Five facts about river red gums 1.
The river red gum (Eucalyptus camaldulensis) is the most widely distributed eucalyptus species in Australia.
Most of Victoria’s red gum forests occur along the channels and floodplains of inland waterways, principally the Ovens, Goulburn and Murray rivers. The largest areas are Barmah Forest and Gunbower Island, both on the River Murray.
In a well-watered forest, river red gums can grow up to 45 metres tall with long, twisted trunks. In more open forest and woodland, the trees are often shorter, with thick twisted trunks and large branches.
River red gums need periods of partial flooding, where their trunks may be inundated for months. Seeds are washed to high ground during a flood and germinate to take root and grow before the next flood submerges the new tree.
A river red gum forest can produce 250 million seeds per hectare per year. Most seeds fall in spring and summer as the floods are receding. Ideal conditions for germination occur if the flood waters recede in spring, allowing sufficient time for seeds to germinate and grow prior to the hot, dry conditions of summer.
