If this is a permanent monitoring plot, percentage of plants of the species observed in this plot, in either this observation or in previous ones, that were dead. Null if this is not a permanent monitoring plot in the current observation.
cumulative_dead int4 10 0

If this is a permanent monitoring plot, total number of dead plants observed in all observations including the current one.
permanent_live int4 10 0

If this is a permanent monitoring plot, the number of live and existing plants observed. 0 otherwise.
survival_rate int4 10 √ null

If this is a permanent monitoring plot, percentage of plants of the species observed in this plot, in either this observation or in previous ones, that have survived since the t0 point. Null if this is not a permanent monitoring plot in the current observation.
