Ecology The gardens include a mixture of native and non-native vegetation which invariably hosts a diverse range of both native and non-native fauna. The gardens host over 10,000 floral species, the majority being non-native species. The gardens were the origin from which many introduced species spread throughout south-eastern Australia as seeds were traded between early European botanists in the mid-19th century, studying the Australian flora. Native vegetation From the establishment of the gardens in 1846, much of the native vegetation was removed as botanists such as Baron Von Mueller planted a range of species from around the world. While initially much of the native wetlands and swamplands in the gardens were left, around the turn of the 20th century these were re-landscaped to create the Ornamental Lake. Despite this, however, there are some large eucalypts remaining including the prominent Separation Tree, a 300-year-old River Red Gum, under which Victoria was declared a separate colony. In August 2010 the Separation Tree was attacked by vandals and then attacked again in 2013, by 2015 it was dead and removal of the canopy and branches commenced. The Royal Botanic Gardens, Cranbourne focus solely on Australian native plants. Non-native traditional gardens The Royal Botanic Gardens Melbourne were initially intended to be a horticultural exhibition for the public to enjoy, many seeds were traded between early European botanists such as Arthur and Von Mueller, who planted non-native species. The Queen and her grandfather, Dame Nellie Melba and Paderewski contributed plantings on occasions throughout the history of the gardens. Plant science Since its earliest days, the Royal Botanic Gardens is involved in plant research and identification. This is done primarily through the National Herbarium of Victoria, which is based at the Gardens. The Herbarium is also home to the State Botanical Collection, which includes over 1.5 million dried plant specimens, and an extensive collection of books, journals and artworks. Research findings are published in the journal Muelleria, which is a scientific representation of the work done in the Gardens in any one year. More recently, the Australian Research Centre for Urban Ecology has been established to look at plants that grow in urban environments specifically.
