Quaking aspen is a common component of postdisturbance landscapes, in part because of its ability to regenerate via asexual suckers. Previously viewed as exceedingly rare in the western United States, sexual seedling establishment is increasingly seen as another important natural regeneration pathway for aspen, because sexual regeneration increases genetic diversity and facilitates long-distance dispersal. However, aspen seedling research is hampered by difficulties in visually distinguishing seedlings from suckers in the field, and few resources exist to guide managers and researchers. We present methods for distinguishing aspen seedlings from aspen suckers, suitable for use in field studies. Using these methods, we achieved 99 percent predictive accuracy in a recently burned area in southern Utah, although accuracy decreased to 90 percent following one summer’s growth, as seedlings and suckers became more similar in appearance.

在野外区分吸盘的白杨幼苗的方法

震动白杨是干扰后景观的常见组成部分,部分原因是它具有通过无性吮吸者再生的能力。以前在美国西部被视为极少见的有性苗木,越来越多地被视为白杨的另一个重要的自然再生途径,因为有性再生增加了遗传多样性并促进了远距离传播。然而,白杨幼苗的研究由于难以在野外用肉眼将幼苗与吸盘区分开来而受到阻碍,并且几乎没有资源可以指导管理人员和研究人员。我们提出了区分白杨幼苗与白杨吸盘的方法,适用于田间研究。使用这些方法,我们在犹他州南部最近被烧毁的地区实现了99%的预测准确性,
