Not much botany this week

But a bracing walk up to Castell Dinas - one of the many places nearby I hadn't got round to yet. I must say this has the best view / achievement etc to effort ratio of any climb around here:

This was part of a U3A "Lost Farms and Villages" walk. We encountered an unusually gnarled and nearly dead Ash - but nothing to do with the latest threat to the tree I think - just a very exposed location. Why did I fail to photograph it though ? 

The Ash disease threat is, of course, very worrying - so at least from the species' point of view it is heartening to read that there are reports of resistant trees emerging in Lithuania. But it looks increasingly likely that the whole of Europe will face a lack of mature Ash trees for many of the next few decades.
