Service Description: In the early 1800s, surveyors used “bearing trees,” many of them oaks, as landmarks. How many are still with us, as living witnesses to our history? All you need is a smartphone to help us find out. You don’t need to know anything about trees or maps to become part of this living history project.
In this project, we're asking Illinois residents to visit the sites of bearing trees located on their property or on public property and record information about any remaining witness trees left in Illinois, using the the map below. Note: Please do not enter private property unless you have permission or hike off maintained trails!)

All other PLS data in Illinois was transcribed by 37 individuals from Jason McLachlan's lab at the University of Notre Dame as part of the PalEON Project (www.paleonproject.org).
