About Cork Oak
Cork Oak (Quercus suber) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to the western Mediterranean region in temperate sclerophyll woodland. 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 60 plants under Quercus suber across 1 entries dated 1948. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.

Habitat and ecology

- Reproduction
- Wind pollination between male catkins and female flowers produces acorns, which may be dispersed by animals. Kauaʻi flowering, acorn maturation, viability, and recruitment are unknown.
