Weed characteristics form dense stands, aggressively invading to shade out native
plants. Miconias also have the potential to degrade crop, plantation and pasture
areas. It is a shallow-rooted tree which creates hillside instability making it an
erosion threat. It is the target of a national eradication program.
Dispersal is by birds, vehicles, machinery, footwear and animals. Mature plants can
produce up to 3 million seeds several times per year, creating a massive soil seed
bank. Seeds can persist in the soil for more than 8 years.
This species is a Class 1 declared plant under Queensland legislation.
