Variant(s): All
Topic(s): The Fire and Fuels Extension (FFE) was recently updated to report output on cycle boundaries. The FFE keywords controlling output reporting were updated in this software release to better represent the new reporting system. Problems were corrected in the litter and duff consumption rates, and in the canopy fuels profile database output format. The FVS-WRENSS water yield post-processor was updated.


Bulletin: 729
Model(s): FVS
Variant(s): All
Topic(s): Increased the number of Species Groups that may be used in a simulation to 30 Groups using the SPGROUP keyword


Bulletin: 729
Model(s): FVS
Variant(s): All
Topic(s): The Fire and Fuels Extension (FFE) was restructured to run on cycles rather than annually, the white pine blister rust extension was linked to appropriate variants, problems with the SQLin keyword and with the height to merchantable top estimates in the database tables were corrected, board foot volume methods in Region 9 where updated, the default volume equation for ponderosa pine in Region 3 was changed, a problem in calculating merchantable volumes for 32 foot logs was corrected in the Southeast Alaska and Coastal British Columbia variant, FFE table headers were edited to clarify that the tables are based on stockable area, Potential Vegetation codes with reference number 653 were added to the East Cascades variant, and a correction was made to the ADDTREES keyword.


Bulletin: 728
Model(s): FVS
Variant(s): All
Topic(s): Corrections were made to the THINSDI, THINCC, THINRDEN, THINPT, THINRDSL and PRUNE keywords.

  4. Dwarf mistletoe table (all western variants)
  5. Small tree height (CS and LS)
  6. Board foot volumes (CS, LS, and NE)
  7. Tripling diameter estimates (all variants)
  8. Bark ratio calculations (IE)
  9. Hemlock volume equations (PN and WC)
  10. File header (CR)
