Habitat:Quaking
aspens occur on a variety of soils, from moist, loamy sand to shallow, rocky
soils and clay, on bottomlands and on upland slopes. An aggressive pioneer
plant, it seeds into recently burned sites on exposed mineral soils. It
is very intolerant of shade, growing best in full sun on rich, porous limestone
soils.
Diseases: Like most poplars, this species is susceptible to a number of diseases which can quickly debilitate trees, including heart rot, cankers, dieback and leaf diseases. Poplar borer, poplar tent caterpillar and scales may be problematic.
Distribution:Native from Labrador to Alaska, south to Pennsylvania, Missouri, northern Mexico and California, this species is the most widely-distributed North American tree. It is common in eastern Iowa and found scattered along principal river valleys in southern and western Iowa.
