(Ethnobotany database)

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.

Often grows in clonal colonies [1] — look around for other stems!

A clonal colony of quaking aspen in Utah called Pando is thought to be at least old. [2] [3]

Aspen is well-adapted to 🔥︎ fire — after a fire, it produces new trunks from its roots or trunk base.

Aspen often grows with jack pine  Pinus banksiana — after a fire, both grow fast and eventually would get ⛱ shaded out by spruce  genus Picea and fir  genus Abies, until again invig­or­ated by the next cycle of fire.
