Plans For Crash-Tested Bridge Railings For Longitudinal Wood Decks, Michael A. Ritter, Ronald K. Faller, Paula D. Hilbrich Lee, Barry Thomas Rosson, Sheila Rimal Duwadi

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

In the past decade, bridge railing design criteria have moved away from static-load design and have focused on full-scale crash testing as a more appropriate and reliable means of evaluating bridge railings. The five bridge railing plans presented reflect the results of a cooperative research project between the Midwest Roadside Safety Facility, University of Nebraska-Lincoln; the USDA Forest Service, Forest Products Laboraotry; and the Federal Highway Administration. The project objective was to develop and crash test bridge railings and approach railing transitions for longitudinal wood bridge decks. The bridge railings were completed in accordance with AASHTO Performance Levell, Performance Level …


Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt Mar 1995

Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt

Natural resources published reports

Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George Jan 1993

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …


Windbreaks Prove Their Worth, Tim Negus Jan 1991

Windbreaks Prove Their Worth, Tim Negus

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

Strong winds in the south-west of Western Australia in April 1991 carted tonnes of top soil from stubbles, over-grazed pastures, and recently prepared cropping land. However, where there were windbreaks, downwind protection into the paddock was up to 10 to 20 times the height of the windbreaks. On May 1, 1991, the author inspected farm land for damage from Narrogin to the Dongolocking area, to Harrismith, up the rabbit-proof fence to West Corrigin and back to Narrogin via Kweda. He found the extent of soil erosion varied, and that some tree species planted in windbreaks gave better protection than others


Whole-Farm Planning : Success At Wilgi Creek, Kevin Shanhun Jan 1991

Whole-Farm Planning : Success At Wilgi Creek, Kevin Shanhun

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

Ian and Bev Lynch own Wilgi Creek, a 376 ha mixed farming property at West Mount Barker in the 700 mm rainfall zone. In 1983, they started a whole-farm plan to overcome the problems of declining production caused by waterlogging (their biggest problem), salinity and deterioration of the remnant native vegetation. Today, their property is an example of a successful, wholefarm land conservation plan based on agroforestry, timber production, water harvesting and improved pastures.


The Greening Of Australia, Martine Scheltema Jan 1991

The Greening Of Australia, Martine Scheltema

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

Many urban Australians have little understanding of the problems of land degradation because it's an extremely slow process that doesn 't directly influence their day-to-day lives. Understandably, they would have trouble relating to sub-soil compaction, waterlogging, increased soil acidity and salinity. They also have trouble comprehending why fencing according to soil type is an important management tool for farmers, or what role contour banks, drainage systems, the addition of gypsum and planting trees have in reversing land degradation. But given that tree loss "has been at the core of almost every aspect of land degradation in Australia ", and that …


Tree Crops For Profit And Land Improvement, John Bartle Jan 1991

Tree Crops For Profit And Land Improvement, John Bartle

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

Western Australian agriculture is deficient in good perennial species. The traditional segregation of agriculture and forestry has diverted attention from commercial wood producing trees as a potential perennial crop. Recently, scientists have made rapid progress in developing tree cropping systems suitable for extensive use in the wetter (more than 600 mm average annual rainfall) areas of the lower south-west. There is potential for a major industry based on fast-growing eucalypts for pulpwood. The foundations for this industry developed from work on agroforestry, forestry sharefarming and salinity control.


Revegetating Salt-Affected Land With Shrubs, Ed Barrett-Lennard, Fionnuala Frost, Steve Vlahos, Norm Richards Jan 1991

Revegetating Salt-Affected Land With Shrubs, Ed Barrett-Lennard, Fionnuala Frost, Steve Vlahos, Norm Richards

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

The establishment of salt-tolerant shrubs such as saltbush and bluebush on salt-affected land reduces the risk of soil erosion, and can also fit into farm programmes as a profitable enterprise. Salt-tolerant shrubs can be used as forage for sheep in summer and autumn, when the availability of annual pastures is low or annual pastures are just beginning to emerge. This article describes three methods for establishing shrubs on salt-affected land and what affects shrub establishment.


Bulletin No 4176 - Agroforestry With Widely Spaced Pine Trees, Richard Moore, Peter Jenkins, Geoff Anderson, Phil Scott Jan 1991

Bulletin No 4176 - Agroforestry With Widely Spaced Pine Trees, Richard Moore, Peter Jenkins, Geoff Anderson, Phil Scott

Bulletins 4000 -

Combining a softwood timber crop with other forms of agriculture on the same land can make better use of available space, soil and water, and lead to higher productivity from farms.

This Bulletin outlines the potential benefits of, and a programme for, the growing of pine on farmland in Western Australia in conjunction with either pasture or another crop. The agroforestry system described has been well researched in Westem Australia.

The main objectives of agroforestry are to produce high quality timber while maintaining adequate pasture for either grazing or fodder cropping until the timber is harvested.

Vegetation Of Saratoga Landing Blackland Prairie, Thomas L. Foti Jan 1990

Vegetation Of Saratoga Landing Blackland Prairie, Thomas L. Foti

Journal of the Arkansas Academy of Science

Saratoga Landing Blackland Prairie is a 75-ha site owned by the U.S. Army Corps of Engineers and managed cooperatively with the Arkansas Natural Heritage Commission to protect its blackland prairie community and rare plant species. The site is a complex of prairies and forests, as interpreted from aerial photos and maps. It was substantially prairie at the time of settlement, and forest cover did not increase greatly until after 1951, apparently due to effective suppression of wildfires after that time. Plot sampling characterizes an individual prairie on the site as being dominated by a herbaceous canopy, but with a substantial …


Trees In The Peel-Harvey Catchment, C S. Peek, Richard Silberstein Jan 1989

Trees In The Peel-Harvey Catchment, C S. Peek, Richard Silberstein

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

The peel-Harvey catchment has been the focus for an intensive research and extension programme to reduce phosphorous run-off flowing into the Peel Inlet and Harvey Estuary, while maintaining agricultural productivity.

One of the proposed management strategies is to plant large areas of trees on the catchment's leaching sands. Farmers would be encouraged to take this option if growing trees was at least equal, in financial return, to the present agricultural land uses.

Preliminary data indicate that growing Eucalyptus globulas (Tasmanian bluegum) for woodchipping may be at least as profitable as agriculture. Tree plantations also have the added potential to reduce …

Wildlife Habitats In Managed Rangelands-- The Great Basin Of Southeastern Oregon, Wayne Bowers, Bill Hosford, Art Oakley, Carl Bond Jan 1974

Wildlife Habitats In Managed Rangelands-- The Great Basin Of Southeastern Oregon, Wayne Bowers, Bill Hosford, Art Oakley, Carl Bond

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

All land management activities on managed rangelands will have some impact(s) on fish habitat; those in the riparian zone will have the greatest impact(s). Native trout populations in the Great Basin of southeastern Oregon exhibit predictable responses to alterations in their habitats; optimum production of native trout is therefore achievable through careful habitat management.


Stem Canker Disease Of Red Flowering Gums, W P. Cass Smith Jan 1970

Stem Canker Disease Of Red Flowering Gums, W P. Cass Smith

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

Of the many native Eucalypts in Western Australia few are more attractive than the red flowering gum.

It flowers generally during the Christmas period and provides a beautiful display for several weeks, with blossoms of several colours including dark red, scarlet, orange and pink.


Behavior Of Pesticides In Plants, Logan A. Norris Jan 1969

Behavior Of Pesticides In Plants, Logan A. Norris

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

A number of chemicals of diverse characteristics have arbitrarily been classed together on the basis of their use and given the descriptive name "pesticides. " An unfortunate aura of mystery has developed about these chemicals. However, there is nothing unique or mysterious about the chemicals we refer to as "pesticides." Like other chemicals, they have properties which can be accurately measured; they obey all the laws of physics, chemistry, and biology.


South Dakota Bird Notes, Keith E. Evans, Roger R. Kerbs Jun 1967

South Dakota Bird Notes, Keith E. Evans, Roger R. Kerbs

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Approximately 90,000 small stock ponds are scattered throughout South Dakota. The majority of these ponds are less than 10 acres in size, and depend entirely on surface runoff for their water supply. Although their primary purpose is to provide drinking water for livestock, many species of waterfowl and shorebirds use the pond areas for resting and feeding during spring and fall migrations, and for nesting habitat throughout the summer.

Neither the amount of use nor the potential for use by birds on stock ponds in South Dakota is known. Preliminary data presented here are results of waterfowl observations on 13 …


Control Of Eucalypt Regrowth, J G. Paterson Jan 1967

Control Of Eucalypt Regrowth, J G. Paterson

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

EUCALYPT regrowth has presented a problem to farmers throughout the State for many years.

Some species are checked by heavy grazing although, in the main, this method is far from satisfactory.


Fodder Shrubs In The Murchison, D G. Wilcox Jan 1962

Fodder Shrubs In The Murchison, D G. Wilcox

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

THE Murchison pastoral country is usually thought of as either having a perennial grass cover, as in the Wandarrie, or as Mulga country with trees and short grass.

It is easy to overlook the small shrubs which occur all over the Murchison in every type of situation, and can provide high quality feed for sheep.
