Major shortfalls identified in marine conservation

2012.10.23 L OSPREY Papua credit XL Catlin Seaview SurveyA new study says that more than 17,000 marine species worldwide remain largely unprotected, with the U.S. among the bottom in supporting formal marine protected areas (MPAs) that could safeguard marine biodiversity.

The study, which is the first comprehensive assessment of protected areas coverage on marine life, appears in the international journal Scientific Reports. Authors include scientists from University of Queensland, the ARC Centre of Excellence for Environmental Decisions (CEED), UC Santa Barbara, the National Center for Ecological Analysis and Synthesis, Imperial College London and the Wildlife Conservation Society.

The authors looked at the ranges of some 17,348 species of marine life, including whales, sharks rays and fish, and found that 97.4 percent have less than 10 percent of their range represented in marine protected areas. Nations with the largest number of “gap species” or species whose range lie entirely outside of protected areas include the U.S., Canada, and Brazil.

Despite these dismal results, the authors say the study underscores opportunities to achieve goals set by the Convention on Biological Diversity to protect 10 percent of marine biodiversity by 2020. For example, the majority of species that were considered very poorly represented (less than two percent of their range found in marine protected areas) are found in exclusive economic zones. This suggests an important role for particular nations to better protect biodiversity.
