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. …


Licuala Palms In Brunei Dusun Ethnobotany, Jay H. Bernstein, Roy F. Ellen Jan 1995

Licuala Palms In Brunei Dusun Ethnobotany, Jay H. Bernstein, Roy F. Ellen

Publications and Research

Several species of Licuala occur in the Merimbun area of Tutong district, Brunei Darussalam. One kind of Licuala, called benjiru by the local Dusun population, is often collected for sale as a vegetable. While Licuala is not generally considered an important economic plant, overharvesting in the Merimbun area suggests that conservation measures may be needed to protect it from local extinction. Besides benjiru, other kinds of Licuala recognized by the Dusun are called silad and ukang. The three kinds of Licuala do not have one overall name in the Dusun language, but constitute a covert category at the "intermediate" ethnobotanical …

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 …

Mathematical Programming Applications In Agroforestry Planning, Laurence H. Reeves May 1991

Mathematical Programming Applications In Agroforestry Planning, Laurence H. Reeves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agroforestry as a sustainable production system has been recognized as a land use system with the potential to slow encroachment of agriculture onto forested lands in developing countries. However, the acceptance of nontraditional agroforestry systems has been hampered in some areas due to the risk-averse nature of rural agriculturalists. By explicitly recognizing risk in agroforestry planning, a wider acceptance of agroforestry is possible. This thesis consists of a collection of three papers that explore the potential of modern stock portfolio theory to reduce financial risk in agroforestry planning.

The first paper presents a theoretical framework that incorporates modern stock portfolio …

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.
