Estimated percentage landcover for vegetation class

Structure

Dense sedgleland with scattered emergent sclerophyllous shrubs

Trees

Typically none, but may have scattered individuals of Eucalyptus stellulata, E. aquatica, E. parvifolia, E. latiuscula or E. dalrympleana

Shrubs and vines

Hakea microcarpa, Baeckea utilis, B. gunniana, B. linifolia, Epacris breviflora, E. paludosa, Leptospermum myrtifolium, Grevillea acanthifolia, Epacris microphylla var. rhomboidea, E. paludosa, E. breviflora, Leptospermum myrtifolium, L. grandifolium, L. obovatum, L. gregarium, Callistemon pityoides, Boronia deanei, with Leptospermum gregarium and Baeckea omissa on New England tableland

Forbs, graminoids and pteridophytes

Baloskion australe, B. stenocoleum (on New England), Empodisma minus, Lepyrodia anarthria, Schoenus apogon, Gonocarpus micranthus ssp. micranthus, Stylidium graminifolium, Asperula gunnii, Carex appressa, C. gaudichaudiana, Hydrocotyle pedunculata, H. tripartita, Hypericum japonicum, Poa sieberiana var. sieberiana, P. labillardieri var. labillardieri, Euchiton gymnocephalus, Austrofestuca hookeriana, Epilobium billardierianum ssp. hydrophilum, E. gunnianum, Juncus falcatus, Oreomyrrhis ciliata, Ranunculus pimpinellifolius, Pratia surrepens, Mitrasacme serpyllifolia, Geranium neglectum, with Gymnoschoenus sphaerocephalus, Gleichenia dicarpa and Stylidium graminifolium at less fertile sites. Sphagnum cristatum abundant at some sites.

Habitat

Poorly drained headwater valleys with moderately fertile loamy peats and humic clay loams on the eastern edge of the tableland

Distribution

Scattered along eastern edge of the tablelands south from New England, Werrikimbee, upper Blue Mountains, Penrose-Robertson and Monaro region extending to the Gippsland highlands. Mapped occurrences on the far north coast are modelling artefacts in NPWS (1999).

Notes

Widespread but locally restricted group of assemblages whose composition varies markedly with latitude and soil chemistry. Nutrient-poor bogs on sandstone and some granitoid substrates are dominated by shrubs, while those with more fertile soils are dominated by sedges. Peat deposits contain local palynological histories. A substantial proportion of bogs are degraded by grazing, pasture improvement within catchments and peat mining.
