Description
The Buloke Woodlands of the Riverina and Murray-Darling Depression Bioregions occur substantially within the two named bioregions, which are described in the report edited by Thackway and Cresswell (1995). The woodlands are distributed widely across the bioregions, occurring in tracts or as patches within open forests or woodlands dominated by other species. A feature common to many areas where the woodlands occur is the presence of clayey and/or alkaline sub-soils. In many of the South Australian areas, massive calcrete underlies the sub-soil at depths of less than one metre.
The nominated woodland's component communities are generally characterised as woodland or open woodland with a well developed ground stratum that is usually grassy, but also includes many subshrubs and herbs; some component communities have understoreys that are predominantly shrubby or herbaceous. Most component communities lack a well-developed tall shrub layer. Buloke is common to all component communities, but slender cypress-pine and grey box may be structurally dominant in some. The composition of the ground stratum varies considerably among component communities. Native grasses often include wallaby grasses, Danthonia spp., and spear grasses, Stipa spp. Exotic grasses, which are frequently abundant, include Wimmera rye grass, Lolium ridigum, and several bromes, Bromus spp. Native subshrubs and herbs may include nodding saltbush, Einadia nutans, variable groundsel, Senecio pinnatifolius, variable sida, Sida corrugata, New Holland daisies, Vittadinia spp., grassy bindweed, Convolvulus remotus, and wingless bluebush, Maireana enchylaenioides. Exotic herbs may include clovers, Trifolium spp., sand catchfly, Sinene apetala, skeleton weed, Chondrilla juncea, and common pepper-cress, Lepidium africanum. The community is an important source of food for the endangered South-eastern Red-tailed Black-Cockatoo.
The woodlands have been extensively cleared in the past, and the remnants that survive face ongoing major threats from incremental clearance, grazing by rabbits and stock, invasion by exotic plants, weedicide application and fertiliser drift. The community is poorly represented in conservation reserves throughout its range. In order to meet the definition of the TEC sites must satisfy condition criteria stipulated in the Listing Advice and/or Conservation Advice. Typically condition is assessed by reference to patch size and vegetation structure thresholds or species composition metrics.
