Tree individuals by condition class at horizon (count)
Definition
The number of tree individuals observed in each condition class (thriving, some stress, serious stress, pest damage, dead) at a declared horizon. The condition axis is the tree-conditions scheme; the counts over all classes equal the trees observed.
purpose
To show not only whether trees live but how well, so that stress is visible before it becomes mortality and stewardship can respond.
rationale
The KIA-Adapt follow-up scored the same five classes; keeping them lets 2024 and 2026 be read together and gives establishment its thriving class.
Classification

Collections
- 2026 core indicator set: The fifteen indicators a 2026 project under the standard reports: the site preconditions and assessments, delivery and planting, education and care, and the survival family to T2. Every member is approved and served by an approved methodology whose records exist in the standard; the monthly and final reports are queries over approved claims at these indicators. Module indicators sit outside it.
- 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).
Methodologies that serve it
- NCGS-M001 — Census count of tree state at a declared horizon
- NCGS-M002 — Stratified-sample estimate of tree state at a declared horizon
