Addressing Information Gaps in Regional Growth Model User Data for Region 6

Collaborative efforts by Carol Apple, Melinda Moeur, and Jim Alegria on enhancing Region 6 Growth Model user data. Analysis includes number of CVS plots, tree records, and growth sample trees, as well as FVS Variant map and site index work by Fred Hall. Exploration of discrepancies in tree species and Plant Associations models across East Cascades and West Cascades variants. Focus on improving accuracy and completeness in user data.

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
