Post-transplant survival compliance: proving the moved trees are alive.

For the period stated in the permission, which varies between authorities and is commonly measured in years rather than months. Where a deposit has been taken against survival, the monitoring period usually runs until that deposit is considered for release.

Tree by tree against the numbered register: whether the tree is alive, its crown condition and leaf flush, new growth, structural stability and anchoring, and any pest or disease signs. Photographs from fixed positions accompany the record so that condition can be compared across visits.

It should be reported, not omitted. Authorities generally expect the loss to be made good, commonly by planting replacement trees to a specified ratio: and a declared, remediated loss is treated very differently from one discovered at inspection. The remedial action becomes part of the compliance record.

The permission holder, which in practice means the project owner, whether the work is done in-house or by a contracted agency. Responsibility does not transfer with the crane; it runs for the whole survival period, and should be written into the maintenance contract explicitly.

Regular irrigation calibrated to the season and the reduced root system, checking and adjustment of anchoring and guying, mulch maintenance, watch for pests and fungal infection on cut surfaces, and staged crown management as the tree re-establishes. The first two summers after the move are the critical period.

Where the authority has taken a security deposit against transplantation or compensatory plantation, release is considered against demonstrated survival at the end of the period. A continuous, dated, tree-wise record is what supports that claim; an undocumented plantation that is in fact healthy is still difficult to get released.
