Random sampling means the selection of a subset of data points from a larger population such that each data point is chosen randomly and s each individual has the same probability of being chosen at each stage of the sampling process. This is an unbiased surveying technique. Sequestration determination means the Carbon Credits (Carbon Farming Fire and Emissions Avoidance) Methodology Determination 2018. Sequestration Savanna

Erythrophleum, Terminalia, Xanthostemon) May contain Melaleuca. spp. shrub layer may/may not be present; may include woody heath taxa Rocky shallow soils derived typically from sandstone (quartzite); also lateritic hills and plateau lWMi Woodland with mixed tussock / hummock grasses Canopy Trees Majority of trees >10 m 10-30 % Dominated by native perennial and annual tussock grasses; may be associated with hummock (Triodia) grasses. May include limited areas of open forest with tussock/mixed grass Various Eucalyptus (for example, E. tetrodonta) and Corymbia spp, often with other taxa (for example, Erythrophleum, Terminalia, Callitris) May contain Melaleuca. spp. shrub layer may/may not be present. Various situations including undulating to hilly land types on imperfectly to drained soils

Majority deep drained soils to those with impeded drainage, typically on flat to undulating land types with fertile substrates lOWM Open woodland with mixed grasses Canopy Trees Majority of trees <10 m <10 % Dominated by hummock (Triodia) grasses, or codominant with tussock grasses Various Eucalyptus and Corymbia, including C. dichromophloia, E. leucophloia, E. brevifolia, E. pruinosa, E. tectifica layer may/may not be present. Where present, may include woody heath taxa Shallow substrates on undulating stony rises and rocky hills
lSHH Shrubland with hummock grasses Shrubs Majority of shrubs <5 m <30 % Hummock (Triodia) grasses, and/or other perennial members of the Restionaceae (Lepyrodia, Dapsilanthus) sedges (Schoenus sparteus) or graminoids (for example, Lomandra, Xanthorrhoea) Sparse trees. May include areas of low open Melaleuca hummock grassland Conspicuous (heath) layer, commonly Acacia species and various other taxa (for example, Calytrix, Grevillea, Hibbertia, Hibiscus, Jacksonia, Tephrosia, Veritcordia ) Sand plains often over laterite, or rocky, shallow substrates derived from sandstone
