Terra
Terra includes plants, seeds, soils, stones, living collections, material examined through ecological care or natural history. Some examples grow and decay during custody. Others change slowly while people attribute geological or personal histories.
A cutting requires watering, suitable conditions, responsibility during absences. Staff record its care and changes alongside contributed accounts. A propagated cutting can become another material instance with a relation to the earlier plant. The transfer involves biological continuity as well as a new custodial interval.
Returning participants may notice changes across visits or exchange care notes. Staff need a practical plan for pests, decline, propagation, return. A plant's condition can reflect several circumstances, so an attribution of care requires context. Parts, material identity, traveling custody explain the recordkeeping questions.
