Where the trees are, and how they are doing.
A site's point is published to two decimals of a degree, roughly a kilometre: enough to say where the trees grow, too coarse to walk to one. The positions of single trees go only to the person who takes a monitoring visit, for that visit, and are not published. Photographs are checked for hidden location data before they are published.
Survival is each site's standing trees over the trees checked, from every batch's latest check. Damaged trees are alive; a tree not found counts as lost. Each batch is checked for three years after planting (Section 9.5).
This page reads sites/index.json, built from
monitoring.json and checked by the standard's own parser,
which refuses a tree coordinate. Batch by batch: published records.
