Part D: Objectives, performance criteria and actions
D.1 Recovery objectives, timelines and performance criteria
The overall goal is to improve the conservation status of the species.
We will know we have achieved this when at least one of the parameters that warrant the conservation status of critically endangered is improved sufficiently to consider an improved status of endangered (or better). This may not be achieved within the life of this plan.
Specific objectives to advance this goal within the life of the plan include:
| Objectives | Performance criteria | Timeline |
|---|---|---|
| Objective 1: To abate and avert threats to the species | No population of the species is impacted by a threatening process | Review and assess annually. |
| Objective 2: To improve knowledge of factors in the restricted distribution of the species | A comprehensive list of environmental factors (physical and biological) and/or a predictive model assist(s) location of additional populations | Review annually; assess at the end of five years |
| Objective 3: To increase the number of known occurrences | At least one additional population (or an enlarged population) of the species has been located in the wild | Review annually; assess at the end of five years |
D.2 Evaluation of success or failure
Performance will be evaluated annually, and assessed overall after five years as part of revising this plan, by a recovery team comprising representatives of Commonwealth agencies and community interests, supported by independent scientific advice.
The proposed member organisations include:
- Parks Australia North, Department of the Environment & Heritage
- Shire of Christmas Island
- Island Care Inc
- Department of Transport & Regional Services
- Australian National Herbarium, Department of the Environment & Heritage
- Christmas Island Phosphates
D.3 Actions to achieve objectives
Within the life of this plan:
| No. | Action | Suggested timing |
|---|---|---|
| Objective 1: To abate and avert threats to the species | ||
| 1.1 | Keep locations of populations confidential | Continuing |
| 1.2 | Monitor visitor pressure and impact on Gannet Hill population | Continuing |
| 1.3 | Ensure inclusion of Asplenium listeri in all guidelines and specifications for environmental assessment and standards, particularly along the east coast | Continuing |
| 1.4 | Pursue national park status for the Ross Hill Gardens area and around South Point, and other areas related to populations of Asplenium listeri that are located within the term of this plan | Initially by Year 3; then continuing |
| 1.5 | Consider need for listing on the EPBC Register of Critical Habitat to strengthen legal protection, with update as new populations are located | By Year 2; then continuing |
| 1.6 | Expand content about Asplenium listeri (and other listed plant species) in future national park management plans with specific reference to recovery plans and relevant threat abatement plans (keeping precise locations confidential) | Next revision - 2007/8 |
| 1.7 | For the population at The Dales, and if a population is located at Hosnie's Spring, update the relevant Ramsar Information Sheet and description of ecological character to ensure the most robust protective framework under the EPBC Act | The Dales - Year 1; Hosnie's Spring - as soon as relevant |
| Objective 2: To improve knowledge of factors in the restricted distribution of the species | ||
| 2.1 | Survey all known occurrences of Asplenium listeri to compile a comprehensive list of environmental factors (physical and biological) and base data (including photographic) for population monitoring | Year 1 |
| 2.2 | Consider use of the above to develop predictive models to assist location of additional populations | By Year 3 |
| Objective 3: To increase the number of known occurrences | ||
| 3.1 | Survey potential habitat for more populations, with focus on the east coast, including Hosnie's Spring (following a wet season) | By Year 2 |
| 3.2 | Examine the need for and potential of ex situ cultivation | Year 2 |
| 3.3 | Examine potential for (re)introduction of Asplenium listeri into additional east coast terrace cliff-tops | By Year 5 for review of this plan |
