Pasture Condition Guides For The Southern Rangelands, Including The Gascoyne, Murchison And Goldfields-Nullarbor, Peter-Jon A. Waddell, Philip We Thomas, Wayne J. Fletcher, Kath Ryan, Joshua E. Foster, John K. Stretch, Jim S. Addison

Bulletins 4000 -

These guides address a recognised gap in readily applicable and easily accessible information on southern rangelands pasture condition and management.

These guides provide descriptions and images for southern rangelands pastures with similar management requirements for the grazing of native pastures by livestock. Therefore, the focus is on palatability of vegetation to livestock, and the effects of livestock management and external factors on the condition of the vegetation and soils.

The first section provides an overview and map, introduces concepts and terms important to understanding arid shrubland management in general, these guides in particular; and includes an economic analysis of the …

Bioenergy And Carbon Farming Opportunities In The Pilbara, Robert Sudmeyer, Kim Brooksbank, David Rogers

Bulletins 4000 -

The Pilbara region covers 270 000 square kilometres of north-west Western Australia. Its main agricultural land use is pastoralism, with beef cattle grazing native pastures. Currently, only 24km² is under irrigation, with irrigated fodder the principal crop, but this could expand to 100km². This expansion has the potential to significantly broaden the economic base of the Pilbara.

Irrigation and the opportunities for changing land use and management may facilitate greater participation in the carbon economy by Pilbara land managers. Bioenergy feedstocks could be sourced from purpose-grown crops or agricultural wastes. Carbon farming activities may be facilitated by …

Agricultural Greenhouse Gas Emissions, Meredith Fairbanks, David Bowran, Geraldine Pasqual

Bulletins 4000 -

Agriculture contributes 15.5 per cent of Australia’s emissions (Figure 1), largely due to methane, from ruminant livestock digestion, nitrous oxide from soils and carbon dioxide from fossil fuel use (Australian National Greenhouse Accounts 2011; ABARES 2011).

This bulletin identifies current ways to reduce greenhouse gas emissions from Australian agriculture.

Carbon Capture Project, Final Report. An Evaluation Of The Opportunity And Risks Of Carbon Offset Based Enterprises In The Kimberley-Pilbara Region Of Western Australia, Mark Alchin, Elizabeth Tierney, Chris Chilcott

Bulletins 4000 -

Commercialisation of carbon in the Australian Rangelands could lead to the development of a multi-billion dollar industry, and Western Australia has the potential to capture a significant share of this revenue. A significant proportion of the WA Rangelands is degraded which is the legacy of the exploitative practices of historical pastoral development and the mining industry. Full environmental restoration of these areas is well beyond the fiscal capacity of land managers and the WA State Government. Carbon based enterprises have the potential to restore large tracts of degraded land in a cost-effective manner and can deliver a number of other …

Environmental Guidelines For New And Existing Piggeries, A Latto, John Noonan, R. J. Taylor

Bulletins 4000 -

These guidelines apply to the management of Western Australia piggeries in Western Australia, including intensive Growing pigs under intensive conditions where the and extensive operations, straw-based housing and animals spend their entire life cycle indoors, is an combinations of these (otherwise referred to as semi- important part of the Western Australian and intensive housing).

Selecting And Developing Reliable Bore Sites In The Eastern Wheatbelt, Richard George

Bulletins 4000 -

In the Western Australian wheatbelt, groundwater supplies contribute about 40 per cent of the on-farm livestock requirements and occasionally domestic water supply systems. The first part of this Bulletin comments on sites suitable for both high yielding bores and also those which yield water suitable for livestock. The second part outlines techniques for constructing and developing a bore. Throughout this Bulletin livestock quality water, for adult sheep, is defined as groundwater of less than 12,000 mg/L (or 850 grains per gallon) which has not been subject to localized pollution. For other livestock, the maximum salinities range from 2,600 mg/L for …
