Dogs and cats can have a major negative impact on the breeding success of large terrestrial birds and other creatures. Cats, for example, catch a variety of small creatures, such as lizards, frogs, mice and small birds, reducing populations of these creatures and even causing them to become locally extinct. Free-ranging livestock, meanwhile, can do much damage to natural habitats through overgrazing, trampling and, in the case of pigs, predation on nests and small animals.
- Ensure your pets don’t roam freely in areas where birds are breeding or roosting.
- Restrict livestock to areas where they’re meant to graze.
- Feral (domesticated animals that have become wild) cats, dogs and pigs should be eradicated, but not with the careless use of poison.
- Discourage farm employees from keeping large numbers of pets.
Benefits to you
- Elimination of feral animals will help control the spread of animal diseases.
- In the case of feral pigs, elimination will also limit damage to crops.
- Control of dogs will help to prevent attacks on innocent people.
- An absence of feral (and domestic) cats will bring about the presence of a richer collection of small wildlife.
