Examples include quaking aspen and red osier dogwood. The soil texture range indicates what soil textures a particular plant requires. Sand is the largest particle, silt intermediate, and clay the smallest. Soils have different textures depending on the proportions of sand, silt, or clay particles. The drainage range indicates what soil drainage conditions a species can tolerate.
Soil drainage is a relationship between water in the soil and topography.
Flooded - In these areas, standing water is present most of the growing season. Wet - These are areas where standing water is present most of the growing season, except during times of drought. Wet areas are found at the edges of ponds, rivers, streams, ditches, and low spots. Wet conditions often exist on poorly drained soils with a high clay content. Moist - These are areas where the soil is damp.
