Casuarina oligodon is useful on coffee plantations because it shades the coffee bushes and improves the soil by fixing nitrogen.

6. Best-Known Species 1984

Non-Australian species, such as Casuarina oligodon and Casuarina junghuhniana, grow in regions that are largely frost free.

4. Management 1984

Main Attributes The Papua New Guinea government is encouraging local people to grow Casuarina oligodon as firewood in the Highlands.

2. Experiences with Casuarinas 1984

The species is useful because it can grow on poorer soils than Casuarina oligodon and tolerates a wide range of rainfall and temperatures in the country.

8. Recommendations and Research Needs 1984

In the early 1960s, as a small-scale research project, Casuarina oligodon was successfully underplanted beneath Araucaria hunsteinii and Araucaria cunninghamii.

2. Experiences with Casuarinas 1984

In the Highlands of Papua New Guinea Casuarina oligodon is also planted in areas infested with Imperata.
