Uses by native peoples
(Ethnobotany database)

Pinus hosts caterpillars of 247 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.

Seeds from this tree's cones are an important food source for 🐻︎ bears and other animals.

But the tree is having a tough time lately, even in 🏞 Yellowstone National Park, attacked by diseases no longer suppressed by  harsh winter weather.  The trees are probably trying to compensate by moving up in altitude, but that process is slow if you are a tree.  And impossible if you have reached 🗻︎ the top of nearby terrain.
