Tree care · Mountain West
Wyoming is high, dry and windy, with cold winters, warm summers and big swings between day and night temperatures. Towns rely on hardy planted trees like cottonwoods, ash, elms and blue spruce, while ponderosa pine, lodgepole pine and aspen grow in the hills and mountains. Wind, snow load, hail and wildfire risk shape most tree work.
