Where I was froming come is that I was always told to use 0.004 hectare
to represent the amount of ground area in a prism sweep as a rough and
dirty
number for a 2 BAF (metric) prism. I know that it will vary based on stem
diameters but I was wondering what the same rough and dirty number was for
a
10 BAF Imperial.
Cheers

I'm not quite sure what you're asking. Acceptable sample size (ie number
of
plots required to achieve a required Standard Error) is not directly
related to the prism size. Ideally, you wouldn't choose a prism until
you
saw the size and number of stems in a stand.
And as for ground area represented by a prism, I really don't understand
the question. The plot radius of each tree is a function of the BAF and
the tree's diameter.
So, I guess I'm no help, I just felt like babbling

Hello
I am doing a point-in-polygon GIS analysis and need to know what would
be
the acceptable sample size (ground area) represented by a 10 BAF prism
(10
ft2 per acre) at each point.
