this is a complex effort by the WWF to estimate the impact on life taking in 14,200 population of 3,700 species of vertebrates ranging fro small frogs to very large whales
the biodiversity index went down 58% between 1970 and 2012. on current trends a 67% decrease can be expected by 2020
please see http://wwwf.panda.org it is now in their banner header and in their recent news items
they use panda.org for their home page
so declines continue despite all the efforts being made, without them things would be a lot worse
