Flowering Phenology And Abundance, Gothic, Co, Usa, 1973-Present

Prof. David Inouye has been collecting data on the abundance and timing of flowers that fall within permanent plots at the Rocky Mountain Biological Laboratory (RMBL), in Gothic, Colorado, USA, from 1973 to present. During the growing season, flowers of each species are counted approximately every other day, though in some years the start and/or end of flowering were missed, and data were not collected in 1978 and 1990. A core set of 23 2 x 2 m plots have been followed 1974-present (excluding 1978 and 1990), and additional plots have been added through the years (two in 1985, three in 1998, and two in 2004). Data are now collected in a total of 30 plots and up to 135 plant species have been recorded in the plots.美国科罗拉多州哥特镇落基山生物实验室（Rocky Mountain Biological Laboratory，RMBL）的David Inouye教授自1973年起至今，持续收集该实验室永久样地内各类花卉的丰度与开花时间数据。生长季期间，研究人员约每两日对各物种的开花个体数进行计数，但部分年份的开花始期和/或终期存在数据缺失，且1978年与1990年未开展数据采集工作。1974年起（1978、1990年除外），共有23个2×2米的核心样地被持续监测；后续研究逐年增设样地：1985年新增2个，1998年新增3个，2004年新增2个。当前该数据集共覆盖30个样地，累计记录的植物物种多达135种。
