路边点计数通常用于大型调查，以增加样本数量。我们研究了谢南多厄国家公园在路边和非路边（200米和400米）点计数中检测到的物种差异。我们还比较了前3分钟检测到的物种列表和10分钟检测到的物种列表，以寻找潜在的物种偏差。81对路边和非路边的统计结果表明，路边的边缘物种数量较多，而非边缘森林物种数量较少。由于边缘种的增加，在路边点检测到更多的个体和物种。在10分钟内检测到的物种中，有65%是在前3分钟内记录的。
Roadside point counts are generally used for large surveys to increase the number of samples. We examined differences in species detected from roadside versus off-road (200-m and 400-m) point counts in the Shenandoah National Park. We also compared the list of species detected in the first 3 minutes to those detected in 10 minutes for potential species biases. Results from 81 paired roadside and off-road counts indicated that roadside counts had higher numbers of several edge species but did not have lower numbers of nonedge forest species. More individuals and species were detected from roadside points because of this increase in edge species. Sixty-five percent of the species detected in 10 minutes were recorded in the first 3 minutes.
