Locations and overall extent of historical timber inventory conducted in 1924. The inventory was based on the Public Land Survey System, with individual quarter-quarter sections (red) as the observational unit for sampling. The dots represent Forest Inventory and Analysis plots that were surveyed between 2011 and 2018, which were used as the regional contemporary forest conditions in our analysis. They are colored based on whether black oaks (BO) were absent (blue) or present (orange) in the plot. Locations are superimposed on a topographic map provided by ESRI in ArcMap 10.7.1
