Why do you plant trees even where there are already trees?

In some of the areas we are restoring, the most valuable and oldest trees were usually cut down by previous owners. It is important to know that 50% of the biomass of a forest is concentrated in only 5% of the trees. Therefore, it can be useful to plant in existing forests, for example, to increase biodiversity. This is called “enrichment planting” and it helps to strengthen the ecological “immune system” of the forest system. In order to make the ecologically right decisions, Plant-for-the-Planet employs a team of nine ecologists (2021). Its task is to ensure that the increase in biomass and thus CO₂ sequestration is ecologically sound, while at the same time increasing biodiversity.
