Stem Analysis

XLSTEM  
XLSTEM is a stem analysis module offered as an option to WinDENDRO. It is a set of macros that runs in Microsoft Excel (Excel not included).

XLSTEM calculates the following information from ring width data produced by WinDENDRO:

  • Mean radius (quadratic method), diameter and area per disk (available cumulatively or incrementally).
  • Tree height and volume as a function of age or year (available cumulatively or incrementally).
  • Basal and summary information about the tree.

Three height interpolation methods are provided:

  • Linear
  • Carmean
  • Newberry

Calculations can be done interactively on selected trees or in batch.

All data can be displayed graphically.
