You may select a diameter range over which
you would like to make the summaries. This will supercede any decision
you may have made above for size class. The smallest diameter included
in the data is 2 cm and there are no trees over 120 cm dbh. (Note
that all trees 2.0 to 2.4 and 10.0 to 10.4 will be doubled, and all
trees 9.5 to 9.9 will be excluded. See explanation .
We recommend using either integers (except 10) or a midpoint range
(i.e. X.5 to X.4), unless you have read all the notes and understand
exactly what the program returns.)Enter lower diameter (in cm):
Enter upper diameter (in cm):

3. OR, enter a lower and upper elevation limit (in
meters). The elevation range for Watershed
6 is 550 to 792 m. (Please left justify and leave one space between
the numbers, e.g. 600 700):
4. OR, enter a single plot. Plots in Watershed
6 are numbered 1 to 208:
5. OR, enter the numbers of the first and last plots
in a sequence (please left justify and leave one space between
the numbers, e.g. 23 48):
Note: If you want summaries for the standard
"thirds" (or "sub-areas") of Watershed 6 as published
in several papers, use 1 to 86 for the upper third, 87 to 158 for
the middle third, and 159 to 208 for the lower third.
You may select a particular species for which
you would like to see a diameter distribution by 1 cm diameter classes.
If a species is not chosen, the program will make the summary graph
for all species combined.
