Scientific name: Eucalyptus hallii

Common name: Goodwood Gum

Other names: Clayton's Grey Gum

Conventionally accepted as Eucalyptus hallii (CHAH 2010).

The Goodwood Gum is a small to medium-sized tree growing up to 17 m in height. The species has smooth, mottled to dark grey bark on the trunk, which is shed continuously. New bark exposed after shedding can be orange or pink-grey in colour. The adult leaves are lance-shaped to sickle-shaped, 15 cm long by 2.5 cm wide and a glossy green or grey-green colour on both sides. The juvenile leaves are lance-shaped to ovate, measure 15 cm long by 8 cm wide and are arranged in pairs along the branches (Brooker & Kleinig 2004; Qld DERM 2010).

Up to seven white flowers are grouped into clusters. These clusters are found on laterally flattened stalks that reach up to 1 cm in length. The flower clusters arise from the junction between the leaf and the stem. Mature flower buds are egg-shaped, have a rounded or cone-shaped cap, measure up to 9 mm long by 4 mm wide and are without a stalk. The seed capsules are conical, with the pointed end joined to the stalk, have protruding valves and comprise of 3–4 chambers. The capsules are 5–8 mm long and 5–7 mm in diameter (Brooker & Kleinig 2004; Qld DERM 2010).

The Goodwood Gum is endemic to the coastal lowlands of Queensland. The species is found in scattered populations between Bundaberg and Maryborough (Qld DERM 2010).

In 1998, the species was thought to have an area of occurrence of approximately 1300 km² and an area of occupancy of 45 km² (Queensland CRA/RFA Steering Committee 1998).

A small number of populations are protected in Burrum Coast National Park (Woodgate, Kinkuna and Burrum River sections) (Qld DERM 2010a). The species is mostly found on freehold and vacant crown lands, with one population in State Forest 840 (Queensland CRA/RFA Steering Committee 1998; Queensland Herbarium 2008).

Goodwood Gum is found in open eucalypt forest or woodland in coastal areas on low, flat to undulating terrain with gentle slopes to broad rises (Chippendale 1988; Erskine 1992; Queensland CRA/RFA Steering Committee 1998). Soils preferred by the species are grey, sandy to silty in texture with an acidic reaction and derived from tertiary sedimentary rocks (Halford 1998). Also, a gleyed (waterlogged, often sticky and clay based) layer in the soil at a depth of between 35–60 cm is preferred. The altitudinal range of the species is between 7–70 m above sea level (Erskine 1992; Queensland CRA/RFA Steering Committee 1998). Much of this habitat has been cleared for agriculture and urban development.

The Goodwood Gum is often the dominant canopy tree, but does grow in association with a number of other tree species, notably White Mahogany (Eucalyptus latisinensis), Brown Bloodwood (Corymbia trachyphloia), Pink Bloodwood (Corymbia intermedia), Smooth-barked Apple (Angophora leiocarpa), Turpentine (Syncarpia glomulifera) and Broad-leaved Paperbark (Melaleuca quinquenervia) (Halford 1995l; Queensland CRA/RFA Steering Committee 1998; Queensland Herbarium 2008).

The Goodwood Gum flowers from December to February, however trees have been found with flower buds or fruits on them throughout the year (Queensland CRA/RFA Steering Committee 1998; Qld DERM 2010; Queensland Herbarium 2008). The species can sprout in the early stages of its life cycle from an underground lignotuber which is an underground swelling of the root crown containing buds and nutrients. It may also sprout from epicormic shoots which are dormant buds often found on old wood of trees. The species appears to become sexually reproductive when its girth exceeds 30 cm (Erskine 1992; Queensland CRA/RFA Steering Committee 1998). Juvenile trees can tolerate fire at 1–2 years of age (Erskine 1992; Queensland CRA/RFA Steering Committee 1998).

The species is garden cultivable and is tolerant of drought, poor drainage and infertile soils (SGAP Qld 2010).

The most common pollinators for Australian Myrtaceae, are insects. More specifically, anecdotal evidence (Erskine 1992) indicates native bees would be effective pollinators of the Goodwood Gum. Many tropical eucalypt species, like the Goodwood Gum, shed their seeds and drop their fruit after flowering. This is in contrast to southern species which may retain fruits for more than a year. No adaptation exists for secondary dispersal of eucalypt seeds by animals, with wind being the dispersal vector. Reasonable moisture and temperature conditions are all that is required for germination (Pryor & Johnson 1981; Queensland CRA/RFA Steering Committee 1998).

The Goodwood Gum may be confused with Bancroft's Red Gum (also known as Orange Gum) (E. bancroftii), which is another smooth bark species with a similar distribution. The Goodwood Gum can be distinguished from Bancroft's Red Gum by the former's ovoid buds with hemispherical or conical operculums ('lids' that cover the bud). In addition, the Goodwood Gum grows in comparatively drier and slightly more elevated sites than Bancroft's Red Gum (Queensland CRA/RFA Steering Committee 1998).

Habitat Loss

Sugarcane production, grazing by livestock, pine plantations, power line easements and housing development all threaten the habitat of the Goodwood Gum. Indeed, a large proportion of presently known populations of the species are estimated to be on land that may, in the future, be converted to agriculture (for example sugarcane), semi rural blocks or forestry. Conversion of the remaining populations' habitat to any of the aforementioned uses could be detrimental for the species, considering its naturally restricted distribution (Queensland CRA/RFA Steering Committee 1998).

Soil Hydrology

Changes in soil hydrology, through irrigation or water drainage, may affect the ability of this species to colonise new areas or persist in known populations. This is likely due to a connection between the species' distribution and the level of soil waterlogging in the area (Erskine 1992; Queensland CRA/RFA Steering Committee 1998).

Some populations occur in areas of remnant vegetation (Qld EPA 2008a), as defined under the Queensland Vegetation Management Act 1999, and therefore have legislative protection from broad-scale clearing (Halford 1998).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
