Where the same map sheet was surveyed more than once during the three surveys, only results from the most recent survey are presented. Regional survey reports are presented for 2005. Continental survey reports are presented for 2010 and 2015. Due to the large population expansion, Canadian RMP Trumpeter Swans are no…
