The effectiveness of white flags as visual repellents to snow geese (Chen caerulescens) was evaluated. Twelve fields, each 10.12 ha (25 acres) in area, with snow goose damage, were located and proximity was used to create six pairs. Within each pair, one field was selected randomly for treatment (one white plastic flag per acre) and the other served as a control. 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 …

White-tailed deer (Odocoileus spp.) overpopulate many areas of the United States. Browse damage to agricultural crops, forest regeneration and landscaping can be severe. Human and animal health also arc threatened by Lyme disease, which is spread by the deer tick (Ixodes dammini). Although sterilants to reduce and/or slow the growth of deer populations and vaccines against Lyme disease may soon become available, efficient and economical techniques to inoculate large numbers of deer have not been developed. Oral baits represent one promising possibility. In experiment 1, salt blocks and several olfactory lures were evaluated as potential lures for use in deer …
