The effective management of threatened flora: Lessons from the case of Ziera 'prostrata' ms

The endangered plant Zieria 'prostrata' ms is known from only four headlands along three kilometres of the north coast of New South Wales, Australia. Given its restricted range and small population sizes, Zieria 'prostata' has been the subject of extensive management and research for almost a decade. In this paper, we review the history of management and research actions undertaken on Z. prostrata and evaluate their practical outcomes. By revisiting past management and research actions, and assessing their outcomes, we can learn much about the effective management and recovery of threatened flora. This review highlights five valuable lessons. First, effective survey is a priority for many rare plants. Second, accurate information and documentation are essential for effective conservation. Third, critical evaluation of the need for ex-situ conservation is necessary. Fourth, critical evaluation of the need for population enhancement and the most effective methods by which this can be achieved is a high priority. Fifth, adequate guidance of all those involved in recovery implementation is vital.
