For the North Island kōkako, there has been a significant decline over the last 20 years. Management is reversing that trend in many areas.
Recovery plan
The Department of Conservation and community groups are working to boost kōkako numbers. For kōkako numbers to recover there needs to be:
- Ongoing control of predators using traps and poison
- Managing genetics by moving kōkako from different areas to breed with different birds
- Improving the habitat of kōkako by planting natives
- Bringing kōkako back to areas where they once lived.
Research
To ensure long-term survival of kōkako there needs to be a greater understanding of kōkako. Long term research projects will help increase knowledge of the species. So far research has shown that intensive management of introduced predators can result in a rapid increase in kōkako numbers.
Island populations
Pest free islands are the perfect sanctuary for native birds. Without predators, bird numbers can increase. These populations need to be managed with new birds brought in.
Birds from different areas have different genes and when they breed they produce offspring with different genes. This genetic variation keeps the population healthy. If the same birds always breed together then there is not enough mixing of genes and the gene pool becomes very small. This can lead to sickness and low reproductive rates.
Translocation
One method to increase kōkako numbers is to translocate or move birds from one area to another. This is done so that:
- birds can be taken to areas made safe by predator control
- birds can be reintroduced to areas where they once lived after predators have been removed
- birds from different areas can be brought together to breed and maintain a healthy mix of genes
You can help
Community involvement is important for kōkako survival. Volunteers can help:
- Survey kōkako to gain a better understanding of kōkako numbers in different areas
- Control predators by setting traps and maintaining bait lines
- Restoring kōkako habitat by planting natives
- Call 0800 DOC HOT (0800 362 468) immediately if you see anyone catching, harming or killing native wildlife.
When visiting forest areas 
- Only take dogs to areas that allow them, and keep them under control
- Check for pests when visiting pest-free islands
- Leave nesting birds alone
- Stick to the track
- Clean footwear and gear before entering a forest to avoid the possible spread of harmful micro-organisms
- Don’t leave rubbish
- Don’t feed birds
Other ways to help
- Get your dog trained in avian awareness.
- Volunteer to control predators and restore bird habitats in your local area
- Set predator traps on your property
- Put a bell on your cat's collar and feed it well.
