Montane lakes (lagoons) of the New England Tablelands Bioregion

The vegetation of montane lagoons of the New England Tablelands Bioregion, New South Wales is examined using flexible UPGMA analysis of frequency scores on all vascular plant taxa, charophytes and one liverworts. Seven communities are described- 1. 'Hydrocotyle tripartita' - 'Isotoma fluviatilis' - 'Ranunculus inundatus' - 'Lilaeopsis polyantha' herbfield; 2. 'Eleocharis sphacelata' - 'Potamogeton tricarinatus' sedgeland; 3. 'Eleocharis sphacelata' - 'Ultricularia australis' - 'Isolepis fluitans', herbfield; 4. 'Ultricularia australis' - 'Nitella sonderi' herbfield; 5. 'Eleocharis shacelata' - Ultricularia australis' - 'Ricciocarpus natans' sedgeland; 6. 'Carex gaudichaudiana' - 'Holcus lanatus' - 'Stellaria augustfolia' sedgeland; 7. 'Cyperus sphaeroides' - 'Eleocharis gracilis' - 'Schoenus apogon' - 'Carex gaudichaudiana' sedgeland. 58 lagoons were located and identified, only 28% of which are considered to be intact and in good condition. Two threatened species ('Aldovandra vesiculosa' and 'Arthaxon hispidus') and three RoTAP-listed taxa were encountered during the survey.
