“…Evidence of this increase is seen in the current spread of Artemia parthenogenetica into salt lakes of the area (McMaster et al, 2007). An additional consequence of highly saline surface flow entering lakes may be the loss of the 'fresher' end of the inundation cycle (5-30 g l -1 ), particularly in small pans following heavy rainfall events when there are large influxes of rainwater in a short time interval, thereby eliminating a range of ecological niches that are created following rainfall.…”

Salt lakes of the northern agricultural region, Western Australia

A survey of 11 sites covering three large (>10 km long, 6 sites) playa lakes and four pans ( < 1 km 2 , 5 sites) of the Yarra Yarra salt lake system in the Northern Agricultural Region of Western Australia commenced in 2001. These salt lakes are shallow and ephemeral, with inundation being more regular following winter rainfall, but summer inundation also occurred in 2001. Salinity was generally higher in playas (156-368 g l -1 ) than pans (30-284 g l -1 ), but salinity responded noticeably to heavy rainfall events, especially in pans. pH values in the playa lakes (6.68-7.82) were less variable than in the pans (6.81-8.08). The range of dissolved oxygen concentrations was greater in pans (3.7-14.4 mg l -1 ) than in playas (3.9-8.2 mg l -1 ). Cationic concentrations generally followed the pattern of sea water cation dominance. Benthic microbial communities comprised either cohesive to loosely mucilaginous mats, or thin films of diatoms. Five genera of diatom and two species of filamentous cyanobacteria were recorded.

“…Williams, 1981). However Geddes (1979) opines that it is remotely possible those in coastal WA spread there naturally from Asia, a view supported and expanded by McMaster et al (2007). At least two species are present in Australia ---a sexual species in the Rockhampton, Bowen, Dry Creek (Adelaide), Port Hedland and Dampier saltworks that is probably A. franciscana (M.

“…More recently, the view that Artemia spread by natural means from Asia has gained wide support (e.g., McMaster et al 2007;Timms 2004). The spread of Artemia into natural waterways where they will likely co-occur with native anostracans is of concern.…”

Secondary salinisation is recognised worldwide as a threat to aquatic biodiversity. Wetlands in the Wheatbelt Region of Western Australia are particularly affected as a result of clearing of deeprooted native vegetation for agriculture. Between 1996 and 2001, the Western Australian government nominated six natural diversity recovery catchments (NDRCs), being catchments with high value and diverse wetlands in need of protection. One, the BuntineMarchagee NDRC, supports approximately 1000 wetlands in varying states of salinisation. The challenge is to prioritise these wetlands for ongoing management. In this paper we propose an approach to prioritise representative wetlands using aquatic invertebrates. On the basis of hydrology, salinity and remnant vegetation, 20 wetlands covering a range of salinities were selected for sampling of water quality and aquatic invertebrates. Of the 202 taxa recorded, most endemic taxa occurred in fresh/brackish wetlands, while hypersaline wetlands supported predominantly cosmopolitan species. Taxa richness was greater in fresh/brackish than saline and hypersaline wetlands, with conductivity explaining 83 % of between-wetland variation in taxa richness. Classification using invertebrate assemblages separated fresh/brackish, saline and hypersaline wetlands, with greatest between-year variability within saline and hypersaline sites. Wetlands were ranked using taxa diversity, presence of conservation-significant taxa and temporal similarity. Mean rank across indices provided the final overall order of priority. Hypersaline wetlands were ordered separately to the fresher water wetlands (fresh/brackish and saline) so that priority for future management was detailed for both types of wetlands. The analysis indicated that although fresh/brackish sites support the highest biodiversity, naturally saline sites also supported wetland assemblages worthy of ongoing protection.
