After an initial trial of natural reforestation in 2016 on a small plot of land, a further 14 hectares were reforested with natural forest in 2017 and 2018. Where the land was already becoming bushy, reforestation lines with larger distances were planted in still existing grass areas as a supplement to the natural regeneration. Where the land was still completely overgrown with pasture grass, different planting densities were tried together with biologists. In this first major natural reforestation project, we were able to gain a lot of experience in terms of tree species, maintenance, care and other challenges.
