Growth Model Users Group

This report outlines the current status of the Region 6 (R6) Growth Model Users Group, highlighting key data gaps and ongoing projects. It provides an analysis of the number of CVS plots by FVS variant, including a total of 11,433 plots and a breakdown of tree records in East and West Cascades variants. The document also discusses site index work and the variance in modeling major tree species and plant associations. Special attention is given to contrasting East Cascades and West Cascades variants, including the number of plots in each sample.

Presentation Transcript

  1. FVS Information Gaps Ongoing Work from Region 6 Growth Model Users Group January 11, 2007 Carol Apple, Melinda Moeur, Jim Alegria

  2. Number of R6 CVS Plots by FVS Variant (11,433 total)

  3. Number of Tree Records in R6 CVS data by FVS Variant

  4. Number of Growth Sample Trees in East Cascades and West Cascades Variants (R6 CVS data)

  5. FVS Variant Map (R6, R5, FMSC)

  6. Site Index Work (Fred Hall)

  7. Not all major tree species have models in each variant Cell value = tpa in the CVS sample

  8. Tree species: contrast East Cascades and West Cascades variants Cell value = tpa in the CVS sample

  9. Not all major Plant Associations have models in each variant (WC example) Cell value = number of plots in the CVS sample

  10. Plant Associations : examples for West Cascades variant Cell value = number of plots in the CVS sample
