Eucalyptus accedens (Powderbark Wandoo) Woodland

Sub-communities

Powderbark Wandoo over Scrub
See also Wandoo and Powderbark Wandoo 

See the report by Harvey and Keighery for sub-communities recognised by Keighery (Appendix 1), Gibson et al. (Appendix 2) and Griffin (Appendix 3). Many of these correspond to the sub-communities presented here, as is shown in the right hand columns of the tables in the appendices, but there are some unusual groups that are not recognised in this classification.

Species Identification

Tree, to 25m, forming a lignotuber. Bark smooth, pink-w hite, powdery. Flowers w hite, cream or yellow, from December to April.

Similar Species
Eucalyptus wandoo and E. accedens are outwardly very similar, but are distinguished by the seasonally orangey coloured powdery coating on the bark of E. accedens, its larger, more rounded buds and its distinctive rounded juvenile foliage. (For this and more information see EUCLID; Brooker & Kleinig; FloraBase; French.)

Soils and Landform

Lateritic gravelly soils, clay loam. Usually on lateritic breakaways or stony ridges, and usually above stands of E. wandoo.

Associated Species

Overstorey
Eucalyptus accedens may occur with E. wandoo as E. wandoo often occurs below E. accedens in the landscape, and occasionally with E. astringens, or with E. marginata on the western fringe.

Understorey
Shrubs include Hypocalymma angustifolia, Hibbertia hypericoides, Hakea lissocarpha, Acacia pulchella, Hovea chorizemifolia, Gastrolobium microcarpum, Lepidosperma leptostachyum, Bossiaea eriocarpa; these occur over sedges such as Gahnia australis, grasses such as Neurachne alopecuroidea and annuals such as Trachymene pilosa and Blennospora drummondii.

Benchmark Description

Recruitment
Juveniles with large blue green leaves are often present in a stand of healthy Eucalyptus accedens. The species forms a lignotuber. Regeneration strategies are not well know but are thought to be similar to E. wandoo and E. capillosa where continuous, although episodic, recruitment occurs from seed, resulting in muti aged stands.

Old Growth
Tree diameter has been observed up to 1.5m (P. White pers.comm.). Hollows readily form in dead branches or where limbs have fallen.

Organic Litter
Logs, fallen branches and bark common.
