“…There mire-like vegetation lacking cushions, such as Carex-Gentianella mire (H) occurs. Cushions are well known from blanket mires in the subalpine zone of the South Island, New Zealand (Burrows 1969;Burrows & Dobson 1972;Johnson et al 1977;Lough et al 1987;Mark & Wilson 2005), and they are also important in domed mires (McQueen & Wilson 2000). Gaimardia setacea (Centrolepidaceae), Oreobolus pectinatus (Cyperaceae), and Donatia novae-zelandiae (Donatiaceae) are the most common cushions in the Lammerlaw mires, tending to occur in the better-drained communities at the margins or base of the mires (J, Celmisia-Gentianella-Sphagnum mire base; N, Donatia herbfield; R, Oreobolus cushion mire; S, Gaimardia mire).…”

“…In New Zealand this species is widespread in such environments (Burrows 1969;Dobson 1977;Mark et al 1995), and is indicative of oligotrophic conditions, as Dickinson et al (2002) recorded for Roaring Lion mire, which nutrient analysis indicated was minerotrophic to marginally ombrotrophic. In shallow depressions, Sphagnum falcatulum occurs (Vegetation type V), a species which is normally confined to hollows and shallow pools (Burrows 1969;Dobson 1979), or domed mires (McQueen & Wilson 2000), indicating tolerance of extremely low nutrient levels. Mark et al (1995) found Isolepis aucklandica also typical of pools on the Garvie Mountain aapa mires, though it is unimportant in pools here, instead being more common on pool margins and other drier sites (Vegetation types E, G, Q, R, T).…”

“…New Zealand domed bogs occur in both North and South Islands near sea level in high rainfall areas (Mark et al 1979;Agnew et al 1993;McQueen & Wilson 2000;Clarkson et al 2000), and on nearby Chatham Island (Clarkson et al 2004). Eccentric mires are limited to rainy Fiordland, as only Dome and Kepler mires (Burrows & Dobson 1972;Gregorie 1983) appear to qualify.…”

Vegetation patterns of subalpine gullyhead mires were investigated in the flat-topped Lammerlaw and Lammermoor Ranges, South Island, New Zealand. Two intensively studied mires each consist of a series of peaty terraces and scarps. Terraces may contain pools, elongated downslope in the narrow, lower altitude mire, but across slope in the broader, upper mire. A crest occurs on some terrace lips, and marginal "spillways" (channel-like zones) occur down some scarps. Some mires have drained by subsurface pipes.Vegetation analysis distinguished between grassland or herbfield on gully sides, vegetation of mire margins, showing aspect differences on the steeper, lower mire, and the vegetation of gully floors, including oligotrophic mire centre vegetation and species-poor pools. The crests, though warmer, bore no special vegetation type.Mineral soil beneath the peat indicates a previous non-mire vegetation, which has subsequently paludified. Scarp slumps indicate downslope creep of organic material. Peat fissures, and mineral, vegetation, and erosion dams all appear to have initiated development of some pools.Mires are designated gully-head ribbon fens. Patterning appears to be accentuated because of the mires' gully-head location on broad-topped ranges, and drainage of soligenous water from upslope gully sides. These apparently unique fens give insight into patterning in aapa mires, and merit special conservation.

Question: What is the nature and relative importance of compositional gradients within‐ and between fens?Location: Iowa, USA.Methods: 506 0.5 m × 0.5 m quadrats were sampled from 31 fens across a 550 km extent. Presence/absence of all vascular plant taxa, plus the non‐vascular genera Sphagnum and Chara, and values for 24 environmental variables were noted. Global Non‐Metric Multidimensional Scaling and Monte Carlo tests were used to describe compositional variation and identify significant environmental co‐variables. Model‐based cluster analysis was used to identify the optimal number of groups supported by the data, while k‐means clustering was used to assign each quadrat to a group. The number of occurrences (and frequency) of each species within each group was calculated. Two‐dimensional 95% Gaussian confidence intervals, ANOVA, correlation coefficient homogeneity tests, log‐linear modelling, and Fisher's exact tests were used to document patterns of compositional change.Results: Two stable axes of variation were identified: the first being most closely correlated with soil pH, Mg, Ca, P, S, vegetation height, surface and −10 cm soil temperature, site area, perimeter, perimeter/area ratio, growing season, and air temperature, with the second being most correlated to soil moisture, N, disturbance level, % organic matter, hummock height, N‐S coordinate, and precipitation. Individual sites harboured between 20–47% of total compositional variation, with 28% of Axis 1 and 55% of Axis 2 scores being contained within‐sites. Five compositional regions were identified that differed in the proportion of calciphile and hydrophile species. Compositional groups differed significantly between geologic types.Conclusions: While the principal axis of variation (corresponding to the rich‐poor fen gradient) is present largely between sites, the second axis (corresponding to water level) is largely repeated within sites. Documentation and protection of vegetation patterns and species diversity within Iowa fens will thus require consideration of multiple sites across the landscape.
