The effectiveness of white flags as visual repellents to snow geese (Chen caerulescens) was evaluated.

At 7-day intervals for SV2 weeks, mean vegetation length and mean percentage vegetative cover were estimated for all fields. The results showed that grazing damage was significantly reduced in fields with flags. It is concluded that white plastic flags …
