Common name: Turpentine scrub – Gaultheria montane shrubland
Code: A: S5
Where does it occur?
This shrubland occurs on the S.I. east of the Main Divide at altitudes ranging from 730 to 1360 m and is generally less than 2 m in height.
Description
This alliance is dominated by Dracophyllum uniflorum in the canopy over the smaller shrubs Gaultheria crassa and G. depressa, the grasses Poa colensoi and Festuca novae-zelandiae and the herb Wahlenbergia albomarginata. The shrub Ozothamnus leptophyllus and the tall tussocks Chionochloa rigida and C. flavescens may be present. Strong indicator species include Dracophyllum uniflorum, Gaultheria crassa, and Celmisia spectabilis. Species richness is moderate, with on average 37 species per plot. Exotic species richness is also moderate, with on average 5 exotics species (13% of the total richness) on each plot.
Indicator species
Co-occurrence of Dracophyllum uniflorum and either Festuca novae-zelandiae or Celmisia spectabilis.
