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."
