BS5837 and stem diameter

Hi All

 

I have read a small amount of the summaries relating to the above. Apologies
if this point has ben made.

 

I once asked the question of an authority Mr R Nicholson why 1.5m from
ground level which is called stem diameter in 5837 not dbh. Dbh has never
appeared in 5837 and it would be incorrect to use it any work related to
5837 in my opinion.

 

Anyway the answer is - 1.5m as this is the height at which trees are
measured when determining stem diameter for thinning operations in relation
to designated Conservation Areas. That was taken on as the height for 5837
work.

 

Hope that helps clear the issue up.
