NEON vegetation characterization data from multiple sites, 2015 - 2017

In advance of initiating sampling at each NEON site, surveys of plant presence, abundance and biomass were conducted in the Tower airshed. The data collected were used to 1) test measurement protocols, 2) evaluate effect of plot size biomass estimates, 3) generate initial species lists, and 4) select species for plant phenology observation. Data were collected by NEON personnel, within established Tower plots. Only three Tower plots at each site will be surveyed for diversity in full NEON Operations. See the NEON Site characterization reports for more details about this dataset.
