Pinus hosts caterpillars of 247 species
of butterflies and moths, in some areas.

Jack pine requires 🔥︎ fire to 🌱︎ germinate, to melt the sap in their very-tough seratonous (resin-filled) cones, releasing the seeds.  Thus, jack pine forests are often composed of trees all the same age, all 🌱︎ germinated together after a fire moved through (and perhaps killed their parents).  Jack pine often grows with aspen/cottonwood/poplar leaves  genus Populus —after a fire, both grow fast and eventually would get shaded out by spruce and fir, until again invigorated by the next cycle of fire.
