“…The ferns Histiopteris incisa and Dicranopteris linearis were an occasional component, with the groundcover a dense bryophyte turf of mixtures ofTelaranea praenitens, Lepidozia laevifolia, and Dicranum robustum. This is similar to zones 4 and 5 of Given (1980) at Karapiti.…”

“…In response to these stressed conditions, a distinctive vegetation occurs on geothermal areas in the Taupo Volcanic Zone of New Zealand (Given 1980;Healy 1992), where 39 'islands' of naturally thermotolerant vegetation, totalling about 580 ha, are scattered over some 20 000 km 2 . Geothermal systems are important for energy extraction, tourism, and conservation.…”

Naturally thermotolerant vegetation in New Zealand is concentrated in approximately 39 geothermally heated areas totalling only 580 ha scattered along the 300 km length of the Taupo Volcanic Zone. Relationships between composition and structure of vegetation and environment were analysed at the comparatively large (95 ha) and unmodified Te Kopia geothermal steamfield. Vascular vegetation was mostly influenced by a strong gradient in soil temperature, ranging at 15 cm depth from 15°C to 90°C across the steamfield. Dominant species changed from evergreen, broadleaved forest at the cool end of this gradient to dominance on increasingly hot soils by myrtaceous and epacrid (southern heath) shrubs with small needle-like leaves and shallow roots. While differences in cryptogam composition were mostly associated with spatial variation in soil temperature, they were also significantly influenced by soil acidity and Al concentration. All soils sampled along the gradient had low fertility, high acidity, and high levels of Al, SO 4 , and Fe. This suggests that vegetation considered to be geothermally influenced should include relatively tall forest and scrub further from fumarole centres than has previously been recognised.Plants of geothermal areas tolerate acid soils with levels of Al that normally would be toxic. Mycorrhizal relationships may play important roles in plant survivorship in this environment by assisting nutrient acquisition. In common with the changes in community characteristics typical of other steep gradients of increasing stress, as soil temperatures increase so canopy height, plant stature, species richness, leaf size, and rooting depth decrease. These distinctive ecosystems provide excellent opportunities for research on plant community response to natural stress.

Samples of six common plant species collected in the old mining areas near Prince George, British Columbia (Canada) and Mount Amiata, Tuscany (Italy) show remarkable similarities in the variation of plant/soil Hg concentration ratio with soil Hg content irrespective of species or other biological differences. In contrast, plants sampled in the geothermally active areas of New Zealand, Hawaii and around Mount St. Helens exhibit more individuality in the concentration ratio to soil Hg relationship, but the relationships are distinctly different from the mine site specimens. This distinction is particularly evident when the same species of Equisetum and Plantago taken from these two different areas are compared. These and other data support the hypothesis that specific local environmental factors strongly influence the accumulation of Hg in plants even when the immediate soil concentrations are the same. Our findings show that some plants contain concentrations of total Hg as high as 5500 to 14000 Ixg kg-~ (dw). Experimental STUDY SITES AND PLANTSThe Cominco Hg mine at Fort St. James and the nearby city of Prince George have been described (Johnston et aL, 1975;
