In order to guide the selection of seed sources adapted to a particular restoration site, maps with seed transfer zones (or seed zones) were developed.
Seed transfer zones define areas within which planting material can be moved and used with a minimal risk of maladaptation and disruption of genetic patterns.
The seed transfer zones illustrated in the map are the result of a cluster analysis based on soil and climate variables. In order to predict possible changes in the distribution of seed transfer zones under different scenarios of climate change, the current map has been projected to different climate change scenarios (RCP4.5 and RCP8.5) over different time horizons (2050 and 2070). If the most suitable seed transfer zone for a restoration site is expected to change in the future, it is recommended to source planting material from areas within the current seed transfer zone as well as from the seed transfer zone predicted under future conditions.
