Barking up the Right Trees

A young and vigorously growing Quercus ‘Maya’ that we planted in 2007 showed a minor crack at the base of the trunk after the winter of 2011-2012...

Two weeks exploring pine-oak forests and botanic gardens around Mexico City, Puebla, Oaxaca, and Monterrey. Pre tour to see archeological site. Post tour to see 12,000-ft elevation oak forest at Nevado de Colima, to Morelia, and to Tlalpujahua.

Quercus humboldtii in Bogotá

Quercus humboldtii in Bogotá

I spent a weekend in Bogotá in October 2017 and made it my mission to find Quercus humboldtii. I had had the species in my sights for a long time: it is the only oak native to South America, and so the closest non-cultivated oak to my residence in Montevideo, Uruguay (a mere 4,700 km as the crow flies—though it might take a relay of crows to make the trip!).

Bruce Bacon (1940 - 2017)

I first met Bruce Bacon in 1984, and since then and through his Garden Farme, I learned about soils, fruits, salads, vegetables, organics, permaculture, sustainable ag, arbor care, tree propagation, prairie restoration, forest management, wetland preservation, weeding, mulching, woodchipping, landscaping, woodstove heating, bee keeping, domestic geese, sandhill cranes, the I-Ching, cooperatives, collaboratives, allies, CSA's, resistance, revolution, kitchen table philosophy... and the list goes on.

The Michael Heathcoat Amory Award: Call for Applications

The International Oak Society invites individuals with research projects contributing to advancing our knowledge about, or appreciation of, oaks or their conservation to submit applications for the Michael Heathcoat Amory Award.

The IOS has its 25th anniversary in 2017, and a superb way to celebrate it will be to get yourself to the Czech Republic in July where, during Oak Open Days based at his arboretum near Poděbrady, enthusiastic and dynamic IOS member Dušan Plaček is sponsoring a "Birthday Banquet" for participants at Poděbrady Castle.

Request for Acorns for Oak Wilt Study

We have received a request from The Morton Arboretum for acorns of northern pin oak (Quercus ellipsoidalis), red oak (Q. rubra), and bur oak (Q. macrocarpa) to support a study on oak wilt.
