7. Implementation

Table 1 outlines the implementation of recovery actions specified in this Plan for the period of five years from publication.

8. Social and Economic Consequences

The social and economic consequences of implementing this Plan are minimal, given the restricted distribution of the species. None of the species occur on land suitable for any form of agriculture. Restriction of mining of rhyolite on Box Range farm may cause the loss of some income to the landowner. Due to the extremely rocky and steep nature of the habitat occupied by Z. formosa, it is unlikely that the presence of the species will impose major constraints to likely proposals for the siting and construction of dwellings on these rural residential blocks.

9. Biodiversity Benefits

The protection of these three species will in turn protect the rock outcrop communities in which they occur. The shrub communities that occur on rhyolite rock outcrops on the NSW South Coast are uncommon and localised and often also support other rare or threatened species.

10. Preparation Details

This Recovery Plan was prepared by John Briggs and Genevieve Wright, Threatened Species Unit, NPWS Southern Directorate, in consultation with the owners of the land on which these species occur. The Plan was edited by Michael Saxon (NPWS).

11. Review Date

In relation to its status as the State-endorsed Recovery Plan for Zieria formosa, Zieria buxijugum and Zieria parrisiae, any major changes to this Recovery Plan will require the revised Plan to be placed on public exhibition in NSW and re-approval by the NSW Minister for the Environment. The NPWS or Environment Australia should be contacted if it is believed any change to the Recovery Plan or to the Recovery Program should be considered. This Recovery Plan is to be formally reviewed by the NPWS in conjunction with the landowners within five years from the date of its publication.

15. Costing Explanations

Where fund source is listed as Cash, funding will be sought from sources such as Natural Heritage Trust, industry sponsors, the NSW State Biodiversity Program and NPWS annual provisions for implementation of threatened species programs.

Salary for 'in-kind' contributions is calculated at $350 per day, which includes officer salary and on-costs, provision of office space, vehicles, administration support and staff management.

1Actions already approved for funding from the Commonwealth Natural Heritage Trust Endangered Species Program.
♦This money will only be required if the results of Action 3.1 indicate that ex-situ conservation measures are required.
* Priority ratings as defined by Commonwealth Recovery Plan guidelines: 1 - action critical to prevent extinction, 2 - action prevents negative impact short of extinction,
^Feasibility assessment reflects estimated chance of success of the action on a scale of 0-100%.
