Description Phenological observations of plant flowering patterns provide useful information for studying the ecological impact of global climate change over long-term periods. However, the long-term data sets with which meaningful comparisons can be made are rare, especially in the less-populated Northern Great Plains region of North America. Here we present the observations of first-flowering time of native and nonnative plant species in North Dakota and Minnesota over the course of 51 years in the last century. Orin A. Stevens recorded the first-flowering time of 753 species in the vicinity of Fargo, North Dakota, USA, and throughout North Dakota from 1910 to 1961. These data offer baseline indications of both the timing of first flowering and the presence/absence for a wide variety of plants in a region of North America with a relatively short growing season. <i>Key words: climate change; flowering time; Great Plains; phenology; tallgrass prairie.</i>

数据集说明：植物开花模式的物候观测数据，可为长期研究全球气候变化的生态影响提供重要参考。然而，可用于开展有效对比的长期观测数据集较为稀缺，尤其是在北美北大平原这类人口相对稀少的区域。本数据集收录了20世纪51年间，美国北达科他州与明尼苏达州境内本土及外来植物物种的首次开花时间观测记录。Orin A. Stevens于1910年至1961年间，在美国北达科他州法戈市周边及全州范围内，记录了753个物种的首次开花时间。这些数据可为北美生长季相对较短的区域内，各类植物的首次开花时间及物种存在与否提供基准参照。<i>关键词：气候变化；开花时间；大平原；物候学（phenology）；高草草原。</i>
