Preface The IUCN Red List is the starting point for conservation! 2014 marks the 50th anniversary of the IUCN Red List. The IUCN Red List of Threatened Species™ has been assessing the conservation status of plants, fungi and animal species on a global scale for the past 50 years. Since its conception in 1964, the Red List has evolved to become the world’s most comprehensive information source on the extinction risk of animal, fungi and plant species. Far more than a list of species and their status, it is a powerful tool to inform and catalyze action among scientists, activists, and politicians. It is used by government agencies, wildlife departments, conservation-related non-governmental organizations (NGOs), natural resource planners, educational organizations, students, and the business community. The Red List process has become a massive enterprise involving the IUCN Global Species Program staff, partner organizations and experts in the IUCN Species Survival Commission and partner networks who compile the species information to make The IUCN Red List the indispensable product it is today. IUCN Bangladesh had published the fi rst Red List of Threatened Animals of Bangladesh in 2000. The list is being updated since December 2013 through a sub-project titled “Updating Species Red List of Bangladesh” under the “Strengthening Regional Cooperation for Wildlife Protection Project” (SRCWP) of the Bangladesh Forest Department which is funded by World Bank. As part of the IUCN Red List’s 50th anniversary campaign, Red List 50, IUCN Bangladesh Country Offi ce organized a day-long programme on 22 December 2014 at the Bangabandhu International Convention Center (BICC). The programme includes two technical sessions which participated by scientists, wildlife biologists, nature lovers, conservationists, students, media, policy makers, development partners, etc. The technical sessions highlighted research papers carried out by the individuals/institutions to uphold their contribution to enrich the knowledge of wildlife of Bangladesh in a wider context. This manuscript entitled “The Festschrift on the 50th Anniversary of The IUCN Red List of Threatened SpeciesTM” to commemorate this occasion contains keynote papers, full papers and abstracts that presented during the sessions of the programme. This is a fi rst of its kind of volume that compiled a wide range of research done in Bangladesh on wildlife diversity, conservation biology and policy. I would like to commend the authors for their contributions to the manuscript and for their commitment towards making this a reality. The papers have been reviewed by a panel of experts and have been revised and edited as per suggestions of the reviewers. The tireless efforts of the reviewers in making the papers up to the standard are gratefully acknowledged. Without their assistance this manuscript would not have been of the quality that it is now. I like to take this opportunity to express my sincere appreciation to all the members of Updating Species Red List of Bangladesh Project and all concerned people of publication work for publishing this manuscript to mark the 50th anniversary of the IUCN Red List. I would also express my gratitude to Ministry of Environment & Forest (MoEF), Chief Conservator of Forest (CCF) and other Forest Department offi cials for their vigorous support and collaboration. I hope this manuscript will help current researchers in fi nding historical research papers/abstracts in a one cover of volume in future.
