Summary: | This report summarizes population status and trends for 19 populations of Arctic seabirds. It is compiled as an input to the 2012 African-Eurasian Waterbird Agreement (AEWA) Report on the Conservation Status of Migratory Birds in the Agreement Area (abbreviated Conservation Status Report, CSR) being prepared by Wetlands International. The previous CSR report (CSR4) was published in 2008 and contained no detailed information of the status and trends of the Arctic seabird population analysed in this report. Thus, this is the first effort to summarize status and trends of Arctic seabirds in the agreement area. The report format including the tables are following AEWA CSR conventions, i.e., population sizes are expressed in individuals and trend calculations and status categories are based on AEWA guidelines. The AEWA agreement text, Action Plan and previous CRS Reports are available at: www.unep-aewa.org Abundance estimates have largely been based on counts of breeding birds or occupied nests in colonies, which is the most usually applied method of censusing colonial seabirds. Numbers reported as pairs or occupied nests have been multiplied by three to get the number of individuals. Trends have been calculated using published data from national monitoring programs and national censuses, as well as some previously unpublished data from national experts. |
