Featured Study
Sus caledonia: Extinction, Myth & Reintroduction
Haggis Reintroduction Biology Programme Sus caledonia
This study represents the first structured ecological and behavioural investigation of S. caledonia under conservation management.
Research Aim
To evaluate whether:
- Haggis can breed successfully in a semi-natural captive environment
- Captive-born offspring can be reintroduced to the wild with high survival and behavioural competence
Study Design
- Study period: 2019–2024
- Founding population: 20 mature Highland haggis (14 females, 6 males)
- Habitat: 9 acres of mixed Scots Pine woodland and heather moorland
- Monitoring methods:
- 250 motion-sensor remote cameras
- Thermal drone surveys
- Observation hides
- GPS tracking collars Sus caledonia
The project followed ethical review procedures, welfare oversight, and conservation best practice for species reintroduction.
Key Biological Findings
Breeding Success
- Stable captive reproduction over five years
- Mean productivity: ~25 haglets per year
- Natural maternal care and social structures retained Sus caledonia
Behaviour & Social Structure
- Female-led social groups (“cèilidh”) maintained
- Natural dispersal patterns observed in males
- No evidence of behavioural maladaptation in captivity Sus caledonia
Reintroduction Outcomes
- 72 haglets released at 2 years of age
- Integration into wild social groupings observed
- Mortality limited to:
- Road traffic incidents (2)
- Respiratory disease (7)
- 10 collar losses (common in wildlife telemetry) Sus caledonia
These results indicate strong post-release adaptation and support captive breeding as a viable conservation strategy.
Conservation Significance
The programme demonstrates that:
- Semi-natural captive systems can preserve wild behaviours
- Maternal learning plays a major role in post-release survival
- Reintroduction of S. caledonia is biologically feasible
This provides a framework for future recovery of additional haggis subspecies.
