驼鹿（Alces alces）的冬季浏览模式进行了研究，在北方安大略在1975年和1976年春季和夏季的三个割地。这三次割接的树龄为5至6年，面积为24至525公顷。 通过检查沿沿着选定的巡航线间隔25 m的2m × 4 m地块来确定浏览模式。 从大比例尺地图计算每个地块的覆盖距离。距离覆盖和浏览丰度之间没有相关性，驼鹿浏览是独立的食物分布。1975年，人们发现95%的浏览活动都局限在80米的范围内。 1976年，浏览使用倾向于更大，在一次割接中，显著使用延伸到距离覆盖物260米。 食物丰富和积雪深度达75厘米显然没有决定驼鹿的分布。
Winter browsing patterns by moose (Alces alces) were studied on three cutovers in northern Ontario during spring and summer of 1975 and 1976. The three cutovers were 5 to 6 years old and ranged from 24 to 525 ha in area. Browse patterns were determined by examining 2 m × 4 m plots spaced at 25 m intervals along selected cruise lines. The distance from cover for each plot was calculated from large scale maps. No correlation was found between distance from cover and browse abundance, and moose browsing was independent of food distribution. In 1975, it was found that 95% of all browsing activity was confined to within 80 m of cover. Browse use tended to be greater in 1976, with significant use extending as far as 260 m from cover in one cutover. Food abundance and snow depths up to 75 cm apparently did not determine moose distribution.
