Part F: Duration and costs
F.1 Duration and costs
Costs envisaged in implementing this plan are:
| Action | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 |
|---|---|---|---|---|---|
| Keep locations of populations confidential [1.1] | Continuing - nil cost | ||||
| Monitoring of visitor pressure and impact on Gannet Hill population [1.2] |
Regular and continuing Minimal cost |
||||
| Inclusion in all guidelines and specifications for environmental assessment and standards, particularly along the east coast [1.3] | Continuing - nil cost | ||||
| Pursue national park status for Ross Hill Gardens area and around South Pt [1.4] | Minimal cost | ||||
| Pursue national park status for areas associated with any populations located within the term of this plan [1.4] | Continuing - Minimal cost | ||||
| Consider need for listing on EPBC register of critical habitat, with update as new populations are located [1.5] | Continuing - Minimal cost | ||||
| Expand content about Asplenium listeri (and other listed plant species) in future national park management plans [1.6] | Minimal cost | ||||
| Update Ramsar Information Sheet and description of ecological character for The Dales [1.7] | Minimal cost | ||||
| Update Ramsar Information Sheet if population at Hosnie's Spring [1.7] | If/when relevant - Minimal cost | ||||
| Collection and collation of data about known locations and populations [2.1] | $4,000 | ||||
| Consider predictive models to assist location of additional populations [2.2] | Not known | ||||
| Survey of potential habitat for additional populations, especially east coast [3.1]; (actual timing depends on wet season) | $5,000 | ||||
| Examine the need for and potential of ex situ cultivation [3.2] | Not known | ||||
| Examine potential for (re)introduction of into additional east coast cliff-tops [3.3] | Not known | ||||
| Communication costs associated with annual evaluation by the recovery team |
Annual Minimal cost |

F.2 Resource allocation
Estimated costs assume that much of the work can be carried out by personnel on Christmas Island (i.e. no allowance is made for airfares and accommodation). Although some external assistance may be required in design of survey and documentation methods and in review of results, this may not need to be on-site.
Efficiencies may be gained by:
- combining the effort for actions 2.1 and 3.1 (combined cost about $7,000)
- ensuring that future versions of the Christmas Island National Park management plan incorporate actions arising from this recovery plan and from all others in force for the island
- integration of continued data collection with other Natural Heritage Trust programs and relevant environmental assessments on the island; and
- use of one recovery team on the island to implement and evaluate all recovery plans for threatened plant species and any relevant threat abatement plans.
For some actions in Years 3 to 5, likely costs are not known because they depend on the outcome of earlier efforts. For example, collation of data on known populations [2.1] may obviate the need for any additional expenditure on predictive models [2.2], or else may provide a firmer indication of the likely complexity of such models and what allocation may be required. Similarly, examination of potential for (re)introduction [3.3] may depend entirely on the outcome of examination of ex situ cultivation [3.2]. Such costings should be developed as the work of the recovery team progresses to Year 3.
Items shown as 'minimal cost' relate almost entirely to the national park area and would in most cases be expected to be contributed by Parks Australia.
