Evaluating protected area effectiveness using bird lists in the Australian Wet Tropics

Protected areas in the Wet Tropics of Queensland, Australia, appear to offer better habitat for most endemic bird species compared to unprotected areas, but they do not significantly improve their long-term survival. Using a novel approach called list-length analysis (LLA), researchers estimated population trends of 21 endemic bird species from volunteer-collected data. The study found that while 16 species were more likely to be recorded in protected areas and the prevalence of most species has remained stable since 1998, there was no significant difference in their long-term survival between protected and unprotected areas, provided forests outside protected zones remain intact. This suggests that citizen-collected data can effectively inform conservation decisions when formal data is scarce.
