Genetic diversity and (micro)geographical isolation of Dutch Juniperus communis populations

During the past centuries habitats of the dioecious species Juniperus communis L. (juniper) became fragmented or disappeared. Moreover, rejuvenation in Dutch J. communis populations is minimal. As a result, J. communis has become an endangered species. A study was started into the genetic diversity and relationships of the surviving J. communis populations. The results will serve as a basis for programs to protect and restore Juniperus communis populations in the Netherlands, and for future international projects.
