were carried out on two clearings (site: Querceto-Fagetum mesotrophicum; Abieto-Fagetum mesotrophicum). Subsequently, in 2022, patch and pile seeding of fir and birch was conducted on two additional clearings (site: Abieto-Fagetum oligomesotrophicum; Piceeto-Abietum variohumidum acidophilum). Five years after experiment establishment a silver fir seed yield under birch stand reached 7.2%. In case of clearings silver fir seed yield ranged from 0% to 2%. In contrast to seeding fir under the birch stand, direct seeding of fir in the clearings cannot be considered a suitable restoration method, even when combined with birch seeding.
