摘要

Determining at what scale to operate and how much cover is needed are important questions for winter habitat management of white-tailed deer, Odocoileus virginianus (Zimmermann, 1780), through logging. We used binary cover maps (reclassified forest vegetation maps) and windows of different sizes (0.2 km x 0.2 km, 0.5 km x 0.5 km, 1 km x 1 km, 2 km x 2 km, and 3 km x 3 km) to describe the relationship between deer density from an aerial survey and the proportion of balsam fir, Abies balsamea (L.) P. Mill., forest (BF) cover in a 270-km(2) block on Anticosti Island, Quebec. Maximum white-tailed deer densities reached were quite similar (31-34 deer/km(2)) irrespective of window size, except for the 3 km x 3 km window for which maximum density remained half lower. Density increased with the amount of BF cover and then reached a plateau above 60% or 70% (two smaller windows) or decreased above 50% or 60% (1 km x 1 km and 2 km x 2 km windows). Results confirm goals previously used for habitat management of deeryards. This new method allows greater flexibility in research applications for describing density-cover relationships because both scale and proportion of cover can be analysed simultaneously.
