The Tasmanian Arboretum, Botanical tree park in Eugenana, Tasmania, Australia.

The Tasmanian Arboretum covers 66 hectares at Eugenana, near Devonport, with about 40 hectares of geographic and thematic collections and 22 hectares of local natural vegetation. Its more than 4,900 plants are mainly temperate species, including Tasmanian woody flora, southern conifers such as Wollemia, Eucryphia and Nothofagus. The site takes in a stretch of the Don River where it meets Melrose Creek, surface limestone formations and old quarries.

The Arboretum was founded in 1984 and has focused on specialized tree collections and conservation areas since then. The facility documents Tasmania's natural heritage through systematic cultivation and preservation.

The name Eugenana, used for the site and the adjoining state reserve, comes from the local area. Old limestone quarries worked from about 1860 remain on the grounds, with tramway and railway formations left by the industry. Visitors can follow tracks past these workings, and Tasmanian native hens are common around the open ground.

The grounds are located roughly 12 kilometers from Devonport and open during daylight hours, with longer hours in summer than winter. The visitor center can help you plan walks and find your way around the paths.

The grounds hold the world's largest collection of Tasmanian woody plants and offer regular platypus sightings at Founders' Lake. This dual role as a research facility and wildlife viewing spot makes it special.
