Obviously it was not meant in the literal sense, different ecologies,
different outcomes. That said, there is no arguments regards the
successional nature of ALL ecosystems, unless of course there applies some
basic environmental conditions that perpetuate the cycle, I.e gums burning
and seed regenerating. Man coppicing for a thousand years or more,
maintaining an ecological balance of succession.

I certainly did not mean for my comments on this matter to be taken so
dogmatic as to apply universally, to do so would be ridiculous, climate,
environmental circumstances etc are all too variable to have the same
outcomes.

Humus building is acidifying, and acidified soils favour pathogenesis, the
driving force in ecology, it is simple biology and not so radical as to be
akin to declaring the world is flat.

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."
