Across the country, public land managers make hundreds of decisions each year that influence landscapes and ecosystems within the lands they manage. Many of these decisions involve vegetation manipulations known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. Data on these land treatments historically have been stored at local offices and gathering information across large spatial areas was difficult. These valuable data needed to be centralized and stored for Federal agencies involved in land treatments because these data are useful to land managers for policy and management and to scientists for developing...

This data release consists of historical borehole geophysical data collected by various entities and digitally recreated by the U.S. Geological Survey to characterize the physical properties of the subsurface in the Mississippi Alluvial Plain from Louisiana to Missouri. The geophysical log data were collected by different Federal, state, and local agencies throughout the area, and were obtained from two sources: Hart and Clark (2008) or the Mississippi Department of Environmental Quality (MDEQ) website. The log data generally consisted of either scanned .jpg or .tif images of the original log. The data was digitized using Neurolog v.2015.12 (NeuraLog.com). This process involves tracing each log over a user-defined...
