Comeau, Shilo. Lacreek National Wildlife Refuge 2004 Fall Trumpeter Swan Survey, 2004, pp. 1 - 7.
The annual fall trumpeter swan survey is conducted to determine production and distribution for a portion of the Interior Population of trumpeter swans in accordance with the Central Flyway and the Lacreek National Wildlife Refuge (hereafter Refuge) trumpeter swan management plans (1997 and 1982 respectively). Each plan outlines population objectives (VI-2 and A-1) and management strategies for monitoring population status, which at Lacreek includes aerial surveys. These surveys are part of a trumpeter swan monitoring program that spans over two decades.
