wood turners are the best source of information on the subject of bog oak,
we love the stuff! poor man's ebony,  Though I have to confess Ive just
managed to secore a disgustingly expensive haul of the latter!

My understanding of the succession to bogs as climax communities is that
it tends to occur in the peri-arctic zones; there was a fascinating
presentation about this at an Arb Conference some years ago - Nottingham?
Of Cambridge? By an American researcher. The bog oak found in the UK
probably mightd date from the advancement of sphagnum moss bogs in the last
glacial? Though I don’t know if this is the case. Examples include the
somerset levels and East Anglian fens; has anyone done any C14 dating on
bog oak from these sources - it still turns up regularly?

I am not an ecologist, I know nothing of Klinger's authority and I haven't
read Klinger's papers, but a quick look at one of his papers' summaries
shows lots of clauses expressing uncertainty (excerpts below, the
highlights are mine). I am still to be convinced that all forests will tend
towards peat-bogs. Call me old-fashioned but I would need more scientific
consensus and more scientific evidence.

"This paper presents a model of a possible Gaian mechanism related to
landscape-level successional changes during a glacial-interglacial cycle.
The model is based on the view that terrestrial successions converge toward
bogs, rather than toward old-growth forest, and that bogs represent
structurally and compositionally stable (climax) communities. T he model
also assumes , as in classical successional theory, that during the course
of succession the biota modifies the environment, both the soil and the
atmosphere, to favor the progression of succession toward the climax
state."
