Tree individual
One physical tree, the primary unit of observation (ADR-0002). A urn:uuid: node created when the tree first becomes distinguishable (ADR-0003), here at planting. Points at the most specific species or cultivar concept known.
Kind of: Thing
Properties
| Property | Required | Repeatable | Value | Message |
|---|---|---|---|---|
| at position | no | no | Planting position | A tree individual stands at at most one planting position; a tree planted by the implementing partner stands at exactly one. |
| compost or manure mixed into the hole | no | no | boolean |
|
| container size (litres) | no | no | decimal |
A tree individual records the container size it was planted from. |
| fate of an unplanted tree | no | no | NCGS Unplanted Tree Fates: Still in its nursery bag, Given away, Died before planting, Lost or stolen | |
| from consignment | no | no | IRI |
|
| guarded at planting | no | no | boolean |
|
| has evidence | no | yes | Evidence item | A tree individual’s photographs are evidence items. |
| hole typology | no | no | NCGS Hole Typologies: Raised border or ridge, Flat, no border, Basin below ground level, Mound above ground level | |
| mulch applied at planting | no | no | boolean |
|
| planted at the same depth as in the nursery bag | no | no | boolean |
|
| planting date | no | no | date |
A tree individual has at most one planting date, the anchor of its horizons; a delivered-only tree anchors on its consignment’s delivery date. |
| rootstock | no | no | string |
|
| species or cultivar | yes | no | Concept | A tree individual names exactly one species or cultivar from the register. There is no free-text other. |
| staked at planting | no | no | boolean |
|
| stem painted white | no | no | boolean |
|
| steward or owner | yes | no | Agent role | A tree individual has exactly one steward or owner, as an agent IRI and role (ADR-0007). |
| stratum | yes | no | NCGS Strata: Delivered only, Delivered with monitoring, Planted without monitoring, Planted with monitoring | A tree individual is in exactly one stratum: delivered only, delivered with monitoring, planted without monitoring or planted with monitoring (ADR-0003, ADR-0031). |
| tag number | no | no | string |
|
| tree planted | no | no | boolean |
|
| vegetation type | no | no | Concept | A tree may repeat the vegetation type at its position (a form convenience that drives the species picker). |
Rules
- A delivered tree, monitored or not, comes from a consignment: it must reference the consignment it was handed over in (ADR-0003, ADR-0031).
- A delivered tree, monitored or not, was not planted by the implementing partner: no planting record by a fieldworker or supervisor may name it; a planting record by its owner or steward is valid history and leaves it delivered (ADR-0003, ADR-0031).
- A planted tree’s stratum follows its site’s designation: planted with monitoring at a site designated planted with monitoring, planted without monitoring at any other site, and no tree is planted by the implementing partner at a site designated delivered only or delivered with monitoring (ADR-0029, ADR-0031).
- A species listed under NEMBA category 1a or 1b may never be planted, whatever its approval status (ADR-0009).
- A thorny or poisonous species is not planted within 10 m of where children play or walk, by the site’s latest assessment that gives the distance (#99).
- A tree comes only from a consignment that was handed over, never from a failed delivery attempt.
- A tree from a consignment must be a species or cultivar the consignment carried: a delivered mango cannot become a planted olive (ADR-0003).
- A tree in a planted stratum carries the planting-day record: container size, planting date, position, hole typology, compost, depth, mulch, stem paint and a photograph.
- A tree in a planted stratum must be named by a planting record whose observer is a fieldworker or supervisor of the implementing partner (ADR-0003).
- A tree individual exists only once it is distinguishable: it carries a tag, or a planting record names it, or an observation is made of it (ADR-0003).
- A tree recorded as not planted has no planting date or planting practice; one recorded as planted has no unplanted fate.
- A tree with a planting date was planted: it has no unplanted fate.
- A tree’s tag must be one its consignment issued, where the consignment issued tags at all (ADR-0002: the tag is the bearer of the identity, and it was handed over with the trees).
- A vegetation type stated on a tree must be the one the site’s latest assessment observed; the site state is the fact of record.
- A withdrawn species or cultivar may not be planted.
- Instance data must not use the standard’s namespace https://nova.org.za/ncgs/ (ADR-0002: instances are urn:uuid: IRIs).
- The species or cultivar must be a concept in the NCGS species scheme (no free-text other).
- The steward or owner role on a tree must be steward or owner.
