A family tree hunt for your neighbourhood streets

Identifying street trees becomes a slow, rewarding family outing, even on a familiar route to the school gate, bus stop or local shops. Instead of searching for something rare, invite each family member to notice differences: one tree may have smooth, peeling bark, another deeply furrowed bark, while their leaves might be round, narrow or divided into leaflets. A notebook, pencil and camera are enough to begin.

Look before you touch, and let curiosity stay away from mouths. Stay on the footpath, do not pull branches or climb, and collect fallen leaves rather than stripping anything from the tree. Choose a comfortable time of day, carry water during hot weather, and wash hands after handling unfamiliar plant material. Sap, pollen and some fruits can irritate, and no sample is worth making a child unwell.

Start with the shape of the tree

Begin with the whole silhouette rather than a single leaf. Is the canopy upright, spreading, round or narrow? Are branches dense or open, and do they spread low towards the footpath? Note whether the tree keeps its leaves through winter. These features narrow the field quickly, although street pruning can make two species look surprisingly similar.

Next, check the setting without assuming that every tree belongs to the same group. A large evergreen on a nature strip may be a eucalyptus, while a deciduous London plane or elm is also common in many Australian cities. A tree with purple flowers in spring may be a jacaranda, but its leaves divide into many small leaflets, not the broad blades of a plane.

Record an approximate height using familiar references, such as a single-storey house, a basketball hoop or an adult beside the trunk. A straight trunk with a high, branching crown suggests a different growth habit from a shorter, multi-branched tree. Treat these as clues, not a final identification.

Read leaves without picking them

Leaves carry the most useful information, especially when you examine a fallen sample. Check that it has not blown in from another tree, then look at the blade and stalk: is the leaf simple, with one undivided surface, or compound, with several leaflets attached to one stalk? Examine whether the edge is smooth, toothed or lobed. Turn it over and note the colour, thickness, hairiness and pattern of veins.

Try matching those observations with familiar examples. A London plane has broad, shallowly lobed leaves; a crepe myrtle has smaller oval leaves; a jacaranda has finely divided compound leaves; and mature eucalypt leaves are usually long, narrow and hang vertically. Holly oaks keep glossy, prickly-edged leaves through winter. These descriptions offer options, but leaf arrangement along the twig and the buds can settle close matches.

For younger children, measure a leaf with a ruler or trace around it on paper. For older children, note whether leaves alternate along the twig or sit opposite one another, then compare two trees side by side. Do not twist or strip a leaf still attached to the tree to test it; a naturally fallen sample provides the same lesson without harming the canopy.

Match bark, buds and flowers

Bark is a reliable clue when leaves are unavailable. London planes often show pale plates that flake away to reveal patches of cream, green or grey. Jacarandas generally have dark, furrowed bark, while young crepe myrtles can have smooth, mottled trunks. Eucalypts vary enormously, from smooth, ribbon-like bark to rough, fibrous or persistent woody layers, so describe the pattern rather than rely on a group label.

Flowers and fruit add a seasonal layer. Crepe myrtles carry crinkled flower clusters in summer, bottlebrushes show dense cylindrical flower spikes, and jacarandas often produce purple panicles before their brown pods develop. The familiar fuzzy balls hanging from London planes are seed clusters, not fruits in the everyday sense. Note their shape and colour instead of squeezing or opening them.

Check buds and leaf scars when twigs are within reach from the ground. Pointed buds, sticky leaves and paired buds can distinguish one tree from another, while fresh fruit may narrow an identification further. Photograph buds with a coin or pencil for scale, but leave every attached twig undisturbed and never handle unknown sap.

Recognise familiar trees in Australian cities

Australian cities offer useful contrasts. Melbourne is well known for its mature London plane avenues, while Sydney streets often feature jacarandas that colour the spring walk in purple. Brisbane gardens can include subtropical paperbarks and bottlebrushes, and Perth's dry summers favour a different mix of drought-tolerant evergreens. Across southern cities, deciduous elms and planes make winter leaf fall especially noticeable.

These examples are starting points, not fixed rules. Climate, council planting policies and the age of a street affect what grows there, and the same species can look different in a wet coastal suburb, a hot western suburb or a sheltered inland town. A native tree may have been planted outside its natural range, while an introduced tree can still provide useful shade and habitat.

At a community plant swap or a tree seedling stall at a local market, look for the botanical name and place of origin on the label. Sellers can often explain which trees suit local conditions, while the labels provide the precise wording needed for your own records. Never collect a seed or cutting without the grower's permission.

Check names against reliable references

Use a reference designed for Australian plants rather than guessing from a general tree guide. PlantNET supports identification in New South Wales, VicFlora covers Victoria, and FloraBase is useful for Western Australia; the Atlas of Living Australia records observations from around the country. iNaturalist can suggest matches from photographs, but its identification is not always a confirmed species.

Compare the suggested name with more than one feature. A common name may cover several related species, and a photograph of leaves alone can miss a decisive bud, flower or bark character. Read the plant description and look at photographs of the mature tree, not only a close-up. If two sources disagree, keep the name tentative and write down what still needs checking.

Photograph the whole tree first, then move closer to the trunk, bark, leaves and any buds or flowers. Include a scale object and take one image with the leaf turned over. Record the date, street and weather. Avoid posting an exact house number, particularly in a publicly shared identification record, because a street tree does not need that level of private detail.

Build a family tree record

Give each person a simple job. One child can photograph the canopy, another can trace a fallen leaf, and an adult can write the observations. Ask them to compare, rather than identify: does the leaf feel like leather or paper, is the bark cool or rough, and which tree has a rounder crown? These sensory descriptions make the activity meaningful for children who cannot read a botanical key yet.

A family tree record can contain the street, date, overall description, leaf details, bark, a photograph reference and a possible name with its scientific name. A clear note such as “possible London plane, check hanging seed clusters and mottled bark” is more useful than a confident guess. Mark uncertainty honestly; good tree records can be revised when a flower or fruit appears.

Look for local knowledge as well. Your council's urban-forest pages may list planting targets or street-tree species, and some councils maintain maps of individual trees. Nature-strip trees are often managed by the council, whereas front-yard trees usually belong to the household. A question to the council or a qualified local nursery can confirm a species without anyone needing to disturb the tree.

Make one verified tree record

Before leaving, choose one tree and make a brief, evidence-based observation. Write its location, leaf arrangement, bark pattern and any flowers, buds or fruit, then compare those details with a reliable field guide and the council's information. Record the result as probable or confirmed, keeping photographs together with the notes. This small archive can anchor future walks and show how the same street changes through the year.

The next step is a simple field kit: a notebook, ruler and sharpened pencil beside the front door before the family's next walk.
