The conservation status of over 70 chameleons, plus another 250+ other lizard and snake species was assessed in a workshop organised by Madagasikara Voakajy and Conservation International from 24 to 28 January 2011. The workshop was facilitated by the IUCN and over 20 expert herpetologists took part. We are grateful to the Darwin Initiative, Conservation International and the Mohammed bin Zayed Species Conservation Fund for supporting the workshop.
