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. Yates et al.  list E. longicornis and E salmonophloia, E salmonophloia and E. longicornis, and E loxophleba and E. longicornis

Species Identification

Usually a well formed tree (rarely a mallee), to 30m high, forming a lignotuber. Bark grey/brown, rough, fibrous and fissured. Flowers w hite, from December to February. (For this and more information see EUCLID; Brooker & Kleinig; FloraBase; and French.)

Similar Species
Eucalyptus longicornis differs from the unrelated E. melanoxylon (Black Morrel) by having a long slender horn shaped operculum, truncated globose fruit with exerted valve tips and no pith glands on the branchlets.

Outlying Populations
Outliers of E. longicornis occur near Sandstone, near Leonora and north-east of Esperance (McQuoid; FloraBase).

Soils and Landform

Loam, often over limestone or clay loam on flats. Rich mineralised and often slightly saline dark red loams associated with the decomposition of the fine-grained dolerite gneiss dykes and outcropping units of the Yilgarn Block (McQuoid).

Associated Species

Overstorey
Often Eucalyptus longicornis occurs as a pure stand but it may occur with E. salmonophloia and E. melanoxylon, and occasionally with E. wandoo, E. loxophleba, E. astringens and E. kondininensis.

Understorey
Common understorey species include Sclerolaena diacantha, Lycium australe, Maireana trichoptera, Melaleuca merrallii, M. pauperiflora and Rhagodia drummondii.

Number of Sites and Polygons

46 sites and 12 polygons

Average Species Richness

17.3 spp. per 100m(35 sites)

Benchmark Description

Recruitment
Recruitment is not well understood, although Eucalyptus longicornis is known to resprout with conspicuous blue/green juvenile leaves. It has been observed at Lake Cronin (east of Hyden) to regenerate strongly from seed after fire. Regeneration appears over large areas rather than in ash bed patches, unlike E. salmonophloia (McQuoid).

Old Growth
Trunk diameter is recorded by Chippendale of up to 1m.

Fire
E. longicornis trees are killed by very hot fire but may resprout fom lignotubers and produce epicormic shoots after mild fire.

Comments

Red Morrel Woodland of the Wheatbelt is classified as a Priority 1 Ecological Community (see list on WA threatened ecological communities web page): Tall open woodlands of Eucalyptus longicornis (red morrell)  found in the Wheatbelt on lateritic, ironstone or granitic soil types. Sometimes found with E. salmonophloia (Salmon Gum), or E. loxophleba (York Gum) woodlands and has very little understorey. It is also found directly above lake systems in the central and eastern Wheatbelt. The landscape unit in which it is found is valley floors, usually adjacent to saline areas.
