Seed and ring width data from 'Climate drivers of seed production in Picea engelmannii and response to warming temperatures in the southern Rocky Mountains'

Seed production by Picea engelmannii was monitored at 13 plots distributed across an approximately 670 meter elevation gradient in the Fraser Experimental Forest near Fraser, Colorado. Seeds were collected annually between 1970 and 2010 from ten wire mesh seed traps located in each of the 13 plots. Annual plot level estimates of seed abundance were derived from an average value of the 10 traps. Data include plot level empty and sound seed abundance estimates as well as seasonal temperature and precipitation values obtained from gridded climate datasets. In 2011 tree cores were collected for approximately 15 canopy trees within each of the 13 seed plots and annual tree ring widths measured.
The main objectives were to quantify the temporal and spatial patterns of reproduction in Picea engelmannii and to determine the climatic factors driving inter-annual variability in reproductive effort.
