Coastal / Marine Biodiversity

Tasman District has significant coastal ecological resources including:

  • eight sites of international significance for shorebirds (Farewell Spit is also a RAMSAR site),
  • the second and third largest estuaries in the South Island (Waimea and Wanganui Inlets respectively),
  • large areas of natural dunelands (Farewell Spit),
  • large areas of seagrass communities (particularly around Wanganui Inlet and Puponga-Pakawau),
  • salt turf communities of the West Coast part of the region,
  • Tonga Island Marine Reserve and
  • large areas of natural terrestrial coastal margins (around Abel Tasman and West Coast).

Most of Council’s biodiversity monitoring in the coastal environment involves broad-scale mapping of habitats in estuaries and 200m coastal terrestrial margin as well as fine-scale assessments of muddy environments in estuaries. More recently Council has partnered with Birds NZ to produce reports about shorebird communities of Tasman’s coast.
