Black wattle problem emerges in Indian forests. Its uncoordinated control could create a potential conflict of interest. It is still used for these today. Black Wattle, also known as Acacia mearnsii, refers to a type of tree and shrub indigenous to Australia. Due to the ability of A. mearnsii to form shady thickets and drop large quantities of litter, other plant species are frequently out-competed and floral diversity is consequently reduced where this tree becomes invasive (Weber, 2003).

Proceedings of an International Workshop held in Bangkok, Thailand, 11-15 February 1991. At 2 to 4.5 years after planting, Australian mainland provenances, especially those from New South Wales and Victoria, were superior to Tasmanian sources and the best of the Australian material was far better than the local landraces (Gao and Li, 1991; Gao et al., 1991).

Acacia mearnsii is known as the Black Wattle Tree. The tree is regarded as naturalized in Portugal (Le Floc'h, 1991). A. mearnsii is recorded as being highly competitive and eventually reducing the presence of native and/or indigenous vegetation, especially in South Africa (De Wit, 2001; ISSG, 2007). These results are largely in accordance with field data from South Africa where high altitude New South Wales provenances were significantly more frost-tolerant than low altitude New South Wales and Victoria provenances. Systematics and phytogeography of Australian species of Acacia: an overview. mearnsii has a hermaphroditic breeding system (Cronk and Fuller, 1995) and is regarded as an outcrossing species with partial self-compatibility. PROTA4U web database., [ed. It may occur on the fringes of closed-forest and rarely in woodland and coastal scrub. It is a host of the KwaZulu-Natal fruit fly which is an economic pest. Black wattle is part of Australia's iconic acacia family, but it's largely regarded as a pest overseas. ; many ref, Boucher C, 1980. ; 77 ref, Booth TH, 1992.

Across the whole of South Africa, the estimated annual consumption of water by A. mearnsii is estimated to be in the order of 300 million m³ (Anon., 2000). The Black Wattle species was introduced to South Africa for its timber in the 1800’s. A large proportion of the seed may become dormant in the soil and seed may remain viable for more than 50 years (Dean et al., 1986).Reproductive BiologyA. ], Lee SS, 1993.

This is a list of Acacia species (sensu lato) that are known to contain psychoactive alkaloids, or are suspected of containing such alkaloids due to being psychoactive.The presence and constitution of alkaloids in nature can be highly variable, due to environmental and genetic factors. There are several papers providing climatic profiles for the species combining information from both natural and planted occurrences; the most recent of these being Booth and Yan (1991), Booth (1992; 1997) and Yan et al.

In South Africa well-managed have produced the equivalent of 3 MT/ha tannin, about twice the average, when grown in rotations in excess of 12 years. ACIAR Proceedings No. Sickle-shaped, these are between 9 and 15 cm (3 1 ⁄ 2 and 6 in) long, and 1–3.5 cm (1 ⁄ 2 – 1 1 ⁄ 2 in) wide. Black wattle is also excellent wood for pizza ovens, potjies and fireplaces. Coastal localities have no heavy frosts, inland there are from 1-20 per annum and at some higher altitudes up to 80 are recorded, with a record low of -12°C. This prevents multi-stemmed trees from developing and which are more difficult and costlier to control. Sickle-shaped, these are between 9 and 15 cm (3 1 ⁄ 2 and 6 in) long, and 1–3.5 cm (1 ⁄ 2 – 1 1 ⁄ 2 in) wide. 35, 209-214; 3 ref, Gao CB, Li JY, Williams ER, 1991. High altitude New South Wales provenances (Bungendore, Bombala-Dalgety and Cooma) and two low elevation provenances, Apsley (Tasmania) and Minhamite (Victoria) were the most tolerant. It is also known to be invasive in California, USA, Burundi, Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, Zimbabwe, Jamaica, Brazil, New Zealand and Réunion, has shown a tendency to invade and cause concerns in other countries, e.g. Tabberabbera, Victoria, Australia. In Rwanda, self-established stands of A. mearnsii are common above 1600 m altitude, with the species mainly found in the Congo Nile Crest, Non-volcanic Highlands and Central Plateau agro-ecological zones (Seburanga, 2016).
