The genus Quercus includes around 450 species distributed across the Temperate and Subtropical Zones of the Northern Hemisphere.  Many species are practically unobtainable in commercial nurseries, and for that reason it is very difficult to create new collections that include species other than the more ordinary ones.

Valonia Oak Restoration Project, Castlemaine, Victoria

A restoration project that will be of interest to IOS members is taking place in the Australian state of Victoria. A plantation of Valonia oak (Quercus ithaburensis subsp. macrolepis) at Castlemaine, Victoria, dating to the late 19th century, has suffered deterioration due to a decade of drought, and only three of the original 14 trees are still alive. Acorns are being collected from the surviving trees with a view to producing new trees to replant and restore the historic stand.
