An Assessment Of Wisalts Banks At Dangin, C J. Henschke, J A. Bessell-Browne

Resource management technical reports

This report compares two alternative approaches for the treatment and management of salt affected land at Dangin, Western Australia by determining whether there are benefits from a WISALTS bank system which would not accrue from standard soil conservation recommendations; comparing the costs and benefits of the two systems; and determining the nature of the effects of the two systems, particularly with respect to soil salinity.

A Description Of The Soils And Geology Of The Berkshire Valley Experimental Catchment, M R. Wells, D J. Mcfarlane

Resource management technical reports

Basic land resource data are provided in this report to assist an investigation of the effect of contour banking on surface runoff in the Berkshire Valley experimental catchement. Brief descriptions of the catchment's geology, soils and their inferred hydrological significance are provided and a 1:2000 scale map produced. Of major significance to the hydrologic study is the fact that soil depth and internal drainage conditions were found to be not related to landscape positions.

Residue Trials, Herbicide Incorporation And Leaching Of Chlorsulfuron, T Piper

Experimental Summaries - Plant Research

Residue Trials: Breakdown rates have been established for trifluralin at Wongan Hills and Avondale over the past two seasons. The decay curve follows a hyperbolic curve rather than the expected exponential curve with constant half life, probably due to the considerable loss of chemical by volatalization in the first few days, before biological decomposition takes over as the main breakdown factor.

b) Herbicide Incorporation. Du Pont Zl96 fluorescent orange powder at 30 g/m2 could be readily seen when illuminated by 400 yw/cm2 of 365 nm UV radiation, and was successfully photographed on Ektachrome 400 ASA film with a 4 sec. …

Annual Medics For The Kalgoorlie Region And Adjacent Eastern Rangeland Zones, G Gintzburger

Experimental Summaries - Plant Research

Species selection and establishment methods Extensive overgrazing and burning of the dominant winter rainfall Goldfields pastoral zones have left large areas degraded with a poor annual vegetation cover of nearly no grazing value. Thus, more grazing pressure is exerted on shrubs and small trees accelerating the desertification process. Shrubs and trees are the main stabilising agent left in a rangeland plant community when alI annuals have been grazed out. In order to upgrade or regenerate some of these areas, conventional methods of grazing prohibition or deferred grazing can be used but often, improvement obtained are slow. It is hypothesized that …

Curbur Station : Inventory Of The Range And Its Management, Alexander Mcrae Holm

Resource management technical reports

Ten land systems were identified, descriped and mapped. potential feed status was assessed for each land system. The land systems were then ranked accordingly and stocking rates allocated. Wongdong saline shrublands was considered to be the most productive system and Narryer hills, outcrops and breakaways the least productive. An assessment was made of the range condition and erosion status of the least. These assessments indicated that most of the pastures had been heavily utilized in the past.

Progress Report On Effects Of Contour Banking On Surface Runoff At The Berkshire Valley Experimental Catchment (Near Moora) 1961-82, K J. Bligh

Resource management technical reports

The time lag prior to peak runoff following rains of comparable high intensity increased by approximately 80 per cent in the largest event after the construction of contour banks. Although 80 per cent more runoff also occurred because the catchment was wetter and had been cultivated for three years in a row, the peak rate of runoff increased by only approximately 20 per cent. That the peak rate was not increased by 80 per cent, may be primarily attirbuted to the effect of the contour banks.

Western Australia continues to be one of the leading fishing States in Australia. The total gross value of fish, crustaceans and molluscs for 1980/81 was $82.8 million (Table 1) to which may be added the value of the pearl culture industry resulting in a total value of approximately $100 million.

Preliminary Groundwater Investigations In Relation To Soil Salinity At Fitzgerald, Western Australia, C J. Henschke

Resource management technical reports

This study investigated soil salinity problems in relation to new land releases at Fitzgerald near the south coast of Western Australia. Fairly widely spaced set of bores was established to compare the groundwater hydrology regimes beneath cleared and virgin land. A large storage of soluble salts (over 100 kgm-2 in some profiles) was measured in the pallid zone clays under both cleared and virgin land conditions. Seasonal fresh to brackish perched watertables were found to overlie highly saline deep waterbles at a number of valley sites on land which has been cleared for agriculture during the past 15 years. Salinity …

A further 128 angiosperms are listed with geographical ranges between 100 and 160 kilometres. No fern or gymnosperm species in the region are known to be geographically restricted.

Apart from the presently unnamed species, a large majority of the rare plants of southern Western Australia are believed to be listed, including 86 of the species that have been gazetted as rare flora.

Fishery Report No 55 - The Western Rock Lobster Fishery 1961 - 1971, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster, Panulinus cygnus is one of the most important single fisheries in Australia and one of the major rock lobster fisheries of the world with catches in recent years averaging some 8000 tonnes annually. The history of the commercial fishery extends back to 1944/45 factory when a canning was opened at the Abrolhos Islands (Figure 1) with a view to supplying the Australian armed forces. After the World war, an export market for fresh frozen rock lobster tails was quickly established in the U.S.A. and the industry, sharing in the advantages of postwar reconstruction, …

A Japanese demersal trawler, 'Taiyo Maru 771' was given special permission to conduct exploratory trawling in the period 73.7.79-16.9.79 off the Western Australian coast between 21°S Latitude and 35°30'S Latitude, an area which partly overlapped the fishing grounds for the western rock Lobster. The vessel was required to complete a catch, fishing effort and species composition log book issued by the Commonweath Department of Primary Industry. Two Western Australian Department of Fisheries and Wildlife observers on board monitored fishing operations for the entire duration of the cause and undertook research.

Fisheries Report No 57 - Exploratory Fishing For Spanish Mackerel In Waters Off Western Australia During The Period June 16 To October 16, 1981, K. Donohue, P. Edsall, J. Robins, R. Tregonning

Fisheries Research Reports

The results of catching Spanish mackerel (Scomberomorus commerson) by gillnet and troll lines during a survey extending from June 16 to October 16 1981 are presented.

The catch rate of mackerel obtained by trolling with six lines was found to be 14.35 times greater than that by gillnet, measuring 0.75 miles in length.

From the results presented, a professional fisherman should be able to assess the economic viability of fishing commercially for Spanish mackerel.

Analysis of biometrial and biological data on fish caught allowed determination of (a) length/weight relationship of (i) Spanish mackerel (ii) wahoo (Acanthocybium solandri); (b) sex ratios …
