The Norwegian Defence Construction Service is carrying out a large scale
experiment of noise propagation from explosions in a forest area. From the
litterature it is known that the vertical structure of forest stands is of
importance  for the propagation. Measures of vertical structure at the stand
level such as percentage of dominated trees, percentage of self purned stems
in relation to mean height, and density of bush understorey have been used.
However, maybe there are measures of vertical structure/distibution used
within other fields of research that may be appiled.  Do you know of any
such measures (references)? They should be easy to measure in an objective
way on sample plots, along transects etc., and it should be possible to
produce estimates at the stand level from several plots/transects/etc.
within each stand. The sampling aspect must therefore be considered.
