“…They detected snowshoe hare avoidance of selenate ions (Se0 4 ), but only at concentration levels toxic to Douglas-fir. Allan et al (1984), subsequently reported success in using sodium selenite (Se0 3 ) at subphytotoxic levels to reduce black-tailed deer browsing for a single season. However, the authors are unaware of any product that has emerged using sodium selenite as a systemic repellent.…”

Deer (Odocoileus spp.) occur across the United States and provide many desirable recreational and aesthetic opportunities. Unfortunately, deer foraging, particularly where population densities are high, can negatively impact agricultural resources or damage ornamental plants . Repellents are often regarded as a desirable approach to limit deer browsing. Although many products are marketed for use as repellents, the efficacy of these products in actually reducing deer browsing is varied. This paper reviews the results from efficacy tests we have conducted at the NWRC Olympia Field Station over the past several years as well as repellent work conducted by others. General efficacies of delivery systems and active ingredients incorporated in a variety of products are compared. Generally, products which have repeatedly demonstrated good efficacy in our trials are those products that produce sulfurous odors . These products have significantly reduced deer browsing for 8 to 12 weeks.

“…In the autumn preceding this study, around 85 deer were removed from adjacent Nerstrand Big Woods State Park (J. Vorland, personal communication). Other possible alternatives for decreasing the levels of deer browsing are electric fences, topical applications of predator urines, and time‐release selenium tablets (Allan et al 1984;George et al 1991;Swihart et al 1991).…”

“…Actively planting seedlings on abandoned farmland or other previously forested areas is aimed at speeding up natural succession. A number of factors, such as fire, disease, competitive vegetation, and drought, can influence the success of reforestation projects (Allan et al 1984). Some studies suggest that animal damage from deer, mice, and rabbits may be a key impediment to forest restoration projects (Crouch & Paulson 1968); but there is little documented evidence.…”

Effects of Deer Browsing, Fabric Mats, and Tree Shelters on Quercus rubra Seedlings

We examined the effects of deer browsing, fabric mats, and tree shelters on the growth and survival of Quercus rubra (northern red oak) seedlings planted as part of a reforestation project in southcentral Minnesota. Browsing by white‐tailed deer occurred on 68.6% of the seedlings growing without tree shelters, whereas only 3.6% of the trees were browsed by mice or voles and 2.5% were browsed by rabbits. Fabric mats, used to control competition from herbaceous plants for roughly half of the seedlings included in the study, had a detrimental effect overall. Seedlings grown with mats had a greater frequency of deer browsing and a greater chance of dying than seedlings grown without mats. Stem height for seedlings browsed by deer was less overall than for nonbrowsed seedlings, although this pattern varied with use of fabric mats and plot location. The use of plastic tree shelters effectively prevented deer browsing and reduced the mortality rate from 34.6% to 3.2%. Our results indicate that fabric mats should not be used in restoration projects with large deer populations. They also suggest that planting seedlings away from existing forest edges and using seedling protection measures such as tree shelters will increase seedling survival and growth in future restoration projects.

Use of predator odors to protect chick-peas from predation by laboratory and wild mice

Synthetic stoat odor (3-propyl-1,2-dithiolane and 2-propylthietane) and fox fecal odor (2,5-dihydro-2,4,5-trimethylthiazoline) at various concentrations were applied to chick-peas (Cicer arietinum) at sowing in an investigation aimed at reducing damage caused by house mice (Mus musculus). Stoat odor at 10% concentration exerted a measure of protection, as did 1% fox odor against predation by laboratory mice. Wild mice were less affected by synthetic predator odor and appeared to have a shorter memory for it. Laboratory mice cannot be regarded as surrogate wild mice, when used in experimental situations such as those employed here.
