Ipswich’s Most Common Trees at a Glance

  • What’s inside: Ipswich’s 18 most common trees—how many, how tall, where they grow, and how to recognise them. (Ipswich has ~690,000 trees total.)
  • Big three: Ironbarks, spotted gums, and blue gums dominate, making up nearly 90% of all trees. Popular urban picks (jacaranda, tuckeroo, palms, poinciana, citrus) are common but far far fewer overall.
  • How we counted: Estimated from Queensland bush maps, typical densities, and street/yard patterns. Closely related trees are grouped by familiar local names.

🔢 By The Numbers

  • ~690,000 – estimated total trees across the City of Ipswich
  • 18 – species/groups ranked in this report
  • 88% – share of all trees from ironbarks, spotted gum and blue gum combined
  • 320,000 – mid estimate of ironbark trees citywide
  • 210,000 – mid estimate of spotted gum trees
  • 70,000 – mid estimate of blue gum trees
  • 15,000 – river oaks fringing Ipswich’s creeks and rivers
  • 11,000 – weeping bottlebrush in streetscapes and along creeklines
  • 70.9 m – tallest audited “spotted gum complex” tree (NSW), showing species potential
  • ~5 – average trees per footy field of land across the LGA

Did you know?

The City of Ipswich has ~690,000 trees.

That’s about 5 trees for every footy field’s worth of land across Ipswich.

47% are one group: ironbarks.

88% are just three species.

Wild, right?

How we worked it out: not by walking every street. We used Queensland ecosystem maps to size bushland, applied realistic stems-per-hectare bands, then layered in streets, parks and yards using road length and common planting patterns.

Names and grouping: where locals use one name for close relatives, we grouped them (Ironbarks, Lilly pillies, Urban palms, Backyard citrus). Yard staples like citrus are included even if some sit under 3 m.

Methodology (what we actually did)

Step 1 — Lock the boundary & time

We used the ABS ASGS 2021 boundary for the City of Ipswich (LGA33960). “Now” = 2025. Fixing the boundary and date avoids suburb creep and version mismatch.

Step 2 — Map the bush the way scientists do

Queensland’s Regional Ecosystem (RE) maps show which native (tree/vegetation) communities sit where. We clipped REDD v13.1 / Remnant Vegetation 2021 to the LGA, then focused on Ipswich’s big players: ironbark–spotted-gum hills (12.9–10.2; 12.9–10.7), blue-gum floodplains (12.3.3), paperbark swamps (12.3.6) and river-fringing forests (12.3.7). Each RE spells out its dominant canopy species.

Step 3 — Turn hectares into tree counts

For each RE we converted area to trees using structure-based densities (e.g., woodland vs open forest), then apportioned stems to the species the RE describes as dominant. Sensitivity tests covered density and mix.

Step 4 — Add the urban layer you actually walk under

Street trees came from total road kilometres × a realistic “trees per planted kilometre”. Parks used scattered-tree densities by park type. Yard-heavy species (jacaranda, poinciana, lilly pillies, palms, citrus) used local occurrence signals to ground estimates.

Step 5 — Merge, rank, sanity-check

We summed the natural + street + park + yard trees for each species/group, then stress-tested assumptions: ±25% on density, ±10% on species mix, ±30% on yard factors. The headline didn’t budge — ironbarks + spotted gum + blue gum rule by area; urban favourites are visible but small in the LGA-wide totals.

What to keep in mind

  • These are ranges, not magic exact counts.
  • Urban favourites feel common because we live near them, but the LGA’s native hill and floodplain forests are vast — that’s where the numbers are.
  • At the margins (#9–#18), a place or two can swap without changing the story.
