Second Time Around?

There is a recent report (http://www.theguardian.com/environment/2013/sep/26/beaver-bison-european-species-comeback) on 37 European species that have been helped by conservationists to come back from the brink of extinction. The European bison, European beaver and the Wolf are included as success stories. Less successful has been attempts to 'save' the Iberian lynx. One thing that strikes me, however, is that all the species refered to are vertebrate 'mega stars', so it would have been nice to see some less obvious (but perhaps more environmentally crucial) animals and plants in the list.
