Abstract

The Lake Ewart region is highly varied geologically and topographically. It lies within a biologically poorly known and remote part of Tasmania. Eldon Bluff, a high dolerite plateau, is largely covered by mosaic bolster heath within which have formed shallow peat ponds similar to those at Newdegate Pass. Dome Hill, topped by fissile mudstones, has stone stripes similar to those recorded for the fjaeldmarks of Pyramid Hill. Subalpine scrub and forest is largely dominated by Eucalyptus coccifera and E. subcrenuata, although E. nitida is important on quartzite. There are small areas of Athrotaxis cupressoides woodland and rainforest dominated by Nothofagus cunninghamii. The treeless subalpine vegetation consists of a mixture of short herbfield, Sphagnum bog and tussock sedgeland on the more fertile substrates, while heathy sedgeland and scrub predominate on more siliceous soils.
