Principal historic growing areas include over 200,000 ha of plantations in Brazil (Higa and Resende, 1994) and 160,000 ha in South Africa (Boucher, 1980) down from 325,000 during peak tannin production in the 1960s (Wiersum, 1991).

As A. mearnsii is an important commercial plant as well as being extremely invasive, it is important that any control methods limit spread without affecting growth of cultivated trees. Seeds are also very long-lived, as is common with hard-coated legume seeds, and it may be assumed that seeds could remain viable for 50-100 years.Environmental RequirementsA. http://www.prota4u.info, Raymond CA, 1987.

A. mearnsii fixes atmospheric nitrogen and this allows it to survive on relatively infertile sites. Assessment and Management of Plant Invasions.

In Brazil, provenances from coastal New South Wales are performing best among a limited number of natural provenances under trial (Higa and Resende, 1994). In tropical countries, this species is attacked by various insects including herbivores (Acanthopsyche junode), stem-borers (Platypus solidus) and caterpillars (Achaea lienardi).

In more tropical areas, A. mearnsii is best grown in the highlands at 1500-2500 m with a mean annual rainfall of 900-1600 mm and mean annual temperature 12-18°C (Webb et al., 1980).

Flowering takes place from October to December in Australia (Searle, 1997), during September to October in Brazil (Stein and Tonietto, 1997) and from late August to early October in South Africa (Sherry, 1971). Patterns of morphological variation in seedlings of A. mearnsii were studied by Bleakley and Matheson (1992). (2010) used A.mearnsii as a case study for a risk assessment in Wenzhou, China.
