Natural populations

Eucalyptus blakelyi is a common tree species in the grassy woodlands of the western slopes on the tablelands of New South Wales and Victoria [1,2]. In Queensland it occurs in the Stanthorpe area. This species can attain up to 25 m in height and prefers alluvial flats, midslope terrain or depressions with seasonal water flows. It is often found on loamy soils but also tolerates heavier types that have poorer soil properties [1].

Flowering and seeds

Eucalyptus blakelyi flowers mainly during November to December [1,3,4]. Abundant flowering in this species occurs on a 2-3 year cycle, depending on seasonal conditions. Seed capsules persist on trees until at least the following summer. There are about 600 viable seeds per gram; seeds start to germinate in about 7 days if grown at 25°C with no pretreatment required [4].

Cultivation and uses

Eucalyptus blakelyi is frost and drought tolerant and can be grown on relatively heavy soils. It is an important species in the honey industry as it provides a valued source nectar and pollen for bees [3]. The wood is dense, very durable and is used for fencing and firewood [1]. On land cleared for agriculture, remnant trees of this species have value in providing shade and shelter for stock. The seasonal susceptibility to defoliation by insects, such as lerps and Christmas beetle larvae, has resulted in the decline of this species in some areas and this could affect its use as revegetation species.
