The report is a comparative study between spruce plantations where 4 plants are treated with deer repellents and 4 plantations are untreated. The study aims to provide a base for the Forest Society's future decisions regarding the use of wildlife-repellents. The report indicates that wildlife-repellents work reasonably well for its purpose, the treated stocks were virtually untouched during the planting year and next year while the untreated stocks have been heavily grazed during these years. Growth difference between grazed plants and ungrazed plants found to be virtually non-existent (0, 01 m) of the treated stocks and 0, 07 m in the untreated plants. Because of the growth differences are so small between grazed and no grazed plants, it seems like the treatment of deer-repellent are unnecessary. Unless you know in particularly that the area has a specific problem whit severe deer-grazing.
