Survival of delivered trees against handover (percent)
Definition
Trees delivered with monitoring observed alive at a declared horizon from T1, divided by the trees the recipient acknowledged at handover in the stand’s consignment lines, as a percentage. A tree not observed counts against survival: the frame is the acknowledged consignment. Horizons run from the handover date (ADR-0031).
purpose
To report how many handed-over trees still live at each horizon, against what the household received rather than what the visit happened to see.
rationale
A delivered tree has no planting-day position to search; counting the acknowledged trees as the frame keeps a tree that was given away or never planted from leaving the denominator.

- Survival family: The outcome indicators computed from one monitoring visit’s tree observations under NCGS-M001: trees alive at horizon, survival rate, trees by condition class, establishment rate; and for trees delivered with monitoring, planting uptake at T0+ and survival against the trees acknowledged at handover (ADR-0031).
