Thanks so much Doug, glad you're still reading, there is a lot of info on the site. I have also done a little more on - https://hautdesertpurlieu.wordpress.com/, some duplicate, some new. Dr Ad Putter of Bristol university, said he could not disagree on the description of hautdesert being a high forest. I know of only one high forest that was next to what is described as, "nobut an old cave, Or a crevice of an old crag ". Bertilak was surely of the high forest next to Ludchurch.
