Standing live and dead tree status

ID
Tree_Status_ID
Description
1
Live
Live standing tree
2
Status 1
Status 1: Small branches and twigs are retained; resembles a live tree except for absence of leaves. Typically the allometric equation for a live tree and then subtracting for leaf biomass is the most accurate to determine biomass of Status 1 dead trees.
3
Status 2
Status 2: No twigs or small branches; may have lost a portion of large branches.
4
Status 3
Status 3: Few or no branches, standing stem only; may be broken-topped.
