Pianggu is one of the native trees NParks identifies as an addition to Punggol Heritage Trail. Its scientific name is Horsfieldia irya.
It is a useful species for thinking about how planted landscapes can support wildlife. NParks’ species record describes fruit eaten by animals including hornbills and monkeys.
That ecological connection does not promise a fruiting tree or an animal sighting on your walk. Start with the interpretation, observe what is visible and let the rest remain a question.

The NParks Pianggu record lists Horsfieldia irya and several common-name variants.
The record describes alternate, stalked leaves that are often curved towards the tip. Compare multiple features and any available sign rather than choosing a name from leaf shape alone.
Do not scrape bark or break foliage to test a description. A reference can teach you about a species without requiring a hands-on identification.
NParks describes yellowish-orange fruit and orange-red to red coverings around the seeds, and records monkeys and hornbills as fruit consumers.
Learning that relationship is different from witnessing it. A tree without visible fruit can still belong to the species, and an animal may not be present during a short visit.
Ask a child what observations would support a feeding claim. ‘We read that this happens’ and ‘we saw it happen’ are both useful statements when kept distinct.
The official trail page names Pianggu among introduced native tree plantings. Here, adding a tree to the trail does not mean the species is non-native to Singapore.
The species record identifies Pianggu as critically endangered locally. A planted individual does not, on its own, demonstrate recovery of the wider wild population.
These distinctions help make a local walk more meaningful: planting, origin and conservation status describe different parts of the story.
Make a short entry with the name, source and features visible from your viewpoint. Mark reference-based details separately from your own observation.
Leave fruit and plant material in place, and do not feed wildlife to create a photograph or demonstrate a food relationship.
Our Punggol Heritage Trail guide introduces the wider outing. Check current access information and choose a route that leaves enough time for your return.
