Ephemeral wetlands in Aotearoa | New Zealand kettle holes: geographic range, botanical biodiversity values and underlying land tenures
Ephemeral wetlands are naturally uncommon ecosystems that have become threatened in Aotearoa | New Zealand and include many glacially derived kettle holes (kettles) of the South Island. These kettles can be easily overlooked as wetlands, particularly when in a dry phase, thereby increasing their vulnerability.
