Hancock Watch Site visit September 01: Plantation lies within Mullungdung Site of Botanical Significance in Central Gippsland. Pine plantation located just south of Lowe Road about 7km east of the village of Wonwron. The plantation is quite small is size and lies on flat land. Its eastern edge lies only 2.5 km west of Bruthen Creek. It was established in 1987, although 1962 experimental plantation plots lie to the north west and south of the plantation. This plantation has quite a large stand (for its size) of indigenous vegetation inside its boundaries. Quite a large portion of the northern edge is native vegetation including a large population of orchids. A very small area of Stringbark regrowth is found in the plantations’south east corner.
6. Mullungdung Forest: Regional significance
Area: ca. 280-300km2
Boundaries: Yarram-Traralgon Road between Gormandale and Greenmount (W), Merriman Creek between Gormandale and Stradbroke (N), South Gippsland Highway between Stradbroke and Greenmount (E and S). Includes catchments of Bruthen and Monkey Creeks.
Vegetation: Leptospermum myrsinoides Heathland, Damp Sclerophyll Forest, Sedge Swampland, Grassy Woodland, Coastal Heathland. Reasons for Designation: This site, which includes the Mullungdung State Forest and some surrounding areas of Crown and private land, is the largest area of native vegetation, below 300m, in the study area, and supports the largest stand of Leptospermum myrsinoides Heathland in the State. Kangaroo Swamp, in the centre of the site, is a large (ca. 1.5km2) Sedge Swampland surrounded by Coastal Heathland and is the largest ecosystem of this type in the study area.
A smaller, similar swamp in the north-west of the site (Willung Swamp) presents a good example of the juxtaposition of three communities (i.e. Leptospermum myrsinoides Healthland, Coastal Heathland and Sedge Swampland).
In the south-eastern parts of the site a floristically depauperate but predominately nativeversion of Grassy Woodland grows on a heavier soil than the sandy podzols supporting the above three communities. In the northern parts of the site, particularly around Monkey Creek, and on deeper more loamy soils, a Damp Sclerophyll Forest grows. Most of this vegetation has been burnt in the past six months so the floristic makeup of the understorey has not been adequately assessed. Significant species of the site include Eucalyptus consideniana (yertchuk), a species which is much more abundant in the study area than anywhere else in the State (the largest stand is in the Mullungdung site); Banksia serrata, predominantly a coastal species of East Gippsland and N.S.W. found growing with a grassy heath (see “Banksia Woodland” in Forbes et al. 1982), found in association with Leptospermum myrsinoides Heathland in the study area; Acacia howittii, endemic to the study area: Caladenia aurantiaca, restricted in Victoria to the study area and far East Gippsland; Calochilus imberbis, a rare species found only in a few isolated localities: the only other known locality in the study area is Cowra near Heyfield; Choretrum pauciflorum, a shrub which is widespread but never common; Gahnia clarkei, common in East Gippsland heaths but uncommon in more westerly districts; Gompholobium latifolium, common in Banksia Woodland in East Gippsland and coastal N.S.W. but very uncommon in the study area and probably at its western limit in this site; Helichrysum thyrsoideum, at its western limit in the study area; Pomaderris pilifera, endemic to Central and near East Gippsland; Grevillea chrysophaea; except for an isolated occurrence in the Brisbane Ranges this species is endemic to the study area south of the Princes Highway.”
