Description

Grey box-grey gum wetforest is a tall to very tall open forest, dominated by eucalypts andsometimes hoop pine (Araucariacunninghamii), with an understorey of dry vine forest or grassy forestspecies. The canopy is characterised by Eucalyptusmoluccana (grey box) and/or one or both of E. propinqua (small-fruited grey gum) and E. punctata5 (grey gum). In addition,it often includes E. siderophloia (greyironbark) and/or Araucaria cunninghamii (hooppine). The mid stratum is variable, however often includes trees and shrubssuch as Psydrax odorata (shiny-leavedcanthium), Denhamia bilocularis (orangebark) and Cupaniopsis parvifolia (small-leavedtuckeroo), the shrubs Psychotriadaphnoides (smooth psychotria) and Alyxiaruscifolia (chain-fruit). Vines include Celastrussubspicatus (large-leaved staff vine),Solori involuta (native derris) and Macluracochinchinensis (Cock-spur). Graminoids include Gahnia aspera (Sword Sedge),Cyperus gracilis (slender flat-sedge) Ottochloagracillima (pademelon grass) and Oplismenusspp. (basket grasses). In more open grassy areas, species may includejuveniles of Eucalyptus spp.(eucalypts), Acacia spp. (wattles), Allocasuarina torulosa (forest she-oak), Dodonaea viscosa (sticky hop-bush), Leucopogon ericoides (heath-leavedbeard-heath), Leucopogon juniperinus (pricklybeard-heath), Imperata cylindrica (bladygrass), Aristida gracilipes (three-awnspear-grass), Poa labillardierei (tussock), Cymbopogon refractus (barbed-wiregrass) and Glycine clandestine (twining glycine).


Distribution

This community is limited to the New South Wales north coastand south eastern Queensland IBRA Bioregions from near Coffs Harbour in NSW to the southernareas of south- east Queensland. It occurs mainly in the Richmond and ClarenceRiver Catchments NSW (DEC 2008) with some occurrences in other catchments.


Habitat and ecology

  • typically occurs on escarpment slopes and foothills, on inland hills and ranges at altitudes between 100m and 600m above sea level (ASL) and mostly with an annual rainfall between 1000mm to 1260mm.
  • occurs on fertile, well drained soils which are derived mostly from fine-grained sedimentary rocks, sometimes with local volcanic influence, or less commonly on soils derived from other geologies such as fine grained sedimentary or volcanic rocks.
  • does not occur on broader alluvial landforms such as floodplains, alluvial flats, older floodplain terraces and periodically flooded depressions.
