However, its success in helping species recover leaves a lot to be desired. Out of the thousands of species that have been listed by the ESA in the past 48 years, only 54 have recovered to the point where they no longer need protection. A new study, published in the journal PLOS ONE, examines why so few species have recovered successfully.

The study -- led by Erich Eberhard from Columbia University's Department of Ecology, Evolution, and Environmental Biology, and co-authored by scholars at Princeton University -- paints a grim picture. They find that most species are not receiving protection until their populations are precariously small, dimming their prospects of recovery.
