Welcome to The Leucaena Network

The Leucaena Network is a leading producer group in the grass-fed beef industry of Queensland.

Members include livestock producers, leucaena & pasture seed growers, researchers & extension personnel.

Leucaena is a high quality, long-lived leguminous forage tree.

Leucaena has been in Australia for over 100 years, varieties used for grazing were first introduced by the CSIRO in the 1950s for beef systems in tropical Australia.

Today more than 200,000 hectares of leucaena have been successfully established,  predominately in central QLD.

More recent plantings are found from Cooktown in north Queensland to Goondiwindi in the south.

The development of new cultivars has the potential to open up other areas in Australia to leucaena plantings.

Wonder Weeds: Leucaena could help reduce

cattle methane emissions

ABC Landline


Leucaena has been seen as a wonder fodder adding as much as a kilogram a day to cattle. But new evidence suggests that it doesn’t just help beef up livestock, it's also helping the planet by reducing the amount of methane cattle produce.

Top 10 tips to growing leucaena

Tip one

Comply with the Code of Practice

The Leucaena Best Management Code of Practice provides guidelines to minimize the risk of leucaena spreading outside of where it is planted while maximizing beef production potential.

Tip two

Carefully Select Your Variety

Existing varieties are Wondergraze, Tarramba and Cunningham.   The recent release of a new pyslid resitant variety, Redlands, will provide a variety suitable to coastal environments were psyllids are highly prevelant.

Tip three

Know Your Soil - Soil Testing.

Leucaena will grow in a wide range of soils but is most productive in fertile, deep and well-drained soils. It’s imperative to soil test paddocks selected for leucaena production prior to sowing to ensure adequate soil nutrient supply.

Tip four

Location, Location, Location

Situate your leucaena on deep soils in frost free areas, avoiding cold hollows or flats that regularly frost.

Tip five

Ensure Your Climate is Suitable

Although established leucaena can tolerate extended dry spells and droughts, the plant performs best in tropical climates with hot wet summers and mild winters with an average rainfall above 600mm.


Tip six

Establishment technique is critical

The right planting time and adequate soil moisture are critical for reliable leucaena establishment. Plant as early as possible between September and March (depending on winter temperatures and frost potential), but only when there is at least 60-90cm of sub-soil moisture.

Tip seven


Seed must be inoculated with a Rhizobium bacteria immediately before planting to enable efficient nitrogen fixation.


Tip eight

Observe Row Spacing

Suggested row spacings are between 6 and 12m depending on soil type, rainfall (or irrigation), and the grass: leucaena forage balance required. Planting twin rows (as opposed to single) can ensure a hedge if one row doesn’t come up.


Tip nine

The Right Companion Grass

Companion grass is required for sustainable leucaena plantings and for maximum grazing benefit.  A productive companion grass provides a balanced diet for cattle to maximize weight gain, utilizes the excess nitrogen produced by the leucaena, & provides ground cover to minimise stray leucaena seedlings & other weeds reducing runoff and erosion.

Tip ten

Do not rush preparation

Successfully establishing leucaena takes significant time and effort. Re-sowing a paddock because preparation was rushed is very costly. Do it properly the first time and leucaena will repay handsomely year in, year out for more than 30 years.
