Acacia mangiun Advantages:

Provides timber and other wood products; can quickly suppress imperata grass (Imperata cylindrica) on degraded acid soils.

Some damage has been reported in young stands due to pinhole borers; some damage in nursery due to mildew and molds; wood has a high degree of ‘spring’ in milling test, a potential defect; heart rot can be a problem in older stands.

Fuelwood: 4800-4900 kcal/kg, produces high quality charcoal.
