Naree and Yantabulla stations (31,990 ha) are found 60 km south-east of Hungerford and 112 km north-west of Bourke, New South Wales (lat. 29° 55'S; long. 150°37'N). The properties occur on the Cuttaburra Creek within the Mulga Lands Bioregion. We describe the vegetation assemblages found on these properties within three hierarchical levels (Group, Alliance & Association). Vegetation levels are defined based on flexible UPGMA analysis of coverabundance scores of all vascular plant taxa. These vegetation units are mapped based on extensive ground truthing, SPOT5 imagery interpretation and substrate. Three ‘Group’ level vegetation types are described: Mulga Complex, Shrublands Complex and Floodplain Wetlands Complex. Within these Groups nine ‘Alliances’ are described: Rat’s tail Couch – Lovegrass Grasslands, Canegrass Grasslands, Lignum – Glinus Shrublands, Coolibah – Black Box Woodlands, Turpentine – Button Grass – Windmill Grass Shrublands, Turpentine – Hop Bush – Kerosene Grass shrublands and Mulga Shrublands. Sixteen ‘Associations’ are described 1) Mulga – Poplar Box Shrubland, 2) Mulga – Poplar Box – Bastard Mulga Shrubland, 3) Turpentine – Hop Bush – Senna Shrubland, 4) Turpentine – Elegant Wattle – Boobialla Shrubland, 5) Turpentine – Hop Bush – Daisy Bush Shrubland, 5) Belah – Rosewood – Turpentine Bush Shrubland, 6) Belah – Rosewood – Turpentine Bush Shrubland, 7) Ironwood – Leopardwood – Supplejack Shrubland, 8) Yapunyah – Black Box – River Cooba Woodland, 9) Coolibah – River Cooba – Yapunyah Woodland, 10) Rat’s tail Couch – Lovegrass – Fairy Grass Grassland and Herbfield, 11) Rat’s tail Couch – Lovegrass – Purslane Grassland and Herbfield, 12) Darling Pratia – Rat’s tail Couch – Spike Rush Herbfield, 13) Canegrass Grassland, 14) Glinus – Groundsel – Lignum Herbfield, 15) Poplar Box – Mulga – Coolibah Woodland and 16) Black Box Woodland. In total 355 vascular plant taxa were found of which 6% were considered exotic in origin. A population of Dentella minutissima; a species listed as threatened (endangered) under the New South Wales Threatened Species Conservation Act 1995 was found. A summary of select structural and habitat attributes within Alliances is also presented.
Vegetation of montane bogs in east-flowing catchments of northern New England, New South Wales
(2007)
The floristics of the montane bogs in east-flowing catchments of northern New England, north-eastern New South Wales (lat 28° 47’–31° 25’ S; long 151° 50’–152° 30’ E), are described from 62 full floristic survey sites (20 x 20 m in area). Eight vegetation communities are based on flexible UPGMA analysis of cover-abundance scores of vascular plant taxa. Shrub species make up 26% of the flora and herb species 69%, with the remaining taxa trees, climbers or vines. Shrub species were of little diagnostic value, as a few common dominants were shared across most communities. The herbaceous layer was found to be of better circumscriptive value. Communities described (based on dominant herbaceous species) are: (1) Themeda australis – Gonocarpus micranthus, (2) Baumea articulata – Baloskion stenocoleum, (3) Lepidosperma limicola – Baloskion stenocoleum, (4) Baloskion fimbriatum – Lomandra longifolia, (5) Lepyrodia scariosa – Blandfordia grandiflora, (6) Lepidosperma gunnii – Lepidosperma scariosa, (7) Baloskion stenocoleum – Empodisma minus, (8) Lepidosperma limicola – Xyris operculata. The mean annual moisture index was found to account for 26% of the variation in species density. These montane bog systems are some of the richest in Australia, with a high number of rare and restricted taxa. They are vulnerable to both present landuse practices and future changes in climate, are restricted in area, and need further conservation efforts to ensure their long-term survival.
Vegetation of Little Bora Nature Conservation Trust Agreement, North Western Slopes, New South Wales
(2014)
The vegetation of the Little Bora Nature Conservation Trust Agreement property (560 ha in area), 8 km south east of Bingara (lat 29° 55’S long 150° 37’) in the Gwydir Shire and within the Nandewar Bioregion is described. Eight vegetation communities are defined based on flexible UPGMA analysis of cover-abundance scores of all vascular plant taxa. These communities are mapped based on ground truthing, ADS40 imagery interpretation, topography and substrate. Communities described are: 1) Melaleuca bracteata – Eucalyptus melanophloia – Eucalyptus camaldulensis Woodland, 2) Callitris glaucophylla – Eucalyptus melanophloia – Eucalyptus albens Woodland, 3) Callitris glaucophylla – Eucalyptus melanophloia – Brachychiton populneus Woodland, 4) Eucalyptus albens Woodland, 5) Eucalyptus caleyi – Eucalyptus albens – Callitris glaucophylla Woodland, 6) Callitris glaucophylla – Eucalyptus melanophloia – Eucalyptus albens Woodland, 7) Austrostipa verticillata – Austrostipa scabra Derived Grassland, 8) Eucalyptus melliodora – Eucalyptus dealbata Woodland. A total of 232 vascular plant taxa were found of which 14% were considered exotic in origin. 66 ha of listed threatened communities were mapped along with populations of a currently listed Extinct plant (TSC Act) Dodonaea stenophylla.
The vegetation of Ironbark Nature Reserve (1603 ha) and Bornhardtia Voluntary Conservation Agreement (704 ha), 75 km north west of Armidale, 30 km north east of Barraba (30°19’S, 150°53’E) in the Barraba Shire, in the Northern Tablelands Bioregion NSW, is described. Eleven communities are defined based on flexible UPGMA analysis of coverabundance scores of all vascular plant taxa. These communities are mapped based on ground truthing, air photo interpretation and substrate. All communities are simple in structure being primarily of woodlands or shrublands.
Communities described are: (1) Eucalyptus macrorhyncha (Red Stringybark) – Eucalyptus blakelyi (Red Gum) Woodlands, (2) Eucalyptus caleyi (Caley’s Ironbark) – Eucalyptus andrewsii (Western New England Blackbutt) Woodlands, (3) Eucalyptus prava (Orange Gum) – Eucalyptus andrewsii (Western New England Blackbutt) Woodlands, (4) Eucalyptus dealbata (Tumbledown Gum) – Eucalyptus caleyi (Caley’s Ironbark) Woodlands, (5) Eucalyptus prava (Orange Gum) – Eucalyptus blakelyi (Red Gum) Woodlands, (6) Eucalyptus quinniorum (Quinn’s Gum) – Eucalyptus prava (Orange Gum) Forests, (7) Angophora floribunda (Rough-barked Apple) – Eucalyptus blakelyi (Red Gum) Woodlands, (8) Casuarina cunninghamiana (River Oak) – Eucalyptus blakelyi (Red Gum) – Angophora floribunda (Apple) Forests, (9) Calytrix tetragona (Fringe Myrtle) – Ozothamnus obcordatus (Daisy Bush) Open Shrublands, (10) Homoranthus bornhardtiensis Open Shrublands and (11) Leptospermum polygalifolium (Tea-tree) Wetland.
All communities described here are inadequately represented in the conservation network with one (White-Box – Yellow-Box – Blakely's Red Gum Woodland) listed as endangered on the NSW TSC Act. Both conservation areas and neighbouring parcels of land contain extensive areas of little disturbed high quality "old growth". 38 species are of conservation significance of which one is listed as Vulnerable and one Endangered on the NSW TSC Act. The broader remnant is under increasing pressure for clearing for grazing production and the combined area of both reserves is considered to be inadequate to protect the significant features of the local region.
The vegetation of Imbota Nature Reserve (30° 35’S, 151° 45’E) (218 ha in area), 10 km south-east of Armidale, and Yina Nature Reserve (30° 29’S, 151° 45’E), (101 ha in area), 10 km east of Armidale, on the Northern Tablelands, NSW, is described. Based on classification analyses, air photo interpretation and ground-truthing, seven vegetation communities are described and mapped : 1. Eucalyptus caliginosa (Broad-leaved Stringybark) Grassy Forest and Woodland on deep soils at Imbota; 2. Eucalyptus viminalis (Manna Gum) Grassy Forest and Woodland, Community; 3. Eucalyptus caliginosa (Broad-leaved Stringybark) Grassy Forest and Woodland on shallow soils at Imbota; 4. Eucalyptus caliginosa (Broad-leaved Stringybark) Grassy Forest and Woodland at Yina; 5. Eucalyptus blakelyi (Blakely’s Red Gum) – Eucalyptus melliodora (Yellow Box) Woodland; 6. Eucalyptus viminalis (Manna Gum) – Eucalyptus nova-anglica (New England Peppermint) Grassy Forest and Woodland and 7. Riparian Herbfields 252 vascular plant taxa (from 59 families) were recorded from the two reserves, 179 species in Imbota NR, the larger reserve and 209 in Yina NR. The lower species richness at Imbota is likely to have resulted human disturbance rather than from overall habitat heterogeneity.

A floristic survey of 40 x 0.1 ha plots within the Demon Nature Reserve, 30 km east-south-east (lat. 29°05'S, long 152°15'E) of Tenterfield, was conducted in March, 1997. The Reserve (887 hectares in area) is on a western facing escarpment ranging from 500–1000 m above sea level. The survey data were analysed and seven vegetation communities defined. This paper describes the seven communities and discusses their significance and distribution within the reserve. A vegetation map and plant species list are provided.
The vegetation of Mount Canobolas State Recreation Area (1673 ha), 14 km southwest of Orange (33°21’S, 154°59’E) in the Shire of Cabonne on the Central Tablelands of New South Wales is described. A floristic survey of 50x0.04 ha plots was conducted in November 1999. Seven communities are defined based on flexible UPGMA analysis of abundance scores of vascular plant taxa. Mapping of these communities is based on ground truthing, air photo interpretation and substrate. A total of 309 taxa was recorded including two species listed under the NSW Threatened Species Conservation Act 1995: Eucalyptus canobolensis and Eucalyptus saxicola. Additionally the reserve contains the Mount Canobolas Xanthoparmelia lichen community recently listed on the NSW Threatened Species Conservation Act 1995. This paper describes the seven communities and discusses their significance and distribution within the Recreation Area. A vegetation map and species list are provided.
