SC: Forestry Commission have lots and lots of information. Search on FC and
windthrow. And Dr, Barry Gardiner is a lead researcher.
SC As an aside, going back to some undergraduate archaeology of the British
Isles, I think chert is the whitish layer found on the outside of roundish
flint nodules. Stone age man gathered these nodules along beaches and river
beds to make into flint tools. The nodules also became trade objects becuase
they werer not found everywhere.

Subject: Risk of windthrow
Can anyone (in the south-west I guess) offer any advice/information
regarding the properties of a certain soil that I have come across in
Dorset? It has been described to me as "greensand with chert". Chert being a
rock type present not unlike flint is in soils in my neck of the woods (East
Sussex).
I am particularly interested in its behaviour on steeply sloping woodland
sites. It seems pretty unstable and windthrow quite a common occurrence.
