Download and view FrogLog 100.

Welcome to the 100th edition of FrogLog. A little over 20 years ago the first edition of FrogLog was published by the Declining Amphibian Populations Task Force (DAPTF). A free publication, FrogLog provided a summary of field studies, announcements, grant support, and recent publications. In August 2006 the 76th edition of FrogLog was published by the newly formed IUCN SSC Amphibian Specialist Group. Since then we have tried to build on the great work undertaken by the DAPTF and have continued to develop FrogLogto meet the needs of our members and the wider community interested in amphibian conservation and research.

With the current FrogLog format we are hoping to provide an insight into regional activities and provide opportunities for individuals and groups to tell their stories. FrogLog articles range from detailed project updates and notes on the ecology of species, to stories from the field, which often read like an adventure novel.

This edition is a prime example of what we are trying to achieve. The ASG Updates provide a general overview of some of the projects in which we are currently involved, specifically within the region of focus but also globally, allowing us to highlight some of the upcoming projects of our partners, such as Amphibian Ark’s “Leaping Ahead of Extinction” event this February 29th (see page 18).

The Regional Focus section was introduced to provide members an annual platform to publicize their inspiring efforts. In this South American edition we have updates from a number of groups from Argentina to Venezuela with several fantastic submissions from non-ASG members whose work we are proud to publish. The Global section provides further opportunity for individuals and groups to publicize their efforts throughout the year. In this edition we have articles from Costa Rica, China, and India to name but a few.

We hope that the development of FrogLog will continue to be dynamic and meet the needs of our members and the wider community and thank all those who have played a part in keeping FrogLog alive for the last 20 years. Here’s looking forward to the next 20!
