I am looking for any references or lists that cover all species that has been successfully saved by conservation measures (not just by zoos). I realise that there are plenty of articles on the internet and books written about specific examples (usually the famous ones like california condors or black robins) or they may cover a range of species. However I have been unable to locate a list which covers all species. I'm particularly interested in minimum number of individuals prior to their comeback - the mauritius kestrel being probably the most spectacular rise from 4 individuals. Larger animals seem to be relatively easy to search information on, but inverts and fish are pretty sparse for info. At this stage I am not particularly interested in species where no conservation program is in place, or the conservation strategy is not working successfully. Species that fit this category (in my mind) would include northern white rhino, sumatran rhino, saola or yangtze softshell turtle. Aside from the information that I have already gleaned does anybody have a list of which Partula species were brought into captivity and what the original populations were? I already have formed a preliminary list of about 60 odd species (where the population dropped to below 100 individuals), but there are definitely more that could be added.
