Here I’ll show 3 stand level info. I chose 3 young doug-fir stands. I will have a SVS stand “picture” as well as boardfoot volumes (hardwood and softwood—this may seem silly but the program graphs both and I am just doing a screen capture), cubic foot volumes, softwood QMD, total basal area per acre and stand density index.
Stand 1 -- is FIA county 41, plot 36, condition class 1. It is a young stand with 405 doug-fir per acre. The Bruce site index is 160. This stand is grown in the SMC ORGANON and PN FVS.
Stand 2 -- is FIA county 39, plot 32, condition class 1. It is a young stand with 395 doug-fir per acre. The Bruce site index is 131 and Cochran site index is 180. This stand is grown in the SMC ORGANON and WC FVS.
Stand 3 -- is FIA county 33, plot 83, condition class 1. It is a young stand with 490 doug-fir per acre. The HannScrivani site index is 86 and King site index is 85. This stand is grown in the SWO ORGANON and NC FVS.
The program scales the graphs so this one has a different scale. Sorry.
I checked the keyword file and this guy had a BAMAX of 381. In the output file there was a note that the forest max of 850 had been exceeded and so 850 was the SDI used for Doug-fir
Super Bonus Slide - I had it so here it is. These are the SDI and Basal area per acre values over time for the control plots at several LOGS installations. Does SDI peak and stay there or does it come down? Does BA/acre keep going up? Who knows, but look at all the pretty colors.
