Description

This community, commonly referred to as Tablelands Snow Gum Grassy Woodland, occurs as an open-forest, woodland or open woodland. This community may also occur as a secondary grassland where the trees have been removed, but the groundlayer remains. The the main tree species are Eucalyptus pauciflora (Snow Gum), E. rubida (Candlebark), E. stellulata (Back Sallee) and E. viminalis (Ribbon Gum), either alone or in various combinations. Other eucalypt species may occur. A shrub layer may be present and sub-shrubs are common. The most common shrubs include Melicytus sp. 'Snowfileds' (Gruggly-bush) and Melichrus urceolatus (Urn Heath). The ground layer is grassy, with the most common species including Themeda australis (Kangaroo Grass), Poa spp. (snow-grasses), Austrostipa spp. (spear-grasses) and Rytidosperma spp. (wallaby-grasses). Sites in high condition have a range of forb (wildlfower) species, including Leptorhynchos squamatus (Scaly-buttons), Chrysocephalum apiculatum (Common Everlastings) and Asperula conferta (Native Woodlruff). Many threatened flora and fauna species have been recorded in this community. The community commonly occurs on valley floors, margins of frost hollows and on footslopes and undulating hills. It occurs between approximately 600 and 1400 m in altitude on a variety of substrates, including basalt, sediments, granite, colluvium and alluvium.

Distribution

Tablelands Snow Gum Grassy Woodland occurs in the South Eastern Highlands Bioregion; part of this region is the 'Southern Tablelands' and the northern section of the bioregion is the 'Central Tablelands. There are outlying occurrences of this community in the Sydney Basin, South East Corner and NSW South Western Slopes Bioregions, where suitable habitat exists.

Habitat and ecology

  • Characterised by the presence or prior occurrence of Snow Gum, Candlebark, Ribbon Gum and/or Black Sallee trees.
  • The trees may occur as pure stands, mixtures of the four species or in mixtures with other trees, including wattles.
  • Commonly co-occurring eucalypts include Apple Box (Eucalyptus bridgesiana), Swamp Gum (E. ovata), Black Gum (E. aggregata), Mountain Gum (E. dalrympleana), Broad-leaved Peppermint (E. dives) and Narrow-leaved Peppermint (E. radiata) and commonly occurring tree-layer or mid-layer wattles include Blackwood (Acacia melanoxylon) and Silver Wattle (A. dealbata).
  • The understorey in intact sites is characterised by native grasses and a high diversity of herbs; the most commonly encountered include Kangaroo Grass (Themeda australis), Common Snow-grass (Poa sieberiana), River Tussock (Poa labillardierei), Short Snow-grass (Poa meionectes), various wallaby-grasses (Rytidosperma spp.), various spear-grasses (Austrostipa spp.), Common Everlasting (Chrysocephalum apiculatum), Scaly-buttons (Leptorhynchos squamatus), Common Woodruff (Asperula conferta), Wattle Mat-rush (Lomandra filiformis), St John's Wort (Hypericum gramineum), Stinking Pennywort (Hydrocotyle laxiflora) and Slender Tick-trefoil (Desmodium varians ).
  • Shrubs are generally sparse or absent, though they may be locally common. Sub-shrubs (woody species <0.5 m tall) may be common. The most common shrubs and sub-shrubs include Gruggly-bush (Melicytus sp. 'Snowfields'), Urn Heath (Meichrus urceolatus), Sweet Bursaria (Bursaria spinosa) and Mountain Mirbelia (Mirbelia oxylobioides ).
  • Remnants may occur on the lower, more fertile parts of the landscape where resources such as water and nutrients are abundant; sites on midslope situations where resources are scarcer are more common.
  • Sites with particular characteristics, including varying age classes in the trees, patches of regrowth, old trees with hollows and fallen timber on the ground are very important as wildlife habitat; sites with a full range of such attributes are rare.
  • Sites in the lowest parts of the landscape often support large trees which have leafy crowns and reliable nectar flows - sites important for insectivorous and nectar feeding birds; such trees also ahve the largest hollows.
  • Sites that retain only a grassy groundlayer and with few or no trees remaining are important for rehabilitation, and to rebuild connections between sites of better quality.
  • Remnants support many species of threatened fauna and flora.
  • Retention of remnants is important as they contribute to productive farming systems (stock shelter, seed sources, sustainable grazing and water-table and salinity control).
  • The fauna of remnants (insectivorous birds, bats, etc) can contribute to insect control on grazing properties.
  • Some of the component species (e.g. wattles, native legumes) fix nitrogen that is made available to other species in the community, while fallen timber and leaves recycle their nutrients.
  • Disturbed remnants are considered to form part of the community, including where the vegetation would respond to assisted natural regeneration.
