Without their active support and participation in the census, collecting and submitting the count data over these last years, it would not have been possible to collate this wealth of information and produce this report. The list of participants is held by the coordinators. In addition, we aknowledge counts provided by Igor Fefelov in Russia, Glenn McKinlay in Palau and the China Coastal Waterbird Census team in coordination with Vivian Fu. An important element of the Asian Waterbird Census is that it works in partnership with many existing national waterbird census programmes. The synthesis of the count data at the flyway and regional level provides added value back to the national count programmes as it gives the larger geographic overview of the status of populations and species. We thank and greatly appreciate efforts of all country and sub-country AWC Coordinators (current and past) for all their hard work and effort in coordinating and promoting the counts, including: Dan Weller and Golo Mauer (BirdLife Australia), Enam Ul Haque (Bangladesh Bird Club), Sherub Sherub (Ugyen Wangchuck Institute for Conservation & Environment, Bhutan), Shirley Hee (Panaga Natural History Society, Brunei Darussalam), Hong Chamnan (Wildlife Conservation Society, Cambodia), Lu Yong (Wetlands International – China), Yu Yat Tung (Hong Kong Bird Watching Society), Woei-horng Fang (Chinese Wild Bird Federation, Taiwan), Da-Li Lin (Taiwan New Year Bird Count), Raju Kasambe and Asad Rahmani (Bombay Natural History Society, India), Yus Rusila Noor (Wetlands International Indonesia Programme), Kaori Tsujita and Makiko Yanagiya, Naoki AMAKO (Ministry of the Environment, Japan), Jin Han Kim and Hwa-Jung Kim (National Institute of Biological Resources, Republic of Korea), Yeap Chin Aik (Malaysian Nature Society), Gombobaatar Sundev (Mongolian Ornithological Society), Thet Zaw Naing & Thein Aung (Myanmar Bird and Nature Society), Hem Sagar Baral (Himalayan Nature, Nepal), David Melville (Ornithological Society of New Zealand), Umeed Khalid (Ministry of Climate Change, Pakistan), Anson Tagtag and Carlo Custodio (DENR, the Philippines), Lim Kim Keang (Nature Soceity, Singapore), Udaya Sirivardana and Deepal Warakagoda (Ceylon Bird Club, Sri Lanka), Krairat Eiamampai and Budsabong Kanchanasaka (National Parks, Wildlife and Plant Conservation Department, Thailand), Thattaya Bidayabha, Philip Round, Ingkayut Saar and Wicha Narungsri (Bird Conservation Society of Thailand), and Le Trong Trai (Viet Nature Conservation Centre).
