Abstract: On 12 points, with electric predator barriers, there were 0.84 duck nests per acre with a hatching rate of 60%. On 12 control points, there were 0.23 nests per acre with a hatching rate of 8%. On 9 islands where predators were removed, there were 851 nests in 1986 with 87% nest success. In 1984 and 1985, before predators were controlled, these islands contained 52 nests with 8% nest success. The management cost to produce hatched young on treated points was $7.13 compared with $0.33 for each hatched young on islands.
