Palatability of Anispray-treated white spruce to snowshoe hares

Anispray, a foliar spray, is a relatively new chemical product used to deter herbivore browsing. White spruce (Picea glauca (Moench) Voss) trees treated with concentrations of Anispray ranging from 25 to 100% sustained as much browsing damage as untreated trees by snowshoe hares (Lepus americanus Erxleben). Damage levels were similar for Anispray-treated and untreated controls in both preference and acceptability experiments. More research is required to develop and implement silvicultural practices, such as the use of chemical repellents, to reduce damage to reforested trees by herbivores
