This website and its predecessor have benefited from the assistance of many people. As the compiler of this database my job is quite easy most of the time. Data entry accounts for most of the work, while the rest of my time is split between web design and getting hold of the literature. On all these fronts I have been wonderfully accomodated by those far more knowledgeable than myself.


The Sixth Extinction and Vanishing Flora forums

I am particularly indebted to the members of the Sixth Mass Extinction forum and the Vanishing Flora forum for providing such a stimulating environment in which to discuss recently extinct species and subspecies, domestic breeds and cultivated varieties. And for sharing their knowledge of rare and rediscovered species and subspecies. Peter Maas, Melanie Nayyal, Alexander "Alex" Lang, Francisco "Frank" Godino, Sebastian, Sebbe, RSN, amongthylacines, baghira, koeiyabe, simontonge (Simon Tonge) and the rest of the members have willingly shared their immense knowledge with me over the years. May the forum stick around for many more years yet!

Krystal Tolley of the IUCN Chameleon Specialist Group for answering my enquiries into the possibility of there being any recently extinct chameleons. Bruce Collette of the IUCN Tuna and Billfish Specialist Group for answering my queries into recently extinct tuna and billfish.

Help with web design

The original version of this database was started over at in 2010. Since that time the database has grown and grown, thanks in no small part to that initial enviroment and the features provided therein by Dave and Trish. The current website is the planned permanent home of REPAD, built using the open source CMS Joomla! Needless to say I owe a great deal of thanks to all those involved with the Joomla! project who have made it what it is today. I see a bright future for both of us. I have also benefited greatly from the official Joomla forum.
