Maintenance of genetic variation is one of the major objectives for
conserving endangered and threatened species [32]. Knowledge of
genetic variation between and within populations provides essential
information in the formulation of appropriate management strategies
directed towards their conservation [33]. From the results obtained in
this study it is possible to draw inferences on the conservation of
M. wufengensis. Given that the genetic structure of M. wufengensis has
high genetic diversity, high gene flow and low population divergence
suggest that genetic drift is not currently of great concern for this
species. However, during the past few decades, most habitats have
been exploited for mono-culture plantations. This tree has been
over-exploited for timber and ornamental use, severely threatening
this species, even though the medicine use may probably helped
the survival in past time. Many trees are now scattered along
roadsides where habitats are accessible. Furthermore, according
to the finding of pollen flow and effects of the population structure
of Magnolia stellata, population fragmentation is associated with
population size decreasing and increasing geographic separation of the
populations, which reduces its reproductive success rate [34]. The size
of present populations makes the species susceptible to the loss
of genetic polymorphisms, which could be reduced by the effects of
random genetic drift and inbreeding.
