World's Wildlife Populations Are Struggling Despite Global Pledges to Protect Biodiversity
Seven years ago, governments around the world pledged to achieve a "significant reduction" in the ongoing loss of biodiversity by 2010. Unfortunately, the latest IUCN report says that goal will not be met, and that the wildlife crisis is greater than the world's economic crisis.
The report analyses 44,838 species on the IUCN Red List and presents results by groups of species, geographical regions, and different habitats, such as marine, freshwater and terrestrial.
It shows 869 species are Extinct or Extinct the Wild and this figure rises to 1,159 if the 290 Critically Endangered species tagged as Possibly Extinct are included. Overall, a minimum of 16,928 species are threatened with extinction. Considering that only 2.7 percent of the 1.8 million described species have been analyzed, this number is a gross underestimate, but it does provide a useful snapshot of what is happening to all forms of life on Earth.
"The report makes for depressing reading,” says Craig Hilton Taylor, manager of the IUCN Red List Unit and co-editor. “It tells us that the extinction crisis is as bad, or even worse, than we believed. But it also shows the trends these species are following and is therefore an essential part of decision-making processes. In the run-up to 2010, the global community should use this report wisely to address the situation.”
Likely to make the outlook worse is climate change, the report points out.
After examining the biological characteristics of 17,000 species of birds, amphibians and reef building corals, the report found that a significant proportion of species that are currently not threatened with extinction are susceptible to climate change. This includes 30 percent of non-threatened birds, 51 percent of non-threatened corals and 41 percent of non-threatened amphibians, which all have traits that make them susceptible to climate change.
Still, there are success stories, and some involve habitat in the national parks. For instance, in 2008 the IUCN reclassified the black-footed ferret from "extinct in the wild" to "endangered" thanks to a recovery program overseen by the U.S. Fish and Wildlife Service. Badlands National Park has proved to be a good home for the ferrets, as has Wind Cave National Park. Additionally, when the focus is on amphibian diversity, the group points to the southeastern United States as "a global centre for amphibian diversity, being particularly rich in salamanders," and of course Great Smoky Mountains National Park is arguably the salamander capital of the world.
