The araeters are segregated by seces wthn the lot. Each seces s segregated by daage code for daage colatons. Refer to Aendx 1 for the lst of seces used. Count lots are ncluded n the lot suary. Only nclude trees n a lot that eet the erchantablty requreents fro card tye B. Plots are sorted wthn Tye, Bloc, and Str. Stes are trees wth Tree Class coded 1,, 3, 5, 7, 8, or 9.
