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 Podebrady, enthusiastic and dynamic IOS member Dusan Placek is sponsoring a "Birthday Banquet" for participants.
Oak Open Days in Congrove and Westonbirt
The first European event of the year will be in the UK, where turnout has been so encouraging that we are offering a two-day event (but members may opt to attend either day on its own). On Sunday, July 6 Christine Battle has kindly offered to open to the IOS her collection of rare oaks and other unusual trees at Congrove Arboretum, commencing with a buffet lunch at 12:30; the following day, Monday, July 7, we make an all-day visit to the well-known arboretum at Westonbirt, with its many splendid mature trees.
Several IOS members will already know the ‘hidden gem’ of Congrove, but here is a little more information from Christine for those who have not visited before:
Ben and Christine Battle began planting trees shortly after they moved from London to Congrove about 16 years ago. The original plan was simply to replace the trees lost from a Victorian pinetum over the intervening decades since WWII, but this soon became a passion for collecting which has resulted in about 2,500 new specimen trees being planted in the last decade. Quercus are a particular favorite, and Congrove is now home to around 200 species. They do particularly well in the benign microclimate, which consists of a south-facing valley side. Long hours of sunshine, much (sometimes too much!) soft West Country rain and good drainage combined with shelterbelts of mature native trees provide warmth, shelter and nourishment - an ideal habitat for oaks. Magnolias also flourish in these conditions, as do some of the more tender species of Pinus (e.g., Pinus maximartinezii) and other conifers such as Araucaria. In all, some 25 to 30 acres of the 65-acre property are now planted with specimen trees or native woodland shelterbelts. You can read an interview with Christine about her oak collection here.

The magnificent collection at Westonbirt was first started by the Holford family and includes many mature oaks.
Below is a short word from botanist Dan Crowley, who will be hosting the Oak Open Day:
"We currently list 247 taxa - we have some that are currently listed only to genus level, but some of these are native or Q. cerris or possibly hybrids between the two! Those of note include fine mature examples of Q. robur, Q. canariensis, Q. ilex, Q. macranthera and Q. frainetto, as well as some of the more common North American species. Concentrated diversity can be found in part of Silk Wood, where earlier management initiated the planting of a number of 'collections' with Quercus being one of these. Whilst planting in this area is no longer restricted to oaks, a significant number are found here. Both young and mature examples of various species can also be found throughout the site. Plantings in recent years include examples of Q. variabilis, Q. gravesii, Q. rysophylla 'Maya' and Quercus mongolica ssp. crispula from a Westonbirt-led trip to Japan, to name a few! As mentioned, there are inevitable 'queries' among representatives of the genus, which no doubt shall emerge throughout the course of the day!"
