This interactive guide has been produced as a tool for assessing pasture condition over a range of pasture types in the Kimberley. A pasture type is a distinctive mix of plant species, soil type and landscape position. For example, the Mitchell Grass Alluvial Plain Pasture type is a mixture of Mitchell grasses and other species occurring on black soil alluvial plains. Pasture condition is an important factor affecting the potential of the rangelands for animal production and is a useful indicator for the sustainability of production.
James’S Rule And Causes And Consequences Of A Latitudinal Cline In The Demography Of John’S Snapper (Lutjanus Johnii) In Coastal Waters Of Australia, Mike Cappo, Ross J. Marriott, Stephen J. Newman
James’S Rule And Causes And Consequences Of A Latitudinal Cline In The Demography Of John’S Snapper (Lutjanus Johnii) In Coastal Waters Of Australia, Mike Cappo, Ross J. Marriott, Stephen J. Newman
Fisheries Research Articles
Demographic parameters were derived from sectioned otoliths of John’s Snapper (Lutjanus johnii) from 4 regions across 9° of latitude and 23° of longitude in northern Australia. Latitudinal variation in size and growth rates of this species greatly exceeded longitudinal variation. Populations of John’s Snapper farthest from the equator had the largest body sizes, in line with James’s rule, and the fastest growth rates, contrary to the temperature size rule for ectotherms. A maximum age of 28.6 years, nearly 3 times previous estimates, was recorded and the largest individual was 990 mm in fork length. Females grew to a larger mean …
Report To The Commissioner Of Soil And Land Conservation On The Condition Of The Western Australian Pastoral Resource Base 2013, Paul Novelly, Philip Thomas
Report To The Commissioner Of Soil And Land Conservation On The Condition Of The Western Australian Pastoral Resource Base 2013, Paul Novelly, Philip Thomas
Natural resources published reports
This report updates changes in the Western Australian pastoral rangelands at the Land Conservation District (LCD) scale, providing information on seasonal quality, stock numbers and changes in the density/frequency of perennial shrubs and grasses. It is based on data from the Bureau of Meteorology, the Annual return of livestock and improvements (submitted annually by pastoral lessees) and the Western Australian Rangeland Monitoring System (WARMS). The sixth assessment of the Kimberley grassland sites (Epoch 6) was completed in 2011. The second full cycle (i.e. 3 assessments) was completed for shrubland sites in 2010. This report includes the most recently collected data …

A Review Of The Broome Sandstone Aquifer In The La Grange Area, Robert J. Paul, Richard J. George Dr, Peter Gardiner
Resource management technical reports
Land use in the West Kimberley near Broome, Western Australia, is dominated by cattle grazing on pastoral stations, dispersed mining activity and tourism. Irrigated agriculture has developed but is at a small scale. There is interest from pastoralists and horticultural companies to expand irrigated agriculture, and pastoral diversification and mosaic irrigation systems have been proposed. However, if irrigated agriculture is to expand, it must be viable and meet community and regulatory requirements. Developing secure and sustainable water resources is critical
This review is focussed on the La Grange groundwater subareas (La Grange area). Its purpose is to summarise the existing …
