We moved our website to A2 Hosting's data center in Michigan on Friday. The migration went very well. Unfortunately a technical incoident, issues with A2's DNS Services, prevented us to go live.

I have recently been asked to write or update the oak entries for Trees and Shrubs Online. This is a project to create a truly modern reference to temperate trees and shrubs. Currently there are articles for some 730 genera and 4,500 species, with each species article describing subspecies, forms and cultivars.

I enjoy finding giant trees, and always keep an eye open and a tape measure handy. Some of my finds are only giants in the sense that they are large for their species, such as my National Champion Prunus hortulana (30 ft tall). When my family and I got the chance to traipse around New Mexico in the fall of 2016, acorns and photos were not the only things on my mind. I also brought my tape measure.

Abundant rain in southwest France in the early part of this year has fostered a bumper seed crop at Arboretum de la Bergerette, some (such as Quercus emoryi) already ripe: thus my thoughts turn once again to the seed exchange forum I mooted, which is at present under construction – many thanks to those of you who have already contacted me on the subject, confirming that the idea is worth pursuing.

I decided to develop a map which would allow the registration of all the oak trees in Israel.

It is written in the entry for Quercus chrysolepis at www.efloras.org that “Quercus chrysolepis is one of the most variable North American oaks.” If this comment relates primarily to the mature plant and its characters, it’s also true of the youngest leaves in development.

Those coming to the IOS Conference in Davis, CA in October will see one of the best oak collections in the U.S. We invite you to include in your travel plans a visit to a different world, the Southeastern U.S.!

This year I harvested acorns in Grigadale Arboretum rather late in the season (April), at a stage when most species had dropped them. As trees are planted quite close together, in some cases I had to distinguish acorns based on their shape in order to collect from a particular tree rather than its neighbor. When it came to Quercus ×kewensis, there was a mass of acorns on the ground, many from several neighboring Q. cerris. I found that I could pick out the Q. ×kewensis because of their odd shape.

I conducted studies under the supervision of Dr. Ranbeer S. Rawal in the laboratory and an experimental nursery to understand seed germination behavior in relation to desiccation for different drying periods in Quercus floribunda. Based on the results we recommend that the seeds of Q. floribunda should be sown within 7 days, when the seed moisture content remains above the critical level of 34%.

Last April I briefly visited Canberra, the capital of Australia. I was able to take a day off to look at trees and spent most of it admiring the impressive collections of Australian native flora at the Australian National Botanic Gardens. This was my first trip to Australia and I had been looking forward to the diversity of its endemic trees. But Canberra also offered a quite unexpected treat: several Californian oaks used in well-maintained plantings along residential streets.
