The International Zoo Yearbook has dedicated three previous volumes to reptiles. The first was published in 1969 (Volume 9, also including amphibians) and the second in 1979 (Volume 19), and these focused mainly on breeding reports and husbandry for many reptile species that rarely reproduced in zoos and aquariums at that time. Today, some of these species breed regularly in zoological facilities while others still remain difficult to propagate under artificial conditions. In 1989, a third volume (Volume 28) was dedicated to reptiles (although it also included amphibians). Again, the focus was primarily on collection management in zoological facilities with a special emphasis on breeding success in selected species.
When comparing the articles that appeared in the previous three volumes with those that appear here in Volume 49, it becomes readily apparent that the herpetological specialism has developed a variety of methods to link work in zoos and aquariums with conservation programmes being carried out in the field. These two approaches, regarded as distinct in the past, will be blurred in the future.
More recently, the IUCN Species Survival Commission Conservation Breeding Specialist Group adopted the One Plan Approach, which promotes cooperation between ex situ (zoological) institutions and in situ (range-country) stakeholders in order to manage all populations of species using unified, integrated plans. The maintenance and breeding of rare reptiles are no longer a primary goal for zoological facilities. The ultimate goal is to support the conservation of reptiles in their wild, natural habitats, and various means by which to achieve those goals are reported within Volume 49 of the International Zoo Yearbook.
Another theme that runs through the Reptile Conservation section of Volume 49 is the fact that for field-conservation programmes to be successful, it is important to integrate local people who live within the range of the threatened species into the projects.
The second half of this volume has the regular contributions on developments in the zoo world.
