Dear Colleagues,
Can anyone tell me where it could be found SCHEMES (positions of
trees and their crown projections) of the UNIFORM PLANTED TREE-STANDS
with nearly the SAME age and species composition and different
initial density for analysis as something like the following abstract
(full text of the communication could be got from me, 15kB)? I would
be glad to hear anything about (including corrections of English).
Thanks

Ranking Similar Forest Plots by the Intensity of Competition through
an Analysis of Their Contour Planes

Abstract
The planted uniform tree-stands displaying similar mean
characteristics can be ranked according to the course of competition.
The data showed a significant correlation between of parameters of
neighboring trees at certain stages of competition. This correlation
disappears upon the tree-stands thinning at subsequent stages of
competition but can be then restored. So the competition process is
the non-monotonous one in such tree-stands. The coefficients of
correlation between the crown projection areas and the areas of the
corresponding Voronoi's polygons can be regarded as markers of the
peak of the competition. In natural even-aged tree-stands the
"competition age" is the variable changing in space. This could
explain the failure of attempts to find a significant correlation
between parameters of trees and local characteristics of the spatial
structure.
