Value

Description

A1

Habitat for nationally or internationally rare or threatened species or communities. Habitat for threatened Banded Dotterel (Charadrius bicinctus bicinctus) and Black-fronted Tern (Sterna albostriata). 1
Presence of Deschampsia cespitosa (At Risk – Declining). 102

A5

Scarce in Otago in terms of its ecological or physical character. Likely to meet criterion A5 as it is located in Dart Ecological District and partly in the Richardson Ecological District where lakes and ponds and herbaceous freshwater vegetation comprise less than 2% and c. 10.4% of land cover respectively. 102

A6

Highly valued by Kai Tahu for cultural and spiritual beliefs, values and uses, including mahika kai and waahi taoka. 1

A7

High diversity of indigenous wetland flora and fauna. High diversity of fauna. The wetland complex that comprises Diamond Lake Wetland and the nearby Lake Reid Wetland provide nesting and feeding habitat for Paradise Shelduck (Tadorna variegata), Black Swan (Cygnus atratus), Pied Stilt (Himantopus himantopus), Southern Black-backed Gull (Larus dominicanus), South Island Pied Oystercatcher (Haematopus ostralegus finschi) and Shags (Phalacrocoracidae). 1

A9

Significant hydrological function, including maintaining water quality, or low flows, or reducing flood flows. Likely to meet Criterion A9, as the wetland filters water entering Lake Reid and are part of the larger Lake Reid-Diamond Lake wetland complex. 102

  • Wetland habitats in the north-eastern part of the wetland are dominated by rautahi and other Carex spp. but also Yorkshire fog and sweet vernal, with scattered Juncus effusus and Luzula multiflora. 102

  • There are a few areas where Sphagnum moss, Gonocarpus micranthus, Celmisia gracilenta, and patchy Oreobolus pectinatus are present, possibly outside the boundary of the mapped site. 102

  • The southernmost part of the wetland is more modified and contains scattered Juncus effuses over sweet vernal and Yorkshire fog, with sharp spike-sedge (Eleocharis acuta), Juncus articulatus, moss, and Gonocarpus micranthus. 102
