Abstract: The vegetation of the Sigatoka Sand Dunes is regarded as of considerable conservation significance because of the unique sand dune environment and the presence of many plant species that are uncommon in typical Fijian beach forests. The increasingly degraded and threatened status of the original native forest communities due to human disturbance was addressed by Kirkpatrick and Hassall (1981). This, plus the unique nature of the dunes, resulted in the designation of the site as a national park in 1989. Although it is apparent that impacts due to direct destruction of natural or semi-natural habitats have been reduced significantly since the establishment of the park, it is clear that plant invasion or succession has continued unabated, causing further changes in species composition and community structure. However, the geographical scale of the site, coupled with the temporal nature of plant communities in time and space and the diverse nature of the sand dune vegetation itself, makes it very difficult to perceive the nature of the vegetation changes and to pinpoint priority problems that need to be addressed to ensure the long-term survival of the remaining native species associations.
