How To Reduce Spending On Land Conservation, Tim Negus

Journal of the Department of Agriculture, Western Australia, Series 4

Heavy spending on capital works for land conseroation is usually out of the question in the present financial climate, but the recession does not mean that landcare must be abandoned. There are many aspects of landcare that involve little or no extra cost. Soil conseroationist Tim Negus discusses them in this article.

The Role Of Earthworms In Western Australian Agriculture, Tom Mccredie, Lex Parker

Journal of the Department of Agriculture, Western Australia, Series 4

Earthworms have a reputation as soil builders and renovators, particularly among 'organic' farmers and gardeners. They improve soil fertility through increased aeration, aggregation, water infiltration and release of nutrients from organic matter. However, the benefits of earthworms in the wheatbelt have been doubted for many years because of their poor survival in cultivated soils.

Since cropping began in the Western Auslmlian whealbelt over 1OO years ago, the physical condition of many soils has deteriorated. The primary causes of soil degradation were the European cultivation practices used by farmers and the trampling effect of introduced animals. in particular, sheep.

The rangelands of Western Australia lie to the north-west of the agricultural areas, extending east to the Nullarbor and north to the Kimberley (Fig. 1). The major areas that are used for pastoralism are most of the Kimberley and the Pilbara, nearly all of the mulga shrublands, plus some of the Goldfields gum belt and part of the Nullarbor Plain.

Fisheries Research Report No 91 - A Synopsis Of The Biology And The Exploitation Of The Australasian Pilchard, Sardinops Neopilchardus (Steindachner) Part Ii: History Of Stock Assessment And Exploitation, W. J. Fletcher

Fisheries Research Reports

This report summarises the studies which have provided information on the population characteristics and exploitation of the pilchard, Sardinops neopilchardus in Australia and New Zealand. This review was undertaken to determine whether existing data could be used to assess the status of Western Australian or other stocks or, alternatively, what additional information was required.

The mean size of pilchards caught varies among locations but, in general, fish are between 140 and 160 mm LCF, corresponding to ages 2 - 5 years. The length-weight relationship also varies between locations

Attempts to initiate pilchard fisheries have been hampered by the lack of …

Survey Of The Damage Caused To Trees By Goats, Steve Gherardi, Dick Mills, Tim Johnson

Journal of the Department of Agriculture, Western Australia, Series 4

The damage that goats can cause to trees is one of the major problems associated with their farming in the agricultural areas of Australia. It is also considered one of the main hindrances to the development of the goat industry. The Department of Agriculture s Goat Industry Development Unit surveyed mohair and cashmere producers to determine the prevalence of tree damage and its extent and severity; why producers believed goats damaged trees; and how producers minimised or prevented this damage.

Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace

Journal of the Department of Agriculture, Western Australia, Series 4

Retention of native vegetation on farms is important both from an ecological and an economic point of view. Productivity in the paddocks ultimately will depend on the retention and replacement of trees and shrubs in the landscape. Remnants of native vegetation can play their part by helping to ensure the long-term viability of the agricultural system, as well as greatly enhancing the quality of life for those living on the land.

G91-1025 Two Crops In One Year: Doublecropping, Russell Moomaw, Gary Lesoing, Charles A. Francis

University of Nebraska-Lincoln Extension: Historical Materials

Choice of crops, weed control, and other cultural practices for successful doublecropping are discussed here. Multiple cropping refers to growing two crops on the same field during the same year. One method of multiple cropping is doublecropping, which is when one crop is grown after the first crop is harvested. Prime USA regions for doublecropping are the eastern cornbelt, and southeastern and south central states where relatively long growing seasons and abundant rainfall occur. By contrast, shorter growing seasons and less frequent rainfall limit the potential for doublecropping in Nebraska. Irrigation is essential for successful doublecropping in Nebraska. Without irrigation, …

El Papel De Las Mujeres En La Conservación De Los Bosques Del Nepal, Augusta Molnar

Poverty, Gender, and Youth

Este número de SEEDS pone de relieve las formas en que se ha hecho participar a las mujeres en un programa gubernamental de conservación y restauración de bosques en Nepal. Como en muchos proyectos de gran escala e impacto generalizado, las mujeres no tenían un papel específico en el diseño original del proyecto. Pero una vez que comenzaron las actividades, tanto el personal nepales como sus colegas extranjeros tuvieron que reconocer que para que la estrategía participative pudiera funcionar, era esencial contar con las mujeres. De ahí que durante los primeros cinco anos del proyecto (1980–85) se probaron varias maneras …

Fisheries Research Report No. 89 - Relationships Among Partial And Whole Lengths And Weights For Western Australian Pink Snapper Chrysophrys Auratus (Sparidae), M. J. Moran, C. Burton

Fisheries Research Reports

Pink snapper, Chrysophrysauratus (Sparidae) is one of the major commercial and recreational fish in Western Australian inshore waters. This report presents a number of equations and conversion factors for management and scientific study of the species. Equations to calculate total lengths from partial lengths will facilitate enforcement of minimum legal lengths when snapper are landed in a "head-off" condition. For fisheries science purposes, there are equations to convert among total length, standard length and length to caudal fork; and to convert lengths and weights of processed fish to whole lengths and weights. Length-weight relationships are presented and compared with those …

Fisheries Research Report No 88 - A Synopsis Of The Biology And The Exploitation Of The Australiasian Pilchard, Sardinops Neopilchardus (Steindachner) Part 1: Biology, W. J. Fletcher

Fisheries Research Reports

There have been a large number of studies which relate to the biology and exploitation of the Australian pilchard, Sardinops neopilchardus. Much of the data, however, are located in journals which are hard to obtain, or in unpublished reports, and theses. With the increase in catch of pil­chards, particularly in Western Australia, a collation of all the available knowledge pertaining to pilchards in Australia and New Zealand was desired to help with the planning of future research into the Western Australian stocks of this species. This report contains all the information located on the biology of Sardinops neopilchardus, a companion …

Fisheries Research Report No 99 - An Investigation Of Weight Loss Of Marron (Cherax Tenuimanus) In Air During Live Transport To Market, Noel Morrissy, Peter Walker, Cliff Fellows, Warren Moore

Fisheries Research Reports

It is generally acknowledged that more competitive marketing of Australian fisheries and aquaculture harvests requires closer attention to post-harvest technology. Historically, these products have been marketed in a variety of forms (e.g., for freshwater crayfish:- boiled fresh, boiled frozen, whole or tails, and live). Some of these forms present a product of actual, or perceived, poorer quality to the retailer and consumer and, thereby, obtain low prices.

Freshwater crayfish can survive out of water for extended periods and, so, can be economically transported alive to the (overseas) restaurant chef. This live product commands the very highest price for the grower. …

Hawaii's Rainforest Crunch: Land, People, And Geothermal Development, Paul Faulstich

Pitzer Faculty Publications and Research

One hundred and forty-one people, led by Native Hawaiians, were arrested on 25 March 1990 as part of the largest demonstration yet against geothermal development in Hawaii. The gathering was intended to focus attention on Native Hawaiian rights and the ecological consequences of drilling geothermal wells in the near-pristine Wao Kele O Puna rain forest. The energy project, undertaken by True Geothermal Company and endorsed by Hawaii's governor and other imposing figures, has already invaded the largest intact tropical lowland rain forest in the United States.

Fisheries Research Report No. 87 - The Recreational Marron Fishery In Western Australia, Summarised Research Statistics, 1971-1987, N. M. Morrissy, C. J. Fellows

Fisheries Research Reports

The freshwater crayfish Cherax tenuimanus, called marron, provides an important recreational fishery in the south-west of Western Australia. The annual fishing catch and fishing effort have been monitored by a log book research programme and an end-of season telephone survey since the 1971/72 season.

Following the 1986/87 fishing season, the fishery remained closed for two seasons (1987/88 and 1988/89) to permit stocks to recover from the effects of high total fishing effort and unfavourable water conditions over the preceding seasons

This paper provides a detailed account of the catch and effort statistics to the close of the 1986/87 fishing season, …

Fisheries Research Report No. 92 - Spread Of The Introduced Yabbie Cherax Albidus Clark, 1936 In Western Australia, N. M. Morrissy, G. Cassells

Fisheries Research Reports

This report presents information on the probable original introduction of the eastern Australian yabbie to farm dams in the Wheat-belt Region of the southwest of Western Australia (in 1932 at Narembeen); the probable type of yabbie (the "White Yabby", Cherax albidus Clark 1936 ) and source (Miram Swamp in the Victorian Wimmera); and, in 1985, the first voicing of concern over the spread of yabbies to natural habitats, particularly in the higher rainfall region of the southwest, together with current national and international concerns and advice on introduced aquatic species.

Fisheries Research Report No. 83 - The Western Rock Lobster Fishery 1985/86, R. S. Brown, E H. Barker

Fisheries Research Reports

The 1985/86 annual catch of the western rock lobster Panulirus cygnus, totalled 7,191,968kg (Australian Bureau of Statistics (ABS) ), a drop of 1,774,497kg (19.8 per cent) on the 1984/85 season. The value of the 1985/86 catch was approximately $94M based on ABS figures. This drop in catch was almost entirely the result of lower puerulus (first post larval stage, approximately 9 to 11 months old) settlement three to four years before (i.e. 1982/83 and 1981/82). The fall in catch was accompanied by a drop in fishing effort (total number of pot lifts) of 12.1 per cent on the previous season …

Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson

Journal of the Department of Agriculture, Western Australia, Series 4

One of the more difficult aspects of growing potatoes in Western Australia is controlling soil insect pests. These pests have become more troublesome because the highly effective and persistent organochlorine insecticides previously used to control the main soil pests, African black beetle and whitefringed weevil, were deregistered for agricultural use in 1987. Entomologists from the Department of Agriculture and CSIRO in Western Australia are collaborating to develop new management strategies for these pests that rely less on the use of chemical insecticides
