Every tree we climb, prune or assess starts with the same question: what species is this? It sounds basic, but getting it wrong can lead to poor pruning decisions, unnecessary removals, or a nasty surprise when a branch behaves nothing like you expected. Different species respond differently to pruning, carry different risks of disease, suit different environments, and behave in their own way under load. With thousands of native and introduced tree species found across Australia, no arborist can rely on memory alone – instead, we use a methodical process of observation to identify a tree with confidence.
Start with the Big Picture: Distribution and Habitat
Before even touching the tree, its location offers clues. Certain species are strongly associated with particular soil types, rainfall patterns, altitudes and regional forest types. A towering eucalypt in a cool, high-rainfall mountain gully is a very different proposition to a similar-looking tree on a dry, exposed ridge. That said, plenty of trees are planted well outside their natural range, so habitat is a useful starting clue rather than a final answer.
Reading the Bark
Bark is often the fastest way to narrow down a species, especially from a distance. We look closely at several features:
- Hardness – is it soft and pliable, or hard and rigid?
- Texture – smooth, fibrous, flaky or deeply furrowed?
- Persistence – does rough bark extend right up into the canopy, or does it give way to smoother bark higher up?
- Colour and any distinctive patterns or ribbons of shed bark
- Smell – a surprising number of species have a recognisable scent when the bark is scratched
Form, Structure and Branching
Standing back and observing the tree's overall shape – whether it's rounded, spreading, columnar, weeping or pyramidal – gives another layer of information, provided we're looking at a naturally grown specimen rather than one that's been heavily pruned or shaped by wind and competition. We also study how the branches are arranged: the angle at which they leave the trunk, how many new shoots form each year, and the overall density of the canopy. Subtle differences here are what separate an upright, narrow crown from a broad, weeping one.
The Details: Buds, Leaves, Flowers and Fruit
Once the broad picture is clear, we move in for the finer details. Buds can be terminal, positioned where a leaf meets the stem, or arise unpredictably from roots or older wood. Leaves are assessed for arrangement along the stem (opposite, alternate or whorled), overall shape, the pattern of the leaf margin, and the venation running through the blade. If the tree is flowering or fruiting at the time of inspection, that's a bonus – flower colour, size and arrangement, along with fruit type, are often the clincher for a positive identification.
Botanical Names vs Common Names
A tree might be called "mountain ash" in Australia, the United Kingdom or the United States – and refer to three completely different species. This is exactly why arborists record and communicate using the two-part Latin botanical name, made up of the genus and the specific epithet. It's precise, internationally recognised, and leaves no room for the kind of confusion that common names can cause.
Careful, methodical tree identification isn't just an academic exercise – it's the foundation for every safe and effective decision an arborist makes afterwards, from how a tree is climbed to how it's pruned or treated.
