SCHEDULE
Weeping Myall – Coobah – Scrub Wilga Shrubland of the Hunter Valley
The Weeping Myall – Coobah – Scrub Wilga Shrubland of the Hunter Valley ecological community of woodland of Weeping Myall (Acacia pendula) up to 10 m high with Coobah (Acacia salicina) and Scrub Wilga (Geijera salicifolia). Yarran (Acacia omalophylla) and Stiff Canthium (Canthium buxifolium) are also present in the small tree/shrub layer. The ground stratum is dense and primarily grassy. Grasses include Kangaroo Grass (Themeda triandra/australis), Wallaby Grass (Austrodanthonia spp.), Snow Grass (Poa sieberiana) and Barbed Wire Grass (Cymbopogon refractus) (Benson in prep.). Some exotic grasses have also invaded the site.
The ecological community occurs in a small stand on heavy, brown clay soil at Jerry's Plains in the Hunter Valley, in the South Hunter Province of the Sydney Basin Bioregion (Benson in prep.).
There is one patch of two hectares of the Weeping Myall - Coobah - Scrub Wilga Shrubland of the Hunter Valley ecological community remaining. The patch contains about 200 Weeping Myall trees. The patch occurs at Jerry's Plains, including the cemetery (Benson in prep.). None of this ecological community exists in protected areas (Benson in prep.).
The Weeping Myall that dominates this ecological community is disjunct from the major occurrences on the Liverpool Plains, 100 km to the east. It is probably a relic from the last ice age when the Hunter Valley would have been dominated by "western semi-arid" flora (Benson in prep., T. Tame pers. comm.).
Characteristic native plant species of the Weeping Myall - Coobah - Scrub Wilga Shrubland of the Hunter Valley ecological community. Not every species may be present at all times. This list is not comprehensive, and does not include all plant species found in the ecological community.
