Custodian STS-C-00001 · Nkhensani Dhlamini · Hoxane TA · Phase 3.
Each pin is a row in the database.
A Tree Custodian is the legal and economic counter-party for the trees on a single parcel. The custodian owns the land or holds it under customary right, plants the trees, keeps them alive, and earns from their measured carbon and from the marula they fruit. The obligation runs 40 years. Payment is performance-based — against surviving, measured trees, not promises.
This page is the template. The Marula Block is the first instance. Every custodian who follows — across Hoxane, Amashangana, Jongilanga, Mathibela, Mnisi, and Moletele — gets a page like this one, on the same dataset, with the same map and the same provenance chain. The site is the public face of the registry. Nothing on it that isn't in the registry.
Phase 1 of Save the Sand runs on a census-based protocol: every tree on every parcel is registered as a discrete record, not inferred from sample plots. At planting (t=0) we capture species, planting guild, height, basal diameter, jittered GPS, and the custodian — each tree carrying its own ID in the form STS-YYYYMMDD-####. Saplings are too short for diameter-at-breast-height (DBH); DBH joins the record at first census, once a tree reaches 1.3 m.
Trees are planted in guilds — Large, Medium, Small — chosen so each parcel becomes a structurally diverse food-and-canopy system rather than a monoculture. Nkhensani's 126 trees split across the three guilds and 11 species. Guild is a field on every tree record and drives the allometric equation applied at carbon-stock calculation.
Data integrity is enforced by triangulation — three independent channels observe the same tree, and their agreement is the audit signal. The composite indicator is named SOP-MRV-920a "Triangulation Delta". Where the channels disagree, the divergence is measurable, trended, and auditable. The whole stack is built against VM0047 v1.1 + CCB v3.1.
Phase 1 supply for Nkhensani's pilot moved through two routes — each documented end-to-end so every tree on the map above can name the nursery that raised it and the donor that paid for it.
