About

Eucalyptus aggregata, commonly known as black gum, is a medium-sized tree that is endemic to southeastern Australia. It has rough, flaky bark, sometimes smooth on the branches, lance-shaped leaves, green to yellow flower buds in group of seven, white flowers and more or less cup-shaped fruit. It is a component of grassy woodland, often in low-lying or swampy areas, much of which has been cleared and it is under threat.

Where it grows

Black gum is a rare species found from Capertee and Bathurst in central New South Wales, south through central and southern tablelands, with an isolated population near Woodend in Victoria. It has a very patchy and scattered distribution, as much of the land throughout its range has been cleared for agriculture. Eucalyptus aggregata grows in woodland and is associated with candlebark (Eucalyptus rubida), ribbon gum (E. viminalis), black sally (E. stellulata) broad-leaved peppermint (E. dives) and snow gum (E. pauciflora), with a grassy understory of river tussock (Poa labillardieri) and silver top wallaby grass (Joycea pallida). The soil is generally poorly drained, alluvial or swampy, with the black gum growing in low-lying areas. These are also natural frost hollows, where cold air persists in the cooler months. It is found at altitudes above 700 metres (2,300 ft), where there are heavy frosts and snow in winter.

Uses

Although its soft timber is of little use, the species is versatile in that it grows in other areas where few other local species thrive, and can be a useful shade tree with its dense canopy. Its foliage can be used as fodder.
