a greater chance of germination compared to smaller seeds. Using 30 progenies per mother tree
and combining the progenies from five populations would provide a stand of 1500 individuals.
In addition to the genetic considerations, stand sizes should be kept at a manageable level and
that the burden of future management and regeneration is within the capacity of the institution
in charge. A minimum of 10 ha is recommended. Initial planting may want to consider planting
2000 individuals (40 progenies per mother tree) because this number will decrease as a result
of mortality and other factors.
