In the 18 years since the status of the entire Australian bird fauna was first reviewed substantial funds have been spent on their conservation. This project will review the conservation actions directed at birds identifying characteristics of programs that effect success. We will compare conservation trajectories not just with the biological characteristics of birds but also with the social economic and institutional environment in which they live. The project will also undertake the first re-assessment of the status of all Australian bird subspecies since 2000 using a wiki-based review system. Ultimately the project should help guide the allocation of resources to threatened bird conservation to maximize effectiveness and efficiency.
