Land Resources of Auvergne Station A supplement to the Land Resources of the Victoria River District 45 Bauhinia cunninghamii low open woodland with Chrysopogon fallax tussock grassland understorey. Land units: 7l2A, 8l6V Stratum Growth form Cover (cover range) % Av Height (height range) m Upper Tree 13 (2-45) 6.2 (4.5-9.5) Mid Shrub 5 (0-20) 1.8 Ground Tussock Grass 64 (25-90) 0.35 (0.2-0.6) Bauhinia cunninghamii is dominant of the upper stratum, often with the occasional Terminalia volucris and/or Excoecaria parvifolia. The structural formation of the upper stratum is generally low open woodland although low woodland also occurs. The mid stratum is absent or sparse and may include overstorey species and/or Atalaya hemiglauca, A. salicifolia, Acacia lamprocarpa and occasionally Hakea arborescens. The ground stratum is predominantly a Chrysopogon fallax/Brachyachne convergens grassland although various other grasses and herbs occur. The grasses include, amongst others, Aristida latifolia, Astrebla spp., Sehima nervosum and Panicum decompositum and the herbs Polymeria ambigua, Euphorbia maconochie and Crinum spp. The sedge Cyperus bifax is also present on occasion. Tussock grassland communities Chrysopogon fallax/Brachyachne convergens/Iseilema tussock grassland. Land unit: 7lA Stratum Growth form Cover (cover range) % Av Height (height range) m Ground Tussock Grass 71 (40-98) 0.4 (0.25-0.8) Chrysopogon fallax, Iseilema vaginiflorum and I. fragile are locally dominant, co-dominant or form monospecific stands. Other common, though less abundant species include the grasses Aristida latifolia and Panicum decompositum, the herb Polymeria ambigua, the vine Cucumis melo and the shrub Sesbania simpliciuscula. This is a fairly common community, occurring in 25% of all sites assessed. It can occur as a pure grassland or in association with overstorey species which range structurally from sparse low open woodlands to woodlands and include the species Eucalyptus microtheca, Excoecaria parvifolia, Bauhinia cunninghamii and various other eucalyptus species.
