The question
A forestry company wanted to restore drained peat and needed a baseline before any ditch was blocked.
Approach
Level loggers were set in a grid across the bog. Surface height was re-levelled twice a year from benchmarks on mineral ground.
What we found
Drained strips sank measurably while untouched hummocks held. The baseline gave the restoration team a before and after they could both trust.
Limits
Peat swells and shrinks with the seasons. Two readings a year cannot separate that from true subsidence.
