“…Similar soils have been reported in other studies (Teakle, 1938;Mulcahy and Hingston, 1961;Stephens, 1961;Bettenay, 1962;Burvill, 1988), as have soils with ferricrete gravels overlying strongly alkaline subsoils, again with calcareous nodules (Teakle, 1938).…”

“…The illite may have formed authigenically in the playa floor or sub-surface brines. A similar proposal was made by Bettenay (1962), however, he reported dust as occurring in discrete layers, a situation that does not occur in the Cairlocup area, possibly because of the smaller area of the source playa compared to that at Merredin, where the source is several kilometres wide. Small additions of dust, without the formation of discrete layers, is consistent with observations elsewhere (Yaalon and Ganor, 1973;Tsoar and Pye, 1987).…”

“…Aeolian features reported in southwestern Australia include clayey and sandy saltation deposits (lunettes), which occur adjacent to playas (Stephens and Crocker, 1946), clayey deposits (lake parna) downwind of playas (Bettenay, 1962), gypseous lunettes (de la Hunty and Low, 1958;Bettenay, 1962;Jones, 1994), source-bordering sand dune systems adjacent to ephemeral stream lines (Beard, 1982(Beard, , 1984 and aeolian dusts that occur in ferricrete horizons in deeply weathered profiles (Brimhall et al, 1988). The latter was inferred from the occurrence of rounded rutile and zircon in surface ferricrete horizons, whereas these minerals are absent from underlying bedrock.…”

“…As playa shapes form in response to wind-driven currents, they have been used to infer the orientation of winds during lake full conditions (Price, 1972;Killigrew and Gilkes, 1974;Marrs and Gaylord, 1982). Deflation from playas is a major process, with playas often being fringed by deposits of material deflated from the playa surface, such as lunettes (Stephens and Crocker, 1946;Bettenay, 1962;Bowler, 1973) and extensive deposits of lake parna (Bettenay, 1962).…”

“…On the downwind edges of many playas and pans material transported from the lake floor forms berms and low flats of gypsum, clay and sand (Bettenay, 1962). Gypsum deposits occur within inland saline playas and coastal barred basins, where brines are concentrated and evaporites formed (Jones, 1994).…”

-Eight hundred and thirteen quad rats were surveyed to sample wetland vegetation throughout the wheatbelt and adjacent south coast of Western Australia, an area of ca. 220 000 km 2 . Two hundred and fourteen wetlands were intensively sampled with between one and ten quad rats placed at each wetland to capture the major vegetation zonation. A further 100 quadrats were scattered through the study area to sample particular examples of wet land vegetation. Sampling spanned the full range of elevations at wetlands from inundated basins to the adjacent landforms such as lunettes.A total of 1436 taxa of vascular plants from 109 families were recorded. Naturalized taxa were 11.8% of the flora. Four hundred and twenty-eight taxa (29.7%) were categorized as restricted to wetland habitats. These included both aquatic (53 taxa) and amphibious plants (89 taxa). The wetlands of the study area represent the world centre of diversity for annual Juncaginaceae and the subfamily Salicornioideae (Chenopodiaceae).Species richness of quadrats (100 01 2 ) ranged from 1-72 taxa, with a mean of 20.5 taxa per quadrat. Thirty-one per cent of taxa only occurred at a single quadrat (singletons) and 59.3% occurred at less than five quadrats. Eight previously unrecognized taxa were collected for the first time and the habitats and distributions of several undescribed taxa with few previous collections were clarified. Collections were made of 78 taxa listed on the Department of Conservation and Land Management's priority flora list. Eight of these were gazetted as Declared Rare Flora (Wildlife Conservation Act, 1950) with two (Frnnkenia conferta and F. parvL/la) regarded as extinct prior to the current survey.Detailed cluster analysis was conducted on a reduced dataset (980 taxa by 760 quad rats) that excluded singleton species and some species-poor quad rats. A classification of 26 quad rat groups was defined. The primary division in the quad rat classification separated quad rats of inland largely naturally saline wetlands from quad rats at non-saline wetlands and at various wet land types with coastal and southwestern distributions. Lower levels in the classification were strongly related to local elevation and edaphic attributes of quadrats.Thirty-four assemblages were defined from species cluster analysis and 29 were regarded as coherent species groups. The richness patterns of assemblages were modeled against 34 environmental attributes. Models explained between 26% and 74'Yo of total deviance. Modeling was complicated by some assemblages having few members. Of the parameters used in the modeling, elevation at wetlands, substrate, electrical conductivity and pH were the dominant variables of models with the greatest decrease in deviance. Most assemblages were geographically well defined with annual precipitation and annual temperature range being important regional scalars.Fifteen plant assemblages containing 472 native taxa are identified as being at particular risk from secondary salinisation. They include assemblages of both ...
