Island Conservation's mission is to prevent extinctions by removing invasive species from islands. The Tasman parakeet Cyanoramphus cookii is threatened by feral cats, rodents and by competition with introduced parrots. Unfortunately monitoring of numbers and impacts of invasive species on Tasman parakeets has ceased and there are fears that a major population crash may have occurred in recent years. Determining the population size of this cryptic species in its forested habitat has been problematic and further refinement of techniques is needed if accurate estimates of population size are to be made. This project is designed to "kick-start" a more comprehensive process to address the on-going decline of biodiversity on Norfolk Island and the potential extinction of one of the islands most charismatic species.

This will inform future management action, including how and where these invasive species interact with this threatened species, and will provide a baseline assessment of relative abundance necessary to determine population trends.
