Quaking Aspen
Populus tremuloides

Quaking Aspen is the most abundant and widespread tree in Minnesota today and the most common Populus species in North America. The huge stands across northern Minnesota are the result of clear cutting our expansive pine forests a century ago. Fire suppression has also allowed it to expand into historical prairie habitats were subsoil moisture is adequate to sustain it through dry periods. In the winter months its bark could be confused with other Populus species but its small, shiny and hairless buds that are not coated with resin distinguishes it from other similar species. Used primarily for reforesting an area quickly due to its pioneer qualities, especially in cut-over and burned areas.
