About Crimson Bottlebrush

Crimson Bottlebrush (Melaleuca citrina) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to eastern and southeastern Australia in subtropical woodland and streamside vegetation. A 1980 forestry ledger documents Kauaʻi planting within the 1910–1960 forestry program; no species-specific year is available from the reviewed index; it does not establish current survival, reproduction, or naturalization.

Kauaʻi evidence

Taxonomic identity, tree form, diagnostic morphology and island occurrence use the linked reviewed sources. Historical planting, cultivation, naturalization and invasive status are separate. Generated imagery is not occurrence evidence. The 1918–1959 Kauaʻi reforestation working register records 24 plants under Callistemon citrinus across 1 entries dated 1931. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.

Kauaʻi occurrence and status

Kauaʻi occurrence: Recorded on Kauaʻi
Origin: Introduced
Conservation status: Not yet assessed
Evidence date: 2026-10-06
Evidence limits: Current survival on Kauaʻi, number of trees, occupied habitat, flowering or fruiting, recruitment, population trend, and ecological effects are all unconfirmed; no naturalization or invasive severity is inferred from the historical planting record.

Habitat and ecology

Habitats: Not yet assessed
Food and resource needs: Not yet assessed
Reproduction: Nectar-rich bottlebrush flowers are animal-pollinated; many fine seeds mature in persistent woody capsules. Kauaʻi flowering, pollinators, seed viability, dispersal, and recruitment are unknown.
Shelter: Not yet assessed
Growth form: Evergreen shrub or small tree

Threats and conservation

Monitoring: Not yet assessed
Data gaps: Current population extent and trajectory · Additional species-specific ecological and conservation sources
