Developing and promoting silvicultural tools and techniques for the restoration and renewal of western
model.• Utilizes 80% of data set.• Strong autocorrelation.
• Increment model is less autocorrelated.
• Utilizes 100% of data set.• Weak fit without good data
describing environmental and morphological parameters.
How useful is a diameter based model predicting a fixed growth period?
While not biologically valid, will it perform across a local landscape?
For the increment model – What could be done to account for more of the variability in the model?
Will increased site and stand factors limit the portability of this model?
Is the dataset powerful but not useful or is it a diamond in the rough?
What would you do with this data?
