The sites are heterogeneous and have different degrees of degradation, resulting in different intervention needs and opportunities. It is crucial to understand which species appear in nature as groups and to design the planting design accordingly. Mother trees, flowering periods and storability of seeds need to be known and the planting has to be adapted according to suitable planting periods. In the nursery, the focus on good root systems of the seedlings is key, requiring appropriate nursing equipment, substrate and trained staff.
- knowledge, link to research and traditional knowledge
- capacities to collect seed material from the right tree for the right place and the right purpose
- sufficient funding and training capacities
Investment of time and funding in the above-named factors pays off in form of higher survival rates, better growth, and project success. Some aspects should not be compromised, for example the size of the seedling containers and the substrate.
