Nutrient Limitation In A Southwestern Desert Reservoir: Eutrophication Of Las Vegas Bay, Lake Mead, Nevada, Davine M. Lieberman
Publications (WR)
Algal bioassay tests were conducted with Selenastrum capricornutum and natural algae on inner Las Vegas Bay, Lake Mead, Nevada, from December 1992 through September 1993, to identify any nutrient limitation in an area of the reservoir that has experienced problems associated with severe nutrient enrichment. Three areas were sampled based on a gradient of water quality conditions that existed in Las Vegas Bay (LVB). Disodium ethylenedinitrilotetraacetate (EDTA) significantly stimulated algal growth compared to non-EDTA treatment. Algal bioassays indicated that phosphorus (P) was the primary limiting nutrient at all stations for most of the test dates. Chl a response with EDTA …

Resource management technical reports
Remnant vegetation mapping and its incorporation into a Geographical Information System (GIS) data base is the first stage in an overall documentation and promotion of conservation of remnant vegetation in Western Australia. The primary objective of this project being to determine the amount, distribution and regional location of native vegetation remaining on private land in the agricultural area of south-west Western Australia.

Land resources series
This survey of the Bencubbin area is part of the Agriculture Western Australia's regional land resource mapping program, and covers approximately 1.5 million hectares in the Merredin, Trayning, Koorda, Mount Marshall, Mukinbudin, Westonia and Nungarin Shires of Western Australia. The climate is Mediterranean, with hot dry summers and cool winters. Land is used for winter cereal production and grazing, and about 60% is cropped each year. Wheat is the main crop and is grown in rotation with lupins, field peas, barley and medic pasture. This report provides primary and interpreted information on the character and capability of the land, for …
