Woodchipping River Red Gum logs, Murrumbidgee River, Australia. The trees only grow on the river floodplains and old trees with hollows are important duck and waterbird nesting sites. Logging of these old trees is a conservation concern. S66.23s

Flood irrigation of rice paddies in the Murrumbidgee Irrigation Area of Australia. Intensive irrigation schemes and mechanised farming has made Australian rice production competitive with the more labour intensive Asian production, but large scale irrigation has caused salinity problems in the Australian environment. S15.10s, S22.6s

Spraying a chemical cocktail of fertiliser, pesticide and/or herbicide for planting another broadacre crop, Darling Downs, Qld, Australia. Intensive agriculture feeds & clothes the community, & provides foreign exchange, but needs careful management to maintain environmental health, protect product quality and public health, and ensure sustainability.S98.5s

Loss of top soil and resultant colluvium on farmland by imprudent ploughing on a slope followed by heavy rainfall, western Darling Downs, Sth Qld., Australia. The precious top soil resource, source of all agricultural prosperity, then becomes a silting problem in watercourses. S98.19s

Sheet erosion beside the Balonne River, SW Qld, Australia. Excessively intensive land use, perhaps overgrazing, has damaged the protective layer of top-soil, allowing rains and wind to scour subsoil and undermine even large trees.6x9cm SW21.8e	Soil testing using a core sampler which presses a cylindrical corer up to 2m into the soil. The extracted core is laid out, colour, texture, structure and chemical properties are recorded to classify the soil. Technician is measuring the pH of a soil sample.This crew working wallum country in Miriam Vale shire, coastal Qld, Australia. CQ50.6s	Dates, fruit of the date palm Phoenix dactylifera, probably originating in Nth Africa but cultivated in hot, dry areas worldwide eg. Eulo, west Qld, Australia, for table fruit and now wine. Each tree can bear 50kg of dates, for over 100years, but are eaten by Bowerbirds which presents a wildlife pest management problem. S103.16	Gully erosion caused by the clearing of tree cover on erodable soils Central Victoria, Australia. Land degradation is a major global problem, particularly in tropical and semi-arid lands with easily erodable soils and episodic rainfall. S5.1s	Volunteer rural firefighters in one of 1000's of Rural Bush Fire Brigades in Australia(1600 in Qld), man their ancient but well-maintained firetruck. Land of extremes, few nations are so reliant on volunteers (both Rural Fire Brigades and State Emergency Services) as Australia for internal safety. S101.20
Stockman tends cattle in rich grazing pasture on the floodplain of the Macintyre River, part of the great Murray-Darling river system of inland Australia, source of much of the nation's pastoral wealth, but now needing landcare. S103.19	Historic steam engine used to pump water from Paroo River on Currawinya Station (now Currawinya NP), outback SW Qld, Australia for stock and fodder crop irrigation. Reminder of pioneer pastoral industry on park now preserving internationally important wildlife. S98.15s	Planting out Paulownia seedings in a silvicultural nusery near Rosedale, Qld, Australia. Chinese Paulownia trees produce light, easily worked timber in short growing periods, but require irrigation and fertilisation. The native versus exotic forestry question continues: exotics often need more water, may become feral, and generally displace wildlife habitat. CQ45.4s	Loading sunflower seeds for transport to markets in the Emerald irrigation area, central Queensland, Australia. Used mainly for vegetable oil, sunflowers are a cash crops produced with water from the Fairbairn Dam, but care is needed with irrigation to ensure saline water tables don’t rise. CQ30.1s	Wind and water sheet erosion leaves a stunted River Red Gum Eucalyptus camaldulensis supported by its exposed roots on the shore of Lake Tongo, a desert overflow lake at the end of the Paroo River, outback Australia. S18.2s
Landcare and Catchment Management volunteer plants a tree on the damaged bank of Baffle Creek, Queensland, Australia. Streambank stabilisation is one of the many uses of vegetation restoration after construction or erosion, and controls sedimentation of nearby waterways. Landcare and Integrated Catchment Management are widespread community-based natural resource management movements which recognise the need for increased stewardship of the land. CQ42.12s
