Charismatic island dwellers saved from extinction

Conservation action saved 16 bird species from extinction between 1994 and 2004.

Although they represent just 1.3% of the world’s threatened birds, these successes demonstrate that, given political will and resources, we have the knowledge and tools to turn back the tide of extinction.

In their paper How many bird extinctions have we prevented? (Oryx, July 2006), BirdLife authors Stuart Butchart, Alison Stattersfield and Nigel Collar explain how they identified these 16 cases: the first time anyone has attempted to quantify the results of global conservation action in this way for any group of organisms.

The majority had populations of fewer than 100 birds in 1994, with only four known breeding pairs of Chatham Island Taiko Pterodroma magentae, just four breeding female Norfolk Island Green Parrots Cyanoramphus cookie, and five pairs of Mauritius Parakeet Psittacula eques (three of which had bred without success).

  1. Ecology: Are Global Conservation Efforts Successful?
    Human actions affect ecosystems worldwide, leading to
    irreversible losses in biodiversity. These changes were faster in
    the past 50 years than at any time in human history, and this
    acceleration is projected to continue, despite diverse
    efforts to prevent these losses. Do these efforts make any
    measurable difference in the global…
