The heart of the project is protecting Orkney's native wildlife and the project's monitoring programme is focused on the species most likely to be affected by stoats. It has three aims:
- To monitor native wildlife to understand the impact of non-native stoats on native wildlife and the impact of eradicating stoats from Orkney
- To increase knowledge and enthusiasm for monitoring to help it continue in the long-term
- To provide opportunities for local residents and visitors to be involved through citizen science
Monitoring sites are spread throughout Mainland Orkney and smaller isles where there are no stoats for comparisons. Comparisons are also being made to historical data where available.
