Cook M. 1990. Field Survey of Proposed Mining Sites on the Malaspina Forelands. Mullen, Kit, Mary Beth Cook and Jim Thorne
Two types of surveys: population and productivity. Population surveys: flown between Aug. 15-31. Survey requires 1 primary observer, 2 secondary observers, 1 pilot. Primary observer tracks flight path on survey maps, observes swans, records numbers, location, and age composition (adult/cygnet). Secondary observers and pilot search for swans. Productivity surveys: two flights, first one to locate occupied nests in early June; second flight flown Aug. 15-31 to document reproductive success. (Data collected: June 4, August 18, 1993; June 5, August 22, 24, 1994)
