Vascular Flora Surveys of Permanent Plots at the Harvard Farm at Harvard Forest since 2015

The objectives of this study were to: (1) Determine the species richness and cover of vascular flora in 27 permanent plots at the Harvard Farm (established in HF236). (2) Track any changes in species richness and species dominance in the plant communities at each plot over time. (3) Observe any changes in invasive species richness and cover over time. (4) Identify differences between plant community composition of plots in constant grazing, rotational grazing, and mowing areas. These data were collected by Harvard Forest interns and may include some misidentifications, but they should be considered accurate for larger scale analyses of changes in the density of growth forms and invasive species. For more accurate species-level information, please see data collected every five years by Glenn Motzkin (HF236 with data from 2014 and 2019).
