"Himalayan ash (Fraxinus griffithii) is commonly cultivated as a street and garden tree, particularly in the warmer parts of eastern Australia. It has only been common in cultivation in recent times, and has become popular as a street tree because of its low-growing habit (i.e. it does not interfere with power lines)., This species is beginning to spread from cultivation and is showing invasive tendencies in the coastal districts of eastern Australia. Large numbers of seedlings are often seen growing under adult trees, and its windblown seeds are germinating in nearby natural habitats. For example, it has become naturalised at Maleny on the Sunshine Coast in south-eastern Queensland, where it is spreading from plantings into nearby rainforest areas., Himalayan ash (Fraxinus griffithii) is also invading shaded habitats in riparian areas along the Enoggera Creek catchment in northern Brisbane. In addition to this, there are unconfirmed reports that it is naturalised in other parts of south-eastern Queensland (e.g. on the Gold Coast, in Toowoomba and in other parts of Brisbane). Himalayan ash (Fraxinus griffithii) is also listed as an ""alert weed "" in the Sydney North region in central New South Wales."
