Leaf Area in the Clearcut Site at Harvard Forest 2010-2012

This dataset contributed to an estimate of leaf area by species at the Prospect Hill clearcut regeneration site, used in a publication to attribute measured changes in gross primary productivity over time to either changes in species composition and associated traits versus changes in total leaf area. The file reports data on leaf area by species from destructive harvest in select plots. It also reports leaf area and leaf weight from destructive harvest of the foliage of select individual species to characterize the vertical distribution of foliage for those species. Corresponding measurements of total plant area recorded with a LAI-2000 before and after harvest of this foliage is reported as well, useful for inferring the leaf versus stem/branch portions of light interception as needed for improved estimates of LAI with the light-interception method. Lastly, below we report the result of an August 2012 site-level survey of plant area index measured with the LAI-2000 and converted to leaf area index.
