As the first experiment of its kind anywhere in the world, trial and error are key elements of the Trust’s 500-year journey.
To date, the Trust has demonstrated that:
- Fencing is a viable option for protection of threatened species on the mainland but requires ongoing vigilance to ensure that biosecurity is not compromised.
- Multi-species eradication is feasible but requires careful planning and monitoring for success.
- Mouse control on an ongoing basis is feasible without compromising the ecosystem
- Threatened species can be successfully restored to the mainland but require meticulous planning to minimise risks during transfer, and monitoring after release to a) determine whether or not the transfer has been successful and b) identify management options required to minimise dispersal and increase the chance of establishing self-sustaining populations.
- Some species will successfully spread into urban backyards but the attraction of exotic plants in backyards to other more vulnerable species (such as hihi) may affect the viability of populations of these species.
- A major eco-restoration project can also operate as a successful tourist attraction. In fact, engaging visitors through education and practical advice is necessary to ensure long term viability of the project.
- An urban site provides accessible educational and advocacy opportunities.
- Success can inspire and generate interest in similar projects elsewhere.
- Community involvement is critical to the success of a private conservation initiative.
