About Slash Pine
Slash Pine (Pinus elliottii) is an introduced tree documented on Kauaʻi by Bishop Museum’s 2025 checklist and the 2026 Smithsonian checklist. Its checklist classification is naturalized; current extent is unassessed. Native to the southeastern United States, especially low, moist flatwoods and seasonally wet sites, and widely used in plantation forestry. Wind carries its winged seed from woody cones. Bishop Museum and Smithsonian document naturalized Kauaʻi occurrence, while a 1998 government inventory independently measured extensive planted stands.
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 27 plants under Pinus elliottii across 1 entries dated 1956. 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
- Habitats
- Not yet assessed
- Food and resource needs
- Not yet assessed
- Reproduction
- Separate pollen and seed cones form on the same tree. Wind pollination is followed by woody cone maturation over roughly two seasons and release of winged seeds; Kauaʻi-specific cone phenology, seed movement, and recruitment are unmeasured.
