Abstract: | In comparison to the northern hemisphere, Sphagnum peatlands are an unusual andinfrequent component of the Australasianlandscape. Most peatlands in Australasiaare primarily composed of eitherRestionaceous or Cyperaceous peats. Sphagnum peatlands in Australia and PapuaNew Guinea/Irian Jaya (now West Papua) arelargely located in montane and alpineenvironments, but also occur down to sealevel in New Zealand and as moss patches onsome subantarctic islands. Fire is a majordeterminant of the characteristics ofpeatlands in Australasia. Peatlandmanagement in Australasia is hindered bythe need for increased understanding ofpeatland processes to enable a sustainablebalance of conservation of a small resourcewith localised utilisation. Themanagement focus in Australasia has largelybeen on ensuring ecologically sustainable Sphagnum moss harvesting, withlimited peat mining. We have found thatgeneral recovery of Sphagnum after moss harvesting canbe enhanced by harvesting larger peatlands,and by leaving one-third of the acrotelm toregenerate. The largest upland peat swampin mainland Australia, Wingecarribee Swamp,suffered a major collapse in 1998 followingpeat mining. Environmental and managementconsequences of this collapse have majorramifications for rehabilitation options. Sphagnum peatlands in Australasia arelikely to be adversely affected bydrainage, burning, grazing, trampling,global warming and peat mining. |
