Acacia-dominated scrubs and tall open shrubland, often developing dense, nearly monotypic populations along dry, stony or sandy drainage lines in disturbed sites such as road verges, gravel pits and burnt areas, growing in a variety of soil types[286]. It occurs in Australia in red sands. It is a tropical plant.  The seed of many Acacia species, including this one, is edible and highly nutritious, and can be eaten safely as a fairly major part of the diet. Not all species are edible, however, and some can contain moderate levels of toxins[1295]. Especially when harvesting from the wild, especial care should be taken to ensure correct identification of any plants harvested for food[K]. Especially in times of drought, many Acacia species can concentrate high levels of the toxin Hydrogen cyanide in their foliage, making them dangerous for herbivores to eat.
