Catalog of Oaks at Grigadale Arboretum Published Online

Quercus rugosa in Grigadale Arboretum, 8.3 m tall, planted out in 1998.

Grigadale Arboretum in Argentina has taken a first step in making the species list of its oaks available online. The website currently lists all existing established trees planted between 1994 and 2007 by the collection's founder Duncan Cameron, including accession number and date, measurements and photographs, and basic info about the taxon (section, distribution). In time I hope to add source information and a description of each taxon as well as information on how the trees adapt to local conditions. I will also be expanding the list to include the oaks we have planted in recent years. The website is in both English and Spanish, and I hope the Spanish version particularly will be of use to local Quercus enthusiasts, as most information available online is in English. This is a work in progress so all feedback is welcome, particularly regarding IDs, as I have already found that labels were incorrectly placed, some trees grew from rootstock after the grafted scion died, and others may have been provided under a wrong name.
