5200 |a"In 2001-2003, complete aerial counts of swans were carried out during mid-June(nesting) and early August (brood-rearing) in a number of study plots in the Mackenzie Delta Region. Plots were established in 21 treatment or development areas (where gas exploration activities had occurred) and 27 control or reference areas. The main long-term objective of the work is to assess the numbers and reproductive success of Tundra Swans at plots of the two types in the Mackenzie Delta region and, by extension, evaluate the potential effects of proposed development on migratory bird populations. This report describes baseline population parameters for Tundra Swans as they existed in 2001-03, evaluates whether any impacts of development have been so far detected, and presents recommendations for future work"--p. 2.
