Strawberry guava invasion

Names and classification

Record type

threat

Kauaʻi occurrence and status

Recorded state

Active / established

Threats and conservation

Pressure source

Psidium cattleyanum

Exposure pathway

Dense thicket formation and competition with native forest plants

Consequences

Reduced native recruitment and altered forest structure

Affected requirements

Native regeneration, forest structure and access for management

Susceptibility

Mesic and wet forest/riparian systems

Reversibility

Locally reversible with sustained control and native recovery; broad eradication not presently realistic

Early warning indicators

Percent cover; stem density; recruitment; spread front

Conservation interventions

Implementation limits

Magnitude, exposure and trend are not assumed uniform across Kauaʻi; local evidence governs.
