More and better harvesting opportunities for the production of autochthonous forest seedlings
In order to achieve the Flemish policy objectives for forest expansion by 2030, there is a need for sufficient suitable forest planting material. On behalf of Natuur en Bos, INBO has spent the last two years analysing the most important seed orchards of native origin in Flanders. These are orchards where seeds (plant reproductive material) are harvested to produce forest plants that are traded under the label ‘Plant van Hier’ (Plant from Here).
INBO evaluated the condition of 24 shrub and tree species in 74 different seed orchards. Using field observations, old management and planting plans, and literature, we drew up recommendations for each location and species to keep the seed orchard as productive and healthy as possible. In addition, INBO produced thousands of new plants of nine different species from material from these seed orchards. This was done by cuttings and grafting. The aim is to establish new seed orchards at private tree nurseries.
The results of this project will increase the harvest potential and production of forest plants in the future. We are also continuing to work with species that are currently less available. In this way, we are anticipating new demands from the forestry and nature sectors and can ensure sufficient harvest potential for these species in the long term.
