I am an MS student at the University of Washington College of Forest
Resources.  I am currently developing a topic for my thesis - I would like
to take a look at spatial autocorrelation of individual tree
characteristics (such as dbh, crown class, age) within young forest stands
in the Pacfic Northwest.  To begin I'd like to see which, if any, of these
characteristics are spatially autocorrelated.  I would also like to
compare spatial distributions of dbh and age to see whether spatial
position within the stand can explain some of the wide variation in the
dbh vs. age relationships.  I suspect that variations in the length of
the stand initiation period may have a lasting influence on the spatial
distribution of these tree characteristics.

In order to accomplish this, I need to put together a data set of mapped
stands (xy coordinates along with dbh, age, crown class, and hopefully
other measures for the individual trees).  I would like to focus on either
pure (or nearly so) stands of Douglas-fir or Western Hemlock in the
coastal region of the Pacific Northwest, ranging in age from 20-60 years. 
I want to stick with younger, single-species stands to avoid the
confounding effects of multiple species and stochastic mortality in older
stands.  I have no direct finding for my thesis project (I'm funded as a
teaching assistant) so I am very limited in the amount of time and effort
I can expend mapping stands myself.  Therefore, if anybody out there has
available stand data of this type and is interested in having this type of
analysis done, I'd love to hear from you.  Also, if anybody out there is
involved or interested in similar research, I'd be interested in your
comments.  You can reply to me directly via email. 

Thanks!
Mike
