Wetland restoration baseline & hydrology mapping

LiDAR-derived micro-topography and multispectral vegetation indices across 340 ha of drained wetland to design re-wetting works.

◇ Challenge

Historic drain networks were undocumented and the trust needed to know where water would go before breaching bunds.

◇ Approach

Low-sun LiDAR sorties for clean ground returns through rush and raupō, hydro-conditioned DTM with flow paths and ponding extents modelled at four outlet scenarios; multispectral capture for a vegetation health baseline.

◇ Outcome

Re-wetting staged around two drains the model showed would back-flood a neighbour. Baseline NDVI layer now used for annual recovery monitoring.
