NEMBA Category 2 (for caged birds); NEMBA Category 1b (feral birds)

Where in South Africa is it a problem?
Western Cape Province, Eastern Cape Province, KwaZulu-Natal Province, North West Province, Mpumalanga Province, and Gauteng Province.

How does it spread?
The pet trade is the only pathway by which rose-ringed parakeet is likely to establish feral populations.
