Site Index Work (Fred Hall)

Not all major tree species have models in each variant

Cell value = tpa in the CVS sample

Tree species: contrast

East Cascades and

West Cascades variants

Cell value = tpa in the CVS sample

Not all major Plant Associations have models in each variant

(WC example)

Cell value = number of plots in the CVS sample

Plant Associations : examples for

West Cascades variant

Cell value = number of plots in the CVS sample
