Glossary for the current state story

Seven Day Mean Annual Low Flow (MALF(7d): Seven Day Mean Annual Low Flow (MALF(7d)) is determined by adding the lowest seven day low flow for every year of record and dividing by the number of years of record. (In any year the seven-day low flow is the lowest average flow sustained over seven consecutive days)

Silent files: Silent files are areas identified by Papatipu Rūnanga as requiring special protection due to the presence of significant wāhi tapu (sacred places) or wāhi taonga (treasured possessions) in the area. Where activities occur in silent file areas, consultation with Papatipu Rūnanga is particularly important in order to identify effects of the activity and avoid, remedy or mitigate those effects. Absence of a silent file area on GIS does not mean there are no wāhi tapu or wāhi taonga sites in the area. Rather, presence of a silent file indicates the presence of a significant wāhi tapu or wāhi taonga site.

Stormwater: Is the runoff of water that is unabsorbed due to impermeable surfaces (such as roading), which then flows into gutters or directly into waterways

Stygofauna: Any organism that lives in groundwater systems such as caves or alluvial aquifers

Supporting services: The underlying natural functions that species within ecosystems undertake to maintain and regulate the wider environment that they are a part of
