Raised mires occur on an emerging marine terrace of Holocene age at Handspike Point, Macquarie Island, and slope seawards. Ponions of these mires are characterised by numerous, anastomosing to parallel, low peat ridges, separated by waterlogged troughs. The resulting patterns arc accentuated by the distinctive rosette plant Pleurophyllurn hookeri, which grows only on the ridges. Sampling suggests that ridge and trough patterns persist to at least l.)m depth. Pleurophy/lum colonisation appears to be a function of the difference in trough: ridge peat bulk density. As chis density ratio approaches 0.8, waterlogging decreases and Pleurophyllurn vigour is enhanced.
Patterns are oriented at various angles to the present surface slopes, bur roughly parallel to the plateau margin and normal to the regional slope of the marine terrace. The divergence between pattern and local contour orientation results from non-uniform accretion. Patterns at angles to the contours appear to provide benefits which include enhanced water-level stability.
The Handspike mires exhibit many characteristics of patterned and non-pancrned peatlands ubiquitous throughout the Northern Hemisphere, with particular similarities to eccentric domed mires of the Baltic region. Vertical accretion is estimated to average 1mm yr-1; lateral accretion appears to be in equilibrium with the emerging marine terrace.

The Royal Society of Tasmania acknowledges, with deep respect, the traditional owners of this land, and the ongoing custodianship of the Aboriginal people of Tasmania. The Society pays respect to Elders past, present and emerging. We acknowledge that Tasmanian Aboriginal Peoples have survived severe and unjust impacts resulting from invasion and dispossession of their Country. As an institution dedicated to the advancement of knowledge, the Royal Society of Tasmania recognises Aboriginal cultural knowledge and practices and seeks to respect and honour these traditions and the deep understanding they represent.
On 15 February 2021, the Royal Society of Tasmania offered a formal Apology to the Tasmanian Aboriginal people.
