Uses by native peoples
(Ethnobotany database)
  A superdense hardwood, very durable, with a dark grain.  In WWI, the wood from American walnut was highly valued for making airplane propellers and gunstocks.  Its wood is currently valued for furniture and cabinets.

Juglans hosts caterpillars of 130 species
of butterflies and moths, in some areas.
  This plant is also known to be a host for (in areas where invasive) 🐝︎ spotted lanternfly (SLF)  Lycorma delicatula.

This tree produces a ☠︎ toxic[?] substance that prevents many plants from growing under or near them.

On the other hand, 🌾︎ grass turf lawn still seems to grow underneath.  On the third hand, back when I owned one, before mowing or playing soccer / lacrosse / whatever, this author had to walk the lawn and kick any walnuts off to the side.

And our neighbors still cannot get 🍅︎ tomatoes to bear fruit in soil beneath their mature black walnut tree, after they cut it down!
