Site Description

The Dargo High Plains flux station was located in high elevation (1650m), sub-alpine grassland in North-East Victoria (GPS coordinates: -37.1334, 147.171),

The site was in a naturally occurring open grass/herb-field classified as sod tussock grassland. The dominant species comprised of various Poa spp. Surrounding the open grasslands were ridge top distributions of Eucalyptus pauciflora spp. niphophila/Eucalyptus pauciflora spp. pauciflora. The high country is characterised by elevated plateaus with steep montane country.

Various eucalypts formed a replacement series with decreasing elevation. This site was seasonally grazed and also hosted long-term research plots established by the Bushfire CRC to robustly examine effects of fire and grazing in the sub-alpine.

The instrument tripod was 3m tall with a supplemental 4m guyed mast for radiation sensors. Fluxes of carbon dioxide, water vapour and heat were quantified with open-path eddy covariance instrumentation.

Ancillary measurements included temperature, air humidity, wind speed and direction, precipitation, incoming and outgoing shortwave radiation, incoming and outgoing long wave radiation, incoming total and diffuse PAR and reflected PAR.

Soil water content and temperature were measured at six soil depths. Surface soil heat fluxes were also measured.
