The Silver Gum is a small tree growing to 8 m high, usually with a widely spreading crown. It retains 'juvenile' foliage (that is, opposite and highly waxy) to maturity. It readily hybridises with Eucalyptus ovata with which it grows at both known sites (Jelinek 1991).
The Silver Gum is endemic to south-central Victoria. Two natural populations are known (although the species is widely grown as an ornamental tree). There are also a lot of naturalised and planted populations around Victoria (J.G.Eichler, J.A.Jeanes, D.G.Cook, G.W.Carr & K.Rule, Victorian Workshop 2000, pers. comm.) e.g. at Noogee (G.W.Carr 2000, pers. comm.).
The larger population, covering approximately 4 ha, is 2 km south of Buxton in the 16.9 ha Buxton Silver Gum Reserve, consisting of about 100 plants (J.G.Eichler, J.A.Jeanes, D.G.Cook, G.W.Carr & K.Rule, Victorian Workshop 2000, pers. comm.), occurring on 2 parcels of freehold land adjacent to the reserve (one of these occurs on the opposite side of the Maroondah Hwy). This population is near the Acheron River, a tributary of the Goulburn River, and ultimately the Murray River.
The second population consists of approximately 15-20 trees (J.G.Eichler, J.A.Jeanes, D.G.Cook, G.W.Carr & K.Rule, Victorian Workshop 2000, pers. comm.) scattered over 4 ha on the Yarra River flats at Yering. Two hectares of these are within the Spadonis Reserve (managed by NRE); the other 2 ha are on adjacent private grazing land.
In 1991 it was estimated that fewer than 500 plants grew in the wild (Jelinek 1991). However, in 2000 it was suggested that the Buxton site comprised approximately 600 adult trees (Adams & Simmons 2000).
Any of the gullies that come out of the western side of the Black Range could be suitable habitat (J.G.Eichler, J.A.Jeanes, D.G.Cook & K.Rule, Victorian Workshop 2000, pers. comm.).
There are some doubts about the population at Yering (20 or so plants). The morphology is different to typical E. crenulata. Diane Symons has published on the genetics, but it needs further research (J.G.Eichler, J.A.Jeanes, D.G.Cook & K.Rule, Victorian Workshop 2000, pers. comm.).
The Silver Gum occurs on flat and very gently sloping areas near watercourses, often swampy, usually more or less in pure stands in woodland (Chippendale 1988).
Both known sites occur in low-lying sites prone to inundation (although the channelisation of Olinda Ck at Yering has undoubtedly reduced the frequency of flooding at that site) (N.Walsh 2001, pers. comm.).
At the Buxton site, the low tree stratum includes Eucalyptus ovata and Acacia melanoxylon. Prominent shrub species are Coprosma quadrifida, and Leptospermum lanigerum. The ground layer includes Blechnum minus, Gahnia sieberiana, Hydrocotyle hirta, Hypericum japonicum, Lomandra longifolia, Poa tenera, Pteridium esculentum and Viola hederacea. Cassytha melantha is abundant as an aerial stem parasite (NRE 2000; N.Walsh 2001, pers. comm.)..
At Yering, the vegetation has been modified to a larger extent through past practices, but other trees there include Eucalyptus ovata, E. viminalis and Acacia dealbata. Shrubs include Hymenanthera dentata, Melaleuca ericifolia and Pomaderris vaccinifolia and the native ground layer is comprised mainly of Poa labillardierei and Carex appressa (NRE 2000; N.Walsh 2001, pers. comm.).
The Silver Gum flowers mainly in spring. Dense ground cover at both sites may be inhibiting recruitment (Jelinek 1991).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
