The arboretum was incorporated on the 16th of May 1984. The site originally consisted of 47ha of farmland and remnant forest which was purchased with Australian Bicentennial Grant funding. The first plantings of woody plants to add to the existing trees was in 1986.
Since then, a botanical annexe at Hogg Creek has been added to the site, comprising 1.8ha purchased allowing access to an adjoining public reserve. Combined they are described as the Hogg Creek Botanical Annexe. The Annexe has a high degree of biophysical naturalness although the steep sides of the valley allow light in and thus weeds to establish themselves.
11ha adjoining the main Eugenana site was gifted in 1996 by the then North Forest Products to help protect the landscape values of the sites location. In 2009 a further 7.9ha, consisting of a disused quarry floor and some cleared land surrounding the Eugenana State Reserve has been purchased.
Total area of the main site is 66ha with some 40ha for the collection and 22 of local natural vegetation. The balance is either quarry floor or infrastructure.
The main site encompasses a section of the Don River where it adjoins Melrose Creek, surface limestone formations, old limestone quarries dating from circa 1860, associated tramway and railway formations and infrastructure associated with landscaping and managing a landscape arboretum.
There are over 4100 plants in the geographic and thematic collections, besides the indigenous species. Collections are mainly of temperate plants and include the Tasmanian, the Southern Hemisphere Conifers, leatherwood Eucryphia species and the cool temperate Nothofagus. Broadly, this represents a collection of the descendant of the flora of Gondwana.
65 species of birds have been recorded from the site including the Swift Parrot (Lathamus discolor) and the Grey Goshawk (Accipitifer novaehollandae).
The arboretum opens daily from 9am to sunset and requests a donation from visitors so it may continue its work.
Activities include walking the tracks in a peaceful setting to view the plants, the wildlife, the art, the landscape and the limestone heritage.
Platypus may be seen on Founders Lake during windless periods or late in the afternoon, Tasmanian Native-hens (Gallinula morterii) abound and other birds may be observed.
The picnic area contains shelters with coin operated barbecues and outdoor wood fired ones.
Exhibitions and other activities are listed on the website.
The organization, The Tasmanian Arboretum Inc., is an incorporated not for profit organization dedicated to operating a botanical institution for education, enjoyment of nature and research. It has a membership and is governed by an elected committee of up to 14.
Maintenance of the collections is largely by the volunteers. Development has been funded by a range of donors. The Devonport City Council currently grants $21,000 per annum to assist with operations of the cultural attraction.
