Is there a list or table of native trees that are shallow rooted?

Expert Response

May I ask why you want this list?  It is a misconception that trees have a deep taproot.  Instead, picture a wine glass.  The bowl is the canopy (branches and leaves).  The stem of the glass is the trunk.  The base is the way the roots grow.  Roots are mostly within the top 18 inches  of the surface.  There is an illustration in the link under Measuring Tree Root Spread.  https://extension.umn.edu/planting-and-growing-guides/watering-established-trees-and-shrubs#measuring-tree-root-spread-1261762
