Windsor Great Park walk: types of oak tree: there are more than I thought!

As I had planned I did venture into Windsor Great Park, and it was a bleak experience over half term - a very chilly day. Eventually I did come across something interesting - the Queen's collection of oak trees, given to her by the countries of the Commonwealth on the occasion of her Coronation or marriage - can't remember which, and I can't find any reference to this collection online. There are of course, more countries in the Commonwealth than there are types of oak tree. (- Post script - this isn't' true. There are more than 600 types of oak tree in the world! But some of them come from Mexico, China and South America and perhaps they don't grow in a temperate climate.) So you can see below that there is a variety of trees but some of them are duplicated 2 or 3 times by different donors.

 Here is a sample of the labels. In the summer and autumn it will be fun to see all the different leaves.

It is a mast year

which means that the oak trees have produced acorns. They land on our roof all night. However, although I am glad for the tree, which I feared had become sterile, I miss the squirrels. They used to go quite mad when there were acorns. All the squirrels have vanished from this corner of the cul-de-sacs. I have looked for news about this and not found any.

I live behind a great oak tree

and once again it is barren. I have lived here for 10 years and only known it to have a "mast year" once, with acorns everywhere underfoot and acorns bouncing off the car every few minutes. This year many of the trees are covered in fruit (the limes are messy and the sycamores are going to be a real trial with their random seeding) and the oak tree is doing nothing. I wonder why? Apparently this irregular fruiting pattern is a mystery to science and nothing to do with weather patterns or environmental factors (according to an American website) but if anyone knows better I hope they will tell me.
