Previous Factsheets

The Arboretum forests mostly consist of a single tree species, but Forest 20 differs in two ways: STEP is growing 16 species of eucalypt trees, selected to represent the major vegetation types of the region; and it includes shrubs, herbs and grasses to demonstrate the understorey plants commonly found in the region's forests and woodlands.

The STEP forest is an educational resource where visitors and school students can easily identify the trees and plants typical of the Southern Tablelands. Of particular significance are the trees and plants of the critically endangered 'Yellow Box/Red Gum Grassy Woodland' ecosystem. In this way, Forest 20 complements other Arboretum forests in telling an important conservation story about land use in south-eastern Australia.

Forest 20 is managed by the STEP community group in partnership with the National Arboretum Canberra and welcomes individuals, community groups, schools and others to join this exciting project. STEP have regular working bees and other activities.

The trees of Forest 20 were planted in 2009 and 2010. Understorey species are located close to the eucalypt species they commonly grow near in their natural habitat. The eucalypts and other plants have been placed in their relative landscape positions from low-lying grasslands to elevated dry and wet sclerophyll forests. This design enables visitors to learn about tree and understorey associations and further develop their understanding of the natural environments of the Southern Tablelands. There is also a small ephemeral wetland on the site where frogs have been recorded.

STEP features The Clearing, a comfortable and quiet outdoor education space for school groups and a place for visitors to rest or enjoy a picnic. The Clearing is a low impact and accessible space with a wide open outlook that integrates with the surrounding eucalypt trees.

Understorey and other plantings

Understorey species are sourced from local nurseries and from growers from the Australian Native Plants Society (Canberra Region). In 2012, STEP was invited to translocate three species from land in the Molonglo Valley that was scheduled for development. These were Chrysocephalum apiculatum (common everlasting), Eryngium ovinum (blue devil), and Cheilanthesaustrotenuifolia (rock fern). The translocation was successful and all three species can now be seen flourishing among the understorey plantings.
