Tree growing projects just exist as group projects, because they can be quite expensive in the beginning. That means the money which brings this projects up comes from the group fond. So the profit goes also back to the group fond. The work is divided among the members, the ones who are not working directly on the field, support the Project with money.
So far there are just two different kinds of trees which are used for these projects – eucalyptus trees and pine trees. In the case of eucalyptus trees it takes 2 – 3 years until they can be harvested. The wood from these trees is mainly used as building material and firewood. In the case of pine trees it takes ? – ? years. This wood can be used in many different ways.
The biggest challenge are the, especially in the last years, changing climate conditions, e.g. long droughts and long heavy rains, which can destroy the fields.
