NEON vegetation characterization data from multiple sites, 2015 - 2017

All diversity surveys were conducted within the nested subplot 'Peet plot' design, species abundance was reported as percent cover within one to four 1 m2 sampling areas in each plot; species presence/absence for all additional species was reported within the 10-100 m2 subplot. Data were collected according to the same protocol used for the plant diversity data product but without measurement of height, potentially fewer cover classifications for variables other than vascular plants, and only one of the larger sampling areas (10 m2 or 100 m2) was used to search for novel species not found in the 1 m2 area assessed for percent cover.
