Geneflow in native tree species

One of the most important processes in maintaining genetic diversity is geneflow. Tree populations tend to maintain high levels of genetic diversity and this is partly due to long distance geneflow. Using microsatellite markers, we have examined pollen flow in species such as oak and cherry and shown that a considerable proportion of the seed is the product of pollen originating from outside the stand (Cottrell et al. 2009; Gerber et al. 2014).
