Trumpeter swan non-native Eurasian mute swan population who compete for habitat. One of the largest conservation sites for the trumpeter swan is located in Lois Hole Provincial Park. It is located adjacent to the renamed Trumpeter subdivision of Edmonton, Alberta within Big Lake. Joe Johnson, a biologist for the W.K. Kellogg Bird Sanctuary, part of Michigan State University’s Kellogg Biological Station, obtained trumpeter swans from Alaska for re-introduction to Michigan beginning in 1986. The population has grown via continued re-introductions and organic growth to 756 birds by 2015. The native swans have benefited from removal of non-native mute swans by the Michigan
