Manna Gums – tree-hollow heaven

Manna Gums (Eucalyptus viminalis) are a major component of Strathbogie Forests in higher rainfall areas. They don’t grow to the size of trees in Tassy, the Otways or the Central Highlands, but they do get big and old enough to develop many hollows over a life-time. Manna Gums regularly drop limbs as they grow and each broken branch-stub is the site of a future den or nest hollow.

Here’s a quick pictorial profile of a ~35 m Manna Gum, with a 1.24 m DBH. The tree has dozens of hollows, is likely 100+ yo and sheds masses of bark and leaf litter annually.

It’s one of the bigger trees in the forest and is likely a critical Greater Glider habitat tree. And I’m sure it’s hollows are also home to hosts of insects, spiders, beetles, bats, birds and other mammals. For the cost a few limbs along the way, this tree is now a biodiversity hot-spot and dominates the immediate nutrient economy. And just look at how that ribbony bark hangs and curls to provide the perfect habitat for insectivore’s diet – the tree attracting yet more biodiversity to itself. Though it’s one of the bigger trees in the forest, it’s still actively growing and will hopefully be with us for a while yet.
