Flowers were counted within 30 2 x 2 m plots (120 m²) every two days. <b><i>may.to.july.precip.cm</i></b> is the amount of precipitation (snow and rain) from May 1 through to the end of July in cm water content (measured at the Rocky Mountain Biological Laboratory, RMBL). <i><b>snowmelt.doy</b></i> is the day of year that a 5 x 5 m plot was bare of snow.</p><p><br></p><p><b>Longterm_climate_floral_data.csv</b><br></p><p><br></p><p>This file has the data used to examine long-term trends in the climate and floral variables, 1974-2016. <i><b>snowmelt.doy</b></i> is the day of year that a 5 x 5 m plot was bare of snow. <b><i>may.to.july.precip.cm</i></b> is the amount of precipitation (snow and rain) from May 1 through to the end of July in cm water content (measured at Crested Butte). <i><b>floral.sum</b></i> is the sum of flowers from first flower accumulated to 80% of the season's total flower count. <b><i>number.floral.days</i></b> is the number of days above a low flower threshold of 0.75 flowers/m² (or 3 flowers per 2 x 2 m plot). Flowers were counted within 23 2 x 2 m plots (92 m²) every two days. There are separate floral variables for the three bumble bee species.</p><p><br></p><p>Please see the original paper for additional details.</p>
