The effects of human disturbance on colonial nesting waterbirds with recommendations for their management at Last Mountain Lake / Dennis R. Jurick.: CW69-26/85-4E-PDF

"Last Mountain Lake (LML), historically important to birds, is a critical area for breeding, feeding and staging of colonial waterbirds. Of 13 colonial species recorded breeding at LML, ten presently nest there. Fewer breeding species and reduced frequency of breeding of colonial birds there since the 1950s have been attributed, in part, to human disturbance. Recreational activities have steadily increased particularly since the establishment of the Regional Park in 1961. White Pelicans, which did not breed at LML from 1973 to 1983, successfully nested there in 1984 when low water levels resulted in increased nesting space on the islands and decreased boating activity. A literature review revealed that human disturbance of colonial nesting waterbirds results in overall reduced productivity and abandonment of traditional nesting sites, and that restrictive measures and public education can help protect colonial nesting waterbirds. Recommendations for protecting colonial waterbirds at LML include an inventory of important breeding, feeding and loafing areas; studies on toxic chemical residues in breeding colonial waterbirds at LML; restricted access to known sensitive breeding sites; and public education"--Abstract.
